Leukemia cells may hide in frozen ovarian tissue, small study warns

NCT ID NCT04679285

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

Summary

This pilot study looked at ovarian tissue from 9 young women with acute myeloid leukemia who had it frozen to preserve fertility before a stem cell transplant. Researchers checked the frozen tissue for any leftover leukemia cells. The goal was to see if the tissue might be safe to use later to help these women have children.

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 help doctors know whether it is safe to use a patient's own frozen ovarian tissue to restore fertility after leukemia treatment.

What could go wrong

This is a very small pilot study (9 people) that only looks for leftover cancer cells in tissue. It does not test whether transplanting that tissue is safe or effective.
