In the United States alone, about 3.3 million people are diagnosed with basal cell carcinoma and squamous cell carcinoma (skin cancer) annually. Skin cancer is still detected using limited reliable methods for visual inspection, early detection, subtyping, or measuring the degree of skin infiltration. Researchers at the Huntsman Cancer Institute (HCI) and the University of Utah (U of U) use a technique called non-visual electricity to take advantage of changes in the electrical properties of the skin that occur during the development of cancer cells. Created a device named URSKIN Impedance Population Statistics (EID).

EID measures the opposite of current, especially associated with skin cancer.

“URSKIN draws high-frequency, painless currents through the skin of interest,” said Dr. Benjamin Sanchez Terones, a member of the Cancer Center at HCI and an assistant professor of electrical and computer engineering at the University of Utah. .. Changes in cancerous skin tissue produce unique voltage signs that differ from clinically normal skin. “

Sanchez-Terrones and Doug Grossman, MD, Ph.D.He is a medical scientist at HCI and a professor of dermatology at the University of Utah. Pilot study The new device was tested in 18 patients who already had biopsy-confirmed basal cell carcinoma. Skin cancer..

“The clinical manifestations of basal cell carcinoma can be subtle,” says Grossman. “If there is a non-invasive device for early detection of basal cell carcinoma, and if a biopsy should be performed, and infiltration to guide the type of biopsy required for complete assessment. It is useful to be able to determine the depth. Tumor. “

Four different EID measurements were made on each patient to assess the electrical properties of basal cell carcinoma and the normal skin around it. URSKIN was able to detect a significant difference between basal cell carcinoma and the healthy skin next to it.The next step for the device is to investigate further Basal cell carcinoma Patients determine how well the device can distinguish subtypes and investigate their ability to identify other skin cancers, such as squamous cell carcinoma.

“Compared to visual inspection, URSKIN is low cost, easy to apply, quantitative and objective, and enables standardized electrical value measurements. skin“This new information gathered from the measurements helps doctors build confidence and overcome current diagnostic hurdles,” said Sanchez-Terrones.
