ABSTRACT

BACKGROUND: The importance of D-dimers (DD) assessment in the diagnostic algorithm of venous thromboembolic (VTE) disease is well known. Increase of DD concentration may be also associated with neoplastic disease. Many studies documented that high concentration of DD before solid tumour surgery indicates more advanced disease and poor life expectancy. The prognostic value of the DD concentration variability in the perioperative period, in women undergoing breast cancer surgery, has not been analysed so far. Thus, the aim of the present prospective study was to assess whether the trend of DD concentration changes in the perioperative period may predict cancer recurrence in women undergoing breast cancer surgery.

MATERIALS AND METHODS: 189 consecutive women with histopathological diagnosis of breast cancer (BC) referred for surgical treatment were included. DD concentration was measured twice in each patient: at the time of admission to hospital and at the time of discharge home. Enoxaparin in standard dose of 40 mg daily s. c. was used as primary VTE prophylaxis in all of the patients.

RESULTS: The recurrence of BC, within 1 year observation time, occurred in 13 patients (6.8%), in 11 (5.8%) patients with DD increase after surgery and only in 2 (1.1%) without an increase in DD, P = .0179. Increase in DD concentration after BC surgery was an independent positive predictor of disease relapse (OR 8.600, LCI 1.451, UCI 96.80, P = .0371) together with the lack of postoperative radiotherapy (OR 6.009, LCI 1.305, UCI 31.95, P = .0245), whereas the lack of postoperative chemotherapy predicted no BC relapse (OR .07355, LCI .0056, UCI .58, P = .0245).

CONCLUSIONS: Increase of DD in the early postoperative period may be considered as additional independent predictor of recurrence of BC within 1 year.

Hypoxia-induced exosomes facilitate lung pre-metastatic niche formation in hepatocellular carcinoma through the miR-4508-RFX1-IL17A-p38 MAPK-NF-κB pathway

Int J Biol Sci. 2023 Sep 4;19(15):4744-4762. doi: 10.7150/ijbs.86767. eCollection 2023.

ABSTRACT

Background: Hypoxia plays an important role in the lung metastasis of hepatocellular carcinoma (HCC). However, the process by which hypoxia promotes the formation of a pre-metastatic niche (PMN) and its underlying mechanism remain unclear. Methods: Exosomes derived from normoxic and hypoxic HCC cells were collected to induce fibroblast activation in vitro and PMN formation in vivo. The micro RNA (miR) profiles of the exosomes were sequenced to identify differentially expressed miRNAs. Gain- and loss-of-function analyses were performed to investigate miR-4508 function. Dual-luciferase, western blotting, and real-time reverse transcription-PCR analyses were used to identify the direct targets of miR-4508 and its downstream signaling pathways. To demonstrate the roles of hypoxic tumor-derived exosomes (H-TDEs) and miR-4508 in the lung metastasis of liver cancer, H22 tumor cells were injected through the tail vein of mice. Blood plasma-derived exosomes from patients with HCC who underwent transarterial chemoembolization (TACE) were applied to determine clinical correlations. Results: We demonstrated that H-TDEs activated lung fibroblasts and facilitated PMN formation, thereby promoting lung metastasis in mice. Screening for upregulated exosomal miRNAs revealed that miR-4508 and its target, regulatory factor X1 (RFX1), were involved in H-TDE-induced lung PMN formation. Moreover, miR-4508 was significantly upregulated in plasma exosomes derived from patients with HCC after TACE. We confirmed that the p38 MAPK-NF-κB signaling pathway is involved in RFX1 knockdown-induced fibroblast activation and PMN formation. In addition, IL17A, a downstream target of RFX1, was identified as a link between RFX1 knockdown and p38 MAPK activation in fibroblasts. Conclusion: Hypoxia enhances the release of TDEs enriched with miR-4508, thereby promoting lung PMN formation by targeting the RFX1-IL17A-p38 MAPK-NF-κB pathway. These findings highlight a novel mechanism underlying hypoxia-induced pulmonary metastasis of HCC.

Anti-Inflammatory and Anticancer Effects of Anticoagulant Therapy in Patients with Malignancy

Life (Basel). 2023 Sep 10;13(9):1888. doi: 10.3390/life13091888.

ABSTRACT

Optimizing the anticoagulation therapy is of pivotal importance in patients with a malignant tumor, as venous thromboembolism (VTE) has become the second-leading cause of death in this population. Cancer can highly increase the risk of thrombosis and bleeding. Consequently, the management of cancer-associated VTE is complex. In recent years, translational research has intensified, and several studies have highlighted the role of inflammatory cytokines in cancer growth and progression. Simultaneously, the pleiotropic effects of anticoagulants currently recommended for VTE have emerged. In this review, we describe the anti-inflammatory and anticancer effects of both direct oral anticoagulants (DOACs) and low-molecular-weight heparins (LWMHs).

Major Intraoperative Complications During Minimally Invasive Esophagectomy

Ann Surg Oncol. 2023 Oct 2. doi: 10.1245/s10434-023-14340-3. Online ahead of print.

ABSTRACT

BACKGROUND: Studies have shown minimally invasive esophagectomy (MIE) to be a feasible surgical technique in treating esophageal carcinoma. Postoperative complications have been extensively reviewed, but literature focusing on intraoperative complications is limited. The main objective of this study was to report major intraoperative complications and 90-day mortality during MIE for cancer.

METHODS: Data were collected retrospectively from 10 European esophageal surgery centers. All intention-to-treat, minimally invasive laparoscopic/thoracoscopic esophagectomies with gastric conduit reconstruction for esophageal and GE junction cancers operated on between 2003 and 2019 were reviewed. Major intraoperative complications were defined as loss of conduit, erroneous transection of vascular structures, significant injury to other organs including bowel, heart, liver or lung, splenectomy, or other major complications including intubation injuries, arrhythmia, pulmonary embolism, and myocardial infarction.

RESULTS: Amongst 2862 MIE cases we identified 98 patients with 101 intraoperative complications. Vascular injuries were the most prevalent, 41 during laparoscopy and 19 during thoracoscopy, with injuries to 18 different vessels. There were 24 splenic vascular or capsular injuries, 11 requiring splenectomies. Four losses of conduit due to gastroepiploic artery injury and six bowel injuries were reported. Eight tracheobronchial lesions needed repair, and 11 patients had significant lung parenchyma injuries. There were 2 on-table deaths. Ninety-day mortality was 9.2%.

CONCLUSIONS: This study offers an overview of the range of different intraoperative complications during minimally invasive esophagectomy. Mortality, especially from intrathoracic vascular injuries, appears significant.

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.

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.

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.

ATP protects anti-PD-1/radiation-induced cardiac dysfunction by inhibiting anti-PD-1 exacerbated cardiomyocyte apoptosis, and improving autophagic flux

Heliyon. 2023 Oct 5;9(10):e20660. doi: 10.1016/j.heliyon.2023.e20660. eCollection 2023 Oct.

ABSTRACT

The synergy between radiotherapy and immunotherapy in treating thoracic cancers presents a potent therapeutic advantage, yet it also carries potential risks. The extent and nature of cumulative cardiac toxicity remain uncertain, prompting the need to discern its mechanisms and devise effective mitigation strategies. Radiation alone or in combination with an anti- Programmed cell death protein1 (PD-1) antibody significantly reduced cardiac function in C57BL/6J mice, and this pathologic effect was aggravated by anti-PD-1 (anti-PD-1 + radiation). To examine the cellular mechanism that causes the detrimental effect of anti-PD-1 upon cardiac function after radiation, AC16 human cardiomyocytes were used to study cardiac apoptosis and cardiac autophagy. Radiation-induced cardiomyocyte apoptosis was significantly promoted by anti-PD-1 treatment, while anti-PD-1 combined radiation administration blocked the cardiac autophagic flux. Adenosine 5'-triphosphate (ATP) (a molecule that promotes lysosomal acidification) not only improved autophagic flux in AC16 human cardiomyocytes, but also attenuated apoptosis induced by radiation and anti-PD-1 treatment. Finally, ATP administration in vivo significantly reduced radiation-induced and anti-PD-1-exacerbated cardiac dysfunction. We demonstrated for the first time that anti-PD-1 can aggravate radiation-induced cardiac dysfunction via promoting cardiomyocyte apoptosis without affecting radiation-arrested autophagic flux. ATP enhanced cardiomyocyte autophagic flux and inhibited apoptosis, improving cardiac function in anti-PD-1/radiation combination-treated animals.

Complications in patients with transfusion dependent thalassemia: A descriptive cross-sectional study

Health Sci Rep. 2023 Oct 11;6(10):e1624. doi: 10.1002/hsr2.1624. eCollection 2023 Oct.

ABSTRACT

BACKGROUND AND AIMS: One of the most common hemoglobinopathies globally related to blood transfusion and iron overload in the body is thalassemia syndrome. Increasing ferritin levels can cause severe damage to the patient's body organs. This study aims to evaluate the complications of iron overload on vital body organs in patients with transfusion-dependent beta-thalassemia.

METHODS: This descriptive cross-sectional study was performed in Iran University of Medical Sciences Hospitals on patients with a beta-thalassemia major with frequent blood transfusions. To evaluate the effect of iron overload on vital body organs, hematologic and blood analysis, echocardiography with measurement of pulmonary artery pressure (PAP) and ejection fraction (EF) tests, bone densitometry, and audiometric tests were performed for all patients.

RESULTS: Of the 1010 patients participating in this study, 497 (49%) were males, 513 were (51%) females aged 5-74 years, and the majority of participants (85%) were over 20 years old. This study demonstrated that increasing ferritin levels had no notable correlation with sex, cholesterol, low-density lipoprotein, parathyroid hormone, T4, and aspartate aminotransferase. However, elevating ferritin levels had significant correlations with increasing triglyceride, phosphorus, thyroid stimulating hormone, alkaline phosphatase, alanine transaminase, and PAP levels, age, hearing disorders, splenectomy, osteoporosis, and decreasing high-density lipoprotein, body mass index, calcium, and EF levels.

CONCLUSION: Improvement in beta-thalassemia patients' survival and quality of life can be due to multidisciplinary care in a comprehensive unit through regular follow-up and early complication detection.

CDK4/6 inhibitors: basics, pros, and major cons in breast cancer treatment with specific regard to cardiotoxicity - a narrative review

Ther Adv Med Oncol. 2023 Oct 11;15:17588359231205848. doi: 10.1177/17588359231205848. eCollection 2023.

ABSTRACT

Breast cancer is characterized by the uncontrolled proliferation of breast cells, with a high incidence reported in 2020 to have affected over 2 million women. In recent years, the conventional methods of treating breast cancer have involved radiotherapy and chemotherapy. However, the emergence of CDK4/6 inhibitors has shown potential as a promising cancer therapy. Cyclin-dependent kinases (CDK) inhibitors are a class of molecules that impede the formation of an active kinase complex, thereby hindering its activity and consequently halting the progression of the cell cycle. It was discovered that they have a significant impact on impeding the progression of the cancer. This is evident with the Food and Drug Administration's approval of drugs such as palbociclib, ribociclib, and abemaciclib for hormone receptor-positive metastatic breast cancer in combination with specific endocrine therapies. In spite of enormous success in breast cancer treatment, certain obstacles have emerged, such as therapy resistance, side effects, and most of all, cardiotoxicity. Some of these drawbacks have been successfully overcome by dosage reduction, different combinations of the drugs, and the assessment of each patient's condition and suitability prior to treatment. Yet other drawbacks still require tenacious research, especially certain cases of cardiotoxicities. This article delves into the biological mechanisms of CDK4/6 in the cell cycle and cancer, as well as the clinical advantages and most common adverse events (AEs) associated with CDK4/6 inhibitors. The primary objective of this review is to provide a comprehensive analysis of cardiotoxic AEs and elucidate the underlying pathophysiological mechanisms responsible for the cardiotoxicity of CDK4/6 inhibitors.

Social disparities in cardiovascular mortality of patients with cancer in the USA between 1999 and 2019

Int J Cardiol Cardiovasc Risk Prev. 2023 Oct 3;19:200218. doi: 10.1016/j.ijcrp.2023.200218. eCollection 2023 Dec.

ABSTRACT

BACKGROUND: Temporal trends of the impact of social determinants on cardiovascular outcomes of cancer patients has not been previously studied.

OBJECTIVES: This study examined social disparities in cardiovascular mortality of people with and without cancer in the US population between 1999 and 2019.

METHODS: Primary cardiovascular deaths were identified from the Multiple Cause of Death database and grouped by cancer status. The cancer cohort was subcategorized into breast, lung, prostate, colorectal, and haematological. The number of cardiovascular deaths, crude cardiovascular mortality rate, cardiovascular age-adjusted mortality rate (AAMR), and percentage change in cardiovascular AAMR were calculated by cancer status and cancer type, and stratified by sex, race, ethnicity, and urban-rural setting.

RESULTS: 17.9 million cardiovascular deaths were analysed. Of these, 572,222 occurred in patients with a record of cancer. The cancer cohort were older and included more men and White racial groups. Regardless of cancer status, cardiovascular AAMR was higher in men, rural settings, and Black or African American races. Cardiovascular AAMR declined over time, with greater reduction in those with cancer (-51.6% vs -38.3%); the greatest reductions were in colorectal (-68.4%), prostate (-60.0%), and breast (-58.8%) cancers. Sex, race, and ethnic disparities reduced over time, with greater narrowing in the cancer cohort. There was increase in urban-rural disparities, which appeared greater in those with cancer.

CONCLUSIONS: While most social disparities narrowed over time, urban-rural disparities widened, with greater increase in those with cancer. Healthcare plans should incorporate strategies for reduction of health inequality equitable access to cardio-oncology services.

An online home-based exercise program improves autonomic dysfunction in breast cancer survivors

Front Physiol. 2023 Sep 29;14:1256644. doi: 10.3389/fphys.2023.1256644. eCollection 2023.

ABSTRACT

Introduction: Exercise interventions for breast cancer survivors have proved their potential to improve clinical, physical, and psychosocial outcomes. However, limited studies have explored exercise effects on autonomic dysfunction and the measurement of exercise tolerance and progression through daily heart rate variability (HRV). Purpose: To analyze the effects of a 16-wk exercise intervention on the autonomic modulation of breast cancer survivors, as well as to examine the evolution of daily measured HRV and its interaction with exercise sessions in this population. Methods: A total of 29 patients who had undergone chemotherapy and radiotherapy were randomly assigned to the exercise group or to the control group. The exercise intervention was delivered remotely through online meetings and consisted of supervised training resistance and cardiovascular exercise 3 times per week. During the intervention all patients measured their HRV daily obtaining the napierian logarithm of the root mean square of successive differences between normal heartbeats (lnrMSSD) and the napierian logarithm of the standard deviation of the interbeat interval of normal sinus beats (lnSDNN) values at four moments: day 0 (the morning of the training sessions), 24, 48, and 72 h after exercise. Results: The results revealed a significant interaction between group and months during the intervention period for lnrMSSD and lnSDNN (p < 0.001). Additionally, there were significant differences in lnSDNN recovery time between months (p < 0.05), while differences in lnrMSSD become apparent only 24 h after exercise (p = 0.019). The control group experienced a significant decrease in both variables monthly (p < 0.05) while exercise group experienced a significant increment (p < 0.05). Conclusion: HRV is daily affected by exercise training sessions in cancer patients. Although results strongly support the role of exercise as a post-chemotherapy and radiotherapy rehabilitation strategy for breast cancer survivors to improve autonomic imbalance, further research is necessary to validate these initial findings.

Clinical outcomes of takotsubo syndrome in patients with cancer: a systematic review and meta-analysis

Front Cardiovasc Med. 2023 Sep 29;10:1244808. doi: 10.3389/fcvm.2023.1244808. eCollection 2023.

ABSTRACT

BACKGROUND: Recent studies suggested a relationship between Takotsubo syndrome (TTS) and malignancy. However, clinical outcomes of TTS associated with cancer have not been assessed completely. This study was aimed to investigate the outcomes of patients with TTS and cancer.

METHODS: We performed a systematic review and meta-analysis to evaluate the clinical outcomes of TTS in patients with and without malignancy. We systematically reviewed and analyzed 14 studies (189,210 patients) published in PubMed and Cochrane Library databases until December 2022. The primary outcome was all-cause mortality at the longest follow-up.

RESULTS: The prevalence of current or previous malignancy in patients with TTS was 8.7% (16,461 patients). Patients with TTS and malignancy demonstrated a higher risk of mortality at the longest follow-up than those with TTS alone (odds ratio [OR], 2.41; 95% confidence interval [CI]; 1.95-2.98; P < 0.001). Moreover, cancer was significantly associated with an increased risk of in-hospital or 30-day mortality (OR 2.36; 95% CI, 1.67-3.33; P < 0.001), shock (OR 1.42; 95% CI, 1.30-1.55; P < 0.001), mechanical respiratory support (OR 1.68; 95% CI, 1.59-1.77; P < 0.001), arrhythmia (OR 1.27; 95% CI, 1.21-1.34; P < 0.001), and major adverse cardiac events (OR 1.69; 95% CI, 1.18-2.442; P < 0.001).

CONCLUSIONS: This study revealed significant associations between previous or active cancer and an increased risk of all-cause mortality and in-hospital adverse events in patients with TTS.

Pyothorax and Constrictive Pericarditis after Chemoradiotherapy for Esophageal Cancer: A Case Report

Intern Med. 2023 Oct 13. doi: 10.2169/internalmedicine.2502-23. Online ahead of print.

ABSTRACT

A 75-year-old man underwent chemoradiotherapy for advanced esophageal cancer. After nine years, he was hospitalized for left pyothorax. Consequently, the patient underwent drainage and window opening surgery. He experienced cardiopulmonary arrest but was resuscitated. Based on cardiac catheterization data, the patient was diagnosed with constrictive pericarditis. Unfortunately, extracorporeal circulation did not improve his condition, and he ultimately died. An autopsy revealed adhesion between the pericardium and pleura, especially the pericardium in contact with the left thoracic cavity, which was markedly thickened. This suggests that constrictive pericarditis, a latent complication of chemoradiotherapy, is aggravated by pyothorax.

Association of chronic kidney disease with cardiovascular disease in cancer patients: a cross-sectional study

Cardiorenal Med. 2023 Oct 14. doi: 10.1159/000534182. Online ahead of print.

ABSTRACT

INTRODUCTION: Due to the cardiotoxicity of cancer treatment and traditional risk factors for cardiovascular disease (CVD) such as obesity, diabetes, dyslipidemia, and hypertension, cancer patients are at higher risk of developing CVD. However, limited research exists on the correlation between chronic kidney disease (CKD) and CVD risk in cancer patients.

METHODS: This cross-sectional study selected cancer patients aged ≥20 years from the National Health and Nutrition Examination Survey (NHANES) conducted from 2015 to 2020. Multivariable logistic regression was used to assess the association between CKD and CVD in cancer patients. Additionally, subgroup analyses were conducted to investigate the association among different groups of cancer patients.

RESULTS: We included 1700 adult cancer patients (52.53% were female). After multivariable adjustment for covariates including traditional CVD factors, CKD was significantly associated with CVD, with an odds ratio (95% confidence interval) and P-value of 1.61(1.18,2.19) and 0.004. Subgroup analyses after multivariable adjustment showed a significant correlation between CKD and increased CVD risk in the following populations: age ≥60 years, males, White ethnicity, and individuals with or without traditional CVD factors (obesity, diabetes, dyslipidemia, and hypertension).

CONCLUSIONS: CKD remains a significant factor in the higher risk of CVD among adult cancer patients in the United States, even after adjustment for traditional CVD risk factors. Therefore, to reduce the risk of CVD in cancer patients, it is important to treat CKD as a non-traditional risk factor for CVD and actively manage it.
