Abstract Background. Hodgkin lymphoma (HL) in children constitutes approximately 30% of all pediatric lymphomas in Sweden. The chance of cure is high, but the frequency of late effects has been considerable. Over recent years, efforts have been made to reduce treatment with maintained survival. Material and methods. All patients 0-17 years, identified in the Swedish Childhood Cancer Register as diagnosed between 1985 and 2009, were included. The material was analyzed using descriptive statistics and for survival estimates the Kaplan-Meier method was used. Results. Three hundred and thirty-four patients were identified during this time period. The median age was 14 years. Male sex was over-represented, especially in lower age groups and in nodular lymphocyte predominant Hodgkin lymphoma (NLPHL). In nodular sclerosis and in age group 15-17 years, female sex dominated. Most of the cases presented in stages I or II. B-symptoms were present in 38% of cHL, but only in 7% of NLPHL. The number of patients receiving radiotherapy has been significantly reduced during the period studied. The relapse rate in cHL was 10 ± 2% and in NLPHL 16 ± 7%. The relapse rate was significantly higher in cHL stage IIB compared to other stages in the same therapy group. In cHL 6% died, and in NLPHL 0%. The 5-, 10- and 20-year overall survival estimates in cHL were 96 ± 1%, 95 ± 1% and 90 ± 3%, respectively, with no significant difference when comparing different treatment regimens and time periods. The 5- and 10-year overall survival after relapse in cHL was 81 ± 8% and 75 ± 10%, respectively. Conclusion. During the period studied there is no indication of a decline in survival despite changes in treatment. Survival rates in Sweden are high, and even after relapse chances of cure are high. We were not able to identify any characteristics specific for the group of patients that did not survive.

Abstract [en]

Hodgkin lymphoma (HL) is a heterogeneous condition varying from engaging one single lymph node site to a widespread condition. The prognosis with contemporary treatment is excellent for the vast majority. However, the treatment might cause severe late adverse effects in a proportion of the affected individuals.

We evaluated all children and adolescents diagnosed in Sweden and registered in the Swedish Childhood Cancer Register over a period of 25 years. The incidence has been stable and the overall survival (OS) is very good, comparable to the best results in the world. Approximately ten percent encountered a relapse, but even after relapse the chances of survival were good. During the study period there were no detectable changes in survival estimates. The use of radiotherapy has decreased.

Epstein Barr virus (EBV) and numbers of eosinophils, mast cells and macrophages in the tumors were investigated in 98 cases. Young children were more likely to express EBV. In patients with advanced disease the mast cell and macrophage counts were higher and they also had more affected laboratory parameters. Patients with Nodular Lymphocyte Predominant Hodgkin Lymphoma did not express EBV in the tumor, had significantly lower numbers of eosinophils, mast cells and macrophages and less affected laboratory parameters compared to classical HL.

Outcome and clinical presentation were investigated in a cohort of children, adolescents and young adults in Sweden and Denmark and treatment in pediatric and adult departments was compared. OS and event-free survival (EFS) did not differ between the three age groups nor between pediatric and adult treatment. However, the Danish pediatric patients had lower EFS, which corresponded to less use of radiotherapy. Adolescents and young adults shared similar characteristics, while children presented differently with less advanced disease and male preponderance.

Hospitalization rates and outpatient visits after end of treatment were evaluated to see whether the excess need of resources described in the literature is evenly distributed among the survivors or whether it is limited to a smaller group. Most of the patients had a low burden of health care use and the relapsing patients were the main drivers of the excess need.
