NCT ID: NCT06450613 Completed - Cost Effectiveness Clinical Trials

Cost-effectiveness of RFA vs. PEI for Early-stage HCC

Start date: January 1, 2018
Phase: N/A
Study type: Interventional

Introduction: Liver transplantation(LT) is the gold-standard treatment for unresectable early-stage HCC within the Milan criteria. However, long waiting time can lead to dropout from LT candidacy. Local ablative procedures play a key role in the patient care enabling downsizing. Radiofrequency ablation(RFA) and percutaneous ethanol injection(PEI) are two valuable non-surgical neoadjuvant alternatives, but the most cost-effective treatment strategy remains controversial. Purpose: to assess whether RFA is cost-effective compared to PEI in adult patients with early-stage hepatocellular carcinoma within the Milan criteria. Methods: a pilot, single-center, randomized, open-label trial, with blinded end-point assessment, in which PEI was compared with RFA. Patients with early-stage hepatocellular carcinoma within the Milan criteria, listed for LT and indication for neoadjuvant treatment were eligible for enrollment. The primary outcome was the complete response rate according to mRECIST criteria at 60 days after the treatment. Secondary outcomes were the costs, rates and degrees of complications and the cost-effectiveness analysis of both techniques.

NCT ID: NCT03928457 Active, not recruiting - Preterm Infant Clinical Trials

Impact of Chronic Exposure to Radiofrequency Electromagnetic Fields on Neurophysiological Development in the Preterm Neonate

NeuroPrem-RF
Start date: April 1, 2019
Phase: N/A
Study type: Interventional

The massive use of highly technological devices in Neonatal Intensive Care Units may expose preterm neonates to electromagnetic fields, especially radiofrequencies, at low doses but continuously and chronically. Strikingly, the effect of long-term exposure to radiofrequencies on the neurophysiological development of preterm neonates has never been studied so far. The only studies on the impact of chronic exposure to radiofrequencies have been conducted in animals or adult humans, whereas preterm infants may be particularly vulnerable due to increased penetration of radiofrequency waves into the brain during a crucial period of neurodevelopment. The present project will aim at 1) quantifying individual levels of chronic exposure (during 6 weeks) to which preterm neonates are subjected during their stay in the Neonatal Intensive Care Unit, 2) following the evolution of the thermal environment and of the clinical parameters of the neonates after birth, 3) identifying potential alterations of neurophysiological activity (sleep, cerebral hemodynamics, autonomic nervous activity) which will be correlated to actual levels of chronic RF-EMF (radiofrequency electromagnetic fields) exposure.
