Summary
The hybrid tangential Volumetric Modulated Arc Therapy (T-VMAT) technique offers the best balance of quality, efficiency, and organ at risk (OAR) sparing for breast cancer radiotherapy.
Area of Science:
- Radiation Oncology
- Medical Physics
- Breast Cancer Treatment
Background:
- Accurate radiation delivery is crucial for breast cancer treatment.
- Simultaneous integrated boost (SIB) techniques aim to improve treatment efficacy.
- Evaluating dosimetric parameters of different SIB techniques is essential for optimizing patient outcomes.
Purpose of the Study:
- To perform a dosimetric comparison of various breast SIB techniques.
- To assess target volume coverage and doses to organs at risk (OARs).
- To evaluate the delivery efficiency of different SIB methods.
Main Methods:
- Four intensity-modulated radiation therapy (IMRT) techniques were analyzed in 12 patients.
- Techniques included tangential two-field (T-2F), tangential non-coplanar (T-NC), tangential VMAT (T-VMAT), and full VMAT (f-VMAT).
- Dosimetric parameters for targets and OARs, along with delivery efficiency (MUs, time), were compared.
Main Results:
- T-VMAT and f-VMAT demonstrated superior overall treatment quality.
- T-VMAT showed significantly lower doses to the ipsilateral lung and heart (at 5 Gy) compared to f-VMAT.
- f-VMAT achieved lower doses to the ipsilateral lung (at 20 Gy) and heart (at 30 Gy) in left-sided cases, with T-VMAT requiring fewer MUs.
Conclusions:
- The hybrid T-VMAT technique is recommended for breast SIB.
- T-VMAT provides an optimal balance between treatment quality, delivery efficiency, and OAR sparing.
- This technique represents a favorable choice for breast cancer radiotherapy planning.
