Therapeutic options in metastatic phaeochromocytomas

Mills Edouard , Dina Roberto , Palazzo Fausto , Sharma Rohini , Wernig Florian

Phaeochromocytomas are rare neuroendocrine tumours. Prediction of aggressive tumour behaviour remains a major challenge. We report a 68-year-old female who was found to have a locally arising colonic adenocarcinoma on biopsies. Staging also identified a 10.7 cm right adrenal lesion and work-up revealed markedly raised urinary metanephrines and positive MIBG imaging. The MDT decision was to first remove the colonic cancer with appropriate alpha blockade. It was felt that a comb...

The difficulty in predicting aggressive tumour behaviour of phaeochromocytomas

Mills Edouard , Naqvi Ali , Dina Roberto , Palazzo Fausto , Wernig Florian

Phaeochromocytoma and paragangliomas (PH/PG) are rare neuroendocrine tumours. Prediction of aggressive tumour behaviour remains a major challenge. The Phaeochromocytoma of the Adrenal gland Scaled Score (PASS) is used to separate benign from malignant lesions with a score > 4 showing potential for biologically aggressive behaviour. Pre-operatively, MIBG together with CT/MRI remain the diagnostic radiological gold standard.We report a 68-year-old fema...

Study of hsa-miR-30e miRNA as a biomarker in identifying multiple gland disease in sporadic primary hyperparathyroidism: Is it time for individualized molecular-based surgery?

Introduction: Sporadic primary hyperparathyroidism (sporadic PHPT) is a common endocrine disorder, usually caused by a single parathyroid adenoma. However, up to 15% of patients present with multiple gland disease (MGD), which cannot be always diagnosed preoperatively, raising serious management problems. No predictive genetic screening tests are currently available to distinguishing adenomas from MGD in sporadic PHPT. MiRNAs are widely established as genetic molecules that ha...

Role of the hypoxic signalling pathways in the histopathological prediction of malignancy in phaeochromocytomas and paragangliomas

Pinato David , Ramachandran Radha , Toloue Kalami Toussi Samin , Vergine Marco , Ngo Nyethane , Sharma Rohini , Khoo Bernard , Meeran Karim , Palazzo Fausto , Martin Niamh , Dina Roberto , Tan Tricia

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...

Expression of Somatostatin Receptors in Phaeochromocytoma and Paragangliomas

Parvizi Nassim , Alsafi Ali , Vergine Marco , Ramachandran Radha , Martin Niamh , Palazzo Fausto , Pinato David , Sharma Rohini , Meeran Karim , Dina Roberto , Tan Tricia

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 ...
