The overall response rate was 17%, with most regressions occurring with the IFN-α2A regimens. The median times to progression (1 month) and survival (6 months) were generally similar to those from chemotherapeutic agents. However, a limited cohort of patients had complete regressions or durable partial responses even after treatment was discontinued or maintained at ≤25% of the starting dosage. Most objective regressions were partial, occurred in nonvisceral sites, and were detected within 2 months of the beginning of therapy. The most noteworthy sequelae from these regimens were predominantly constitutional, but without any obvious long-term complications. These interferon programs can be conveniently self-administered on an outpatient basis. Although single-agent interferon regimens for advanced malignant melanoma will probably not offer a substantive therapeutic advance, combinations of these molecules with other biological agents (tumor necrosis factor), biochemical modulators (difluoromethylornithine), and cytotoxic agents (bischloro-ethylnitrosourea, BCNU) offer innovative therapeutic dimensions in the design of future clinical investigations.
