Background: Non-functioning pituitary adenomas (NFAs) are slow growing tumours with reported 5-year recurrence rates following resection up to 51%. The time point that it is safe to stop surveillance imaging is not clearly defined.Aim: To clarify the time spectrum of recurrence in patients with NFAs offered solely surgery as primary treatment and to estimate the safe time to stop surveillance pituitary imaging.Methods: Case-note an...

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 ...
