Abstract

Current guidelines advocate percutaneous radiofrequency (RF) ablation as a standard treatment of early stage hepatocellular carcinoma (HCC) for up to three tumors ≤3 cm in diameter. The local efficacy evaluated with short-term radiological examination may be overrated, whereas that assessed by histopathological measure might be underestimated. Long-term clinical follow-up studies guarantee the effectiveness of RF ablation for small HCC, which is now almost comparable in benefits to surgical resection. US is the most common guiding modality for percutaneous RF ablation for small HCC. However, the technical feasibility is often limited due to poor conspicuity of the index tumor on US. Implementation of artificial ascites, contrast-enhanced harmonic US, and fusion imaging of US with CT/MR can be helpful to enhance the technical feasibility of US-guided RF ablation of small HCC.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
