Background/Aims:
We investigated changes in recurrence rates and significant recurrence predictors over time after complete cure of hepatocellular carcinoma (HCC).
Methods:
A total of 1,491 patients with first-time diagnosis of Barcelona Clinic Liver Cancer stage A HCC, completely cured by treatment between 2007 and 2016, were recruited from two Korean tertiary institutes.
Results:
The mean age of the population (1,144 men and 347 women) was 58.6 years. Of the total population, 914 patients (61.3%) had liver cirrhosis. Nine-hundred and forty-one (63.1%) and 550 (36.9%) patients were treated with surgical resection and radiofrequency ablation (RFA), respectively. One-year cumulative incidences of HCC recurrence were 14.3%, 9.9%, and 5.1% from the time of treatment, 3 years after treatment, and 5 years after treatment, respectively. Upon multivariate analysis, multiple tumors, maximal tumor size ≥3 cm, and high Model for End-Stage Liver Disease scores were independently associated with increased HCC recurrence risk from the time of treatment and 1 and 2 years after curative treatment (all p<0.05, except for maxi-mal tumor size ≥3 cm for recurrence 2 years after treatment). Meanwhile, liver cirrhosis and RFA were independently associated with the increased HCC recurrence risk for almost all time points (liver cirrhosis: all p<0.05; RFA: all p<0.005 except for recurrence from 5 years after treatment).
Conclusions
The recurrence rate of HCC after curative treatment gradually decreased over time. Two years after treatment, when tumor-related factors lose their prognostic implications, may be used as a cutoff to define the boundary between early and late recurrence of HCC.

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a potentially life-threatening but reversible autoimmune disorder characterized by psychiatric symptoms, cognitive dysfunction, speech dysfunction, seizures, movement disorder, decreased level of consciousness, and autonomic dysfunction or central hypoventilation. It occurs predominantly in young women and approximately half of them have underlying tumors, mainly ovarian teratoma. A 24-year old woman was admitted because of fever, headache, abnormal movement and decreased mental status. Five cycles of plasmapheresis improved her neurological and mental status. Anti-NMDAR antibodies in her CSF and serum were positive, and computed tomography revealed a 1-cm sized mass suggestive of mature cystic teratoma arising from the right ovary. We promptly performed laparoscopic right ovarian cystectomy. She was discharged after 2 weeks with mild memory deficit. Prompt removal of ovarian teratoma and multidisciplinary care are particularly important for good outcome.

Inflammatory myofibroblastic tumor (IMT) is an uncommon mesenchymal solid tumor commonly documented in children and young adults. Here, we report a case of IMT in colon confirmed pathologically after laparoscopic anterior resection. A 35-year-old man presented with anal bleeding after defecation for 2 weeks. Colonoscopy demonstrated a mass with shallow ulceration in the central area and irregular margin accompanied by intact mucosa in the descending colon. Computer tomography showed a well-demarcated and homogenous solitary mass in the descending colon. We performed laparoscopic anterior resection. This case was diagnosed as IMT after microscopic examination. The tumor was composed of a proliferation of spindle-shaped cells arranged in the hyaline material with chronic inflammatory cells, composed mainly of plasma cells and lymphocytes. Immunohistochemically, tumor cells were positive for smooth muscle actin, and vimentin, and negative for desmin, CD117 (c-kit), anaplastic lymphoma kinase-1.

PURPOSE: The purpose of this study is to evaluate the effects of a local community based multi-factorial program for high-risk younger and older elderly people. METHODS: The quasi-experimental research design (pretest-post test) was employed. Participants were recruited in Seoul and a total of 98 elders completed an 8-week multi-factorial program for preventing frailty. Descriptive statistics, chi2-test and GLM were used in the data analysis with SPSS/WIN 15.0. RESULTS: The high-risk elderly people in the younger and older stages showed differences in IADL, TUG and BMI, and after being provided with the multi-factorial program for preventing frailty, some effects were shown on improving the total score of frailty, a physical function, TUG, BMI, depression, subjective feeling of health, and social interaction. CONCLUSION: The 8-week multi-factorial program for preventing frailty had positive effects on improving physical, emotional and social functions of the high-risk elderly people. It is necessary to evaluate the effects after individual intervention as well as group intervention and to evaluate the effects of the program by setting a control group in the future.

BACKGROUND/AIMS: We investigated the durability of the biochemical and virologic responses after adefovir (ADV) discontinuation in lamivudine-resistant (LMV-R) chronic hepatitis B (CHB) patients, and the outcomes of ADV discontinuation compared to that of ADV maintenance. METHODS: The indication for ADV treatment cessation was an undetectable level of hepatitis B virus (HBV) DNA documented on two occasions at least 6 months apart. All patients received additional ADV for at least 12 months after the confirmation of undetectable HBV DNA (Cobas TaqMan PCR assay, <70 copies/mL). Of 36 patients who had a sufficient ADV therapeutic effect, 19 discontinued ADV treatment, while the others maintained it. A virologic rebound was arbitrarily defined as the redetection of HBV DNA at a level higher than 105 copies/mL. RESULTS: In the ADV discontinuation group, ADV treatment and additional therapy were administered for medians of 33 months (range, 12-47 months) and 18 months, respectively. The patients were followed for a median of 12 months (range, 3-30 months) after ADV cessation. During that period, 18 of 19 patients (95%) experienced viral relapse. Viral rebound was observed in six patients (32%). However, 12 of 18 patients (67%) exhibited serum HBV DNA levels of less than 105 copies/mL. Biochemical relapses were observed in four of the six patients with viral rebound. In the ADV maintenance group, patients were treated for a median of 53 months (range, 31-85 months), and 9 patients (53%) experienced viral breakthrough. CONCLUSIONS: During short-term follow-up after ADV discontinuation, most patients (95%) exhibited viral relapse, whereas and viral breakthrough occurred in about half of patients (53%) maintained on ADV therapy. Therefore, the durability of virologic response after ADV discontinuation in LMV-R patients was unsatisfactory. In addition, and viral breakthrough was not infrequent in the ADV continuation group.

PURPOSE: This study was done to investigate factors affecting perceived financial burden of medical expenditures. METHOD: The participants were 2,024 inpatients who were enrolled in a survey on the benefit coverage rate of the National Health Insurance in 2006. The collected data were analyzed using t-test, ANOVA-test, Mann-Whitney-test, Kruskal-Wallis-test, Chi-square test and logistic regression. RESULTS: The crucial factors for perceived financial burden were age, job, equivalence scale, ratio of annual family income vs medical expenditure, and private health insurance. Perceived financial burden was higher for people who were older, who were unemployed, whose medical expenditures were high compared to annual family income, whose index of family equalization was low and for those who had no private health insurance. CONCLUSION: The results of the study indicate a demand for system reform that will enable management of no-pay hospital bills in the National Health Insurance to decrease the medical expense of people in the low-income bracket.

BACKGROUND: The grey zone of cervical cytology, and in particular atypical squamous cells, cannot exclude HSIL (ASC-H) causes diagnostic difficulties and increases medical expenses. We analyzed p16INK4a expression in ASC-H liquid-based cytology specimens (LBCS) to develop more effective methods for the management of ASC-H patients. METHODS: We carried out p16INK4a immunostaining with 57 LBCS of ASC-H diagnostic categories, all of which were histologically cofirmed and 43 cases of which were compared with the results of a human papillomavirus (HPV) chip test. RESULTS: p16INK4a immunostaining with ASC-H LBCS was positive in 20% (3/15) of cervicitis, 25.0% (3/12) of tissue-low-grade squamous intraepithelial lesion, 75.0% (18/24) of tissue-high grade squamous intraepithelial lesion (HSIL), and 100% (6/6) of invasive cancer cases. The positivity of p16INK4a in LBCS was correlated with higher grade of histologic diagnosis (r=0.578, p=0.000). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of p16INK4a immunostaining for the prediction of tissue-HSIL+ were 80.0%, 77.8%, 80.0%, and 77.8%, respectively. The sensitivity, specificity, PPV, and NPV of p16INK4a immunostaining plus HPV chip test for predicting tissue-HSIL+ were 71.2%, 86.4%, 84.2%, and 79.2%. CONCLUSIONS: p16INK4a immunostaining as well as HPV chip testing with remaining LBCS with ASC-H are useful objective markers for the prediction of tissue-HSIL+.

BACKGROUND/AIMS: The findings of several recent studies suggest that antinuclear antibodies (ANAs) are frequently detected in patients with acute hepatitis A (AHA). However, the clinical significance of a positive ANA test remains uncertain. This study was performed to evaluate the clinical significance of ANAs in AHA patients. METHODS: All patients admitted with AHA were consecutively enrolled in this study. An ANA assay was performed by indirect immunofluorescence during hospitalization. ANA positivity was defined as an ANA titer > or =1:80. The peak international normalized ratio (INR), peak alanine aminotransferase (ALT) and peak bilirubin levels were assessed over the duration of the hospitalization, and the incidence of AHA complications was evaluated. RESULTS: A total of 422 patients were enrolled in this study (age, 31+/-7 years), of which 260 (61.6%) were men. ANAs were detected in 179 AHA patients (42.4%). The proportion of ANA-positive patients varied significantly with AHA status on the day of the ANA assay (4.7% during the prodromal period vs 52.1% during the icteric or recovery period, p<0.001) and sex (56.2% in women vs 33.8% in men, p<0.001). The ANAs became undetectable in all ANA-positive patients within 3 months. The incidence of complications, including mortality, fulminant hepatic failure, renal dysfunction, relapse, and cholestatic hepatitis, did not differ significantly between ANA-positive and ANA-negative patients. CONCLUSIONS: ANAs were detected frequently and transiently in patients with AHA, especially after their peak-ALT day. The presence of ANAs may not be associated with the clinical outcome of AHA, but simply with AHA status on the ANA assay day.

PURPOSE: The purpose of this study was to evaluate the B-mode sonographic and sonoelastographic features of high risk lesions of the breast. MATERIALS AND METHODS: From April 2009 to February 2010, 1390 patients with breast lesions underwent US-guided core-biopsy. Among them, 13 lesions were confirmed to be pure sclerosing adenosis by subsequent surgical excision or on imaging follow-up of more than 1 year. Two radiologists retrospectively analyzed the B-mode sonography according to the Breast Imaging Reporting and Data System classification. The sonoelastographic images were classified into 5 elasticity scores according to the Itoh classification and the strain ratio between the mass and the surrounding fat tissue was reviewed. We considered the sonoelastographic patterns to be suspicious for the case with a score of 4 and 5 and a strain ratio of more than a 2.24. RESULTS: The common B-mode sonographic features of sclerosing adenosis were an irregular shape (69.2%, 9 of 13), an indistinct margin (92.3%, 12 of 13), hypoechogenicity (76.9%, 10 of 13) and category 4A, a low suspicion of malignancy (61.5%, 8 of 13). The common sonoelastographic features were a score of 2 (42%, 6 of 13) and a strain ratio < 2.24 (69.2%, 9 of 13). CONCLUSION: Sclerosing adenosis showed suspicious B-mode sonographic findings, but it had benign sonolastographic features.
