ABSTRACT
Objective To investigate the predictive value of preoperative serum tumor markers test for lymph node metastasis of intrahepatic cholangiocarcinoma (ICC).Methods The retrospecgtive cohort study was conducted.The clinicopathological data of 69 patients with ICC who were admitted to the Xinhua Hospital of Shanghai Jiaotong University between May 2006 and May 2016 were collected.Among 69 patients with pathological diagnosis,24 with lymph node metastasis were allocated into the lymph node metastasis group and 45 without lymph node metastasis were allocated into the non-lymph node metastasis group.Tumor markers of the 2 groups were preoperatively detected,including alpha-fetoprotein (AFP),carcinoembryonic antigen (CEA),prostate specific antigen (PSA),CA19-9,CA125,CA242,CA153,CA724,CA211,neuron-specific enolase (NSE) and squamous cell carcinoma antigen (SCC).Receiver operating characteristic (ROC) curve was built,and critical value,sensitivity and specificity were calculated based on ROC curve.Coincident rate between significant indicators and results of pathological examination was calculated.Observation indicators(1) overall positive rates of tumor markers;(2) comparison of tmmor markers levels in the 2 groups;(3) tumor markers predicted ROC curve of lymph node metastasis and coincident rate between ROC curve and results of postoperative pathological examination.Measurement data with normal distribution were represented as (x)±s and comparison between groups was analyzed using the t test.Measurement data with skewed distribution were described as M (Q25,Q75) and comparison between groups was analyzed using the Wilcoxon rank sum test.Comparison of count data was analyzed by the chi-square test and Fisher exact probability.The statistically significant indicators were analyzed by the ROC curve.Results (1) Overall positive rates of tumor markerspositive rates of AFP,CEA,PSA,CA19-9,CA125,CA242,CA153,CA724,CA211,NSE and SCC in 69 patients were 27.5% (19/69),29.0% (20/69),4.3% (3/69),69.6% (48/69),36.2% (25/69),50.7% (35/69),26.1% (18/69),21.7% (15/69),62.3% (43/69),31.9%(22/69) and 21.7%(15/69),respectively.Positive rates of AFP,CEA,CA19-9,CA125,CA242,CA153,CA724,CA211,NSE and SCC were more than 20%,which became comparison indicators of 2 groups.(2) Comparison of tumor markers levels in the 2 groupslevels of CA19-9,CA125,CA242 and CA211 were 284.9 U/mL (42.5 U/mL,730.3 U/mL),63.6 U/mL (23.4 U/mL,172.1 U/mL),71.7 U/mL (25.6 U/mL,138.9 U/mL),6.7 μg/L (3.9 μg/L,17.5 μg/L) in the lymph node metastasis group and 58.0 U/mL (25.9 U/mL,405.9 U/mL),18.2 U/mL (11.7 U/mL,33.8 U/mL),11.0 U/mL (3.7 U/mL,41.7 U/mL),3.7 μg/L (2.7 μg/L,6.9 μg/L) in the non-lymph node metastasis group,respectively,with statistically significant differences between the 2 groups (Z=2.016,3.213,3.143,2.482,P<0.05).(3) Tumor markers predicted ROC curve of lymph node metastasis and coincident rate between ROC curve and results of postoperative pathological examinationarea under the ROC curve of CA19-9,CA125,CA242 and CA211 were respectively 0.648 [95% confidence interval (C I)0.515-0.781,P<0.05],0.736 (95% CI0.608-0.864,P<0.05),0.731 (95% CI0.603-0.859,P<0.05),0.714 (95% CI0.581-0.847,P<0.05).The positive critical value,sensitivity and specificity of CA19-9,CA125,CA242 and CA21 were 150.6 U/mL,35.7 U/mL,43.4 U/mL,6.0 μg/L and 62.5%,66.7%,70.8%,62.5% and 71.1%,82.2%,77.8%,75.6%,respectively.The coincident rate between ROC curve and results of postoperative pathological examination of CA 19-9,CA 125,CA242 and CA211 were 68.1% (47/69),76.8%(53/69),75.4%(52/69),71.0%(49/69),respectively.Conclusion The levels of serum CA19-9,CA125,CA242 and CA211 can effectively predict lymph node metastasis of patients with ICC.
