Chemotherapeutic management of bronchogenic carcinoma: trials with NSC-140117, a new methanesulfonic acid ester of aminoglycol.

A new drug, NSC-140117, was used in the management of 15 patients who had late bronchogenic carcinoma and were unable to receive surgical or radiotherapeutic treatment. Good responses in the form of 90% shrinkage in the size of the lesionswere encountered in nine patients (60%). Response is still being maintained from 6 months to 1.5 years after the start of therapy. No toxic effects, including hematopoietic toxicity, were encountered.
