Problems in the treatment of carcinomas in the hypopharynx and cervical esophagus were discussed. For complete resection of carcinomas, safety margins should be decided by careful consideration of the extent of submucosal invasion that varies primarily because of differences in directional preponderance of submucosal lymphatic drainage in each region. Bilateral neck dissection should be performed because of the high incidence of metastasis to regional nodes. Postoperative irradiation and maintenance chemotherapy were stressed as indispensable.
