1 Clinical Trial Ki-67 grading of nonfunctioning pancreatic neuroendocrine tumors on histologic samples obtained by EUS-guided fine-needle tissue acquisition: a prospective study. 2012

ABSTRACT: BACKGROUND: Preoperative determination of Ki-67 expression, an important prognostic factor for grading nonfunctioning pancreatic endocrine tumors (NF-PETs), remains an important clinical challenge. OBJECTIVE: To prospectively evaluate the feasibility, yield, and clinical impact of EUS-guided fine-needle tissue acquisition (EUS-FNTA) with a large-gauge needle to obtain tissue samples for histologic diagnosis and Ki-67 analysis in patients with suspected NF-PETs. DESIGN: Prospective cohort study. SETTING: Tertiary-care academic medical center. PATIENTS: Consecutive patients with a single pancreatic lesion suspicious for NF-PET on imaging. INTERVENTION: EUS-FNTA with a 19-gauge needle. MAIN OUTCOME MEASUREMENTS: Feasibility and yield of EUS-FNTA for diagnosis and Ki-67 expression determination. RESULTS: Thirty patients (mean [± SD] age 55.7 ± 14.9 years), with a mean (± SD) lesion size of 16.9 ± 6.1 mm were enrolled. EUS-FNTA was successfully performed without complications in all patients, with a mean (± SD) of 2.7 ± 0.5 passes per patient. Adequate samples for histologic examination were obtained in 28 of the 30 patients (93.3%). Ki-67 determination could be performed in 26 of these 28 patients (92.9%, 86.6% overall), 12 of whom underwent surgical resection. Preoperative and postoperative Ki-67 proliferation indexes were concordant in 10 patients (83.3%), whereas 2 patients were upstaged from G1 to G2 or downstaged from G2 to G1, respectively. LIMITATIONS: Single center study with a single operator. CONCLUSION: In patients with suspected nonfunctioning low-grade to intermediate-grade pancreatic neuroendocrine tumors (p-NETs), retrieval of tissue specimens with EUS-FNTA by using a 19-gauge needle is safe, feasible, and highly accurate for both diagnosis and Ki-67 determination. A Ki-67 proliferative index acquired through this technique might be of great help for further therapeutic decisions.

ABSTRACT: PURPOSE: Multiple endocrine neoplasia type 1 (MEN1) is an inherited endocrine neoplastic syndrome associated with a greater risk of endocrine tumor development like pancreatic neuroendocrine tumors (p-NET), with different clinical characteristics from sporadic ones. This paper aims to compare clinical, hystological and morphological aspects of p-NET in patients affected from MEN1 (MEN1+) and not-affected ones (MEN1-). METHODS: We performed a retrospective observational study. Data was collected between December 2010 and December 2015, including patients with a histological diagnosis of p-NET and radiological imaging. We compared clinical, histological, radiological, and prognostic aspects of MEN+ p-NET with MEN-1 p-NET. RESULTS: Of the 45 patients enrolled, 13 MEN1+ and 21 MEN1- cases were analyzed. Frequency of not secreting p-NETs and insulin secreting p-NETs, histopathological grades and Ki67 expression were superimposable between MEN1+ and MEN1- patients. MEN1+ pNETs are more often multicentric compared to MEN1- pNETs. Frequency of liver and nodes metastatic spread was higher in MEN1- p-NET compared to MEN1+ p-NET. Analyzing p-NET according to the disease outcome, we found that recovered and stable p-NETs in MEN1+ patients, compared to MEN1- cases, are diagnosed at lower age (p = 0.04/p = 0.002) and that are more frequently multifocal lesions (p = 0.009/p = 0.002). CONCLUSIONS: In our study pNETs in MEN1+ and pNETs in MEN1- don't significantly differ for prognosis but only for clinical features. p-NET stage disease and prognosis can be positively influenced by early diagnosis and screening in index patients' first-degree relatives.

3 Article Evaluation of the Added Value of Diffusion-Weighted Imaging to Conventional Magnetic Resonance Imaging in Pancreatic Neuroendocrine Tumors and Comparison With 68Ga-DOTANOC Positron Emission Tomography/Computed Tomography. 2016

ABSTRACT: OBJECTIVES: The aims of this study were to investigate the added value of diffusion-weighted imaging (DWI) in pancreatic neuroendocrine tumor (pNET) evaluation and to compare magnetic resonance imaging (MRI) to Ga-DOTANOC positron emission tomography/computed tomography (PET/CT) results. METHODS: Morphological MRI (T2-weighted [T2-w] + contrast-enhanced [CE] T1-w) and DWI (T2-w + DWI) and Ga-DOTANOC PET/CT in 25 patients/30 pNETs were retrospectively evaluated. Per-patient and per-lesion detection rates (pDR and lDR, respectively) were calculated. Apparent diffusion coefficient values were compared among pNET and surrounding and normal pancreas (control group, 18 patients). Apparent diffusion coefficient and standardized uptake value (SUV) values were compared among different grading and staging groups. RESULTS: No statistically significant differences in PET/CT and MRI session detection rates were found (morphological MRI and DW-MRI, 88% pDR and 87% lDR; combined evaluation, 92% pDR and 90% lDR; Ga-DOTANOC PET/CT, 88% pDR and 80% lDR). Consensus reading (morphological/DW-MRI + PET/CT) improved pDR and lDR (100%). Apparent diffusion coefficient mean value was significantly lower compared with surrounding and normal parenchyma (P < 0.01). The apparent diffusion coefficient and SUV values of pNETs among different grading and staging groups were not statistically different. CONCLUSIONS: Conventional MRI, DW-MRI + T2-w sequences, and Ga-DOTANOC PET/CT can be alternative tools in pNET detection. Diffusion-weighted MRI could be valuable in patients with clinical suspicion but negative conventional imaging findings. However, the consensus reading of the 3 techniques seems the best approach.
