BMC杂志在世界上属什么级别？P53, Somatostatin receptor 2a and Chromogranin A immunostaining as prognostic markers in high grade gastroenteropancreatic neuroendocrine neoplasms.Abstract:BACKGROUND:High grade gastroenteropancreatic (GEP) neuroendocrine neoplasms (NEN) with a Ki67 proliferation index > 20%, include well-differentiated tumours grade 3 (NET G3) and poorly differentiated (PD) neuroendocrine carcinomas (NEC). Abnormal p53-expression is a feature of PD tumours, while expression of chromogranin A (CgA) and somatostatin-receptor 2a (SSTR-2a) may be a feature of well-differentiated tumours. The aim of this study was to elucidate the expression and prognostic value of these three markers in 163 GEP-NEN patients with a Ki67-index > 20%. METHOD:Clinical data, histopathology and overall survival were analysed according to Kaplan-Meier's method and Cox regression. The expression of SSTR-2a, CgA and synaptophysin was analysed in tumour specimens by immunohistochemistry, and semi-quantitatively scored as negative ( 30%). P53 was defined as normal when scored as heterogeneously positive (1-30%), and abnormal when negative (0%) or strongly positive (> 30%). RESULTS:In multivariate analysis, better survival was observed among patients with heterogeneously positive p53 compared to strongly positive (p  20%. Patients with heterogeneously positive p53 had the best prognosis. SSTR-2a was a positive prognostic marker in pancreatic NEN. Negative CgA was associated with a significantly worse OS compared to heterogeneously positive CgA-expression in a multivariate sub-analysis. Lower Ki67 index correlated significantly with heterogeneously positive p53, positive SSTR-2a and CgA expression.展开更多BMC CANCERBMC CANCER最新影响因子：期刊ISSN：1471-2407研究方向：医学-肿瘤学CiteScore：出版年份：2001出版地区：ENGLAND出版周期：Bimonthly是否OA：YES期刊官方网址：...期刊投稿网址：期刊coverage：Science Citation Index Expanded （科学引文索引扩展）NCBI查询：PubMed Central (PMC)链接全文检索 (pubmed central)
