Aggressive surgical management of pyriform sinus carcinoma. A 15 year experience.
A total of 51 patients with pyriform sinus carcinoma were treated surgically. Fifty had pharyngolaryngectomy and radical neck dissection and 1 had a pharyngolaryngectomy. The surgical mortality was zero. No patients were lost to follow-up and all were followed for a minimum of 2 years. Stage IV patients had a 2 year survival rate of 15 percent and stage III patients, a 45 percent rate. Eighty-four percent of radical neck specimens contained involved nodes. The 2 year survival rates correlated with the number of pathologically involved nodes were as follows: 50 percent for those with zero to one node, 31 percent for two to three nodes, and 16 percent for four or more nodes. Perioperative radiotherapy increased the survival rate in those patients with zero to three involved nodes (47 percent survival rate with radiotherapy versus 25 percent without radiotherapy). Tumor recurrence was most frequent at the primary site (32 percent) and directly affected survival and control of disease elsewhere. Pyriform sinus carcinoma often presents with advanced local and nodal disease. Local control is essential, and adequate resection may require a cervical esophagectomy. Survival may be enhanced by the addition of radiotherapy in those patients with minimal nodal involvement.
