“…In the Surveillance, Epidemiology, and End Results (SEER) Survey from 2010 to 2015, among the age, race, sex, stage, primary site, histologic type, chemotherapy and radiation parameters, only age, stage, and chemotherapy have been reported to be associated with survival in patients with resected SCLC [5]. Sex [55], visceral pleural invasion [56], lymphocyte-tomonocyte ratio [57], adjuvant chemotherapy after surgical resection [58], TNM stage and tumor location [59], and negative lymph node (NLN) [60] are among other factors reported to be associated with OS in patients who underwent surgical resection. In this study, sex and UICC stage were found to be associated with overall survival in the EGAD00001001244 and GSE60052 cohorts, respectively.…”
