Summary
A new semi-automatic workflow, STAMP, standardizes gynecologic (GYN) HDR brachytherapy planning. It efficiently creates comparable or improved treatment plans, reducing variability and planner reliance.
Area of Science:
- Medical Physics
- Radiation Oncology
- Brachytherapy
Background:
- Interstitial gynecologic (GYN) high-dose-rate (HDR) brachytherapy requires complex inverse planning.
- Current methods can lead to variability and depend heavily on individual planner expertise.
Purpose of the Study:
- Introduce STAMP (structure- and template-assisted multi-dose-level planning), a standardized semi-automatic inverse planning workflow.
- Enhance planning consistency and reduce reliance on planner expertise in GYN HDR brachytherapy.
Main Methods:
- STAMP utilizes predefined optimization structures and objective templates for inverse planning.
- Retrospectively applied to 30 GYN interstitial HDR brachytherapy patients.
- Plan quality assessed via OAR D2cc, CTV coverage, and dwell times, compared to clinical plans.
Main Results:
- STAMP plans required a median of 4 optimization iterations.
- Achieved comparable CTV coverage and met EMBRACE I OAR constraints.
- Demonstrated slightly improved OAR sparing with no significant differences in dosimetric metrics or dwell times.
Conclusions:
- A semi-automatic workflow for multi-dose-level inverse planning in GYN HDR brachytherapy was developed.
- STAMP efficiently generates noninferior inverse plans.
- The standardized workflow reduces planning variability.
