Gene test may spare melanoma patients unnecessary surgery

NCT ID NCT04759781

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study is testing a gene signature (the Merlin Assay) to see if it can accurately predict whether melanoma has spread to nearby lymph nodes. Researchers are enrolling 1,820 newly diagnosed melanoma patients who are scheduled for a sentinel lymph node biopsy. The goal is to determine if the test can identify low-risk patients who might safely skip the biopsy, leading to more precise staging and fewer invasive procedures.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Merlin Assay (gene signature test)

What this could lead to

If successful, this test could help many melanoma patients avoid unnecessary lymph node biopsies by accurately identifying those at low risk of spread.

What could go wrong

This is an observational registry study, not a treatment trial. The test may not prove accurate enough in practice, and results may not change standard care immediately.
