We had 31 patients(8 males and 23 femals)with postcricoid carcinoma in the period from 1978 to 1988.This number of patients correspond to about 15.3% of patient with hypopharyngeal carcinoma we encounterd in this period.There were 4 patients in the condition Stage I, 8 in Stage II, 7 in Stage III and 12 in Stage IV.Most of these patients underwent radical surgery.5-year cumulative survival rate was 46.8%(Kaplan-Meier).The cause of death was neck metastasis in 75% of patients who died of postcricoid carcinoma.There was a significant difference in survival curve between patients with neck metastasis and patients free from it(5-year cumulative survival rate was 68.0% and 16.7%, respectively;p<0.01).Neck metastasis was noted in the paratra- cheal region in 29.0% of patients.In patients with primary tumor of not larger 2.5cm(n=7), nometastasis was noted, nor recurrence in this series of patients.
