Comparative evaluation of two administration schedules of cis-dichlorodiammineplatinum (DDP) in ovarian and head and neck cancers: a CMEA chemotherapy group study.

The therapeutic effectivity of two administration schedules of DDP were compared. The dose was either 100 mg/m2 infused for 4 h or 20 mg/m2 infused for 1 h on 5 consecutive days. The combined objective remission rate of the two regimens were 37/53 (23% CR ++ 44% PR) for ovarian cancer and 8/35 (9% CR + 14% PR) for head and neck cancer. WHO Grade 1-2 myelo- and nephrotoxicity was observed in 26% and 20%, respectively, out of the 105 cases evaluable for toxicity in the two groups. Nausea and vomiting was moderate to severe. Neither the remission rate nor the toxicity of the two schedules were significantly different.
