随着早期胃癌发现率的提高和术式的改进,胃癌的予后明显改善.但早期胃癌淋巴结转移率颇高,约10～20%,影响早期胃癌的予后.作者以早期胃癌中淋巴结转移最高的粘膜下层胃癌为对象,讨论早期胃癌淋巴结转移与肿瘤及宿主各因素的关系.作者收集19年间188例早期胃癌,其中粘膜下层胃癌(Sm)106例,占56.4%,28例发生淋巴结转移、占26.5%,淋巴结转移率为粘膜内胃癌(m)4%的6.5倍.在转移的28例中,各站淋巴转移分别为N_1 20.8%,N_2 3.8%,N_3 1.9%.
With the increase of the detection rate of early gastric cancer and the improvement of the surgical method, the gastric cancer is improved obviously. However, the lymph node metastasis rate of early gastric cancer is high, about 10 to 20%, which affects the early gastric cancer. The authors used lymph node metastasis in early gastric cancer. The highest submucosal gastric cancer was used as the object to discuss the relationship between lymph node metastasis and tumor and host factors in early gastric cancer. The authors collected 188 cases of early gastric cancer, including submucosal gastric cancer (Sm) in 106 cases, accounting for 56.4%, and 28 cases of lymph node metastasis. 26.5% of the patients had a lymph node metastasis rate of 6.5 times that of intramural gastric cancer (m) 4%. In the 28 metastasis cases, lymph metastases were N_1 20.8%, N_2 3.8%, and N_3 1.9%, respectively.
