To investigate the genetic alterations during transformation of ovarian endometriosis into cancer, the authors analysed mutations of tumour-related genes (PTEN and p53) in EAOC cases (n=23, group 1), including 19 cases which were detected co-existence of endometriosis and cancer and four cases which fulfilled the histological criteria in malignant transformation of endometriosis (OCEMs), and in atypical hyperplasia ovarian endometriosis (aEMs) (n = 10, group 2), as well as in solitary ovarian endometriosis (EMs) (n = 20, group 3), simultaneously, to study the correlation of the two genes in the development and progression of the ovarian endometriosis malignancy.
