title: Angiogenic and immune parameters during recombinant interferon-alpha2b adjuvant treatment in patients with melanoma.
abstract: As an adjuvant therapy for patients with high risk of recurrent melanoma, high-dose interferon (IFN)-alpha2b therapy has been shown to have some efficacy. We examined 22 patients with resected melanoma who were treated with repeated injections of recombinant IFN-alpha2b during the treatment. Both angiogenic and immune parameters were measured. White blood cells (WBCs) and lymphocyte numbers, lymphocyte subpopulations, serum concentrations of IFN-alpha and anti-IFN-alpha antibodies, and the serum vascular endothelial growth factor (VEGF), interleukin (IL)-8, and basis fibroblast growth factor (bFGF) concentrations were determined over time in resected, recurrence-free patients with American Joint Committee on Cancer (AJCC) stage III melanoma with one or less (LN+ < or = 1, n = 7) or more than one (LN+ > 1, n = 8) lymph nodes involved, and AJCC stage IV resected disease (n = 7). Follow-up and recurrence-free intervals were longer in stage III (LN+ < or = 1) patients compared with stage IV patients (P < 0.05). The number of WBCs and lymphocytes decreased during the treatment for all patient groups (P < 0.001). In addition, percentages of CD8 and CD20 were higher in stage IV patients than in stage III (LN+ > 1) and stage III (LN+ < or = 1) patients at the beginning of therapy (P < 0.05). A significant increase in the percentage of CD20+ cells, mostly B lymphocytes, was observed in the stage III (LN+ > 1) and stage III (LN+ < or = 1) patients over time but not in stage IV patients (P < 0.001). Low IL-8 and bFGF concentrations at the beginning of therapy were associated with significantly longer recurrence-free survival (P < 0.05). These results warrant a larger trial to determine if the differences observed in patients before treatment can provide prognostic markers in patients receiving IFN-alpha2b therapy.
