In this case, a more accurate assessment of the state of disease was attained through 40-GEP testing. Traditional staging methods, including AJCC8 and BWH, overestimated our patient’s risk profile. More research needs to be completed surrounding gene testing and metastatic risk. Our goal with this case is to contribute to the growing body of literature surrounding the use of gene expression profile testing in cutaneous cancer.

Incorporating a prognostic gene expression profile test into the mangement of cutaneous squamous cell carcinoma: An expert consensus panel report
Dec 2023
The 40-GEP test provides accurate and independent prognostic information beyond standard staging systems that only incorporate pathologic data. In this consensus paper, 8 dermatologists with significant expertise in diagnosing and managing cSCC concluded that incorporation of GEP testing into national guidelines can help further stratify patients based on risk of metastasis, and thus may improve morbidity and mortality.

An Automated Tissue Systems Pathology Test Can Standardize the Management and Improve Health Outcomes for Patients with Barrett's Esophagus
Nov 2023
Management guided by the TissueCypher test can standardize care plans by increasing the early detection of progressors who can receive therapeutic interventions, while also increasing the percentage of nonprogressors who can avoid unnecessary therapy and be managed by surveillance alone.
