Abstract
Dichloromethotrexate, a dihalogenated analog of methotrexate, is excreted and metabolized by the liver; therefore, blood levels are not dependent on renal function. The possibility that dichloromethotrexate could be given at its maximally tolerated dose in combination with high-dose cisplatin has been evaluated in 30 patients with advanced squamous cell cancer of the head and neck. Overall, this regimen was well tolerated, and 13 of 24 evaluable patients had an objective response to therapy (25% complete response and 29% partial response). The maximum dose of dichloromethotrexate that could be delivered was related to the serum albumin. Patients with an albumin less than 3.8 g/100 mL rarely tolerated doses of 500 mg/m2 or greater. Cisplatin plus dichloromethotrexate is an active drug combination in squamous cell cancer of the head and neck, and deserves further evaluation in randomized studies and in an adjuvant setting.
