Squamous cell carcinoma of the pyriform sinus.
At the Roswell Park Memorial Institute, 111 patients were treated for squamous cell carcinoma of the pyriform sinus over a 15-year period. Treatment modalities included surgery, radiation therapy, or a combination of both. A retrospective study was carried out to determine how these treatments, used singly or in combination, affected the cure rate. TNM clinical staging and recurrence patterns were studied, and a high tendency for distant metastases was documented. The five-year survival figure in this study was 29% (28/97).
