PG - 2028-35 LID - 10.1158/1078-0432.CCR-07-4554 [doi] AB - PURPOSE: To investigate the effect of intraepithelial tumor-infiltrating lymphocytes (ieTIL) and their ligands expressed by cervical tumor cells on the outcome of cervical cancer patients. EXPERIMENTAL DESIGN: The prognostic value of ieTILs was investigated in 115 cases of cervical cancer. T-cell subsets, CD57(+) cells, and regulatory T cells (Treg) were enumerated. The associations of these different ieTIL subtypes with human leukocyte antigen (HLA) class I and MHC class I chain-related molecule A (MICA) expression were determined in relation to clinical variables and patient survival. RESULTS: Survival analysis showed that a high number of intraepithelial Treg (FoxP3(+)), a low CD8(+)/regulatory T-cell ratio, and a weak HLA-A expression were all associated with worse survival (P=0.034, 0.025, and 0.033, respectively, log-rank test). Further stratification of patient groups based on HLA-A-MICA expression and HLA-A-MICA-CD8(+)/Treg ratio revealed an even poorer survival (P=0.005). In a multivariate Cox analysis, low CD8(+)/Treg ratio (P=0.047), weak HLA-A-MICA expression (P=0.003), and weak HLA-A-MICA expression combined with low CD8(+)/Treg ratio (P=0.002) were all found to be independent unfavorable prognostic predictors in cervical carcinoma (hazard ratios, 2.7, 4.0, and 4.9, respectively). CONCLUSION: Weak HLA-A-MICA expression combined with low CD8(+)/Treg ratio reveals a patient group with the poorest survival in cervical cancer. As a single variable, low CD8(+)/Treg ratio was a significant independent unfavorable prognostic factor.
