[{"type":"text","content":" FRIENDSWOOD, Texas--(BUSINESS WIRE)--\nCastle Biosciences, Inc. (Nasdaq: CSTL), a company improving health through innovative tests that guide patient care, today announced new data showing that DecisionDx-SCC can independently risk-stratify patients with cutaneous squamous cell carcinoma (SCC) and one or more risk factors according to their biologic risk of metastasis, consistent with findings in previous development and validation studies.1,2 The poster was presented at the 2022 American College of Mohs Surgery (ACMS) Annual Meeting.\n\nDecisionDx-SCC is Castle’s prognostic 40-gene expression profile (GEP) test designed to use a patient’s tumor biology to predict individual risk of metastasis for patients diagnosed with SCC who have one or more high-risk factors. The test stratifies patients into one of three classes based on their biologic risk of metastasis: Class 1 (low risk), Class 2A (moderate risk) or Class 2B (high risk).\n\n“Identifying which patients are at an increased risk of disease progression and metastasis is a challenge for clinicians who may see hundreds of cutaneous squamous cell carcinoma cases in their practices each year,” said study author Sarah T. Arron, M.D., Ph.D., Mohs surgeon and dermatologist at Peninsula Dermatology in Burlingame, California. “Using DecisionDx-SCC to add a patient’s biologic risk to our existing clinical and pathologic risk-assessment methods can improve our decision-making and help us to personalize treatment for our patients.\"\n\nThe poster, titled “Performance of the prognostic 40-gene expression profile (40-GEP) test for high-risk cutaneous squamous cell carcinoma (cSCC) in a second independent cohort,” highlights data from a second, independent, multi-center study of high-risk SCC patients, consisting of 598 novel patient samples from 43 contributing centers. The poster can be viewed here. With the cohort of patients in this study, combined with the cohort of patients from the first validation study (n=420), the ability of DecisionDx-SCC to independently stratify risk has been confirmed in a total of 1,018 patients.\n\nKaplan-Meier analysis showed a statistically significant difference in metastasis-free survival (MFS) rates between DecisionDx-SCC Class 1, Class 2A and Class 2B results (p","length":2821,"tagName":"div"}]
