Castle Biosciences Presents Second Study Confirming Ability of DecisionDx-Melanoma to Inform Sentinel Lymph Node Biopsy Decisions at the 8th International Congress on Cancer Metastasis

Castle Biosciences, Inc. (Nasdaq: CSTL), a skin cancer diagnostics company providing personalized genomic information to improve cancer treatment decisions, today announced the presentation of data supporting clinical use of the DecisionDx®-Melanoma test to inform decisions of whether to discuss or recommend the sentinel lymph node biopsy (SLNB), a surgical procedure used to provide additional prognostic information. The study found that DecisionDx-Melanoma test results can be used with clinicopathologic factors to identify patients at low risk of sentinel lymph node (SLN) positivity. This information can inform patient discussions and recommendations regarding the SLNB surgical procedure in line with national melanoma clinical practice guidelines.

The study titled, “Identification of T1-T2 melanoma patients at low risk for a positive sentinel lymph node using the 31-gene expression profile test,” was presented during an Oral Abstract session at the 8thInternational Congress on Cancer Metastasis (ICCM) in San Francisco, October 25-27.
