To investigate the expression and prognostic significance of RSF-1 in gastric adenocarcinoma.
RSF-1 expression was analyzed using immunohistochemical staining on tissue samples from a consecutive series of 287 gastric adenocarcinoma patients who underwent tumor resections between 2003 and 2006.The relationship between RSF-1 expression, clinicopathological factors, and patient survival was investigated.
Immunohistochemical staining indicated that RSF-1 is highly expressed in 52.6% of gastric adenocarcinomas. RSF-1 expression levels were closely associated with tumor size, histological differentiation, tumor stage, and lymph node involvement. Kaplan-Meier survival analysis showed that high RSF-1 expression exhibited a significant correlation with poor prognosis for gastric adenocarcinoma patients. Multivariate analysis revealed that RSF-1 expression is an independent prognostic parameter for the overall survival rate of gastric adenocarcinoma patients.
Our data suggest that RSF-1 plays an important role in gastric adenocarcinoma progression and that high RSF-1 expression predicts an unfavorable prognosis in gastric adenocarcinoma patients.
探讨RSF-1在胃腺癌中的表达及其预后意义。
采用免疫组织化学染色法分析2003年至2006年间连续287例行肿瘤切除术的胃腺癌患者组织样本中RSF-1的表达情况。研究RSF-1表达与临床病理因素及患者生存之间的关系。
免疫组织化学染色显示,52.6%的胃腺癌中RSF-1高表达。RSF-1表达水平与肿瘤大小、组织学分化、肿瘤分期及淋巴结受累密切相关。Kaplan-Meier生存分析表明,RSF-1高表达与胃腺癌患者预后不良显著相关。多因素分析显示,RSF-1表达是胃腺癌患者总生存率的独立预后参数。
我们的数据表明,RSF-1在胃腺癌进展中起重要作用,RSF-1高表达预示胃腺癌患者预后不良。
