Technics and results of radiotherapy of hypopharyngeal and cervical esophageal cancer were surveyed. Remarkable improvement was found in the recent results of treatment both by radiation and surgery. Especially the combined treatment was the best in the result. Accurate treatment technics using modern supervoltage radiations enabled us to cure cases of early stage with minimum loss of function and with minimum radiation injury. Our treatment policy was as the following: T<SUB>1</SUB> N<SUB>0</SUB>; Radiotherapy is the first choice. T<SUB>1</SUB>N<SUB>+</SUB>, T<SUB>2-3</SUB> N<SUB>0</SUB> or<SUB>+</SUB>; Preoperative irradiation and surgery. Advanced cases; by radiation alone. 5 year survival rate for National Cancer Center cases were 18/63 28.5% for total cases, 18/44 41.0% for radically treated cases, 6/20 30% by radiation alone, 11/21 53% by radiation and surgery and 1/3 33% by surgery alone respectively. Certain number of far advanced cases who had extended primary and metastatic lesions including pulmonary metastasis showed surprizingly good responses to the radiotherapy and survived more than 5 years. These interesting cases highly stimulated us to consider the role of host resistance in the radiotherapy.
