RESUMO
Comprehensive treatment of gastric cancer is mainly based on the pathological staging. The T stage mainly depends on the accurate determination of the depth of the tumor invasion. The accurate T stage should be standardized pathological examination and continuous sectioning. N stage may be influenced by the number of lymph node examined. Insufficient lymph node examined may lead to stage migration. Therefore, standardizing lymph node dissection and lymph node harvest after surgery is important. M stage is mainly to improve the detection rate of peritoneal lavage cytology (CY), identify high risk factors for peritoneal metastasis, and optimize the prediction of peritoneal metastasis molecular markers, as a complementary methods of clinical examination. Currently, the quality of standardized pathological diagnosis of gastric cancer in China still needs to be improved. This article mainly elucidates the related studies and clinical experience of our center on how to do better in the optimization of gastric cancer TNM staging and pathological quality control.
