Abstract

Objective: The aim of the studywas to determinewhether patient characteristics are associated with radiation treatment noncompliance. Methods/Materials: We retrospectively studied 244 patients with cervical cancer treated with chemoradiation between May 2006 and August 2015 at a safety net health center. Compliance with treatment was defined as missing less than 2 days of scheduled radiation. Results: Treatment records revealed a compliance rate of 50.8% in this population. Factors associated with noncompliance were younger age (hazard ratio [HR], 1.037; P = 0.004), presence of psychiatric diagnosis (HR, 0.581; P = 0.044), and having insurance (HR, 0.484; P = 0.022). Noncompliance was associated with a decrease in disease-free survival (HR, 0.555; P = 0.042) but was not associated with overall survival. International Federation of Gynecology and Obstetrics stage was associated with detriment in overall survival on multivariate analysis (HR, 2.034; P = 0.001). Conclusions: Younger patients, those with psychiatric illness, and those with insurance define a group that is more likely to be noncompliant with treatment and hence may require up-front intervention to improve outcomes.
