Relationship between Malignant Transformation of Endometriosis and Genetic Alterations of K-ras and Microsatellite Instability
·doi:10.15369/sujms1989.16.47

Several genetic alterations have been associated with the malignant transformation from endometriosis to ovarian cancer. However, the role of each genetic alteration in this multi-step process of tumorigenesis has not been clarified. Region…
