OBJECTIVES A case-referent study was conducted in the province of Trento, Italy, to investigate the possible association between occupational exposure and scleroderma (systemic and localized variants). METHODS Twenty-one cases of scleroderma were ascertained from the computerized admission files of all of the local hospitals from 1976 to 1991. For each(More)
A sensitive radioimmunoassay was used to detect antibodies to hepatitis C virus (HCV) in patients with hepatocellular carcinoma and chronic hepatitis. HCV antibodies (anti-HCV) were detected in 86 of 132 patients with hepatocellular carcinoma with no relation to the presence or absence of hepatitis B surface antigen (HBsAg). The prevalence of anti-HCV was(More)
One of the main regulatory pathways reported to be altered in hepatocellular carcinoma (HCC) is that of cell cycle control involving RB1 gene-related cell inhibitors. We investigated p14(ARF), p15(INK4B), p16(INK4A), p18(INK4C), and RB1 genes in a series of HCCs and associated cirrhosis with the goal of ascertaining their pattern of inactivation by gene(More)
BACKGROUND AND METHODS Patients with cirrhosis of the liver are recognized as being at risk for hepatocellular carcinoma. The magnitude of the risk, the natural history of this disease, and the possibilities for detecting potentially curable tumors in patients in the Western world are unknown. To address these questions, we examined 447 Italian patients(More)
BACKGROUND Sorafenib has shown survival benefits in patients with advanced hepatocellular carcinoma (HCC) and Child-Pugh (CP) class A liver function. There are few prospective data on sorafenib in patients with HCC and CP class B. PATIENTS AND METHODS A consecutive prospective series of 300 patients with CP class A or B HCC were enrolled in a dual-phase(More)
BACKGROUND The aetiological factors of hepatocellular carcinoma may vary over time. AIMS The study assessed the potential impact of the aetiological factors on the effectiveness of surveillance in real-world patients. METHODS Multicentre, cross-sectional study enrolling consecutive hepatocellular carcinoma cases during a six month period. RESULTS 1733(More)
A total of 1192 consecutive patients with diffuse liver disease were randomized to have percutaneous liver biopsy specimens taken with the Menghini or the Tru-Cut needle, to compare tissue yield, safety, and accuracy of the two needles for diagnosing cirrhosis. The sites of puncture were determined by prebiopsy ultrasound scans. Adequate samples were(More)
Sixty-six patients with hepatocellular carcinoma (HCC) in various stages of hepatic involvement were studied prospectively. Of these, 50 (75%) had associated cirrhosis and 19 (28%) had serum hepatitis B surface antigen (HBsAg). Six (9%) patients were eligible for tumor resection, 34 were selected for doxorubicin chemotherapy (60 mg/m2, i.v., given every 3(More)
BACKGROUND Thoracic duct dilation has been demonstrated in portal hypertension and hepatic cirrhosis by lymphangiography and laparotomy and at autopsy. It is thought to be secondary to increased hepatic lymph flow and has been described in the absence of ascites or esophageal varices. The aim of the present study was to observe thoracic duct morphology by(More)
Hepatitis C virus (HCV) is the major etiologic agent of parenterally transmitted non-A,non-B hepatitis. To determine whether there is a relationship between this virus agent and hepatocellular carcinoma (HCC), the sera of patients with HCC and chronic hepatitis were assessed using a sensitive immunoassay for HCV antibody. Anti-HCV was detected in 65% of 132(More)
