Disparities in lung cancer survival and receipt of surgical treatment
Abstract
Lung cancer accounts for the greatest proportion of cancer deaths in the United States. This study aims to characterize lung cancer survival by racial/ethnic group and ascertain any modifiable determinants of identified disparities in the newly diverse Mountain West by using the state of Nevada. 12,964 first primary lung cancer cases diagnosed between 2003 and 2010 were identified for analysis from the Nevada Central Cancer Registry and followed for vital status until December 31, 2011. Standardized age-adjusted five-year survival stratified by race/ethnicity was computed using life table methods. Hazard ratios adjusted for covariates were estimated using Cox proportional hazards regression modeling. Adjusted odds of receiving surgical treatment for localized non-small cell lung cancer by region of Nevada were compared using logistic regression. By the end of the follow-up period, 86% of lung cancer cases in Nevada were deceased. Five-year overall survival was 12.3% (95%CI: 11.5-13.1) for males and 18.9% (95%CI: 17.9-19.9) for females. Compared to cases in Northwestern Nevada, patients in Southern and Rural Nevada had 9% (HR:1.09; 95% CI:1.04-1.14) and 10% (HR:1.10; 95% CI:1.02-1.19) higher risk of dying from lung cancer, respe...Continue Reading

Cancer Disparities
Cancer disparities refers to differences in cancer outcomes (e.g., number of cancer cases, related health complications) across population groups.
