ｎｍ２３是候选肿瘤转移抑制基因中最令人注目的基因，近年来在人乳腺癌、肝癌、肾癌和非小细胞肺癌中已证实其蛋白表达水平与其转移呈明显负相关［１，２］。本文分析了６４例胃癌患者１９２份标本的ｎｍ２３－Ｈ１在胃癌组织和相关转移淋巴节中的表达及临床意义。１材料与方
nm23 is one of the most striking genes in candidate tumor metastasis suppressor genes. In recent years, nm23 protein has been shown to have a negative correlation with its metastasis in human breast cancer, liver cancer, renal cell carcinoma and non-small cell lung cancer [1,2]. This article analyzes the expression and clinical significance of nm23-H1 in 192 specimens from 64 gastric cancer patients in gastric cancer tissues and related metastatic lymph nodes. 1 material and side
