|Keloid Scar||Radiation: SRT-100|
A keloid is an unsightly non-malignant tumor comprised of an abnormal proliferation of scar tissue that forms at the site of cutaneous injury (e.g. skin trauma such as cuts, abrasions and puncture wounds, burns or surgical incisions). It appears as a raised scar and does not regress and grows beyond the original margins of the scar. Keloids most commonly develop on the earlobes, neck, shoulders, chest, back, upper arms and cheeks. Keloids tends to grow slowly and continue to spread for weeks, months or even years. As a keloid grows, it may cause significant itching, pain, and tenderness upon touch, reduced mobility and emotional distress.
About 18 million people worldwide are genetically prone to form keloids in response to skin trauma, with equal gender distribution and greater susceptibility for darker-skinned individuals and those aged 10 to 30 years.
The greatest obstacle in treating keloids with many available surgical and non-surgical methods is that new keloids typically recur at the site of excision due to the treatment itself. For example, the recurrence rate using surgical excision alone is 45 to 100 percent.
Surgical excision followed by radiotherapy is a helpful treatment option for large and more difficult-to-treat keloids that cannot otherwise be treated by, or have failed, more conservative measures. It is thought that because keloid fibroblasts are sensitive to x-ray irradiation, it may prevent the recurrence of keloids by controlling fibroblast proliferation, arresting the cell cycle, and inducing premature cellular senescence. When surgical keloid excision is followed by Radiation Therapy, recurrence drops dramatically to 10% or below.
The SRT-100™ is a United States Food and Drug Administration (U.S. FDA) approved device for delivering a precise, calibrated dose of Superficial Radiation Therapy (SRT) to treat keloids caused by surgery or injury. This retrospective study has been designed to focus on efficacy and safety of the SRT-100™ for the treatment of recurrent keloid scars.

- Radiation: SRT-100
The SRT-100™ is a simple painless non-invasive in-office procedure that is approved by the U.S. Food and Drug Administration (U.S. FDA) to treat keloids caused by surgery or injury by delivering a precise, calibrated dose of Superficial Radiation Therapy (SRT) that only goes skin deep.
- Long-term recurrence rate [ Time Frame: one year ]Recurrence rate will be calculated as the percentage of keloids that recurred at the treatment site following treatment completion.
