Results of radiotherapy with, or without, salvage surgery versus combined surgery and radiotherapy in advanced carcinoma of the hypopharynx

There is considerable controversy surrounding the optimum treatment of advanced hypopharyngeal cancers. Curative radiotherapy with surgical salvage in reserve is an accepted protocol as is also a combined treatment of surgery and radiotherapy. The present study is a retrospective analysis of the survival results of 195 cases treated in a single centre. The combined surgery and radiotherapy group comprised a greater number of pyriform fossa and post-cricoid tumours whereas, the curative radiotherapy group had a higher proportion of posterior pharyngeal wall tumours. Actuarial two-year disease-free survival rates were significantly better with combined treatment when results of stage III and IV lesions (164 patients) of all sites are taken together, as compared to those obtained with curative radiotherapy without salvage (p = 0.000) or radiotherapy with surgical salvage for residual/recurrent tumours (p = 0.0021).
