Objective To evaluate T lymphocyte changes in esophagogastric junction adenocarcinoma (AEGJ) patients receiving early hyperthermic intraperitoneal perfusion chemotherapy (HIPEC) after radical resection.Methods 98 AEGJ cases were randomized into postoperative early paclitaxel HIPEC group (50 cases) and surgery only group (48 cases).The changes in TLC,CD3 +,CD4 +,CD8 + and CD4 + CD25 + were examined by using flow cytometry on the preoperaive d1,and on the postoperative d 9.Results There were significant differences in cellular ratios of TLC,CD3 +,CD4 +,CD8 + and CD4 + CD25 + between the two groups on postoperative d 9 [(1.85 ± 0.36) × 109/L,(1.28 ± 0.28) ×109/L,t=8.727,P＜0.001;76％ ±6％,65％ ±6％,t =8.680,P＜0.001;57％ ±8％,41％ ± 7％,t =10.246,P ＜0.001:20％ ±7％,25％ ±6％,t =4.037,P ＜0.001;4.2％ ±1.8％;6.7％ ± 2.0％,t =6.548,P ＜ 0.001].Conclusion Postoperative early HIPEC using paclitaxel improves the celluar immune activity of T cell subsets in advanced AEGJ patients.

Objective To evaluate the changes of CEA,CA19-9,CA72-4 of patients with advanced adenocarcinoma of the esophagogastric junction (AEGJ) who received ultra-early precise hyperthermic intraperitoneal perfusion chemotherapy (HIPEC) with paclitaxel (PTX) after radical surgery.Methods From Jul 2014 to Dec 2015 postoperative advanced AEGJ patients were divided to receive ultraearly precise HIPEC (87 cases,HIPEC group) and conventional therapy group (85 cases) in early stage after radical surgery.Serum levels of CEA,CA19-9 and CA72-4 were examined on preoperative day 1 and postoperative day 9.Results On post-op day 9,the level of CEA,CA19-9 and CA72-4 was (2.8 ± 1.3)ng/ml,(22 ±8)IU/ml,(4.1 ± 1.9)IU/ml in HIPEC group,while that was (3.4 ± 1.2)ng/ml,(25 ±11) IU/ml,(4.8 ± 2.1) IU/ml in control group respectively (t =2.453,P =0.015;t =2.241,P =0.026;t =2.154,P =0.033).Conclusion Ultra-early PTX-based HIPEC with advanced AEGJ after radical surgery lowers serum tumor makers of CEA,CA19-9,CA72-4,reducing body's tumor burden.
