RESUMEN
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.
RESUMEN
Patients with advanced gastric cancer have a poor prognosis, which remains the clinical concerned hot topic. The main previous treatments for advanced gastric cancer were adjuvant chemotherapy and palliative surgery, however, the application of conversion therapy has improved the survival in recent years. There are still many problems and challenges for conversion therapy because of its initial stage, such as the definition of advanced gastric cancer and conversion therapy, the selection of suitable population for conversion therapy, and the role of surgery in conversion therapy. Precision medicine will be applied to conversion therapy for advanced gastric cancer in the future, which would benefit more patients.
