Doxorubicin-hexamethylmelamine therapy of small cell carcinoma of the lung.

Eighteen patients with small cell carcinoma of the lung treated with doxorubicin hydrochloride and hexamethylmelamine are presented. Fifteen of these patients had extensive disease at presentation. Four patients in this group died after one or fewer courses of chemotherapy. The median duration of survival for the entire group of patients is 15 months. Six patients are alive from 18 to 56 months without evidence of disease. Drug toxicity was minimal and well tolerated, which permitted this regimen to be given in an outpatient setting.
