Objectives: studying the seroprevalence of HBsAg and anti-HCV in patients with hepatocellular carcinoma (HCC) and neoplasm of non-liver organs. Subjects and method: 124 patients with HCC and 284 patients with neoplasm of non-liver organs (i.e. stomach, colorectus and lung) were treated at Bach Mai Hospital and Viet Duc Hospital. This cross-sectional study was conductedfrom January 2002 to April 2003. Results: Out of 124 patients with HCC, HBsAg positive found in 95/124 (76.6%), anti- HCV positive found in 2/61 (3.28%), both HBsAg and anti-HCV posititive found in 1/61 (1.64%), and prevalence of anti-HCV is much lower than that of HBsAg, p<0.0001. Out of 284 patient with non-liver cancer, HBsAg posititive found in 33/284 (11.62%), and none among 179 patients has anti-HCV posititive. The prevalence of HBsAg posititive in HCC group is much higher than in non-liver cancer group (p<0.0001, OR=24.92).

Intra-cardiac extension of hepatocellular carcinoma (HCC) is an uncommon but serious condition related to poor prognosis. We report a 57-year-old male diagnosed with HCC with intra-cardiac extension into the right atrium at presentation. There were no symptoms related to cardiac involvement and intra-cardiac extension was incidentally noted on radiological imaging. He was offered palliative treatment and succumbed to his disease within 50 days of first diagnosis.

Review and update some knowledge of alpha feto-protein (AFP) value in the diagnosis, prognosis and management of patients with hepatocellular carcinoma (HCC), and the role of AFP in monitoring of response to medical and surgical treatments. Serum AFP tests give sensitivity of 50% and specificity >90% at cut-off value of 500 ng/ml in the diagnosis of HCC in patients who had underlined hepatic diseases

Sarcomatous hepatocellular carcinoma (HCC) is a rare primary liver cancer. Pathogenesis of sarcomatous transformation of HCC has not yet been elucidated. Sarcomatous HCC has highly invasive and metastatic potential, compared with ordinary HCC. We present here two cases of sarcomatous hepatocellular carcinoma with an unfavorable prognosis. Other cases reported in Korean literature of this uncommon tumor were also reviewed.

Gene expression of nm23 has been investigated in many kinds of tumors, including breast cancers, colon cancers, hepatocellular carcinomas, papillary carcinomas of the thyroid and malignant melanomas since the nm23 was dislovered by Dr. Steeg as a tumor metastatic suppressor gene. Reduced expression of nm23 gene implicated in high metastatic potential in a variety of malignancies. However, there have been only a few reports on genetic alteration and expression of nm23 in human gastric carcinomas even though gastric carcinoma is a leading malignancy in Korea. In this study, we examined the expression of nm23 protein by immunohistochemistry in advanced and early gastric carcinomas, adenomas, matching normal mucosa to elucidate the role of nm23 in the development, progression and metastasis of human gastric carcinomas. The results are as follows; 1) Nm23 was expressed in 39 cases(69.6%) of 56 advanced gastric carcinomas. Among them, strong positive cases(grade 3) were 26(46.4%) and weak positive cases(grade 2) were 13(23.2%). 2) Nm23 expression was significantly different (P<0.05) depending on the site of the neoplasm. Antral carcinomas showed grade3 positivity in the 22/37 cases(60%), but carcinomas of the body showed negative (grade 1) result in about half(42.1%). 3) Nm23 expression was more intense in the neoplasm than normal mucosa.(67.9%) 4) Nm23 expression was not significantly related to the lymph node metastasis, invasion of lymphatics or veins and depth of invasion. 5) In the well differentiated carcinomas, grade3 were more common(64.0%). But in cases of signet ring cell carcinoma, many cases were negative(50.0%). 6) Nm23 expression rate and intensity was significantly increased from the normal mucosa to the gastric adenomas, early gastric carcinomas and advanced gastric carcinomas.

In oncologic practice, treatment guidelines provide appropriate treatment strategies based on evidence. Currently, many guidelines are used, including those of the European Association for the Study of the Liver and European Organization for Research and Treatment of Cancer (EASL-EORTC), National Comprehensive Cancer Network (NCCN), Asia-Pacific Primary Liver Cancer Expert (APPLE), and Korean Liver Cancer Study Group and National Cancer Centre (KLCSG-NCC). Although radiotherapy is commonly used in clinical practice, some guidelines do not accept it as a standard treatment modality. In this review, we will investigate the clinical practice guidelines currently used, and discuss the application of radiotherapy.

A case of primary gastric carcinoma with patterns resembling those of hepatocellular carcinoma(HCC) is reproted. This patient who represented high serum alpha-fetoprotein(AFP) underwent a subtotal gastrectomy for stomach cancer and lobectomy of liver metastasis. The hepatoid component of the tumor was characterized by solid nests of large polygonal cells arranged in cords and trabeculae, with central nuclei, prominent nucleoli, and abundant eosinophilic cytoplasm; single-nuclear giant cells were frequently noted. These tumor cells of stomach stained positive immunohistochemically for AFP, ACT(alpha-1-antitrypsin), AACT(alpha-1-antichy-motrypsin). Thus, this hepatoid gastric adenocarcinoma tumor cells demonstrated both morphologic and immunohistochemical features of partial differentiation to the HCC. Careful histologic examination in conjunction with the immunohistochemical demonstration of AFP can provide a useful contribution to the diagnosis of this rare histological type of gastric carcinoma And the presence of metastatic hepatoid adenocarcinoma from the stomach should be considered in a patient with hepatic tumor mimicking HCC. Because of frequent venous and lymphatic invasion, as well as liver metastasis, prognosis appears to be poor. The authors reviewed 45 cases of hepatoid adenocarcinoma of stomach reported in the literature, also.
