ABSTRACT
BACKGROUND: Venous thromboembolism (VTE) is a major cause of morbidity and mortality in patients undergoing oncologic operations. We sought to identify risk factors for postoperative VTE to define high-risk groups that may benefit from enhanced prophylactic measures. METHODS: A retrospective cohort analysis using The Society of Thoracic Surgeons General Thoracic Surgery Database was conducted on patients who underwent lung cancer resection between 2009 and 2021. Baseline characteristics and postoperative outcomes were compared between patients who did and did not develop a postoperative pulmonary embolism (PE) or deep venous thrombosis. Multivariable regression models identified risk factors associated with VTE. RESULTS: Of 57,531 patients who underwent lung cancer resection, a postoperative PE developed in 758 (1.3%). Patients with PE were more likely to be Black (12% vs 7%, P < .001), have interstitial fibrosis (3% vs 2%, P = .016), and prior VTE (12% vs 6%, P < .001). Postoperative PE was most likely to develop in patients with locally advanced disease who underwent bilobectomy (6% vs 4%, P < .001) or pneumonectomy (8% vs 5%, P < .001). Patients with postoperative PE had increased 30-day mortality (14% vs 3%, P < .001), reintubation (25% vs 8%, P < .001), and readmission (49% vs 15%, P < .001). On multivariable analysis, Black race (odds ratio, 1.74; 95% CI, 1.39-2.16; P < .001), interstitial fibrosis (odds ratio, 1.77; 95% CI, 1.15-2.72; P = .009), extent of resection, and increased operative duration were independently predictive of postoperative PE. A minimally invasive approach compared with thoracotomy was protective. CONCLUSIONS: Because nonmodifiable risk factors (Black race, interstitial fibrosis, and advanced-stage disease) predominate in postoperative PE and VTE-associated mortality is increased, enhanced perioperative prophylactic measures should be considered in high-risk cohorts.

The clinical and radiographic aspects of sarcoidosis and malignancy might mimic one another, making the distinction between the two difficult in some cases. Although there have been many theories on the link between sarcoidosis and malignancy, the association remains unproven. An unfortunate consequence of the presence of both entities in the same patient is the risk of misdiagnosis and incorrect treatment. We describe 3 patients who presented with locally advanced breast cancer and who were found to have pulmonary findings for metastatic disease that were proven upon biopsy to be consistent with sarcoidosis.
