OBJECTIVE To evaluate the treatment results of perioperative radiation and conservation laryngeal surgery for advanced hypopharyngeal cancer. METHODS Forty seven patients with hypopharyngeal cancer treated with laryngeal function-sparing surgery were collected in this retrospective study. There were 3 posterior hypopharyngeal wall cancers and 44 pyriform sinus cancers. Forty four patients received preoperative irradiation,and three postoperatively. The types of surgery were:21 pyriform sinusectomies,16 pyriform sinusectomies accompanying with partial laryngectomies,and 10 partial hypopharyngectomies with near total laryngectomies. Six skin flaps and 2 jejunum flaps were used to repair the defects. RESULTS The 5 year survival rate of Ⅲ,Ⅳstage was 59 % and 50.2 % respectively and the laryngeal functions were preserved. CONCLUSION The policy of laryngeal function preservation was feasible in the treatment of locally advanced hypopharyngeal cancer. Suffice it to say that a combination of radiation and surgery was mandatory

Objective: To discuss the strategy of therapeutic management of T3 supraglottic carcinoma. Methods: A retrospective analysis of 459 patients with T3 supraglottic carcinoma treated in our hospital was performed. We evaluated the results of different managements, including surgery alone, preoperative radiotherapy, postoperative radiotherapy and radiotherapy alone. The extent of the lesion was also put into analysis. Statistical analysis of the overall survival (OS), cause-specific survival (CSS), local control (LC), regional control(RC), function-conservation (FC) were performed with the statistical package from SPSS. Results: In all patients, the rates of 5-year OS, CSS, LC, RC and FC were 64.2%, 71.2%, 87.8%, 78.8% and 64.5% respectively. The OS, LC and FC of the patients treated by surgery alone, preoperative radiotherapy and postoperative radiotherapy had no significant difference, and were remarkably better than that of patients treated by radiotherapy alone (P<0.001). In 412 patients treated by surgery, 300 patients received function-conservation laryngectomy. 209 patients (50.7%, 209/412) survived and maintained well-function of larynx for 5 years, which was significantly better than those in the radiotherapy alone group (27.7%, 13/47). The patients with the lesion invading the pre-epiglottic space but limited in supraglottic area had better OS (70.2%), LC (93.5%) and FC (85.1%). The rate of 5-year neck lymphatic metastasis was 56.2%(258/459), and the 5-year OS of patients with N0, N1, N2 and N3 stage were 76.0%, 66.2%, 50.5% and 13.0% respectively. Conclusions Surgical treatment was the best therapeutic approach for T3 supraglottic laryngeal carcinoma. Most patients with T3 lesions are suitable for function-conservation laryngectomy. Surgical procedure was determined by tumor invaded location and extension. The combined therapy of surgery and radiotherapy had no significant advantage.
