TP53 and endometrial carcinoma: The study for the first time revealed that endometrial carcinoma consists of four intrinsic molecular types: POLE mutated (POLEmut)/ultramutated; mismatch repair (MMR) deficient (MMRd)/microsatellite instability‐high (MSI‐H)/hypermutated; p53 abnormal (p53abn)/copy number high; and copy number low/no specific molecular profile (NSMP).
