Objective:To investigate the metastasis of lymph nodes in gastric antrum cancer, in order to investigate the need for the dissection of 14v lymph nodes in radical gastrectomy for gastric antrum cancer. Methods: A total of 183 cases of gastric antrum cancer from January 2008 to December 2010 have been reviewed. Metastasis of 14v lymph nodes was analyzed. Results: Among the 183 patients, 12 patients had 14v lymph nodes metastasis (6. 6%). The metastasis of 14v lymph nodes was not significantly related with age, gender and Borrmann type, but related with the invasion depth, the size and the differentiation degree of tumor. All the 12 patients with 14v lymph nodes metastasis had No. 6 lymph node metastasis. 14. 5% of the patients with No. 6 lymph node metastasis had 1 4v lymph nodes metastasis. Conclusions: The metastasis rate of 14v lymph nodes in gastric antrum cancer was 6. 6%. The patients with a low degree of tumor differentiation are more likely to have 14v lymph nodes metastasis. The tumors of the patients who have 14v lymph nodes metastasis often have invaded gastric serosa. There is a close relationship between the metastasis of 14v lymph nodes and that of No. 6 lymph node. No. 6 lymph node can be a clinically effective and useful indicator for the dissection of 14v lymph nodes.%目的:分析胃窦癌胃周淋巴结转移的情况,探讨胃窦癌根治术是否有必要清扫14v组淋巴结.方法:回顾研究2008年1月-2010年12月胃窦癌患者183例的临床资料,分析14v组淋巴结转移情况,研究其转移规律,探讨14v组淋巴结清扫在标准的胃窦癌根治术(D2)中的价值.结果:183例患者中,12例患者14v组淋巴结发生转移,14v组淋巴结转移率为6.6%.14v组淋巴结转移与患者的年龄、性别及肿瘤的Borrmann分型无显著相关性,而与肿瘤的侵犯深度、肿瘤的直径、肿瘤的分化程度显著相关.14v组淋巴结发生转移的12例患者,其6组淋巴结均有转移;而第6组淋巴结发生转移的病例中,有14.5%的病例14v组淋巴结有转移.结论:胃窦癌14v组淋巴结转移率为6.6%,肿瘤分化程度低的患者更易发生14v组淋巴结转移,发生14v组淋巴结转移的患者其肿瘤往往已侵犯胃壁浆膜.14v组淋巴结转移与第6组淋巴结转移关系密切,第6组淋巴结可以作为是否行14v组淋巴结清扫的标志.
