子宫内膜癌患者血清CP2、CA125、唾液酸和癌胚抗原检测的临床意义

目的探讨肿瘤标志物CP2、CA125、唾液酸（SA）和癌胚抗原（CEA）检测对子宫内膜癌患者的临床意义。方法选取154例具有肿瘤标志物检测结果的子宫内膜癌患者的临床病理资料进行回顾性分析。结果子宫内膜癌患者血清CP2、SA、CA125和CEA水平升高的百分率分别为23．4％、36．8％、19．0％和30．3％。血清CP2水平升高与手术病理分期、病理分化程度、附件受累、腹腔细胞学检查阳性及盆腔淋巴结转移相关（P值分别为0．002、0．040、0．019、0．019、0．005）;血清SA水平升高与附件受累、腹腔细胞学检查阳性相关（P值分别为0．021、0．000）;血清CA125水平升高与病理分化程度、宫颈受累和盆腔淋巴结转移相关（P值分别为0．014、0．006、0．018）;CEA与各临床病理特征间均无相关性（P均〉0．05）。血清CP2、CA125和CEA水平升高与患者预后相关（P值分别为0．016、0．000、0．016）,其中CA125水平与预后关系最为密切。结论子宫内膜癌缺乏特异性肿瘤标志物,CP2与子宫内膜癌临床病理特征相关性较强,CP2、CA125和CEA对患者预后有提示作用。

Clinical significance of serum CP2, CA125, salicylic acid and carcinoembryonic antigen in endometrial carcinoma

OBJECTIVE: To explore the clinical significance of CP2, CA125, salicylic acid (SA) and carcinoembryonic antigen (CEA) in endometrial carcinoma patients. METHODS: A retrospective study was carried out on 154 cases of endometrial carcinoma with tumor markers test results who were admitted to our department from Aug 1992 to Nov 2004. RESULTS: The patients were followed up for (38+/-28) months. 23.4%, 36.8%, 19.0% and 30.3% of cases were with abnormal values of CP2, SA, CA125 and CEA. CP2 abnormal level was related with the stage, cell differentiation, adnexa metastasis, positive peritoneal cytology and pelvic lymph node metastasis (P=0.002, P=0.040, P=0.019, P=0.019, P=0.005). SA abnormal level was related with the adnexa metastasis and positive peritoneal cytology (P=0.021, P=0.000). CA125 abnormal level was related with the cell differentiation, cervical metastasis and pelvic lymph node metastasis (P=0.014, P=0.006, P=0.018). The survival was related with CP2, CA125 and CEA (P=0.016, P=0.000, P=0.016), especially CA125. CONCLUSIONS: Among the commonly used tumor markers, CP2 is related with many clinical pathological parameters. CA125 elevation may strongly suggest worse prognosis.
