Anyone ever heard of tumor profiling or Rational Therapeutics?

Does anyone know anything about testing the actual tumor to determine which chemo will work?  I went through 3 of 6 rounds of neoadjuvant chemotherapy (TAC) when I realized that not only was my tumor not shrinking, but was growing (began at about 3 cm, when removed was 4.8).  Sometimes it pays to be flat chested!  I called my doc and he wanted an MRI asap.  This is where I was proven correct.  Apparently I am in the 1-2% category where my particular regiment of chemo for my particular cancer does NOT work.  As anyone would be, I was very upset. 

Anyway and needless to say, the chemo stopped and surgery was scheduled (had it 10 days ago).  My doc suggested I have the tumor sent to a lab in California called Rational Therapeutics.  Here they test the tumor and find out which regiments of chemo it is resistant to and which will kill it.  To me, this sounds like something that should be done with each and every cancer, but it is rarely done.  Of course, I agreed.  Anyone ever done this?  What were your results?

I'm so thankful I did the chemo prior to surgery, otherwise I would have had surgery, then done the six rounds of TAC, and never known it did not work.  I'm also thankful that, amazingly, the cancer had not spread to the nodes, even being a grade 3.  That was nothing but answered prayer.
