Surgical Management Standard, but SRT Has a Role
Asked to comment on the findings, Seemal R. Desai, MD, president of the American Academy of Dermatology (AAD), who was not involved with the study, reiterated that according to this abstract, efficacy has mainly been assessed through retrospective studies, and results are likely inferior to Mohs surgery, require multiple treatment visits, and are associated with significant costs. More study is needed for the use of radiation therapy in dermatology, he told this news organization.

“The Academy supports continued research and studies for therapies that can help improve patient outcomes and offer treatment options, as well as further studies on long-term outcomes for treatments like superficial radiation therapy,” he said.
“Well-designed studies can certainly be helpful to better assess efficacy and outcomes,” Dr. Desai continued. “This is why the Academy supports the idea of scientific studies that continue to expand the body of literature and data, which can help dermatologists tailor therapeutic options for their patients.”
As for general dermatologists using radiation therapy, he pointed out that SRT was developed within the dermatology specialty with dermatologists being the experts in delivering SRT for patients with NMSCs when indicated. “SRT has been used for over 100 years to treat skin cancer,” said Dr. Desai, of the department of dermatology, UT Southwestern Medical Center, Dallas. “While certain radiation devices have historically been used by dermatologists, dermatologists engaged in providing superficial radiation therapy must have adequate education and training to administer this therapy safely and effectively.”
The AAD Association (AADA) has a position statement that supports the use of SRT as an option for the treatment of basal cell carcinoma and squamous cell carcinoma in certain circumstances. “This could be when surgical intervention is contraindicated or refused and after the benefits and risk of treatment alternatives have been discussed with the patient,” he said. “Based on current evidence, surgical management remains the most effective treatment for NMSC.”
Dr. Desai added that the AADA is also concerned that if the Proposed LCD is finalized by CMS, it “could restrict dermatologists from performing SRT and impede patient access to SRT as a potential treatment when indicated.”
The study was independently supported. Dr. Gronbeck and Dr. Desai reported no relevant financial relationships.
