Clinical Trials planning meeting www.jco.org HCC © 2010 by the American Society of Clinical Oncology 3995 IMAGING AND EVALUATION OF tumor response to treatment are highly vascular HCC Ren tumors, preferably through the coast Of hepatic artery are supplied says the portal venous system t, which normally provides 70% of blood flow to the liver parenchyma. 21.22 Abdominal ultrasound is a simple, noninvasive, which h Frequently used in conjunction with Ma Took fetoprotein in the serum in the primary Ren screening of patients at high risk of developing HCC.
HCC tumors are well illustrated with the help of techniques four phases, and these tumors usually show contrast enhancement during the arterial phase and washout of contrast medium into the portal vein 25 phase.23 In the U.S., CT or MRI are the current modality Th for the The preferred imaging HCC.26 biomarker order AMG 900 most widely used, but at least when assessing response to treatment is to understand the Ver change of tumor size e-dimensional. The response evaluation criteria in solid tumors is h Used frequently to assess response to therapy. 27, 28 There are many Restrict Website will of dimensional Ma took, particularly in assessing the effect of targeted biological agents in solid tumors: Gr e measurements are a poor substitute for tumor volume, linear Ma took the tumor size s are difficult to reproduce fa is reliably permeable, and the size e do not take into account the biological effects of treatment.

Staging and prognosis of the cancer-SYSTEMS is an important prognostic tool that can help a classification system for guiding patient management, it provides a common language to compare the results of several clinical studies, and is essential for the rational design of clinical trials. Currently, no single classification system has been widely validated over the range of HCC patients, and none of the many systems was adopted globally.32 34 It is extremely difficult to give a clear, reproducible staging of HCC develop due to the considerable heterogeneity t of patients in connection with several underlying causes and the presence of either compensated or decompensated cirrhosis.35 On the basis of shared characteristics with several classification systems, the key factors share the impact solitary on the prognosis of HCC and selection of treatment option against Ren tumors are multifocal, the presence of extrahepatic invasion, makrovaskul Ren complications of the disease, increases hte serum AFP, the condition of the patient’s performance and the degree of liver failure.
