探讨胆汁肿瘤标志物对胆管良恶性疾病的诊断价值

目的探讨胆汁肿瘤标志物对胆管良恶性疾病的诊断价值。方法160例因胆道疾病需要ERCP治疗者,ERCP时取胆汁检测胆汁肿瘤标志物（CA19-9、CEA和CA242）和细菌培养。结果恶性狭窄组与良性疾病组间胆汁和血清CA19-9、CEA、CA242水平差异均有统计学意义（P〈0．05）;根据ROC曲线制定恶性狭窄的胆汁肿瘤标志物界限值：CA19-9239ku／L,CEA40ng／ml,CA24260ku／ml。CEA敏感度、准确度、阴性预测值与血液标志物比较差异有统计学意义（P〈O．05）。3种胆汁标志物的特异性与血清比较差异无统计学意义。胆管癌、胰腺癌、十二指肠乳头癌与胆管旁转移癌、肝癌比较CA19-9水平差异有统计学意义（P〈0．05）;无论是恶性狭窄组还是良性疾病组,细菌阳性胆汁与阴性胆汁组间CA19-9水平比较差异均有统计学意义（P〈0．05）。结论胆汁CA19-9、CEA、CA242水平对鉴别胆道良恶性疾病有一定帮助,但并不明显优于血清标志物。胆汁细菌感染可引起胆汁CA19-9水平升高,但不影响良恶性诊断结果。

腹水端粒酶、DNA倍体、CEA、CA19-9和血清-腹水白蛋白梯度对良恶性腹水的鉴别诊断意义

背景:确定腹水的良恶性在临床上具有重要意义,但恶性腹水的早期诊断相对困难,临床常规检测手段的漏诊率较高,且阴性结果不能排除肿瘤。目的:探讨腹水端粒酶、DNA倍体、CEA、CA19-9和血清-腹水白蛋白梯度(SAAG)对鉴别诊断良恶性腹水的意义。方法:纳入77例腹水患者(恶性腹水组41例,良性腹水组36例),分别检测腹水端粒酶、DNA倍体、CEA、CA19-9、白蛋白和血清白蛋白含量。结果:恶性腹水组腹水端粒酶、DNA异倍体比例、CEA、CA19-9明显高于良性腹水组,SAAG明显低于良性腹水组,差异均有统计学意义(P0.01)。腹水端粒酶和CEA的鉴别诊断准确性较高,5项指标联合检测的敏感性显著高于各指标单独检测(P0.05)。结论:腹水端粒酶、DNA倍体、CEA、CA19-9和SAAG可用于鉴别诊断良恶性腹水,联合检测可提高诊断敏感性。     

The assessment of biliary CA 125, CA 19-9 and CEA in diagnosing cholangiocarcinoma--the influence of sampling time and hepatolithiasis

BACKGROUND/AIMS: This study was conducted to assess the clinical value of biliary CA 19-9, CA 125 and CEA sampled in different situations for the diagnosis of cholangiocarcinoma. METHODOLOGY: Bile was obtained from patients with bile duct obstruction on the day of biliary drainage and 3 days later separately. The etiology of biliary obstruction included choledocholithiasis (N = 51), hepatolithiasis (N = 19) and cholangiocarcinoma (N = 28). Patients of the former two conditions were all complicated with cholangitis. RESULTS: The sensitivity of biliary CEA, CA 19-9 and CA 125, whenever checked were all less than 70%. The biliary CEA and CA 19-9 were elevated in the presence of cholangitis. In addition, the biliary CEA was also increased in the patients with hepatolithiasis. The specificity of CA 125 was better than those of CEA and CA 19-9 (75.7% vs. 33.3% and 60%, respectively) on the day of biliary drainage. The diagnostic efficiency was slightly improved when combining biliary CA 125 and CEA. CONCLUSIONS: As the biliary CA 125 was less affected by inflammation and hepatolithiasis, it is more useful than CEA and CA 19-9 in the diagnosis of cholangiocarcinoma. The single tumor marker test of CA 125 or combined tumor marker test of CEA and CA 125 may be used as a useful complement to other investigative methods to differentiate benign from malignant causes of the bile duct obstruction.

Comparative studies of DU-PAN-2, carcinoembryonic antigen, and CA19-9 in the serum and bile of patients with pancreatic and biliary tract diseases: evaluation of the influence of obstructive jaundice

The levels of DU-PAN-2 antigen, carcinoembryonic antigen, and CA19-9 in serum and bile of patients with pancreatic and biliary tract diseases were measured. The sensitivities (true positive) of DU-PAN-2 in serum to pancreatic carcinoma (64%) and to biliary tract carcinoma (62%) were similar to those of CA19-9 in serum (69% and 72%, respectively). Nine of 18 (50%) patients with CA19-9-negative pancreatic carcinoma tested positive for DU-PAN-2. The sensitivities of CEA to pancreatic carcinoma (56%) and to biliary tract carcinoma (52%) were lowest. The measurement of these antigens in bile seemed to be of little diagnostic value in differentiating between malignant and benign diseases. False positives of these three assays occurred frequently in patients with benign pancreatic or biliary tract disease coupled with obstructive jaundice. After percutaneous transhepatic biliary drainage, serum DU-PAN-2 and CA19-9 levels returned to normal ranges in patients with benign diseases, but not in patients with carcinoma of the pancreas or of the biliary tract. Serum CA19-9 and DU-PAN-2 antigens are useful tumor markers for pancreatic and biliary tract carcinomas. Longitudinal assays of these antigens may be useful for the differential diagnosis of patients with obstructive jaundice.     

Laparoscopic peritoneal lavage cytology and immunocytology in pancreatic and periampullary carcinoma

BackgroundFree tumour cells in the peritoneal cavity of patients with pancreatic carcinoma carry a poor prognosis. Reactive or degenerative mesothelial cells can make cytological interpretation with conventional stains difficult. Detection of the tumour-associated antigens carcinoembryonic antigen (CEA) and CA19-9 may improve detection.MethodsAt staging laparoscopy, 22 patients with pancreatic or periampullary tumours had ascitic fluid aspirated or peritoneal lavage performed. Both conventional and immunocytologically stained preparations were examined. Antibodies to CEA and CA19-9 and the epithelial marker BerEP4 were used. Lavage fluid from ten patients having operative treatment for benign pancreatic or biliary conditions was also examined.ResultsNo malignant cells on conventional cytological criteria were recovered.Thirteen of the 22 patients with pancreatic or periampullary carcinoma had peritoneal cells that were positive for CEA and/or CA19-9. None was positive for BerEP4. No patients with resectable disease had cells that were positive for CEA or CA19-9 compared with 13 of 18 (72%) who had unresectable disease. One patient (10%) with benign disease (chronic pancreatitis) had cells recovered that were weakly positive for CEA but negative for CA19-9 and BerEP4.DiscussionRecovery of cells from the peritoneal cavity of patients with pancreatic or periampullary carcinoma that are expressing the tumour-associated antigens CEA or CA19-9 does not indicate the presence of free tumour cells but is associated with advanced disease.
