Abstract

HLA phenotypes were characterized for 79 patients with metastatic renal cell carcinoma treated with interleukin 2 (IL-2). HLA-A32 was associated with a clinical response (P = 0.025). The frequency of HLA-A3 and/or A32 was higher among responders than non-responders (P = 0.008). Thus, these results suggest that, in vivo, IL-2 may enhance cellular-mediated immunity against a tumour antigen and that some MHC molecules are more efficient than others for endogenous tumour antigen presentation.

摘要

对79例接受白细胞介素2(IL-2)治疗的转移性肾细胞癌患者的HLA表型进行了特征分析。HLA - A32与临床反应相关(P = 0.025)。有反应者中HLA - A3和/或A32的频率高于无反应者(P = 0.008)。因此,这些结果表明,在体内,IL - 2可能增强针对肿瘤抗原的细胞介导免疫,并且某些MHC分子在内源性肿瘤抗原呈递方面比其他分子更有效。
