Abstract


Background: The aim of the study was to evaluate and compare the efficacy, tolerability and toxicity of three palliative radiotherapy (RT) schedules in locally advanced head and neck carcinoma (LAHNC), i.e. Quad Shot schedule, Christie schedule and conventional palliative schedule.

Methods: The patients were randomly divided into three groups of 30 each. Group I patients were planned for 14.8 Gy in 4 fractions over 2 days, repeated three weekly for two more cycles. Group II patients were planned for 50 Gy in 16 fractions over 3.1 weeks. Group III patients were planned for 20 Gy in 5 fractions over 5 days, repeated after an interval of 3 weeks. The quality of life was assessed before and after RT using University of Washington Quality of Life questionnaire version 4.

Results: Local control rates were 84%, 76%, and 76% for groups I, II and III, respectively. Disease status at 6-month follow-up was no evidence of disease (20%, 28%, and 16%), residual disease (72%, 48%, and 76%), and recurrent disease (8%, 24%, and 8%) in groups I, II and III, respectively. Grade III acute skin reactions were 28%, 44%, and 16% in groups I, II and III, respectively. Grade III acute mucosal reactions were 36%, 56%, and 24% in group I, II and III, respectively. Quality of life improved in all groups after RT.

Conclusion: Quad Shot schedule may be used in LAHNC with better local control and acceptable toxicity as compared to conventional palliative RT schedule in Indian setting.
