Cancer of the hypopharynx. Analysis of treatment and results in 162 patients.
Between 1962 and 1972, 190 patients with squamous cell carcinoma of the hypopharynx were seen; 162 received primary treatment at our clinic. Of the 162 lesions, 117 (72%) originated in the pyriform sinus. The most frequent symptom was pain in the throat (87 patients, 54%). One hundred twenty six patients (78%) had tumors extending beyond the hypopharynx (T3 lesions), and 108 patients (67%) had cervical metastasis (stage III or IV). Treatment modalities included surgical excision in 82 patients, radiation in 39, planned combination of preoperative radiation followed by surgery in 18, radiation plus neck dissection in 15, and surgery plus postoperative radiation in eight. Sixty-nine patients (43%) had recurrent tumor. Recurrences were equally frequent in the primary site and the neck. Comparison of treatment modalities showed no differences in overall recurrence. Surgery alone or in combination with radiation reduced the incidence of local recurrence; however, when recurrences were analyzed in relation to stage of lesion, preoperative or postoperative radiation and surgery offered no advantage over surgery alone in reducing local or neck recurrence or in overall survival rate. Treatment by radiation alone was associated with a poorer survival. For the entire group, three-year survival was 52% and five-year survival was 47%.
