[Analysis of lymphoma incidence in Beijing, 1998-2010].
OBJECTIVE
To analyze the incidence trends and characteristics of lymphoma in Beijing, 1998-2010.


METHODS
Total of 9 763 new cases diagnosed as lymphoma in 1998-2010 were extracted from the population-based database of Beijing Cancer Registry, covering population of 151 601 066 person-years. Incidence, age-adjusted incidence, cumulative incidence, truncated incidence and annual percentage change (APC) were calculated. The gender-specific, age-specific and pathology-specific incidence trends were analyzed.


RESULTS
The incidence rate of lymphoma was 6.48/100 000 (9 763/150 720 187) during the period of 1998-2010, increased from 3.78/100 000 (410/10 850 626) in 1998 to 8.88/100 000 (1 111/12 518 114) in 2010 with an increasing rate of 136.17% (APC = 5.21%, P < 0.05). The incidence rate of Hodgkin lymphoma increased from 0.25/100 000 (27/10 850 626) in 1998 to 0.47/100 000 (59/12 518 114) in 2010 with an increasing rate of 88.00% (APC = 4.33%, P < 0.05). The incidence rate of non-Hodgkin lymphoma was increased from 2.89/100 000 (314/10 850 626) in 1998 to 5.93/100 000 (742/12 518 114) in 2010 with an increasing rate of 105.19% (APC = 4.19%, P < 0.05) . During the period of 1998-2010, the incidence of lymphoma was 7.78/100 000 (7 125/91 621 898) in urban areas and 4.47/100 000 (2 638/59 098 289) in rural areas, 7.40/100 000 (5 632/76 121 672) in males and 5.54/100 000 (4 131/74 598 518) in females.


CONCLUSIONS
The incidence of lymphoma keeps increasing in 1998-2010, and the incidence was higher in males than females, urban areas than rural areas. The incidence patterns of Hodgkin lymphoma and non-Hodgkin lymphoma were different.
