Conditions

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is a sub-study of the overall GUARDIAN trial (NCT04884802) in which some GUARDIAN trial participants will be additionally randomized to etomidate vs propofol for anesthetic induction.
