Management of locoregional recurrent oropharyngeal carcinoma.

Sixty-seven patients with recurrent locoregional squamous cell epithelioma of the oropharynx were reviewed to determine the curative potential of secondary therapy for recurrent carcinoma. Of the 37 patients in whom recurrent carcinoma developed after radical surgery, only 11 percent (4 of 37) had a 2 year disease-free survival following secondary treatment. Recurrence developed in 30 patients after radiation therapy. Surgical resection of the recurrent carcinoma was possible in 13 of the patients, 38 percent (5 of 13) of whom were free of disease for a minimum of 2 years. Though treatment results in patients with recurrent oropharyngeal carcinoma are discouraging, secondary therapy in selected patients can yield 2 year disease survival in over a third of cases. Favorable prognostic factors included the development of recurrent carcinoma following radiation therapy and a tumor initially classified as stage I or II, irrespective of the initial mode of therapy.
