[摘要] 目的 探討血清D-二聚體、CA-199、CA-125、CA-724和CEA在慢性胰腺炎和胰腺癌鑒別診斷中的臨床應用價值。方法 方便選取無錫市第二人民醫(yī)院2012年1月—2015年12月收治的胰腺癌患者30例、慢性胰腺炎患者30例,分別作為胰腺癌組和慢性胰腺炎組并檢測D-二聚體、CA-199、CA-125、CA-724及CEA 5個觀察指標。兩組分別使用免疫比濁法進行血漿D-二聚體檢測以及使用化學發(fā)光法進行4個腫瘤標志物檢測。 結果 胰腺癌組D-二聚體值(1.67±0.26)、CA-199值(462.1±126.5)、CA-125值(330.7±133.2)、CA724值(16.4±10.52)和CEA值(31.84±12.39);慢性胰腺炎組D-二聚體值(0.22±0.04)、CA-199值(83.69±33.36)、CA-125值(15.97±2.78)、CA724值(9.54±7.68)和CEA值(4.44±0.76)。其中D-二聚體、CA-199、CA-125及CEA檢測值在胰腺癌組顯著高于在慢性胰腺炎組,兩組比較差異有統(tǒng)計學意義(P<0.05)。另外,D-二聚體在兩組比較中敏感性和特異性分別為60.0%和96.7%;CA-199敏感性及特異性分別是66.7%和70.0%;CA-125的敏感性和特異性分別是63.3%和86.7%;CEA的敏感性和特異性分別是33.3%和90.0%,其中D-二聚體、CA-199、CA-125個指標在兩組比較差異有統(tǒng)計學意義(P<0.05)。結論 D-二聚體、CA-199和CA-125在鑒別慢性胰腺炎和胰腺癌具有較好應用價值,總體來說綜合敏感性和特異性的檢測結果,D-二聚體指標在鑒別診斷應用方面優(yōu)于CA-199和CA-125。

[Abstract] Objective To explore clinical value of D-dimer,CA-199,CA-125,CA-724 and CEA for differential diagnosis of pancreatic cancer (PC) and chronic pancreatitis(CP). Methods Convenient selection 30 patients with pancreatic cancer and 30 patients with chronic pancreatitis from January 2012 to December 2015 were enrolled to PC group and CP group respectively and the sserum level of D-dimer,CA-199,CA-125,CA-724 and CEA were tested in this retrospective analysis. The serum level of D-dimer was detected by immunoturbidimetry and the serum level of four tumor markers was detected by chemiluminescence. Results Level of D-dimer,CA-199,CA-125,CA-724 and CEA in CP group are (0.22±0.04), (83.69±33.36),(15.97±2.78),(9.54±7.68) and (4.44±0.76), respectively while in PC group are (1.67±0.26), (462.1±126.5), (330.7±133.2), 16.4±10.52) and (31.84±12.39), respectively. The level of D-dimer,CA-199,CA-125 and CEA are significantly higher in PC group than those in CP group(P<0.05).Sensitivity and specificity of D-Dimer are 60.0% and 96.7% in PC versus CP group, while sensitivity and specificity of CA-199 are 66.7% and 70.0%; CA-125 63.3% and 86.7%; 33.3% and 90.0% for CEA. The sensitivity and specificity difference are significant in D-dimer, CA-199 and CA-125 between the two groups (P<0.05). Conclusion In differential diagnosis for pancreatic cancer and chronic pancreatitis,serum level of D-dimer and CA-199, CA-125 have shown promising value. Generally speaking, combined with both sensitivity and specificity test D-dimer is more applicable than the tumor markers.

在世界范圍胰腺癌是死亡率排第四位的惡性腫瘤[1]。胰腺癌的獨立風險因子主要包括肥胖、吸煙、慢性胰腺炎、遺傳性胰腺炎、高脂飲食和糖尿病[2-4]。慢性胰腺炎是胰腺慢性不可逆的進展性炎癥性疾病。慢性胰腺炎多因胰腺組織纖維化而最終導致胰腺外分泌和內(nèi)分泌功能的不足的表現(xiàn)。酗酒是慢性胰腺炎的主要病因,其他病因還包括膽道疾病、高脂血癥、高鈣血癥、自身免疫性疾病、胰腺先天性異常及胰腺外傷或手術、急性胰腺炎導致胰管狹窄等。……
