Microwave ablation single-needle radiofrequency ablation for the treatment of HCC up to 4 cm: A randomized-controlled trial.

Background & Aims: Radiofrequency ablation (RFA) is the standard treatment for small hepatocellular carcinoma (HCC), specifically for tumors <3 cm in size and numbering fewer than three, excluding surgical candidates. Microwave ablation (MWA) is an innovative approach believed to have theoretical benefits over RFA; however, these advantages are yet to be empirically verified. Therefore, we evaluated and compared the effectiveness of MWA and RFA in managing HCC tumors up to 4 cm in size.

Comparative Analysis of Systemic Immune Responses and Metastatic Risks in Tumor Ablation: An Animal Study of Radiofrequency Ablation and Irreversible Electroporation with Immune Modulation.

Purpose: This study aimed to compare systemic immune responses and metastatic effects induced by radiofrequency ablation (RFA) and irreversible electroporation (IRE) in murine tumor models. We assessed cytokine production, growth of treated and untreated metastatic tumors, and synergy with immune checkpoint inhibitors (ICIs).

Materials And Methods: Hep55.

Impact of correlation structure on sample size requirements of statistical methods for multiple binary outcomes: A simulation study.

Background: In randomized clinical trials, multiple-testing procedures, composite endpoints, and prioritized outcome approaches are increasingly used to analyze multiple binary outcomes. Previous studies have shown that correlations between outcomes influence their sample size requirements. Although sample size is an important factor affecting the choice of statistical methods, the power and required sample sizes of methods for analyzing multiple binary outcomes have yet to be compared under the influence of outcome correlations.

Short-term outcomes in early term infants (born at 37 or 38 weeks): a retrospective investigation.

Introduction: Recently, researchers have introduced the concept of 'early term' infants, defined as infants born at 37 or 38 weeks of gestation, and their outcome has been discussed. Although the complications experienced by early term are less severe than those in preterm infants, this group accounts for a much larger proportion of newborns, making the assessment of outcomes important in clinical practice.

Methods: This observational study of term infants born at Tokyo Metropolitan Toshima Hospital aimed to understand the short-term outcomes in early term infants.
