Patients with gastric cancer (GC) are at higher risk of thromboembolism when compared to other solid tumors. We aim to determine the predictive performance of current venous thromboembolism (VTE) predictive tools and their variability and validity after first treatment. Single institution cohort of GC-treated patients (2010*15). We abstracted predictive tools, validated for VTE prediction in patient with cancer; including the Khorana Score (KRS), platelet to lymphocyte ratio (PLR), and neutrophil to lymphocyte ratio (NLR). The primary outcome was CAT prediction. We included 112 patients who were predominantly men (66%), 58 (51-64)-year-olds, with adenocarcinoma (84%) and advanced disease (59%). The median follow-up was 21.3 months (9.5-42.6). The VTE occurrence was 12%. The median time from diagnosis to VTE occurrence was 59 days (36-258). In our cohort, performance status (PS; hazard ratio [HR], 8.02; 95% confidence interval [CI], 2.37-27.14; P < .01) was an independent predictor of VTE whereas KRS (univariate HR, 2.3; 95% CI, 0.7-7.4; P = .17), PLR (univariate HR, 0.8; 95% CI, 0.2-3.1; P = .8), and NLR (univariate HR, 0.8; 95% CI, 0.3-2.5; P = .8) at baseline were not associated with VTE risk. The posttreatment KRS was an independent predictor of VTE (HR, 3.69; 95% CI, 1.17-11.65; P = .25) along with PS (HR, 7.58; 95% CI, 2.27-25.33; P = .01). Posttreatment KRS appears as a valid tool to identify patients with GC at high risk of VTE after first cancer treatment.
