ABSTRACT

BACKGROUND: Benign airway stenosis (BAS) represents a significant burden on patients, providers, and healthcare systems. Spray cryotherapy (SCT) has been proposed as an adjunctive treatment to reduce BAS recurrence. We sought to examine safety and practice variations of the latest SCT system when used for BAS.

METHODS: We conducted a retrospective multicenter cohort study in seven academic institutions within the Interventional Pulmonary Outcomes Group. All patients who underwent at least one SCT session with a diagnosis of BAS at the time of procedure at these institutions were included. Demographics, procedure characteristics, and adverse events were captured through each center's procedural database and electronic health record.

RESULTS: A total of 102 patients underwent 165 procedures involving SCT from 2013 to 2022. The most frequent etiology of BAS was iatrogenic (n = 36, 35%). In most cases, SCT was used prior to other standard BAS interventions (n = 125; 75%). The most frequent SCT actuation time per cycle was five seconds. Pneumothorax complicated four procedures, requiring tube thoracostomy in two. Significant post-SCT hypoxemia was noted in one case, with recovery by case conclusion and no long-term effects. There were no instances of air embolism, hemodynamic compromise, or procedural or in-hospital mortality.

CONCLUSION: SCT as an adjunctive treatment for BAS was associated with a low rate of complications in this retrospective multicenter cohort study. SCT-related procedural aspects varied widely in examined cases, including actuation duration, number of actuations, and timing of actuations relative to other interventions.

Safety Profile and Effectiveness of Rivaroxaban for Patients With Venous Thromboembolism in Japan　- Results From Post-Marketing Surveillance (XASSENT)

Circ J. 2023 May 27. doi: 10.1253/circj.CJ-23-0104. Online ahead of print.

ABSTRACT

BACKGROUND: The incidence of venous thromboembolism (VTE; pulmonary embolism [PE] and/or deep vein thrombosis [DVT]) in Japan is increasing, but relatively small numbers of patients from Japan have been included in studies investigating rivaroxaban (a direct factor Xa inhibitor) for the treatment of VTE and preventing its recurrence.Methods and Results: An open-label, prospective, observational study (XASSENT [NCT02558465]) investigated the safety profile and effectiveness of rivaroxaban for ≤2 years in the treatment of VTE and prevention of its recurrence in Japanese clinical practice. Primary outcomes were major bleeding and symptomatic recurrent VTE. Statistical analyses were exploratory and descriptive. Overall, 2,540 patients were enrolled (safety analysis population [SAP], n=2,387; effectiveness analysis population [EAP], n=2,386). In the SAP, >80% of patients received the approved rivaroxaban dose, the mean (standard deviation) age was 66.6 (15.0) years, ≈74% were >50 kg, and 43% had a creatinine clearance ≥80 mL/min. PE+DVT, PE only, and DVT only were reported in 42%, 8%, and 50% of patients, respectively, and active cancer in 17% of patients. Major bleeding was reported in 69 patients (2.89%; 3.60%/patient-year; SAP) and symptomatic PE/DVT recurrence in 26 patients (1.09%; 1.36%/patient-year; EAP) during the treatment period.

CONCLUSIONS: XASSENT provided information on the expected proportions of bleeding and VTE recurrence during rivaroxaban treatment in Japanese clinical practice; no new concerns of safety or effectiveness were found.

Hypercoagulability State Combined with Post-Treatment Hypofibrinolysis in Invasive Breast Cancer: A Seven-Year Follow-Up Evaluating Disease-Free and Overall Survival

Life (Basel). 2023 Apr 28;13(5):1106. doi: 10.3390/life13051106.

ABSTRACT

(1) Background: Cancer treatment, including chemotherapy, endocrine therapy, targeted therapy and radiotherapy, has been identified as an important independent risk factor for venous thromboembolism in cancer patients. The aim of the study was to evaluate the effect of adjuvant therapy on the coagulation and fibrinolysis components in invasive breast cancer. (2) Methods: Tissue factor pathway inhibitor (TFPI), tissue factor (TF), tissue plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1) antigen (concentration) and TFPI and TF activities were examined in the blood samples of 60 breast cancer patients treated by adjuvant chemotherapy, endocrine therapy, radiotherapy and immunotherapy. Blood samples were taken 24 h before primary surgery and 8 months after tumour removal surgery. (3) Results: Adjuvant therapy administrated to breast cancer patients significantly increased the concentration of plasma TF, the PAI-1 antigen and also the activity of TFPI and TF, but significantly decreased the level of the t-PA antigen. Combined chemotherapy and endocrine therapy, but not monotherapy, has an important effect on haemostatic biomarker levels. (4) Conclusions: Breast cancer patients receiving adjuvant therapy have an elevated risk of developing a hypercoagulability and hypofibrinolysis state leading to venous thromboembolism.

Phase 1 study of GSK3368715, a type I PRMT inhibitor, in patients with advanced solid tumors

Br J Cancer. 2023 May 26. doi: 10.1038/s41416-023-02276-0. Online ahead of print.

ABSTRACT

BACKGROUND: GSK3368715, a first-in-class, reversible inhibitor of type I protein methyltransferases (PRMTs) demonstrated anticancer activity in preclinical studies. This Phase 1 study (NCT03666988) evaluated safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of GSK3368715 in adults with advanced-stage solid tumors.

METHODS: In part 1, escalating doses of oral once-daily GSK3368715 (50, 100, and 200 mg) were evaluated. Enrollment was paused at 200 mg following a higher-than-expected incidence of thromboembolic events (TEEs) among the first 19 participants, resuming under a protocol amendment starting at 100 mg. Part 2 (to evaluate preliminary efficacy) was not initiated.

RESULTS: Dose-limiting toxicities were reported in 3/12 (25%) patients at 200 mg. Nine of 31 (29%) patients across dose groups experienced 12 TEEs (8 grade 3 events and 1 grade 5 pulmonary embolism). Best response achieved was stable disease, occurring in 9/31 (29%) patients. Following single and repeat dosing, GSK3368715 maximum plasma concentration was reached within 1 h post dosing. Target engagement was observed in the blood, but was modest and variable in tumor biopsies at 100 mg.

CONCLUSION: Based on higher-than-expected incidence of TEEs, limited target engagement at lower doses, and lack of observed clinical efficacy, a risk/benefit analysis led to early study termination.

TRIAL REGISTRATION NUMBER: NCT03666988.

The Role of EGFR Amplification in Deep Venous Thrombosis Occurrence in IDH Wild-Type Glioblastoma

Curr Oncol. 2023 May 12;30(5):4946-4956. doi: 10.3390/curroncol30050373.

ABSTRACT

Introduction:Glioblastoma (GBM) patients have a 20-30 incidence of venous thromboembolic events. EGFR is a widely used prognostic marker for many cancers. Recent lung cancer studies have described relationships between EGFR amplification and an increased incidence of thromboembolic complications. We aim to explore this relationship in glioblastoma patients. Methods: Two hundred ninety-three consecutive patients with IDH wild-type GBM were included in the analysis. The amplification status of EGFR was measured using fluorescence in situ hybridization (FISH). Centromere 7 (CEP7) expression was recorded to calculate the EGFR-to-CEP7 ratio. All data were collected retrospectively through chart review. Molecular data were obtained through the surgical pathology report at the time of biopsy. Results:There were 112 subjects who were EGFR-amplified (38.2%) and 181 who were non-amplified (61.8%). EGFR amplification status was not significantly correlated with VTE risk overall (p = 0.2001). There was no statistically significant association between VTE and EGFR status after controlling for Bevacizumab therapy (p = 0.1626). EGFR non-amplified status was associated with an increased VTE risk in subjects greater than 60 years of age (p = 0.048). Conclusions:There was no significant difference in occurrence of VTE in patients with glioblastoma, regardless of EGFR amplification status. Patients older than 60 years of age with EGFR amplification experienced a lower rate of VTE, contrary to some reports on non-small-cell lung cancer linking EGFR amplification to VTE risk.

Preoperative Venous Thromboembolism Screening and Postoperative Selective Anticoagulant Therapy Effectively Prevents Postoperative Symptomatic Venous Thromboembolism in Gynecological Malignancies: A 15-Year, Single-Center Study

Clin Appl Thromb Hemost. 2023 Jan-Dec;29:10760296231178300. doi: 10.1177/10760296231178300.

ABSTRACT

The aim of this study was to determine which type of prophylaxis was effective for postoperative symptomatic venous thromboembolism (VTE) in patients with gynecological malignancies. A total of 1756 consecutive patients undergoing laparotomy as first-line treatment were included. In Period 1 (2004-2009), low-molecular weight heparin (LMWH) was not available for postoperative VTE prophylaxis, but available in after Period 2 (2009-2013). In Period 3 (2013-2020), patients with pretreatment VTE could switch from LMWH to direct oral anticoagulant (DOAC) as of 2015. Preoperative VTE was screened by measuring D-dimer, followed by venous ultrasound imaging, and computed tomography and/or perfusion lung scintigraphy. Postoperative symptomatic VTE occurred with an incidence of 2.8% by the measures without prophylactic LMWH administration in Period 1. The incidence of postoperative symptomatic VTE was 0.6% in Period 2 and 0.3% in Period 3, being significantly reduced compared with Period 1 (P < .01 and < .0001). The incidences were not significantly different between Periods 2 and 3, but no patient switching to DOAC in Period 3 (n = 79) developed symptomatic VTE. Our preoperative VTE screening and postoperative selective LMWH administration were significantly preventive against postoperative symptomatic VTE.

Cardiac Metastatic Tumors: Current Knowledge

Am J Clin Oncol. 2023 May 26. doi: 10.1097/COC.0000000000001013. Online ahead of print.

ABSTRACT

Cardiac tumors are a heterogeneous group of pathologic masses of the heart that contain primary tumors-benign or malignant, and secondary tumors. Metastases are significantly more frequent, mostly originating from lung, breast, gastrointestinal tract, or ovary carcinomas. Secondary cardiac tumors may be asymptomatic or may cause cardiovascular, systemic, or embolic symptoms. The study is a summary of the available knowledge on cancerous metastatic lesions of the heart. Pleural mesothelioma (48.4%), adenocarcinoma (19.5%), or squamous cell carcinoma (18.2%) of lung, breast carcinoma (15.5%), ovarian carcinoma (10.3%), and bronchoalveolar carcinomas (9.8%) are cited as the most common origin of secondary heart tumors. Masses can spread by direct tumor invasion, by lymphatic vessels, veins, or arteries. Patients with cancer and nonspecific cardiovascular symptoms should be particularly vigilant, and the possibility of metastasis in an unusual location such as the myocardium should be considered in the diagnosis. Diagnostic methods include echocardiography, cardiac magnetic resonance, computed tomography, positron emission tomography, and histologic evaluation. Treatment of choice is managing primary carcinoma, due to the poor outcomes of surgical methods.

Venous thromboembolism secondary to hospitalization for COVID-19: patient management and long-term outcomes

Res Pract Thromb Haemost. 2023 May;7(4):100167. doi: 10.1016/j.rpth.2023.100167. Epub 2023 Apr 26.

ABSTRACT

BACKGROUND: Venous thromboembolism (VTE) is a complication of COVID-19 in hospitalized patients. Little information is available on long-term outcomes of VTE in this population.

OBJECTIVES: We aimed to compare the characteristics, management strategies, and long-term clinical outcomes between patients with COVID-19-associated VTE and patients with VTE provoked by hospitalization for other acute medical illnesses.

METHODS: This is an observational cohort study, with a prospective cohort of 278 patients with COVID-19-associated VTE enrolled between 2020 and 2021 and a comparison cohort of 300 patients without COVID-19 enrolled in the ongoing START2-Register between 2018 and 2020. Exclusion criteria included age <18<3

RESULTS: Patients with VTE secondary to COVID-19 had more frequent pulmonary embolism without deep vein thrombosis than controls (83.1% vs 46.2%, P<.001),P<.001),P<.001).P= 0.9) and the proportion of patients who discontinued anticoagulation (78.0% and 75.0%, P= 0.4) were similar between the 2 groups. Thrombotic event rates after discontinuation were 1.5 and 2.6 per 100 patient-years, respectively (P = 0.4).

CONCLUSION: The risk of recurrent thrombotic events in patients with COVID-19-associated VTE is low and similar to the risk observed in patients with VTE secondary to hospitalization for other medical diseases.

Pulmonary embolism complicated by tamponade revealing metastatic lung cancer in a woman pregnant with twin: about a case report

Ann Med Surg (Lond). 2023 Apr 7;85(5):1966-1970. doi: 10.1097/MS9.0000000000000516. eCollection 2023 May.

ABSTRACT

Lung cancer can be revealed by thromboembolic complications. Its association with pregnancy is becoming more frequent due to the increasing number of smoking women. The care of a pregnant woman with cancer is quite delicate because it requires finding a balance between the treatment of the mother and the potential foetal risk.

CASE PRESENTATION: The authors report the case of a 38-year-old patient, with a twin pregnancy of 16 weeks, complicated by proximal and distal peripheral venous thrombosis of the left lower limb under low molecular weight heparin therapy at a curative dose. A week later, the patient presented to the emergency room with respiratory distress associated with chest pain and low-abundance metrorrhagia. The obstetrical ultrasound performed confirmed the vitality of only one of the two foetuses. The transthoracic ultrasound objectified a very abundant pericardial effusion producing a tamponade, which was drained percutaneously and whose cytological study revealed a liquid rich in tumour cells. After the unfortunate death of the second twin and an endouterine evacuation, a chest computed tomography angiogram demonstrated a bilateral proximal pulmonary embolism associated with bilateral moderate pulmonary effusion as well as multiple thrombosis and secondary aspect liver lesions with a suspicious parenchymal lymph node of the upper lung lobe. A liver biopsy concluded to a secondary hepatic localization of a moderately differentiated adenocarcinoma whose immunohistochemical complement revealed a pulmonary origin. A multidisciplinary consultation meeting leaned towards treatment with neoadjuvant chemotherapy. The patient died 7 months later.

DISCUSSION: Venous thromboembolic disease is more common in pregnant women. Delayed diagnosis is common in these cases, resulting in a high rate of locally advanced or metastatic disease. Since the treatment of pregnancy-associated cancer does not rely on a standardized approach, the decision on how to proceed must be made by a multidisciplinary team.

CONCLUSION: The cornerstone of management remains to find the balance between treating the mother as well as possible while preventing the foetus from the possible harm of cytotoxic drugs frequently used to treat lung cancer. Because of the delayed diagnosis, the maternal prognosis often remains poor.
