I was just reading the section in Step Up to Medicine on CML, and in the treatment section it says " Chemotherapy may control symptoms before the acute phase develops, but this is a progressive disease with no cure." Also says "survival is unpredictable, but the average is 3 years." This book was published 2008, a mere three years ago. Now in the MKSAP explanation for a question on CML, it says "Imatinib mesylate (Gleevec) treatment for chronic myeloid leukemia is associated with complete hematologic remission in 95% of patients." We've all heard the Gleevec story, but seeing the contrast is pretty amazing. THAT is what medicine is about, and one of the many reasons I love this field 🙂
