“11 Days Until Brachytherapy Awareness Day 2026.
Interventional Radiotherapy (Brachytherapy) for Postoperative Keloid Scars.
A successful surgery does not always mark the end of treatment. For patients prone to keloid formation, postoperative management is essential to reduce the risk of recurrence and achieve the best cosmetic outcome.
Interventional Radiotherapy (Brachytherapy) has become an effective adjuvant treatment for selected patients following surgical excision of keloids. By placing flexible interstitial catheters directly within the surgical scar, brachytherapy delivers a high radiation dose precisely to the tissue at greatest risk of recurrence while minimizing exposure to surrounding healthy skin.
The unique physical properties of brachytherapy make it particularly well suited for treating superficial lesions and surgical scars.
Why postoperative brachytherapy?
- Significantly reduces the risk of keloid recurrence
- Delivers a highly conformal radiation dose to the entire surgical scar
- Rapid dose fall-off protects surrounding healthy tissues
- Excellent cosmetic outcomes
- Short treatment duration
According to the German S2 Guideline, postoperative high-dose-rate (HDR) brachytherapy should ideally begin within 24 hours after surgical excision.
Typical treatment schedules include:
- 3-4 Gy per fraction
- Total dose: 10–20 Gy
- Treatment individualized according to scar size, anatomical location, and recurrence risk
Interventional Radiotherapy is more than a cancer treatment it is also an important therapeutic option for selected benign conditions where treatment precision is critical.
Treat the scar. Prevent recurrence. Preserve quality of life.
