چکیده
conclusions the findings of this study reveal that both arg-1 and gpc-3 are helpful ihc markers to separate hcc from cc and ma. furthermore, arg-1 shows 100% sensitivity and 82.6% specificity for the diagnosis of hcc whereas gpc-3 demonstrated 97.7% sensitivity and 91.3% specificity for the diagnosis of this tumor. results arginase-1 and gpc-3 demonstrated diffuse staining, as reactivity in > 97% of hccs, whereas only one (5.3%) and 2 (10.5%) of 19 cc cases show positive staining for gpc-3 and arg-1, respectively. the expression of both markers in ma showed 6 (22.2%) for arg-1 and 3 (11.1%) for gpc-3, especially with colorectal origin. our findings showed a statistically significant difference between arg-1 and gpc-3 expression in hcc, cc and ma. objectives the aim of this study was to determine the diagnostic accuracy of arg-1 and glp-3 in differential diagnosis of liver tumors. patients and methods eighty-nine formalin-fixed paraffin-embedded tissue blocks including 43 cases of documented hccs, 19 cases of documented cc, and 27 cases of ma involving the liver (15 colon, 5 stomach, 3 pancreas, 2 gallbladder, 1 duodenum and 1 ampulla of vater) were evaluated for immunohistochemical expression of arg-1 and gpc-3. background hepatocellular carcinoma is the most common primary liver cancer. pathologic distinction between hepatocellular carcinoma (hcc) and adenocarcinoma (cholangiocarcinoma (cc) and metastatic adenocarcinoma (ma)) can be challenging and sometimes requires immunohistochemical panels. recently, arginase-1 (arg-1) and glypican-3 (gpc-3) have been introduced for differentiation of these tumors.

Diagnostic Value of Arginase-1 and Glypican-3 in Differential Diagnosis of Hepatocellular Carcinoma, Cholangiocarcinoma and Metastatic Carcinoma of Liver
BACKGROUND Hepatocellular carcinoma is the most common primary liver cancer. Pathologic distinction between Hepatocellular Carcinoma (HCC) and adenocarcinoma (Cholangiocarcinoma (CC) and Metastatic Adenocarcinoma (MA)) can be challenging and sometimes requires immunohistochemical panels. Recently, Arginase-1 (ARG-1) and Glypican-3 (GPC-3) have been introduced for differentiation of these tumors...
متن کاملThe diagnostic value of arginase-1 immunostaining in differentiating hepatocellular carcinoma from metastatic carcinoma and cholangiocarcinoma as compared to HepPar-1
BACKGROUND The ability to distinguish hepatocellular carcinoma (HCC) from metastatic carcinoma (MC) involving the liver and cholangiocarcinoma (CC) by immunohistochemistry has been limited by the lack of a reliable positive marker for hepatocellular differentiation. Arginase-1 is a marker for HCC recently described in some literature. AIM To examine the immunohistochemical staining of arginas...

Background: The objective was to explore the value of the CT value difference (△HU) and CT value ratio (CVR) between the hepatic arterial (AP), portal (PP), and delayed phases (DP) to differentiate the small Hepatocellular Carcinoma (SHCC, ≤ 3 cm) from the small Focal nodular hyperplasia (SFNH, ≤ 3 cm). Materials and Methods: All the lesions were confirmed by clinically and/or pathologically an...
متن کاملDiagnostic value of glypican-3 in alpha fetoprotein negative hepatocellular carcinoma patients.
BACKGROUND The prognosis of patients with hepatocellular carcinoma(HCC) is generally very poor with a 5-year survival rate of less than 15% since most of them are diagnosed clinically at their late stage. However, the differential diagnosis between alpha fetoprotein(AFP) negative HCC and cirrhotic nodules is still difficult. OBJECTIVES To evaluate the diagnostic value of glypican-3(GPC3) in p...
