Not specifically but I wouldn't be afraid to try fenbendazole. Leukemia is a blood cancer and not a tumor but it's still a form of cancer so there would be nothing to lose. Fenbendazole is totally safe so it won't hurt to try it.
Wait, small point of order, leukemia does originate in the bone marrow, which is the spongy tissue inside the bones where blood cells are produced. However, it's considered a blood cancer because it affects the blood cells - specifically, the abnormal white blood cells produced in the bone marrow eventually enter the bloodstream, causing problems throughout the body. So in that sense, it's both a bone marrow disease and a blood disease, but it's usually classified as a blood cancer because of the effect on the blood.
