Twenty women with endometrial cancer, FIGO IA (1988) (FIGO staging was essentially defined post-surgically), instead of the pathogical specimen before surgery without myometrial invasion were estimated by MRI under 40 years at Gifu University Hospital, Japan from 1988 to 2009.

Immunohistochemical PTEN retain in tumor cells before MPA treatment (8/10) was significant better correlation with pregnancy and delivery rate than of lost cases (1/5) in non-obese women (P < 0.05).
