Less may be more: smaller surgery for melanoma tested in 1,000-Patient trial

NCT ID NCT06673095

First seen Mar 28, 2026 · Last updated Jun 23, 2026 · Updated 17 times

Summary

This study tests whether removing a smaller border of healthy tissue around a melanoma (narrow excision) works as well as the standard wider excision. About 1,000 adults with early-stage melanoma will be randomly assigned to one of the two surgeries. The goal is to see if narrow excision can reduce complications and improve quality of life without increasing the chance of the cancer coming back.

What this could mean

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

Active substance

surgical excision (narrow margin vs wide margin)

What this could lead to

If narrow excision works as well as wide excision, it could become the new standard for early-stage melanoma, reducing surgical side effects and improving recovery.

What could go wrong

This is a Phase 2/3 trial, so results are not yet proven. Narrow excision might lead to higher local recurrence rates, and the study is still recruiting.

Conditions
