title: Continuous five-drug versus alternating three-drug and two-drug chemotherapy after five-drug or three-drug induction in extensive small cell lung cancer.
abstract: Fifty-six patients with extensive small cell lung cancer were treated with vincristine, doxorubicin, cisplatin, etoposide, and cyclophosphamide in a prospective randomized trial using all five drugs together or as three-drug (cisplatin, etoposide, cyclophosphamide) and two-drug (doxorubicin, vincristine) combinations given sequentially, then alternatively. The five-drug combination was associated with a higher overall regression rate (p = 0.03), higher complete regression rate (p = 0.09), prolonged time to first progression (p = 0.03), more nervous system initial failures (p = 0.07), more anemia requiring transfusion (p = 0.04), but no prolongation of overall survival (median 332 days for five-drug, median 303 days for three-drug and two-drug). Until more and better chemotherapeutic agents become available, little or no advantage is likely to be gained for patients with small cell lung cancer given sequential, or alternating chemotherapy.
