早期胃癌浆膜分型与淋巴结转移的关系

Relationship between serosa type and lymph node metastasis

目的:探讨早期胃癌浆膜分型与淋巴结转移的关系,为淋巴结的合理清除提供依据。方法:回顾性分析164例早期胃癌的浆膜分型与淋巴结转移情况。结果:浆膜正常型胃癌患者的淋巴结转移率为9.4%,反应型为20.2%,两者淋巴结转移率比较差异有统计学意义,χ2=3.85,P<0.05。浆膜正常型患者中,黏膜癌淋巴结转移率为2.0%,且局限于第1站(N1);黏膜下癌淋巴结转移率为20.0%,且局限于(N1+No.7)。浆膜反应型患者中,m癌、sm癌第2站(N2)转移率分别为3.0%和26.1%。结论:浆膜分型评估早期胃癌淋巴结的转移规律是较实用和可靠的方法。

OBJECTIVE： To approach the relationship between the type of serosa invasion and lymph node metastasis in early gastric cancer in order to lay a foundation for rational lymph node dissection. METHODS： The type of serosa invasion and lymph node metastasis of 164 case of early gastric cancers were retrospectively analyzed. RESULTS： The incidence of lymph node metastasis of normal serosa and reactive serosa type was 9.4 and 20. 2% respectively, and there was a significant difference between the two groups（x^2 =3. 85,P〈0. 05）. Two percent of the cases of the mucosal carcinomas with normal serosa type got lymph node metastasis, and all the metastases were limited in N1 ; 20. 0% of the cases of submucosal carcinomas with normal serosa type got lymph node metastasis, and the metastases were limited in （N1 ＋No. 7）. N2 metastasis of mucosal carcinoma with reactive serosa type occurred in 3. 0 %, and submucosal carcinoma with reac tive serosa type in 26.1%. CONCLUSION： The method of using of type of serosa invasion to assess the lymph node metastasis is a practical and reliable.
