Hi Vanessa,
First let me start by saying I'm terribly sorry to hear about your brother! The good news is at 37 years old he should have a lot of fight in him!
Has he considered holistic approaches? There is a great place in Clearwater, FL that I think you may be very interested in seeing. It's called Utopia Wellness. Dr. Garcia has helped a ton of patients cure cancer of all types! In addition, I've heard the treatments really help a lot with symptom management and overall well being! You should be able to do this on top of the chemo treatments, just give them a call or schedule a consultation.
As for other chemo options, you could consider IPT (Insulin Potentiation Therapy). With IPT the insulin works on the cell membranes and allows chemotherapy to target cancer cells. Thus, it is the chemotherapy that kills the cancer cells, however, because of the insulin, the amount of chemotherapy needed is greatly reduced, meaning the side-effects of the chemotherapy are greatly reduced. Thus, the chemotherapy is much more potent (thus the word: potentiation), much less chemotherapy is needed, and far less side-effects are experienced.
Regards,
Mike
