Identification of molecular targets of Sunitinib in pancreatic neuroendocrine tumours

Bresciani Giulia , Gagliano Teresa , Hofland Leo J , Gentilin Erica , Falletta Simona , Riva Eleonora , Chiara Zatelli Maria

: Pancreatic neuroendocrine tumours (pNETs) are rare neoplasms arising from the endocrine pancreas. The fist line treatment is surgery that is often not curative in the presence of metastatic disease. Therefore, there is an increasing need for medical therapy. Sunitinib is a multi-target receptor tyrosine-kinase (RTK) inhibitor, described as having as main target VEGF receptor, with antitumor and antiangiogenic effects, approved for pNETs medical treatment. This study is aimed...

Study of different in vitro systems for the evalutation of Sunitinib effects in pancreatic neuroendocrine tumour cells

Bresciani Giulia , Gagliano Teresa , Hofland Leo J , Gentilin Erica , Falletta Simona , Riva Eleonora , Chiara Zatelli Maria

Finding new preclinical models to study the effects of anticancer drugs is one of the aims of biomedical research. Indeed, testing different in vitro systems can lead to a better understanding of the molecular pathways regulating tumor development and growth, and help to find new therapeutic approaches. This is crucial especially in the settings of pancreatic neuroendocrine tumours (pNET), where one of the main drugs approved for medical treatment is Sunitinib, a mult...

Von Hippel–Lindau syndrome: in vivo portrait with 68Ga-DOTANOC PET-CT

Paula Moreira Ana , Costa Gracinda , Pedroso de Lima Joao

Introduction: Von Hippel–Lindau syndrome (VHL) is an autosomal dominantly inherited neoplastic disorder with marked phenotypic variability, characterized by a broad spectrum of clinical manifestations in central nervous system (CNS) and viscera. Specific gene mutation can be demonstrated; however imaging plays an important role in diagnosis. 68Ga-labelled somatostatin analog (68Ga-DOTANOC) PET-CT is routinely employed for somatostatin receptor (SSTR) imaging, mainly for n...

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs): clinico-pathological characteristics and disease outcome of 110 patients treated at single referral medical center

Koren Shlomit , Or Karen , Steinschneider Miri , Kummer Esther , Yarom Nirit , Shirin Haim , Lavy Ron , Gratiana Gratiana , Benbassat Carlos

Introduction: GEP-NETs incidence increased markedly over the past decades probably due to increased imaging. GEP-NETs are generally indolent but often have unpredictable biological behavior and aggressive clinical course.Aims: To collect information regarding demographics, presentation, pathology characteristics, treatment and outcome of GEP-NETs.Methods: Following approval of our institutional ethical board, pathology and clinical...

Insulinoma: diagnostic features and treatment management

Khacimova Liana , Karonova Tatiana , Tsoy Uliana , Ianevskaia Liubov , Grineva Elena

Backgraund: Insulinoma is the most common functional pancreatic neuroendocrine tumor originating from β-cells, with unregulated insulin production and rarely associated with MEN-I syndrome. Diagnosis and treatment of insulinoma are a challenge in the practice of endocrinologist.Aim: To determine on the basis of retrospective analysis the optimal approaches to the management of patients with organic hyperinsulinism.Materials an...

A rare case: non-islet cell tumor hypoglycemia with adrenal insufficiency

Asoglu Veysi , Celik Mehmet , Bulbul Buket Yilmaz , Ayturk Semra , Ustun Funda , Guldiken Sibel

Non-islet cell tumor hypoglycemia (NICTH) is a rare paraneoplastic syndrome and is the second most common cause of tumor-related hypoglycemia following insulinoma. Its prevalence is not known and is likely that many cases would go undiagnosed. In here, we describe a patient with PNET who presented with severe hypoglycemia.A 37-year-old male with known metastatic Pancreatic neuroendocrine tumors (PNET) presented with weight loss, sweating, and tremor, epi...

Late manifestation of a mixed adenoneuroendocrine carcinoma of the cecum

Kazakou Paraskevi , Tzamali Xakousti , Travlos Alexis , Vogiatzi Evangelia , Ntali Georgia , Sarantopoulou Vasiliki , Polymeris Antonis

Introduction: Mixed adenoneuroendocrine carcinoma (MANEC) is a rare tumor of the gastrointestinal tract that consists of a dual adenocarcinomatous and neuroendocrine differentiation. The clinical behavior seems to be influenced by the neuroendocrine component. We report a patient with mixed adenoneuroendocrine carcinoma of cecum who presented 18 years after her initial diagnosis and treatment.Case report: A 59-year-old woman presented with a 3-month hist...

Quality of life in patients with neuroendocrine tumors treated with 177Lu-[DOTA0,Tyr3]-octreotate: a Single Tertiary Care Portuguese Center Experience

Lages Adriana , Moreira Helder , Costa Gracinda , Oliveira Patricia , Oliveira Diana , Martins Diana , Ventura Mara , Cunha Nelson , Carrilho Francisco

Introduction and purpose: 177Lu-[DOTA0,Tyr3]octreotate (177Lu-DOTA-TATE) is a radiopharmaceutical frequently used in peptide receptor radionuclide therapy (PRRT), which is a promising treatment modality in patients with metastasized neuroendocrine tumors (NETs). We purpose to evaluate the quality of life (QoL) in patients with somatostatin receptor positive inoperable or metastatic NETs throughout the three cycle’s (with three months intervals) proto...

Triple tumors in a patient with insulinoma

Ksela Urska , Krajnc Mitja

Introduction: Hypoglycemia is a rare clinical problem in patients not being treated for diabetes mellitus and requires further evaluation and management if Whipple’s triad is present. Insulinoma commonly presents with fasting hypoglycemia. Insulinoma is rarely associated with type 1 multiple endocrine neoplasia, when tumors are usually multiple and more frequently malignant. The diagnosis of insulinoma is established by demonstrating inappropriately high serum insulin con...
