Leukemia Leukemia is a cancer of the white blood cells and bone marrow. Worldwide, around 352,000 people were estimated to have been diagnosed with leukemia in 2012.29 In 2014, it is estimated that there will be 52,380 new cases of leukemia and an estimated 24,090 people will die of this disease in the US.40 In 2011, 8,616 people in the UK were diagnosed with leukemia (all subtypes combined) and there were 4,603 deaths from leukemia. In Europe, around 82,300 new cases of leukemia were estimated to have been diagnosed in 2012. There are four main subtypes of leukemia: acute myeloid leukemia, acute lymphoblastic leukemia, chronic myeloid leukemia, and chronic lymphocytic leukemia. About 20–1,000 mg/L LBPs inhibited the growth of human promyelocytic leukemia HL-60 cells in a dose-dependent manner.44 LBPs also induced the apoptosis of HL-60 cells as determined by DNA ladder and terminal deoxynucleotidyl transferase dUTP nick end labeling assays.
