胃癌是我国发病率和死亡率最高的恶性肿瘤之一,每年新增病例约30余万,其中死亡人数达17万左右。在目前住院病例中,90%以上为进展期胃癌,即使施行根治手术,5年生存率仍徘徊在30%左右。根治术后腹膜种植性转移占40%～50%,是影响预后的首要因素。因此,掌握胃癌腹膜转移规律,确立亚临床转移的早期诊断指标或预测指标及防治靶点,建立有效的预防和综合治疗体系,是提高远期疗效的关键,也是目前国内外胃癌治疗研
Gastric cancer is one of the most malignant tumors with the highest morbidity and mortality in China. About 30 million new cases are added each year, of which about 170,000 people have died. In the current inpatient cases, more than 90% of advanced gastric cancer, even if the implementation of radical surgery, 5-year survival rate still hovering around 30%. Peritoneal metastasis after radical surgery accounted for 40% to 50%, is the primary factor affecting the prognosis. Therefore, to grasp the law of peritoneal metastasis of gastric cancer, to establish early diagnosis of subclinical metastases or predictors and targets and prevention and treatment targets, to establish an effective prevention and comprehensive treatment system is to improve the long-term efficacy of the key, but also the current domestic and international treatment of gastric cancer research
