[Surgical management of hypopharyngeal cancer].

OBJECTIVE: To investigate the preservation of laryngeal function for the patients with hypopharyngeal cancer. METHODS: Two hundred and ninety-three cases of hypopharyngeal cancer with surgical management were reviewed retrospectively, and 222 cases were originated from pyriform sinus, 13 from post-cricoid, and 21 from posterior pharyngeal wall. Radiotherapy (37 cases), operation only (56 cases) and the combined treatment (operation plus radiation or chemotherapy, 200 cases) were adopted. 159 cases were treated with function preserved laryngectomy and 97 with total laryngectomy. RESULTS: The 5 year survival rates of patient with laryngeal function preserved and no laryngeal function preserved were 51.3%, 47.6% (for stage III); 40.4%, 43.3% (for stage IV), respectively. There were no significant differences in 5-year survival between the functionally preserved group and no functioned group (P > 0.05). The analysis of survival rates revealed a significant difference between combined therapy and radiotherapy. CONCLUSION: There is no significant difference between the survive rates of function preserved and non-preserved groups. Conservation laryngectomy improves the quality of patient's life, and combined therapy is the best choice for hypopharyngeal cancer.
