Infant and Child European Cryoablation Project ICECaP

This study collects data on children in Europe who undergo cryoablation — a procedure that uses extreme cold to destroy small tumors or abnormal tissue — as a medical treatment. Cryoablation is an alternative to surgery for certain types of tumors in children, but there is limited data on how well it works and how safe it is in pediatric patients across different countries and centers. The study is a registry — meaning researchers collect and track information about real patients receiving cryoablation as part of their clinical care. There is no experimental treatment; children who are clinically recommended for the procedure (or in whom it was tried but wasn't possible) are included. This registry will help build a better understanding of outcomes and guide future treatment guidelines for pediatric cryoablation. You may be eligible if: - You are under 18 years old - A clinical decision has been made to treat you or your child with percutaneous cryoablation You may NOT be eligible if: - You are 18 years or older Talk to your doctor to see if this trial is right for you.
