From November 1993 to December 1994, a prospective multi-centre phase II clinical trial was done in 137 patients with advanced cancer on China-made pepleomycin (PEP). PEP was effective in patients with cancer of the head and neck, malignant lymphmo and lung cancer, with response rate of 66.7%, 50% and 30%, respectively. The major adverse reactions were fever and mild gastrointestinal reaction. In the controlled study of combination chemotherapy with China-made and Japan-made PEP, the response rates and side effects were similar. The results indicate that China made PEP can be used in lieu of that made in Japan.
