(Nasdaq: CSTL) develops and commercializes molecular diagnostic tests that guide patient care for dermatologic cancers, Barrett's esophagus, uveal melanoma, and related conditions; its core portfolio includes DecisionDx-Melanoma, a 31-gene expression profile (GEP) test predicting metastasis risk, sentinel lymph node positivity, and recurrence in invasive cutaneous melanoma; TissueCypher, a spatial-omics risk stratification test predicting progression to high-grade dysplasia or esophageal cancer in Barrett's esophagus patients with non-dysplastic, indefinite, or low-grade dysplasia; DecisionDx-SCC, a 40-GEP test assessing metastasis risk, adjuvant radiation therapy benefit, and local recurrence in high-risk cutaneous squamous cell carcinoma; MyPath Melanoma, a diagnostic GEP test aiding differentiation of melanocytic lesions; DecisionDx-UM, a GEP test with PRAME refinement predicting metastasis in uveal melanoma; and AdvanceAD-Tx, a 487-GEP test guiding systemic treatment selection for moderate-to-severe atopic dermatitis patients aged 12 and older. The company, founded in 2008 and headquartered in Friendswood, Texas, operates laboratories in Phoenix, Arizona, and Pittsburgh, Pennsylvania, serving clinicians in dermatology, gastroenterology, and oncology primarily in the United States.
