Image-Guided Superficial Radiation Therapy (IG SRT)
Skin cancer is the most common type of skin cancer diagnosed in the United States and can affect anyone of any age. The most common forms of non-melanoma skin cancers include basal cell and squamous cell carcinomas. While the standard treatment for removal of these forms of cancer is surgical excision, there is now another non-surgical option available with high cure rates: Image-Guided Superficial Radiation Therapy (IG-SRT).
Image-Guided Superficial Radiation Therapy (IG-SRT) is a low-dose radiation treatment that effectively eliminates non-melanoma skin cancer and keloids. While traditional skin cancer procedures are effective, they require surgical incisions and a lengthy recovery. IG-SRT requires no anesthesia, incisions, stitching, scarring, pain, or downtime.
This treatment differs from traditional SRT, which employs radiotherapy without the benefit of ultrasound images. The ultrasound images let your dermatologist see the exact size of the cancer so he or she can target the area with the accurate dose. These images also show the cancer shrinking after each treatment.
IG-SRT is an FDA-cleared non-surgical treatment option for basal cell carcinoma, and squamous cell carcinoma. According to the National Comprehensive Cancer Network guidelines, radiation therapy such as IG-SRT is an effective treatment option for patients.
This treatment utilizes a small, portable device that delivers low energy just beneath the skin’s surface. Using a precise, calibrated dose of SRT that only penetrates up to five millimeters under the skin’s surface, this minimally invasive treatment effectively removes both basal and squamous cell carcinoma, as well as unwanted keloids.
The machine used, the SRT-100 Vision, allows providers to see and treat the affected areas through high-frequency ultrasound for imaging. This allows for the treatment areas to be more thoroughly assessed, for more precise results. Treatments generally take about 10-15 minutes total per appointment.
Ideal candidates for IG-SRT are those with basal cell or squamous cell carcinomas (non-melanoma skin cancer). Individuals who are afraid of needles or surgery, or those who are unfit for surgery due to health issues or conditions may also be good candidates. Skin cancers that are difficult to treat with surgery such as cancers on the scalp, ears, eyes, hands, feet and shins are often great candidates for IG-SRT.

Following IG-SRT, there are no downtime or lifestyle restrictions, so patients can return to their regular activities, including work, as soon as they wish. It requires a short appointment 3-4 times per week for 5-6 weeks to complete therapy

IG - SRT Timeline
A biopsy will be performed on the questionable lesion in the clinic.
Once your biopsy results are available, we will contact you. If skin cancer is present, it will typically require a follow up treatment. Some of the most common treatment options are standard excision, Mohs surgery, IG-SRT, or an electrodesiccation and curettage procedure.
Verification Of Benefits (VOB)
While you are considering your treatment options, we will perform a VOB to determine the likely cost of the procedures based on your health insurance.
When the VOB is completed, we will contact you with the estimated cost of the procedure, as well as arrange for any payment plans. If you decide to undergo IG-SRT, we will schedule your simulation.
During a Simulation (Sim) appointment, the exact area to be treated will be outlined or mapped. You will be asked to sign consent forms and go over all expectations. Setup photos, ultrasound images, and treatment parameters will be discussed with your provider to determine your plan.
At each treatment appointment, we will assess for poor skin reactions, determine your progress with ultrasound, and provide treatment. Every 5 treatments, your provider will review your case to ensure that treatment is going well.
Following your last treatment, you will follow up in six weeks for re-evaluation. We will repeat an ultrasound to ensure that all skin cancer is eliminated. In some cases, a booster may be needed.
Potential Boosts are added treatment doses that are administered over a few appointments.
