(Nasdaq: CSTL), a company improving health through innovative tests that guide patient care, today announced the publication of real-world clinical utility data in Cancer Investigation showing that clinicians are ordering DecisionDx®-SCC for the intended high-risk cutaneous squamous cell carcinoma (SCC) patient population and that use of the test’s results can lead to risk-aligned changes in patient management strategies.\n\n“The study highlighted the challenges of accurate risk assessments in the management of SCC when using clinicopathologic staging systems alone, and reinforced the need for a risk-stratification tool like DecisionDx-SCC that is designed to better identify patients with a higher likelihood of experiencing poor outcomes,” said Perry B. Hooper, M.D., Department of Dermatology, Indiana University School of Medicine, Indianapolis. “The personalized information provided by the test’s results can positively impact decision-making for SCC patients by helping better align treatment plans to a patient’s biologic metastatic risk and reducing the likelihood of over- or undertreatment.”\n\nThe paper, titled “Real-World Evidence Shows Clinicians Appropriately Use the Prognostic 40-GEP Test for High-Risk Cutaneous Squamous Cell Carcinoma (cSCC) Patients,” evaluated metrics from one year of clinical DecisionDx-SCC orders and the test’s impact on real-world risk assessments and treatment decisions. The paper may be viewed from Castle’s website.\n\nMetrics from real-world DecisionDx-SCC orders during the first year of testing show that physicians are ordering DecisionDx-SCC for patients with one or more high-risk clinicopathologic factors:\n\n\nOf the 2,503 samples tested between Aug. 31, 2020-Aug. 31, 2021, 98.1% were successfully tested and received the following results: 68.8% received a low-risk (Class 1) result, 28.3% received a moderate-risk (Class 2A) result and 2.9% received a high-risk (Class 2B) result.\n\n\n75% of samples had two or more high-risk clinicopathologic factors, and 98.8% of cases submitted for testing were classified as high r...
