{Abstract}: UNASSIGNED: The incidence of venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), after lung cancer resections varies in the literature, and there is limited evidence regarding the optimal duration of thromboprophylaxis. This study aimed at determining the early and long-term occurrence of thromboembolic complications in patients who received in-hospital thromboprophylaxis and underwent resective surgery for lung cancer.
UNASSIGNED: The study included all patients who underwent lung cancer surgery at Tampere University Hospital between 2004 and 2016. Postoperative thromboprophylaxis was administered for the duration of the hospitalization. Data on subsequent episodes of VTE and survival were obtained from national registries. The results were compared to a demographically matched reference population.
UNASSIGNED: The study comprised 435 patients and 4,338 individuals in the reference population. The overall occurrence of VTE in patients and the reference group was 0.3% vs. 0.2% at 90 days (P=0.56), 3.5% vs. 0.7% at 1 year (P<0.001), 9.2% vs. 2.2% at 3 years (P<0.001), and 18.7% and 3.9% at 5 years (P<0.001), respectively. The majority of cases represented PE. The overall mortality at 5 years was 44.4% vs. 11.6% (P<0.001). No associations between patient characteristics and the occurrence of VTE during follow-up were detected.
UNASSIGNED: Patients undergoing lung cancer surgery and who receive in-hospital medical thromboprophylaxis do not seem to be in high risk for symptomatic VTE during the early postoperative period. However, during long-term follow-up the occurrence of symptomatic VTE was significant.
