chronic lymphocytic leukemia
"Due to my having a variant GI system (with its own side-effects), my oncologist, in an abundance of caution, started me on Imbruvica 1 capsule in the AM, daily. Literally within days, the SIGNIFICANTLY large lymphs in the front and rear of my neck, disappeared. WOW! 
MY WBC's skyrocketed, but that is typically expected due to the mechanisms by which Imbruvica works. Oversimplifying here -- the abnormal (cancerous) cells, congregate in the lymphs. Imbruvica forces those abnormal cells out into the bloodstream, where they can be attacked and starved of the BTK protein, which they need to thrive and propagate. The "dead" abnormal cells are then flushed out of the body.
After 2 months dose upped to 2 capsules daily, and still tolerating well."
