[Follow-up imaging in children with rhabdomyosarcoma: less scans, the same yield]

Area of Science:

• Pediatric Oncology
• Radiology
• Clinical Trial Design

Background:

• Children with rhabdomyosarcoma undergo regular follow-up imaging to detect relapses.
• The clinical utility of frequent imaging in rhabdomyosarcoma follow-up requires evaluation.

Purpose of the Study:

• To assess the clinical value of radiologic imaging in detecting rhabdomyosarcoma relapse.
• To inform updated follow-up guidelines for pediatric rhabdomyosarcoma patients.

Main Methods:

• Retrospective analysis of imaging and clinical data in rhabdomyosarcoma patients.
• Evaluation of relapse detection rates via imaging versus clinical symptoms.
• Development and implementation of a new follow-up protocol.

Main Results:

• The majority of rhabdomyosarcoma relapses were detected through clinical symptoms, not imaging.
• Frequent imaging protocols showed limited additional diagnostic value for relapse detection.
• A revised follow-up guideline was successfully implemented, reducing imaging frequency by 50%.

Conclusions:

• Clinical surveillance is paramount for rhabdomyosarcoma relapse detection in children.
• Reduced frequency of imaging in follow-up protocols is feasible and effective.
• Updated European guidelines now incorporate these findings, optimizing patient care and resource allocation.
