Endometrial Cancer Presentation and Outcomes Based on Mismatch Repair Protein Expression From a Population-Based Study
The objective was to evaluate clinical characteristics and outcomes of endometrial cancers based on MMR status within a population-based study.
Methods
This was a retrospective population-based cohort study of all endometrial cancer cases from the Vancouver Coastal Health Authority region, evaluated for 4 MMR proteins using immunohistochemistry from 2012 to 2015. Patients were classified as MMR deficient (dMMR, any MMR protein absent) or MMR proficient (pMMR), Demographics, tumor characteristics, recurrences, and survival rates were compared according to MMR status.
Results
There were 892 patients, with 650 pMMR (72.5%) and 242 dMMR tumors. The dMMR group had more endometrioid tumors (87.6% vs 74.0%, P
