"The authors evaluated peer-reviewed articles that analyzed DecisionDx-Melanoma risk class data alongside at least one survival-based metric with a minimum of three years of follow-up...Across all studies, the DecisionDx-Melanoma test consistently stratified patients into risk groups with significantly different outcomes. The five-year melanoma-specific survival rates were: 99.8% (95% CI: 98–100%) for patients with a Class 1A/lowest risk test result, 97.6% (95% CI: 92.4–99.3%) for patients with a Class 1B/2A/increased risk test result and 83.4% (95% CI: 66.5–92.7%) for patients with a Class 2B/highest risk test result. Similar trends were observed for recurrence-free and distant metastasis-free survival, showing a significant separation of risk between patients with Class 1A and Class 2B test results."

P=NA | N=NA | "The study showed that integrating DecisionDx-Melanoma test results into SLNB decisions resulted in 25% fewer SLNBs performed compared to a matched patient cohort (p<0.001). Further, no patients with a DecisionDx-Melanoma-predicted risk of SLN positivity of less than 5% who decided to have an SLNB had a positive SLN (0/58 patients). Further, 9.8% of patients with a DecisionDx-Melanoma-predicted risk of SLN positivity of 5% or more who had the procedure did have a positive SLN."

"Castle Biosciences, Inc...today announced the publication of two recent studies that provide further support for the clinical need of its MyPath® Melanoma gene expression profile (GEP) test, designed to aid in providing an accurate diagnosis for ambiguous melanocytic lesions of uncertain malignant potential."

P=NA | N=876 | "The data show DecisionDx-Melanoma stratified patients by their risk of recurrence and was a significant predictor of recurrence; patients with Class 1A (lowest risk) test results had significantly higher three-year recurrence-free survival than those with a Class 1B/2A (increased risk) or Class 2B (highest risk) test result (p<0.001). Importantly, the test added significant predictive value to American Joint Committee on Cancer (AJCC) staging, considered the standard of care in melanoma management. These findings provide evidence that use of the test with melanoma patients enables better risk-aligned care decisions, which have been shown to lead to improved patient outcomes."

"Castle Biosciences, Inc...today announced that it will present new data related to its DecisionDx-Melanoma and DecisionDx® -UM tests for patients with cutaneous melanoma (CM) and uveal melanoma (UM), respectively, at the 21st International Congress of the Society for Melanoma Research (SMR), taking place Oct. 10-13, 2024, in New Orleans."

P=NA | N=954 | "The data will be shared in an oral presentation at the American Society for Radiation Oncology (ASTRO) 2024 Annual Meeting....Patients with T1 tumors had similar metastasis-free survival (MFS) rates regardless of immune status yet were further stratified by their DecisionDx-SCC test result (3-year MFS: Class 1 test result: 96.9% vs. Class 2A/2B test result: 88.6%, p<0.001). Immune suppressed patients with T2a tumors had significantly worse MFS than immune competent patients with T2a tumors (71.4% vs. 91.2%, p<0.001). DecisionDx-SCC further stratified immune suppressed patients with T2a tumors into those with more favorable (Class 1 test result; 3-yr MFS of 83%) and less favorable survival (Class 2A/2B test result; 3-yr MFS of 57%)."

"Castle Biosciences, Inc...announced the publication of a new study further demonstrating that DecisionDx-Melanoma can precisely predict sentinel lymph node (SLN) positivity risk to help guide risk-aligned SLNB decisions, potentially reducing the number of unnecessary procedures and increasing the SLNB positivity yield if the procedure is performed."

P=NA | N=399 | "Castle Biosciences, Inc...today announced the publication of a new study in Future Oncology further substantiating use of its DecisionDx-SCC test in guiding patient selection and decision-making related to the use of ART in patients with high-risk SCC based on the ability of the test to identify patients likely to benefit from treatment...'In this study, we were successful in validating, in an independent SCC patient cohort, that DecisionDx-SCC can objectively inform these challenging decisions by identifying patients for whom ART would be beneficial, as well as those who may be best served by avoiding it. In the study, a novel, independent cohort of patients with high-risk SCC tumors (399 patients; 423 tumors) from two academic centers were tested using DecisionDx-SCC and analyzed for five-year metastasis-free survival and projected time to metastasis."

"Castle Biosciences, Inc...today announced that its executive management is scheduled to present a company overview at the Canaccord Genuity 44 th Annual Growth Conference on Tuesday, Aug. 13, 2024, at 12:30 p.m. Eastern time."

"Castle Biosciences...announced that it will present new data related to its DecisionDx-Melanoma and DecisionDx-UM tests at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting, being held May 31-June 4, 2024, in Chicago."

P=NA | N=920 | "Castle Biosciences...announced the publication of a study in the International Journal...demonstrating the ability of the DecisionDx-SCC test to identify high-risk cutaneous squamous cell carcinoma (SCC) patients at the highest risk of metastasis who will benefit the most from ART to reduce metastatic disease progression, as well as high-risk patients who the test identified as having a lower risk of metastasis who may consider deferring treatment....Key findings of the study (n=920 patients) include: The DecisionDx-SCC test identified patients projected to receive the greatest benefit from ART to reduce metastatic disease progression. Patients with a Class 2B (highest metastatic risk) test result who were treated with ART had 50% higher MFS rates, on average, than Class 2B patients who did not receive ART at five years post-diagnosis."

P=NA | N=1,586 | "Castle Biosciences...announced new data from a study further confirming the performance of its DecisionDx-UM test as a robust independent predictor of metastasis-free survival (MFS) in patients diagnosed with UM....The data was presented at the Association for Research in Vision and Ophthalmology (ARVO) 2024 Annual Meeting....In the study, a DecisionDx-UM Class 2 result was the most robust independent predictor of MFS (HR 6.03; 95% CI, 4.49-8.09); P<0.001), followed by PRAME status (HR 1.77; 95% CI, 1.39-2.27; P<0.001). Patients with Class 2 tumors had considerably worse outcomes than those with Class 1 tumors, regardless of PRAME status; however, PRAME+ tumors fared worse within each GEP class (versus PRAME-). When considered together, five-year MFS rates were 95.6% (95% CI, 93.9-97.4) for Class 1/PRAME-, 80.6% (73.9-87.9) for Class 1/PRAME+, 57.6% (50.6-65.7) for Class 2/PRAME- and 44.8% (38.0-52.8) for Class 2/PRAME+."

P=NA | N=417 | "Castle Biosciences, Inc...announced that new data supporting the utility of its DecisionDx-SCC test in patients with high-risk cutaneous squamous cell carcinoma (SCC) tumors located on the head and neck (H&N) will be shared at the 56th American College of Mohs Surgery (ACMS) Annual Meeting, being held May 2-5 in Phoenix....DecisionDx-SCC testing of the tumor tissue before removal significantly increased the prediction accuracy of metastatic events, when used alone and when combined with National Comprehensive Cancer Network (NCCN) guidelines, Brigham and Women’s Hospital (BWH) staging or American Joint Committee on Cancer Staging Manual, 8th Edition (AJCC8) staging, to better guide risk-aligned patient care decisions regarding metastatic surveillance or the use of adjuvant treatments like radiation."

P=NA | N=760 | "Castle Biosciences...will share new data at the 20th European Association of Dermato-Oncology (EADO) Congress, being held April 4-6, 2024....Abstract: A-128:...This study evaluated the performance of a risk-stratification nomogram developed in Europe (Rentroia-Pacheco, et al, 2023) in a U.S. cohort of high-risk SCC patients (n=760) and the additional prognostic value provided by the DecisionDx-SCC test. In the study, the nomogram misclassified nine out of 10 tumors that metastasized as low risk. When the same tumors were tested using DecisionDx-SCC, 42% of those that the nomogram classified as low risk of metastasis were classified as high risk by the test, as well as 70% of all tumors that metastasized. These data demonstrate that DecisionDx-SCC improves the accuracy of risk assessment based solely on clinicopathological risk factors, leading to more appropriate risk-aligned management plans for patients with high-risk SCC."
