为了解胃癌患者淋巴结转移的数量及其与传统解剖分类之间的关系,作者对305例行全胃切除术和扩大淋巴结切除术(R3/4)的胃癌患者进行总结。有淋巴结转移者191人,占62.9％。其转移与癌肿浸润深度有关。当癌肿仅浸润至粘膜、粘膜下层(T1)时,只有17％的患者有淋巴结转移,且89％的阳性淋巴结位于N1区。当癌肿浸润至肌层,淋巴结转移者增至53％,约80％的患者有透壁性浸润。有浆膜浸润者,约30％有主动脉旁淋巴结转移。 To understand the relationship between lymph node metastasis and traditional anatomical classification in gastric cancer patients, the authors summarized 305 patients with gastric cancer undergoing total gastrectomy and enlarged lymph node dissection (R3/4). There were 191 patients with lymph node metastasis, accounting for 62.9%. Its metastasis is related to the depth of cancer invasion. When the cancer infiltrated only to the mucosa and submucosa (T1), only 17% of patients had lymph node metastasis, and 89% of the positive lymph nodes were located in the N1 area. When the cancer infiltrated into the muscular layer, lymph node metastasis increased to 53%, and about 80% of patients had transmural infiltration. With serosa infiltration, about 30% had paraaortic lymph node metastases.
