ABSTRACT

BACKGROUND: Age is a major risk factor for venous thromboembolism (VTE), yet patients aged ≥90 years are under-represented in clinical trials of anticoagulant therapy. The objectives were to describe and compare patient clinical characteristics, treatments, and outcomes (VTE recurrence, bleeding, and mortality) during the first 3 months of anticoagulation between VTE patients aged ≥90 years and those aged <90

METHODS: We analyzed data from the Registro Informatizado Enfermedad TromboEmbὀlica (RIETE), an ongoing global observational registry of patients with objectively confirmed acute VTE.

RESULTS: From January 2001 to October 2022, 96,701 patients were registered in RIETE, of whom 3262 (3.4%) were aged ≥90 years. Patients aged ≥90 years were less likely to be men, and to have experienced cancer or recent surgery, but more likely to manifest immobility, chronic heart failure, anemia, renal insufficiency, or dementia than those aged <90

CONCLUSIONS: In patients aged ≥90 years, the difference in the outcome of anticoagulant treatment depending on the initial presentation of VTE could suggest a need for different management approaches. Clinical trials evaluating the optimal duration of anticoagulation according to initial VTE presentation are warranted to limit excess deaths in this particular population.

Inhibition of Factor XI: A New Era in the Treatment of Venous Thromboembolism in Cancer Patients?

Int J Mol Sci. 2023 Sep 22;24(19):14433. doi: 10.3390/ijms241914433.

ABSTRACT

Direct oral anticoagulants against activated factor X and thrombin were the last milestone in thrombosis treatment. Step by step, they replaced antivitamin K and heparins in most of their therapeutic indications. As effective as the previous anticoagulant, the decreased but persistent risk of bleeding while using direct oral anticoagulants has created space for new therapeutics aiming to provide the same efficacy with better safety. On this basis, drug targeting factor XI emerged as an option. In particular, cancer patients might be one of the populations that will most benefit from this technical advance. In this review, after a brief presentation of the different factor IX inhibitors, we explore the potential benefit of this new treatment for cancer patients.

Nuclear medicine imaging methods of early radiation-induced cardiotoxicity: a ten-year systematic review

Front Oncol. 2023 Oct 9;13:1240889. doi: 10.3389/fonc.2023.1240889. eCollection 2023.

ABSTRACT

INTRODUCTION: Radiotherapy has significantly improved cancer survival rates, but it also comes with certain unavoidable complications. Breast and thoracic irradiation, for instance, can unintentionally expose the heart to radiation, leading to damage at the cellular level within the myocardial structures. Detecting and monitoring radiation-induced heart disease early on is crucial, and several radionuclide imaging techniques have shown promise in this regard.

METHOD: In this 10-year review, we aimed to identify nuclear medicine imaging modalities that can effectively detect early cardiotoxicity following radiation therapy. Through a systematic search on PubMed, we selected nineteen relevant studies based on predefined criteria.

RESULTS: The data suggest that incidental irradiation of the heart during breast or thoracic radiotherapy can cause early metabolic and perfusion changes. Nuclear imaging plays a prominent role in detecting these subclinical effects, which could potentially serve as predictors of late cardiac complications.

DISCUSSION: However, further studies with larger populations, longer follow-up periods, and specific heart dosimetric data are needed to better understand the relationship between early detection of cardiac abnormalities and radiation-induced heart disease.

CXCL10 deficiency limits macrophage infiltration, preserves lung matrix, and enables lung growth in bronchopulmonary dysplasia

Inflamm Regen. 2023 Oct 24;43(1):52. doi: 10.1186/s41232-023-00301-6.

ABSTRACT

Preterm infants with oxygen supplementation are at high risk for bronchopulmonary dysplasia (BPD), a neonatal chronic lung disease. Inflammation with macrophage activation is central to the pathogenesis of BPD. CXCL10, a chemotactic and pro-inflammatory chemokine, is elevated in the lungs of infants evolving BPD and in hyperoxia-based BPD in mice. Here, we tested if CXCL10 deficiency preserves lung growth after neonatal hyperoxia by preventing macrophage activation. To this end, we exposed Cxcl10 knockout (Cxcl10-/-) and wild-type mice to an experimental model of hyperoxia (85% O2)-induced neonatal lung injury and subsequent regeneration. In addition, cultured primary human macrophages and murine macrophages (J744A.1) were treated with CXCL10 and/or CXCR3 antagonist. Our transcriptomic analysis identified CXCL10 as a central hub in the inflammatory network of neonatal mouse lungs after hyperoxia. Quantitative histomorphometric analysis revealed that Cxcl10-/- mice are in part protected from reduced alveolar. These findings were related to the preserved spatial distribution of elastic fibers, reduced collagen deposition, and protection from macrophage recruitment/infiltration to the lungs in Cxcl10-/- mice during acute injury and regeneration. Complimentary, studies with cultured human and murine macrophages showed that hyperoxia induces Cxcl10 expression that in turn triggers M1-like activation and migration of macrophages through CXCR3. Finally, we demonstrated a temporal increase of macrophage-related CXCL10 in the lungs of infants with BPD. In conclusion, our data demonstrate macrophage-derived CXCL10 in experimental and clinical BPD that drives macrophage chemotaxis through CXCR3, causing pro-fibrotic lung remodeling and arrest of alveolarization. Thus, targeting the CXCL10-CXCR3 axis could offer a new therapeutic avenue for BPD.

Low-Dose Rivaroxaban to Prevent Recurrences of Venous Thromboembolism in Cancer: A Real-Life Experience with a Focus on Female Patients

J Clin Med. 2023 Oct 9;12(19):6427. doi: 10.3390/jcm12196427.

ABSTRACT

BACKGROUND: The way in which to prevent recurrent venous thromboembolism (VTE) is an unmet clinical need in cancer patients. International guidelines only provide conditional recommendations and do not specify which anticoagulant and dose should be used. In the last 2 years, we have been using low-dose rivaroxaban to prevent VTE recurrences in cancer patients. The results of this real-life experience are presented in this study.

METHODS: All patients had cancer and had previously completed a cycle of at least six months of full-dose anticoagulation for the treatment of a VTE index event, before receiving a prescription of low-dose rivaroxaban (10 mg once daily) for secondary prevention of VTE. Effectiveness and safety of this therapeutic regimen were evaluated in terms of VTE recurrences, major bleedings (MB), and clinically relevant non-major bleedings (CRNMB).

RESULTS: The analysis included 106 cancer patients. Their median age was 60 years (IQR 50-69). Metastatic cancer was present in 87 patients (82.1%). Six patients (5.7%) had brain metastases. Over a median follow-up time of 333 days (IQR 156-484), the incidence of VTE recurrences was 3.8% (95%CI 1.0-9.4), with a recurrence rate of 4.0 per 100 person-years (95%CI 1.1-10.2). We observed no MB (0.0%) and three CRNMB (2.8%) (95%CI 0.6-8.1).

CONCLUSIONS: Low-dose rivaroxaban is potentially effective and safe in cancer patients that require prevention of recurrent VTE. Large-scale studies are needed to confirm these findings.

Microparticles and cardiotoxicity secondary to doxorubicin-based chemotherapy in breast cancer patients

Int J Cardiol. 2023 Oct 16:131435. doi: 10.1016/j.ijcard.2023.131435. Online ahead of print.

ABSTRACT

Doxorubicin (DOXO)-cardiotoxicity is a limiting factor for breast cancer chemotherapy. The relationship between microparticles (MPs) and cardiotoxicity remains unclear. MPs can be released under varying pathophysiological conditions. Thereby, this study aimed to assess MPs derived from cardiomyocytes (CardioMPs), platelets (PMPs) and those that expresses tissue factor (TFMPs) in 80 women with breast cancer undergoing DOXO-based chemotherapy, with or without cardiotoxicity in a one-year follow-up. We observed in the cardiotoxicity group higher count of total-MPs at T0 (prior chemotherapy) (p = 0.034), CardioMPs at T0 and T1 (just after chemotherapy) (p = 0.009 and p = 0.0034) and TFMPs at T0 (p = 0.011) compared to non-cardiotoxicity group. The results suggest that MPs could be associated to cardiotoxicity due to DOXO treatment in breast cancer patients.

Risk of Thrombosis and Bleeding in Gynecologic Cancer Surgery: Systematic Review and Meta-Analysis

Am J Obstet Gynecol. 2023 Oct 10:S0002-9378(23)00735-4. doi: 10.1016/j.ajog.2023.10.006. Online ahead of print.

ABSTRACT

OBJECTIVE: To provide procedure-specific estimates of the risk of symptomatic venous thromboembolism (VTE) and major bleeding, in the absence of thromboprophylaxis, following gynecologic cancer surgery.

DATA SOURCES: We conducted comprehensive searches on Embase, MEDLINE, Web of Science, and Google Scholar for observational studies. We also reviewed reference lists of eligible studies and review articles. We performed separate searches for randomized trials addressing effects of thromboprophylaxis and conducted a web-based survey on thromboprophylaxis practice.

STUDY ELIGIBILITY CRITERIA: Observational studies enrolling ≥50 adult patients undergoing gynecologic cancer surgery procedures reporting absolute incidence for at least one of the following: symptomatic pulmonary embolism, symptomatic deep vein thrombosis, symptomatic VTE, bleeding requiring reintervention (including re-exploration and angioembolization), bleeding leading to transfusion or post-operative hemoglobin <70

STUDY APPRAISAL AND SYNTHESIS METHODS: Two reviewers independently assessed eligibility, performed data extraction, and evaluated risk of bias of eligible articles. We adjusted the reported estimates for thromboprophylaxis and length of follow-up and used the median value from studies to determine cumulative incidence at 4 weeks post-surgery stratified by patient VTE risk factors, and used the GRADE approach to rate evidence certainty.

RESULTS: We included 188 studies (398,167 patients) reporting on 37 gynecologic cancer surgery procedures. The evidence certainty was generally low to very low. Median symptomatic VTE risk (in the absence of prophylaxis) was <1%2.0% in 13 of 37 (35%). The risks of VTE varied from 0.1% in low VTE risk patients undergoing cervical conization to 33.5% in high VTE risk patients undergoing pelvic exenteration. Estimates of bleeding requiring reintervention varied from <0.1%<1%

CONCLUSIONS: VTE reduction with thromboprophylaxis likely outweighs increase in bleeding requiring reintervention in many gynecologic cancer procedures (e.g., open surgery for ovarian cancer and pelvic exenteration). In some procedures (e.g., laparoscopic total hysterectomy without lymphadenectomy), thromboembolism and bleeding risks are similar, and decisions depend on individual risk prediction and values and preferences regarding VTE and bleeding.

Risk factors for bleeding in cancer patients treated with conventional dose followed by low dose apixaban for venous thromboembolism

Thromb Haemost. 2023 Oct 10. doi: 10.1055/a-2188-8773. Online ahead of print.

ABSTRACT

BACKGROUND: Incidence of and risk factors for bleeding in cancer patients with venous thromboembolism (VTE) treated with apixaban are poorly described.

METHODS: We analyzed data from the prospective CAP study where 298 cancer patients with any type of VTE received 5 mg apixaban twice daily for 6 months, and then 2.5 mg apixaban twice daily for 30 months. For most analyses major bleedings and clinically relevant non-major bleedings were merged to "clinically relevant bleedings". Risk factors were estimated by odds ratios (OR) and 95% confidence intervals (CI).

RESULTS: The incidence of clinically relevant bleedings was 38% per person year during the first 6 months of treatment, 21% per person year from 7 to 12 months, and between 4% and 8% per person year from 13 to 36 months. Clinically relevant bleedings were associated with age above 74 years (OR 2.0, 95% CI 1.0-4.1), BMI below 21.7 (OR 2.3, 95% CI 1.1-4.8), and hemoglobin at baseline below 10.5 for females (OR 2.8, 95% CI 1.1-7.3) and 11.1 for males (OR 3.3, 95% CI 1.3-8.4) during the first 6 months. Gastrointestinal (GI) or urogenital cancer were not associated with clinically relevant bleedings compared with other cancers. Among patients with luminal GI-cancer, non-resected cancer had increased risk of bleeding (OR 3.4, 95% CI 1.0-11.6) compared with resected GI-cancer.

CONCLUSION: It was very few bleedings while patients were on low-dose apixaban. Factors associated with bleeding in patients treated with full-dose apixaban were high age, low BMI, and low hemoglobin, and probably non-resected luminal GI-cancer.

A multifaceted quality improvement intervention on venous thromboembolism prophylaxis compliance in hospitalized medical patients at a comprehensive cancer center

J Oncol Pharm Pract. 2023 Oct 6:10781552231205779. doi: 10.1177/10781552231205779. Online ahead of print.

ABSTRACT

INTRODUCTION: Previous studies suggest that quality improvement initiatives focused on hospital-acquired venous thromboembolism have a positive impact on prescribing rates of venous thromboembolism prophylaxis, especially those that incorporate computerized changes.

METHODS: We conducted a quality improvement project to determine whether education and computerized prescriber order entry system changes affect venous thromboembolism prophylaxis compliance rates in hospitalized medical patients at a Comprehensive Cancer Center. Between 1 January 2021 and 31 January 2023, 37,739 non-surgical, adult patient encounters with a length of stay > 48 h were analyzed in our study. From 18 December 2021 to 8 March 2022, provider education was delivered to the three largest admitting services, and computerized prescriber order entry changes were implemented incorporating a mandatory requirement to either order venous thromboembolism prophylaxis or document a contraindication for all patients at moderate venous thromboembolism risk.

RESULTS: Monthly venous thromboembolism prophylaxis compliance rates, as defined by the Centers for Medicare and Medicaid Services VTE-1 metric, increased from a mean of 74% to 93% after the interventions. This change was driven primarily by an increased utilization of mechanical venous thromboembolism prophylaxis from 37% to 53%.

CONCLUSION: Our study demonstrated that a multi-faceted intervention incorporating provider education and computerized prescriber order entry system changes can significantly increase venous thromboembolism prophylaxis compliance rates in cancer patients.

Impact of venous thromboembolism on the mortality in patients with cancer: a population-based cohort study

Lancet Reg Health Eur. 2023 Sep 28;34:100739. doi: 10.1016/j.lanepe.2023.100739. eCollection 2023 Nov.

ABSTRACT

BACKGROUND: Despite recent improvements in the treatment of cancer, little is known about the long-term survival in patients with cancer and venous thromboembolism. We aimed to examine the five-year mortality of venous thromboembolism in cancer patients in a large population-based cohort study.

METHODS: Using Danish healthcare registries from 1995 to 2020, we obtained data on cancer patients with venous thromboembolism and comparison cohorts of cancer patients without venous thromboembolism, matched in terms of cancer type, age, sex, and year of cancer diagnosis, and adjusted for level of comorbidity and frailty using the Charlson Comorbidity Index Score and Hospital Frailty Risk Score, marital status, use of selected medications, and recent surgery (<90

FINDINGS: During the study period, 886,536 patients were diagnosed with cancer. Of 1882 cancer patients diagnosed at the time of their venous thromboembolism, 44.4% (835/1882) had distant metastases. In this cohort, the one- and five-year mortality cumulative incidences were 68% (1284/1882) and 84% (1578/1882), respectively, in contrast to 38% (2135/5549) and 67% (3653/5549) in the comparison cohort. The mortality rate ratio was 4.34 (95% confidence interval [CI], 3.95-4.78) for the first year of follow-up and 3.44 (95% CI 3.17-3.73) for the five-year follow-up period. Of the 23,366 patients diagnosed with venous thromboembolism after cancer diagnosis, 18% (4183/23,366) had distant metastases at the time of cancer diagnosis. The cumulative incidence of death at one year was 45% (10,465/23,366; mortality rate ratio 3.48, 95% CI 3.37-3.60) and at five years 69% (15,669/23,366; mortality rate ratio 2.57, 95% CI 2.50-2.63).

INTERPRETATION: Despite improved cancer treatment, venous thromboembolism in cancer patients is strongly associated with a poor prognosis.

FUNDING: The study was supported by grants from the Independent Research Fund Denmark (record no. 3101-00102B) and the Karen Elise Jensen Foundation.

Acute venous thromboembolism in patients with brain cancer: clinical course

Res Pract Thromb Haemost. 2023 Aug 20;7(6):102172. doi: 10.1016/j.rpth.2023.102172. eCollection 2023 Aug.

ABSTRACT

BACKGROUND: Patients with brain cancer have been excluded or were underrepresented in studies on the treatment of venous thromboembolism (VTE), mainly due to the fear of intracranial hemorrhage (ICH).

OBJECTIVES: The aim of this study was to provide data on the risk of ICH, recurrent VTE, and major bleeding in patients with active brain cancer.

METHODS: This was a multicenter, international cohort study at participating sites of the Registro Informatizado Enfermedad Tromboembólica Registry. Patients included in this study were classified as having known active brain cancer, active nonbrain cancer, or without active cancer. ICH at 3 months was the primary study outcome.

RESULTS: Overall, 98,377 patients with VTE were included: 616 with active brain cancer, 16,807 with active nonbrain cancer, and 80,954 without active cancer. At 3 months follow-up, ICH occurred in 2.8%, 0.3%, and 0.2% of the patients, respectively, and was fatal in 1.3%, 0.2%, and 0.1%, respectively. Both rates of major bleeding (3.7% vs 3.2% vs 1.5%, respectively) and recurrent VTE (3.9% vs 3.4% vs 1.1%, respectively) were higher in patients with brain or nonbrain cancer than in patients without cancer. Glioblastomas were associated with a numerically higher risk of ICH, fatal ICH, and recurrent VTE than other brain tumors.

CONCLUSION: In patients with VTE, active brain cancer was associated with a higher risk of ICH or fatal ICH than nonbrain or no active cancer. Further studies are needed to assess the value of different treatment approaches in patients with brain cancer and VTE.

Incident Cardiovascular Disease Risk Among Older Asian, Native Hawaiian and Pacific Islander Breast Cancer Survivors

Cancer Epidemiol Biomarkers Prev. 2023 Oct 16. doi: 10.1158/1055-9965.EPI-23-0679. Online ahead of print.

ABSTRACT

BACKGROUND: Cardiotoxicity among breast cancer survivors is associated with chemotherapy and radiation therapy. The risk of cardiovascular disease (CVD) among Asian, Native Hawaiian and Pacific Islander (ANHPI) breast cancer survivors in the US is unknown.

METHODS: We used the SEER-Medicare linked database to estimate the risk of CVD among older breast cancer survivors. ICD diagnosis codes were used to identify incident CVD outcomes. Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) comparing ANHPI to Non-Hispanic White (NHW) breast cancer patients for CVD, and among ANHPI race and ethnicity groups.

RESULTS: A total of 7,122 ANHPI breast cancer survivors and 21,365 NHW breast cancer survivors were identified. The risks of incident heart failure and ischemic heart disease were lower among ANHPI compared to NHW breast cancer survivors (HRheart failure=0.72, 95%CI=0.61, 0.84; HRheart disease=0.74, 95%CI=0.63, 0.88). Compared to Japanese breast cancer patients, Filipino, Asian Indian and Pakistani, and Native Hawaiian breast cancer survivors had higher risks of heart failure. ischemic heart disease and death. Among ANHPI breast cancer survivors, risk factors for heart failure included older age, higher comorbidity score, distant cancer stage and chemotherapy.

CONCLUSIONS: Our results support heterogeneity in CVD outcomes among breast cancer survivors among ANHPI race and ethnicity groups. Further research is needed to elucidate the disparities experienced among ANHPI cancer survivors.

IMPACT: Filipino, Asian Indian and Pakistani, and Native Hawaiian breast cancer patients had higher risks of heart failure, ischemic heart disease and death among ANHPI breast cancer patients.

Increased risk of venous and arterial thromboembolism in patients with colorectal cancer receiving cetuximab-based combination chemotherapy: A population-based study in Korea

Thromb Res. 2023 Oct 4;231:50-57. doi: 10.1016/j.thromres.2023.10.005. Online ahead of print.

ABSTRACT

INTRODUCTION: Limited data exist on the risk of venous and arterial thromboembolisms (VTE and ATE) in patients receiving cetuximab plus chemotherapy. We aimed to determine the thromboembolic risk of patients with recurrent/metastatic colorectal cancer (CRC) treated with cetuximab plus chemotherapy compared to chemotherapy alone.

METHODS: This population-based study used nationwide claims data from the Health Insurance Review and Assessment Service of South Korea from 2013 to 2020. Patients with recurrent/metastatic CRC treated with first-line oxaliplatin- or irinotecan-based doublets with or without cetuximab and no secondary prevention for VTE and ATE were included. Primary outcomes were the occurrence of any thromboembolic events, VTE, and ATE, which were determined using the cumulative incidence method incorporating death as a competing event.

RESULTS: We identified 19,723 patients (cetuximab plus chemotherapy, N = 7630; chemotherapy alone, N = 12,093). The cumulative incidence of any thromboembolic events in patients with cetuximab plus chemotherapy was significantly higher than in those receiving chemotherapy alone (6-month, 5.62 % vs. 3.58 %, P < 0.0001). The rates of VTE (6-month, 5.11 % vs. 3.28 %, P < 0.0001) and ATE (6-month, 0.53 % vs. 0.32 %, P = 0.0218) were also higher in patients receiving cetuximab plus chemotherapy. In multivariable analysis, cetuximab plus chemotherapy was independently associated with developing any thromboembolic events (hazard ratio [HR], 1.63; 95 % confidence interval [CI], 1.42-1.87), VTE (HR, 1.62; 95 % CI, 1.40-1.87), and ATE (HR, 1.77; 95 % CI, 1.16-2.71).

CONCLUSIONS: Cetuximab with irinotecan- or oxaliplatin-based doublet chemotherapy was associated with an increased risk of any thromboembolic events, VTE, and ATE; further studies are warranted to examine the underlying mechanisms.

Complications of Central Venous Access Devices Used in Palliative Care Settings for Terminally Ill Cancer Patients: A Systematic Review and Meta-Analysis

Cancers (Basel). 2023 Sep 25;15(19):4712. doi: 10.3390/cancers15194712.

ABSTRACT

(1) Background: Central venous access devices (CVADs) have been commonly employed during various courses of anticancer treatment. Currently, there are a few types of clinically available CVADs, which are associated with short-term and long-term complications. However, little is known about the complication rates when CVADs are used only in palliative care settings. We therefore performed a systematic review and meta-analysis of all the published literature to evaluate the complication rates of CVADs in this clinical setting. (2) Methods: A systematic review and meta-analysis were conducted to identify publications from PubMed/MEDLINE, Embase (Ovid), Scopus, Cochrane Library, CINAHL, Google Scholar, and trial registries. Publications reporting the complication rates of PICCs, central lines, and PORTs in palliative settings for terminally ill cancer patients were included, while those on the use of systemic anticancer therapy and peripheral venous catheters were excluded. The outcome measures included overall complication rate, rate of catheter-related bloodstream infection (CRBSI), and rate of thromboembolism (TE). This systematic review was registered with PROSPERO (CRD42023404489). (3) Results: Five publications with 327 patients were analyzed, including four studies on PICCs and one study on central lines. No studies on PORTs were eligible for analysis. The overall complication rate for PICCs (pooled estimate 7.02%, 95% CI 0.27-19.10) was higher than that for central lines (1.44%, 95% CI 0.30-4.14, p = 0.002). The risk of CRBSI with PICCs (2.03%, 95% CI 0.00-9.62) was also higher than that with central lines (0.96%, 95% CI 0.12-3.41, p = 0.046). PICCs also had a trend of a higher risk of TE (2.10%, 95% CI 0.00-12.22) compared to central lines (0.48%, 95% CI 0.01-2.64, p = 0.061). (4) Conclusions: PICCs for palliative cancer care were found to have greater complications than central lines. This might aid in the formulation of future recommendation guidelines on the choice of CVAD in this setting.

High-resolution and quantitative spatial analysis reveal intra-ductal phenotypic and functional diversification in pancreatic cancer

J Pathol. 2023 Oct 16. doi: 10.1002/path.6212. Online ahead of print.

ABSTRACT

A 'classical' and a 'basal-like' subtype of pancreatic cancer have been reported, with differential expression of GATA6 and different dosages of mutant KRAS. We established in situ detection of KRAS point mutations and mRNA panels for the consensus subtypes aiming to project these findings to paraffin-embedded clinical tumour samples for spatial quantitative analysis. We unveiled that, next to inter-patient and intra-patient inter-ductal heterogeneity, intraductal spatial phenotypes exist with anti-correlating expression levels of GATA6 and KRASG12D . The basal-like mRNA panel better captured the basal-like cell states than widely used protein markers. The panels corroborated the co-existence of the classical and basal-like cell states in a single tumour duct with functional diversification, i.e. proliferation and epithelial-to-mesenchymal transition respectively. Mutant KRASG12D detection ascertained an epithelial origin of vimentin-positive cells in the tumour. Uneven spatial distribution of cancer-associated fibroblasts could recreate similar intra-organoid diversification. This extensive heterogeneity with functional cooperation of plastic tumour cells poses extra challenges to therapeutic approaches. © 2023 The Authors.

Enoxaparin for the long-term therapy of venous thromboembolism in patients with cancer and renal insufficiency

Thromb Haemost. 2023 Oct 13. doi: 10.1055/a-2191-7510. Online ahead of print.

ABSTRACT

BACKGROUND: The optimal therapy of venous thromboembolism (VTE) in cancer patients with renal insufficiency (RI) is unknown. Current guidelines recommend to use low-molecular-weight heparin over direct oral anticoagulants to treat VTE in cancer patients at high-risk for bleeding.

METHODS: We used the RIETE registry to compare the 6-month incidence rates of: 1) VTE recurrences vs. major bleeding; and 2) fatal pulmonary embolism (PE) vs. fatal bleeding in 3 subgroups (those with mild, moderate, or severe RI) of cancer patients receiving enoxaparin monotherapy.

RESULTS: From January 2009 through June 2022, 2,844 patients with RI received enoxaparin for ≥6 months: 1,432 (50%) had mild, 1,168 (41%) moderate, and 244 (8.6%) had severe RI. Overall, 68%, 62% and 12% respectively, received the recommended doses. Among patients with mild RI, the rates of VTE recurrences vs. major bleeding (4.6% vs. 5.4%) and fatal PE vs. fatal bleeding (1.3% vs. 1.2%) were similar. Among patients with moderate RI, VTE recurrences were half as common as major bleeding (3.1% vs. 6.3%), but fatal PE and fatal bleeding were close (1.8% vs. 1.2%). Among patients with severe RI, VTE recurrences were 3-fold less common than major bleeding (4.1% vs. 13%), but fatal PE was 3-fold more frequent than fatal bleeding (2.5% vs. 0.8%). During the first 10 days, fatal PE was 5-fold more common than fatal bleeding (2.1% vs. 0.4%).

CONCLUSIONS: Among cancer patients with severe RI, fatal PE was 5-fold more common than fatal bleeding. The recommended doses of enoxaparin in these patients should be revisited.

Cancer and Atrial Fibrillation Comorbidities Among 25 Million Citizens in Shanghai, China: Medical Insurance Database Study

JMIR Public Health Surveill. 2023 Oct 17;9:e40149. doi: 10.2196/40149.

ABSTRACT

BACKGROUND: With population aging, the prevalence of both cancer and atrial fibrillation (AF) have increased. However, there is scarce epidemiological data concerning the comorbid state of cancer and AF in low- and middle-income countries, including China.

OBJECTIVE: We aimed to evaluate the site-, sex-, and age-specific profiles of cancer and AF comorbidities in Chinese populations.

METHODS: Data from the Shanghai Municipal Health Commission database between 2015 and 2020 were screened, covering all medical records of Shanghai residents with medical insurance. Site-specific cancer profiles were evaluated for the population with AF relative to the age- and sex-adjusted population of residents without AF. The sex distribution and peak age of cancer diagnosis were also assessed.

RESULTS: A total of 25,964,447 adult patients were screened. Among them, 22,185 patients presented cancers comorbid with AF (median 77, IQR 67-82 years of age; men: n=13,631, 61.44%), while 839,864 presented cancers without AF (median 67, IQR 57-72 years of age; men: n=419,020, 49.89%), thus yielding a higher cancer prevalence among residents with AF (8.27%) than among those without AF (6.05%; P<.001).

CONCLUSIONS: Patients with AF are associated with increased prevalence, heightened male predominance, and younger peak age of cancer. Further studies are needed to determine whether early screening of specific cancers is cost-effective and beneficial for patients with AF.

Smoking, Diabetes Mellitus, and Previous Cardiovascular Disease as Predictors of Anticancer Treatment-Induced Cardiotoxicity in Non-Small-Cell Lung Cancer: A Real-World Study

Clin Lung Cancer. 2023 Oct 4:S1525-7304(23)00187-0. doi: 10.1016/j.cllc.2023.09.007. Online ahead of print.

ABSTRACT

PURPOSE: Cardiotoxicity is a common and under-reported side effect of tyrosine-kinase inhibitors (TKI) and immune checkpoint inhibitors (ICI). Baseline risk factors may help in risk-stratifying patients at increased risk of cardiotoxicity. This real-world study investigated the effects of baseline risk factors in cardiotoxicity on patients with non-small-cell lung cancer (NSCLC) treated with TKIs and ICIs.

METHODS: This is a retrospective study carried out at The Royal Marsden Hospital, UK. Newly diagnosed patients with localized or metastatic NSCLC who received anticancer therapy with TKIs and/or ICIs were eligible. Patients who received only chemotherapy were excluded. Patients were followed up from the time of diagnosis until death or discharge. The relationship between cardiotoxicity and risk factors were tested by logistic regression.

RESULTS: Of 88/451 (19.5%) patients developed cardiotoxicity. Risk factors hypothesized to have a causal relationship with anticancer treatment-induced cardiotoxicity were analyzed. Cardiotoxicity risk was increased with prior diabetes mellitus (OR = 1.93, 95% CI, 1.04-3.61, P = .038), history of smoking (OR = 1.91, 95% CI, 1.13-3.22, P = .016) and presence of baseline cardiovascular disease (OR = 2.03, 95% CI, 1.13-3.64, P = .018). The risk of developing cardiotoxicity increased in patients for smokers with diabetes mellitus (OR = 3.03, 95% CI, 1.40-6.55, P < .01) and for smokers with previous cardiovascular disease (OR = 1.99, 95% CI, 1.03-3.84, P = .041).

CONCLUSION: Diabetes mellitus, smoking and baseline cardiovascular disease may synergistically contribute to cardiotoxicity when a patient is exposed to potentially cardiotoxic anticancer agents. Risk stratification at baseline may improve cardio-oncology care.

A - 119 A Case Study: the Cognitive Functioning of an Adult Patient with Recurrent Craniopharyngiomas

Arch Clin Neuropsychol. 2023 Oct 20;38(7):1291. doi: 10.1093/arclin/acad067.136.

ABSTRACT

OBJECTIVE: Craniopharyngiomas are extremely rare (incidence rate of 1.34 per million). Due to its proximity to the sellar/suprasellar prefrontal regions region, cognitive impairment, behavioral changes, and adverse endocrinological outcomes are common. Further, surgery and radiotherapy can further impact functioning. Currently, there is no parsimonious cognitive profile of adult patients following interventions. This case highlights the role of neuropsychological evaluations in monitoring global psychological functioning and frontal behavioral syndrome in an adult with recurrent craniopharyngioma.

METHOD: The patient is a 39-year-old Black female first evaluated as an inpatient prior to resection surgery. She was evaluated on four additional times post-surgically. At the most recent evaluation, she and her family reported memory problems, apathy, and gait instability. Complicating factors included hypothyroidism, chronic kidney disease, diabetes, obstructive sleep apnea, pulmonary embolism, hypotension, COVID-19, and recurrent tachycardia, with inconsistent adherence to treatment recommendations.

RESULTS: She displayed global cognitive deficits two years post-surgery, particularly in language and memory. Neurobehaviorally, she exhibited pervasive signs of severe frontal lobe syndrome, including, abulia, hypophonic and dysarthric speech, psychomotor retardation, bradyphrenia, and anosognosia.

CONCLUSION: Neuropsychological evaluations remain critical in monitoring the patient's neurocognitive status and provide valuable insights into treatment planning and need for additional support and care to optimize patients' quality of life in the context of significant cognitive disability.

Venous thromboembolism prevention in cancer care: implementation strategies to address underuse

Res Pract Thromb Haemost. 2023 Aug 20;7(7):102173. doi: 10.1016/j.rpth.2023.102173. eCollection 2023 Oct.

ABSTRACT

BACKGROUND: Evidenced-based interventions have been developed to prevent venous thromboembolism (VTE) in ambulatory patients with cancer, including VTE-risk assessment for all patients and targeted primary thromboprophylaxis for high-risk patients. Despite supportive evidence and recommendations, oncologists rarely assess VTE risk or provide primary prophylaxis. Our previous work identified barriers and facilitators to using VTE prevention interventions in oncology practice.

OBJECTIVES: To identify potential strategies that address the identified barriers and leverage facilitators to achieve successful implementation of evidence-based interventions for VTE prevention in oncology practice.

METHODS: We used the Implementation Research Logic Model, an implementation science framework, to map the relationships among barriers and facilitators, feasible and effective implementation strategies, and implementation and clinical outcomes that will be used to evaluate the implementation strategies.

RESULTS: We identified 12 discrete implementation strategies (eg, conducting clinician education and training and staged implementation scale-up) that address barriers and leverage facilitators through their mechanisms of action (eg, increased clinician awareness of evidence and targeting the highest effectiveness). We identified key implementation (eg, penetration, adoption, acceptability, fidelity, appropriateness, and sustainability), system (eg, integration of VTE-risk assessment into clinical workflow), and clinical (eg, lower VTE rates) outcomes targeted by the selected strategies.

CONCLUSION: Using the Implementation Research Logic Model framework and building on our knowledge of barriers and facilitators, we identified implementation strategies and important outcomes to evaluate these strategies. We will use these results to test and measure the strategies to improve the uptake of evidence-based recommendations for VTE prevention in oncology practice.

Persistent underuse of extended venous thromboembolism prophylaxis in patients undergoing major abdominal cancer operations

J Surg Oncol. 2023 Oct 6. doi: 10.1002/jso.27473. Online ahead of print.

ABSTRACT

BACKGROUND: Guidelines recommend extended venous thromboembolism (VTE) prophylaxis for high-risk populations undergoing major abdominal cancer operations. Few studies have evaluated extended VTE prophylaxis in the Medicare population who are at higher risk due to age.

METHODS: We performed a retrospective study using a 20% random sample of Medicare claims, 2012-2017. Patients ≥65 years with an abdominal cancer undergoing resection were included. Primary outcome was the proportion of patients receiving new extended VTE prophylaxis prescriptions at discharge. Secondary outcomes included postdischarge VTE and hemorrhagic events.

RESULTS: The study included 72 983 patients with a mean age of 75. Overall, 8.9% of patients received extended VTE prophylaxis. This proportion increased (7.2% in 2012, 10.6% in 2017; p < 0.001). Incidence of postdischarge hemorrhagic events was 1.0% in patients receiving extended VTE prophylaxis and 0.8% in those who did not. The incidence of postdischarge VTE events was 5.2% in patients receiving extended VTE prophylaxis and 2.4% in those who did not.

CONCLUSION: Adherence to guideline-recommended extended VTE prophylaxis in high-risk patients undergoing major abdominal cancer operations is low. The higher rate of VTE in the prophylaxis group may suggest we captured some therapeutic anticoagulation, which would mean the actual rate of thromboprophylaxis is lower than reported herein.

An etiological assessment of a deep vein thrombosis led to the discovery of a renal tumor collision: Case report

Int J Surg Case Rep. 2023 Oct;111:108922. doi: 10.1016/j.ijscr.2023.108922. Epub 2023 Oct 5.

ABSTRACT

INTRODUCTION AND IMPORTANCE: The thromboembolic complication of kidney's tumor is rare, and they can be the reason for the discovery of those tumor. Also the collision kidney tumor, such as a simultaneous occurrence of different histological types of adjacent neoplasms in the same organ is rare.

CASE PRESENTATION: We report a patient diagnosed with a kidney tumor discovered in the context of an etiological assessment of thrombosis, presenting with pulmonary embolism and deep vein thrombosis of the lower limb. This tumor treated by a cytoreductive nephrectomy. The histologic diagnosis of PRCC (Papillary Renal Cell Carcinoma) associated with a chromophobe cell carcinoma and sarcomatoid component was rendered.

CLINICAL DISCUSSION: The development of the tumor process and its progression to the metastatic stage is largely favored by the hypercoagulable state, and the cancer itself promotes the appearance of thrombo-enmbolic phenomena due to this phenomenon. Two major studies recommend that immediate cytoreductive nephrectomy should be offered to metastatic patients with a good general condition.

CONCLUSION: A renal tumor collision is rare, whereas the risk factors for a renal tumor collision are the same as a renal tumor without collision, just as the management of a metastatic renal tumor is the same. Understanding the thromboembolic physiopathology in the case of kidney cancer has made it possible to optimize management.

Outcomes of chronic total occlusion percutaneous coronary intervention from the RAIAN (RAjaie - Iran) registry

Indian Heart J. 2023 Oct 20:S0019-4832(23)00166-9. doi: 10.1016/j.ihj.2023.10.002. Online ahead of print.

ABSTRACT

OBJECTIVE: While most of the evidence in CTO interventions emerge from Western and Japanese studies, few data have been published up today from the Middle East. Objective of this study was to evaluate technical success rates and clinical outcomes of an Iranian population undergoing CTO PCI in a tertiary referral hospital. Moreover, we sought to evaluate the efficacy of our CTO teaching program.

METHODS: This is a retrospective single-center cohort study including 790 patients who underwent CTO PCI performed by operators with different volumes of CTOs PCI performed per year. According to PCI result, all patients have been divided into successful (n = 555, 70.3 %) and unsuccessful (n = 235, 29.7 %) groups. Study endpoints were Major Adverse Cardiovascular Events and Health Status Improvement evaluated using the Seattle Angina Questionnaire at one year.

RESULTS: A global success rate of 70 % for antegrade and 80 % for retrograde approach was shown despite the lack of some CTO-dedicated devices. During the enrollment period, the success rate increased significantly among operators with a lower number of CTO procedures per year. One-year MACE rate was similar in both successful and unsuccessful groups (13.5 % in successful and 10.6 % in unsuccessful group, p = 0.173). One year patients' health status improved significantly only in successful group.

CONCLUSIONS: No significant differences of in-hospital and one-year MACE were found between the successful and unsuccessful groups. Angina symptoms and quality of life significantly improved after successful CTO PCI. The RAIAN registry confirmed the importance of operator expertise for CTO PCI success.

Early Increases in Blood Pressure and Major Adverse Cardiovascular Events in Patients With Renal Cell Carcinoma and Thyroid Cancer Treated With VEGFR TKIs

J Natl Compr Canc Netw. 2023 Oct;21(10):1039-1049.e10. doi: 10.6004/jnccn.2023.7047.

ABSTRACT

BACKGROUND: Although VEGFR tyrosine kinase inhibitors (TKIs) are a preferred systemic treatment approach for patients with advanced renal cell carcinoma (RCC) and thyroid carcinoma (TC), treatment-related cardiovascular (CV) toxicity is an important contributor to morbidity. However, the clinical risk assessment and impact of CV toxicities, including early significant hypertension, among real-world advanced cancer populations receiving VEGFR TKI therapies remain understudied.

METHODS: In a multicenter, retrospective cohort study across 3 large and diverse US health systems, we characterized baseline hypertension and CV comorbidity in patients with RCC and those with TC who are newly initiating VEGFR TKI therapy. We also evaluated baseline patient-, treatment-, and disease-related factors associated with the risk for treatment-related early hypertension (within 6 weeks of TKI initiation) and major adverse CV events (MACE), accounting for the competing risk of death in an advanced cancer population, after VEGFR TKI initiation.

RESULTS: Between 2008 and 2020, 987 patients (80.3% with RCC, 19.7% with TC) initiated VEGFR TKI therapy. The baseline prevalence of hypertension was high (61.5% and 53.6% in patients with RCC and TC, respectively). Adverse CV events, including heart failure and cerebrovascular accident, were common (occurring in 14.9% of patients) and frequently occurred early (46.3% occurred within 1 year of VEGFR TKI initiation). Baseline hypertension and Black race were the primary clinical factors associated with increased acute hypertensive risk within 6 weeks of VEGFR TKI initiation. However, early significant "on-treatment" hypertension was not associated with MACE.

CONCLUSIONS: These multicenter, real-world findings indicate that hypertensive and CV morbidities are highly prevalent among patients initiating VEGFR TKI therapies, and baseline hypertension and Black race represent the primary clinical factors associated with VEGFR TKI-related early significant hypertension. However, early on-treatment hypertension was not associated with MACE, and cancer-specific CV risk algorithms may be warranted for patients initiating VEGFR TKIs.

Tissue factor pathway inhibitor is associated with risk of venous thromboembolism and all-cause mortality in patients with cancer

Haematologica. 2023 Oct 12. doi: 10.3324/haematol.2023.283581. Online ahead of print.

ABSTRACT

Venous thromboembolism (VTE) is a common complication in patients with cancer. Data on the role of natural inhibitors of coagulation for occurrence of cancerassociated VTE are limited, thus, we investigated the association of tissue factor pathway inhibitor (TFPI) with risk of VTE and all-cause mortality in patients with cancer. Total TFPI antigen levels were measured with a commercially available ELISA in patients included in the Vienna Cancer and Thrombosis Study, a prospective observational cohort study with the primary outcome VTE. Competing risk analysis and Cox regression analysis were performed to explore the association of TFPI levels with VTE and all-cause mortality. TFPI was analyzed in 898 patients (median age: 62 years [interquartile range, IQR: 53-68]; 407 [45%] women). Sixtyseven patients developed VTE and 387 died (24-month cumulative risk: 7.5% and 42.1%, respectively). Patients had median TFPI levels at study inclusion of 56.4ng/mL (IQR: 45.7-70.0), with highest levels in tumor types known to have a high risk of VTE (gastroesophageal-, pancreatic and brain-cancer: 62.0ng/mL [IQR: 52.0-75.0]). In multivariable analysis adjusting for age, sex, cancer type and stage, TFPI levels were associated with VTE risk (SHR per doubling: 1.63, 95%CI: 1.03-2.57). When patients with high and intermediate/low VTE risk were analyzed separately, the association remained independently associated in the high risk group only (SHR: 2.63, 95%CI: 1.40-4.94). TFPI levels were independently associated with all-cause mortality (HR: 2.36, 95%CI: 1.85-3.00). In cancer patients increased TFPI levels are associated with VTE risk, specifically in patients with high risk tumor types, and with all-cause mortality.

Thymus alterations and susceptibility to immune checkpoint inhibitor myocarditis

Nat Med. 2023 Oct 26. doi: 10.1038/s41591-023-02591-2. Online ahead of print.

ABSTRACT

Immune checkpoint inhibitors (ICI) have transformed the therapeutic landscape in oncology. However, ICI can induce uncommon life-threatening autoimmune T-cell-mediated myotoxicities, including myocarditis and myositis. The thymus plays a critical role in T cell maturation. Here we demonstrate that thymic alterations are associated with increased incidence and severity of ICI myotoxicities. First, using the international pharmacovigilance database VigiBase, the Assistance Publique Hôpitaux de Paris-Sorbonne University data warehouse (Paris, France) and a meta-analysis of clinical trials, we show that ICI treatment of thymic epithelial tumors (TET, and particularly thymoma) was more frequently associated with ICI myotoxicities than other ICI-treated cancers. Second, in an international ICI myocarditis registry, we established that myocarditis occurred earlier after ICI initiation in patients with TET (including active or prior history of TET) compared to other cancers and was more severe in terms of life-threatening arrythmias and concurrent myositis, leading to respiratory muscle failure and death. Lastly, we show that presence of anti-acetylcholine-receptor antibodies (a biological proxy of thymic-associated autoimmunity) was more prevalent in patients with ICI myocarditis than in ICI-treated control patients. Altogether, our results highlight that thymic alterations are associated with incidence and seriousness of ICI myotoxicities. Clinico-radio-biological workup evaluating the thymus may help in predicting ICI myotoxicities.

Measurement of adherence and health-related quality of life during anticoagulation therapy in cancer-associated venous thromboembolism (VTE): a multicenter quantitative study

Support Care Cancer. 2023 Oct 6;31(10):615. doi: 10.1007/s00520-023-08073-y.

ABSTRACT

PURPOSE: Therapy for cancer-associated venous thromboembolism (VTE) includes long-term anticoagulation, which may have substantial impact on the health-related quality of life (HRQL) of patients. We assessed patient-reported outcomes to characterize the HRQL associated with VTE treatment and to begin to examine those HRQL elements impacting anticoagulation adherence (AA).

METHODS: Participants were adult cancer patients with confirmed symptomatic acute lower extremity deep venous thrombosis. Patients were excluded if there was an indication for anticoagulation other than VTE, ECOG performance status >3, or life expectancy < 3 months. Participants were assessed with a self-reported adherence tool. HRQL was measured with a 6-domain questionnaire using a seven-point Likert scale. Evaluations were performed at 30 days and 3 months after enrollment. For the primary objective, an overall adherence rate was calculated at each time point of evaluation. For the HRQL domains, non-parametric testing was used to compare results between subgroups.

RESULTS: Seventy-four patients were enrolled. AA and HRQL at 30 days and 3 months were assessed in 50 and 36 participants, respectively. At 30 days the AA rate was 90%, and at 3 months it was 83%. In regard to HRQL, patients suffered frequent and moderate-severe distress in the domains of emotional and physical symptoms, sleep disturbance, and limitations to physical activity. An association between emotional or physical distress and AA was observed.

CONCLUSION: Patients with VTE suffer a substantial impairment of their HRQL. Increased emotional distress correlated with better long-term AA. These results can be used to inform additional research aimed at developing novel strategies to improve AA.

Association between baseline blood pressure and the incidence of lenvatinib-induced hypertension in patients with thyroid cancer

Cancer Med. 2023 Oct 30. doi: 10.1002/cam4.6644. Online ahead of print.

ABSTRACT

BACKGROUND: Hypertension is the most frequently occurring adverse event of lenvatinib, recognized relatively early in its course. However, the trend in blood pressure after the initiation of lenvatinib and the outcomes with antihypertensive treatment are unclear. This study aimed to clarify the association between baseline blood pressure and the incidence of lenvatinib-induced hypertension in patients with thyroid cancer.

METHODS: This retrospective study included 65 patients without hypertension at the time of lenvatinib initiation. Patients were divided into two groups: those who developed hypertension grade ≥3 (HTN group) and those who did not develop hypertension grade ≥3 (non-HTN group).

RESULTS: Of the 65 patients, 46 (71%) developed hypertension grade ≥3. In both HTN and non-HTN groups, blood pressure significantly increased the day after lenvatinib initiation. There was no significant difference in the elevated values of both the changes in systolic blood pressure (ΔSBP) and diastolic blood pressure (ΔDBP) between the two groups, with an average increase of 20 mmHg in SBP and 13 mmHg in DBP from baseline. The median (range) time to the onset of hypertension grade ≥3 was 2 days (1-12 days). In the multivariable analysis, patients with normal (SBP 120-129 mmHg and/or DBP 80-84 mmHg) or high-normal baseline blood pressure (SBP 130-139 mmHg and/or DBP 85-89 mmHg) were at higher risk of developing hypertension grade ≥3 than those with optimal baseline blood pressure (SBP <120<80

CONCLUSIONS: Lenvatinib-induced hypertension appears the day after administration, and higher baseline blood pressure is a significant risk factor for developing hypertension grade ≥3. In cases of increased blood pressure with lenvatinib, early initiation of antihypertensives may prevent treatment interruption due to hypertension and maintain the therapeutic intensity of lenvatinib.

Chinese Clinical Trial Registry 13-year data collection and analysis: geographic distribution, financial support, research phase, duration, and disease categories

Front Med (Lausanne). 2023 Oct 12;10:1203346. doi: 10.3389/fmed.2023.1203346. eCollection 2023.

ABSTRACT

OBJECTIVE: To evaluate the current status of trial registration on the Chinese Clinical Trial Registry (ChiCTR).

DESIGN: In this descriptive study, a multi-dimensional grouping analysis was conducted to estimate trends in the annual trial registration, geographical distribution, sources of funding, targeted diseases, and trial subtypes.

SETTING: We have analyzed all clinical trial records (over 30,000) registered on the Chinese Clinical Trial Registry (ChiCTR) from 2007 to 2020 executed in China.

MAIN OUTCOMES AND MEASURES: The main outcome was the baseline characteristics of registered trials. These trials were categorized and analyzed based on geographical distribution, year of implementation, disease type, resource and funding type, trial duration, trial phase, and the type of experimental approach.

RESULTS: From 2008 to 2017, a consistent upward trend in clinical trial registrations was observed, showing an average annual growth rate of 29.2%. The most significant year-on-year (yoy%) growth in registrations occurred in 2014 (62%) and 2018 (68.5%). Public funding represented the predominant source of funding in the Chinese healthcare system. The top five ChiCTR registration sites for all disease types were highly populated urban regions of China, including Shanghai (5,658 trials, 18%), Beijing (5,127 trials, 16%), Guangdong (3,612 trials, 11%), Sichuan (2,448 trials, 8%), and Jiangsu (2,196 trials, 7%). Trials targeting neoplastic diseases accounted for the largest portion of registrations, followed by cardio/cerebrovascular disease (CCVD) and orthopedic diseases-related trials. The largest proportions of registration trial duration were 1-2 years, less than 1 year, and 2-3 years (at 27.36, 26.71, and 22.46%). In the case of the research phase, the top three types of all the registered trials are exploratory research, post-marketing drugs, and clinical trials of new therapeutic technology.

CONCLUSION AND RELEVANCE: Oncological and cardiovascular diseases receive the highest share of national public funding for medical clinical trial-based research in China. Publicly funded trials represent a major segment of the ChiCTR registry, indicating the dominating role of public governance in this health research sector. Furthermore, the growing number of analyzed records reflect the escalation of clinical research activities in China. The tendency to distribute funding resources toward exceedingly populated areas with the highest incidence of oncological and cardiovascular diseases reveals an aim to reduce the dominating disease burden in the urban conglomerates in China.

ABSTRACT

Osimertinib, a third-generation tyrosine kinase inhibitor, is the first-line treatment for metastatic non-small cell lung cancer (NSCLC) with sensitizing epidermal growth factor receptor (EGFR) mutations. It is known to cause drug-induced cardiotoxicity, including QT prolongation syndrome, heart failure, and ventricular arrhythmias, which can lead to sudden death. Once severe arrhythmias occur, it is difficult to continue osimertinib treatment. We report a case of a 66-year-old woman with recurrent NSCLC after concurrent chemoradiotherapy who experienced osimertinib-induced ventricular arrhythmia-causing syncope. The patient was initially treated with concurrent chemoradiotherapy, and genetic testing revealed EGFR exon 19 deletion. Three years following treatment initiation, the primary tumor progressed, and new bone metastases developed. The patient was diagnosed with recurrent NSCLC and was treated with targeted therapy with osimertinib. On the 10th day of osimertinib administration, syncope occurred. Electrocardiography showed polymorphic non-sustained ventricular tachycardia, which was believed to be the cause of syncope. The patient was switched to erlotinib. Two and a half years later, disease progression in the primary lesion was observed. A liquid biopsy revealed an EGFR T790M resistance mutation. Therefore, osimertinib (40 mg) was administered every alternate day. After confirming the absence of palpitations and arrhythmias on electrocardiogram, the osimertinib dosing was increased to 40 mg daily. Thereafter, no further events occurred, and tumor shrinkage was observed. Low-dose osimertinib rechallenge after induced ventricular arrhythmia may be considered an option under close monitoring; however, osimertinib rechallenge must be carefully selected based on the risk-benefit analysis.
