چکیده

We investigated changes in highly sensitive lens culinaris agglutinin A-reactive fraction of alpha-fetoprotein (hsAFP-L3) measured using a novel method and its predictive ability for prognosis in patients with hepatocellular carcinoma (HCC) who underwent curative hepatectomy, comparing to other HCC tumor markers, that is, AFP, des-gamma-carboxy prothrombin (DCP), and AFP-L3 measured with conventional method (cAFP-L3). AFP, DCP, and AFP-L3 including both cAFP-L3 and hsAFP-L3 were measured before and after curative hepatectomy in 187 patients. The percentage of patients with elevated tumor marker levels pre- and postoperatively was compared, and recurrence-free and overall survival rates were analyzed based on changes in tumor markers. The percentages of patients with elevated AFP, DCP, and cAFP-L3 decreased postoperatively. In contrast, the percentage of patients with elevated hsAFP-L3 did not decrease postoperatively. Both recurrence-free and overall survival rates were significantly lower in patients whose tumor marker levels remained elevated postoperatively than patients without tumor marker elevation postoperatively. Recurrence-free and overall survival rates of patients in whom hsAFP-L3 became elevated postoperatively despite normal preoperative hsAFP-L3 levels were significantly lower than those of patients with normal hsAFP-L3 postoperatively, and were similar to those of patients with persistent elevation. Preoperative elevations of AFP, DCP, and cAFP normalized in many patients postoperatively, but not for hsAFP-L3. The elevation of hsAFP-L3 identifies patients with poor prognosis despite the normalization of AFP and DCP.

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...

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...

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...

Cytomorphological Patterns of Nodular Lesions of Liver

Background and Objectives: Nodular lesions of liver are usually neoplastic (primary or metastatic), although inflammatory lesions can occur. The objectives of this paper were to study the cytomorphological changes in various nodular lesions of liver and to correlate the cytomorphological findings with biochemical parameters especially serum alpha-fetoprotein. Materials & Methods:  A cross-sect...

High expression of CXCR7 combined with Alpha fetoprotein in hepatocellular carcinoma correlates with extra-hepatic metastasis to lung after hepatectomy.

The lung is the most frequent metastatic site of hepatocellular carcinoma (HCC), negatively impacting on survival rates. In this study, we evaluated the prognostic role of the chemokine receptor CXCR7 in lung metastasis of HCC after hepatectomy, using immunohistochemical detection on tissue microarrays of HCCs, with and without lung metastasis. Using three categories based on staining character...
