Abstract:
Objective:To investigate the clinicopathological characteristics and immunohistochemical features of tumor-infiltrating lymphocyte(TIL) in ovarian serous adenocarcinoma,and their clinical value.Methods:The immunohistochemistry was used to observe 68 ovarian serous adenocarcinomacases'immunohistochemical features,and their correlations with clinicopathological characteristics were analyzed.Results:There were 43 cases with a large amount of TIL infiltrating in the 68 cases of serous adenocarcinoma,account for 63.24％.There were significant differences on the with or without a large amount of TIL infiltrating among the different tumor grade,different clinical stage,and different CA125 level (P ＜ 0.05).The numbers of CD3 +,CD4 + and CD8 + TIL in the cancer nest were significantly less than those in the stroma,with significantly statistical difference (P ＜ 0.05),Meanwhile the ratio of CD4 +/CD8 + in the cancer nest was significantly less than that in the stroma(P＜0.05).The ratio of CD4 +/CD8 + in the cancer nest and stroma at stage Ⅲ and with poor differentiation was significantly lower than in those at stage Ⅰ-Ⅱ and with good differentiation(P＜0.05).Meanwhile the ratio of CD8 +/FoxP3 + Treg in the cancer nest was less than that in the stroma(P＜0.05).The ratio of CD8 +/FoxP3 + Treg in the cancer nest at stage Ⅲ and with poor differentiation tumor was significantly lower than in those at stage Ⅰ-Ⅱ and with good differentiation(P＜0.05).The expression of GzmB in the cancer nest at stage Ⅲ and with poor differentiation tumor was significantly lower than that in the cancer nest at stage Ⅰ-Ⅱ and with good differentiation tumor(P＜0.05).Conclusions:With or without a large amount of TIL is related to tumor grade,clinical stage,and CA125 level inovarian serous adenocarcinoma.The numbers of TIL in ovarian serous adenocarcinoma increase considerably,but mainly in the stroma,and which may be related to several factors such as tumor cell differentiation and clinical stage.
