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-1990s. The 5-year relative survival was 58% for lymphoid and 35% for myeloid neoplasms. Survival improved during 1990-2004 for diffuse large B-cell lymphoma, follicular lymphoma, acute myeloid leukemia, chronic myeloid leukemia, and myelodysplastic syndromes (p < 0.001) and declined with advancing age for all subtypes (p < 0.001). Female sex was associated with higher survival for most myeloid subtypes. The results represent a rare epidemiological characterization of the whole range of LHN according to WHO subtypes.
