Cisplatin, doxorubicin, cyclophosphamide, and vindesine combination chemotherapy for non-small cell lung cancer.

Seventy-four patients with non-small cell lung cancer were treated in a prospective, randomized trial either with a four-drug combination of cisplatin, doxorubicin, cyclophosphamide, and vindesine (PACE) or with a three-drug combination of cisplatin, cyclophosphamide, and vindesine (PCE). None of these patients had received prior chemotherapy, and all had a Karnofsky performance status of at least 60. Of 68 evaluable patients, 21 (31%) had complete or partial remissions. Response rates for PACE and PCE were similar, and there was no difference in response rates for patients with adenocarcinoma or epidermoid cancer. The median duration of remission was 10 months (range, 2-26+); five patients are still in remission (median, 18+ months; range, 17+ to 26+). The median duration of survival for responding patients (complete or partial) was 18 months. Toxic effects, including mild to moderate myelosuppression, peripheral neuropathy, and nephrotoxicity, were manageable in general. The response rates and remission durations for PACE and PCE are similar to those seen with the two-drug combination of cisplatin and vindesine, and toxic effects are similar. Thus, the addition of doxorubicin and/or cyclophosphamide adds no advantage to the use of the cisplatin and vindesine combination alone.
