Summary

Story summary

A retrospective study analyzed 29 uterine undifferentiated/dedifferentiated carcinoma (UDEC) cases diagnosed from 2003–2022.
Specimens came from formalin-fixed, paraffin-embedded (FFPE) tissues, with DNA from peripheral blood or matched non-neoplastic tissue.
The study used whole-exome sequencing and a triple-caller approach to detect variants and endometrial mutational signatures (POLD1).
Mismatch repair (MMR) protein expression was assessed with antibodies; antigen retrieval used high temperatures.
