Pioneer in Cancer Research Offers Powerful Testing for Cancer Treatment Selection

Dr. Robert Nagourney is an internationally recognized pioneer in cancer research and personalized cancer treatment.

He is the founder and medical director of Nagourney Cancer Institute (formerly Rational Therapeutics), Clinical Professor at the University of California, Irvine School of Medicine, and author of the book, Outliving Cancer.  

Over the past 20+ years, Dr. Nagourney and his team here at the Nagourney Cancer Institute have developed a laboratory technique, functional profiling, that measures how cancer cells respond when they are exposed to a wide variety of drugs and drug combinations.  

By using this approach, we determine in the laboratory the best drugs for each patient before they receive them.

The Science

Functional Profiling is the Key

With functional profiling , we can help discover the most effective and least toxic drug regimen for you PRIOR to initiating treatment.

We expose your living cancer cells in the laboratory to chemotherapy drugs, targeted agents and various combinations.

By using combinations of drugs found most effective in the laboratory, Dr. Nagourney has been able to double response rates and improve survival for his patients.

We can test most types of cancers, solid and hematologic (blood).

Samples are sent to us from all over the US and internationally.

Results are generally available within 7 days of receipt of your cancer sample in our laboratory.
