PHOENIX — More specifically, the persistent growth in the use of superficial radiotherapy (SRT) devices and electronic brachytherapy (eBT) to treat nonmelanoma skin cancer (NMSC) has exceeded that of traditional procedures among dermatologists using these modalities, according to Christian Gronbeck, MD, a resident in dermatology at the University of Connecticut Health Center, Farmington.
“These services increased substantially over the study period,” Dr. Gronbeck said at the annual meeting of the American College of Mohs Surgery, where he presented the results of the study. “Our findings suggest that those using eBT/SRT were frequently general dermatologists and non-fellowship–trained Mohs surgeons who have less formalized surgical training.”
He also noted that billing for these services also rose substantially, which is being driven by growing utilization and an increased SRT payment rate.
Surgical approaches are standard for most NMSC cases, but some patients are not good surgical candidates because of medical comorbidities and/or other factors, and radiotherapy is emerging as a potential treatment option for those patients. Traditionally, radiotherapy was administered by radiation oncologists, but with the growing availability of SRT devices and the introduction of eBT, dermatologists are now treating patients with these modalities.
“It is a potential treatment option for nonmelanoma skin cancer and keloids, and these lower energy devices can be used in the outpatient setting,” said Dr. Gronbeck. “Treatment typically involves a series of fractions over a period of several weeks. There has been recent growth in the use of radiotherapy despite this being a secondary option in skin cancer, primarily when surgery is contraindicated.”
Steady Expansion of Use
Dr. Gronbeck and colleagues sought to gain a better understanding of the use of SRT and eBT for NMSC among dermatologists, as well as trends in cost. Data were obtained from the 2016-2021 Medicare Public Use Files to evaluate the trend in the volume of Medicare Part B claims for eBT (CPT 0394T) and SRT (CPT 77401) by dermatologists, and they also looked at related billable services for radiotherapy.
Of 12,050 dermatologists, 293 (2.4%) were identified as utilizing eBT or SRT in 2021, representing a 75.4% increase from 2016. The usage of both eBT and SRT increased by 59.6% and 148.4%, respectively, from 2016 to 2021.
There were notable geographic differences in the utilization of radiotherapy. “Florida, California, Texas, and Arizona had the highest utilization,” Dr. Gronbeck said, although during the study period, utilization increased in other states, including North Carolina and Alabama.
When looking at geographic regions as a whole, the highest number of dermatologists using radiotherapy were located in the South (n = 143, 50.9%), followed by the West (n = 69, 23.6%). Utilization was more common in metro areas than in nonmetro/rural areas (86% vs 14%).
Differences were also noted among dermatologists. Those who performed eBT/SRT than those who did not were significantly more likely to have had 15 or more years of independent practice (70.1% vs 48.6%), be in a small private dermatology practice (62.7% vs 47.5%), and be non–fellowship-trained Mohs surgeons (33.5% vs 10.2%). Dermatologists utilizing radiotherapy were also more likely to treat Medicare beneficiaries who were older, with a mean age over 75 years (39.3% vs 31.1%) and a mean hierarchical condition category (HCC) score, above the national average (55.2% vs 44.6%).
Dr. Gronbeck and colleagues also looked at cost. The number of direct payments for eBT/SRT payments increased throughout the study period, from 3,678,224 in 2016 to 11,680,925 in 2021, nearly a 218% increase. The change in payments for services related to eBT/SRT, such as radiotherapy simulation, radiotherapy dosing, and ultrasound guidance, increased by 621.4% during this same timeframe.
Radiotherapy in dermatology has primarily been assessed through retrospective studies. “Our findings suggest that eBT and SRT are more frequently utilized by dermatologists managing older and sicker patients, but further studies are needed to identify whether these interventions are truly addressing poor surgical candidates,” Dr. Gronbeck said.
The Centers for Medicare & Medicaid Services (CMS) has recently proposed changes in Medicare coverage in seven states for Image-Guided Superficial Radiation Therapy (image-guided SRT or IGSRT) for the treatment of NMSC. The proposed local coverage determination, or LCD, if finalized in its current form, would affect residents in North Carolina, South Carolina, Virginia, West Virginia, Alabama, Georgia, and Tennessee.
“These changes would mean more restrictive coverage,” said Dr. Gronbeck, and further support the need for “improved clinical data and development of guidelines to support evidence-based utilization.”
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.
