Cui YQ, Tan XM, Liu B, et al. - Via a retrospective cohort study of 40 lung cancer patients with pulmonary embolism (PE) and 60 lung cancer patients without PE (non‐PE group), researchers sought to determine the risk factors of lung cancer complicated with PE. Observations suggest PE predicts a poor prognosis in lung cancer patients. In multivariate analysis, they identified PE to be independently associated with high D‐dimer, chemotherapy, DVT, stages III to IV, and adenocarcinoma. Patients in the case group had significantly shorter overall survival than the control group with a median survival duration of 10.5 months vs 16.8 months.
