Phase I study of carboplatin, irinotecan and docetaxel on a divided schedule with recombinant human granulocyte colony stimulating factor support in patients with stage IIIB or IV non-small cell lung cancer.

A phase I study was conducted to determine dose-limiting toxicity (DLT) and maximum tolerated dose (MTD) of carboplatin combined with irinotecan and docetaxel on a divided schedule with recombinant human granulocyte colony stimulating factor (rhG-CSF) support in patients with stage IIIB or IV non-small cell lung cancer. Carboplatin was given at the dose of AUC5 on day 1. Irinotecan and docetaxel on days 1 and 8 were administered at a starting dose of 40 and 30 mg/m2 as level 1.
