Children and adolescents with pre-existing conditions such as DNA repair defects
or other primary immunodeficiencies have an increased risk of non-Hodgkin
lymphoma. However, large-scale data on patients with non-Hodgkin lymphoma and
their entire spectrum of pre-existing conditions are scarce. A retrospective
multinational study was conducted by means of questionnaires sent out to the
national study groups or centers, by the two largest consortia in childhood
non-Hodgkin lymphoma, the European Intergroup for Childhood non-Hodgkin Lymphoma,
and the international Berlin-Frankfurt-Münster Study Group. The study identified
213 patients with non-Hodgkin lymphoma and a pre-existing condition. Four
subcategories were established: a) cancer predisposition syndromes (n=124, 58%);
b) primary immunodeficiencies not further specified (n=27, 13%); c) genetic
diseases with no increased cancer risk (n=40, 19%); and d) non-classifiable
conditions (n=22, 10%). Seventy-nine of 124 (64%) cancer predispositions were
reported in groups with more than 20 patients: ataxia telangiectasia (n=32),
Nijmegen breakage syndrome (n=26), constitutional mismatch repair deficiency
(n=21). For the 151 patients with a known cancer risk, 5-year event-free survival
and overall survival rates were 40%±4% and 51%±4%, respectively. Five-year
cumulative incidences of progression/relapse and treatment-related death as a
first event were 22%±4% and 24%±4%, respectively. Ten-year incidence of second
malignancy was 24%±5% and 7-year overall survival of the 21 patients with a
second malignancy was 41%±11%. Patients with non-Hodgkin lymphoma and
pre-existing conditions have an inferior survival rate with a large proportion of
therapy-related deaths compared to patients with non-Hodgkin lymphoma and no
pre-existing conditions. They may require special vigilance when receiving
standard or modified/reduced-intensity chemotherapy or when undergoing allogeneic
stem cell transplantation.
