Prognostic factors for survival in patients with metastatic lung adenocarcinoma: An analysis of the SEER database

Abstract

SIGNIFICANT FINDINGS OF THE STUDY: Regression analysis identified poor prognostic factors for overall survival. Factors were male sex, age ≥ 65 years, lack of family support and presence of liver, bone and brain metastases. Patients with liver metastasis showed the highest HR (HR = 1.45 95% CI: 1.40-1.50). This study included the highest number of adenocarcinoma patients analyzed so far (N = 46 030). What this study adds The presence of liver metastases should be considered as a stratification factor for future studies evaluating new cancer treatments including immunotherapy.
