[Combination chemotherapy with cyclophosphamide, adriamycin, cisplatin, nimustine(ACNU), and methotrexate (EACAM) in advanced adenocarcinoma of the lung].

Twenty-two patients with advanced adenocarcinoma of the lung were treated with the combination chemotherapy "EACAM" consisting of cyclophosphamide (333mg/m2 X 1), adriamycin (27mg/m2 X 1), cisplatin (25mg X 5), nimustine (33mg/m2 X 1), and methotrexate (27mg/m2 X 3). This regimen was repeated once every 4 or 5 weeks. One complete response (CR) and 8 partial responses (PR) were obtained in 21 evaluable patients and the response rate was 42.9%. It has not been possible to calculate the median survival time for all of the evaluable cases, since 13 of them are still alive up to the present time. The side effects observes were as follows: nausea and vomiting (81.8%), alopecia (81.8%), stomatitis (22.7%), leukocytopenia less than 2,000/mm3 (45.5%), and thrombocytopenia less than 5 X 10(4)/mm3 (18.2%). Apart from strong myelosuppression, no severe infection or bleeding tendency was noticed. A mild elevation of serum createnine was observed in one patient, and no patients developed renal insufficiency. The combination chemotherapy "EACAM" is therefore considered to be a very effective and tolerable treatment for adenocarcinoma of the lung.
