Eine Untersuchung über Nachkommen und Eltern von Hirntumorpatienten. Das Ergebnis: Bei Gehirntumorpatienten hatten 2,1% der Eltern ebenso einen Zentralnervensystem-Tumor. Schlussfolgerung (Zitat):
These data show a familial risk for brain tumors among adults. Diese Daten zeigen ein familiäres Risiko von Gehirntumoren...
Primary glioblastomas and anaplastic astrocytoma in a glioma familyJ. clin. neuroscience 2006 May;13(4):497-501.

A 72-year-old man presented with a short duration of symptoms relating to a right fronto-parietal glioblastoma and a family history of children with brain tumours. Analysis of the patient's family tree revealed that out of seven children, he had a living son with anaplastic astrocytoma, a daughter who had died with a glioblastoma, and a son who had died with a histologically undiagnosed intrinsic brain tumour. One niece was also thought to have died from a brain tumour. All of the other affected family members had onset in their third or fourth decades. Tissue was only available from two of the affected individuals, precluding familial genetic analysis at this stage. There is no clinical evidence to support a diagnosis of a multiple cancer or neurocutaneous syndrome in this family. In view of what is known about the genetics of familial glioma, it is interesting to note the clinical evidence of both 'primary' glioblastoma and anaplastic astrocytoma in the same kindred.

We used the nationwide Swedish Family-Cancer Database to analyze the risk for nervous system tumors in offspring through parental and sibling probands. Among 0-68-year-old offspring, close to 11000 patients with a nervous system tumor were identified in years 1961 to 2000, among whom 199 had a parent diagnosed with a nervous system tumor. Brain tumors constituted 86% of all tumors, and astrocytoma was the main histological type, representing half of all cases. Standardized incidence ratios (SIRs) for familial risk were only increased for brain tumors of meningioma, astrocytoma, and hemangioblastoma histology. When parents were diagnosed with tumors of the same histology, the SIRs for offspring were 3.06, 2.19, and 165 for meningioma, astrocytoma, and hemangioblastoma, respectively. Among siblings, the SIRs were 4.41, 3.20, and 61. Age-specific analysis of familial astrocytoma revealed three distinct components, one < 10 years, the second approximately age 30 years, and the third at age >60 years. The kappa test was used to assess the likelihood of an identical histology in two family members. The occurrence of hemangioblastoma was completely determined among the siblings, and the kappa value was 1.00. Meningiomas were also moderately ordered among the siblings, but astrocytomas were less determined. Many syndromes are known in which nervous system tumors are manifestations, including hemangioblastoma, recognized as part of von Hippel-Lindau disease. Yet, it is likely that many brain astrocytoma, meningioma, and mixed families represent yet unknown heritable conditions.
