"They did show a higher recurrence or progression rate with endometrial cancer than with AEH and that is consistent with other data," said Bakkum-Gamez, who added that the IUD method would not be appropriate for later-stage cancers, which tend to be more aggressive.
No adverse effects from treatment were noted, according to the researchers, who declared no conflicts of interest.
In background material, the researchers stated the progestin-releasing IUD should be effective in treating AEH and also early endometrial cancer, as long as those patients were evaluated with laparoscopy, ultrasound and MRI to make sure their cancer had not spread and there was no simultaneous ovarian cancer.
Nine of the women in the study successfully delivered babies.
The National Cancer Institute has more on endometrial cancer.
