    Abstract:
    BACKGROUND AND OBJECTIVES: Intrahepatic biliary cystadenoma and biliary cystadenocarcinoma are extremely rare neoplasms of the liver. They share similar radiological characteristics, and the clinicopathological features are poorly defined. We aim to provide an algorithm for preoperative differentiation of the two diseases. METHODS: Patients who underwent liver resection between May 2001 and May 2011 at Peking Union Medical College Hospital with biliary cystadenoma (20 cases) and biliary cystadenocarcinoma (10 cases) were reviewed. RESULTS: Significant differences were shown in age (P=0.030), gender (P=0.002) and symptom duration (P=0.012). Most biliary cystadenomas occurred in women ≤60 years old (85%), whilst most biliary cystadenocarcinomas occurred in older males (50%). Shorter symptom duration indicated a higher risk of biliary cystadenocarcinoma. Arterial blood flow and wall/nodule enhancement tended to be more common in biliary cystadenocarcinoma, but the difference was not significant (P=0.348). A score system was developed. The case-by-case validation and leave-one-out cross-validation showed an accuracy of 95.5% and 90.9%, respectively. The discriminative accuracy for cases from another hospital during the same period was 90.9%. CONCLUSIONS: Older age, male gender, and shorter symptom duration are associated with higher possibility of biliary cystadenocarcinoma. Location and blood supply by radiology might be instrumental but still need further verification.
