Mass Spectrometry Imaging Identifies Metabolic Patterns Associated with Malignant Potential in Pheochromocytoma and Paraganglioma.

Eur J Endocrinol 2021 May 1. Epub 2021 May 1.

F Beuschlein, Klinik für Endokrinologie, Diabetologie und Klinische Ernährung, UniversitatsSpital Zurich, Zurich, 8091, Switzerland.

Objective: Within the past decade, important genetic drivers of pheochromocytoma and paraganglioma (PPGLs) development have been identified. The pathophysiological mechanism that translate these alterations into functional autonomy and potentially malignant behavior have not been elucidated in detail. Here we used MALDI-mass spectrometry imaging (MALDI-MSI) of formalin-fixed paraffin-embedded tissue specimens to comprehensively characterize the metabolic profiles of PPGLs. Read More

Department of Urology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.

Pheochromocytoma (PHEO) is a rare neuroendocrine that tumor originated from the adrenal medulla that secrets catecholamines. Tumors from extra-adrenal chromaffin tissues are called extra-adrenal PHEO or paraganglioma (PGL). To our knowledge, adrenal PHEO and subclinical PGL with inferior vena cava (IVC) invasion had been sporadically reported, while functional PGL with IVC tumor thrombus has not been publicly reported yet.

Multidisciplinary practice guidelines for the diagnosis, genetic counseling and treatment of pheochromocytomas and paragangliomas.

Clin Transl Oncol 2021 May 6. Epub 2021 May 6.

Endocrinology and Nutrition Department, Hospital Clinic Barcelona, University of Barcelona, IDIBAPS, Barcelona, Spain.

Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumors that arise from chromaffin cells of the adrenal medulla and the sympathetic/parasympathetic neural ganglia, respectively. The heterogeneity in its etiology makes PPGL diagnosis and treatment very complex. The aim of this article was to provide practical clinical guidelines for the diagnosis and treatment of PPGLs from a multidisciplinary perspective, with the involvement of the Spanish Societies of Endocrinology and Nutrition (SEEN), Medical Oncology (SEOM), Medical Radiology (SERAM), Nuclear Medicine and Molecular Imaging (SEMNIM), Otorhinolaryngology (SEORL), Pathology (SEAP), Radiation Oncology (SEOR), Surgery (AEC) and the Spanish National Cancer Research Center (CNIO).

Retroperitoneal liposarcoma mimicking pheochromocytoma.

Radiol Case Rep 2021 Jun 15;16(6):1493-1498. Epub 2021 Apr 15.

Department of Clinical Surgical Sciences, The University of the West Indies, St Augustine Campus, Trinidad, West Indies.

Retroperitoneal liposarcomas are rare mesenchymal tumors which carry a poor prognosis because of their late presentation. When symptoms do occur, they are usually nonspecific and related to mass effect or invasion of local structures. Rarely, retroperitoneal liposarcomas can clinically and biochemically mimic phaeochromocytomas. Read More

Colonic Pseudo-obstruction as a Rare Complication of Pheochromocytoma.

Eur J Case Rep Intern Med 2021 26;8(3):002421. Epub 2021 Mar 26.

Department of Radiology and Organ Imaging, United Christian Hospital, Hong Kong.

Colonic pseudo-obstruction is characterized by dilatation of the colon without a structural lesion causing the obstruction. It usually involves the caecum and right side of the colon and is commonly observed in patients with severe illness or after surgery; it is rarely caused by pheochromocytoma. The diagnosis of colonic pseudo-obstruction can be established by abdominal imaging including computed tomography (CT) of the abdomen or use of a water-soluble contrast enema. Read More

Somatostatin Receptors and Analogs in Pheochromocytoma and Paraganglioma: Old Players in a New Precision Medicine World.

Front Endocrinol (Lausanne) 2021 29;12:625312. Epub 2021 Mar 29.

Section on Medical Neuroendocrinology, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD, United States.

Neuroendocrine tumors overexpress somatostatin receptors, which serve as important and unique therapeutic targets for well-differentiated advanced disease. This overexpression is a well-established finding in gastroenteropancreatic neuroendocrine tumors which has guided new medical therapies in the administration of somatostatin analogs, both "cold", particularly octreotide and lanreotide, and "hot" analogs, chelated to radiolabeled isotopes. The binding of these analogs to somatostatin receptors effectively suppresses excess hormone secretion and tumor cell proliferation, leading to stabilization, and in some cases, tumor shrinkage.

Reducing failures in daily medical practice: Healthcare failure mode and effect analysis combined with computer simulation.

Ergonomics 2021 May 3:1-11. Epub 2021 May 3.

Department of Endocrine Oncology, University Medical Center Utrecht, Utrecht, The Netherlands.

This study proposes a risk analysis approach for complex healthcare processes that combines qualitative and quantitative methods to improve patient safety. We combine Healthcare Failure Mode and Effect Analysis with Computer Simulation (HFMEA-CS), to overcome widely recognised HFMEA drawbacks regarding the reproducibility and validity of the outcomes due to human interpretation, and show the application of this methodology in a complex healthcare setting. HFMEA-CS is applied to analyse drug adherence performance in the surgical admission to discharge process of pheochromocytoma patients. Read More

Misleading GALLIUM-dotatate PET scan in a patient with a history of a phaeochromocytoma: Unsuspected uptake in papillary thyroid carcinoma metastases.

J Neuroendocrinol 2021 Mar 23:e12964. Epub 2021 Mar 23.

ENETs Centre of Excellence, Royal Free Hospital, London, UK.

Scanning for somatostatin receptors using Ga-dotatate positron emission tomography with co-registration with computed tomography or magnetic resonance imaging is now in widespread use for the identification of neuroendocrine tumours, phaeochromocytomas, and paragangliomas and their metastases. We present a case where a patient with a phaeochromocytoma showed uptake in her neck considered diagnostic of a head-and-neck paraganglioma, which was subsequently confirmed to be a metastatic papillary thyroid carcinoma. We alert clinicians to such falsely-identified tumours using this extensively used imaging technique. Read More

Advances in the automated synthesis of 6-[F]Fluoro-L-DOPA.

EJNMMI Radiopharm Chem 2021 Mar 10;6(1):11. Epub 2021 Mar 10.

ICNAS/CIBIT - Institute for Nuclear Sciences Applied to Health, University of Coimbra, Pólo das Ciências da Saúde, Azinhaga de Santa Comba, 3000-548, Coimbra, Portugal.

The neurotracer 6-[18F] FDOPA has been, for many years, a powerful tool in PET imaging of neuropsychiatric diseases, movement disorders and brain malignancies. More recently, it also demonstrated good results in the diagnosis of other malignancies such as neuroendocrine tumours, pheochromocytoma or pancreatic adenocarcinoma.The multiple clinical applications of this tracer fostered a very strong interest in the development of new and improved methods for its radiosynthesis.
