Leukemia cases in USA

In the US, leukemia occurs more frequently in males than females (Call TG et al 1994; Cartwright RA et al 2002; McNeil DE et al 2002b). In addition, Caucasians are more likely to develop leukemia than African-Americans and Hispanics (McNeil DE et al 2002a; Xie Y et al 2003)

With the exception of ALL, leukemia is generally associated with aging. Furthermore, the behavior of leukemia in older individuals differs from that seen in younger people. For example, AML occurring in older individuals is more resistant to chemotherapy than AML in younger patients (Schoch C et al 2001).
