INTRODUCTION: Food desert (FD) residence has emerged as a risk factor for poor outcomes in breast, colon and esophageal cancers. The purpose of this retrospective study was to examine FD residence as an associated risk factor in nonsmall cell lung cancer (NSCLC) patients treated with anatomic lung resection (ALR).
METHODS: All consecutive ALRs for stage I-III NSCLC from January 2015 to December 2017 at a single institution were reviewed. The primary exposure of interest was FD residence as defined by the United States Department of Agriculture. The primary outcome was 5-y overall mortality. Secondary outcomes were 30-d complications and 1- and 3-y mortality. Cox proportional hazard analysis was used to model factors associated with each outcome, adjusted for covariates.
RESULTS: A total of 348 ALRs were included, with 101 (29%) patients residing in an FD. In the unadjusted Cox model, those residing in FD had an associated lower 5-year mortality risk compared to those not residing in an FD (hazard ratio = 0.56, 95% confidence interval (0.33-0.97); P = 0.04). That association was not statistically significant once adjusted for covariates (hazard ratio = 0.59, 95% confidence interval (0.34-1.04); P = 0.07).
CONCLUSIONS: In this study, FD residence was not associated with an increase in the risk of 5-y mortality. Selection bias of patients deemed healthy enough to undergo surgery may have mitigated the negative association of FD residence demonstrated in other cancers. Future work will evaluate all NSCLC patients undergoing treatments at our institution to further evaluate FDs as a risk factor for worse outcomes.
