Predictors of interstitial brachytherapy utilization in locally advanced cervical cancer and impact on overall survival

Abstract

Our work supports the growing body of literature on BT utilization impacted by patient race and treatment facility. Patients with a higher stage of cervical cancer and those treated at a high volume or academic center were more likely to receive interstitial BT, reflecting appropriate intensification of therapy for larger tumors. Interstitial BT did not indicate an OS benefit. Further study could lead to improved understanding of barriers to accessing interstitial brachytherapy.
