Abstract Pancreatic neuroendocrine tumours are the tumours developed at the expense of pancreas and require a specific diagnostic assessment. The imaging assessment of a pancreatic neuroendocrine tumour is useful for diagnosis as well as for surgical/medical treatment. Recently, a number of advances have been made in the field of imaging pancreatic neuroendocrine tumours, in particular in functional imaging using radiolabelled somatostatin analogues. In this review, we approach diagnostic progress by focusing on the advances of recent years. Thus, the interest of conventional imaging (scanner, abdominal ultrasound, and magnetic resonance imaging), ultrasound endoscopy and the place of functional imaging mainly with radiolabelled… More >

Abstract Typical or atypical bronchial carcinoids are rare tumors. The management of localized forms is essentially based on surgery and their prognosis remains good. The treatment of metastatic forms remains difficult with a low level of evidence. New treatments are emerging (everolimus, Lutatherapy), however, their respective place in the therapeutic algorithm should be clarified. Access to expertise and clinical research via the RENATEN-TENpath network should be promoted.

Abstract Neuroendocrine tumors (NET) are rare and can occur in all parts of the digestive tract. They can be functional or non-functional. All patients presenting NET should be discussed for the surgical management within the RENATEN tumor board. For sporadic pancreatic NET, surgery is recommended for non-functional lesion >2 cm in size and/or associated with ductal dilatation. For non-aggressive tumor, parenchyma-sparing surgery should be preferred to avoid exocrine and endocrine pancreatic insufficiency. For small bowel NET, surgery must always be considered to avoid complications such as small bowel obstruction. Lymphadenectomy must include at least 8 noded. Surgery must avoid short bowel… More >

Abstract Pheochromocytoma and paraganglioma are tumors leading to increased morbidity and mortality. Over the last 20 years, several major advances allowed a better characterization of these tumors, either from an imaging or from a genetic viewpoint. This is especially the case for the hereditary characteristics of these tumors, as roughly 20 new genes have been identified. This is why the initial steps of the management of a pheochromocytoma and/or a paraganglioma now require a dedicated tertiary referral center. The aim of this review is to depict the diagnostic steps of these tumors, so as to allow the clinician to determine the… More >

Abstract Little is known about the epidemiology of digestive neuroendocrine tumours (NETs). NETs remain a rare cancer, representing 1% of all digestive cancers. In France, incidence rates are estimated to around 1.1/100,000 inhabitants in males and 0.9/100,000 in females. The incidence rates got increased over time, with probably more than 1,000 new cases per year in France. Because of their relatively good prognosis, NETs are the second more prevalent digestive cancer after colorectal cancer. Most digestive NETs are well-differentiated (WDNETs); poorly differentiated neuroendocrine carcinomas (PDNEC) account for less than 20% of the cases in most of the series. Among bowel-NETs, the… More >

Abstract The WHO classification of the tumors of endocrine organs, published in July 2017 and that of digestive tumors, released in July 2019, have introduced significant changes in the classification of gastro-entero-pancreatic neuroendocrine tumors (NETs), which was unchanged since 2010. The main change is a new category of well-differentiated neoplasms, NET G3, in addition to the two previous categories NET G1 and NET G2. The other changes are: 1) the cut-off in Ki-67 index between NET G1 and G2, now set at 3%, 2) the term used for mixed tumors: MiNEN (mixed neuroendocrine-non neuroendocrine neoplasm) instead of MANEC (mixed adenoneuroendocrine carcinoma).… More >

Abstract For a patient suffering from breast cancer, access to the initial treatment includes several steps like confirmation of an anatomopathological diagnosis, proposition and establishment of an individualized treatment plan, pretreatment assessments, and access to the technical platform. The accumulated duration of these intervals plays a role in the prognosis in the early stages of the disease. In addition, it is important to manage all the uncertainties, both diagnostic and prognostic, which will inevitably upset the patient’s psychological balance. Supported by literature, recommendations and more than 20 years of experience in a multidisciplinary centre, the authors propose the organization of an… More >
