Summary
Breast irradiation after breast-conserving surgery is crucial for improving survival. This review covers its indications, techniques, and complications, alongside new methods like tangential irradiation.
Area of Science:
- Oncology
- Radiotherapy
- Surgical Oncology
Background:
- Breast-conserving surgery (BCS) is a standard treatment for breast cancer.
- The role and optimal techniques of adjuvant breast irradiation following BCS require ongoing evaluation.
- Systemic therapies are increasingly integrated with local treatments.
Purpose of the Study:
- To critically review the significance of breast irradiation after BCS.
- To discuss indications, complications, and timing of breast irradiation.
- To present novel irradiation techniques and future directions.
Main Methods:
- Comprehensive literature review of breast irradiation following BCS.
- Analysis of indications, complications, boost irradiation, and survival benefits.
- Inclusion of institutional data and novel technical advancements.
Main Results:
- Breast irradiation significantly improves survival outcomes.
- Boost irradiation and systemic therapy enhance efficacy.
- New techniques like tangential axillary irradiation and 3D simulation offer improved planning and delivery.
Conclusions:
- Breast irradiation is a vital component of BCS, improving local control and survival.
- Careful patient selection and advanced techniques optimize treatment benefits.
- Further research into hypofractionated radiotherapy and omission in low-risk patients is warranted.
