High-dose-rate interstitial brachytherapy in oral cancer-Its impact on quality of life.
2016
Abstract Purpose The aim of the study was to assess the impact of high-dose-rate (HDR) interstitial brachytherapy on quality of life (QOL) in oral cancer. Methods and Materials Thirty-two patients of oral cancer treated at our institute from January 2010 to December 2014 with radical radiotherapy (external beam radiotherapy + brachytherapy) were included for analysis; 30 patients received external beam radiotherapy (50–54 Gy) and HDR brachytherapy boost (18–24.5 Gy); 2 patients received radical HDR brachytherapy (31.5 Gy). Quality of life (QOL) was assessed by Telugu, Hindi, and English versions of EORTC Quality of Life Core-30 and EORTC Quality of Life Head and Neck Module (QLQ HN 2 patients were re-irradiation cases. On excluding these cases, 27 patients were available for analysis. The followup duration was 6–55 months. At the time of analysis, 91% (29) patients were disease free, 3% (1) progressed, and 6% (2) died. At the end of 2 years, none of the QLQ-C30 functional scores fell below the baseline. Pain, swallowing, sensory, speech, social contact, and social eating worsened at 3 months but improved over 2 years ( p p p Conclusions Almost all patients regained normal function after treatment and reported an excellent QOL at 2 years. However, tumor stage significantly affected the QOL.
