Leukaemia
Neither, really. Leukaemia is a cancer. Cancer is the abnormal growth and accumulation of cells from (in this case, I presume) the human body. Humans are eukaryotes. The leukocytes that grow out of control in leukaemia are eukaryotic cells. You only really use Gram stain on prokaryotic cells. That said, I should imagine that leukaemia is Gram-negative, because the stain picks up bacterial cell wall, which the eukaryotic leukaemia doesn't have.
I think that question is impossible to answer as there are different types of leukaemia. Treatments are improving all the time. Many people die from other causes whilst having leukaemia.
