But Chris, um, to, to you on a little bit of context in, in what you found in your study.

Sure.

Yeah.

Thanks, Jeff.

So as we've talked about, uh, you know, despite the guidelines that, uh, you know, we have from the COC or, um, in different parts of the world, you know, different, different, uh, uh, um, societies, we know that lymph node evaluation practices continue to vary pretty substantially across the US and across the world.

Um, and that's probably driven by the fact that we have no universal guideline.

And the, the question is, you know, really for us, um, what is the best lymph node dissection practice? Uh, and if you look into the literature, most of the data out there has focused on number of N2 lymph nodes that need to be evaluated.

And Chris, we'll, we'll turn to you on that question, and then also if you could weigh in on whether or not you feel the STS or just organizations in general, if, if we should, if we ought to be changing our guidelines now, you know, based off of these studies, or, or if we, there's still some other things that, you know, have to be investigated first, so.
