Insights

Children aged 5 and older can successfully perform deep inspiration breath-hold (DIBH) for radiation therapy. This technique is feasible and safe for pediatric patients, with high compliance rates observed in a pilot study.

Area of Science:

  • Pediatric Oncology
  • Radiation Therapy Physics

Background:

  • Deep inspiration breath-hold (DIBH) is recommended for adults with mediastinal lymphoma to reduce heart and lung irradiation.
  • No previous studies have evaluated DIBH feasibility and compliance in pediatric patients.

Purpose of the Study:

  • To investigate the feasibility and compliance of DIBH in children aged 5 years and older.
  • To assess the suitability of DIBH equipment and coaching for pediatric use.

Main Methods:

  • A pilot study involving 33 children (18 healthy, 15 with cancer) aged 5-15 years.
  • Children underwent a DIBH training session, with voluntary breath-holds monitored by an optical surface system.
  • Compliance was defined as performing 3 stable 20-second DIBHs while remaining motionless.

Main Results:

  • 85% (28/33) of children were DIBH compliant, with 20 immediately compliant and 8 conditionally compliant.
  • Hospitalized children showed high compliance (14/15), and only one child could not grasp the DIBH concept.
  • DIBH equipment was suitable for children, and 94% reported satisfaction with training and the procedure.

Conclusions:

  • Children aged 5 and older can potentially comply with DIBH, performing stable and reproducible breath-holds for radiation therapy.
  • Custom-made immobilization and adequate training may further enhance DIBH compliance in pediatric patients.
  • A prospective clinical trial is underway to evaluate the dosimetric benefits of DIBH in pediatric patients.
