Randomized controlled study of adjuvant immunotherapy with Nocardia rubra cell wall skeleton for inoperable lung cancer.

Abstract

In order to evaluate the clinical benefit of Nocardia rubra cell wall skeleton (N-CWS), a randomized controlled study was performed with inoperable lung cancer patients entered in 5 institutions from October 1978 to June 1981. Patients without pleural effusions were treated initially with conventional therapies such as chemotherapy and/or radiotherapy, according to common protocol, and then patients in performance statuses 0 to 3 were randomized into control and N-CWS groups with stratification into 16 categories according to 4 histological types and 4 clinical stages In the N-CWS group, 400 micrograms N-CWS were initially injected once or twice into the bronchial tumor using a fiberoptic bronchoscope, and subsequently 200 micrograms of N-CWS were injected at monthly intervals into the skin from the shoulders to upper arms. Of 309 patients, 118 patients in the N-CWS group and 108 patients in the control group were eligible for statistical analysis. There was statistically no significant difference in survival rate between the control and the N-CWS groups. According to histological type, significant prolongation of the survival period was observed in patients with small-cell carcinoma. The 97 patients with pleural effusions were initially randomized into control and N-CWS groups. In the control group, local chemotherapy with Adriamycin was performed and, in the N-CWS group, local administrations and monthly intracutaneous injections of N-CWS were given. Tube thoracostomy was performed in both groups. The local response rate was statistically greater in the N-CWS group than in the control group, and survival period was also prolonged significantly in the N-CWS group. The main adverse reactions to N-CWS were skin lesions in the injected sites and fever, but these were temporary and not serious.
