The area of alternative or dietary therapies for cancer and pediatric cancer specifically, is obviously a very controversial one. For me, as a physician, to recommend a treatment to a patient, I need to know there is good evidence that in patients who we know for sure have cancer, or particular kind of cancer. That means they had the right diagnostic studies. And, we know they have that cancer. And, we can measure it. We can actually measure what happens to that cancer. I need to know that they got what whatever this treatment was, and that it clearly reduced or had a positive effect on that cancer. And, that there was nothing else they were getting that could be doing that instead. And, that's the kind of standard that we apply to looking at the alternative therapies. And, preferentially, that we even have studies where some patients got it and some patients didn't. And, the ones who got this alternative or dietary therapy did better. If you look at very carefully, unfortunately, at the mass of information out there, that parents get besieged with about alternative therapies, you will very, very, very rarely find those kind of criteria met. And, that means, we can't tell whether if it's of any benefit. It's someones idea and they made some anecdotal observation. But, they haven't been rigorous. They haven't made sure those patients have a kind of cancer they're talking about. Or you can't measure whether it's shrinking or not. You may see them have side effects that get better. That might not have to do anything with the medication, okay. That they haven't really measured this properly in enough patients to be sure that they're dealing with something that works. So, I talk to the families about those criteria. I look up every single alternative therapy they provide to me, if I don't know about them, to make sure that there isn't such evidence. So, I take it seriously. I look it up. I try to find out about it. And, I come back and tell them what I've found out about it, so that they know that I've looked in it. And it's important. Because, occasionally maybe I'll find something that'll be exciting. As far as dietary therapy goes, actually I don't know of any really strong evidence of any specific diet any positive effect on shrinking a cancer. There is no question that one has to stay in a state of good nutrition, during the course of therapy. Because, if you get malnourished, you are more susceptible to infections, to side effects of the drug, etcetera. So, good nutrition is important. But, that's different than a dietary therapy causing the cancer to be killed. I know of none like that. So, that's the approach I take to families who bring this up.
