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。

Diagnosis of bile duct hepatocellular carcinoma thrombus without obvious intrahepatic mass

AIM:To study the diagnosis of hepatocellular carcinoma(HCC)presenting as bile duct tumor thrombus with no detectable intrahepatic mass.METHODS:Six patients with pathologically proven bile duct HCC thrombi but no intrahepatic mass demonstrated on the preoperative imaging or palpated intrahepatic mass during operative exploration,were collected.Their clinical and imaging data were retrospectively analyzed.The major findings or signs on comprehensive imaging were correlated with the surgical and pathologic findings.RESULTS:Jaundice was the major clinical symptom of the patients.The elevated serum total bilirubin,direct bilirubin and alanine aminotransferase levels were in concordance with obstructive jaundice and the underlying liver disease.Of the 6 patients showing evidence of viral hepatitis,5 were positive for serum alpha fetoprotein and carbohydrate antigen 19-9,and 1 was positive for serum carcinoembryonic antigen.No patient was correctly diagnosed by ultrasound.The main features of patients on comprehensive imaging were filling defects with cup-shaped ends of the bile duct,with large filling defects presenting as casting moulds in the expanded bile duct,hypervascular intraluminal nodules,debris or blood clots in the bile duct.No obvious circular thickening of the bile duct walls was observed.CONCLUSION:Even with no detectable intrahepatic tumor,bile duct HCC thrombus should be considered in patients predisposed to HCC,and some imaging signs are indicative of its diagnosis.     

A case of common bile duct stone with cholangitis presenting an extraordinarily high serum CA19-9 value.

A 63-year-old male complained of right upper abdominal pain and jaundice. Laboratory data on admission showed hyperbilirubinemia, elevation of biliary enzymes and an extraordinarily high value of serum CA19-9 (60,000 U/ml). Diagnostic imaging modalities including abdominal ultrasonogram, abdominal CT and PTC suggested a stone impaction of the common bile duct. Jaundice subsided after PTC-drainage in association with decreasing serum CA19-9 value, which returned to the normal level six weeks later. Spontaneous delivery of the stone via the fistula was confirmed by cholangiography through the drainage tube. Though there are few reports of such a high serum CA19-9 level, the possibility of benign biliary tract disease should be considered in patients showing an extraordinarily high serum CA19-9 value.     

High serum concentrations of sialyl Tn antigen in carcinomas of the biliary tract and pancreas

Sialyl-Tn (STn) antigen is a cancer-associated carbohydrate antigen expressed in cancers of the digestive tract. In the present study, we compared the serum level of STn antigen in 14 patients with benign diseases of the biliary tract and pancreas, 15 patients with bile duct cancers, and 9 patients with cancer of the pancreas. High levels of serum STn (>45 U/ml) were frequently detected in patients with carcinoma of the biliary tract (53.3%) or pancreas (55.6%), compared with the detection of high levels in those with benign diseases (14.3%;P < 0.05). Serum levels of STn did not correlate with the presence of jaundice, cholangitis, or pancreatitis, or with the level of carcinoembryonic antigen (CEA) or carbohydrate antigen (CA) 19–9. In cancer tissues, the expression of STn antigen detected by immunostaining correlated significantly with serum STn (P < 0.05). Our results indicate that measurement of serum STn level may be potentially useful for the diagnosis of carcinomas of the biliary tract and pancreas, particularly when combined with other tumor markers such as CEA or CA19-9.     

Value of serum bilirubin levels in selecting patients for magnetic resonance cholangiopancreatography

BACKGROUND/AIMS: To determine the value of serum bilirubin levels in selecting patients for MRCP. METHODOLOGY: The medical records of 142 patients who underwent MRCP between January 2002 and December 2004 were retrospectively reviewed. Clinical features, serum bilirubin levels, and MRCP results were recorded. The patients were categorized into 4 groups, according to serum bilirubin levels and MRCP findings. Bilirubin levels were considered elevated above 23.9 micromol/L for total bilirubin and above 6.8 micromol/L for direct bilirubin. Sensitivity, specificity, accuracy, and predictive values of serum bilirubin levels in identifying pancreatobiliary duct diseases were assessed. RESULTS: Complete medical records were found for 135 patients. Abnormal MRCP results were found in 75 patients (56%). Choledocholithiasis and both malignant and benign bile duct strictures represented 40%, 28%, and 23% of abnormal MRCP findings, respectively, with mean values of total and direct serum bilirubin levels of 77.9 +/- 51.6 microM and 34.7 +/- 30.3 microM (for choledocholithiasis), 170 +/- 115 microM and 56 +/- 40 microM (for malignant bile duct stricture), and 44 +/- 32 microM and 20 +/- 16 microM (for benign bile duct stricture), respectively. Sensitivity, specificity, and accuracy of serum bilirubin level tests, for the diagnoses of pancreatobiliary duct diseases, were 77%, 80%, and 79%, respectively; the positive and negative predictive values were 83% and 74%, respectively, and the corresponding likelihood ratios were 3.8 and 0.3. CONCLUSIONS: Serum bilirubin level tests alone are not sufficiently accurate for the diagnoses of pancreatobiliary duct diseases, and hence, such tests are of low importance in selecting patients for MRCP.
