RESUMO
BACKGROUND: Among adult survivors of childhood brain tumors in Germany, we assessed their educational level and examined potentially influencing factors. PATIENTS AND METHODS: A questionnaire was sent to 505 childhood brain tumor survivors listed in the German Childhood Cancer Registry. 203/505 (40.2%) patients with treatment and educational data were included in the analysis.Of the included brain tumor survivors 54.7% (111/203) were male, the median age was 11.0 (1-15) years at diagnosis and 22.0 (19-37) years at the time of the survey. 34.8% (95%-CI 25.1-44.5) of female and 34.9% (26.0-43.8) of male survivors achieved a high school diploma. Survivors who had received irradiation had less likely obtained a high school diploma compared to those without irradiation. However, this association was statistically not significant: for either craniospinal or tumor irradiation adjusted odds ratio was 0.54 (0.08-3.76); for those with a combination of craniospinal and tumor irradiation 0.51 (0.07-3.59). Participants aged 6-10 years at diagnosis achieved a higher educational level 2.24 (0.45-11.25) compared to younger patients. CONCLUSION: 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.

PURPOSE: Fertility impairment and recovery after haematopoietic stem cell transplantation (HSCT) have been reported in both sexes, but little is known about how they develop over time. Our aim was to describe the dynamics of fertility impairment and recovery after HSCT. METHODS: We retrieved treatment and fertility data for up to 12 years of 361 paediatric patients with malignant and non-malignant diseases from seven European centres. The patients had been treated with allogeneic HSCT between 2000 and 2005. RESULTS: Development of fertility impairment was observed in males (123/217, 56%) after a median time of 2.6 years (range 0.1-11.4) and in females (82/144, 57%) after 2.3 years (range 0.1-12.0) after HSCT. Different busulfan dosages had only a slight impact on the onset of fertility impairment (busulfan ≥ 16 mg/kg with a median time to fertility impairment of 2.9 vs. 3.9 years after busulfan <14 mg/kg). Recovery from fertility impairment was observed in 17 participants after a median time of 4.1 years (range 1-10.6) in females (10/144, 7%) and 2.0 years (range 1-6.3) in males (7/217, 3 %) after fertility impairment first appeared. CONCLUSIONS: In the light of the dynamics of fertility impairment and recovery in the HSCT patients reviewed, these patients should be counselled comprehensively regarding fertility preservation measures.

PURPOSE: Fertility impairment and recovery after chemo- and radiotherapy have been reported in both male and female childhood cancer survivors, but little is known about the dynamics. Our aim, therefore, was to describe the development of fertility impairment and possible recovery in childhood brain tumour survivors. METHODS: In this longitudinal study, we included 144 survivors, who were treated in two German paediatric oncology centres between 2000 and 2005. Fertility parameters were retrieved from medical records up to 12 years after diagnosis. RESULTS: Participants with age ≥13 years and formerly cranial irradiation ≥30 Gray (n = 23), including 83 % (n = 19) with craniospinal irradiation ≥30 Gray, had a higher median FSH concentration compared to 29 patients without chemoradiotherapy: 8.3 IU/l (IQR 6.5-11.2) versus 4.1 IU/l (IQR 3.2-5.1) 2 years after initial treatment; 8.9 IU/l (IQR 8.5-10.8) versus 4.2 IU/l (IQR 2.4-6.7) after 8 years; and 7.1 IU/l (IQR 6.7-7.7) versus 3.5 IU/l (IQR 2.8-4.2) after 10 years. Altogether, 11/65 women reported the occurrence of amenorrhoea 6.0 years (range 1-10) after diagnosis. Five of these women later developed a regular menstrual cycle without hormone replacement therapy. Patients' chance of recovery from fertility impairment was increased with time since diagnosis (p = 0.074). CONCLUSION: Signs of fertility impairment such as amenorrhoea and elevated FSH levels were observed at variable time points between 1 and 12 years after chemoradiotherapy. Decreasing FSH levels were observed 1-7 years after elevation and were interpreted either as an atrophy of the pituitary gland or as recovery from fertility impairment.
