Summary
A new comprehensive index using CEA, TBIL, and NLR effectively differentiates malignant from benign obstructive jaundice. This diagnostic tool improves accuracy in identifying cancerous causes of jaundice.
Area of Science:
- Hepatology
- Oncology
- Diagnostic Medicine
Background:
- Obstructive jaundice presents a diagnostic challenge in distinguishing benign from malignant causes.
- Accurate differentiation is crucial for timely and appropriate patient management.
Purpose of the Study:
- To develop and validate a comprehensive index for differentiating benign obstructive jaundice (BJ) from malignant obstructive jaundice (MJ).
Main Methods:
- Retrospective analysis of clinical data from 339 obstructive jaundice patients.
- Logistic regression analysis to build a prediction model.
- Model validation using a separate cohort.
Main Results:
- Carcinogenic Embryonic Antigen (CEA), Total Bilirubin (TBIL), and Neutrophil-to-Lymphocyte Ratio (NLR) were identified as independent factors for MJ.
- A comprehensive index incorporating CEA, TBIL, and NLR demonstrated high diagnostic performance.
- The model achieved 79.57% sensitivity and 93.26% specificity, with an Area Under the Curve (AUC) of 0.920.
Conclusions:
- The developed prediction model based on CEA, TBIL, and NLR offers a practical and effective method for differentiating malignant obstructive jaundice.
- This index can aid clinicians in improving diagnostic accuracy for obstructive jaundice.
