[Combination of cisplatin-mitomycin-vindesine for inoperable, non-small-cell bronchial cancers. French study group in pneumo-cancerology].

The efficacy of the association of cisplatinum-mitomycine and vindesine on inoperable non-small cell bronchial cancer has been assessed in a prospective study. Cisplatinum 120 mg/m2 and mitomycine 8 mg/m2 on day 1, day 28 and day 70, and vindesine 3 mg/m2 once per week for the first cycle, once every 15 days for the second and third cycles. 98 patients were included in the study between February 1989 and June 1990: there were 89 men and 9 women with a mean age of 60. There were 57 epidermoid cancers, 22 adenocarcinomas, 1 neuroendocrine carcinoma and 18 large cell cancers. There was an objective response (RO) in 25% (of whom 5% had a complete response) without any significant difference between the 56 cancers at stage III (32% RO) and 42 cancers in stage IV (17% RO). The median survival of the responders was 14 months again 5 months for the non-responders. The initial loss of weight seemed to be a prognostic factor because the number of objective responders was significantly greater in the patients with only a small weight loss: 37% of RO if the weight loss was less than 5%, against 11% for a weight loss of greater than 5%. The myelotoxicity of this association was important because 85% of those patients presented with a leucopenia at least grade II OMS. Peripheral neuropathies occurred in 27% of cases: 4 cases of cardiotoxicity were reported.
