BACKGROUND: Real word data on the efficacy and safety of long-term use of tinzaparin for the treatment of cancer-associated thrombosis (CAT) are scarce. METHODS: We performed a post-hoc analysis of all cancer patients included in the prospective multicenter observational TROPIQUE study who received long-term treatment with tinzaparin for a first venous thromboembolism (VTE) event. We evaluated the patterns of anticoagulant prescription, the adherence to clinical practice guidelines (CPGs) for the treatment of CAT, and the clinical outcomes within a 6-month follow-up...

Pulmonary tumor thrombotic microangiopathy (PTTM) is a fatal disease associated with malignant tumors that progresses to pulmonary hypertension. Gastric cancer is the most common cause, followed by breast cancer and lung cancer, whereas PTTM due to thyroid cancer has not been reported. In addition to pulmonary obstruction by tumor embolism, tumor cells stimulate endothelial cells to release angiogenetic factors, which induce remodeling of pulmonary arteries and veins and lead to lymphatic obstruction. There is limited information on the relationship between thrombus and PTTM...

Patients with metastatic breast cancer are at high risk for developing vertebral compression fractures due to underlying bone metastases and bone density loss. Vertebral augmentation techniques including percutaneous vertebroplasty and percutaneous balloon kyphoplasty are techniques used to stabilize compression fractures and improve pain. However, rare complications from these interventions have been observed, including spinal cord compression, nerve root compression, venous cement embolism, and pulmonary cement embolism...

INTRODUCTION: Etiologies of acute respiratory failure in breast cancer patients are diverse (acute respiratory distress syndrome, acute interstitial pneumonia, pulmonary fibrosis, radiation pneumonitis, malignant infiltration). Pulmonary tumor embolism microangiopathy (PTEM) is a rare complication of advanced cancer that often presents as respiratory failure, pulmonary hypertension, right heart failure, and sudden death. Breast cancer is the most common primary cause of PTEM. It takes an aggressive course and presents with a challenge to diagnose and eventually manage...

Cancer-associated thrombosis (CAT) is an important cause of morbidity and mortality for patients with malignancy and varies by primary cancer type, stage, and therapy. We aimed to characterize the incidence, risk factors, temporal trends, and the effect on mortality of CAT. The California Cancer Registry was linked to the statewide hospitalization database to identify individuals with the 13 most common malignancies diagnosed between 2005 and 2017 and determine the 6- and 12-month cumulative incidence of CAT by venous thromboembolism (VTE) location, tumor type, and stage after adjusting for competing risk of death...

BACKGROUND: Patients with cancer are more likely to develop nonvalvular atrial fibrillation (NVAF). Currently there are no definitive clinical trials or treatment guidelines for NVAF patients with concurrent cancer. OBJECTIVES: This subgroup analysis of the ARISTOPHANES study compared the risk of stroke/systemic embolism (stroke/SE) and major bleeding (MB) among NVAF patients with active cancer who were prescribed non-vitamin K antagonist oral anticoagulants (NOACs) or warfarin...

Background Bevacizumab, a humanized monoclonal antibody, known to block the binding of all known vascular endothelial growth factor-A isomers to their receptors, is used in solid cancers, especially in advanced settings where its role is proven to be stronger than localized stages. Furthermore, various studies have suggested that adding bevacizumab to first-line standard therapy in advanced solid cancers, such as colorectal cancer, lung cancer, ovarian cancer, renal cancer, and breast cancer, significantly prolongs progression-free survival, overall survival, and response rates...

Efficacy and safety of anticoagulant treatment for venous thromboembolism (VTE) may vary in patients with different cancer sites. We evaluated the rates of VTE recurrence and major bleeding and the relative efficacy and safety of 6-month treatment with oral apixaban or subcutaneous dalteparin in patients with different cancer sites randomized in the Caravaggio study. Primary cancer was located at gastrointestinal sites in 375 patients (32.5%), lung in 200 (17.3%), breast in 155 (13.4%), genitourinary sites in 139 (12%), gynecological sites in 119 (10...

BACKGROUND: There remains uncertainty about the impact of menopausal hormone therapy (MHT) on women's health. A systematic, comprehensive assessment of the effects on multiple outcomes is lacking. We conducted an umbrella review to comprehensively summarize evidence on the benefits and harms of MHT across diverse health outcomes. METHODS AND FINDINGS: We searched MEDLINE, EMBASE, and 10 other databases from inception to November 26, 2017, updated on December 17, 2020, to identify systematic reviews or meta-analyses of randomized controlled trials (RCTs) and observational studies investigating effects of MHT, including estrogen-alone therapy (ET) and estrogen plus progestin therapy (EPT), in perimenopausal or postmenopausal women in all countries and settings...

BACKGROUND: Cancer patients are increasingly prescribed direct oral anticoagulants (DOACs) and targeted anticancer therapies, but limited data are available on the outcomes during concurrent use. OBJECTIVES: We conducted an international registry through the Scientific and Standardization Committee of the ISTH to evaluate the characteristics, bleeding, and thrombotic outcomes in patients receiving concurrent DOACs and targeted anticancer therapies. PATIENTS/METHODS: Patients receiving concurrent DOACs for venous thromboembolism (VTE) or atrial fibrillation and selected targeted anticancer therapies were followed for 6 months after the start of concurrent use...

INTRODUCTION: Treatment of Venous thromboembolism (VTE) in cancer patients is challenging due to higher risk of VTE recurrence or bleeding under anticoagulants. We assessed the effectiveness of a dedicated "Allo-Thrombosis Cancer" multidisciplinary care program (AlloTC-MCP) that incorporated individualized care, regular follow-ups, telephone counselling, and a patient education program. METHODS AND MATERIALS: From September 2017 to October 2019, 100 consecutive cancer patients with new VTE onset were enrolled in this observational single-center prospective pilot study and received standard (control group, n = first 50 patients enrolled) or AlloTC-MCP care (n = next 50 patients enrolled) over a 6-month VTE treatment follow-up period...

INTRODUCTION: The incidence of cardiovascular events among cancer patients with bone metastases is poorly understood. We examined rates of cardiovascular events among cancer patients with bone metastases and mortality following such events. METHODS: Using Danish health registries, we identified all Danish cancer patients diagnosed with bone metastases (1994-2013) and followed them from bone metastasis diagnosis. We computed incidence rates (IR) per 100 person-years and cumulative incidence for first-time inpatient hospitalization or outpatient clinic visit for cardiovascular events, defined as myocardial infarction, ischemic stroke, or venous thromboembolism (VTE)...

INTRODUCTION: Recurrent venous thromboembolism (VTE) despite curative anticoagulation is frequent in patients with cancer. Identifying patients with a high risk of recurrence could have therapeutic implications. A prospective study was designed to validate the Ottawa risk score of recurrent VTE in cancer patients. METHODS: In a prospective multicenter observational cohort, adult cancer patients with a recent diagnosis of symptomatic or incidental lower limb deep vein thrombosis or pulmonary embolism (PE) were treated with tinzaparin for 6 months...

The role and effect of radiotherapy in the development of VTE has not been extensively explored; Methods: This is a post-hoc analysis from the COMPASS-CAT trial. Patients with breast, lung, colon or ovarian cancer, with early, locally advanced or metastatic disease and receiving chemotherapy were included. Primary endpoint was documented symptomatic VTE; Results: A total of 1355 patients were enrolled between November 2013 and November 2015. Of those, 194 patients were excluded because of missing data or the use of anticoagulation...

BACKGROUND: The number of patients with atrial fibrillation (AF) and cancer is rapidly increasing in clinical practice. The impact of cancer on clinical outcomes in this patient population is unclear, as is the performance of the HAS-BLED (Hypertension, Abnormal Renal/Liver Function, Stroke, Bleeding History or Predisposition, Labile INR, Elderly, Drugs/Alcohol) and CHA2 DS2 -VASc (Congestive Heart Failure, Hypertension, Age ≥ 75 years, Diabetes Mellitus, Stroke or Transient Ischemic Attack, Vascular Disease, Age 65 to 74 Years, Sex Category) scores...

OBJECTIVE: The presence of cancer increases arterial thromboembolic events, specifically myocardial infarction and stroke, before a formal diagnosis of cancer. To the best of our knowledge, this increase in thrombotic risk has not been studied in patients with lower extremity bypass grafts. In the present study, we aimed to determine the effect of occult cancer on femoropopliteal bypass patency. METHODS: A retrospective review of femoropopliteal bypass procedures completed from 2001 to 2018 was performed...

BACKGROUND: - The management of venous thromboembolism (VTE) is particularly challenging in patients with cancer who undergo complex treatment protocols. Cancer patients often have comorbidities which may affect the efficacy and safety of anticoagulant treatments. Coordinated multidisciplinary management of these complex cases can help optimize delivery of individualized anticoagulant treatment. AIMS: - To describe the multidisciplinary team meeting (MDTM) for the management of VTE in cancer patients at our institution and to document outcomes in these patients...

BACKGROUND: Abemaciclib demonstrated efficacy in hormone receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer. Here we provide a comprehensive summary of the most common adverse events (AEs), their management, and whether AEs or dose reductions influenced progression-free survival (PFS), in the MONARCH 2 and 3 trials. MATERIALS AND METHODS: Incidence of the most clinically relevant AEs, management, and outcomes were summarized...

BACKGROUND: Breast cancer patients are at a four-fold increased risk of developing a venous thromboembolism (VTE), a major cause of death in this group. Conversely, coagulation factors promote tumour growth and metastasis. This has been evidenced in preclinical models, with an inhibitory effect of anticoagulants on cancer growth through proliferative, angiogenic, apoptotic, cancer stem cell and metastatic processes. The extrinsic clotting pathway is also more upregulated in patients in the relatively poorer prognosis oestrogen receptor (ER)-negative breast cancer subgroup, with increased tumour stromal expression of the coagulation factors Tissue Factor and thrombin...

Guidelines provide differing recommendations regarding direct-acting oral anticoagulants vs low-molecular-weight heparin (LMWH) for treatment of cancer-associated thrombosis (CAT). This study was undertaken to evaluate the effectiveness and safety of rivaroxaban vs LMWH for treatment of CAT. Using US Surveillance, Epidemiology and End Results-Medicare-linked data from 2013 through 2016, we evaluated adults with active breast, lung, ovarian, or pancreatic cancer, who were admitted to the hospital or treated in the emergency department for CAT and were prescribed rivaroxaban or LMWH for outpatient anticoagulation...
