To assess the level of graduation, the wish to have children and the course of pregnancy among former patients with childhood leukemia in comparison to the general German population and depending on gender, a nationwide survey was conducted in 2008. In total 63.6% (1476/2319) of the contacted survivors of childhood leukemia participated (mean age 25.7 years, range 19-43 years). Survivors graduated at higher levels of school compared to the general population, with 48.6% (female) versus 38.0% and 52.6% (male) versus 35.8% (p < 0.001). Also, 93.3% of female and 89.3% of male survivors indicated a similar general wish to have children compared to the general population. Survivors reported parenthood less frequently compared to the general population (p < 0.001). The course of pregnancy in survivors was characterized by fewer abortions (p < 0.001). Having leukemia in childhood and adolescence impairs the likelihood of becoming a parent but reduces neither the wish to have children nor the level of graduation.
A third of the childhood brain tumor survivors who participated in our survey obtained the highest school leaving certificate. This may be biased by an overrepresentation of well-educated survivors without major cancer-related late effects. The influence of the patients' strong motivation following a severe illness combined with the intensive psychosocial and/or pedagogical support on education needs to be examined in future studies.
As survival rates of patients with childhood brain tumors have increased to 75%, treatment related side effects are of particular importance. The present study evaluated questionnaire-based fertility characteristics in cancer survivors treated with irradiation to the hypo-thalamic-pituitary-axis.A nationwide survey was conducted in collaboration with the German Childhood Cancer Registry. Questionnaire and treatment data could be retrieved for 1110 former childhood cancer patients with cranial irradiation and/or chemotherapy.Survivors receiving ≥30 gray vs. 18-29 gray and 0-17 gray to the pituitary gland reported less pregnancies or less with their partners (7.4% vs. 32.8% vs. 12.4%; p<0.001), were more often infertile (40% vs. 9.4% vs. 12.5%; p<0.001) and the female participants, had a higher frequency of permanent amenorrhea (16.7% vs. 1.7% vs. 0%; p<0.001).Irradiation of the pituitary gland ≥ 30 gray seemed to be associated with less pregnancies and increased permanent amenorrhea in women. Future studies need to be conducted to confirm these results. Increased knowledge of treatment related side effects might help brain tumor patients to improve their family planning if necessary by gonadotropine replacement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
