title: [Combined radiotherapy and chemotherapy for head and neck cancer].
abstract: There are 4 modalities of combined radiotherapy and chemotherapy which include (1) concurrent radiotherapy and chemotherapy, (2) sequential use of radiotherapy and chemotherapy (pre-radiation chemotherapy), (3) pre-radiation chemotherapy followed by concurrent radiation and chemotherapy, and (4) alternating use of radiotherapy and chemotherapy based upon Looney's hypothesis. We studied concurrent use of radiotherapy and UFT by means of animal experimentation and clinical trials. The results obtained revealed that UFT was a most suitable agent together with 5-fluorouracil for concurrent application of radiotherapy and chemotherapy. Neoadjuvant chemotherapy including pre-radiation chemotherapy was also studied in cases of maxillary sinus carcinoma and nasopharyngeal carcinoma. From the results, it seemed desirable to use cisplatin and bleomycin analogs sequentially in combined chemotherapy and radiotherapy. Neo-adjuvant chemotherapy should be studied successively to improve local tumor control rates and prevent distant metastases. For future perspectives, new trials of alternating radiotherapy and chemotherapy based upon Looney's hypothesis seem necessary.
