ABSTRACT

BACKGROUND: Venous thromboembolism (VTE) is a potentially preventable serious complication in lung cancer patients undergoing thoracic surgery. We examined the risk and timing of VTE following surgery for primary non-small cell lung cancer (NSCLC).

METHODS: in the Danish Lung Cancer Registry. VTE events in the year after surgery were assessed by stage, patient characteristics, and surgical procedure.

RESULTS: We identified 13,197 patients who underwent surgery for NSCLC in 2003-2021 (mean age 67.6 years, 50% female); 10,524 (79.7%) had stage I-II NSCLS and 2673 (20.3%) had stage III-IV. During one-year follow-up, there were 335 VTE events, yielding a rate of 2.87 events/100 person-years and an absolute risk of 3.3% (95% CI 2.3-4.0). VTE risk increased with advancing cancer stage (1.8% for stage I versus 4.1% for stage IV), but varied little by pathological type, sex, and comorbidity level. Bilobectomy was associated with highest VTE risk (4.8%, 95% CI 3.2-6.9), followed by pneumonectomy (3.6%, 95% CI 2.5-5.1). The hazard of VTE was highest during the first three months after surgery, whereafter it declined. For stage IV cancer hazards increased again after six months. At one-year, all-cause death was 12.6% (95% CI: 12.0-13.1 %).

CONCLUSIONS: Among patients undergoing surgery for NSCLC, 3.3% developed VTE, most commonly within 3 months postoperatively. Prolonged thromboprophylaxis could be considered, particularly in those with advanced cancer stage and undergoing extended resections.
