Prognostic gene expression profile test for metastatic risk in cutaneous squamous cell carcinoma now available to clinicians in the U.S.
Conference Call and webcast today at 4:30 p.m. ET
FRIENDSWOOD, Texas–(BUSINESS WIRE)–Sep. 2, 2020– Castle Biosciences, Inc. (Nasdaq: CSTL), a skin cancer diagnostics company providing personalized genomic information to improve cancer treatment decisions, today announced that DecisionDx®-SCC, its prognostic gene expression profile test for patients diagnosed with high-risk cutaneous squamous cell carcinoma (SCC), is now commercially available.
“We are pleased to offer DecisionDx-SCC, intended for use in adding actionable, patient-specific information to risk assessment and to help guide management decisions in SCC,” said Derek Maetzold, president and chief executive officer of Castle. “Using current SCC staging methods, about 200,000 patients annually are classified as high risk based on various clinical and pathological factors. But this relatively broad high-risk category leaves room for over- and undertreatment—a degree of uncertainty that patients and clinicians cannot afford, as death rates from SCC continue to rise. Now with the ability to add DecisionDx-SCC to commonly used clinical and pathological factors, we believe that this important innovation will improve prognostic accuracy and risk-appropriate management planning. We expect to see strong demand for DecisionDx-SCC, as we build upon our success with DecisionDx-UM and DecisionDx-Melanoma and follow our established model for commercialization.”
Ashley Wysong, M.D., University of Nebraska Medical Center, Omaha NE stated, “As SCC cancer treatment plans and their outcomes are guided by risk of metastasis, improved prognostic accuracy has direct implications on patient management. By classifying SCC patients with existing risk factors into low, moderate and high biological risk categories, we believe DecisionDx-SCC can contribute positive predictive value to follow-up and management recommendations, potentially changing or narrowing recommendations in line with individual risk. I look forward to integrating tumor biology through DecisionDx-SCC into the clinical care of my patients.”
The DecisionDx-SCC test is a qRT-PCR assay of 40 genes that uses a neural network algorithm to classify patients into risk categories. Independent validation was performed in a prospectively designed, multi-center (33 sites) study using archival tissue from 420 patients with known 3-year outcomes. The test’s validity and impact are supported by four peer-reviewed publications.

About Squamous Cell Carcinoma
Cutaneous squamous cell carcinoma (SCC) is one of the most common cancers. Approximately 1 million patients are diagnosed with SCC each year in the U.S. While the majority of these patients have a favorable prognosis, approximately 200,000 of these patients are identified as high risk. National guidelines for high-risk patients provide for broad, aggressive treatment plan recommendations relative to low-risk patients. Traditional clinicopathologic based risk-factor staging systems suffer from low positive predictive value, meaning many more patients are classified as high risk than actually develop metastatic disease. This may lead to over- and under-treatment of a substantial number of cutaneous SCC patients.
DecisionDx-SCC is a 40-gene expression profile test that uses an individual patient’s tumor biology to predict individual risk of squamous cell carcinoma metastasis for patients with one or more risk factors. The test result, in which patients are stratified into a Class 1, 2A or 2B 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.
