Summary
A new sleep-adjustment protocol (WASPE) significantly reduced the need for sedation during radiation therapy (RT) for young children. This approach met feasibility goals without compromising treatment accuracy or safety.
Area of Science:
- Pediatric Oncology
- Radiation Therapy
- Anesthesiology
Background:
- Radiotherapy (RT) in young children often requires pharmacologic sedation for immobilization.
- Sedation poses procedural burdens and potential adverse effects.
- The study evaluated a structured sleep-adjustment protocol (WASPE) to decrease sedation use during pediatric RT.
Purpose of the Study:
- To assess the feasibility and safety of the Wake-Adaptation Sleep Protocol for Evening (WASPE) in reducing sedation during pediatric radiation therapy.
- To determine the per-fraction rate of RT completion without pharmacologic sedation in the WASPE arm.
- To evaluate secondary endpoints including setup accuracy, intrafraction motion, and safety.
Main Methods:
- A single-center, randomized phase II feasibility trial enrolled children aged 0-4 years requiring RT for solid tumors.
- Patients were randomized 2:1 to the WASPE protocol or standard chloral hydrate sedation.
- All patients received image-guided intensity-modulated RT with cone-beam CT (CBCT) and optical surface monitoring (OSMS).
Main Results:
- The WASPE protocol achieved a 96.4% sedation-free RT completion rate, meeting the feasibility criterion.
- No significant compromise in CBCT-based setup accuracy or OSMS-based motion was observed.
- No grade ≥2 treatment-related adverse events occurred in either the WASPE or sedation groups.
Conclusions:
- The WASPE protocol is a feasible and safe method for delivering sedation-free radiation therapy in children under 4 years old.
- This approach met feasibility benchmarks without compromising positional accuracy or short-term safety.
- WASPE offers a promising alternative to routine pharmacologic sedation in pediatric RT.
