RESUMO
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. Continuous variables were compared using Wilcoxon or Student's T test, and categorical variables were compared using the Chi-Square or Fisher's exact text among patients with and without VTE. A Log-Rank test was performed to detect mortality differences between the groups. RESULTS: A total of 118 patients were included. VTE global incidence was 4.2% (n = 5), and mortality 25.4% (n = 30). Obesity (p = 0.05), recent chemotherapy (p = 0.049) and use of steroids (p = 0.006) were related to higher risk of VTE in the univariate analysis, although they were not confirmed in the multivariate analysis as independent risk factors. Statistically significant differences in all-cause, COVID-19-related and cancer-related mortality according to the Khorana risk score (KRS) were observed. CATS-MICA score (CMS) also showed statistically significant differences in mortality between low- and high-risk patients. Prediction of risk of VTE development with these scores showed a tendency towards significance. CONCLUSIONS: In this cohort, VTE incidence was similar to previously reported in the general population with SARS-CoV-2 infection. KRS was associated with overall and specific-cause mortality, and might be a useful prognostic tool in this setting.
RESUMO
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. RESULTS: 197 patients were included, 54 (27.4%) developed a VTE. Early appearance of VTE was associated with worse prognosis: median overall survival (mOS) VTE < 3 months 8.5 months (HR 1.65, 95% CI 1.11-2.46; p = 0.014), mOS VTE > 3 months 12.8 months (HR 0.78, 95% CI 0.39-1.54; p = 0.5) and mOS patients without VTE 11.4 months (95% CI 10.1-15.4). There was no significant association between the patient's VTE risk according to the Khorana risk score (KRS) (chi2 test p-value = 0.9). CONCLUSION: Early VTE is a prognostic factor in PDAC, which may identify a more aggressive subtype.

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. The estimation of the relative frequency θ of complications based on the EPIPHANY Index categories was made using the Bayesian alternative for the binomial test. RESULTS: A total of 900 patients, who were diagnosed with PE between October 2017 and January 2020, were enrolled. The rate of serious complications at 15 days was 11.8%, 95% highest density interval [HDI], 9.8-14.1%. Of the EPIPHANY low-risk patients, 2.4% (95% HDI, 0.8-4.6%) had serious complications, as did 5.5% (95% HDI, 2.9-8.7%) of the moderate-risk participants and 21.0% (95% HDI, 17.0-24.0%) of those with high-risk episodes. The EPIPHANY Index was associated with overall survival (OS) in patients with different risk levels: median OS was 16.5, 14.4, and 4.4 months for those at low, intermediate, and high risk, respectively. Both the EPIPHANY Index and the Hestia criteria exhibited greater negative predictive value and a lower negative likelihood ratio than the remaining models. The incidence of bleeding at 6 months was 6.2% (95% HDI, 2.9-9.5%) in low/moderate-risk vs 12.7% (95% HDI, 10.1-15.4%) in high-risk (p-value = 0.037) episodes. Of the outpatients, serious complications at 15 days were recorded in 2.1% (95% HDI, 0.7-4.0%) of the cases with EPIPHANY low/intermediate-risk vs 5.3% (95% HDI, 1.7-11.8%) in high-risk cases. CONCLUSION: We have validated the EPIPHANY Index in patients with incidental or symptomatic cancer-related PE. This model can contribute to standardize decision-making in a scenario lacking quality evidence.

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.

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. The objective of this article is to review the literature on the efficacy and safety of oral drugs available for the treatment of metastatic colorectal cancer (mCRC). Several such drugs have been developed, and fluoropyrimidines are the backbone of chemotherapy in this indication. They exert their antitumour activity by disrupting the synthesis and function of DNA and RNA. Oral fluoropyrimidines include prodrugs capecitabine, tegafur, eniluracil/5-fluorouracil, tegafur/uracil, tegafur/gimeracil/oteracil and trifluridine/tipiracil (FTD/TPI). Oral drugs offer several advantages over injectable formulations, including convenience, flexibility, avoidance of injection-related adverse events (AEs) and, in some circumstances, lower costs. However, oral drugs may not be suitable for patients with gastrointestinal obstruction or malabsorption, they may result in reduced treatment adherence and should not be co-administered with drugs that interfere with absorption or hepatic metabolism. Oral fluoropyrimidines such as capecitabine, as monotherapy or in combination with oxaliplatin, irinotecan or bevacizumab, are as effective as intravenous 5-fluorouracil (5-FU) in first-line treatment of mCRC. Other oral fluoropyrimidines, such as FTD/TPI, are effective in patients with mCRC who are refractory, intolerant or ineligible for 5-FU. In addition, oral fluoropyrimidines are used in adjuvant treatment of mCRC. Regorafenib is an oral multikinase inhibitor used in patients in whom several previous lines of therapy have failed. Frequent AEs associated with oral drugs used in the treatment of CRC include hand-foot syndrome and gastrointestinal and haematological toxicities.
RESUMO
INTRODUCTION: Based on the high incidence of thromboembolic events (TEs) observed in lung adenocarcinomas with ALK translocations and taking into account the biological proximity of ROS1 and ALK, we conducted a retrospective analysis of patients with advanced lung carcinoma carrying rearrangements in ROS1 from 23 centres in Spain and one centre in Portugal. METHODS: The main objective of the study was to analyse the incidence of TE in this population, looking for predictive risk factors, and its impact on overall survival. RESULTS: A total of 58 patients were included. The incidence of TEs throughout the disease was 46.6% (n = 27) with a median follow-up of 19 months (range: 1-78 months) and a median overall survival of 52 months in the total population and 50 months for the patients presenting TEs, with a hazards ratio of 1.12 (95% confidence interval: 0.47-2.65) p = 0.78. The majority of the events were venous (n = 24; 89%) and occurred in the ambulatory setting (n = 18; 67%). Almost half of the patients (n = 13; 48%) presented the TE in the peri-diagnostic period. CONCLUSIONS: The high incidence of thrombosis, especially during the cancer diagnosis process, requires special attention from a clinician. Despite the limitations of such a small descriptive study, its results are in accordance with previously reported data. It would be important to design prospective studies of antithrombotic prophylaxis in this population because of their possible impact in reducing the risk of TEs.

BACKGROUND: The ever-growing complexity of cancer-associated thrombosis (CAT), with new antineoplastic drugs and anticoagulants, distinctive characteristics, and decisions with low levels of evidence, justifies this registry. METHOD: TESEO is a prospective registry promoted by the Spanish Society of Medical Oncology to which 34 centers contribute cases. It seeks to provide an epidemiological description of CAT in Spain. RESULTS: Participants (N=939) with CAT diagnosed between July 2018 and December 2019 were recruited. Most subjects had advanced colon (21.4%), non-small cell lung (19.2%), and breast (11.1%) cancers, treated with dual-agent chemotherapy (28.4%), monochemotherapy (14.4%), or immune checkpoint inhibitors (3.6%). Half (51%) were unsuspected events, albeit only 57.1% were truly asymptomatic. Pulmonary embolism (PE) was recorded in 571 (58.3%); in 120/571 (21.0%), there was a concurrent deep venous thromboembolism (VTE). Most initially received low molecular weight heparin (89.7%). Suspected and unsuspected VTE had an OS rate of 9.9 (95% CI, 7.3-non-computable) and 14.4 months (95% CI, 12.6-non-computable) (p=0.00038). Six-month survival was 80.9%, 55.9%, and 55.5% for unsuspected PE, unsuspected PE admitted for another reason, and suspected PE, respectively (p<0.0001). The 12-month cumulative incidence of venous rethrombosis was 7.1% (95% CI, 4.7-10.2) in stage IV vs 3.0% (95% CI, 0.9-7.1) in stages I-III. The 12-month cumulative incidence of major/clinically relevant bleeding was 9.6% (95% CI, 6.1-14.0) in the presence of risk factors. CONCLUSION: CAT continues to be a relevant problem in the era of immunotherapy and targeted therapies. The initial TESEO data highlight the evolution of CAT, with new agents and thrombotic risk factors.

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. Patients diagnosed with iPE and active cancer were enrolled. Between May 2016 and May 2017, 25 consecutive patients were included in the study. RESULTS: All patients were assessed in the emergency room (ER) and started treatment with low-molecular weight heparins (LMWH) being discharged in the following 24 h. Congestive heart failure and right ventricular dysfunction were ruled out, and none of them presented massive PE, active bleeding or any disease-related reason that required hospitalization. The 90-day follow-up visit showed no venous thromboembolism (VTE) recurrence and the major bleeding rate was 4%. Mortality rate at 30 and 90 days was 0%. CONCLUSIONS: Outpatient management for iPE in cancer patients appears to be feasible and safe in selected cancer patients.
