ROTTERDAM, Netherlands and SAN DIEGO, April 5, 2024 /PRNewswire/ -- SkylineDx is pleased to announce two forthcoming scientific publications at the European Association for Dermato-Oncology congress, April 4-6, 2024. These publications show Merlin test's (CP-GEP model) ability to identify early-stage cutaneous melanoma patients at high risk for relapse.
The first is a study led by researchers from Denmark, Weitemeyer, et al, that examined over 400 patients who underwent a sentinel lymph node biopsy (SLNB) between 2010 and 20151. All the biopsies were defined as negative for metastasis. The CP-GEP model was applied on the prospectively collected, archived tumor specimens and its outcome correlated with the patients' clinical data for 5 years following diagnosis (for both recurrence free survival and overall survival). The findings indicate that the model effectively stratifies node-negative patients in two groups: patients at low - and high risk for disease progression. In the high-risk group, 17.2% experienced a recurrence of the disease in the 5-year following diagnosis compared to 8% in the low-risk group.
While a nodal assessment by means of the SLNB surgery remains the gold standard for clinical staging of cutaneous melanoma, not all eligible patients might undergo this invasive procedure. Node biopsies in the head and neck location may be challenging due to the regional course of nerves and lymphatic drainage2. The second study, led by Dr. Amaral from University of Tuebingen, Germany, assessed the performance of the CP-GEP model in a group of patients that did not undergo the SLNB procedure. More specifically, she focusses on a subgroup of melanoma patients with a primary tumor in the head and neck region. CP-GEP showed to be able to identify patients with a high risk for recurrence in this independent dataset. The authors concluded that the model demonstrates potential to risk stratify patients with early-stage melanoma3.
"Both studies provide promising insights into CP-GEP's capacity to stratify patients based on their risk for disease progression and its potential value to support treatment and surveillance strategies for early melanomas." says Jvalini Dwarkasing, Chief Scientific Officer at SkylineDx .
About CP-GEP
CP-GEP is a non-invasive prediction model for cutaneous melanoma patients that combines clinicopathologic (CP) variables with gene expression profiling (GEP). This model is able to identify cutaneous melanoma patients at low-risk for nodal metastasis who may forgo the sentinel lymph node biopsy (SLNB) procedure. The CP-GEP model was developed by Mayo Clinic and SkylineDx BV and it has been clinically validated in multiple studies More information (including references) may be obtained at www.falconprogram.com. The test has been launched in the United States and Europe as Merlin test. SkylineDx collaborates with diagnostic service providers globally to bring this test to market and increase the access. In the United States, Tempus is commercializing Tempus Merlin test.
Quest Diagnostics launched their own LDT version of the CP-GEP model in the United States under the brand name MelaNodal Predict.
