The aim of study is to present two successful cases of conservative surgical treatment of women with early-stage endometrial cancer who desired to have fertility in the two cases. A 32-year-old nulligravid woman had Stage IA endometrial cancer which was a 1.5-cm sized lesion confined to the left fundal side of the uterus. The other 35-year-old nulligravid woman had a 2-cm sized lesion suspicious for deep myometrial involvement suggesting Stage IB endometrial cancer. The women underwent hysteroscopic complete resection of tumor with safe resection margin just after laparoscopic tubal ligation, followed by insertion of a progesterone-releasing intrauterine device. The patients have no evidence of recurrence for 26 months and 27 months of follow-up, respectively. Hysteroscopic complete resection of tumor with safe margin combined with bilateral tubal ligation, followed by a progesterone-releasing intrauterine device could be a good option for early-stage endometrial cancer.
