Expression analysis of classic and non-classic HLA molecules before interferon alfa-2b treatment of melanoma

Individual predictive clinical, immunological, or molecular features for definition of patients with lymph-node-positive melanoma who do not benefit from adjuvant postsurgery high-dose interferon alpha treatment are lacking. Expression analysis of classic and non-classic HLA molecules on melanoma cells metastatic to the locoregional lymph node may help select these patients before treatment.
