molecular tumor profiling

i have the same question. i know scubadan had a genomic (genetic? not sure what the right word is) profiling test done recently, which i remember from his earlier post is supposed to be a relatively new type of test. i've been wanting to ask him about the exact name of this test. there are others indeed who have done similar profiling tests. but my question has always been: from what i understand, these tests help determine the efficacy of certain chemo medications. but aren't there only about 5 or so types of chemo medications out there? if the number of options is limited, i am puzzled about how useful detailed genetic/genomic profiling can be?

Dear Friends,

As I understand it there is three types of testing.

1. Genetic test to determine whether you have certain genes that increase the possibility of cancer in you or your relatives.

2. Genomic testing is performed when you already have cancer and they look into your cancer's DNA to see if the cancer is a certain type. This is important because certain type of colon cancers will not react to certain chemo drugs.

3. Chemo sensitivity test is done after a small piece of the cancer is removed. The want a small piece of the living cancer within 24 hours. They will keep these cells alive and test different chemo dugs or combination of different drugs and see how the cancer cells react. 

I'm having the last one done or go to the Rational Therapeutics website.

 

 

O'k, Laz, this is a good starting point for orientation. I will sit down and do some research now. Please keep us posted about the results of your chemo sensitivity test.

chemo sensitivity test

Does anyone know where Chemosensitivity test with patient samples are done in India?

I know a place here in California, but they need to get the sample in 24 hours after removal. The test is $4000. 

Do an Internet search, maybe there are options in India as well. 

Good luck,
