In an animal study, researchers at UT Southwestern Medical Center have found that a mutation in a single gene can cause endometrial cancer that is responsive to a specific drug therapy.

The researchers said that the finding suggests that eventually it might be possible to screen women with endometrial cancer to see if they have that mutation and use the drug as targeted therapy.

"Our data suggest that deficiency of this gene can indicate both how aggressive an endometrial tumour will be and how well it might respond to a specific class of drugs," said Dr. Diego Castrillon, assistant professor of pathology at UT Southwestern and senior author of the study.

"Some early clinical trials have shown that about one-fifth of women with endometrial cancers respond to a group of drugs called 'rapalogs.' Unfortunately, it is not currently possible to predict which women these are," Dr. Castrillon added.

Endometrial cancer affects the lining of the uterus. This cancer is the most common cancer of the female reproductive tract and is usually detected when a woman complains of excessive bleeding. About one-third of ovarian cancer cases are believed to begin as endometrial cancer, Dr. Castrillon said. The median survival of women with advanced endometrial cancer is one year.
