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
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). Individuals with kidney or bladder cancer who initiated ICI between 01/01/2015 and 12/31/2020 were recruited. Minimum follow-up was 6 months (except in cases of demise). The primary objective was to calculate the incidence of ICI-associated VTE/AT and secondary objectives included to analyze their impact on survival and identify variables predictive of VTE/AT. RESULTS: 210 patients with kidney cancer were enrolled. The incidence of VTE/AT during follow-up (median 13 months) was 5.7%. Median overall survival (OS) was relatively lower among subjects with VTE/AT (16 months, 95% CI 0.01-34.2 vs. 27 months, 95% CI 22.6-31.4; p = 0.43). Multivariate analysis failed to reveal predictive variables for developing VTE/ AT. 197 patients with bladder were enrolled. There was a 9.1% incidence rate of VTE/AT during follow-up (median 8 months). Median OS was somewhat higher in patients with VTE/AT (28 months, 95% CI 18.4-37.6 vs 25 months, 95% CI 20.7-29.3; p = 0.821). Serum albumin levels < 3.5 g/dl were predictive of VTE/ AT (p < 0.05). CONCLUSIONS: There appears to be no association between developing VTE/AT and ICI use in patients with renal or bladder cancer. Serum albumin levels are a predictive factor in individuals with bladder 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. 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
There is no standard chemotherapy regimen in advanced gastric cancer with poor performance status and hepatic dysfunction. New chemotherapeutical agents and targeted therapy have demonstrated promising results in terms of efficacy and safety in phase II clinical trials. We report the case of a 68-year-old man with stage IV gastric cancer and severe hepatic dysfunction due to liver metastases treated with a combination of oxaliplatin, 5-fluorouracil and cetuximab.
