We present revised diagnostic and therapeutic guidelines for the management of pancreatic neuroendocrine neoplasms (PNENs) proposed by the Polish Network of Neuroendocrine Tumours. These guidelines refer to biochemical (determination of specific and nonspecific neuroendocrine markers) and imaging diagnostics (EUS, CT, MR, and radioisotope examination with a 68 Ga or 99Tc labelled somatostatin analogue). A histopathological diagnostic, which determines the further management of patients with PNENs, must be necessarily confirmed by immunohistochemical tests. PNENs therapy requires collaboration between a multidisciplinary team of specialists experienced in the management of these neoplasms. Surgery is the basic form of treatment. Medical therapy requires a multidirectional procedure, and therefore the rules of biotherapy, peptide receptor radionuclide therapy, chemotherapy and molecular targeted therapy are discussed.

“…In this implementation low-energy cancer tracers [3,5] are assumed since they require small and thus light collimators (for energies below ≈ 250 [keV ] only a couple of millimeters of lead are sufficient for shielding). Unfortunately this leaves out the possibility of using the system with several successful cancer tracers like F -18-FDG, due to their high-energy nature (energy above 400 [keV ], where some centimeters of lead are needed for effective shielding).…”

Abstract. Liver metastases are an advanced stage of several types of cancer, usually treated with surgery. Intra-operative localization of these lesions is currently facilitated by intra-operative ultrasound (IOUS) and palpation, yielding a high rate of false positives due to benign abnormal regions. In this paper we present the integration of functional nuclear information from a gamma probe with IOUS, to provide a synchronized, real-time visualization that facilitates the detection of active metastases intra-operatively. We evaluate the system in an ex-vivo setup employing a group of physicians and medical technicians and show that the addition of functional imaging improves the accuracy of localizing and identifying malignant and benign lesions significantly. Furthermore we are able to demonstrate that the inclusion of an advanced, augmented visualization provides more reliability and confidence on classifying these lesions in the presented evaluation setup. MotivationLiver metastases are a common consequence of cancer cells spreading from primary tumors. Surgical resection is the indicated therapy if possible, as it results in a cure with high probability [1]. To facilitate extraction, intra-operative localization of the tumorous regions is achieved by a combination of palpation and intra-operative ultrasound (IOUS). This technique is considered the gold standard as it has been in successful clinical practice for years already with a proved high sensitivity [2,3]. However, in the presence of benign abnormal structures, a considerable false-positive detection rate still remains. These abnormalities may be cysts, hemangiomas, scar tissue, or even metastases, which were previously diagnosed by e.g. PET/CT and treated successfully with chemotherapy or other neoadjuvant therapies [3]. This problem, although reduced, is still present when using contrast-enhanced ultrasound [2], which has a promising potential for better image quality, but still remains a mostly anatomical imaging modality.To reduce the detection rate of false-positives, the integration of a functional modality to complement the standard localization technique is a promising approach. A prime candidate for this is nuclear imaging, as there are tracers with
