Summary: Independent histopathological review reveals clinician-dependent diagnostic discordance that
echoes prior studies.
› Our Non-Guided Patient Journey Model highlights the impact of diagnostic variability on
subsequent surgical management decisions.
› Procedure probability rates in GEP-Guided vs. Non-Guided models indicated 69.3% of patients
would move from an inconsistent treatment path to a consistent treatment path with use of GEP.
› The 23-GEP can optimize surgical management by minimizing clinician-dependent variability in
difficult-to-diagnose melanocytic lesions.
