RESUMO
Endometrial cancer is one of the three common cancer of the female genital tract. According to the molecular char-acteristics of endometrial cancer.The cancer genome atlas proposed four molecular subtypes:POLE (DNA polymerase ε,POLE) mutant;microsatellite instability hypermutation;low copy number and high copy number/serous. Numerous preclinical and clinical researches indicated that PD-1/PD-L1 blockade therapy is a promising method for immunotherapy of endometrial cancer. The subtypes of POLE mutant and MSI hypermutation in endometrial cancers are characterized by high tumor mutation burden which may benefit from the treatment of PD-1/PD-L1 blockade. This molecular classification of endometrial cancer provides a new clinical treatment strategy for individualized immunotherapy.
