My dad was fortunate enough to get into a trial at Sloan for Obinutuzumab for Chronic Lymphocytic Leukemia. At the moment, after 6 weeks of treatment, the percent of cancerous cells in his bone marrow has gone from 95% to 5%. The treatment was very intense as it overloads the kidneys on the first few treatments due to the dramatic amount of cells being flushed out. This is a cancer for which there was not much treatment previously other than extreme chemotherapy which still left little hope for complete remission. A family friend was also treated for Non-Hodgkins' lymphoma on another drug trial and she's now in full remission.

my uninformed impression is that there's a lot of new cancer treatments happening now that can turn the tide for a lot of types of cancer.
