Mortality reduction and cost-effectiveness of performing hysterectomy at the time of risk-reducing salpingo-oophorectomy for prophylaxis against serous/serous-like uterine cancers in BRCA1 mutation carriers.
Mutations and amplifications of the PIK3CA gene are relatively infrequent in human cervical and endometrial cancers; however, PIK3CA gene alteration may still play a role in some subset of uterine cancers.
Somatic missense mutations in the Ser/Thr protein phosphatase 2A (PP2A) Aα scaffold subunit gene PPP2R1A are among the few genomic alterations that occur frequently in serous endometrial carcinoma (EC) and carcinosarcoma, two clinically aggressive subtypes of uterine cancer with few therapeutic options.
This review briefly summarizes the current information on the pRb1-cyclin D1-cdk4/6-p16(INK4A) alterations in sporadic uterine cancer, placing emphasis on the influence on the dualistic model of endometrial carcinogenesis.
No differences in MBL2 genotype or in allelic or haplotype frequencies were found between HPV patients who developed cervical uterine cancer and those who did not.
Endometrial cancers, and in particular endometrioid carcinomas, should undergo immunohistochemical testing for mismatch repair proteins.Uterine cancers with documented mismatch repair deficiency are candidates for treatment with programmed cell death protein 1 inhibition.Genomic testing of recurrent, advanced, or metastatic tumors may be useful to determine whether patients are candidates for precision therapies.
Our work also suggests that targeting HMGA1 could be effective adjuvant therapy for more aggressive uterine cancers and provides compelling data for further preclinical studies.
