Evaluation of outcome by race in early-stage non-small cell lung cancer

Most studies of outcome by race in cancer have shown that blacks have a shorter survival compared to whites, both overall and within each TNM stage. We endeavored to evaluate the difference in survival by race in US military veterans treated for early stage non-small cell lung cancer (NSCLC). This retrospective analysis of overall survival by race, looking at all-cause mortality in a group of consecutively treated veterans with stage I-II NSCLC, was carried out at a 1,000-bed tertiary care Department of Veterans Affairs Medical Center. The study included 143 white and 45 black patients treated with curative intent for stage I-II NSCLC between January 1982 through August 1994. Nineteen patients received radiotherapy alone for their treatment while the remaining 169 underwent a complete surgical resection. There were no significant differences in patient characteristics for important prognostic variables. An overall survival analysis of all-cause mortality found no significant difference between the two groups. With equal access to health care, as is available for eligible patients in Department of Veterans Affairs Medical Centers, racial differences in lung cancer treatment outcome may be diminished or eliminated.
