Cyclooxygenase (COX)\u20102 plays a vital role in prognosis of cancer patients in terms of contribution to neoangiogenesis and apoptosis inhibition; however, the impact of COX\u20102 in immunomodulation has not been reported. We have evaluated the expression of COX\u20102 and its impact on infiltration of immune\u2010competent cells into the tumor cell nest in endometrial carcinoma. Tissue specimens from 70 endometrial carcinoma patients who had undergone a curative resection were evaluated for COX\u20102 expression and host immune status (CD8<jats:sup>+<\/jats:sup> T cells). COX\u20102 expression was associated with FIGO stage and myometrial invasion, but there was no statistically significant impact. CD8<jats:sup>+<\/jats:sup> T cells within cancer cell nest (Nest CD8) were inversely correlated with the expression level of COX\u20102 (<jats:italic>p<\/jats:italic> = 0.0006). Nest CD8 became an independent predictor of patient survival (Hazard ratio = 10.300, <jats:italic>p<\/jats:italic> = 0.0304) in Cox's multivariate analysis. The expression level of COX\u20102 was found to be a significant predictor of disease relapse in univariate analysis (<jats:italic>p<\/jats:italic> = 0.0294) but not in multivariate analysis (<jats:italic>p<\/jats:italic> = 0.5949). In conclusion, increased nest CD8 produced a survival advantage in endometrial carcinoma patients. Moreover, tumor\u2010produced COX\u20102, which reduces the infiltration of CD8<jats:sup>+<\/jats:sup> T cells into cancer cell nests, may allow tumors to avoid immune surveillance. \u00a9 2004
