Abstract

Non-metastatic gene 23 (nm23) is a metastasis suppressor gene that is expressed in all tissues and decreased nm23 expression may be linked to poor prognosis. By immunohistochemical staining of nm23 protein antibodies this study examined the prognostic value of nm23 protein expression in 54 renal cell carcinoma (RCC) patients and analysed its relationship with tumour, node, metastases (TNM) surgical stage, Fuhrman nuclear grade, lymph node involvement and survival. Of the 54 RCC cases studied, 11 (20.4%) showed positive lymph node involvement while 43 (79.6%) were lymph node negative. There was no difference in nm23 protein expression between cases with and without lymph node involvement. In addition, nm23 protein expression was not related to TNM stage, Fuhrman nuclear grade or survival. More extensive studies are required to understand the effect of nm23 protein expression on the biological behaviour of RCC.
