Doctors Link Ovarian Cancer Survival Rate with Two Proteins

by: cancercompass

Researchers in Houston have discovered that higher levels of two specific proteins increase ovarian cancer survival rates.

Doctors from the University of Texas M.D. Anderson Cancer Center looked specifically for the Drosha and Dicer proteins in 111 women diagnosed with advanced epithelial ovarian cancer.

Women who had ovarian tumors with high levels of the proteins survived a median of 11 years, while those with lower levels survived for a median of approximately 2.6 years.

Both proteins play a key role in RNA interference, a naturally occurring cell system that turns genes on and off.

CNN reports that the study is the largest to link RNA interference with cancer survival rates, and that researchers also found that higher levels of Dicer protein meant higher survival rates for breast and lung cancer patients.

The study was published in the New England Journal of Medicine.
