An analysis of a new, combined multi-center cohort of 1,412 high-risk SCC patients, with one or more NCCN High-Risk or Very-High-Risk factors, showed that DecisionDx-SCC significantly enhanced metastatic risk stratification in NCCN High- and Very-High-Risk patient populations (p &lt; 0.001). The test significantly improved BWH staging\u2019s risk prediction accuracy (p &lt; 0.001). Compared to the broader NCCN risk stratification, when DecisionDx-SCC was combined with BWH staging, Class 1 (low risk) test results showed a nearly two-fold decrease in metastatic risk and Class 2B (highest risk) results showed more than a five-fold increase in risk in lower-stage (BWH T1\/T2a) NCCN High-Risk patients. These findings show that DecisionDx-SCC can significantly refine risk assessment when used with established staging methods, enabling more accurate, personalized treatment decisions based on a patient\u2019s predicted metastatic risk.<\/p>\n<p>\n        <strong>DecisionDx-Melanoma<\/strong>\n      <\/p>\n<ul type=\"disc\">\n<li>Poster 31: <strong>The 31-GEP stratifies risk of death in patients with stage I-IIA cutaneous melanoma: A SEER real-world evidence study<\/strong><\/li>\n<li>Lead Author: Harrison Nguyen, M.D., MBA, MPH, Houston Skin, Houston<\/li>\n<\/ul>\n<p>\n        <strong>Study highlights: <\/strong>This poster, part of Castle\u2019s ongoing collaboration with the National Cancer Institute\u2019s Surveillance, Epidemiology and End Results (SEER) Program Registries, presents new validation of the DecisionDx-Melanoma test\u2019s risk-stratification performance in patients with thin\/early-stage CM tumors (stage I-IIA). In a large, unselected real-world cohort of 6,892 patients classified as low risk by the American Joint Committee on Cancer Eighth Edition (AJCC8) staging system, the test identified individuals at higher risk of death. In multivariable analysis that included key AJCC8 staging criteria such as tumor thickness and ulceration as well as age and mitotic rate, the data demonstrated that the DecisionDx-Melanoma test is a significant predictor of both melanoma-specific and overall mortality. These findings highlight the test\u2019s significant, independent risk-stratification capabilities, helping to identify patients at greater risk than indicated by AJCC8 staging alone who may benefit from enhanced surveillance and management to improve outcomes.<\/p>\n<p>All abstracts at the conference will be published online at <a href=\"https:\/\/www.globenewswire.com\/Tracker?data=9YQ7mBEa0pVC7SZxqDTR9Y1foHf9j3vBd3RZ6N0uWOmmE3vS8rmsGD-JRnpHr3nWEwsZQfMZLOiXUToaxdntgF7Y5FnKB6r5h8m-hzslBq9VD_pliTlrg0vTF0C69euBctzxjjkBrLxGkd0Mbc51lQ==\" rel=\"nofollow\" target=\"_blank\">JNCCN.org<\/a>.<\/p>\n<p>\n        <strong>About DecisionDx-SCC<\/strong><br \/>\n        <br \/>DecisionDx-SCC is a 40-gene expression profile test that uses an individual patient\u2019s tumor biology to predict individual risk of cutaneous squamous cell carcinoma metastasis for patients with one or more risk factors. The test result, in which patients are stratified into a Class 1 (low), Class 2A (higher) or Class 2B (highest) risk category, predicts individual metastatic risk to inform risk-appropriate management. Peer-reviewed publications have demonstrated that DecisionDx-SCC is an independent predictor of metastatic risk and that integrating DecisionDx-SCC with current prognostic methods can add positive predictive value to clinician decisions regarding staging and management.

It is designed to inform two clinical questions in the management of cutaneous melanoma: a patient\u2019s individual risk of sentinel lymph node (SLN) positivity and a patient&#8217;s personal risk of melanoma recurrence and\/or metastasis. By integrating tumor biology with clinical and pathologic factors using a validated proprietary algorithm, DecisionDx-Melanoma is designed to provide a comprehensive and clinically actionable result to guide risk-aligned patient care. DecisionDx-Melanoma has been shown to be associated with improved patient survival and has been studied in more than 10,000 patient samples. DecisionDx-Melanoma\u2019s clinical value is supported by more than 50 peer-reviewed and published studies, providing confidence in disease management plans that incorporate the test\u2019s results. Through Dec. 31, 2024, DecisionDx-Melanoma has been ordered more than 191,000 times for patients diagnosed with cutaneous melanoma.
