进展期胃癌（AGC）患者行胃癌根治术，对是否联合切除脾脏存在争议，本组对sl例AGC患者的外周血及脾静脉血的NK细胞活性和T细胞亚群进行了检测分析，从免疫学的角度对外周血及脾脏的细胞免疫状态进行评价，为合理开展合并脾切除的胃癌根治术提供免疫学依据。回材料和方法1．1研 In patients with advanced gastric cancer (AGC) undergoing radical gastrectomy, there is controversy as to whether or not joint resection of the spleen should be performed. In this group, NK cell activity and T cell subpopulations in peripheral blood and spleen venous blood of patients with AG were measured and analyzed. From an academic point of view, the evaluation of the cellular immune status of peripheral blood and spleen provides an immunological basis for the rational development of radical gastrectomy for splenectomy.
