Biweekly docetaxel-irinotecan treatment with filgrastim support is highly active in antracycline-Paclitaxel-refractory breast cancer patients.

Purpose: To evaluate the feasibility and activity of combination treatment with docetaxel (DTX) and irinotecan (CPT-11), given together every other week, combined with filgrastim support, in anthracycline- and paclitaxel-pretreated breast cancer (BC) patients.

Patients And Methods: Advanced BC patients pretreated with anthracycline- and paclitaxel-based chemotherapy were eligible. DTX (80 mg/m2) and CPT-11 (100 mg/m2) were given biweekly with filgrastim support (300 microg/day on days 4-7).

Biweekly docetaxel-irinotecan with filgrastim support in pretreated breast and non-small-cell lung cancer patients. A phase I study.

Background: Docetaxel (DTX) has been shown to be a very active drug in both breast cancer (BC) and non-small-cell lung cancer (NSCLC). Irinotecan (CPT-11) is also active in NSCLC, and has shown promising antitumor activity in pretreated BC. PURPOSE.
