Could a simple biopsy replace major surgery for multifocal breast cancer?

NCT ID NCT00417495

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This completed Phase 2 trial looked at whether the sentinel lymph node technique—a less invasive way to check if cancer has spread—works for women with multifocal breast cancer (more than one tumor in the same breast). 216 women with early-stage, node-negative multifocal breast cancer took part. The goal was to see how often doctors could find and correctly identify the sentinel node, which could help avoid more extensive lymph node removal.

What this could mean

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

What this could lead to

If successful, this could confirm that sentinel lymph node biopsy is a reliable option for women with multifocal breast cancer, potentially sparing them from more invasive lymph node removal.

What could go wrong

This is a completed Phase 2 trial, so results are not yet widely adopted. The technique may not be as accurate in multifocal cases as in single-tumor cases, and the study's findings need confirmation in larger trials.
