[Head and neck cancer].
Phase II study of nedaplatin (NDP), a new derivative of cisplatin, was completed in 1990, so this agent is now commercially available. NDP is very effective for head and neck cancer. Out of the 90 evaluable patients, CR was achieved in 11 patients and PR in 27 with a response rate of 42%. A new combination chemotherapy containing NDP, especially NDP + 5-FU, was clinically tried. Furthermore concurrent NDP and radiotherapy will be tried in the near future. Phase II study of S-1 (tegafur + CDHP + Oxo) and taxotere (TXT), however, is ongoing. The results obtained so far are almost satisfactory. The aouthor also adopted several new agents which were presented at the ASCO meeting (1993-1997): taxol (TXL), taxotere (TXT), topotecan, amonafide, vinorelbine and thymitaq. Response rates of these agents were as follows: TXL: 26-37%, TXT: 27-41%, topotecan: 0-27%, vinorelbine: 6.7-12.5%, thymitaq: 18.2% and amonafide: 3.6%. So TXL and TXT are very effective for head and neck cancer. In terms of combination chemotherapy, response rates are 33-71% in TXL + CDDP, 23-62% in TXL + CBDCA, 78% in TXT + CDDP and 75% in TXT + CDDP + 5-FU. Concurrent radiotherapy and chemotherapy including new agents are interesting and important issues. Two kinds of protocol were adopted, 5-FU + HU + TXL + RT and TXL + CBDCA + RT. Both protocols are responsive to squamous cell carcinoma of the head and neck. But severe local toxicity (stomatitis) and bone marrow suppression pose problems.
