Expression of the MAGE genes encoding tumor-rejection antigens on HLA-A1 and -Cw1601 recognized by cytotoxic T lymphocytes was investigated in esophageal carcinomas at the mRNA level by the semiquantitative reverse transcription-polymerase chain reaction method. MAGE-1 and -2 genes, but not MAGE-3, -3/-6 and -4a/-4b genes, were expressed in substantial proportions of the primary esophageal carcinomas and their metastatic lymph nodes. The proportion of MAGE-positive samples in the primary esophageal carcinomas correlated with the T factor of the TNM classification (pT1: 2 of 12 tumors, pT2: 1 of 6, pT3: 12 of 29, and pT4: 7 of 18). These results have important implications for specific immunotherapy of esophageal carcinomas using MAGE-1 gene product.

The expression of human leukocyte antigen (HLA) class I alleles was analyzed in 65 renal cell carcinomas using one-dimensional isoelectric focusing. Normal organ tissue and peripheral blood lymphocytes were used as controls. The patients were serologically typed using the standard microcytotoxicity test. Forty-two patients were staged as pT1 or pT2, and 23 patients had advanced tumor stages (pT3/pT4). In all cases the HLA-A,B phenotypes were confirmed using one-dimensional isoelectric focusing. The expression of HLA expression was reduced in two tumors [1 x HLA-A1(pT2); 1 x HLA-A28 (pT2)]. In three carcinomas the expression of HLA-A1 was lost. One tumor showed a combined loss of HLA-A2 and HLA-B38. These selective losses occurred in tumor stage pT3 (n = 1) or pT4 (n = 3; P = 0.013, Fisher's exact test). This leads to the conclusion that the loss of HLA expression is predominantly present in advanced tumor stages.
