title: Phase I study of thymidine (dThd) and cisplatin (DDP) given in combination.
abstract: Twenty-three patients with a variety of solid tumors were given thymidine (dThd) at a single dose of 30 g/m2 along with cisplatin (DDP) at escalating doses ranging from 25 to 120 mg/m2. The dThd was administered first, and then after 50% of the total dThd dose had been infused over 1 h, the remaining 50% was given simultaneously with DDP at a separate intravenous site over the next 2 h. Treatment was repeated at 3-week intervals. Gastrointestinal toxicity was dose-limiting and dose-related with increasing dosages of DDP. Central nervous system manifestations occurred in 17% of the patients. Mild myelosuppression was observed only at DDP doses of greater than or equal to 75 mg/m2. Thrombocytopenia was more severe than leukopenia. The maximum tolerated doses on this schedule were 30 g/m2 of dThd and 100 mg/m2 of DDP.
