Abstract 5207: Comparison of subtype-specific incidence rates of lymphoid malignancies in Hong Kong and the United States

Clinical studies of lymphoid malignancies (LMs) have suggested that the descriptive patterns of these neoplasms differ in East Asia compared to Western populations. However, there are very limited available data on population-based, subtype-specific incidence rates of LMs in the East Asian population, particularly in Chinese. Using data from the Hong Kong (HK) Cancer Registry and the United States (U.S.) Surveillance, Epidemiology, and End Results Program, we calculated and compared age-adjusted incidence rates of LM subtypes in HK to those in Whites and Asians living in the U.S. Overall and sex-specific rates were calculated for the period 2001-2010. In order to formally compare the incidence rates between HK and the U.S., standardized rate ratios (SRRs) were calculated comparing the age-adjusted rates of each subtype for U.S. Whites and U.S. Asians in the SEER 13 database to HK. The incidence of most subtypes was low in the HK population, with rates
