Backgeound and Aims: Phaeochromocytomas (PCC) and paragangliomas (PGL) are mostly benign sympathoadrenal tumours. However, there are no available markers to predict a malignant course. Since hypoxia is involved in the pathogenesis of these tumours, we aimed to qualify the relevance of the mammalian Target of Rapamycin (m-TOR) and hypoxic pathways in benign and malignant PCC/PGL.Methods: Tissue microarray (TMA) blocks were constructed with 80 PCC/PGL, inc...

Background and Aims: Phaeochromocytoma and paragangliomas are neuroendocrine tumours arising from chromaffin cells. These tumours express somatostatin receptors (SSTRs), which has five different main subtypes (SSTR1, SSTR2, SSTR3, SSTR4 and SSTR5). The differential expression of the different receptor subtypes in these tumours has previously been reported with a small series of tumour samples. Our study examined the expression of SSTR subtypes in a larger series of benign and ...
