Palliative split-course hypofractionated radiotherapy for incurable mucosal squamous cell head and neck cancer: a 10 year experience
Published online by Cambridge University Press: 21 September 2015
Abstract
Locally advanced head and neck cancer can be a distressing disease due to a variety of reasons. This retrospective study looks at the tolerability and outcomes for palliative split-course hypofractionated radiotherapy for this group of patients treated in our centre.
A total of 59 patients were treated with hypofractionated split-course radiotherapy for incurable mucosal squamous cell carcinoma of the head and neck region in our centre over a 10-year period. In all, 71% had stage IV disease. Radiotherapy consisted of three phases of 14·4 Gy/phase, in four to eight fractions over 4 days giving one·8–3·6 Gy/fraction. The phases were separated by 2 weeks. A total of 40 patients (63%) completed all three phases. A total of 72% patients had no acute toxicities and the palliation rate was 83% (complete and partial). Only five patients had no meaningful palliation having completed all three phases. Median duration of local control was 6 months (range: 1–63 months) and median overall survival was 8 months (range: 1–68 months). In five patients, the control was durable with no recurrence at the time of analysis with survival ranging from 6 to 57 months.
We are the first UK centre to report with long-term data, the use of a palliative three phase regime that provides meaningful palliation with acceptable toxicities. In addition, for some patients, it has resulted in durable long-term control.
