摘要: Background Although tumor-infiltrating T cells have been documented in ovarian carcinoma, a clear association with clinical outcome has not established. Methods We performed immunohistochemical analysis of 186 frozen specimens from advanced-stage carcinomas to assess the distribution and conducted analyses. Molecular analyses were some tumors by real-time polymerase chain reaction. Results CD3+ detected within tumor-cell islets (intratumoral cells) 102 (54.8 percent); they undetectable 72 (38.7 remaining 12 (6.5 percent) could be evaluated. There significant differences distributions progression-free survival overall according presence or absence intratumoral (P<0.001 for both comparisons). The five-year rate was 38.0 percent among patients whose contained 4.5 ...
