Objective:

To characterize the clinical behavior and molecular features of advanced-stage POLE-mutated endometrial carcinoma, particularly given its rarity, focusing on aggressive variants and co-occurring mutations.

Key Findings:
  • All tumors were high-grade (100% Grade 3) and predominantly endometrioid (86.7%).
  • Lymphovascular space invasion was present in all cases (100%).
  • Most tumors were mismatch repair-proficient (64%) and p53 wild-type (79%).
  • Co-mutations in the PI3K/AKT pathway were found in 29% of cases, with additional oncogenic drivers identified in 43%.
  • 21% of patients had brain metastases at diagnosis.
Interpretation:

The study highlights the clinical heterogeneity of advanced POLE-mutated endometrial carcinoma, suggesting that while many cases are indolent, some may exhibit aggressive behavior, including atypical metastatic patterns such as brain dissemination, which has implications for treatment strategies.

Limitations:
  • Small sample size limits generalizability and may affect the robustness of the findings.
  • Retrospective design may introduce selection bias, impacting the reliability of the conclusions.
Conclusion:

The findings underscore the need for nuanced risk stratification beyond POLE mutation status alone, particularly in identifying patients at risk for aggressive disease, which is crucial for optimizing treatment approaches.
