Ny-ESO-1 expression and immunogenicity associated with transitional cell carcinoma: correlation with tumor grade.

NY-ESO-1 mRNA expression in transitional cell carcinoma was investigated by reverse transcription-PCR and immunohistochemistry. NY-ESO-1 mRNA was detected in 20 of 62 (32%) tumor specimens. There was a correlation between NY-ESO-1 expression and tumor grade: 0 of 4 (0%) grade 1 (G1), 6 of 26 (23%) grade 2 (G2), and 14 of 32 (44%) grade 3 (G3) tumors were NY-ESO-1 mRNA positive. Immunohistochemical analysis using NY-ESO-1-specific monoclonal antibody ES121 showed that 2 of 14 NY-ESO-1 mRNA- expressing G3 tumors were positive for NY-ESO-1. No NY-ESO-1 staining was observed in the panel of 30 G1 or G2 tumor specimens, including 6 NY-ESO-1 mRNA-positive cases. Sera from an expanded panel of 124 patients with transitional cell carcinoma were tested for the presence of NY-ESO-1 antibody. Seropositivity was observed in 9 of 72 (12.5%) patients with G3 tumors, whereas none of 52 patients with G1 or G2 tumors produced antibody against NY-ESO-1. In the 9 positive patients with NY-ESO-1 antibody, 4 had muscular invasive tumors, and 5 had carcinoma in situ.[1]
