Abstract
Background Biliary stricture caused by malignant tumors is known as Malignant Biliary Stricture (MBS). MBS is challenging to differentiate clinically, and accurate diagnosis is crucial for patient prognosis and treatment. This study aims to identify the risk factors for malignancy in all patients diagnosed with biliary stricture by Endoscopic Retrograde Cholangiopancreatography (ERCP), and to develop an effective clinical predictive model to enhance diagnostic outcomes. Methodology Through a retrospective study, data from 398 patients diagnosed with biliary stricture using ERCP between January 2019 and January 2023 at two institutions: the First People's Hospital affiliated with Jiangsu University and the Second People's Hospital affiliated with Soochow University. The study began with a preliminary screening of risk factors using univariate regression. Lasso regression was then applied for feature selection. The dataset was divided into a training set and a validation set in an 8:2 ratio. We analyzed the selected features using seven machine learning algorithms. The best model was selected based on the Area Under the Receiver Operating Characteristic (ROC) Curve (AUROC) and other evaluation indicators. We further evaluated the model's accuracy using calibration curves and confusion matrices. Additionally, we used the SHAP method for interpretability and visualization of the model's predictions. Results RF model is the best model, achieved an AUROC of 0.988. Shap result indicate that age, stricture location, stricture length, carbohydrate antigen 199 (CA199), total bilirubin (TBil), alkaline phosphatase (ALP), (Direct Bilirubin) DBil/TBil, and CA199/C-Reactive Protein (CRP) were risk factors for MBS, and the CRP is a protective factor. Conclusion The model's effectiveness and stability were confirmed, accurately identifying high-risk patients to guide clinical decisions and improve patient prognosis.

[PMID: 35082529 PMCID: PMC8784971 DOI: 10.2147/cmar.s344711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2021] [Accepted: 01/10/2022] [Indexed: 11/25/2022] Open
Abstract
Objective To evaluate the predictive value of multiple serum tumor markers in hepatolithiasis complicated with intrahepatic cholangiocarcinoma (hepatolithiasis-associated cholangiocarcinoma, HL-CCA). Methods From January 2010 to December 2020, three hundred eighty-five hepatolithiasis patients in Zhoukou Central Hospital were retrospectively analyzed, among them thirty patients complicated with intrahepatic cholangiocarcinoma. The levels of serum AFP, CA125, CA19-9, CA242, and CEA in hepatolithiasis or HL-CCA were measured. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic effects of single or combined detection of the five tumor markers for HL-CCA. Results The level of AFP was insignificantly different between the hepatolithiasis and HL-CCA (P=0.730). CA125, CA19-9, CA242 and CEA were elevated in HL-CCA. The area under ROC curves (AUCs) of the single detection of serum CA125, CA19-9, CA242 and CEA were all more than 0.5. The maximum AUC occurred in CA19-9. The AUC of AFP was slightly higher than 0.5, but the level of serum AFP was insignificantly different between hepatolithiasis and HL-CCA. The single detection of AFP was not of great significance to the differential diagnosis. The optimal cut-off values of CA125, CA19-9, CA242, and CEA were 104.09 kU/L, 383.28 U/mL, 152.56 kU/L, 6.29 ng/mL. The diagnostic effect of CA19-9 was the highest one for differential diagnosis between hepatolithiasis and HL-CCA. With reference to CA19-9 >383.28 U/mL, the sensitivity and specificity of the single detection were 80.00% and 82.61% respectively, and the AUC was 0.883. The diagnostic effect of CEA was secondary toward CA19-9. With reference to CEA >6.29 ng/mL, the sensitivity and specificity of the single detection were 66.67% and 83.76% respectively, and the AUC was 0.814. Conclusion Serum CA19-9 maybe the effective tumor marker in the diagnosis of HL-CCA, and measurement of combined serum tumor markers can help in the detection of HL-CCA.

Abstract
Simple Summary Pancreatic cancer is the fourth most common cancer-related cause of death in the United States and is usually asymptomatic in early stages. There is a scarcity of tests that facilitate early diagnosis or accurately predict the disease progression. To this end, biomarkers have been identified as important tools in the diagnosis and management of pancreatic cancer. Despite the increasing number of biomarkers described in the literature, most of them have demonstrated moderate sensitivity and/or specificity and are far from being considered as screening tests. More efficient non-invasive biomarkers are needed to facilitate early-stage diagnosis and interventions. Multi-disciplinary collaboration might be required to facilitate the identification of such markers. Abstract Pancreatic ductal adenocarcinoma (PDAC) is the most common pancreatic malignancy and is associated with aggressive tumor behavior and poor prognosis. Most patients with PDAC present with an advanced disease stage and treatment-resistant tumors. The lack of noninvasive tests for PDAC diagnosis and survival prediction mandates the identification of novel biomarkers. The early identification of high-risk patients and patients with PDAC is of utmost importance. In addition, the identification of molecules that are associated with tumor biology, aggressiveness, and metastatic potential is crucial to predict survival and to provide patients with personalized treatment regimens. In this review, we summarize the current literature and focus on newer biomarkers, which are continuously added to the armamentarium of PDAC screening, predictive tools, and prognostic tools.

Abnormal serum carbohydrate antigen 19-9 levels in a patient with splenic retiform haemangioendothelioma concomitant with hepatic amyloidosis: A case report. World J Clin Cases 2020; 8:1108-1115. [PMID: 32258081 PMCID: PMC7103981 DOI: 10.12998/wjcc.v8.i6.1108] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Revised: 01/21/2020] [Accepted: 03/14/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Carbohydrate antigen 19-9 (CA 19-9) is a glycoprotein that is used as a reliable tool for monitoring pancreatic cancer. Serum CA 19-9 levels are increased in patients suffering from liver, lung, and other non-malignant diseases. Haemangioendothelioma is a vascular neoplasm with a borderline biological behaviour. However, no case of haemangioendothelioma has yet been reported to be associated with CA 19-9.
CASE SUMMARY A 54-year-old Chinese man was referred to our hospital for discontinuous fatigue and unintentional weight loss for over one year. Laboratory investigations revealed an elevated serum CA 19-9 concentration of 39 IU/mL (reference interval, 0–37 IU/mL) over one year before admission. Afterwards, coagulopathy appeared, and the patient’s serum CA 19-9 concentration increased continuously. At the time of admission, abdominal pain and haemorrhagic shock burst occurred, and emergency medical operation was performed. Laboratory investigations conducted upon admission showed a serum CA19-9 concentration of 392.56 IU/mL. Surgical resection of the spleen was undertaken, and pathological examination showed retiform haemangioendothelioma. The patient developed jaundice ten days after surgical excision of the spleen. Pathological examination of needle biopsy samples of the liver yielded a diagnosis of hepatic amyloidosis.
CONCLUSION We describe a rare case of splenic retiform haemangioenthelioma concomitant with hepatic amyloidosis. Physicians should note abnormal serum CA 19-9 levels with early symptoms of fatigue and unintentional weight loss.

Abstract
OBJECTIVE Acute pancreatitis (AP) is an important clinical event with an increased frequency due to increased life expectancy, obesity, and alcohol use. There are some data about the elevation of carbohydrate antigen (CA) 19-9 levels in benign and malignant pancreaticobiliary events in the literature, but in AP they are limited. The aim of this study was to evaluate the CA 19-9 level in patients with AP and determine its relationship according to the cause. METHODS Between 2010-2018, 173 patients evaluated with CA 19-9 levels as well as by standard laboratory tests were included in the study. CA 1 9-9 levels and laboratory findings were compared in patients with pancreatitis due to gallstone (group 1) and metabolic/toxic reasons such as hyperlipidemia, alcohol, or drug use (group 2). RESULTS There were 114 (66%) patients in the group 1 and 59 (34%) patients in the group 2. The majority of patients with high CA 19-9 level were in group 1 (92.1% vs 6.8%). CA 19-9 level, as well as amylase, lipase, AST, ALT and bilirubin levels were found to be statistically higher in patients with AP due to gallstone compared to patients with metabolic/toxic AP. CONCLUSIONS Patients with AP due to gallstone, were found to have a high level of CA 19-9 at admission. Early stage CA 19-9 levels may contribute to standard laboratory tests in the etiology of the disease in patients diagnosed with AP.

Differential diagnostic roles of the serum CA19-9, total bilirubin (TBIL) and the ratio of CA19-9 to TBIL for benign and malignant. J Cancer 2018; 9:1804-1812. [PMID: 29805707 PMCID: PMC5968769 DOI: 10.7150/jca.25093] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2018] [Accepted: 03/08/2018] [Indexed: 12/31/2022] Open
Abstract
Background: Obstructive jaundice is one of the most common symptoms which can be caused by both malignant and benign hepato-biliary-pancreatic diseases. The differences and the differential diagnostic roles of the serum CA19-9, total bilirubin (TBIL) and especially, the ratio of CA19-9 to TBIL in these patients have not been well elucidated. This study compared the differences and the differential diagnostic roles of the increase-folds of the serum CA19-9, TBIL and the ratio of increase-folds of CA19-9 to increase-folds of TBIL in 508 cases of malignant (MOJ) and benign (BOJ) obstructive jaundice patients. Methods: Totally, 508 cases of obstructive jaundice patients with pathological results were retrospectively enrolled. 342 cases were MOJ, including gallbladder adenocarcinoma, extrahepatic cholangiocarcinoma, periampullar adenocarcinoma and pancreatic adenocarcinoma.The other 166 cases were BOJ, including cholelithiasis, primary sclerosing cholangitis (PSC), IgG4 related sclerosing cholangitis (IRSD), inflammatory stricture of bile duct, and adenoma. The data of the increase-folds of serum CA19-9, TBIL and the ratio of increase-folds of CA19-9 to increase-folds of TBIL was collected and analyzed. The ROC (receiver operating characteristic) curve was adopted to determine the optimal cutoff value to evaluate their differential diagnostic roles. Results: The CA19-9 was elevated in 94.15% of the MOJ, compared to 67.10% in BOJ (P<0.0001). The increase-folds of the CA19-9 (76.52±15.04 vs 3.55±0.41, P< 0.0001) and the increase-folds of TBIL (7.10±0.25 vs 5.95±0.36, P=0.0034) and the ratio (14.96±5.05 vs 0.79±0.93, P=0.0026) in MOJ were significantly higher than BOJ. The ROC curves indicated that the TBIL showed minimal differential diagnostic power (AUC=0.590), the increase-folds of CA19-9 and the ratio showed stronger differential diagnostic power (AUC=0.815 and AUC=0.889, respectively). The optimal value of the increase-folds of serum CA19-9 and the ratio for differential diagnosis was 4.5 and 0.88, respectively. Further, the combination of the increase-folds of serum CA19-9 and the ratio could increase the specificity and accuracy of the diagnosis of MOJ. Conclusion: The serum CA19-9, TBIL and the ratio in MOJ and BOJ are significantly different. The ratio of the increase-folds of CA19-9 to increase-folds of TBIL has stronger differential diagnostic roles than the increase-folds of CA19-9 or TBIL alone. The combination of the increase-folds of the CA19-9 and the ratio can further improve the specificity and accuracy of the diagnosis of MOJ.
