This chart shows the incredbile progress that has been made against childhood leukemia, specifically acute lymphoblastic leukemia. So if your child is diagnosed with ALL today, she probably has a greater than 90% chance of cure. 40 years ago the chance was more like 10%.
Chart is from last week's NEJM. ALL is the success story in cancer. Progress in other cancers has obviously been less impressive. Still, the success rate in childhood ALL is so great that much current research focuses on identifying "low risk" patients who will be cured with less-intensive regimens that have fewer adverse effects.
