Details and patient eligibility

About

This study is to explore the driving genes and the molecular mechanism of malignant transformation of adenomyosis. This study acquired the formalin fixed paraffin-embedded (FFPE) tissue of patients pathologically conformed endometrial carcinoma arising in adenomyosis (EC-AIA) treated at Peking Union Medical College Hospital from July 15, 2017 to July 15, 2019. The formalin fixed paraffin-embedded tissues from patients pathologically diagnosed with adenomyosis during this time period were also included as control specimens. The eutopic endometrium, normal adenomyosis tissue, and EC-AIA tissue were harvested from the FFPE tissue from patients with EC-AIA. The normal eutopic endometrium and normal adenomyosis tissue were obtained by laser microdissection. The driving genes and potential molecular mechanism of EC-AIA will be found by the technology of whole exome sequencing and transcriptomics (RNA-sequencing).
