I am currently a patient of Dr. Davendra Sohal at the Cleveland Clinic Taussig Cancer Center. Prior to that I was a patient at the Mentor UH/Lake Hospital Seidman Cancer Center.
Dr. Sohal is good, but not as aggressive as my desires are. If I all things were equal (but they seldom are) I would go to MDA. From what I read here, they are far more knowledgeable and aggressive. Up until the Fat Lady (valkyrie Brünnhilde) steps up for her aria, I'm going to try everything I can.
You need to determine what you expect from an oncologist and find one who delivers. And remember, this is all about the life (quality and quantity) of a loved one - accept nothing but the best.
Forget the statistics. Some of us pass only weeks after initial diagnosis. Others live for 10+ years. Since you and your husband are the "nerds", don't get hung up with "analysis paralysis". Do the best you can and don't look back. Right now I'd say that getting started now is more important than finding the best treatment. Have your FIL keep a journal with dates and people and what was discussed, symptoms, what he ate, how much he moved arougn, Depending on the diagnosis, he may be able to slide out with a "simple" surgical procedure. Or he may have to undergo chemo (cisplatin/gemcitibine is the "standard" for initial chemo). Once you get a firm diagnosis, search in here for more details/recommendations.
You can reach any of us privately by e-mail if you don't want to go public.
You are in good hands here and better hands at MDA. Get moving. You are at step 1. There's more for you to learn.
