Abstract/OtherAbstract:
BACKGROUND AND OBJECTIVES: The objective of this study is to explore clinical risk factors for venous thromboembolism (VTE) in postoperative lung cancer patients in order to provide a basis for the prevention and treatment of postoperative VTE. METHODS: A total of 1,001 lung cancer patients were retrospectively analyzed. Each patient was confirmed with surgical pathology diagnosis and had a complete clinical and follow-up record. VTE was identified in a combination of spiral computed tomography (CT), pulmonary angiography, and color Doppler ultrasound. We used life table method to create an occurrence frequency curve of thrombosis. We also searched for high risk factors for postoperative VTE with Cox multivariate regression model and created frequency curves of thrombosis against different risk factors using Kaplan-Meier method. RESULTS: As of July 31, 2011, the median follow-up time is 25.73 ± 0.11 months (19.23-31.37). The cumulative frequency of VTE among 1,001 lung cancer patients is 2%, 3%, 4%, 5%, and 5.3% over 1, 3, 6, 12, and 30 months after the surgery. COX regression analysis showed that the hazard ratio of VTE occurrence in patients with incomplete resection relative to ones with complete resection is 9.867 (95% CI: 5.275-18.459, P = 0.000). And the hazard ratio of VTE occurrence is 3.472 (95% CI: 1.761-6.845, P = 0.000) in patients with anti-angiogenesis treatment compared to patients without such treatment. The hazard ratio of VTE occurrence is 2.808 (95% CI: 1.439-5.479, P = 0.002) in patients with EGFR-TKI treatment relative to patients without the treatment, and 7.520 (95% CI: 3.968-14.250, P = 0.000) in patients with an increase in D-dimer level relative to normal ones CONCLUSIONS: The highest incidence of VTE is within 1 month after lung cancer surgery. High risk factors for VTE include incomplete surgical resection, postoperative use of anti-angiogenesis drugs, EGFR-TKI application and an increase in preoperative D-dimer level. J. Surg.
