Study summary

Pembrolizumab after surgery and radiation was linked to fewer relapses

Adjuvant pembrolizumab study · 32 people (16 in each group) · Published July 2025, Thyroid

What was tested

People with anaplastic thyroid cancer that had not spread far (stage IVB) got pembrolizumab after surgery and radiation, compared with similar past patients who did not.

What they found

All 16 people given pembrolizumab were alive at 2 years, against 52% in the comparison group.
The trial closed early because too few people enrolled, and the comparison group was from past records.

What it means

Promising but small. A randomized trial would be needed to confirm it.
