Hi,
I would caution against expecting "incredible results" as you mentioned. This is merely a diagnostic test, not a treatment.
Having said that, I think it makes so much sense to try it. There's no downside except the financial cost.
My mom tried it and it indicated she'd be most sensitive to two particular combinations. She's on her second cycle of cisplatin+gemzar now. While it's too early to know how well it is working, based on an Xray after the first cycle the oncologist said it's looking "a bit better". Mom's side effects of cough and short breath (probably caused by pleural effusion) have decreased noticeably.
Importantly, the assay indicated what Mom would probably NOT be sensitive to. One of the indicated drugs was carboplatin. This is a very important point, because there's a good chance that carboplatin+gemzar would've normally been prescribed as the first line treatment. Personally, I feel that this is the big value of using an assay to try to predict which drugs to use.
Hang in there and Best of luck.
