چکیده

Methods Thirty-seven patients with HCC treated by RFA were evaluated. Lesion number, size and segmental location, T2-weighted (w), arterial, portal-venous and venous contrast-phase, b600 diffusion-w imaging (DWI) and delayed phase contrast-enhanced imaging pattern were assessed at MRI. The separate imaging patterns as well as pretreatment clinical variables were correlated with outcome (disease free survival longer or shorter than 1 year) using a chi-square test with multiple variables and Mann-Whitney U test respectively. Pretreatment clinical variables and imaging parameters were correlated with Keratin 19 and microvascular invasion status at the biopsy during RFA.

Comparing PET metabolic parameters with clinicopathological factors in predicting onset of early recurrence in recently diagnosed hepatocellular carcinoma

Introduction: Early recurrence of hepatocellular carcinoma (HCC) is a major risk factor affecting survival even after hepatectomy. Many clinical, biochemical parameters and pathological grading like fibrosis 1 index have been used for risk stratifying HCC. However not many studies have combined all of them. It is therefore important to risk stratify HCC especially with newer PE...

Status of serum alpha feto-protein (AFP) and midkine (MDK) levels in patients with hepatocellular carcinoma

Introduction: Hepatocellular carcinoma (HCC) is sixth common cancers worldwide and predominant in Asia and Africa. A number of evidence suggests a possible role of midkine (MDK) and α-fetoprotein (AFP) in the pathogenesis of hepatocellular carcinoma (HCC). Materials and methods: We studied MDK and AFP in patients with HCC or in healthy controls. MDK and AFP was measured by enzyme linked immuno...

Evaluation of serum AFP (α-fetoprotein) level in HBsAg carrier patients for diagnosis of hepatocellular carcinoma

Background: Hepatocellular carcinoma (HCC) is common all over the world as well as Iran. The incidence of HCC is higher in hepatitis B carriers and it is highly recommended to periodically screen these patients by serum alpha-fetoprotein (AFP) and liver ultrasound (US) every 6 months. We explore the diagnostic accuracy and the performance of (AFP) in cases of hepatitis B carriers as a scree...
