Abstract

The elemental regional distribution in human brain tissue was obtained using PIXE analysis. A histo-pathological investigation was used to classify the samples into three different groups: (1) normal tissue, (2) tumour front and (3) tumour centre. Significant differences between the mean values of phosphorous, calcium, iron, zinc and selenium concentrations in each group are reported.

    In contrast, nickel concentrations do not significantly change between glioblastoma (grade IV) and healthy brains [145,146]. Iron and chromium are significantly increased in astrocytoma (III) and glioblastoma (IV) tumors compared to normal adjacent tissue [147,148], but the higher the malignancy grade between astrocytoma (I-III) and GBM (IV), the lower are the iron and cadmium concentrations [149,150]. Distribution of trace metals within individual tumors has also been examined, although studies of tumor tissue distribution was frequently limited by lack of direct within patient tumor-to-normal comparisons, relying instead on comparisons of tumor samples to brain samples from other age-matched individuals [145,149]; Nevertheless, changes in distribution of trace elements have been observed, with lead, zinc, calcium, and uranium showing homogeneous tumor distribution, while copper and iron are heterogeneously distributed [151,152].
