Summary
Automated radiotherapy plans for cervical cancer offer improved target coverage and reduced organ-at-risk doses. These script-based plans are faster and preferred by clinicians, leading to clinical implementation.
Area of Science:
- Radiation oncology
- Medical physics
- Cancer treatment
Background:
- Radiotherapy planning for cervical cancer is complex and time-consuming.
- Manual plan creation can lead to variability and suboptimal dose distributions.
Purpose of the Study:
- To develop and validate fully automated, script-based radiotherapy treatment planning for cervical cancer.
- To compare automated plans against manually created clinical plans.
Main Methods:
- Retrospective analysis of 25 locally advanced cervical cancer patient plans.
- Development of a Python script for automated plan generation in RayStation.
- Quantitative (dose statistics, DVHs) and qualitative (blinded review) comparisons.
- Verification of plan delivery accuracy using Delta4 Phantom+.
Main Results:
- Automated plans demonstrated acceptable target coverage and significantly improved conformity.
- Reduced mean doses to organs at risk (OARs) by 0.6-1.9 Gy.
- 99% of automated plans were preferred or equal in quality to clinical plans.
- Automated plan generation time reduced by 4-10 times (30-45 min).
Conclusions:
- Script-based automated planning provides acceptable target coverage and superior OAR sparing.
- Automated plans are more conformal and preferred by clinicians.
- The developed script has been implemented for clinical use due to its efficiency and quality.
