it was a journey for me. >>> we tracked down elliott sandler as well, that's robert's twin brother.s some remarkable memories of what happened in those days 60 years ago. did you know throughout your life that yoyour brother's role history? >> i had no idea until recently, until the book came out. i had no idea. >> you dedicated the book to robert sandler. there's a lot of patients in your back to that you told their stories. why robert in particular? >> robert was part of the first cohort of children to be treated with chemotherapy by sidney farber in boston in 1947. and he had a brief response to the drug and then relapsed, and unfortunately died soon after. what is amaze being this story, after adding more combinations of the very same kinds of drugs, eventually this disease that robert had, leukemia, became 80% curable by the mid 1960s and particularly by the mid 1970s, so it was an enormous victory for pediatric cancer. it was a beacon of hope. and richard nixon in launching the war in cancer on 1971 was really acknowledging in some sense that this victory had already occurred.
