  • Purpose: Alpha-fetoprotein (AFP) is widely accepted as a useful tumor marker for diagnosis of hepatocellular carcinomas. On rare occasions, however, an abnormal elevation of serum AFP also has been reported in an adenocarcinoma of the gastrointestinal tract. We evaluated the influence of preoperative abnormal elevation of serum AFP (AFP positivity) on the prognosis of resectable gastric cancers. Materials and Methods: 812 gastric cancer patients, who were investigated for serum AFP before their operations and who underwent gastric resections with D2 or more extended lymph node dissection, were enrolled in the study. The survival rates were calculated by using the Kaplan-Meier method and were compared by using the log-rank test. A multivariate analysis was performed using the Cox proportional hazards model. Results: Fifty patients ($6.2\%$) were AFP positive (10.1. 4322.6 ng/ml). The survival rate of the AFP positive group was significantly lower than that of the AFP negative group ( $46.6\%\;vs.\;67.0\%$; P=0.0002). The depth of tumor invasion, the degree of regional lymph node metastasis, distant metastases, the TNM stage, the gross type, differentiation, the extent of gastric resection, and the curability of the surgery also significantly influenced survival. Multivariate analysis revealed that the depth of tumor invasion, the degree of regional lymph node metastasis, the curability of the surgery, and AFP positivity were independent prognostic indicators. Conclusion: Preoperative serum AFP can be used as an independent prognostic factor of resectable gastric cancer.

  • Primary mediastinal immature teratoma is a rare germinal tumor which includes various elements of mature teratoma, choriocarcinoma, yolk sac carcinoma, embryonal carcinoma, and seminoma in some proportions. The tumor is virtually restricted to young man and the response to surgery and radiotherapy are poor. Recently, we experienced a case of primary mediastinal immature teratoma with elevated serum [-HCG and [-fetoprotein in 18 years old man. The well-encapsulated mass, weighing 4.5 kg, was completely resected and then adjuvant combination chemotherapy was tried with Vincristine, Bleomycin, and Cisplatin. Radical excision of tumor and adjuvant chemotherapy would appear to produce better result than have been reported in other cases. The postoperative course was uneventful and the tumor markers were returned to normal range.

  • Sacrococcygeal teratoma (SCT) is an extragonadal germ cell tumor (GCT) that develops in the fetal and neonatal periods. SCT is a type I GCT in which only teratoma and yolk sac tumors arise from extragonadal sites. SCT is the most common type I GCT and is believed to originate through epigenetic reprogramming of early primordial germ cells migrating from the yolk sac to the gonadal ridges. Fetal SCT diagnosed in utero presents many obstetrical problems. For high-risk fetuses, fetal interventions (devascularization and debulking) are under development. Most patients with SCT are operated on after birth. Complete surgical resection is the key for tumor control, and the anatomical location of the tumor determines the surgical approaches. Incomplete resection and malignant histology are risk factors for recurrence. Approximately 10-15% of patients have a tumor recurrence, which is frequently of malignant histology. Long-term surveillance with monitoring of serum alpha fetoprotein and magnetic resonance imaging is required. Survivors of SCT may suffer anorectal, urological, and sexual sequelae later in their life, and comprehensive evaluation and care are required.

  • Objectives The objective of present study was to investigate the effect of Ojeoksangamibang ($W\check{u}j\bar{i}s\check{a}nji\bar{a}w\grave{e}if\bar{a}ng$) extract on recovery of liver function in carbontetrachloride ($CCl_4$)-exposed rat. Methods Male rats weighing $230{\pm}7.21g$ fed experimental diet for 1 week and 28 rats were divided into 4 groups. Each of 7 rats was devided into a control group and experimental groups. We fed a control group of rats a basal diet and administered normal saline (100 mg/kg, 1 time/1 day) for 3 weeks. And we fed each experimental group of rats basal diet and administered an extract of Ojeoksangamibang extracts (100 mg/kg, 200 mg/kg, 300 mg/kg, 1 time/1 day) for 3 weeks. We measured lipid of plasma and liver, concentration of proinflammatory cytokines ($IL-1{\beta}$, IL-6 and IL-10). Statistical analysis was done by one-way analysis of variance (ANOVA) and Duncan's multiple range test with significance level at p<0.05. Results Plasma a-fetoprotein (AFP) and total protein concentration showed a tendency to decrease in Ojeoksangamibang extract-treated groups. However, plasma albumin concentration showed no significant differences in all treatment groups. Activity of plasma Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) in the Ojeoksangamibang extract-treated groups, increased addition amount of Ojeoksangamibang extracts tended to decline. Alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and ${\gamma}$-glutamyl transferase (${\gamma}$-GT) activities showed a tendency to decrease in Ojeoksangamibang extract-treated groups, increased addition amount of Ojeoksangamibang extracts tended to decline. Concentration of plasma triglyceride and total cholesterol showed a lower value than that of control group. The liver $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ concentration were decreased, and IL-10 was increased in Ojeoksangamibang extract groups, compared to control group. Plasma $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ concentration were decreased, and IL-10 was increased in Ojeoksangamibang extract groups, compared to control group. Conclusions This study suggested that Ojeoksangamibang may alleviate liver inflammatory reaction induced by liver toxicity.

  • Objectives: Infections with hepatitis B, C, and D virus (HBV, HCV, and HDV) are a major public health problem and lead to serious complications such as cirrhosis and hepatocellular carcinoma. We aimed to determine the seroprevalence of hepatitis B surface antigen (HBsAg), anti-HCV, anti-HDV immunoglobulin G, alpha-fetoprotein (AFP), and dual and triple hepatitis virus infections in Mongolia. Methods: A total of 2313 participants from urban and rural regions were randomly recruited for this cross-sectional study. A questionnaire was used to identify the risk factors for hepatitis virus infections, and the seromarkers were measured using immunoassay kits. Results: Among all participants, the prevalence of HBV, HCV, and HDV was 15.6%, 36.6%, and 14.3%, respectively. The infection rates were significantly higher in females and participants with a lower education level, rural residence, older age, and a history of blood transfusion. HBV and HCV co-infection was found in 120 (5.2%) participants and HBV, HCV, and HDV triple infection was detected in 67 (2.9%) participants. The prevalence of elevated AFP was 2.7%, 5.5%, and 2.6% higher in participants who were seropositive for HBsAg (p=0.01), anti-HCV (p<0.001), and anti-HDV (p=0.022), respectively. Elevated AFP was more prevalent in participants co-infected with HBV and HCV (5.8%, p=0.023), HBV and HDV (6.0%, p<0.001), and triple-infected with HBV, HCV, and HDV (7.5%) than in uninfected individuals. Conclusions: Nearly half (49.8%) of the study population aged ≥40 years were infected with HBV, HCV, or HDV, and 22.4% had dual or triple infections.

  • Background : Many investigators have found transforming growth factor-${\beta}1$ (TGF-${\beta}1$) to be elevated in tumors. Changes in responsiveness to TGF-${\beta}1$ have been linked to malignant transformation, tumor progression and tumor regression. Many malignant cell lines of epithelial or hematopoietic origin are refractory to the antiproliferative effects of TGF-${\beta}1$. However, a little is known about the association of TGF-${\beta}1$ with progression of malignant tumor. Methods : In this study, we measured the plasma level of TGF-${\beta}1$ in various cancer patients and evaluated the utility of plasma TGF-${\beta}1$ as a possible tumor marker. Plasma TGF-${\beta}1$ levels were measured using enzyme-linked immunosorbent assay in cancer patients and normal controls. Carcinoembryonic antigen (CEA) and alpha-fetoprotein (AFP) as tumor marker were compared with TGF-${\beta}1$ in the aspects of sensitivity and specificity. Results : The mean of plasma TGF-${\beta}1$ levels was $1.219{\pm}0.834ng/ml$ in normal controls, $5.491{\pm}3.598ng/ml$ in breast cancer, $12.670{\pm}10.386ng/ml$ in lung cancer, $5.747{\pm}3.228ng/ml$ in hepatocellular carcinoma and $10.854{\pm}7.996ng/ml$ in cervical cancer. In comparison with CEA and AFP, TGF-${\beta}1$ is more sensitive. Conclusion : We conclude that the high levels of TGF-${\beta}1$ are common in the plasma of cancer patients. These results suggest that the plasma TGF-${\beta}1$ level can be a potent tumor marker in various cancer patients.

  • Background: Early diagnosis of hepatocellular carcinoma (HCC) is the most important step in successful treatment. However, it is usually rare due to the lack of a highly sensitive specific biomarker so that the HCC is usually fatal within few months after diagnosis. The aim of this work was to study the role of plasma nuclear factor kappa B (NF-${\kappa}B$) and serum peroxiredoxin 3 (PRDX3) as diagnostic biomarkers for early detection of HCC in a high-risk population. Materials and Methods: Plasma nuclear factor kappa B level (NF-${\kappa}B$) and serum peroxiredoxin 3 (PRDX3) levels were measured using enzyme linked immunosorbent assay (ELISA), in addition to alpha-fetoprotein (AFP) in 72 cirrhotic patients, 64 patients with HCC and 29 healthy controls. Results: NF-${\kappa}B$ and PRDX3 were significantly elevated in the HCC group in relation to the others. Higher area under curve (AUC) of 0.854 (for PRDX3) and 0.825 (for NF-${\kappa}B$) with sensitivity of 86.3% and 84.4% and specificity of 75.8% and 75.4% respectively, were found compared to AUC of alpha-fetoprotein (AFP) (0.65) with sensitivity of 72.4% and specificity of 64.3%. Conclusions: NF-${\kappa}B$ and PRDX3 may serve as early and sensitive biomarkers for early detection of HCC facilitating improved management. The role of nuclear factor kappa B (NF-${\kappa}B$) as a target for treatment of liver fibrosis and HCC must be widely evaluated.
