Prediction model for major bleeding in anticoagulated patients with cancer-associated venous thromboembolism using machine learning and natural language processing.

Purpose: We developed a predictive model to assess the risk of major bleeding (MB) within 6 months of primary venous thromboembolism (VTE) in cancer patients receiving anticoagulant treatment. We also sought to describe the prevalence and incidence of VTE in cancer patients, and to describe clinical characteristics at baseline and bleeding events during follow-up in patients receiving anticoagulants.

Methods: This observational, retrospective, and multicenter study used natural language processing and machine learning (ML), to analyze unstructured clinical data from electronic health records from nine Spanish hospitals between 2014 and 2018.

Thrombosis in breast cancer patients on cyclin-dependent kinase inhibitors: Survival impact and predictive factors - A study by the cancer and thrombosis group of the spanish society of medical oncology (SEOM).

Thrombosis may be included in the profile of side effects associated with CDK4/6 inhibitors. Its significance might be greater than reported in randomized clinical trials. To investigate this, a retrospective, multicenter study was conducted.

Impact of COVID-19 in the incidence of venous thromboembolism (VTE) and clinical outcomes in cancer patients: a cohort study.

Purpose: To determine the incidence of VTE and clinical outcomes in a cohort of cancer patients and COVID-19 infection, and to establish possible predictive factors of VTE.

Methods/patients: A single-center retrospective cohort study was performed to determine the incidence of VTE and mortality in 118 cancer patients with SARS-CoV-2 infection from March to August 2020. We calculated individual Khorana Risk and CATS-MICA scores in order to evaluate their utility to identify risk of VTE or death.

Immune checkpoint inhibitors-associated thrombosis in patients with head and neck cancer: a study of the Spanish society of medical oncology (SEOM) thrombosis and cancer group.

Purpose: Both venous and arterial thrombotic events (VTE/AT) can be associated with Immune Checkpoint Inhibitors (ICI). However, there is a paucity of information apropos patients in routine clinical practice.

Methods: /Patients.

Chronological pattern of venous thromboembolism (VTE) occurrence impacts in survival of pancreatic ductal adenocarcinoma (PDAC).

Background: Limited data exist on the prognostic significance of the chronology of VTE in patients with PDAC.

Methods: Medical data and survival characteristics of patients treated for PDAC from 2019 to 2021 were retrospectively reviewed. Early VTE was defined as occurring within the three months of PDAC diagnosis.

Validation of the CoVID-TE model as a tool to predict thrombosis, bleeding, and mortality in the oncology patient with Sars-Cov-2 infection: a study by the SEOM cancer and thrombosis group.

Purpose: The CoVID-TE model was developed with the aim of predicting venous thrombotic events (VTE) in cancer patients with Sars-Cov-2 infection. Moreover, it was capable of predicting hemorrhage and mortality 30 days following infection diagnosis. The model is pending validation.

Prediction of serious complications in patients with pulmonary thromboembolism and solid cancer: Validation of the EPIPHANY Index in a prospective cohort of patients from the PERSEO study.

Introduction: There is currently no validated score capable of classifying cancer-associated pulmonary embolism (PE) in its full spectrum of severity. This study has validated the EPIPHANY Index, a new tool to predict serious complications in cancer patients with suspected or unsuspected PE.

Method: The PERSEO Study prospectively recruited individuals with PE and active cancer or receiving antineoplastic therapy from 22 Spanish hospitals.

Immune checkpoint inhibitor-associated thrombosis in patients with bladder and kidney cancer: a study of the Spanish Society of Medical Oncology (SEOM) thrombosis and cancer group.

Purpose: Both venous and arterial thrombotic events (VTE/AT) can be associated with immune checkpoint inhibitors (ICI). However, there is a paucity of information apropos patients in routine clinical practice.

Methods/patients: Retrospective, multicenter study promoted by the Thrombosis and Cancer Section of the Spanish Society of Medical Oncology (SEOM).

Treatment modalities in cancer-associated venous thromboembolism (VTE).

Anticoagulation is the cornerstone of cancer-associated VTE treatment, including vitamin K antagonists (VKA), unfractionated heparin (UFH), fondaparinux, low-molecular-weight heparins (LMWH) and direct oral anticoagulants (DOACs). The goals of anticoagulant therapy in cancer patients with cancer-associated thrombosis (CAT) are to improve symptoms, reduce risk of recurrent VTE or fatal pulmonary embolism (PE), and decrease the risk of post-thrombotic syndrome (PTS) and chronic thromboembolic pulmonary hypertension. Although LMWH have been the standard of care for a long time for VTE treatment in cancer patients, showing superiority over the classic VKA, in the recent years the landscape of anticoagulant therapy has significantly changed with the inclusion of DOACs in this population.

Incidence, risk factors, and evolution of venous thromboembolic events in patients diagnosed with pancreatic carcinoma and treated with chemotherapy on an outpatient basis.

Background: Pancreatic carcinoma is one of the tumors associated with a higher risk for thromboembolic events, with incidence rates ranging from 5% to 41% in previous retrospective series.

Patients And Methods: We conducted a retrospective study in eleven Spanish hospitals that included 666 patients diagnosed with pancreatic carcinoma (any stage) between 2008 and 2011 and treated with chemotherapy. The main objective was to evaluate the incidence of venous thromboembolic events (VTE) in this population, as well as potential risk factors for thrombosis.

Management of Cancer-Associated Thrombosis: Unmet Needs and Future Perspectives.

Patients with cancer are at a high risk of symptomatic venous thromboembolism (VTE), which is a common cause of morbidity and mortality in this patient population. Increased risk of recurrent VTE and bleeding complications are two major challenges associated with therapeutic anticoagulation in these patients. Long-term therapy with low-molecular-weight heparins (LMWHs) has been the standard of care for the treatment of cancer-associated VTE given its favorable risk-benefit ratio in comparison with vitamin K antagonists.

Oral drugs in the treatment of metastatic colorectal cancer.

Colorectal cancer (CRC) is one of the most common forms of cancer, with an estimated 1.36 million new cases and almost 700,000 deaths annually. Approximately 21% of patients with CRC have metastatic disease at diagnosis.

Randomized Phase III Study of FOLFOX Alone or With Pegilodecakin as Second-Line Therapy in Patients With Metastatic Pancreatic Cancer That Progressed After Gemcitabine (SEQUOIA).

Purpose: SEQUOIA compared efficacy and safety of adding pegilodecakin (PEG), a pegylated recombinant human interleukin (IL)-10, with folinic acid, fluorouracil, and oxaliplatin (FOLFOX) in patients following progression on first-line gemcitabine-containing therapy with metastatic pancreatic ductal adenocarcinoma (PDAC).

Patients And Methods: SEQUOIA, a randomized, global phase III study, compared FOLFOX with PEG + FOLFOX as second line in gemcitabine-refractory PDAC. Patients were randomly assigned 1:1 (PEG + FOLFOX:FOLFOX) and stratified by prior gemcitabine and region.

Thrombosis and Coagulopathy in COVID-19.

Since December 2019, an outbreak of coronavirus disease 2019 (COVID-19) which initially occurred in the city of Wuhan, located in China's Hubei province, spread around the world and on March 11, 2020, the World Health Organization declared the new Coronavirus disease 2019 (COVID-19) as a pandemic. The presence of comorbidities (eg, cardiovascular disease, obesity), Sepsis Induced Coagulopathy score >4, elevation of D-dimer (>6 times the normal value), C-reactive protein, troponins and other disseminated intravascular coagulation markers; is associated to a worse prognosis in hospitalized patients with severe COVD-19, reaching a hospital mortality of 42%. Initial anticoagulant treatment with low molecular weight heparin has been shown to reduce mortality by 48% at 7 days and 37% at 28 days and achieve a significant improvement in the arterial oxygen pressure/inspired fraction of O2 (PaO2/FiO2) by mitigating the formation of microthrombi and associated pulmonary coagulopathy.

Pharmacological cancer treatment and venous thromboembolism risk.

Risk factors for cancer-associated thrombosis are commonly divided into three categories: patient-, cancer-, and treatment-related factors. Currently, different types of drugs are used in cancer treatment. Chemotherapy has been identified as an independent risk factor for venous thromboembolism (VTE).

A Case-Control Analysis of the Impact of Venous Thromboembolic Disease on Quality of Life of Patients with Cancer: Quality of Life in Cancer (Qca) Study.

Although there is published research on the impact of venous thromboembolism (VTE) on quality of life (QoL), this issue has not been thoroughly investigated in patients with cancer-particularly using specific questionnaires. We aimed to examine the impact of acute symptomatic VTE on QoL of patients with malignancies. This was a multicenter, prospective, case-control study conducted in patients with cancer either with (cases) or without (controls) acute symptomatic VTE.

Outpatient management of incidental pulmonary embolism in cancer patient.

Purpose: Incidentally discovered pulmonary embolism is a prevalent clinical problem for cancer patients and contributes significantly to the burden of cancer-associated thrombosis. The aim of this study was to explore if outpatient management of incidental pulmonary embolism (iPE) in cancer patients is effective and can be conducted safely.

Methods/patients: We performed a prospective observational cohort study in a single Spanish tertiary hospital.

Multivariable clinical-genetic risk model for predicting venous thromboembolic events in patients with cancer.

Background: Venous thromboembolism (VTE) is a leading cause of death among patients with cancer. Outpatients with cancer should be periodically assessed for VTE risk, for which the Khorana score is commonly recommended. However, it has been questioned whether this tool is sufficiently accurate at identifying patients who should receive thromboprophylaxis.
