Abstract:
Twenty-two patients with advanced malignancies were treated with low-dose cytosine arabinoside (ara-C) (45 mg/m2 sc every 12 h for 3 days) and cisplatin (DDP) (100 mg/m2 ev on day 2, 2 h after ara-C. Patients received 61 cycles of ara-C + DDP with a median number per patient of 2.7 cycles (range, 1-5). All patients were evaluable for toxicity and response. Overall, 6 of 22 patients (27%) obtained an objective response (2 CR + 4 PR) with a median response duration of 20 weeks. Hematologic and gastrointestinal toxicities were moderate. Our results show a low response rate with the ara-C and DDP combination compared to the interesting results obtained in vitro.
