- Nuclear medicine has a central role in the diagnosis, staging, response assessment and long-term follow-up of neuroblastoma, the most common solid extracranial tumour in children. These EANM guidelines include updated information on I-123-mIBG, the most common study in nuclear medicine for the evaluation of neuroblastoma, and on PET/CT imaging with F-18-FDG, F-18-DOPA and Ga-68-DOTA peptides. These PET/CT studies are increasingly employed in clinical practice. Indications, advantages and limitations are presented along with recommendations on study protocols, interpretation of findings and reporting results.

- surgery (i.e. resection or liver transplantation), but only 10-20% of patients are candidates for this. In other patients, a variety of palliative treatments can be given, such as chemoembolization, radiofrequency ablation or recentlyPrimary liver cancers (i.e. hepatocellular carcinoma or cholangiocarcinoma) are worldwide some of the most frequent cancers, with rapidly fatal liver failure in a large majority of patients. Curative therapy consists of introduced tyrosine kinase inhibitors, e. g. sorafenib. Colorectal cancer is the second most lethal cancer in Europe and liver metastases are prevalent either at diagnosis or in follow-up. These patients are usually treated by a sequence of surgery, chemotherapy and antibody therapy [Okuda et al. (Cancer 56: 918-928, 1985); Schafer and Sorrell (Lancet 353: 1253-1257, 1999); Leong et al. (Arnold, London, 1999)]. Radioembolization is an innovative therapeutic approach defined as the injection of micron-sized embolic particles loaded with a radioisotope by use of percutaneous intra-arterial techniques. Advantages of the use of these intra-arterial radioactive compounds are the ability to deliver high doses of radiation to small target volumes, the relatively low toxicity profile, the possibility to treat the whole liver including microscopic disease and the feasibility of combination with other therapy modalities. Disadvantages are mainly due to radioprotection constraints mainly for I-131-labelled agents, logistics and the possibility of inadvertent delivery or shunting [Novell et al. (Br J Surg 78: 901-906, 1991)]. The Therapy, Oncology and Dosimetry Committees have worked together in order to revise the European Association of Nuclear Medicine (EANM) guidelines on the use of the radiopharmaceutical I-131-Lipiodol (Lipiocis (R), IBA, Brussels, Belgium) and include the newer medical devices with Y-90-microspheres. Y-90 is either bound to resin (SIR-Spheres (R), Sirtex Medical, Lane Cove, Australia) or embedded in a glass matrix (TheraSphere (R), MDS Nordion, Kanata, ON, Canada). Since Y-90-microspheres are not metabolized, they are not registered as unsealed sources. However, the microspheres are delivered in aqueous solution: radioactive contamination is a concern and microspheres should be handled, like other radiopharmaceuticals, as open sources. The purpose of this guideline is to assist the nuclear medicine physician in treating and managing patients undergoing such treatment. I-131-Lipiodol is a consolidated treatment option and the previous European Association of Nuclear Medicine (EANM) guidelines have been revised for its use. The newer Y-90-microsphere therapy is rapidly expanding throughout the nuclear medicine community. To date, published data on microspheres, particularly on dosimetry features and the characterization of the objective response, are still preliminary. Therefore, the aim of this part of the document is to set up a first basic procedure to guide nuclear medicine physicians in treatment with radiolabelled microspheres.

- Introduction Malignant pheochromocytomas (PCCs) and paragangliomas (PGLs) are rare disorders arising from the adrenal gland, from the glomera along parasympathetic nerves or from paraganglia along the sympathetic trunk. According to the WHO classification, malignancy of PCCs and PGLs is defined by the presence of metastases at non-chromaffin sites distant from that of the primary tumor and not by local invasion. The overall prognosis of metastasized PCCs/PGLs is poor. Surgery offers currently the only change of cure. Preferably, the discrimination between malignant and benign PCCs/PGLs should be made preoperatively. less thanbrgreater than less thanbrgreater thanMethods This review summarizes our current knowledge on how benign and malignant tumors can be distinguished. less thanbrgreater than less thanbrgreater thanConclusion Due to the rarity of malignant PCCs/PGLs and the obvious difficulties in distinguishing benign and malignant PCCs/PGLs, any patient with a PCC/PGL should be treated in a specialized center where a multidisciplinary setting with specialized teams consisting of radiologists, endocrinologist, oncologists, pathologists and surgeons is available. This would also facilitate future studies to address the existing diagnostic and/or therapeutic obstacles.

- Purpose To assess the impact of baseline liver tumour burden, alkaline phosphatase (ALP) elevation, and target lesion size on treatment outcomes with Lu-177-Dotatate. Methods In the phase 3 NETTER-1 trial, patients with advanced, progressive midgut neuroendocrine tumours (NET) were randomised to 177Lu-Dotatate (every 8 weeks, four cycles) plus octreotide long-acting release (LAR) or to octreotide LAR 60 mg. Primary endpoint was progression-free survival (PFS). Analyses of PFS by baseline factors, including liver tumour burden, ALP elevation, and target lesion size, were performed using Kaplan-Meier estimates; hazard ratios (HRs) with corresponding 95% CIs were estimated using Cox regression. Results Significantly prolonged median PFS occurred with Lu-177-Dotatate versus octreotide LAR 60 mg in patients with low (< 25%), moderate (25-50%), and high (> 50%) liver tumour burden (HR 0.187, 0.216, 0.145), and normal or elevated ALP (HR 0.153, 0.177), and in the presence or absence of a large target lesion (diameter > 30 mm; HR, 0.213, 0.063). Within the Lu-177-Dotatate arm, no significant difference in PFS was observed amongst patients with low/moderate/high liver tumour burden (P = 0.7225) or with normal/elevated baseline ALP (P = 0.3532), but absence of a large target lesion was associated with improved PFS (P = 0.0222). Grade 3 and 4 liver function abnormalities were rare and did not appear to be associated with high baseline liver tumour burden. Conclusions Lu-177-Dotatate demonstrated significant prolongation in PFS versus high-dose octreotide LAR in patients with advanced, progressive midgut NET, regardless of baseline liver tumour burden, elevated ALP, or the presence of a large target lesion. : NCT01578239, EudraCT: 2011-005049-11

- Contrast-enhanced computed tomography (CT) of the neckthorax-abdomen and pelvis, including 3-phase examination of the liver, constitutes the basic imaging for primary neuroendocrine tumor (NET) diagnosis, staging, surveillance, and therapy monitoring. CT characterization of lymph nodes is difficult because of inadequate size criteria (short axis diameter), and bone metastases are often missed. Contrast-enhanced magnetic resonance imaging (MRI) including diffusion-weighted imaging is preferred for the examination of the liver, pancreas, brain and bone. MRI may miss small lung metastases. MRI is less well suited than CT for the examination of extended body areas because of the longer examination procedure. Ultrasonography (US) frequently provides the initial diagnosis of liver metastases and contrast-enhanced US is excellent to characterize liver lesions that remain equivocal on CT/MRI. US is the method of choice to guide the biopsy needle for the histopathological NET diagnosis. US cannot visualize thoracic NET lesions for which CTguided biopsy therefore is used. Endocopic US is the most sensitive method to diagnose pancreatic NETs, and additionally allows for biopsy. Intraoperative US facilitates lesion detection in the pancreas and liver. Somatostatin receptor imaging should be a part of the tumor staging, preoperative imaging and restaging, for which 68 Ga-DOTA-somatostatin analog PET/CT is recommended, which is vastly superior to somatostatin receptor scintigraphy, and facilitates the diagnosis of most types of NET lesions, for example lymph node metastases, bone metastases, liver metastases, peritoneal lesions, and primary small intestinal NETs. (18)FDG-PET/CT is better suited for G3 and high G2 NETs, which generally have higher glucose metabolism and less somatostatin receptor expression than low-grade NETs, and additionally provides prognostic information.

Tidskriftsartikel (refereegranskat)abstract
- Background In January 2004, EMEA approved Y-90-radiolabelled ibritumomab tiuxetan, Zevalin, in Europe for the treatment of adult patients with rituximab-relapsed or -refractory CD20+ follicular B-cell non-Hodgkin's lymphoma. The number of European nuclear medicine departments using Zevalin is continuously increasing, since the therapy is often considered successful. The Therapy, Oncology and Dosimetry Committees have worked together in order to define some EANM guidelines on the use of Zevalin, paying particular attention to the problems related to nuclear medicine. Purpose The purpose of this guideline is to assist the nuclear medicine physician in treating and managing patients who may be candidates for radio-immunotherapy. The guideline also stresses the need for close collaboration with the physician(s) treating the patient for the underlying disease.
