Abstract
ObjectiveTo analyze the clinicopathological features, immunohistochemical expression of well-differentiated hepatocellular carcinoma.
MethodsClinical data of 18 cases of well-differentiation hepatocellular carcinoma admitted to Dongyang People’s Hospital from March 2010 to June 2020 were retrospectively analyzed. All 18 patients underwent radical resection of hepatocellular carcinoma. Pathological examinations were performed on the surgically resected tissue samples, and the results of immunohistochemistry were interpreted.
ResultsUnder the microscope of 18 samples submitted for inspection, the cells were arranged into small beams and often had pseudoadenoid or acinar structures, and the cell level was greater than or equal to 3 layers. Immunohistochemical cytokeratin 7, cytokeratin 20 of 18 cases were negative, positive 18 cases of cytokeratin 8, positive 10 cases of glypican 3 (GPC3), positive 18 cases of clusters of differentiation 34 (CD34), showed a increase in number of tumor blood vessels, uniform distribution, positive 6 cases of CD10 capillary bile duct, the characteristic of trabecular, branching, and comma between cell staining, positive 5 cases of signal transducer and activation factor 3 (STAT3), positive 4 cases of alpha-fetoprotein, positive 7 cases of carcinoembryonic antigen.
ConclusionsPathological of well-differentiationhepatocellular carcinoma examination has certain characteristics but needs to differentiate from other benign and malignant liver tumors. Immunohistochemical CD34, GPC3 and STAT3 have certain specificity, combined application of a group of immunohistochemical antibodies is very helpful for the diagnosis of well-differentiated hepatocellular carcinoma.
