4 Review Gastric and duodenal neuroendocrine tumours. 2012

O'Toole, Dermot / Delle Fave, Gianfranco / Jensen, Robert T. ·Department of Gastroenterology and Clinical Medicine, St James's Hospital and Trinity College, Dublin, Ireland. dermot.otoole@tcd.ie ·Best Pract Res Clin Gastroenterol · Pubmed #23582915.

ABSTRACT: Gastric neuroendocrine neoplasms (NENs) are increasing in frequency and have a varied spectrum with regard to histology, clinicopathologic background, stage, and prognosis. They are usually discovered incidentally, are for the most part benign and are associated with hypergastrinaemia (secondary either to chronic atrophic gastritis or rarely Zollinger-Ellison syndrome; types 1 and 2, respectively) or more rarely sporadic type 3. Applications of recent staging and grading systems - namely using Ki-67 proliferative indices - (from ENETS and WHO 2010) can be particularly helpful in further categorising these tumours. The natural history of Type 1 gastric carcinoids is generally (>95%) favourable and simple surveillance is usually recommended for small (<1 cm) T1 tumours, with local (endoscopic or surgical) resection for larger lesions. Other potential therapies such as somatostatin analogues and gastrin receptor antagonists may offer newer therapeutic possibilities. Rarely, gastric NENs have a malignant course and this is usually confined to Type 2 and especially Type 3 tumours; the latter mimic the biological course of gastric adenocarcinoma and require radical oncological therapies. Most duodenal NENs, apart from gastrinomas (that are not dealt with here) are sporadic and non functional. They are also increasing in frequency probably due to incidental discovery at endoscopy or imaging for other reasons and this may account for their overall good prognosis. Peri-ampullary and ampullary NENs may have a more aggressive outcome and should be carefully appraised and treated (often with surgical resection).

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.

6 Article Sequential Everolimus and Sunitinib Treatment in Pancreatic Metastatic Well-Differentiated Neuroendocrine Tumours Resistant to Prior Treatments. 2017

Angelousi, Anna / Kamp, Kimberly / Kaltsatou, Maria / O'Toole, Dermot / Kaltsas, Gregory / de Herder, Wouter. ·Sector of Endocrinology, Department of Pathophysiology, National & Kapodistrian University of Athens, Athens, Greece. ·Neuroendocrinology · Pubmed #28122378.

ABSTRACT: OBJECTIVE: Alternating treatment with sunitinib and everolimus has been shown to be efficacious in renal cell carcinoma. However, no data currently exist for the role of alternate sequence administration of these agents in well-differentiated pancreatic neuroendocrine tumours (pNETs). METHODS: Thirty-one patients were administered one compound and upon progression were switched to the other. All patients had grade 1 or 2 tumours and stage IV disease with similar metastatic load. The primary end point included estimation of the median overall progression-free survival (mPFS) along with each drug's mPFS as a first-line (mPFS1) and a second-line treatment (mPFS2); tolerability and serious adverse events were also evaluated. Secondary end points included overall survival (OS), 2-year mortality rate, and incidence of disease progression. RESULTS: Overall, mPFS did not differ between the everolimus to sunitinib group (36.5 months) and the sunitinib to everolimus group (31.6 months) with a hazard ratio of 0.94 ([95% CI, 0.45-1.97], p = 0.7). Although mPFS1 after first-line everolimus was longer (16.3 months) compared to sunitinib (9 months), this was not statistically significant (p = 0.15). Sequential second-line treatment showed no difference in the mPFS2 (p = 0.3). No difference in OS between the 2 groups was observed. Tolerability was better for everolimus compared to sunitinib. CONCLUSIONS: Treatment with sequential molecular target agents was well tolerated and associated with similar overall mPFS in both schemes of administration. Larger prospective studies are required to investigate the long-term efficacy and sequence of administration of alternate therapy with molecular targeting agents in metastatic pNETs and their effect on OS.

7 Article Osteoclastic-Type Giant Cell Tumours of the Pancreas: A Homogenous Series of Rare Tumours Diagnosed by Endoscopic Ultrasound. 2016

Lahiff, Conor / Swan, Niall / Conlon, Kevin / Malone, Dermot / Maguire, Donal / Hoti, Emir / Geoghegan, Justin / McEntee, Gerry / O'Toole, Dermot. ·Department of Gastroenterology, St. James's Hospital, Dublin, Ireland. ·Dig Surg · Pubmed #27160213.

ABSTRACT: BACKGROUND: Giant cell tumors (GCT) of the pancreas are a rare form of pancreatic cancer. Although data are limited, clinical outcomes appear to depend largely on histological subtype with osteoclastic tumors carrying a better prognosis. We report on a homogenous series of patients with osteoclastic-type GCTs of the pancreas presenting to a national pancreatico-biliary gastrointestinal oncology center. METHODS: Patients underwent endoscopic, radiological and histopathological assessments. Data were collected in relation to consecutive patients presenting with osteoclastic-type tumors of the pancreas and analyzed with survival as a primary end point. RESULTS: Four patients were treated over a 4-year period. Median age was 77 years with equal gender distribution. Median tumor size was 42 mm. Histology was osteoclast-type giant cells in all 4 patients. Two patients underwent surgery with curative intent. Median overall survival was 13.1 months. CONCLUSION: This is the largest reported series of osteoclast-type histology in GCTs of the pancreas.

ABSTRACT: Data on gastroenteropancreatic neuroendocrine neoplasms (NEN) G3 (well-differentiated neuroendocrine tumors (NET G3) and neuroendocrine carcinoma (NEC)) are limited. We retrospectively study patients with NET G3 and NEC from eight European centers. Data examined included clinical and pathological characteristics at diagnosis, therapies and outcomes. Two hundred and four patients were analyzed (37 NET G3 and 167 NEC). Median age was 64 (21-89) years. Tumor origin included pancreas (32%) and colon-rectum (27%). The primary tumor was resected in 82 (40%) patients. Metastatic disease was evident at diagnosis in 88% (liver metastases: 67%). Median Ki-67 index was 70% (30% in NET G3 and 80% in NEC; P<0.001). Median overall survival (OS) for all patients was 23 (95% CI: 18-28) months and significantly higher in NET G3 (99 vs 17 months in NEC; HR=8.3; P<0.001). Platinum-etoposide first line chemotherapy was administered in 113 (68%) NEC and 12 (32%) NET G3 patients. Disease control rate and progression free survival (PFS) were significantly higher in NEC compared to NET G3 (P<0.05), whereas OS was significantly longer in NET G3 (P=0.003). Second- and third-line therapies (mainly FOLFIRI and FOLFOX) were given in 79 and 39 of NEC patients; median PFS and OS were 3.0 and 7.6 months respectively after second-line and 2.5 and 6.2 months after third-line chemotherapy. In conclusion, NET G3 and NEC are characterized by significant differences in Ki-67 index and outcomes. While platinum-based chemotherapy is effective in NEC, it seems to have limited value in NET G3.

9 Article Initial impact of a systematic multidisciplinary approach on the management of patients with gastroenteropancreatic neuroendocrine tumor. 2013

ABSTRACT: According to the international guidelines, a multidisciplinary approach is currently advised for the optimal care of patients with a gastroenteropancreatic neuroendocrine tumor (GEP NET). In our institution (tertiary care center), a systematic multidisciplinary approach was established in May 2007. In this study, we have aimed to assess the initial impact of establishing a systematic multidisciplinary approach to the management of GEP NET patients. We have collected and compared the biochemical, imaging, and pathological data and the therapeutic strategies in GEP NET patients diagnosed, treated, or followed-up from January 1993 to April 2007 versus GEP NET patients attending our institution after the multidisciplinary approach starting, from May 2007 to October 2008. Data of 91 patients before and 42 patients after the establishment of the multidisciplinary approach (total: 133 consecutive GEP NET patients) have been finally collected and analyzed. Before the establishment of the multidisciplinary approach, a lack of consistency in the biochemical, imaging, and pathological findings before treatment initiation as well as during follow-up of GEP NET patients was identified. These inconsistencies have been reduced by the systematic multidisciplinary approach. In addition, the therapeutic management of GEP NET patients has been altered by the multidisciplinary approach and became more consistent with recommended guidelines. We think that a systematic multidisciplinary approach significantly impacts on GEP NET patient care and should be established in all centers dealing with these tumors.

ABSTRACT: Response rates to cytotoxics in gastro-entero-pancreatic neuroendocrine tumors (GEP-NETs) vary; recent trials demonstrated lack of objective response rates in up to 70% of patients. Identification of predictive therapeutic biomarkers would be beneficial in the treatment of GEP. Selected markers with known or suspected capability of predicting response to cytotoxics or prognosis (Ki-67, p53, multidrug resistance protein-1 (MDR1), Akt, thymidylate synthase (TS), phosphatase and tensin homolog (PTEN), CA9, cluster of differentiation 34 (CD34), vascular endothelial growth factor (VEGF), hypoxia-inducible factor (HIF)-1, mismatch repair gene - human mutL homolog 1 (hLMH1), and Bcl-2) were analyzed using immunohistochemisrtry in 60 treatment-naive patients receiving chemotherapy (n=46) or chemoembolization (n=14) for inoperable advanced and/or metastatic GEP and correlated with prognosis (survival and response rates). Therapy included systemic chemotherapy with streptozotocin (n=28), doxorubicin (n=14), 5-fluorouracil (n=18), and etoposide/cisplatinum (n=16), or chemoembolization (streptozotocin, 9; doxorubicin, 5). Factors associated with overall survival in the entire cohort were Ki-67, P<0.001; tumor grade, P<0.001; tumor differentiation, P<0.001; CA9, P=0.004; Akt, P=0.01; HIF-1, P<0.001; p53, P<0.0001; and hMLH1, P=0.005. Markers associated with treatment response included overall group: Akt and PTEN (P=0.05 and 0.05 respectively); streptozotocin: Akt (P=0.07), TS (P=0.02), and PTEN (P=0.017); doxorubicin: Ki-67 (P=0.05), Akt (P=0.06), and CA9 (P=0.02). At multivariate analysis, Akt was significantly associated with a nonresponse to therapy (objective response (OR): 0.2 (0.05-0.8)). For patients receiving only systemic chemotherapy (n=46), PTEN (0.04) and hLMH1 (0.03) were correlated with treatment response and for individual molecules were streptozotocin: PTEN (P=0.008) and hLMH1 (0.07); doxorubicin: Akt (P=0.09), CA9 (P=0.09), and hLMH1 (P=0.09). These results demonstrate a number of new prognostic biomarkers in GEP-NET, and in addition, response to chemotherapy was correlated with a simple panel of selected markers (such as CA9, Akt, PTEN, TS, and hLMH1).

12 Article Endoscopic ultrasound-guided fine-needle aspiration biopsy coupled with KRAS mutation assay to distinguish pancreatic cancer from pseudotumoral chronic pancreatitis. 2009

Bournet, B / Souque, A / Senesse, P / Assenat, E / Barthet, M / Lesavre, N / Aubert, A / O'Toole, D / Hammel, P / Levy, P / Ruszniewski, P / Bouisson, M / Escourrou, J / Cordelier, P / Buscail, L. ·Department of Gastroenterology and INSERM U858, University of Toulouse, CHU Rangueil, Toulouse, France. ·Endoscopy · Pubmed #19533561.

ABSTRACT: BACKGROUND AND STUDY AIMS: Differential diagnosis between pancreatic adenocarcinoma (PADC) and pseudotumoral forms of chronic pancreatitis remains difficult. Mutation of KRAS oncogene is present in 75% to 95% of PADC. This study aimed to evaluate whether the combined analysis of KRAS mutation with cytopathological findings from endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) might improve discrimination between PADC and chronic pancreatitis. PATIENTS AND METHODS: This prospective multicenter study included 178 patients with solid pancreatic masses (men 104, women 74; mean age 64.5 years). Cytopathological examination and KRAS mutation analysis (codon-12 and codon-13, restriction fragment length polymorphism [RFLP] and direct sequencing) were performed on EUS-FNAB material. Final diagnoses were obtained on EUS-FNAB analysis and/or a second biopsy and/or clinical follow-up and/or surgery: PADC, n = 129; chronic pancreatitis, n = 27; other pancreatic neoplasms, n = 16; and benign lesions, n = 6. RESULTS: KRAS status analysis was successful in all EUS-FNAB samples. Codon-12 KRAS point mutation was found in 66% of PADC samples. No case of chronic pancreatitis displayed KRAS mutation. Sensitivity, specificity, positive and negative predictive values, and overall accuracy of cytopathology alone for diagnosis of PADC versus chronic pancreatitis were 83%, 100%, 100%, 56% and 86%, respectively. When KRAS mutation analysis was combined with cytopathology, these values reached 88%, 100%, 100%, 63% and 90% respectively. CONCLUSION: Although the value of KRAS analysis in addition to EUS-FNAB is limited for distinguishing pancreatic mass lesions, when chronic pancreatitis presented as a pseudotumor a negative finding (wild-type KRAS), was useful in strongly suggesting a benign lesion.

13 Article Pancreatic portal cavernoma in patients with cavernous transformation of the portal vein: MR findings. 2009

ABSTRACT: The purpose of the article was to prospectively evaluate the MR findings of pancreatic portal cavernoma in a consecutive series of patients with cavernous transformation of the portal vein. This study was approved by the review board of our institution, and informed consent was obtained. The clinical and biological data and the MR imaging for 20 patients (11 female, 9 male; median age, 49 years) with cavernous transformation of the portal vein and no evidence of previous pancreatic disease were reviewed. The presence of pancreatic portal cavernoma (defined as intra- and/or peripancreatic portal cavernoma), morphological changes in the pancreas, biliary and ductal pancreatic abnormalities, and extension of the portal venous thrombosis were qualitatively assessed. Fifteen patients (75%) had pancreatic portal cavernoma with collateral formation in the pancreas and/or collaterals around the pancreas seen on dynamic contrast-enhanced MR sequences: three patients had both intra- and peripancreatic portal cavernoma, six had intrapancreatic portal cavernoma alone and six had peripancreatic portal cavernoma only. The presence of intra- or peripancreatic portal cavernoma was significantly associated with extension of the thrombosis to the splenic and superior mesenteric veins (p = 0.05). Morphological changes in the pancreas, heterogeneity on T2-weighted sequences and main ductal pancreatic abnormalities were seen in two, four and two patients, respectively. All these patients had intrapancreatic portal cavernoma. Bile duct dilatation was observed in 13 (65%) patients: among them three had extrahepatic dilatation only and these three patients had associated intrapancreatic portal cavernoma. In patients with cavernous transformation of the portal vein, intra- or peripancreatic portal cavernoma is common. In conclusion, intra- or peripancreatic portal cavernoma was only observed in patients with extension of the thrombosis to the splenic vein and/or the superior mesenteric vein.

ABSTRACT: The prevalence, clinical profiles and management of gastroenteropancreatic endocrine tumours (GEP) in France are not known. From August 1, 2001 to September 1, 2002, standardized records on patients with GEP were prospectively completed in 87 participating centres. The total group amounted to 668 patients (median age: 56 years, range: 12-89). WHO performance status was 0/1 for 80.2% of patients. The primary sites were the small bowel and colon (288), pancreas (211), unknown (77), stomach (33), non-digestive primary sites (24), appendix (20), rectum-anus (12), and oesophagus or cardia (3). GEP were functional in 260 patients (39%). Most pancreatic tumours were non-functional (72%). Metastatic disease was observed in 73.4% of cases. Most tumours (85.8%) were well or moderately differentiated. Somatostatin receptor scintigraphy was performed in only 55% of patients. The following treatment modalities were employed: resection of primary tumour: 66%; systemic chemotherapy: 41%; somatostatin analogues: 44 and 26% for GEP of small intestine and pancreas, respectively; interferon: 12%, and intra-arterial hepatic (chemo)embolization in 23 and 15% of GEP arising from the midgut and pancreas, respectively. Despite their low prevalence, well-differentiated GEP represent a significant and heterogeneous clinical group, which warrants improved medical education, referral to expert centres at an early stage, and the design of prospective therapeutic trials.

Maire, Frédérique / Voitot, Hélène / Aubert, Alain / Palazzo, Laurent / O'Toole, Dermot / Couvelard, Anne / Levy, Philippe / Vidaud, Michel / Sauvanet, Alain / Ruszniewski, Philippe / Hammel, Pascal. ·Pôle des Maladies de l'Appareil Digestif, Service de Gastroentérologie-Pancréatologie, Hôpital Beaujon, AP-HP, Clichy, France. ·Am J Gastroenterol · Pubmed #18775021.

ABSTRACT: INTRODUCTION: The preoperative diagnosis of intraductal papillary mucinous neoplasms (IPMN) of the pancreas must be as reliable as possible because large or even total pancreatectomy may be necessary. Early diagnosis of malignant forms is important to improve prognosis. The diagnostic accuracy of fluid analysis using endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) has been confirmed in cystic lesions of the pancreas. It is not known if these results can be applied to IPMN. AIMS: To determine the levels of biochemical and tumor markers in fluid from EUS-FNA in patients with IPMN and to assess the impact on the diagnosis of IPMN. PATIENTS AND METHODS: In total, 41 patients (14 men, median age 64 yr) underwent EUS-FNA before surgical resection of IPMN in our center. Levels of amylase, lipase, carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 19.9, and CA 72.4 were measured in the cyst fluid. The performance of the markers was retrospectively evaluated for: (a) a positive diagnosis of IPMN, using cutoffs validated in the literature for mucinous pancreatic lesions and (b) an assessment of malignancy (i.e., high-grade dysplasia or invasive carcinoma) compared with the final pathological examination of the surgical specimen. RESULTS: EUS-FNA was performed in dilated branch ducts (BD) in 39 cases and in the main pancreatic duct in 2 cases. No serious complications occurred. The median fluid levels of amylase, lipase, CEA, CA 19.9, and CA 72.4 were 20,155 U/mL, 59,500 U/mL, 173 ng/mL, 6,400 U/mL, and 11.5 U/mL, respectively. A CEA level >200 ng/mL and a CA 72.4 >40 U/mL had a 44% and a 39% sensitivity, respectively, for the diagnosis of IPMN. The levels of CEA, CA 19.9, and CA 72.4 were significantly different between benign and malignant IPMN. The sensitivity, specificity, and positive (PPV) and negative predictive values (NPV) of a CEA level >200 ng/mL for the diagnosis of malignant IPMN were 90%, 71%, 50%, and 96%, respectively. The sensitivity, specificity, PPV, and NPV of a CA 72.4 level >40 U/mL for this purpose were 87.5%, 73%, 47%, and 96%, respectively. CONCLUSION: CEA and CA 72.4 in pancreatic cyst fluid have excellent NPVs in the preoperative differential diagnosis of benign versus malignant IPMN, and might reinforce the decision of not to operate on patients with BD-type without predictive factors of malignancy.

ABSTRACT: BACKGROUND & AIMS: Because there is a low risk of malignancy for intraductal papillary and mucinous neoplasms of the pancreas (IPMNs) confined to branch ducts (BD), patient follow-up evaluation without surgery is possible. The aim of this study was to assess time-related morphologic changes and risk of progress to malignancy in patients with BD IPMN. A prospective design was used in an academic tertiary referral center. METHODS: All consecutive patients seen from 1999 to 2005 with highly suspected IPMNs confined to BD without criteria suggesting a malignant development (mural nodule, cyst wall thickness >2 mm, BD diameter >30 mm, or main pancreatic duct involvement) were followed up prospectively using computerized tomography, magnetic resonance cholangiopancreatography, and endoscopic ultrasonography. RESULTS: A total of 121 patients (median age, 63 y) were included. After a median follow-up period of 33 months, no morphologic changes had occurred in 88 patients. The size of the cyst increased in 30 of the 33 remaining patients, and 12 developed criteria suggesting a malignant development. Surgery, performed in 8 of 12 patients, found 4 IPMN-adenomas, 1 borderline-IPMN, and 4 IPMN carcinoma in situ. The 4 remaining patients did not undergo surgery because of severe comorbid conditions in 2, change in reference hospital in 1, and a mural nodule considered being sequelae of previous fine-needle aspiration in 1 patient. The only factor associated with signs suggesting malignant development was an increase in cyst size to more than 5 mm during the follow-up evaluation. CONCLUSIONS: In patients with IPMNs confined to BD, morphologic changes are rare events, justifying a nonsurgical approach. Careful follow-up evaluation remains necessary, particularly in patients with an increase in BD size.
