New findings could drive medical advances in genetic disorders that cause infertility

March 10, 2016

Dr. Gruber and his colleagues used a mathematical model to determine the medical and cost effectiveness of colorectal cancer genetic screening based on a simple family history. The study determined that the average cost effectiveness ratio, a measure of expenditure per life year gained by genetic testing, would be $26,000, significantly less expensive than the often-quoted benchmark of $50,000. The study further suggested that risk-assessment should begin between the ages of 25 and 35, and that genetic testing would be appropriate for those individuals whose mutation risk is 5% or greater. The study estimated that approximately 1% of the U.S. population over the age of 25, or 2.0 million Americans, would meet this criteria resulting in a potential market of more than $6 billion dollars for Myriad's COLARIS test. 

AACR President-elect Judy Garber, M.D., M.P.H., Director of the Center for Cancer Genetics and Prevention at the Dana-Farber Cancer Institute, hosted a conference call discussing the results of the study. The call is currently available online at>

"This will affect a wide population by changing our thinking about risk for colon cancer," said Dr. Garber.  "It is a huge step forward in terms of bringing the benefits of cancer genetics to the broader population using tests that have, in the past, been considered too expensive."
