Endometrial cancer is one of the most frequent gynecological cancers in women. According to a recent national survey, endometrial cancer has increased rapidly in the past 30 years in Taiwan and the incidence of endometrioid adenocarcinoma has increased more and more quickly in younger age. Although total hysterectomy is usually recommended to eradicate the malignant lesion, this procedure may not be suitable for a young nulliparous woman, especially when the endometrial cancer is early stage. We report a case of consecutive successful pregnancies by in vitro fertilization and embryo transfer (IVF-ET) after conservative management of early stage endometrial carcinoma. To our knowledge, this is the first such case ever been reported in Taiwan. We believe this case will be very encouraging to younger women with early stage endometrial cancer.
