The heterogeneity of changes in incidence and survival among lymphoid malignancies in a 30-year French population-based registry.
Our specialized population-based registry has allowed us to explore changes in incidence and survival by subtype over the last 30 years. Between 1980 and 2009, 4790 cases of lymphoid malignancies were registered using the International Classification of Diseases for Oncology. The incidence rate of lymphoid malignancies was 20.5 per 100,000 inhabitants per year, and ranged from 0.1 to 4 according to subtype. Five-year net survival was 65%, and ranged from 41% to 93% according to subtype. We observed an increase in 5-year net survival between the periods 1980-1989 and 2000-2009 (58% vs. 70%). This was observed in most but not all subtypes. Our long-standing population-based registry allowed u…
Trends in excess mortality in follicular lymphoma at a population level
Background Since the 1990s and since the development of humanised monoclonal antibodies in 1998, the treatment of non-Hodgkin lymphoma has undergone profound changes. Follicular lymphoma (FL) was the first to benefit from this treatment, and several clinical trials have shown a significant improvement in overall survival, but little information is available at a population level. Objective Our objective was to estimate changes in FL-specific mortality at a population level, with an appropriate methodology. Methods Two French retrospective population-based studies on FL were conducted, one from 1995 to 2004, in 1477 patients, and one from 1995 to 2010, in 451 patients. Trends in excess morta…
Evaluation of the impact of therapeutic management on the survival and quality of life of patients with follicular lymphoma or diffuse large B cell lymphoma
In France, hematologic malignancies, which are the sixthmost common cancers, are amajor public healthproblem. This work aimed to study the impact of the therapeutic management on survival and healt-relatedquality of life (HRQoL) in patients with these hematologic malignancies. The first objective of this work is topresent an overview of the epidemiology of lymphoid malignancies with a study of changes in the incidenceand net survival in the Côte d’Or department between 1980 and 2009. The incidence, which has increased since1980, seems to have stabilized since the 2000s for some entities, including follicular lymphoma (FL) and diffuselarge B-cell lymphoma (DLBCL). Overall, we observed an imp…
Risk assessment of second primary cancer according to histological subtype of non-Hodgkin lymphoma.
Non-Hodgkin lymphoma (NHL) represents a heterogeneous group of diseases that are known to carry a considerable risk of second primary cancer (SPC). However, little attention has been paid to SPC risk assessment according to NHL subtypes. Data from 10 French population-based cancer registries were used to establish a cohort of 7546 patients with a first diagnosis of NHL (eight subtypes) between 1989 and 2004. Standardized incidence ratios (SIRs) of metachronous SPC were estimated. Among the 7546 patients diagnosed with a NHL, the overall SPC risk was 25% higher than that in the reference population (SIR = 1.25, 95% confidence interval 1.15–1.36). In univariate analysis, the SPC risk differed…
