Abstract
The results of treatment with 5-fluorouracil, imidazole carboxamide, BCNU and prednisolone (FIB-P) salvage chemotherapy in 60 patients with heavily pretreated advanced breast cancer are presented. For most of the patients (82%) this was the third line of chemotherapy. Performance status (ECOG) was 1, 2 and 3 in respectively 13, 27, and 20 patients. Predominant metastatic sites were: soft tissue (3/60, 5%), bone (22/60, 37%), and viscera (35/60, 58%). Tumor burden (number of affected organic systems) was 1, 2 and 3 or more in respectively 18, 24 and 16 patients. Average dose intensity received was 0.74 (range, 0.47–0.98); the average number of cycles was 3.8 (range, 2–8). Objective response (CR + PR) was observed in 22 patients (1 CR, 21 PR), with a response rate of 37% (22/60). Median duration of remission was 7 months (range, 3–15). Tumor burden was the only pretreatment patient characteristic that significantly influenced the remission rate (p < 0.10). Dose intensity significantly affected tumor response (p < 0.05). Toxic side effects (gastrointestinal disorders, alopecia and myelotoxicity) were generally moderate and tolerable. No treatment-related death occurred. FIB-P proved to be an active salvage chemotherapy in heavily pretreated patients with advanced breast cancer.
