before those trials came out, there was a much higher rate of uh completion lymph node dissection even in in kids. And then after those trials, the rate has gone down, but it's still higher than what's done uh typically in adults.
I think the the answer would more likely just be to move forward with systemic therapy. Uh I don't think people would move forward with the completion lymph node at that time. You would just go with advent therapy.
for most children we can, um while the disease is thought to be more severe, you can still observe these patients with sentinel lymph nodes and not uh move forward with um completion lymph node dissection
Only 21% of patients that underwent completion lymph node dissection had additional nodes discovered and findings of additional nodal disease did not significantly correlate with recurrence.
Compared to adults, we know that childhood melanoma is associated with delayed diagnosis and therefore, not surprisingly, more frequently has nodal involvement.
