Integrating the 40-gene expression profile (40-GEP) test improves metastatic risk-stratification within clinically relevant subgroups of high-risk cutaneous squamous cell carcinoma (cSCC) patients
Mar 2024
The 40-GEP test demonstrates accurate, independent, clinically actionable stratification of metastatic risk and improves predictive accuracy when integrated into risk classification systems. The improved accuracy of risk assessment when including tumor biology via the 40-GEP test ensures more risk-aligned, personalized patient management decisions.

Integrating 40-GEP testing to improve clinical recommendations for adjuvant radiation for cutaneous squamous cell carcinoma: multidisciplinary consensus guidelines
Feb 2024
Combining clinicopathologic staging with the 40-GEP test allows for more accurate prognostic staging of cSCC tumors; this, in turn, improves precision in multidisciplinary treatment recommendations, including the use of ART. The utility of 40-GEP testing has been demonstrated in low-, higher-, and highest-stage cSCC tumors. Additionally, 40-GEP testing has shown greater specificity than current clinicopathologic guidelines in identifying patients at highest risk of nodal or distant metastasis who would most likely benefit from ART, as well as lower risk patients who would benefit less from such therapy. Appropriate use of 40-GEP testing involves a shared decision-making model between the multidisciplinary team and the patient with cSCC, taking into consideration many factors, such as the patient’s risk of metastasis, tumor and nontumor characteristics, and individual preferences.

The 31-gene expression profile test outperforms AJCC in stratifying risk of recurrence in patients with stage I cutaneous melanoma
Jan 2024
In a head-to-head comparison of DecisionDx-Melanoma to AJCCv8 staging for stage I cutaneous melanoma (CM) patients (n=6,883) two cohorts were analyzed using recurrence-free survival and melanoma-specific survival. Results from the study showed that DecisionDx-Melanoma significantly improved patient risk stratification, independent of AJCC staging in patients. In addition, DecisionDx-Melanoma provided greater separation between high-risk (Class 2B) and low-risk (Class 1A) groups than seen between AJCC stage IA and IB.
