Prognostic factors of survival in patients with non-small cell lung cancer: a competing risk model using the SEER database

Abstract: Background: To explore the prognostic factors of survival in non-small-cell lung cancer (NSCLC) patients using the competing risk analysis.Methods: This was a retrospective cohort study. NSCLC patients with complete data were selected from the Surveillance, Epidemiology, and End Results (SEER) database between 2010 and 2015. Outcomes were censored, cancer-specific mortality in NSCLC, and other-cause mortality. Gray's test was used in univariable analysis, and a multivariable Fine-Gray competing risk model with… Show more

“…One strategy is to stratify patients according to KRAS mutational status together with other key prognostic factors, such as tumor size. Primary tumor size is an established prognostic factor in NSCLC, with larger tumors being associated with poorer survival (24,(31)(32)(33)(34). The reason for this association is not yet fully understood but larger tumors may be more resistant to therapy due to having poorer blood supply, differential metabolism, and potentially a higher likelihood of micrometastatic disease compared to smaller tumors (35).…”

“…Primary tumor size is an established factor in prognosis, with larger tumors associated with poorer survival [6][7][8][9][10]. The reason for this association is not yet fully understood but it is believed that larger tumors are more resistant to therapy due to having poorer blood supply, a different metabolism and potentially a higher likelihood of micrometastatic disease compared to smaller tumors.…”
