ABSTRACT

Patients with sickle cell disease (SCD) are predisposed to a hypercoagulable state due to alterations in the coagulation system. Despite concern for the development of venous thromboembolism (VTE) in this population, there are no standardized guidelines for routine thromboprophylaxis. The objective of this study was to assess thromboprophylaxis practices of adult and pediatric treaters of SCD before and during the coronavirus disease of 2019 (COVID-19) pandemic. A cross-sectional electronic survey was distributed to pediatric and adult hematology oncology practitioners through seven SCD-specific interest groups between May 29, 2020, and July 13, 2020. Of 93 total responses, 14% (N = 13) reported they only treat patients more than 21 years old; 38.7% (N = 36) only treat patients 0-21 years old and 47.3% (N = 44) reported they treat both. Our study showed that before the COVID-19 pandemic, 96% of adult practitioners would recommend pharmacologic thromboprophylaxis, mechanical thromboprophylaxis or both for hospitalized adults with thromboprophylaxis, but only 76% of pediatric treaters would recommend any thromboprophylaxis in hospitalized children (P < 0.0001), with 24% of pediatric treaters choosing no thromboprophylaxis at all. During the COVID-19 pandemic, pharmacologic thromboprophylaxis specifically was recommended for adults by 94% of treaters and for pediatric patients by 76% of treaters. These findings suggest that despite the lack of evidence-based thromboprophylaxis guidelines in adults and children with thromboprophylaxis, subspecialty treaters routinely provide pharmacologic thromboprophylaxis in their adult patients and will modify their practice in pediatric patients who are considered at a high risk for VTE.

Reverse cardio-oncology: A budding concept

Indian Heart J. 2023 Sep 27:S0019-4832(23)00163-3. doi: 10.1016/j.ihj.2023.09.004. Online ahead of print.

ABSTRACT

Having established the significance of cardiovascular side-effects of anti-neoplastic drugs, present day cardio-oncology has forayed into newer territories buoyed by research into the multiple connections that exist between cardiovascular disease and cancer. An emerging concept of reverse cardio-oncology focuses on the heightened risk of cancer in patients with cardiovascular disease. Common mechanistics of cancer and heart failure (HF) like chronic inflammation and clonal haematopoesis as well as common predisposing factors like obesity and diabetes underline the relation between both cardiovascular disease and various cancers.This review discusses the potential magnitude of the problem, the underlying pathophysiological mechanisms and classification of this novel subject.

Early Echocardiography and ECG Changes Following Radiotherapy in Patients with Stage II-III HER2-Positive Breast Cancer Treated with Anthracycline-Based Chemotherapy with or without Trastuzumab-Based Therapy

Med Sci Monit. 2023 Sep 20;29:e941754. doi: 10.12659/MSM.941754.

ABSTRACT

BACKGROUND Cardiotoxicity from radiotherapy and anti-cancer therapies have been reported in patients with breast cancer. This study aimed to investigate the early echocardiography and ECG changes following radiotherapy in 68 patients ages 30-78 years with stages II-III HER2-positive breast cancer treated with anthracycline-based chemotherapy with or without trastuzumab-based therapy from 2015 to 2021. MATERIAL AND METHODS We analyzed data of 68 breast cancer patients aged 30-78 years, predominantly in AJCC stages II-III (61) and HER2-positive (58), treated and monitored from 2015 to 2021. Cardiac function was assessed using echo- and electrocardiography. We employed univariate logistic models to gauge associations between pre-existing cardiac conditions, treatment modalities, and changes in cardiac function. RESULTS A decrease in the left ventricle ejection fraction (EF) by >5% was associated with heart doses >49.3 Gy and with maximum and average doses to the left anterior descending artery (LAD) exceeding 46.9 Gy and 32.7 Gy, respectively. An EF drop of ≥10% was correlated with anti-HER2 therapy, pre-existing ECG changes, and the onset of conditions in the left ventricle, major vessels, and valves. Conditions were exacerbated in patients with prior echocardiographic abnormalities, while some emerged concurrent with the EF decline. CONCLUSIONS This research emphasizes the importance of personalized heart monitoring and care for breast cancer patients undergoing multimodal therapies. Significant and potentially irreversible EF declines can result from radiation and anti-HER2 treatments.

Venous thromboembolism and risk factors for deep vein thrombosis in patients with pancreatic cancer undergoing chemotherapy

Nihon Shokakibyo Gakkai Zasshi. 2023;120(9):755-763. doi: 10.11405/nisshoshi.120.755.

ABSTRACT

Among various types of cancers, pancreatic cancer is known to be prone to venous thromboembolism (VTE). We investigated the complication rate of VTE and risk factors for deep vein thrombosis (DVT) in patients with pancreatic cancer undergoing chemotherapy. We retrospectively analyzed the data of 51 patients with pancreatic cancer who had undergone chemotherapy at our hospital from January 2016 to March 2021, had their D-dimer levels measured at the initial visit, and had undergone venous ultrasonography if D-dimer levels were elevated. At the initial visit, the complication rate of VTE was 35.3% (18/51 patients). Multivariate analysis revealed that the risk factors for DVT were primary tumors in the pancreas's body and tail and elevated D-dimer levels. Patients with DVT tended to have shorter overall survival than those without (218 vs 523 days). Patients with pancreatic cancer frequently develop VTE and should be aggressively screened for thrombosis, particularly in those with primary tumors in the pancreas's body and tail and elevated D-dimer levels.
