A new study1 has found that DermaSensor Inc.'s skin cancer detection device helps improve the disease's diagnosis and reduces the chances of physicians missing it.
The study in the Journal of Primary Care and Community Health, authored by medical leaders including Laura Korb Ferris, M.D., and Todd Thames, M.D., evaluated the impact of DermaSensor's device on physicians’ skin cancer diagnosis and management. The study involved 57 U.S. board-certified doctors who collectively completed more than 5,000 assessments of skin lesions.1
This recently published utility study follows a recently published preceding clinical study, which was conducted to determine the standalone performance of the device and was recently published by the American Academy of Dermatology.2 The device, which employs elastic scattering spectroscopy (ESS) and machine learning, was found in this utility study to significantly improve physicians’ referral of malignant lesions to dermatologists. This companion study was conducted to provide clinical evidence for European regulatory authorities as well as initial effectiveness evidence for the U.S. Food and Drug Administration (FDA), which approved the company's skin care evaluation system in mid-January.
Skin cancer remains the most prevalent type of cancer in the United States, posing a significant challenge for PCPs who often encounter patients with suspicious skin lesions. DermaSensor’s innovative handheld device, developed as an objective tool for the primary care setting, aims to address this challenge by providing immediate information on lesions’ risk level through its optical spectroscopy and machine learning technology.
The study's key findings were that physicians’ skin cancer referrals increased from 81% to 94% (p-value = 0.0009), thereby decreasing missed skin cancers by 68% (from 19% to 6%). The specificity also decreased from 36% to 31%, which was a non-significant decrease (p-value = 0.3558). Similarly, the physicians’ diagnostic sensitivity significantly increased and their diagnostic specificity non-significantly decreased. The device was also found to significantly improve doctors’ confidence in their clinical decisions.
Laura Korb Ferris, M.D., senior author of this paper and professor of Dermatology and Director of the University of Pittsburgh Department of Dermatology Clinical Trials Unit, was optimistic about the study findings: “Our study indicates that DermaSensor’s ESS device has the potential to enhance the detection of skin malignancies in the primary care setting. This technology not only improved PCPs’ sensitivity for lesion referral but also significantly increased their confidence, both of which are particularly important for non-specialists”.
“The findings of this study reinforce our commitment to providing innovative solutions for the detection of skin cancer. The findings from this study suggest that the device could greatly benefit PCPs and their patients. It is an honor that this journal and group of authors have published these study findings, including Dr. Ferris, who is a world-renowned thought leader in the field of non-invasive skin cancer detection tools,” DermaSensor CEO Cody Simmons stated.
The ESS device utilizes advanced spectroscopy and machine learning to evaluate lesions risk of being malignant, providing physicians with valuable information that will augment their clinical assessment and management decisions. The device’s AI algorithm was trained with more than 10,000 spectral recordings from a diverse set of skin lesions.2
