Filter by:Transarterial chemoembolization (TACE) is widely used for unresectable hepatocellular carcinoma (HCC). However, the hypoxia caused by TACE in surviving tumor cell leads to release of angiogenic and growth factors contributing to poor outcome. Sorafenib can block tumor cell proliferation and angiogenesis. The hypothesis is that patients with unresectable HCC may benefit from sorafenib in combination with TACE.
The purpose of this study is to determine whether liver transient elastography performed before the surgical procedure is able to predict liver failure in patients undergoing hepatectomy for hepatocellular carcinoma.
Hepatocellular carcinoma (HCC)is the most frequent primitive tumour of the liver. Recently, several research studies reported that 11C-choline PET has shown a high detection rate of well differentiated HCC, which is an early stage of primary liver cancer. The aim of this study was to prospectively evaluate the diagnostic accuracy of 11C-choline PET-CT to detect HCC in cirrhotic or non cirrhotic patients.
HCC (Hepato-cellular Carcinoma) is the fifth most frequent cancer in humans and its prevalence is growing. The most effective treatment of HCC is surgical and includes resection and liver transplantation; however, only 20% of the patients can be treated surgically. Local interventional therapy, such as radiofrequency (RF) ablation and transarterial embolization is also used. Recurrence rate is very high, and extrahepatic disease develops in about 30% of the cases and in up to 20% after liver transplantation. Systemic treatment is thus an option. Sorafenib (multi-kinase inhibitor) is the first agent to significantly improve the overall survival in advanced HCC. However, the drug has serious side effects and is very expensive. PET/CT with F18-FDG is a common tool for systemic evaluation and staging of various tumors. The value of the FDG PET for evaluation of HCC is controversial, in particular due to the unique metabolic pathway of glucose in the HCC cells. Since 2007 more and more studies suggest the feasibility of FDG PET/CT for monitoring local recurrence (especially after RF) and metastatic spread of HCC, including detection of active disease only suspected by AFP (alphafoetoprotein) elevation. Early detection of treatment response to therapy by whole body FDG PET/CT allows for change of treatment as early as possible,when the tumor is non-responsive before serious side effects appear or before depletion of body resources. The aim of our study is to investigate the contribution of FDG PET/CT to assessment of treatment response.
Persistent replication of HBV (47-55%) is frequently found in patients with HCC, which in turn leads to deterioration of liver reserve. Moreover, a large proportion of HCC patients who underwent curative therapy died from progressive liver decompensation rather than recurrence of cancer. It had been proved that anti-viral therapy for hepatitis C virus (HCV)-related HCC patients could reduce the rate of tumor recurrence after surgical resection. This is a prospective study to evaluate the efficacy of ETV therapy in chronic hepatitis B patients after receiving RFA therapy for HCC.
Prognostic impact of AR vs NAR
The purpose of this study is to evaluate 3 imaging techniques and their associations : MRI, CTscanner and enhanced contrast ultrasound for the diagnosis of small (< 3 cm) hepatocellular carcinoma for patients with cirrhosis.
