[Results of combined therapy of irradiation and intra-arterial one-shot injection of cisplatin for head and neck cancers].

Thirty-six previously untreated cases of head and neck cancer were given a combined therapy of irradiation and intra-arterial, one-shot injection of Cisplatin. As a result, the primary lesions in 35 cases were seen to achieve a 66% complete remission (CR) and a 100% overall response (OR). The lymph metastases in twenty-one cases with positive node achieved a 62% CR and a 100% OR. Good, local control of supraglottic and hypopharyngeal cancers were found to be an advantageous factor considered from the standpoint of the "quality of life". The cumulative survival rate, using Kaplan-Meier's method, was 82% for the first year, and 62% for the second year. No severe side effects were observed.
