Summary
Radiotherapy (RT) significantly improves breast cancer survival and reduces mortality when used after mastectomy or lumpectomy. This review covers the use of RT in breast cancer management and partial-breast irradiation techniques.
Area of Science:
- Oncology
- Radiation Oncology
Background:
- Radiotherapy (RT) has been a cornerstone in breast cancer management for over 50 years.
- While its benefit in local control is well-established, recent evidence highlights its impact on overall survival and mortality.
- Adjuvant RT plays a crucial role in reducing breast cancer recurrence and improving patient outcomes.
Purpose of the Study:
- To summarize the established role of adjuvant radiotherapy in breast cancer treatment following mastectomy and lumpectomy.
- To review the scientific rationale and technical aspects of partial-breast irradiation (PBI).
- To provide an overview of modern radiotherapy applications in breast cancer care.
Main Methods:
- Literature review of studies on adjuvant radiotherapy in breast cancer.
- Analysis of data regarding the impact of RT on local control, survival, and mortality.
- Description of techniques and indications for partial-breast irradiation.
Main Results:
- Adjuvant radiotherapy significantly improves both local control and overall survival in breast cancer patients.
- RT after mastectomy and lumpectomy is associated with reduced breast cancer mortality.
- Partial-breast irradiation offers a targeted approach with potential benefits for select patient populations.
Conclusions:
- Adjuvant radiotherapy is essential for improving survival outcomes in breast cancer.
- Partial-breast irradiation is an evolving technique with a defined role in specific breast cancer cases.
- Continued research and refinement of RT techniques are vital for optimizing breast cancer treatment.
