ReviewCytokine patterns in patients with cancer: a systematic review.
Active, but dysfunctional, immune responses in patients with cancer have been studied in several tumour types, but owing to the heterogeneity of cancer theories of common reaction mechanisms seem to be obsolete. In this Review of published clinical studies of patients with cancer, expression and interplay of the following cytokines are examined: interleukin 2, interleukin 6, interleukin 8, interleukin 10, interleukin 12, interleukin 18, tumour necrosis factor α (TNFα), transforming growth factor β (TGFβ), interferon-γ, HLA-DR, macrophage migration inhibitory factor (MIF), and C-X-C motif chemokine receptor 4 (CXCR4). Clinical data were analysed in a non-quantitative descriptive manner and interpreted with regard to experimentally established physiological cytokine interactions. ⋯ Cytokines produced by tumours might have a pivotal role in this defect. A working hypothesis is that the cancer-specific and histology-independent uniform cytokine cascade is one of the manifestations of the underlying paraneoplastic systemic disease, and this hypothesis links the stage of cancer with both the functional status of the immune system and the patient's prognosis. Neutralisation of this cytokine pattern could offer novel and so far unexploited treatment approaches for cancer.

Multicenter StudyMethylation of the TERT promoter and risk stratification of childhood brain tumours: an integrative genomic and molecular study.
Identification of robust biomarkers of malignancy and methods to establish disease progression is a major goal in paediatric neuro-oncology. We investigated whether methylation of the TERT promoter can be a biomarker for malignancy and patient outcome in paediatric brain tumours. ⋯ The Canadian Institute of Health Research and the Terry Fox Foundation.
