Using Tumor Biology to Provide Information on Risk of Recurrence and Metastasis

DecisionDx-Melanoma is a validated 31-gene expression profile (GEP) test that was developed to identify the risk of recurrence or metastasis including the likelihood of sentinel lymph node positivity for patients with stage I, II, or III melanoma and inform patient management decisions. The DecisionDx-Melanoma test accurately and independently predicts the risk of recurrence and metastasis, classifying patients as Class 1A (lowest risk), 1B/2A (increased risk), or 2B (highest risk).

Informs Two Key Clinical Management Decisions

Intensity of Follow-Up, Surveillance Imaging, and Referral to Surgical/Medical Oncology

Likelihood of SLNB Positivity Among Eligible Patients with T1-T4 Melanoma


Now Integrating 31-GEP with Clinicopathologic Factors

Using validated algorithms, the DecisionDx-Melanoma Class Score is now integrated with patient clinicopathologic factors to further individualize risk of recurrence (i31-ROR) and sentinel lymph node biopsy positivity prediction (i31-SLNB). 

  • 31-GEP Score + Clinpath factors = i31-ROR 

  • 31-GEP Score + Clinpath factors = i31-SLNB

DecisionDx-Melanoma Is Supported by a Robust Body of Evidence

Extensively studied in

9,000+ Patients &
35+ Publications

Well-studied, with over 9,000 Stage I-III cutaneous melanoma patients included in clinical studies and over 35 peer-reviewed scientific publications.

  • The risk of recurrence to guide management decisions has been clinically validated in 4 long-term multicenter studies showing consistent results.
  • To provide the likelihood of sentinel lymph node (SLN) positivity, the newly validated i31-SLN algorithm integrates the DecisionDx-Melanoma test score with clinicopathologic factors designed to provide a more precise and personalized risk prediction for patient management guidance.
  • Performance has been confirmed in 6 independent prospective studies.
Accurate prediction of recurrence and metastatic risk demonstrated in

2 Published Systematic Reviews with Meta-Analyses

Two published systematic reviews with meta-analyses showing that DecisionDx-Melanoma achieves the highest, Level 1A evidence, as an independent, significant predictor of recurrence and metastatic risk.
