The COllaborative Neonatal Network for the First CPAM Trial

The goal of this clinical trial is to compare conservative wait-and-see management to elective surgical intervention, in asymptomatic Congenital Pulmonary Airway Malformation (CPAM) children. Children assigned to the intervention group will undergo surgical resection of the CPAM between 6 and 9 months of age. Children assigned to the control group will be monitored conservatively. The follow-up scheme will be uniform for both treatment groups and last for 5 years. The primary outcome is the difference in maximal endurance at five years of age between the surgical and conservative group. Secondary outcome measures are molecular genetic diagnostics, validated questionnaires - on parental anxiety, quality of life and health care consumption -, repeated imaging, and pulmonary morbidity during follow-up, as well as surgical complications and histopathology.
