Management of Biliary Cystic Tumors (original) (raw)

Objective-To characterize clinical and radiological features associated with biliary cystic tumors (BCTs) of the liver, and to define recurrence-free and overall survival. Background-Biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCAC) are rare tumors that arise in the liver. Methods-Between 1984 and 2013, 248 patients who underwent surgical resection of BCA or BCAC were identified. Clinical and outcome data were analyzed. Results-Median total bilirubin, CA19-9, and carcinoembryonic antigen (CEA) levels were 0.6 mg/dL, 15.0 U/mL, and 2.7 ng/mL, respectively. Preoperative imaging included computed tomography only (62.5%), magnetic resonance imaging only (6.9%), or CT + MRI (18.5%). Features on cross-sectional imaging included multiloculation (56.9%), mural nodularity (16.5%),
