title: [Etretinate (Ro 10-9359, Tigason) and CCNU (1-(2-chloroethyl)-3-cyclohexyl-l-nitrosourea) and bleomycin versus CCNU and bleomycin in the treatment of advanced squamous cell carcinoma of the bronchus (Working group on Internal Medicine Oncology Study BS1/78)].
abstract: Forty-six evaluable patients with advanced squamous cell carcinoma of the lung were treated in a randomized fashion with either etretinate, CCNU and bleomycin in combination (ECB) or with CCNU and bleomycin (CB). There were no complete and no partial responses. Minor responses occurred in 5 patients (24%) with ECB and in 3 patients (12%) with CB independently of histological grade. No change was observed in 9 patients (43%) with ECB and in 13 patients (52%) with CB. There was no survival difference between the two groups. Reversible side-effects of skin and mucous membranes were more frequent under ECB. The antitumor efficacy of CB is marginal and could not be improved by the addition of the vitamin-A-derivative etretinate.
