Castle Biosciences Showcases Advances in Melanoma Management
Castle Biosciences' Groundbreaking Research at ASCO 2025
Castle Biosciences, Inc. (Nasdaq: CSTL), a forward-thinking company dedicated to enhancing health through innovative testing solutions, is ready to share comprehensive research at the upcoming American Society of Clinical Oncology (ASCO) Annual Meeting. The event will spotlight the latest advancements in the treatment and management of cutaneous melanoma (CM) and uveal melanoma (UM), scheduled for May 30 to June 3, 2025, in Chicago. Their ongoing collaboration with the National Cancer Institute’s Surveillance, Epidemiology, and End Results (NCI's SEER) Program has unveiled significant data supporting the efficacy of the DecisionDx-Melanoma test, which has been applied to a vast cohort of over 13,500 patients.
Enhancing Clinical Management Through Precision Testing
Dr. Merve Hasanov, an oncologist and director of the medical oncology division at The Ohio State University Comprehensive Cancer Center, emphasizes the vital role of the DecisionDx-Melanoma test in refining patient management strategies. This test offers clinicians vital insights into the mortality risk associated with different melanoma stages, enabling more tailored treatment plans. Its ability to enhance predictions over traditional population-based assessments provided by the AJCC staging significantly elevates its clinical utility.
Studies Highlighted at ASCO
Castle’s presentations will feature key findings from two pivotal studies:
- The 31-gene expression profile can guide better risk-aligned care decisions for patients with stage I–III cutaneous melanoma
This NCI-SEER analysis represents the largest real-world study of gene expression testing, illustrating how the DecisionDx-Melanoma test accurately predicts mortality risk among AJCC sub-stages. The data demonstrate striking results, indicating that patients tested with DecisionDx-Melanoma experienced a remarkable 32% reduction in mortality risk compared to those who were not tested, reinforcing the test’s role in directing effective treatment strategies. - Independent validation of a 16-protein test to assess malignant potential of small uveal melanocytic tumors
Uveal melanoma, although rare, can become aggressive, with a concerning rate of metastasis. This study introduced a minimally invasive liquid biopsy method for identifying high-risk tumors using protein biomarkers, showcasing a promising alternative that could transform monitoring practices for patients with uveal melanocytic tumors.
Understanding DecisionDx-Melanoma and DecisionDx-UM
The DecisionDx-Melanoma test is a sophisticated 31-gene expression profile aimed at guiding comprehensive risk stratification for patients battling cutaneous melanoma. It integrates patient-specific tumor biology and clinical factors into a singular, actionable result that shapes personalized healthcare approaches. Evidence accumulated from over 50 peer-reviewed studies supports the significant association of this test with enhanced patient survival rates.
Similarly, DecisionDx-UM is a targeted 15-gene expression profile test that foresees metastasis risks in patients with uveal melanoma. It continues to be recognized as a vital component of clinical practice for uveal melanoma management, having established its significance in both AJCC guidelines and NCCN recommendations, underscoring its impact on treatment strategies.
