Incidence and survival of lymphohematopoietic neoplasms according to the World Health Organization classification: a population-based study from the Victorian Cancer Registry in Australia.

Abstract

We studied the incidence and relative survival of 39 837 cases of lymphohematopoietic neoplasms (LHN) reported to the Victorian Cancer Registry during 1982-2004, classified according to the World Health Organization (WHO) classification. We modeled excess mortality using Poisson regression to estimate differences in survival by age, sex, and time period. Age-standardized incidence rates varied across subtypes of lymphoid and myeloid neoplasms. All major subtypes predominantly affected the elderly except Hodgkin lymphoma (incidence peaks at 20-24 and 75-79 years) and acute lymphoblastic leukemia (0-9 years). After an initial rise, overall lymphoid and myeloid incidence stabilized in the mid-1..
