But first, I want to start with a publication from JCO, Journal of Clinical Oncology, Oncology Practice, about the neutropenic diet.
This was a meta-analysis, and so the neutropenic diet, as they describe, is pretty commonly described as not eating raw fruits or vegetables.
And there's one takeaway from this study, which is, you know what, there's no difference in neutropenic diet versus kind of the common sense diet, right? What they call a liberalized diet, where you kind of eat what you want, but still use the common sense, like what FDA says, don't eat raw meat, eat fully cooked meat, but you can eat raw fruits and vegetables as long as you wash them, okay? That's one takeaway, and that's the takeaway that I kinda saw online.
The other takeaway is this is maybe some of the best evidence we have for a neutropenic diet in the patients at the greatest risk of neutropenic infections, which would be those with hematologic malignancies and stem cell transplant.
And so that analysis in this, in the hematologic malignancies and stem cell transplant is based on six studies.
Among these six studies randomized in those studies to the neutropenic diet and 419 to the liberalized diet.
And of these six studies, there are, let's see, four that were patients post-transplant and two, for patients receiving acute leukemia.
So it's your take, how much of that is just acute leukemia? How much of that is stem cell transplant? It's a little bit hard to say.
The study that has the biggest impact on that was in transplant patients after acute leukemia.
It said that there wasn't a significant difference in risk with the liberalized diet, but there was a strong trend, like the hazard ratio Or the 95% constant upper bound was 1.01.
It does look like the common sense practice of avoiding raw fruits and vegetables, especially in America these days with the cryptosporosis risk of lettuce and things like that.
We've had a lot of these studies before, but because they're so small, they have not shown, you know, and some of them have probably been overconfident in saying there's no benefit of the neutropenic diet.
