Clinical Analysis Of The Relationship Between The Method Of Gastrectomy And The Location And Lymph Node Metastasis Of Gastric Carcinoma

Purpose:Gastric cancer surgery clinical data on disease treatment center of Jilin University in General Surgery were retrospectively analyzed to explore the the clinicopathological biological differences between the proximal gastric cancer, central cancer and stomach, the lower part of cancer as well as the law of the corresponding regional lymph node metastasis, revealing its clinical significance, in order to take reasonable, effective and standardized surgical treatmentMethods:Collection of Jilin University general surgery disease treatment center, radical resection of gastric cancer standard line from September2009March2012(D2), and extended radical mastectomy (D2or more) disease (200cases). All eligible cases preoperative gastroscopy diagnosed as gastric cancer, radical extent of Class A or Class B The proximal gastric cancer was50cases,43cases of stomach central cancer, cancer of stomach and lower part of the107cases,138cases of men and62women. The number of cases of lymph node dissection≥15postoperative gross specimen and lymph nodes were sent to hospital Pathology for pathological examination Differences in contrast to the proximal gastric cancer, central cancer and inferior part of cancer clinical pathology results among the three groups, the difference between lymph node metastasis in clinical analysis and different surgical procedures of choice in different parts of the gastric cancer.Result:By the pathologic findings and lymph node metastasis of gastric cancer of different parts of the analysis. Gender composition of the upper stomach cancer patients, tumor diameter, macroscopic type, degree of differentiation and growth pattern, depth of invasion, pathologic stage, serosa, and residual stump with the central stomach cancer and stomach and lower part of the cancer significantly different compared to (P <0.05), and their respective lymph node metastasis.In the patient’s age, the total number of lymph node metastasis and lymph node metastasis station, between the three groups was not statistically significant (P <0.05). Gastric cancer three different groups of tumor location, surgical therapy selection effects was not statistically significant (p>0.05). Through comparative study of three different parts of gastric cancer lymph node metastasis and dissection is one of the most important factor affecting their prognosisConclusion:Gastric cancer occurred in different parts of the Biology and lymph node metastasis location was different. Proximal gastric cancer showed the evil characteristics of the biological behavior of lymph node metastasis is not more obvious than the other parts. Lymph node metastasis and tumor depth of invasion, gross type, growth pattern, and serosal involvement have significant correlation (P <0.05), with the lesion, degree of differentiation, the tumor body size is not obvious.No matter what radical gastric resection does not affect the survival rate of patients, however, the number and dissection of lymph node metastasis is the main factor affecting the prognosis of gastric cancer. In this study, all cases were lymph node metastasis, which No.36lymph node metastasis rate the the No.7group and No.8a group2station lymph node metastasis, the highest incidence of group, surgery must be swept.
