Correlation of <i>PD‐L1</i> Expression With Microsatellite Instability and p53 Status in Endometrial Cancer: A Clinicopathological and Molecular Analysis

No molecular marker demonstrated a significant association with recurrence risk (p > 0.05), in contrast to the FIGO stage, which showed a significant correlation (p < 0.001). Although PD-L1 expression was rare, it was significantly associated with microsatellite instability, highlighting the potential of molecular classification to identify candidates for immunotherapy. However, the low frequency of PD-L1 positivity and the small sample size warrant caution in interpreting these findings, and further research is needed to confirm the clinical relevance of PD-L1 in endometrial cancer.
