Natural interferon-alpha alone and in combination with conventional therapies in non-small cell lung cancer. A pilot study.

Fourteen previously untreated patients with non-small cell lung cancer (NSCLC) were treated with natural interferon-alpha (IFN) in combination with conventional therapies. The planned dose of IFN was 6 x 10(6) IU/d.i.m. 5 days a week for 12 weeks. After 12 weeks of IFN monotherapy patients with M0 disease underwent twice-daily fractionated radiotherapy (RT), 55 Gy/4F/30 d, while IFN continued. Patients with M1 disease received 3 cycles of chemotherapy (CT) concomittantly with IFN. CT consisted of cisplatinum (P) 90 mg/m2 i.v. on days 1, 28, and 56 and of vindesine (VDS) 3 mg/m2 i.v. once a week 5 times and every other week thereafter for up to 8 courses. Thirteen patients were evaluable for response and toxicity. There were 9 patients with epidermoid, 3 with adeno- and one with large cell carcinoma. In 12 of 13 patients, the disease remained stable for 1 month during IFN monotherapy and one acheived a minimal response, which lasted 4 weeks. Of seven patients who completed the 12-week course of IFN monotherapy, 4 achieved stable disease (SD) and 3 had progressive disease. Three patients received RT and one received CT in combination with IFN as their subsequent treatment. There were 3 partial responses (2/3 after RT + IFN, 1/1 after CT + IFN), and 1 SD. Fatigue and weight loss were the most severe side-effects during IFN monotherapy. The combination of IFNs with conventional therapies might be clinically useful. We recommend further testing in larger studies.
