OBJECTIVES: Ga-DOTATOC (Ga) positron emission tomography (PET)/computed tomography (CT) is recommended in the workup of pancreas neuroendocrine tumors (PanNETs); evidence suggests that F-FDG (F) PET/CT can also provide prognostic information. Aims of this study were to assess the role of combined Ga- and F-PET/CT in the evaluation of grade (G) 1-2 PanNETs and to test the correlation between F-PET/CT positivity and tumor grade. METHODS: Preoperative Ga- and F-PET/CT of 35 patients with surgically resected G1-2 PanNETs were evaluated...

PURPOSE: While pancreaticoduodenectomy (PD) has been extensively studied in adults, there are few data pertaining specifically to pediatric patients. We retrospectively analyzed PD-associated morbidity and mortality in pediatric patients. METHODS: Our analytic cohort included all consecutive patients ≤18years of age treated at our institution from 1993 to 2015 who underwent PD. Patient data (demographics, disease characteristics, surgical and adjuvant treatment, length of hospital stay, and postoperative course) were extracted from the medical records...

OBJECTIVES: In-111-DTPA-octreotide (OctreoScan) is still pivotal for neuroendocrine tumor imaging, despite the introduction of Ga-68-octreotide tracers. Low-dose computed tomography (LDCT) assists in the localization of SPECT findings but often results in uncertain interpretation. This retrospective study evaluates the impact of coregistration of In-111-DTPA-octreotide SPECT/LDCT with diagnostic CT on interpretation. METHODS: Thirty-five consecutive studies, in which coregistration was performed because of uncertain interpretation, were evaluated...

Gastrointestinal secretory tumors, or gastroenteropancreatic neuroendocrine tumors, encompass a wide array of endocrine cell tumors. The significance of these tumors lies in their ability to alter physiology through hormone production as we well as in their malignant potential. Functioning tumors may present earlier due to symptomatology; conversely, non-functioning tumors are often diagnosed late as they reach large sizes, causing symptoms secondary to local mass effect. Imaging aids in the diagnosis, staging, and prognosis and provides key information for presurgical planning...

Pancreatic neuroendocrine tumors (PNETs) are rare and represent a heterogeneous disease. PNET can be functioning or non-functioning with different clinical presentations and different prognosis based on WHO and pTNM classifications. The role of imaging includes the localization of small functioning tumor, differentiation of these tumors from adenocarcinoma, identification of signs of malignancy and evaluation of extent. PNETs have a broad spectrum of appearance. On CT and MRI, most of functioning PNETs are well defined small tumors with intense and homogeneous enhancement on arterial and portal phases...

BACKGROUND: Mitotic count in hematoxylin-eosin stained slides and Ki-67 index allow stratification of patients for prognosis and therapeutic decision making in pancreatic neuroendocrine tumors (PNETs). However, the utility of Ki-67 determination in cytological material and its association to PNET prognosis are under discussion. METHODS: We have retrospectively reviewed all cases of EUS-FNA cytology of pancreatic lesions performed in the Hospital Clínico San Carlos (Madrid) between 2006 and 2016...

Incidental gastric subepithelial tumor (SET) is frequently found during endoscopy. Although endoscopic ultrasonography (EUS) can provide useful information, its diagnostic accuracy varies. Most of the potentially malignant tumors observed on EUS are hypoechoic lesions. Therefore, we aimed to investigate the diagnostic accuracy of EUS for hypoechoic lesions located in the submucosa or proper muscle layer. We also evaluated various characteristics for potential associations with diagnostic accuracy.A retrospective review was conducted of the medical records of 99 patients who were diagnosed with gastric SET and who underwent EUS with pathologic confirmation between March 2008 and April 2015...

A tumor consisting of an adenocarcinoma component and a neuroendocrine carcinoma component, with each component accounting for at least 30% of the tumor, is defined as a mixed adenoneuroendocrine carcinoma (MANEC). We report a case of MANEC of the pancreas. A 63-year-old man presented with hyperglycemia and was referred to our hospital for further examination. Abdominal contrast-enhanced computed tomography (CT) revealed a mass of 2 cm in size in the pancreas head with portal vein narrowing. Fluorin-18 fluorodeoxyglucose-positron emission tomography (FDG-PET) CT revealed increased accumulation in the mass of the pancreas head...

BACKGROUND: Although gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, they comprise less than 1% of all gastrointestinal tumors. Neuroendocrine tumors (NET) of the gastro-enteropancreatic system are also rare, representing about 2% of all gastrointestinal neoplasms. Pancreatic localization of NET is extremely uncommon-these tumors are only 1-5% of all pancreatic cancers. CASE PRESENTATION: We describe an unusual case with triple tumor localization-a gastric tumor, a formation in the pancreas, which involves the retroperitoneal space, and a uterine leiomyoma...

Neuroendocrine tumors (NETs) are rare tumors, but the incidence is increasing with new diagnostics. A 37-year-old man was admitted to our hospital for an incidental 17-mm nodule in the tail of the pancreas. PET/CT shows indeterminate mass in the pancreatic tail with enhanced uptake of 68-Ga-dotatate. NET was suspected and laparoscopic distal pancreatectomy was performed. Pathologic examination revealed an accessory spleen with a heterotopic location. To the best of our knowledge, this is the first intrapancreatic accessory spleen (IPAS) case in which the positive 68-Ga-dotatate uptake reported in the literature...

BACKGROUND: The biological behavior of well-differentiated neuroendocrine tumors of the pancreas (PNETs) is difficult to predict. This study was designed to determine whether involvement of the main pancreatic duct (MPD) serves as a poor prognostic factor for PNETs. METHODS: The involvement of the MPD in PNETs was defined as ductal stenosis inside the tumor mass associated with distal MPDs more than twofold larger in diameter than the proximal ducts. We examined the correlation between MPD involvement and other clinicopathological parameters, including nodal metastasis and recurrence-free survival, in 101 patients treated consecutively at three referral centers in Japan...

Serous cystic neoplasms (SCNs) are benign cystic neoplasms that predominantly occur in the tail of the pancreas in elderly women. It is well known that patients with von Hippel-Lindau syndrome can develop SCNs and neuroendocrine tumors in the pancreas. However, our understanding on SCNs accompanying other pancreatic tumors (SCNAOPTs) is limited. We compared the clinicopathologic features of 15 surgically resected SCNAOPTs with 259 conventional SCNs. The prevalence of SCNAOPT was 5%. The SCNAOPTs were significantly smaller than conventional solitary SCNs, and they were more commonly observed in the head of the pancreas, while conventional solitary SCNs were more frequently noted in the body and tail...

OBJECTIVE: To estimate short and long-term morbidity after pancreatic surgery for multiple endocrine neoplasia type 1 (MEN1)-related nonfunctioning pancreatic neuroendocrine tumors (NF-pNETs). BACKGROUND: Fifty percent of the MEN1 patients harbor multiple NF-pNETs. The decision to proceed to NF-pNET surgery is a balance between the risk of disease progression versus the risk of surgery-related morbidity. Currently, there are insufficient data on the surgical complications after MEN1 NF-pNET surgery...

Carney complex (CNC) is a rare disease associated with multiple neoplasias, including a predisposition to pancreatic tumors; it is caused most frequently by the inactivation of the PRKAR1A gene, a regulator of the cyclic AMP (cAMP)-dependent kinase (PKA). The method used was to create null alleles of prkar1a in mouse cells expressing pdx1 (Δ-Prkar1a). We found that these mice developed endocrine or mixed endocrine/acinar cell carcinomas with 100% penetrance by the age of 4-5 months. Malignant behavior of the tumors was seen as evidenced by stromal invasion and metastasis to locoregional lymph nodes...
