BACKGROUND/AIMS: α-Fetoprotein (AFP) is normally <10 ng/mL in adults without malignancy or liver regeneration. However, hereditary or nonhereditary persistence of AFP in healthy adults may be encountered in clinical practice. This study describes four cases of persistent AFP elevation in healthy adults and investigates mutations in key transcription regulatory regions of the AFP gene as potential drivers of AFP overexpression. METHODS: Four healthy adults with persistently elevated AFP levels (12.1 to 186.1 ng/mL) for >1 year, and 20 controls with low AFP levels (<0.61 to 2.9 ng/mL) were included in the study. AFP levels were collected from the families of two of the patients. We sequenced five regions that are critical for AFP expression: a promoter, two enhancers, and two silencers. RESULTS: One of the two cases in which family information was represented is the first case of hereditary persistence of AFP in South Korea. Mutations related to AFP overexpression were not found in the transcription regulatory regions among the four patients. CONCLUSIONS: Persistent AFP elevation is a heterogeneous condition with or without a hereditary pattern and may be caused by factors outside of transcription regulatory region changes. Further research on the mechanism of AFP elevation is needed.

PURPOSE: We evaluated oral metronomic capecitabine (MC) compared to intravenous doxorubicin in patients with advanced or metastatic hepatocellular carcinoma (HCC).METHODS: From January 2013 to December 2015, patients with Child-Pugh class A or early B were randomized either to MC group (500 mg twice daily continuously) or doxorubicin group (60 mg/m² every 21 days).RESULTS: Forty patients were included in each group. The baseline clinical characteristics of the enrolled patients were well balanced between the two groups. No complete response (CR) was reported in either group. In MC group, 2 patients (5%) had partial response (PR), 25 patients (62.5%) stable disease (SD) and 27 patients (67.5%) had disease control. In doxorubicin group, 4 patients (10%) achieved PR, 24 patients (60%) SD and 28 patients (70%) had disease control. The 6 months overall survival (OS) was 77.5% for MC and 75% for doxorubicin. The one year OS was 47.5% for MC and 42.5% for doxorubicin (P=0.521). The median OS survival was 10.2 months for MC and 9.6 months for doxorubicin (95% confidence interval, 3.2–6.5). The 6 month progression-free survival (PFS) was 45% for MC and 50% for doxorubicin. The one year PFS was 12.5% for MC and 7.5% for doxorubicin (P=0.289). The median time to progression was 3.4 months for MC and 3.1 months for doxorubicin. On multivariate analysis no significant impact for tumor stage, previous transhepatic arterial chemoembolization, portal vein thrombosis or median baseline alpha fetoprotein on OS.CONCLUSION: MC showed response rate and survival outcome comparable to doxorubicin in advanced HCC but with a more favorable toxicity profile.

BACKGROUND/AIMS: The prognosis after surgical resection of hepatocellular carcinoma (HCC) remains poor because of a high rate of recurrence. Thus, it is crucial to identify patients with a high risk of recurrence after curative hepatectomy and to develop more effective and targeted treatment strategies to improve disease outcomes. In this study, we investigated the roles of metadherin (MTDH) in the prognosis of HCC. METHODS: We investigated MTDH expression using immunohistochemistry in tumor tissue microarrays of 288 primary HCC patients who underwent curative surgical resection. RESULTS: High MTDH expression was observed in 138 of the 288 HCC cases (47.9%). High MTDH expression was associated with a younger age (p<0.001), higher Edmondson grade (p<0.001), microvascular invasion (p<0.001), higher American Joint Committee on Cancer T stage (p=0.001), and higher alpha-fetoprotein level (p=0.003). Multivariate analyses revealed that high MTDH expression (p=0.014), higher Barcelona-Clinic Liver Cancer (BCLC) stage (p<0.001), and Edmondson grade III (p=0.042) were independent predictors of shorter disease-free survival (DFS). Higher BCLC stage (p<0.001) and Edmondson grade III (p=0.047) were also independent predictors of shorter disease-specific survival. CONCLUSIONS: High MTDH expression may be a prognostic predictor of shorter DFS in HCC patients after curative hepatectomy.

We report herein a case of 72-year-old woman in whom liver metastasis of colon cancer was presented with a marked elevation of serum alpha-fetoprotein (AFP) level. She was transferred to our hospital for multiple liver masses found on ultrasonogram. Abdominal computed tomogram revealed multiple low-density masses in the liver and wall thickening of the hepatic flexure of colon. The serum AFP level was 10,718.8 ng/mL. Colonoscopic findings of ulcerofungating mass suggested liver metastasis from colon cancer. However, the possibility of combined hepatocellular carcinoma could not be ruled out due to serum AFP elevation. Both colon and liver biopsies revealed moderately differentiated tubular adenocarcinoma. Using an immunohistochemical staining, the adenocarcinoma in liver showed focal positive to AFP, but not in colon. This case represents a very rare case of colon cancer with a marked elevation of serum AFP.

OBJECTIVETo establish the median of serum markers for second trimester screening in Qingdao region and to assess the influence of median correction on the performance of screening.

METHODSMaternal serum alpha-fetoproteins (AFP), human chorionic gonadotrophin, free beta subunit (β -HCG) and unconjugated oestriol (uE3) were assayed for prenatal screening of 18 188 singleton pregnancies at 15-20(+ 6) weeks gestation from January 2009 to July 2010. The median of serum markers was calculated based on above results and applied for risk estimation in screening for fetal aneuploidy from August 2010 to March 2011. The screening performance, specified in terms of detection rates (DRs), false positive rates (FPRs) and odds of being affected given a positive result (OAPR) were compared between the two groups. The risks of 45 affected pregnancies detected during the study were estimated with both Caucasian and corrected medians.

RESULTSThe average level of AFP in local pregnancies was similar to that of the Caucasian population, whilst β -HCG and uE3 were respectively 11% and 33% higher than those of Caucasians. The multiple of median (MoM) value was between 0.94 and 1.02 for the dataset based on the corrected median. At a cut-off of l in 270, FPR has decreased from 5.2% to 4.9%, and DR of Down syndrome has increased from 60% to 69.2%, and OAPR has increased from 1:79 to 1:59 when evaluating risk based on the corrected median. For the 45 affected pregnancies, three Down syndrome pregnancies could be missed because their risk estimates were lower than the cut-off level based on Caucasian median.

CONCLUSIONIt is useful to establish and apply population and laboratory-specific medians in order to improve the performance of prenatal screening and diagnosis.

OBJECTIVETo evaluate the clinical significance of AFP-L3 in patients with hepatocellular carcinoma.

METHODSSerum AFP-L3 variants were separated by micro centrifugal column, and detected by chemiluminescence.

RESULTSAFP and AFP-L3 levels were higher in patients with hepatocellular carcinoma than those in patients with chronic hepatitis (P<0.001); as a diagnostic target, the sensitivity and specificity of AFP-L3 were 72.3 percent and 97.2 percent, respectively. Eight patients with hepatitis have higher AFP-L3, but none of them were found with carcinoma by CT three months later.

CONCLUSIONAFP-L3 is very useful in the diagnosis of patients with hepatocellular carcinoma.
