Caris Life Sciences molecular cancer profiling

Posted by beebe @beebe, 5 days ago

Anyone had their cancer analyzed by Caris Lifesciences to look for genetic mutations which chemo therapy could target? I have also read about functional testing, (PARIS and Nagourney Cancer Institute’s functional profiling analysis), which I am not sure is developed enough yet to work for all cancer types.

Interested in more discussions like this? Go to the Cancer Support Group.

beebe, I had the profiling of my tumor done (not by Caris). They note the genetic mutations of your tumor. They match your mutations to any chemotherapeutic agent that has been used against that mutation. You end up with a list of chemotherapy drugs that have been used successfully, used unsuccessfully and those that are being tested in clinical trials. All three chemotherapeutic drug that were pressed upon me had already been tested against my mutations and had failed to affect the mutation. At University of Pittsburg they refused to treat me without a port for one agent, oral and injectible drugs for two others without somatic testing. I was surprised to find that it wasn't a choice I would be allowed to make. I found a proton center that would treat with chemo. And had successful treatment without useless chemotherapeutic side effects.
There may be no chemo information on some of your mutations. The data base has enlarged enormously in the seven years since my somatic testing. I think this testing is crucial to your experience as a cancer patient. I suggest that you accept all testing available. Best wishes

I was diagnosed bile duct cancer and had liver resection at Montefiore in Pittsburgh in Sept. 2024
Now snowbird but having bad side effects from chemo pills so now they want me to try Gemcitabine IV UGH!!

Foundation 1 did my testing.

Sorry to hear you are not tolerating the chemo pills, hope at least the proposed IV tx works for you and is more tolerable.

I did not realize there were so many companies that do molecular testing. Will have to leave it to my Doctor to select the one he thinks will give the most useful information. Reading the websites the science jargon is all gobbely gook to me!

beebe, good thinking. The financial help section is clear of jargon. But, of course, yield to the md.
