Racial disparities in histological subtype, stage, tumor grade and cancer-specific survival in lung cancer.

ABSTRACT:

Background

Racial differences in lung cancer survival are well documented in the United States, but the fundamental causes are less clear. In this study we aimed to examine racial differences in lung cancer-specific survival (LCSS) and explore mediating factors.

Methods

We used the Surveillance, Epidemiology and End Results database to obtain data pertaining to lung cancer patients from 2004 to 2017. Outcome was LCSS and covariates included nonclinical (age at diagnosis, gender, marital status, race) and clinical factors (tumor site, year of diagnosis, tumor grading, histological subtype, tumor-node-metastasis (TNM) stage, surgery status, chemotherapy status and radiation status). Kaplan-Meier methods served for comparative LCSS disparities among patients of different racial
