LA JOLLA, Calif.--(BUSINESS WIRE)--DermTech, Inc. (NASDAQ: DMTK) (DermTech), a leader in precision dermatology enabled by a non-invasive skin genomics platform, today announced that SKIN, the official journal of the National Society for Cutaneous Medicine, has published data showing that combining TERT DNA mutation analyses with DermTechs Pigmented Lesion Assay (the DermTech PLA) improved the test sensitivity for detecting melanoma to 97%, up from a sensitivity of 91% without TERT.

"Clinicians average 15-25 biopsies before a single melanoma diagnosis is made," said the lead author on the study, Stephanie Jackson Cullison, MD, PhD, Dermatology, University of Pittsburgh. "Biopsies cause discomfort and scarring for patients, and there is still a 17% chance of missing melanoma with this approach. Non-invasive analysis of gene expression and TERT mutations provides insight into the biological risk of a pigmented lesion without putting patients through potentially unnecessary procedures."

"This study points to the value of having additional genetic information and objective diagnostic tools to assess disease risk beyond what can be ascertained visually," said Laura K. Ferris, M.D., PhD, associate professor, Dermatology, University of Pittsburgh.

The study assessed 103 pigmented skin lesions clinically suspicious for melanoma with the objective of evaluating the expression of LINC, PRAME and select melanoma driver mutations. Samples from clinically concerning lesions, with one or more ABCDE criteria, represent both clinically-challenging borderline lesions as well as lesions at both ends of the severity spectrum. Lesions were first sampled using the DermTech PLA non-invasive adhesive patch test, and then each lesion was surgically biopsied immediately afterwards for standard histopathological diagnoses. The study shows that:

This study supports the addition of TERT to the PLA test to improve sensitivity of the test. TERT by itself has been shown by other investigators to provide a reasonable sensitivity and high specificity in differentiating benign from malignant lesions.1 The PLA plus TERT can serve as an important test to spare patients unnecessary biopsies and excisions all while enabling the detection of melanoma at the earliest stages, said John Dobak, M.D., Chief Executive Officer of DermTech.
