Summary
This study introduces a flexible applicator method for intraoperative radiation therapy (IORT) to boost tumor dose and reduce relapse rates. The safe and effective flab technique is ideal for flat tumor beds, offering an alternative to rigid electron applicators.
Area of Science:
- Radiation Oncology
- Medical Physics
Context:
- Intraoperative radiation therapy (IORT) is a valuable tool in cancer treatment.
- Increasing the radiation dose to the tumor bed can improve outcomes.
- Existing IORT methods may have limitations in applicator flexibility.
Purpose:
- To develop and evaluate a novel method for intraoperative radiation therapy (IORT) using flexible applicators.
- To increase the radiation dose delivered to the tumor bed.
- To improve relapse rates by optimizing local tumor control.
Summary:
- A flexible plastic flab applicator system was developed for high-dose-rate afterloading IORT.
- The system allows for precise dose delivery to the tumor bed, accommodating various target volumes.
- Dose distributions were analyzed, considering applicator thickness, source positioning errors, and flab curvature.
Impact:
- The flab method for IORT is safe, easy to use, and has been successfully applied in over 150 cases.
- This technique enables dose escalation in challenging regions not easily treated with electron IORT.
- The rapid dose fall-off makes it particularly suitable for flat target volumes, such as tumor beds.
