Three-year NADINA data showed something that shouldn’t happen: near-complete responders did substantially worse than partial responders — 62.3% versus 87.5% recurrence-free survival. One design feature separates NADINA from every neoadjuvant melanoma trial before it. NADINA mandated full lymph node dissection in every patient; PRADO left the basin alone in major responders. I think that may be the explanation, and nobody raised it.
