Population-based incidence of lymphoid neoplasms: Twenty years of epidemiological data in the Girona province, Spain

Abstract Background The aim of this study was to describe incidence patterns of lymphoid neoplasms in the Girona province (Spain) (1996–2015), and to predict the number of cases in Spain during 2020. Methods Data were extracted from the Girona cancer registry. Incident cases were classified using the ICD-O-3, third revision, and grouped according to the WHO 2008 classification scheme. Age-adjusted incidence rates to the European standard population (ASRE) were estimated and incidence trends were modeled using Joinpoint. Results 4367 lymphoid neoplasms were diagnosed in the Girona province. The ASRE for overall lymphoma was 37.1 (95% CI: 36.0; 38.2), with a marked male predominance in almost all subtypes. During 1996–2015, incidence trends remained stable for broader lymphoma categories. According to our predictions, 17,950 new cases of LNs will be diagnosed in Spain in 2020. Conclusions This ‘real-world’ data will provide valuable information to better inform etiological hypotheses and plan future health-care services.
