Therefore, the purpose of our study was to explore the diagnostic value of D-dimer in distinguishing between gallbladder carcinoma and benign controls.Methods: We retrospectively included age and gender-matched patients with gallbladder carcinoma and benign gallbladder lesions, and analyzed the diagnostic value of inflammatory markers, D-dimers, and tumor biomarkers by receiver operating characteristic curves (ROC).Results: The area under the ROC curve of white blood cells (WBC), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), D-dimer, alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), and carbohydrate antigen 19– 9 (CA19-9) were 0.600, 0.760, 0.729, 0.849, 0.502, 0.699, and 0.802, respectively. The combined diagnostic value of D-dimer and CA19-9 was 0.920, which was superior to other joint indicators.Conclusion: Serum D-dimer may be considered as a potential biomarker for detection of GBC. Moreover, the combined diagnosis of D-dimer and CA19-9 has excellent diagnostic value in gallbladder carcinoma.Keywords: D-dimer, CA19-9, diagnosis, gallbladder carcinoma
