Two randomized trials for alternating polychemotherapy of small cell lung cancer.
Patients with small cell carcinoma of the lung (SCCL) were treated in two multicenter trials with different cytostatic drug regimens including ifosfamide. In the first randomized study, including 306 patients, alternating chemotherapy with VP 16, ifosfamide, vindesine (VPIV), adriamycin, cisplatinum, vincristine (APO), and cyclophosphamide, methotrexate, CCNU (CMCC) was compared against standard treatment with ACO (adriamycin, cyclophosphamide, vincristine). It was shown that the alternating therapy resulted in a higher response rate (88% vs 78%) and a longer median survival time (11 months vs 10 months). Regarding toxicity, VPIV was similar to ACO, whereas APO and CMCC had more side-effects, leading to an increase in the number of drop-outs. In the second randomized study 144 patients were treated either with ifosfamide/VP 16 (IVP) or with cisplatinum/VP 16 (PVP). In the case of no further response, no change, or progression the induction therapy was changed to ACO. Interim analyses show that both regimens have similar therapeutic effects; but higher toxicity was observed in patients treated with cis-platinum/VP 16 than in patients treated with ifosfamide/VP 16. According to the response rate in patients treated with ACO after first-line therapy there was less cross-resistance of IVP than of PVP to ACO.
