CORRELATION IN THE TREATMENT OF CANCERS OF HYPOPHARYNX AND CERVICAL ESOPHAGUS

A total of 211 cases of hypopharyngeal and cervical esophageal cancers treated in our clinic in the past 15 years were studied on their oncological characteristics such as typical pattern of the submucosal invasion, the incidence of neck metastasis and the treatment modality for recurrent laryngeal nerve (RLN) paralysis. Conclusions were as follows：1) Hypopharyngeal cancer has a tendency to invade upward to the oropharynx, and must be resected at the level just inferior to the palatine tonsil with a safety margin more than 2cm, while cancers in the post cricoid or in the cervical esophagus seem most likely to invade downward and may have skip lesions in the lower esophagus, and total resection must be indicated. 2) Bilateral neck dissection is the modality of choice because of high incidense of contralateral neck metastasis. 3) Aspiration of food and phonatory problems due to unilateral RLN paralysis can be treated with Silicone injection, while laryngeal dysfunction due to bilateral RLN paralysis can well be managed by T-tube associated with one way valve.
