english: There is no surgery I have ever performed for a sarcoma patient that has ever been guided by a randomized controlled clinical trial, what we consider the best kind of population-based evidence in medicine.
non_english: Ne postoji nijedna operacija koju sam izveo na obolelom od sarkoma koja se vodila nekim kliničkim ispitivanjem na nasumičnom uzorku, što smatramo najboljom vrstom dokaza na populaciji u medicini.
