早期胃癌(EGC)定为仅仅侵犯粘膜或粘膜下层的癌肿,不管是否有淋巴结转移(LNM),现在它被认为是一种可医好的恶性肿瘤。EGC的复发率很低,约1.4％～8.3％,其LNM率从7.8％～20.1％。EGC治疗后淋巴结转移对生存的影响仍有争论。很多研究报告有:LNM降低EGC生存,但两篇报告LNM与生存率无显著相关,这些较早的报道是基于少于500例的结果上,而另一些研究是根据综合生存数据,它去除了死于EGC不相关的疾病。 本研究阐明有LNM的EGC特征,检查EGC患者治疗后,LNM对生存的影响。
Early-stage gastric cancer (EGC) is defined as a cancer that invades only the mucosa or submucosa. Regardless of lymph node metastasis (LNM), it is now considered to be a curable malignancy. The recurrence rate of EGC is very low, about 1.4% to 8.3%, and its LNM rate is from 7.8% to 20.1%. The impact of lymph node metastasis on survival after EGC treatment remains controversial. Many studies have reported that LNM reduces EGC survival, but two reports that LNM has no significant correlation with survival rate. These earlier reports are based on the results of less than 500 cases, while others are based on comprehensive survival data, which removes Died of EGC unrelated diseases. This study clarified the characteristics of LNM EGC and examined the effect of LNM on survival after treatment of EGC patients.
