[Chemoradiation using 5-fluorouracil (5-FU) and nedaplatin (NDP) for gynecological malignancy--the relation between hemotoxicity and sequence of 5-FU and NDP].

We compared sequence-dependent schedules of 5-fluorouracil (5-FU) and nedaplatin (NDP) for hemotoxicity in genecological malignancy (GM). The safety of schedules using 5-FU before/after NDP combined radiotherapy in 8 patients with GM was evaluated. They received either 5-FU 700 mg/m2 i.v. continuous infusion on days (D) 1-4 + NDP 100 mg/m2 i.v. bolus on D1 (group A: 5 pts), or NDP on D4, 5-FU on D1-4 (group B: pts). In group A, 4 patients received a reduced dose of NDP because of less than 60 ml/min of creatinine clearance. In group A, WBC (2 pts), hemoglobin (3 pts), and platelet (1 pts) were grade 3 or higher. In group B, grade 3 or higher in hemotoxicity was not seen. A higher percentage of hemotoxicity was seen in group A compared with group B.
