- W2371855961 abstract "Objective To investigate the clinical value of sentinel lymph nodes(SLN) biopsy in treating gastric cancer.Methods The identification biopsy of intraoperative SLN on 40 patients with gastric cancer was performed.During the operation,the sentinel nodes were oriented by injecting methylene blue.The sentinel lymph nodes were then removed for the pathological studies with HE staining and immunohistochemical method.The results were analyzed by using the statistical method to investigate the expression of intraoperative sentinel lymph node after the injection of methylene blue.Results There were 39 patients whose SLN were detected among of 40 patients and the detection rate was 97.5%.Totally,54 lymph nodes were detected,with an average of 1.35 per patient.The SLN histological prediction showed that the accuracy rate of the lymph node metastasis in the stomach cancer region was 92.6%(36/39),the sensitivity was 87.5%(21/24) and false negative rate was 12.5%(3/24).Moreover,the accuracy rate and sensitivity of the metastasis of lymph nodes around stomach through the SLN prediction decreased with the increase of the depth of gastric cancer invasion.The sensitivity and accuracy rate at T1 phase were 100%,T3 were 84.6% and 88.2% respectively.Among 21 cases of SLN metastasis,3 cases showed that SLN was the only metastatic site,and it appeared in T1 and T2 stage.Conclusion Sentinel node biopsy could provide an accurate information for the node metastasis in early gastric carcinoma and theoretical evidences both for the further prospective research and drawing up a reasonable operation scheme for early gastric cancer." @default.
