The rise in incidence of lymphomas in Europe 1985-1992.

A collaborative study was carried out of the descriptive epidemiology of the lymphomas from seven countries across Europe in the period 1985-1992. Careful attention was paid to sources of information and the data quality in close collaboration with expert histopathologists. The data were classified as non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD).

The changing incidence of lymphoproliferative disorders in Yorkshire.

Secular trends in the incidence of lymphoproliferative disorders on North and West Yorkshire and Humberside from 1985 to 94 were studied and changes in incidence by tumour subtype were analysed. Population-based data on the incidence of lymphoproliferative disorders were obtained from a specialist registry with a high level of ascertainment. Cases of chronic lymphocytic leukaemia and plasma cell myeloma were excluded and the remaining cases classified as Hodgkin's disease and non-Hodgkin's lymphoma (NHL).

Changing trends in the incidence of non-Hodgkin's lymphoma in Europe. Biomed Study Group.

Non-Hodgkin's lymphoma (NHL) is not a uniform disease entity, and in order to investigate the reported changes in incidence we have set up a study in seven population-based cancer registries in Europe. The study is designed to look at changes in the incidence of total NHL and disease subgroups using standard definitions and methodology. The registries are based in Leeds, Dijon, Kuopio, Odense, Florence, Eindhoven, and Ragussa.
