Abstract

PET is a highly specific tool in liver cancer diagnosis. However, in small hepatic lesions, typical imaging characteristics are lacking. The aim of this study was to investigate the accuracy of PET-CT and ultrasound-guided biopsy for diagnosis of liver carcinomas. Clinical data of 58 patients who were diagnosed and treated in our hospital from January 2008 to December 2012 were retrospectively reviewed. Before surgery, patients received PET-CT assessment, ultrasound examination, and ultrasound-guided biopsy of liver tissues. Forty three patients with cancer underwent partial hepatectomy. Clinical data were collected from hospital records and follow-up questionnaires. Postoperative histology revealed hepatocellular carcinoma in 26 patients (46.4%), liver metastases in 12 patients (21.4%). Only 4 patients (7.1%) had cholangiocarcinoma. The sensitivity of PET-CT, ultrasound, and ultrasound-guided biopsy for diagnosis of hepatocellular carcinoma (HCC) was 92.9%, 95.5%, and 100%, respectively. The surgery-related complication rate was 3.6%. Prognosis was good, with 1- and 3-year survival rates of 83.4% and 67.9%, respectively. PET-CT is highly specific for diagnosis of hepatic cancer, which is consistent with the diagnosis of ultras...Continue Reading
