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.

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.

The importance of incorporating drug-drug interactions and lifestyle factors in pharmacogenomics-guided medication management for patients with major depressive disorder in a randomized controlled trial
Sep 2023
In this study, drug-drug interactions accounted for 32% of all IDgenetix-guided drug recommendations, and lifestyle factors accounted for 11%. Incorporating these non-genetic factors in IDgenetix testing significantly impacts the number of drug recommendations and improves remission rates in patients with moderate to severe depression.
