Abstract
We have performed transoral surgical resection for patients with T1/T2 hypopharyngeal cancer and induction chemotherapy with docetaxel for patients with T2/T3 disease. The patients were analyzed in order to determine the current situation of larynx preservation in patients with hypopharyngeal cancer. The data of a total of 83 patients with hypopharyngeal cancer were analyzed retrospectively. The primary subsites were : pyriform sinus (PS) in 61 patients, posterior wall (PW) in 13 patients, and postcricoid (PC) in 9 patients. The number of patients classified as having T1, T2, T3 and T4 disease were 14, 29, 23 and 17, respectively. The main therapies employed in the patients were as follows: transoral surgical resection plus radiation therapy for T1 disease, radiation therapy, induction chemotherapy, and partial resection for T2 disease, induction chemotherapy, radiation therapy, and pharyngo-laryngoesophagectomy for T3 disease, and pharyngo-laryngoesophagectomy plus induction chemotherapy for T4 disease. The 5-year larynx preservation rates in the patients with T1, T2, T3 and T4 disease were 100%, 73%, 39% and 35%, respectively. Our method was able to improve the larynx preservation rate without having any adverse effect on the survival rate. However, the strength of treatment for T 3 disease needs to be improved, because a large number of recurrences and deaths due to the primary disease were encountered in this patient group.
