Early VTE is a strong prognostic factor in advanced PDAC, occurring in about one in 10 patients.
Background There are still controversial data regarding the prognostic value of Venous ThromboEmbolism (VTE) in advanced Pancreatic Ductal AdenoCarcinoma (PDAC) and thromboprophylaxis is poorly prescribed despite international recommendations. Methods Medical charts of patients consecutively treated for advanced PDAC from 2010 to 2019 were retrospectively reviewed. Progression-free survival (PFS) and overall survival (OS) were estimated using Kaplan-Meier method. Prognostic Factors were identified using a multivariate Cox's proportional hazard model. Early VTE was defined as VTE occurring within the three months following the PDAC diagnosis. Results A total of 174 patients were included (median age: 67 years; males: 55.2%; performance status (PS) 0-1: 88.5%) with metastatic disease in 74.7%. At baseline, Khorana score was high (>= 3) in the vast majority of cases (93.7%). The cumulative incidences of VTE were 12.4% (95% CI 7.3-17.2) at 3 months, 20.4% (95% CI 13.9-26.4) at 6 months and 28.1% (95% CI 20.0-35.3) at 12 months. Patients who experienced early VTE had shorter PFS (3.8 months vs. 7.1 months; HR = 2.02; 95% CI 1.21-3.37; p = 0.006) and shorter OS (8.0 months vs. 14.1 months; HR = 2.42; 95% CI 1.37-4.30; p = 0.002) compared to the others, independently of prognostic factors such as PS, liver metastases, carcinomatosis, and chemotherapy regimen. Conclusion early VTE is a strong prognostic factor in advanced PDAC and occurs in about one in 10 patients.
