Angiogenesis is a crucial process contributing to tumor growth and metastasis. Recently, Rac has been suggested to play a role in angiogenesis. However, the actual role of Rac in HCC angiogenesis ... http://hepatocellular-cancer.com/2008/04/18/rac-activation-is-associated-with-hepatocellular-carcinoma-metastasis-by-up-regulation-of-vascular-endothelial-growth-factor-expression/ The incidence of hepatocellular carcinoma is increasing in many countries. The estimated number of new cases annually is over 500,000, and the yearly incidence comprises between 2.5 and 7% of patients with liver cirrhosis. The incidence varies between different geographic areas, being higher in developing areas; males are predominantly affected, ... http://hepatocellular-cancer.com/2008/04/18/epidemiology-risk-factors-and-natural-history-of-hepatocellular-carcinoma/ Hepatocellular carcinoma accounts for 80 - 90% of all liver cancers. This type of cancer occurs more often in men than women, usually in people 50 to 60 years old. The disease is more common in parts of Africa and Asia than in North or South America and Europe. The cause ... http://hepatocellular-cancer.com/2008/04/18/causes-incidence-and-risk-factors-of-hepatocellular-cancer/ Hepatocellular carcinoma: A tumor in which the cancer starts during adulthood in cells in the liver. Also called adult primary liver cancer. Primary liver cancer is different from cancer that has metastasized (spread) from another place in the body to the liver. The signs and symptoms may include a hard ... http://hepatocellular-cancer.com/2008/04/18/definition-of-hepatocellular-carcinoma/ Background: Because hepatic cirrhosis is a major risk factor for hepatocellular carcinoma, recent guidelines by the European Association for the Study of the Liver (EASL) on clinical management of hepatocellular carcinoma recommend periodic ultrasound surveillance of cirrhotic patients with immediate workup for nodules >1 cm; an increase in the frequency ... http://hepatocellular-cancer.com/2008/04/18/ultrasound-guided-fine-needle-biopsy-of-early-hepatocellular-carcinoma-complicating-liver-cirrhosis-a-multicentre-study/ PURPOSE: To evaluate the usefulness of power Doppler ultrasonography (US) with a microbubble contrast agent in assessing the therapeutic response of hepatocellular carcinomas (HCCs) treated with percutaneous radio-frequency (RF) ablation. MATERIALS AND METHODS: Forty patients with 45 nodular HCC lesions 1.0–3.8 cm in diameter underwent power Doppler US before and ... http://hepatocellular-cancer.com/2008/04/18/hepatocellular-carcinoma-treated-with-percutaneous-radio-frequency-ablation-usefulness-of-power-doppler-us-with-a-microbubble-contrast-agent-in-evaluating-therapeutic-response-preliminary-results1/ Hepatocellular carcinoma (HCC) is a major health problem worldwide. Currently, the only chance for obtaining a cure in patients with HCC is by either a surgical resection or liver transplantation. However, many HCCs with scattered tumors cannot be operated on. In such patients, effective alternative therapies need to be discovered ... http://hepatocellular-cancer.com/2008/04/18/hepatocellular-carcinoma-has-new-chemotherapeutic-target/ Abstract. The diagnosis of hepatocellular carcinoma (HCC) usually occurs at late stages in the disease when there are few effective treatment options. The measurement of the concentration of tumour markers in the serum of patients is a complementary tool frequently used for the interpretation of diagnostic imaging results. It is ... http://hepatocellular-cancer.com/2008/04/18/characterization-of-cirrhosis-and-hepatocellular-carcinoma-using-low-angle-x-ray-scattering-signatures-of-serum/ CASE HISTORY A 50-year-old man presented with a rapidly growing swelling over the sternum of two months duration. Except for this swelling, he had no other symptoms. Clinical examination revealed a 9 cm x 6 cm hard, fixed mass over the manubrium sterni. The overlying skin was erythematous with evidence of ... http://hepatocellular-cancer.com/2008/04/18/chest-wall-metastases-from-unknown-primary-hepatocellular-carcinoma/ Background: Patients with hepatitis C virus (HCV) are at increased risk for hepatocellular carcinoma. Although serum -fetoprotein (AFP) is often used to detect hepatocellular carcinoma in HCV-infected individuals, its utility is unclear. Purpose: To define the test characteristics of AFP for the diagnosis of hepatocellular carcinoma in patients with HCV. ... http://hepatocellular-cancer.com/2008/04/18/test-characteristics-of-fetoprotein-for-detecting-hepatocellular-carcinoma-in-patients-with-hepatitis-c/
