Abstract:The aim of this study was to evaluate the results of the initial and salvage treatment for hypopharyngeal carcinoma. The study was conducted in 1963 to 1991and included 138 patients (38 females (28%) and 100 males (73%)). Most of the tumours originated in the piriform sinus (86%). Tumour stage distribution was T1: 20%, T2: 27%, T3: 37% and T4: 17% and nodal stage distribution was N0: 45%, N1: 25%, N2: 10%, and N3: 20%. Primary treatment was delivered with curative intent in 124 out of 138 cases (90%). Treatment failure was noted in 98 patients, with 55% recurrence in T-position, 39% in N-position, and 14% at distant metastases sites. Salvage surgery was successful in 9 out of 32 patients. The overall 5-year locoregional tumour control, cause-specific and overall survival rates were 20%, 25% and 19%, respectively. Univariate actuarial analysis showed that T- and N-stage, clinical stage, tumour size and well-differentiated tumours were significant prognostic parameters. A Cox multivariate analysis showed that only the T- and N-stages were independent prognostic factors. In conclusion, the prognosis for advanced hypopharyngeal carcinoma is extremely poor and the meagre results with conventional radiotherapy alone indicate that other treatment modalities should be introduced in the management of this disease.
