[Treatment of non-Hodgkin's lymphoma with NK-631 (peplomycin)--with special reference to the effect on T and non-T cell lymphomas].
NK-631 (Peplomycin) has an anti-tumor spectrum, equivalent to or higher than its analogue bleomycin and low toxicities to the lungs. Fourteen patients with advanced non-Hodgkin's lymphoma received NK-631 10 to 30 mg once or twice a week. As the results, there were 57.1% response rate of all patients. The response rate according to the immunologic classification were 100%(6/6 cases) for patients with non-T cell lymphoma and 25%(2/8 cases) for patients with T-cell lymphoma. On the other hand, we observed some toxicities such as transient fever in 64.3%, G-I tract symptoms in 21.4%, skin toxicities in 21.4% and pulmonary fibrosis in one case. This agent is considered to be one of the useful agents to non-Hodgkin's lymphoma especially non-T cell lymphoma.
