[2d interim evaluation of a chemotherapy study on patients with squamous cell carcinomas of the head-neck area. A comparison of 2 therapy regimens: cis-diamminedichloroplatinum (II) and bleomycin versus methotrexate and vindesine]

Abstract

52 patients with epidermoid cancer of the head and neck region were either treated with cis-DDP and bleomycin (arm A) or with methotrexate and vindesine (arm B). In case of resistance patients were further treated with the alternative regimen (A leads to B or B leads to A). Treatment results are superior in arm A. Complete and partial remission were in A: 54%, in B: 31%, after crossover 46% and 0%, respectively. Status of pretreatment (operation and/or radiotherapy) is of minor importance for arm A than for the "soft" treatment of arm B. Preliminary analysis of survival and remission duration shows no significant difference in regard to A or B and status of pretreatment. However, those patients resistant to B and further treated with A have an increase of median survival from 3 to 9 months (p = 0.02). With primary chemotherapy inoperable tumors can be made operable with curative intention.
