Background & Aims: The risk of hepatocellular carcinoma (HCC) in Caucasian patients with chronic hepatitis B (CHB), treated with entecavir (ETV) or tenofovir (TDF), is unclear. We evaluated the incidence and predictors of HCC and the accuracy of existing HCC risk scores in Caucasian CHB patients receiving ETV/TDF., Methods: This large, multicentre, retrospective cohort study included 1666 adult Caucasian CHB patients under ETV/TDF for 39 months. CHB without cirrhosis, compensated and decompensated cirrhosis were present in 67%, 39%, and 3% of patients, respectively. The predictability of baseline parameters and three risk scores (GAG-HCC, CU-HCC, and REACH-B), developed in Asian patients, was assessed., Results: The cumulative probability of HCC was 1.3%, 3.4%, and 8.7% at year-1, year-3, and year-5 after ETV/TDF onset. Older age and lower platelets were strong independent HCC predictors in the total population and in the subgroups of cirrhotic and non-cirrhotic patients, while liver disease severity was an independent HCC predictor in the total population and in the cirrhotics. GAG-HCC, CU-HCC, and REACH-B risk scores were associated with HCC development only in the univariable but not in the multivariable analyses and offered poor to modest predictability., Conclusions: HCC can still develop in Caucasian CHB patients treated with ETV/TDF. Besides the well-known predictors of HCC, such as older age, male gender and more advanced liver disease, lower platelets represent an independent factor of higher HCC risk. The applicability and predictability of HCC risk scores developed in Asian patients are poor or modest in Caucasian CHB patients, for whom different risk scores are required., (Copyright © 2014 European Association for the Study of the Liver.

Mediastinal tumors and cysts are relatively uncommon lesions requiring histologic confirmation. This retrospective study reports the experience of our department in the diagnosis and treatment of mediastinal lesions. Mediastinal lesions that were surgically treated in 200 patients aged 6-84 years, during a period of 28 years, were included in this series. Sixty patients had an apparently non-resectable lesion or lymphadenopathy of the anterior superior mediastinum. They had an anterior mediastinotomy and biopsy of the mediastinal lesion. No perioperative deaths were recorded in those patients. There were recorded 5 (8.3%) complications. Histological diagnosis was established in all patients: lymphoma (n = 21), metastatic carcinoma (n = 16), thymic lesions (n = 10), germ cell tumor (n = 3), other lesions (n = 10). The remainder 140 patients underwent a resection of the mediastinal lesion. One (0.7%) perioperative death and 21 (15%) complications were recorded. The histological diagnosis of the excised lesions was: thymic lesions (n = 60), neural tumors (n = 21), thyroid lesions (n = 14), bronchial cysts (n = 12), pericardial cysts (n = 10), germ cell tumors (n = 6), other lesions (n = 17). Our results are compared favorably with those reported in international literature. Surgery is the management of choice for patients with mediastinal lesions. It allows for establishing certain histological diagnosis and curative excision of the lesion, when it is necessary, with low operative risk.
