The role of combination chemotherapy in the treatment of advanced non-small-cell lung cancer is controversial. At best, a small survival benefit can be achieved. Therefore, other treatment modalities are needed. On the basis of the promising treatment results with interleukin-2 (IL-2) -containing immunotherapy in renal cell cancer and melanoma, we performed a phase I-II study with IL-2 and interferon alpha (IFN-alpha). Eligible patients were treated with IL-2 18 x 10(6) IU/m2/day by continuous intravenous infusion (c.i.v.) for 3 days. On the same days, 5 x 10(6) U/m2/day IFN-alpha was given intramuscularly. After a rest period of 4 days, patients at the first dose level received IL-2 2.4 x 10(6) IU/m2/day c.i.v. for a period of 28 days, followed by 14 days' rest, 14 days' treatment, 7 days' rest, and a final treatment for 14 days. Patients at the second dose level were treated according to the same schedule, in which the dose of IL-2 was increased to 3.6 x 10(6) IU/m2/day. During low-dose IL-2 treatment, patients received IFN-alpha 5 x 10(6) U/m2/day on days 1 and 4 of each week. Eleven patients were admitted to the study, six at the first and five at the second dose level. Median age was 54 years; all patients had a performance status of 0 or 1. The most important adverse effects included anorexia, fatigue, nausea, and headache, which were not dose limiting. In the 11 patients treated, no responses were seen. Nine patients developed progressive disease during the first 5 weeks of treatment. We concluded that this regimen of IL-2 and IFN-alpha is ineffective.

We have reported that increasing the length of infusion from 5 min to 1 h appeared to substantially reduce the toxicity associated with fluorouracil (5-FU) modulated by leucovorin (LV) and interferon alpha-2a (IFN-alpha). This phase II study assessed the antitumor efficacy of this regimen. Patients (n=38) with colorectal cancer received IFN-alpha 5 MU/m(2) SC on days 1-6; on days 2-6, LV 200 mg/m(2) IV was given with 5-FU at initial doses of 370-425 mg/m(2)/h. The regimen was well-tolerated with no grade 4 toxicity. At 425 mg/m(2) 5-FU, grade 3 toxicities included diarrhea (8.6%), anorexia, fever and fatigue (5.7% each), neutropenia and nausea/vomiting (2.9% each). Individuals tolerated 5-FU doses up to 644 mg/m(2). Objective responses occurred in 27% of 37 patients; median time to progression and survival were 6.1 and 12.9 months. Only 1 of 25 informative tumor samples had high-frequency microsatellite instability (MSI), while 7 of 23 assessable patients (30%) with MSI-negative tumors had an objective response. With 425 mg/m(2), the average 5-FU Cp and AUC(0-1 h) were 37.4 microM and 1161 microM/h. Some 6 patients had extended sampling, and the half-lives of 5-FU and FBAL (apparent) were 8.6 and 100.0 min, respectively. A 1-h infusion of 5-FU is well tolerated; individual dose escalation of 5-FU allows each patient to receive the maximum tolerable dose.
