Phase II study of alpha-interferon plus bleomycin in advanced non-small cell lung cancer.

Overview

A synergistic effect between alpha-Interferon and Bleomycin has been recently shown in in vitro and in vivo experimental systems. Although active, Bleomycin and other antineoplastic drugs give low response rates in non-small cell lung cancer, but, like the other antineoplastic agents, responses are short-lived. We treated 13 patients with advanced non-small cell lung cancer with the combination Bleomycin 15 mg/m2 i.v. at hour 0 and alpha-Interferon 9 X 10(6) U i.m. given at hours 6, 30 and 54. Major side effects were pyrexia, astenia and anorexia; only one case of moderate leukopenia was observed. No major responses were obtained and stable disease lasted a median of 5 months. Further study of this combination is not warranted in patients with pretreated non-small cell lung cancer.
