The Combined Elevation of Tumor Markers CA 19-9 and CA 125 in Liver Disease Patients Is Highly Specific for Severe Liver Fibrosis

Increased tumor markers in patients with liver cirrhosis are often considered to be unspecific. The use of this unspecific elevation to discriminate minimal fibrosis from severe fibrosis has never been explored. We aimed to answer the question, Do tumor markers predict severe liver fibrosis? The study group consisted of 125 patients with alcoholic liver disease, hepatitis B, or hepatitis C with available liver biopsy. Tumor markers CA 19-9, CA 15-3, and CA 125 were determined using routine laboratory methods and correlated with the extent of liver fibrosis. Fibrosis stages 1 and 2 were classified as minimal fibrosis; stages 3 and 4, as severe fibrosis. Tumor markers CA 19-9, CA 125, and CA 15-3 increased with stage of fibrosis. For separating patients with mild fibrosis (F1+F2) from patients with severe fibrosis (F3+F4), CA 19-9 had a sensitivity of 70.5% and a specificity of 88.6, CA 125 had 38.1% and 89.7%, and CA 15-3 had 19.0% and 93.0%, respectively. Logistic regression of a combined score of CA19-9 and CA 125 values revealed that an increase of 1 point of the CA 19-9/CA125 score resulted in a 1.6 times increase in likelihood of the presence of severe fibrosis. The CA 19-9/CA 125 score achieved a similar specificity (97.1% vs. 100%) but a higher sensitivity (42.9% vs. 33.3%) than the widely used cirrhosis discriminant score of Bonacini. A specificity (98.5%) similar to that of the CA 19-9/CA 125 score was reached by the easier determination of the combined elevation of CA 19-9 and CA 125, which had the best positive predictive value, 92.9%. The excellent predictive ability of the combined elevation of CA 19-9 and CA 125 for severe liver fibrosis (F3+F4) was confirmed in an independent group of patients with liver disease. The combined elevation of CA 19-9 and CA 125 is useful for identifying patients with advanced fibrosis or cirrhosis with high specificity. Patients without a combined elevation of CA 19-9 and CA 125 still require histological examination to identify severe fibrosis or cirrhosis.     

Type 2 diabetes mellitus and CA 19-9 levels

AIM： To prospectively investigate serum CA 19-9 levels in type 2 diabetic patients in comparison with age and gender-matched control subjects.
METHODS： We recorded duration of diabetes and examined fasting glucose levels, HbAlc levels and serum CA 19-9 levels in 76 type 2 diabetic patients and 76 controls. Abdominal CT was performed in order to eliminate abdominal malignancy in the diabetic and control groups.
RESULTS： The average CA 19-9 level was 46.0 ± 22.4 U/mL for diabetic patients whereas it was 9.97± 7.1 U/mL for the control group （P 〈 0.001 ）. Regression analysis showed a positive correlation between diabetes and CA 19-9 independent from age, gender, glucose level and HbAlc level （t = 8.8, P 〈 001 ）. Two of the diabetic patients were excluded from the study because of abdominal malignancy shown by CT at the initial evaluation. For all patients, abdominal CT showed no pancreatic abnormalities.
CONCLUSION： CA 19-9 is a tumor-associated antigen, which is elevated in pancreatic, upper gastrointestinal tract, ovarian hepatocellular, and colorectal cancers, as well as in inflammatory conditions of the hepatobiliary system, biliary obstruction and in thyroid diseases. Diabetes has been claimed to be a risk factor for pancreatic cancer, which is increasing its incidence and has one of the lowest survival rates of all cancers. CA 19-9 is used in the diagnosis of pancreatic cancer but is also a marker of pancreatic tissue damage that might be caused by diabetes. We propose that a higher cutoff value of CA 19-9 should be used in diabetics to differentiate benign and malignant pancreatic disease, and subtle elevations of CA 19-9 in diabetics should be considered as the indication of exocrine pancreatic dysfunction.     

Type 2 diabetes mellitus and CA 19-9 levels

AIM: To prospectively investigate serum CA 19-9 levels in type 2 diabetic patients in comparison with age- and gender-matched control subjects. METHODS: We recorded duration of diabetes and examined fasting glucose levels, HbA1c levels and serum CA 19-9 levels in 76 type 2 diabetic patients and 76 controls. Abdominal CT was performed in order to eliminate abdominal malignancy in the diabetic and control groups. RESULTS: The average CA 19-9 level was 46.0 ± 22.4 U/mL for diabetic patients whereas it was 9.97 ± 7.1 U/mL for the control group (P ＜ 0.001 ). Regression analysis showed a positive correlation between diabetes and CA 19-9 independent from age, gender, glucose level and HbA1c level (t = 8.8, P ＜ 001 ). Two of the diabetic patients were excluded from the study because of abdominal malignancy shown by CT at the initial evaluation. For all patients, abdominal CT showed no pancreatic abnormalities.

糖类抗原125与N末端B型利钠肽原相结合在慢性心力衰竭中的应用

目的探讨糖类抗原125(CA125)与N末端B型利钠肽原(NT-pro BNP)相结合对慢性心力衰竭患者病情评估和治疗的指导作用。方法选择284例心脏病患者,测定血清CA125和NT-pro BNP水平。根据纽约心脏学会(NYHA)心功能分级标准比较心功能Ⅰ级、Ⅱ级、Ⅲ级、Ⅳ级患者间两者水平有无差异;再根据患者肾功能是否正常,分别比较肾功能正常组和肾功能异常组不同心功能程度患者间两者水平的差异。结果 284例心脏病患者,CA125和NT-pro BNP水平有显著相关性(r=0.49,P0.01);NT-pro BNP水平在心功能Ⅰ级、Ⅱ级、Ⅲ级患者中随心功能分级程度增高而升高,差异有统计学意义(P0.05),但心功能Ⅳ级患者NT-pro BNP水平低于心功能Ⅲ级患者,差异无统计学意义;CA125水平随心功能分级程度增高而升高,差异有统计学意义(P0.05)。145例肾功能正常[e GFR≥60 m L/(min·1.73 m2)]患者CA125和NT-pro BNP水平均随心功能分级程度增高而升高,差异有统计学意义(P0.05),二者之间有显著相关性(r=0.700,P0.01);139例肾功能异常[e GFR60 m L/(min·1.73m2)]患者CA125和NT-pro BNP水平有显著相关性(r=0.292,P0.01),NT-pro BNP水平在心功能Ⅰ级、Ⅱ级、Ⅲ级随心功能分级增高而升高,差异有统计学意义(P0.05),但心功能Ⅱ级与心功能Ⅳ级之间差异无统计学意义,且心功能Ⅳ级患者NT-pro BNP水平显著低于心功能Ⅲ级患者(P0.05),而CA125水平随心功能分级程度增高而升高,差异有统计学意义(P0.05)。结论血清CA125和NT-pro BNP水平在慢性心力衰竭患者中均升高,二者均可作为评估慢性心力衰竭患者心功能的有价值指标;但肾功能异常会影响NT-pro BNP水平,对CA125水平则无明显影响。因此,CA125与NT-pro BNP相结合对指导慢性心力衰竭患者诊疗,尤其当肾功能不全时,具有重要价值。
