title: [Retrospective study of the treatment of piriform sinus cancers. Apropos of 97 cases].
abstract: Results of a retrospective analysis of case-reports of 97 patients treated for piriform sinus cancer showed a high frequency of large tumors and adenopathies providing an explanation for the very poor prognosis of these cancers. Therapy of choice for T1-T2 tumors is still radiotherapy. However, recently obtained results and data from the literature demonstrate the increased benefits of partial surgery with monoblock curettage followed by radiotherapy in cases with an ulcerous tumor, a mobile larynx and adenopathy of 3 cm or more. For T3-T4 cases the best treatment is by total pharyngolaryngectomy and postoperative radiotherapy.
