Abstract
Chemotherapy of head and neck cancer has recently been receiving increasing attention as a treatment modality. The basis for this interest has been the availability of at least three agents with reproducible antitumor activity: methotrexate, bleomycin, and cisplatinum (diamminedichloroplatinum). These agents alone or in combination have been demonstrated to be of palliative value in patients whose disease recurs or is too advanced for other therapeutic modalities. Although the multiple drug regimens used have not been curative, their relative effectiveness has raised hopes that, in combination with other modalities, they may lead to improvements in survival and in local control in earlier stages of disease. In addition, as a result of multimodality approaches, it is hoped that it may be possible to identify the role of chemotherapy and specific agents in the treatment of various sites of origin of these tumors. The interaction of chemotherapy and radiation—and the use of intraarterial chemotherapy—fall beyond the scope of this review but constitute another important aspect for investigation in the treatment of these malignancies.
