Summary
Accelerated Partial Breast Irradiation (APBI) provides a shorter, 5-day radiotherapy course after breast conserving surgery. This article details two multi-catheter interstitial APBI techniques: freehand and template-guided insertion.
Area of Science:
- Oncology
- Radiation Oncology
- Surgical Oncology
Background:
- Adjuvant radiotherapy is standard after breast conserving surgery.
- Accelerated Partial Breast Irradiation (APBI) offers a shorter treatment course (5 days) than conventional radiotherapy.
- Multi-catheter interstitial APBI provides excellent dosimetric coverage.
Purpose of the Study:
- To describe two insertion techniques for multi-catheter interstitial APBI.
- To discuss the indications, benefits, and drawbacks of each technique.
Main Methods:
- Description of the freehand technique for multi-catheter interstitial APBI insertion.
- Description of the template technique for multi-catheter interstitial APBI insertion.
Main Results:
- The freehand technique is operator-dependent.
- The template technique is easier to learn.
- Both techniques aim for excellent dosimetric coverage in APBI.
Conclusions:
- Multi-catheter interstitial APBI is a viable option for adjuvant radiotherapy.
- The choice between freehand and template techniques depends on operator experience and preference.
- Further evaluation of indications, benefits, and drawbacks is warranted.
