Independent study shows favorable long term prognosis for CP-GEP Low Risk melanoma patients

ROTTERDAM, Netherlands and SAN DIEGO, March 17, 2023 /PRNewswire/ — SkylineDx, an innovative diagnostics company, focused on research & development of molecular diagnostics for oncology and inflammatory diseases, today announced the publication of an independent study showing that gene expression profiling (CP-GEP model) can be used to identify primary cutaneous melanoma patients with a high risk for disease recurrence.
The University of Tuebingen (Germany) study analyzed 543 patients diagnosed with stage I/II primary cutaneous melanoma between 2000 and 2017. It found that when combined with clinicopathologic factors, the CP-GEP model can be used to stratify these patients into high risk and low risk cohorts for disease recurrence. Specifically, the patients determined to have Low Risk have an almost five times favorable 5-year recurrence free survival (RFS) over the CP-GEP High Risk patients in stage I/II melanoma, with 93% of low-risk patients are recurrence-free 5 years after diagnosis [2].
Although the research was focused on patients with a negative sentinel lymph node biopsy (SLNB), a separate analysis on patients with very thin melanomas and unknown SLNB status also demonstrated CP-GEP’s ability to significantly stratify CP-GEP Low Risk from High Risk patients among this group. The publication supports the value of diagnostic information over a long-term period following the initial diagnosis. Outcomes of this study were published earlier this year by the European Journal of Cancer [2].
