Summary
Gene expression profile (GEP) testing for cutaneous melanoma shows promise but requires more evidence for routine use. Current GEP tests have limitations, especially for early-stage disease, necessitating further research before widespread clinical adoption.
Area of Science:
- Oncology
- Genomics
- Dermatology
Background:
- Prognostic gene expression profile (GEP) testing is increasingly used for cutaneous melanoma (CM).
- Its integration into standard care is not yet established.
- Guidelines are needed for its appropriate use in CM management.
Purpose of the Study:
- To develop guidelines for integrating GEP testing into CM patient management.
- To review existing GEP test data and define performance criteria.
- To establish current recommendations and future research directions for GEP testing in CM.
Main Methods:
- National Melanoma Prevention Working Group (MPWG) members and international specialists participated.
- Two online surveys were conducted.
- A summit meeting was held, and published data from 2015-2019 were reviewed.
Main Results:
- MPWG members are optimistic about GEP testing's potential for risk stratification.
- Current GEP test utility is limited by performance in stage I CM.
- Studies often lack comprehensive clinicopathologic correlation and survival outcome comparisons.
Conclusions:
- More evidence is required to support GEP testing for guiding sentinel lymph node biopsy, surveillance, and adjuvant therapy.
- Further research is recommended to validate GEP tests' clinical applicability.
- Patient management decisions using GEP testing should involve thorough discussion of limitations.
