e23318 Background: There is a shared hypercoagulable association of COVID-19 and cancer, noting an increased risk of thromboembolic events (TEE)in both conditions. The current study focuses on patients with concurrent COVID-19 and underlying cancer and compares incidence of TEE and related outcomes in this complex intersection of acute viral infection and oncological challenges. Methods: In this retrospective cohort study, we examined data from the Charleston Area Medical Center’s (CAMC) COVID-19 Registry, involving 5,479 adult, symptomatic, PCR-positive COVID-19 hospitalized patients (3/1/2020 to 1/20/2024). Demographics, co-morbidities, lab values, treatments, and outcomes were assessed. Propensity score matching (3:1) non-cancer patients vs those with an active cancer diagnosis was undertaken using sex and age. SAS 9.4 was utilized for the analysis. The groups were compared using Chi-square/Fisher’s Exact tests for categorical variables and t-tests for continuous variables and a logistic regression modelling to determine differences in key variables, the incidence of thromboembolic events and other outcomes. Results: After propensity matching, 1,623 non-cancer and 427 active cancer patients were included. The incidence of venous thromboembolism (VTE) was higher in the active cancer group (9.42% vs 4.2%, P 2.5 mg/L, it was not performed consistently. The active cancer group had greater frequencies of abnormal ferritin levels (59.1% vs 49.1%, P=0.01), and elevated procalcitonin levels > 0.05 ng/mL (72.9% vs 60.6%, p / = 7days was also a predictor of TEE (OR= 1.825 95% CI 1.1-2.9 P < 0.01). Conclusions: Symptomatic VTE rates in our COVID-19 and active cancer cohort align with published studies. Diligence in evaluation of D-dimer, early detection of TEE and adherence to published guidelines in prophylaxis and treatment is recommended.
