ABSTRACT: 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. However, some PNETs with a more fibrous content may have a more delayed enhancement that is best depicted on the delayed phase. Other PNETs can present as purely cystic, complex cystic and solid tumors and calcified tumors. Non-functioning PNETs are larger with less intense and more heterogeneous enhancement. Functional imaging is useful for disease staging, to detect disease recurrence or the primary but also to select patient candidate for peptide receptor radiometabolic treatment.

ABSTRACT: Neuroendocrine tumours require dedicated interventions to control their capacity to secrete hormones but also, antitumour growth strategies. Recommendations for early interventions in NET include the management of hormone-related symptoms and poorly differentiated neuroendocrine carcinomas. In contrast, prognostic heterogeneity is a key feature of well differentiated NET that complexified the antitumour strategy whatever the stage in this subgroup of tumour. In this review, timely therapeutic interventions to control hormone-related symptoms and tumour growth in GEP NET patients are discussed. The necessity of controlling hormone-related symptoms as the first step of any strategy affects also the tumour growth control strategy. In the absence of cure at the metastatic stage, progresses are expected in the recognition of well differentiated NET subgroups that display either excellent or poor prognosis.

ABSTRACT: AIM OF THE STUDY: Neuroendocrine tumours are highly vascular neoplasms known to overexpress vascular endothelial growth factor (VEGF) and its receptor. Bevacizumab, an inhibitor of VEGF, was assessed in combination with chemotherapy in pancreatic neuroendocrine tumour (P-NET). PATIENTS AND METHODS: BETTER was a multicentre, open-label, non-randomised, two-group phase II trial. Patients with progressive metastatic, well-differentiated P-NET received a minimum of 6 month treatment of bevacizumab at 7.5 mg/kg IV on d1 q3w with 5-FU at 400 mg/m2/day and streptozocin at 500 mg/m2/day IV from d1 to d5 every 42 days. The primary end-point was progression-free survival (PFS); secondary end-points were overall survival (OS), overall response rate, safety and quality of life. RESULTS: A total of 34 patients were included. Median age was 55 years, 65% of patients were men, 97% had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 and 97% had a Ki-67 proliferative index of <15%. After a maximum of 24 month follow-up per patient, the median PFS assessed by investigators was 23.7 months [95% confidence interval (CI): 13.1; not reached], 19 (56%) patients had a partial response and 15 (44%) had stable disease as best response. OS rate at 24 months was 88%. The most frequently reported grade 3-4 adverse events were hypertension (21% patients), abdominal pain (12%) and thromboembolic events (9%). CONCLUSION: Bevacizumab with 5-FU/streptozocin in the treatment of pancreatic NETs seems to be feasible with a PFS of 23.7 months, which deserves further attention. No unexpected toxicity was observed.

ABSTRACT: BACKGROUND: Lanreotide depot/autogel antitumor activity in intestinal/pancreatic neuroendocrine tumors (NETs) was demonstrated in the phase-3 CLARINET study (NCT00353496), based on significantly prolonged progression-free survival (PFS) versus placebo. METHODS: During CLARINET, patients with metastatic intestinal/pancreatic NETs received lanreotide depot/autogel 120 mg or placebo every 4 weeks for 96 weeks. Imaging data (response evaluation criteria in solid tumors [RECIST] v1.0, centrally reviewed) were re-evaluated in this post hoc analysis of tumor growth rate (TGR) in NETs. TGR (%/month) was calculated from two imaging scans during relevant periods: pre-treatment (TGR RESULTS: TGR CONCLUSIONS: TGR provides valuable information on tumor activity and prognosis in patients with metastatic intestinal/pancreatic NETs, and identifies early lanreotide depot/autogel antitumor activity.

5 Article Chromogranin A measurement in metastatic well-differentiated gastroenteropancreatic neuroendocrine carcinoma: screening for false positives and a prospective follow-up study. 2011

Vezzosi, Delphine / Walter, Thomas / Laplanche, Agnès / Raoul, Jean Luc / Dromain, Clarisse / Ruszniewski, Philippe / d'Herbomez, Michèle / Guigay, Joël / Mitry, Emmanuel / Cadiot, Guillaume / Leboulleux, Sophie / Lombard-Bohas, Catherine / Borson-Chazot, Françoise / Ducreux, Michel / Baudin, Eric. ·Institut Gustave Roussy, Villejuif - France. ·Int J Biol Markers · Pubmed #21574156.

ABSTRACT: BACKGROUND: Multiple causes of false-positive chromogranin A (CgA) measurement have been reported that may affect its impact as a surrogate marker of RECIST progression in well-differentiated gastroenteropancreatic neuroendocrine tumors (WDGEPNET). ? AIMS: 1) To evaluate the frequency of false-positive CgA results. 2) To prospectively compare CgA variations with RECIST morphological changes in patients without known causes of false-positive CgA measurements.? METHODS: First, the conditions responsible for potentially false-positive CgA measurements were screened in 184 consecutive patients with metastatic WDGEPNET. Secondly, a variation in CgA at a 6-month interval was compared to RECIST results at 6 months in 46 patients.? RESULTS: Among 184 patients, elevated CgA was found in 130 cases (71%) including 99 patients with at least one cause of a false-positive result. Impaired kidney function as well as medication with proton pump inhibitors were found to be the 2 major causes of false-positive results. The sensitivity and specificity of CgA measurements compared with morphological tumor changes according to the RECIST criteria were 71% and 50%, respectively, at 6 months.? CONCLUSION: Routine screening for the causes of false-positive CgA measurements is mandatory in WDGEPNET patients. Our study does not validate the use of CgA as a surrogate marker of tumor progression.

6 Article Endocrine pancreatic tumours: which are the most useful MRI sequences? 2010

Caramella, C / Dromain, C / De Baere, T / Boulet, B / Schlumberger, M / Ducreux, M / Baudin, E. ·Department of Radiology, Institut Gustave-Roussy, 39, rue Camille Desmoulins, 94805, Villejuif Cedex, France. ·Eur Radiol · Pubmed #20668861.

ABSTRACT: OBJECTIVES: To determine magnetic resonance imaging (MRI) signal and enhancement characteristics of endocrine pancreatic tumours (ETPs) and which MR sequences show them most consistently. METHODS: Fifty-five consecutive patients with 68 ETPs underwent 1.5-T abdominal MRI comprising T2-weighted, unenhanced T1-weighted and dynamic T1-weighted after injection of gadopentetate dimeglumine sequences. Twenty-one patients underwent diffusion-weighted imaging (DWI). Two radiologists identified the number, location, size, signal and enhancement patterns of ETPs, and determined a confidence scale indicating the presence of tumours on DWI. The results were compared with echo-endoscopy (endoscopic ultrasound) findings. RESULTS: The detection sensitivity was 95%, similar to that of echo-endoscopy. T2-weighted and T1-weighted sequences at the arterial phase had the highest contrast-to-noise ratio (CNR) median value. On DWI, the mean sensitivity was 65%. The mean apparent diffusion coefficient (ADC) value of ETP was significantly lower than in the normal parenchyma. CONCLUSION: In suspected ETP, MRI is a sensitive method, similar to echo-endoscopy and could be recommended as the first imaging technique. T2-weighted sequences and T1-weighted sequences in the arterial phase are the optimal pulse sequences. The quantitative assessment of ADC values is a promising tool for the characterisation of pancreatic lesions.
