Bile duct invasion can be an independent prognostic factor in early stage hepatocellular carcinoma

BACKGROUNDS/AIMS: In hepatocellular carcinoma (HCC), bile duct invasion occurs far more rarely than vascular invasion and is not well characterized. In addition, the pathologic finding of bile duct invasion is not considered an independent prognostic factor for HCC following surgery. In this study, we determined the characteristics of HCC with bile duct invasion, and assessed the clinical significance of bile duct invasion. METHODS: We retrospectively reviewed the medical records of 363 patients who underwent hepatic resection for HCC at Seoul National University Hospital (SNUH) from January 2009 to December 2011. Preoperative, operative, and pathological data were collected. The risk factors for recurrence and survival were analyzed. Subsequently, the patients were divided into 2 groups according to disease stage (American Joint Committee on Cancer/International Union Against Cancer 7th edition): early stage (T1 and 2) and advanced stage (T3 and 4) group; and risk factors in the sub-groups were analyzed. RESULTS: Among 363 patients, 13 showed bile duct invasion on pathology. Patients with bile duct invasion had higher preoperative total bilirubin levels, greater microvascular invasion, and a higher death rate than those without bile duct invasion. In multivariate analysis, bile duct invasion was not an independent prognostic factor for survival for the entire cohort, but, was an independent prognostic factor for early stage. CONCLUSIONS: Bile duct invasion accompanied microvascular invasion in most cases, and could be used as an independent prognostic factor for survival especially in early stage HCC (T1 and T2).

The Effects of a Mobile Computerized System for Individual Tailored Home Care Services in a City

PURPOSE: The aim of this study was to evaluate the process and outcome of a mobile computerized system for individual home visiting healthcare. METHODS: A nonequivalent control group non-synchronized design was employed for this study. The newly constructed system was administered to 80 healthcare providers in the experimental group for 8 weeks. Data were analyzed using descriptive analysis, t-test, and ANCOVA with the SPSS 18.0 program. RESULTS: In the process stage, the difference in the frequency of computerized information usage between the experimental and control groups was significant as 8.88+/-3.20 and 7.08+/-2.92, respectively (t=3.90, p<.001). In the outcome evaluation stage, all kinds of healthy lifestyle such as alcohol use, nutrition, weight management and mental health were not improved. CONCLUSION: The findings of this study showed that the revised mobile computerized system was an effective device for individual visiting healthcare providers. Further advanced strategies for using this system should be developed and applied in a broad range of community healthcare.
