Effect of Prior Cancer on Outcomes in Advanced Lung Cancer: Implications for Clinical Trial Eligibility and Accrual [1]
Usually patients with prior cancer are excluded in lung cancer trials, but the impact on survival in lung cancer is not known. In a cohort of 102929 patients older than 65 with stage IV lung cancer, a propensity score analysis were performed and found that patients with prior cancer had better survival (all-cause and lung cancer-specific). Therefore these patients with prior cancer should be considered candidates for clinical trials for advanced lung cancer.
