Potentially curative treatments for early‐stage hepatocellular carcinoma (HCC) have drawbacks and contraindications. Recently, radiotherapy has achieved good outcomes. We compared the outcomes of radiotherapy and radiofrequency ablation (RFA) for early‐stage HCC. Consecutive patients with ≤3 early‐stage HCC lesions and tumor diameters ≤3 cm treated with RFA or radiotherapy were reviewed. RFA was the first choice for HCC unsuitable for surgery. Otherwise, stereotactic body radiotherapy in five fractions was mainly performed. For HCC adjacent to the gastrointestinal tract, radiotherapy with mild hypofractionation was performed. Propensity score matching was performed to reduce the selection bias between the RFA and radiotherapy groups. Between 2012 and 2016, a total of 231 patients with 474 tumors and 143 patients with 221 tumors were eligible and were treated with RFA and radiotherapy, respectively. In an unmatched comparison, the 3‐year local recurrence rate was significantly lower for radiotherapy than for RFA (5.3%; 95% confidence interval [CI], 2.7‐9.2; versus 12.9%, 95% CI, 9.9‐16.2) (P < 0.01). A propensity score matching analysis of 106 patients in each group successfully matched the two treatment groups with regard to Barcelona Clinic Liver Cancer staging, T stage, and tumor size but not the adjacency of the tumor to risk organs or first or salvage treatment. The 3‐year overall survival rates for RFA and radiotherapy patients were comparable (69.1%; 95% CI, 58.2‐77.7; and 70.4%; 95% CI, 58.5‐79.4, respectively; P = 0.86). Conclusion: Radiotherapy has excellent local control and comparable overall survival in patients with well‐compensated liver function, exhibiting advantageous characteristics and compensating for the deficiencies of other treatment modalities; radiotherapy appears to be an acceptable alternative treatment option for patients who are not candidates for RFA.

We found different characteristics in the effects of aging and sarcopenia based on site and sex. We suggested that aging decreased tongue pressure more than jaw-opening force, and affected men more than women. Sarcopenia affected tongue pressure and jaw-opening force, with the exception of jaw-opening force in women. Considering these characteristics is useful to predict the decline of swallowing function, and provide appropriate interventions preventing dysphagia. Geriatr Gerontol Int 2017; 17: 295-301.

Background & Aims: The therapeutic mechanisms of ribavirin for hepatitis C are unclear. Microarray analyses have shown that ribavirin increases induction of interferon-stimulated genes (ISGs). We evaluated viral kinetics, serum cytokine expression, and viral mutagenesis during early stages of peginterferon therapy with and without ribavirin.

Contrast-enhanced wideband harmonic gray-scale US is a useful tool for differentiating among the hepatic tumors studied.
