Conclusion: Organ preservation surgery with partial pharyngectomy preserving the larynx is feasible for the treatment of advanced hypopharyngeal cancer with comparable local control and preservation of function. Objectives: To examine the feasibility and therapeutic effects of organ preservation surgery for advanced hypopharyngeal cancer. Methods: Fourteen patients with stage III/IV hypopharyngeal cancer were treated by partial pharyngectomy with or without partial laryngectomy to preserve the larynx. Ten cases were T1/2 primary while four cases had T3/4 tumors. Reconstruction of the pharyngolarynx was completed by primary mucosal suture in six, while free forearm flap was used in eight cases. Induction chemotherapy was administered for six cases including three with T3/4 tumors. Results: Five-year overall survival and disease-specific survival rates were 57.1% and 66.7%, respectively. The 5-year locoregional control rate was 66.7% and the larynx preservation rate was 100%. No patients presented with local recurrence at the pharyngolaryngeal segment, while two cases showed nodal recurrence, from which they died. Tracheal stoma was closed in 9 of 14 cases. Vocal function was excellent in five cases, moderate in five, and poor in three. Swallowing function was excellent to moderate in eight cases and poor in six. [ABSTRACT FROM AUTHOR]
