If I'm reading this right it looks like 3 yr survival was 30-50% in high risk melanoma patients in the late 1960s to early 1970s: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1344342/

That is pretty much the same as in your paper. Not sure how comparable those patients are though.

Thanks, do you have one for melanoma in mind for comparison to that study when you say "used to be lethal".

Ok, mostly there. Will try to find more.
