The relationship between lymph node metastasis and the scope of lymphadenectomy in gastric cancer

Objective:To investigate the characteristics of lymph nodes metastasis in gastric cancer and its guidance significance for the scope of lymphadenectomy.Methods: The clinicopathological data were collected in 103 patients with gastric cancer who underwented radical gastrectomy.Then the information of lymph node metastasis were collected and the lymph node metastasis rate were calculated.The relationship between lymph node metastasis rates and tumor diameters,clinical classification and Borrmann type were analyzed.Results: Among 103 patients with gastric cancer,lymph node metastases were 68.9%(71/103).With the increase of tumor diameter,lymph node metastasis rate and degree was also increased(P0.05).In clinical classification,the rate and degree of lymph node metastasis was elevated with clinical classification advancement of gastric cancer and they were significicantly lower in stageⅠthan in other stage(P0.01).In Borrmann type,lymph nodes metastasis in gastric cancer among patients in Borrmann type Ⅲ 81.6%(40/49) was higher than other Borrmann types(P0.05),while the degree of lymph node metastasis was highest in Borrmann type Ⅳ 32.4%(161/497).Conclusion: The rate and degree of lymph node metastasis was elevated with clinical advancement of gastric cancer.A reasonable lymph node dissection might be timely removal of tumor metastases.Then it could help the patients with gastric cancer reduce possibility of distant metastasis.
