Kari Ring

Kari Ring is a gynecologic pathologist who has contributed to pathological classification and molecular subtyping of uterine carcinosarcoma (malignant mixed Mullerian tumor), demonstrating that heterologous versus homologous sarcomatous elements do not meaningfully predict outcomes and that molecular classification by POLE/MMR/p53 IHC is more clinically actionable. She has published studies on implementing molecular classification of endometrial cancer in routine pathology practice, including validation of surrogate IHC markers for POLE mutation and TP53 aberrations.
