title: Larynx preservation surgery in pyriform sinus cancer.
abstract: As a general rule, surgery, whenever possible followed by irradiation, is considered to be a standard treatment for pyriform sinus cancer. In early primary lesions, many different approaches have been tried for larynx preservation. From 1990-1997, 7 patients with pyriform sinus carcinoma without the involvement of pyriform sinus apex were treated with partial laryngopharyngectomy at the Asan Medical Center. Three patients were T1 stage and four were T2. All patients had nodal metastases and were treated with neck dissection and postoperative radiotherapy. Follow-up period was 1-8 years. One regional recurrence and one distant metastasis occurred; however, there was no recurrence at the primary site. The voices of all the patients were saved. The most uncomfortable postoperative symptom was mild aspiration. From these results, we can conclude that partial laryngopharyngectomy with neck dissection might be the favorable treatment modality for selected cases of pyriform sinus cancer.
