Adjuvant therapy with low-dose interferon-beta for stage II and III melanoma: results of a retrospective analysis

Summary

Interferon (IFN)-alfa as an adjuvant therapy has been found to improve relapse-free survival in patients with malignant melanoma (MM). However, the efficacy of IFN-beta has not been studied in detail. This study evaluated the contribution of adjuvant IFN-beta therapy to improvements in the prognosis of patients with MM. We reviewed 63 patients with resected stage II/III primary MM at our institution. Of these, 36 had been treated with IFN-beta adjuvant therapy (subcutaneous injection, 3 × 106 IU/day, 10 days), while 27 patients had undergone observation alone. In comparisons of all patients (stage II/III), overall survival and relapse-free survival were significantly better in the IFN-beta group than in the observation group (P < 0.001 for both). The 75-month overall survival rate was 41.2% in the observation group and 68.7% in the IFN-beta group. Adjuvant therapy with IFN-beta may become a new treatment option for patients with stage II/III MM.
