ABSTRACT: While abutment, encasement or vessel occlusion are identified in most patients with a pancreatic tumor, tumor thrombosis is an uncommon finding. In particular, there are no description in the literature of tumor thrombosis associated with ductal adenocarcinoma, the most common pancreatic tumor. On the other hand, surgical series reveal that tumor thrombosis is associated with about 5% of pancreatic neuroendocrine neoplasms (PanNENs), and literature data suggest that this finding is frequently underreported on pre-operative imaging examinations. Tumor thrombosis may be clinically relevant, causing splenoportomesenteric hypertension, possibly responsible for life-threatening upper gastrointestinal bleeding. Bland thrombosis caused by direct infiltration of peri-pancreatic vessels frequently determines surgical unresectability, even in neuroendocrine tumors; on the opposite, tumor thrombosis associated with PanNENs do not exclude surgery per se, even though both morbidity and mortality can be increased by such condition. Considering the favorable prognosis of PanNENs and the frequent need to treat tumor thrombosis in order to prevent complications or to relieve symptoms, it is of paramount importance for radiologists the knowledge of the variety of findings associated with tumor thrombosis in PanNENs.

2 Review Robotic pancreatectomies. 2016

Ramera, Marco / Damoli, Isacco / Giardino, Alessandro / Bassi, Claudio / Butturini, Giovanni. ·General Surgery Unit B, The Pancreas Institute, Verona University Hospital Trust. · Hepato-Pancreato-Biliary Unit, Casa di Cura Pederzoli, Peschiera del Garda, Verona, Italy, gbutturini@cdcpederzoli.it. ·Robot Surg · Pubmed #30697553.

ABSTRACT: Pancreatic surgery represents one of the most challenging fields in general surgery. Its complexity is related to the severity of the disease and the technical skills required for surgical approach. Given this, most pancreatic resections are performed through classic open surgery. Minimally invasive approaches are gradually gaining widespread popularity also in this specific setting, as for distal resections and enucleations. The robotic platform, due to its 3-dimensional vision and articulated movements, represents the natural progress of laparoscopic surgery overcoming the technical defaults and opening up the possibility to perform major pancreatic resections as pancreaticoduodenectomies. This review focuses on the impact of robotic platform in pancreatic surgery in terms of surgical and oncological outcome.

3 Review The prognostic impact of para-aortic lymph node metastasis in pancreatic cancer: A systematic review and meta-analysis. 2016

Paiella, S / Sandini, M / Gianotti, L / Butturini, G / Salvia, R / Bassi, C. ·Unit of General Surgery B, The Pancreas Institute, University of Verona Hospital Trust, Verona, Italy. Electronic address: salvatore.paiella@ospedaleuniverona.it. · Department of Surgery and Translational Medicine, Milano Bicocca University, Monza, Italy. · Unit of General Surgery B, The Pancreas Institute, University of Verona Hospital Trust, Verona, Italy. ·Eur J Surg Oncol · Pubmed #26916137.

ABSTRACT: PURPOSE: To evaluate by a meta-analytic approach the long-term prognostic impact of para-aortic lymph node (PALN) involvement in resected ductal adenocarcinoma of the pancreas. METHODS: MEDLINE, Embase, PubMed and the Cochrane Library were searched from January 1990 to June 2015. Trials reporting Kaplan-Meier curves and comparing overall long-term survival of negative and metastatic PALN in patients who underwent resection for pancreatic cancer were included. Lymph nodes were classified according to the Japan Pancreatic Society rules and identified using hematoxylin and eosin staining. Hazard ratios (HRs) and 95%CI were estimated for each trial and pooled in a meta-analysis. RESULTS: Thirteen eligible studies including 2141 patients (364 positive PALN; 1777 negative PALN) were identified. Most of the studies were retrospective. Heterogeneity among trials was high (I(2) = 98.7%; p < .001). PALN metastasis was associated with increased mortality when compared with patients with negative PALN regardless regional nodal status [HR 1.85, 95%CI 1.48-2.31; p < .001]. Median survival was significantly decreased in patients with positive PALN (WMD = -4.92 months 95%CI -6.40; -3.43; p < .001). Moreover, metastatic PALN affected mortality also when regional lymph nodes were positive [HR 1.67, 95%CI 1.34-2.08; p < .001]. No publication bias was detected. CONCLUSIONS: PALN metastasis appears to correlate with poor prognosis in patients with pancreatic adenocarcinoma. The assessment of PALN status may be considered for a more accurate staging of the disease and appropriated subgroup survival reporting. However, the definitive avoidance of the resection in case of intraoperative metastatic PALN needs further investigation.

4 Review Uncommon presentations of common pancreatic neoplasms: a pictorial essay. 2015

D'Onofrio, Mirko / De Robertis, Riccardo / Capelli, Paola / Tinazzi Martini, Paolo / Crosara, Stefano / Gobbo, Stefano / Butturini, Giovanni / Salvia, Roberto / Barbi, Emilio / Girelli, Roberto / Bassi, Claudio / Pederzoli, Paolo. ·Department of Radiology, G.B.

ABSTRACT: Pancreatic neoplasms are a wide group of solid and cystic lesions with different and often characteristic imaging features, clinical presentations, and management. Among solid tumors, ductal adenocarcinoma is the most common: it arises from exocrine pancreas, comprises about 90% of all pancreatic neoplasms, and generally has a bad prognosis; its therapeutic management must be multidisciplinary, involving surgeons, oncologists, gastroenterologists, radiologists, and radiotherapists. The second most common solid pancreatic neoplasms are neuroendocrine tumors: they can be divided into functioning or non-functioning and present different degrees of malignancy. Cystic pancreatic neoplasms comprise serous neoplasms, which are almost always benign, mucinous cystic neoplasms and intraductal papillary mucinous neoplasms, which can vary from benign to frankly malignant lesions, and solid pseudopapillary tumors. Other pancreatic neoplasms, such as lymphoma, metastases, or pancreatoblastoma, are rarely seen in clinical practice and have different and sometimes controversial managements. Rare clinical presentations and imaging appearance of the most common pancreatic neoplasms, both solid and cystic, are more frequently seen and clinically relevant than rare pancreatic tumors; their pathologic and radiologic appearances must be known to improve their management. The purpose of this paper is to present some rare or uncommon clinical and radiological presentations of common pancreatic neoplasms providing examples of multi-modality imaging approach with pathologic correlations, thus describing the histopathological bases that can explain the peculiar imaging features, in order to avoid relevant misdiagnosis and to improve lesion management.

5 Review Clinical implications of biological markers in Pancreatic Ductal Adenocarcinoma. 2012

Giovinazzo, Francesco / Turri, Giulia / Zanini, Sara / Butturini, Giovanni / Scarpa, Aldo / Bassi, Claudio. ·Laboratory of Translational Surgery, University Laboratories of Medical Research (LURM), G.B. Rossi Hospital, University of Verona, Piazzale L.A. Scuro 10, Verona 37134, Italy. ·Surg Oncol · Pubmed #22981281.

ABSTRACT: Pancreatic Ductal Adenocarcinoma (PDAC) is a malignant neoplasm and is the fourth leading cause of cancer-related deaths in US with a 5-year survival rate less than 5%. Surgery is the only potentially curative treatment even though the result is a palliation in the majority of cases and the majority of lesions are lately diagnosed. Progression from normal pancreatic epithelium to metastatic disease is now a well-characterized sequence of events. Research has shown that pancreatic cancer is fundamentally a genetic disease with several biological pathway implied in apoptosis, cell proliferation and self-sufficiency in growth signaling, but how those findings could be applied in daily clinical practice remain unknown. Several studies tried to characterize diagnostic and prognostic biomarkers in PDAC to make it possible an earlier diagnosis, guarantee a more effective treatment and reach a better prognosis even though the results remain contrasting. The main limit of the published researches is the small number of patients studied, but even the heterogeneity of the used methods of analysis. Examining critically the research of the last years future trials may be addressed toward a translational models integrating "the bench and the bed" with the clinical experience and drive the basic research toward the clinical applications.

ABSTRACT: BACKGROUND: Placement of intraperitoneal drain (ID) after abdominal surgery is a common practice. Postoperative pancreatic fistula (POPF), incidence of which ranges from 2% to more than 30%, represents the most common major complication after pancreatic resection. The goal of this paper is to review the state of the art in ID management after pancreatic resection. METHODS: Data from randomized controlled trials (RCT) are reported together with data from our institution in the period before and after the start of the two reported RCTs. RESULTS: One thousand five hundred eighty patients underwent surgical resection for pancreatic lesions at our institution from 1990 to 2010. The overall rate of POPF was 23% before and 19.5% after (p = 0.24) the performance of the RCTs. Both postoperative morbidity and average in-hospital stay were higher in the period before the RCTs (13.6 ± 11.4 versus 13.4 ± 10.3 days, respectively). CONCLUSIONS: POPF is a complex and multifactorial complication after pancreatic surgery. On the basis of the present results and review of the RCTs, the value of ID and its management after pancreatic surgery remain unclear.

7 Review Pancreaticoduodenectomy for pancreatic cancer: the Verona experience. 2011

Malleo, Giuseppe / Marchegiani, Giovanni / Salvia, Roberto / Butturini, Giovanni / Pederzoli, Paolo / Bassi, Claudio. ·Department of Surgery, General Surgery B, G.B. Rossi Hospital, P.Le L.A. Scuro 10, 37134, Verona, Italy. ·Surg Today · Pubmed #21431477.

ABSTRACT: Pancreatic ductal adenocarcinoma is the fourth leading cause of cancer-related mortality in the Western world. The current treatment is multimodal, and in resectable patients radical surgery represents the key-step toward long-term survival. Pancreaticoduodenectomy (PD) is the most widely performed operation, because the majority of ductal carcinomas arise in the head of the pancreas. Once considered extremely hazardous, PD has evolved into a safe procedure, with mortality below 5% and morbidity rates in the range from 20% to 60% at high-volume centers. Verona is regarded as one of the most prominent institutions for pancreatic surgery in Europe. More than 5500 patients with pancreatic diseases have been managed, and the surgical case load has increased substantially, with more than 1350 PDs performed. This review discusses this center's experience in surgical treatment of pancreatic head cancer. Furthermore, the preliminary results of radiofrequency thermal ablation of locally advanced ductal cancer are presented.

8 Review Aggressive approach to acinar cell carcinoma of the pancreas: a single-institution experience and a literature review. 2011

Butturini, Giovanni / Pisano, Michele / Scarpa, Aldo / D'Onofrio, Mirko / Auriemma, Alessandra / Bassi, Claudio. ·Surgical Department, Verona University Hospital, Piazzale La Scuro 10, Verona, Italy. giovanni.butturini@ospedaleuniverona.it ·Langenbecks Arch Surg · Pubmed #20803029.

ABSTRACT: PURPOSE: Acinar cell carcinomas (ACCs) are a rare pancreatic tumor group with no standardized treatment. The aim of the study is to analyze the clinical and pathologic characteristics of our series and to review the current literature. METHODS: Retrospective review of prospectively collected data from 1990 to 2007 included patients who underwent pancreatic resection for histologically proven ACCs. All specimens of ACC were rereviewed by an expert pathologist. Follow-up was updated to October 2009. A literature search was performed by Pubmed and COCHRANE library. RESULTS: Among 1,210 patients who underwent pancreatic resection, we identified nine ACCs. R0 resection was possible for all but one R1. We had no major complications and no mortality. All nine cases were diagnosed as pure ACCs. Five patients received adjuvant chemotherapy. Median overall survival was 31 months, while median disease-free survival was 18 months. All patients developed liver metastases, requiring modification of chemotherapeutic schema, radiofrequency ablation techniques, or reiterate surgery. Currently, only one patient is alive without evidence of disease 85 months after pancreatic resection. One patient is alive 52 months after operation, with evidence of recurrent disease. CONCLUSIONS: ACC represents a rare solid tumor of the pancreas. Prognosis is dismal, although, compared to the more common ductal adenocarcinoma, survival appears to be longer. Patients with metastatic disease might benefit from aggressive multimodality treatments.

9 Review Clinicopathological features of adenosquamous pancreatic cancer. 2011

Regi, Paolo / Butturini, Giovanni / Malleo, Giuseppe / Pedica, Federica / D'Onofrio, Mirko / Bassi, Claudio. ·Surgical and Gastroenterological Department, University of Verona, Policlinico Borgo Roma, Piazzale LA Scuro #10, 37134 Verona, Italy. paoloregi@tiscali.it ·Langenbecks Arch Surg · Pubmed #20617336.

ABSTRACT: PURPOSE: Adenosquamous pancreatic cancer represents 0.9-4.4% of exocrine pancreatic neoplasms and is generally thought to be associated with a worse prognosis than the more common ductal adenocarcinoma. The aim of the current study is to describe the outcome of patients with adenosquamous pancreatic cancer in our institution who were managed in a multidisciplinary environment. METHODS: In a retrospective analysis between February 1990 and February 2010, we identified from our database of 890 pancreatic lesions resected for malignancy six cases (0.67%) of adenosquamous cancer. We assessed the demographics, clinical and radiological features, surgical approach, histological details and follow-up data. RESULTS: All patients underwent pylorus-preserving pancreatoduodenectomy. Two patients, one male and one female, died in the preoperative period due to sepsis and myocardial infarction, respectively. The remaining four patients received adjuvant chemotherapy. One male patient died with local recurrence after 13 months; however, one female and two male patients are still alive with Karnofsky status of 80-90% at 15, 14 and 39 months after the operation, respectively. CONCLUSIONS: The prognosis of adenosquamous pancreatic cancer remains very poor, apparently worse than ductal pancreatic cancer. Nevertheless, our report and the review of literature seem to show that "curative" surgical resection associated with adjuvant treatment may offer the best results with a similar survival rate than ductal pancreatic cancer.

10 Review Pancreatic cystic tumours: when to resect, when to observe. 2010

Salvia, R / Crippa, S / Partelli, S / Malleo, G / Marcheggiani, G / Bacchion, M / Butturini, G / Bassi, C. ·Department of Surgery, Chirurgia Generale B, Policlinico "GB Rossi", University of Verona, Verona, Italy. ·Eur Rev Med Pharmacol Sci · Pubmed #20496554.

ABSTRACT: BACKGROUND AND OBJECTIVES: In recent years there has been an increase in the diagnosis of cystic tumors of the pancreas. In this setting, difficult diagnostic problems and different therapeutic management can be proposed. MATERIAL AND METHODS: A review of the literature and authors experience were undertaken. RESULTS: Cystic tumors of the pancreas include different neoplasms with a different biological behaviour. While most serous cystadenomas (SCAs) can be managed nonoperatively, patients with mucinous cystic neoplasms (MCNs), solid pseudopapillary tumors (SPTs), main-duct intraductal papillary mucinous neoplasms (IPMNs) should undergo surgical resection. Branch-duct IPMNs can be observed with radiological and clinical follow-up when asymptomatic, < 3 cm in size and without radiologic features of malignancy (i.e. nodules). CONCLUSIONS: Cystic tumors of the pancreas are common. Differential diagnosis among the different tumor-types is of paramount importance for appropriate management. Nonoperative management seems appropriate for most SCAs and for well-selected branch-duct IPMNs.

11 Clinical Trial Safety and feasibility of Irreversible Electroporation (IRE) in patients with locally advanced pancreatic cancer: results of a prospective study. 2015

Paiella, Salvatore / Butturini, Giovanni / Frigerio, Isabella / Salvia, Roberto / Armatura, Giulia / Bacchion, Matilde / Fontana, Martina / D'Onofrio, Mirko / Martone, Enrico / Bassi, Claudio. ·Unit of Pancreatic and General Surgery, The Pancreas Institute, G.B. Rossi Hospital, University of Verona Hospital Trust, Verona, Italy. ·Dig Surg · Pubmed #25765775.

ABSTRACT: PURPOSE: To evaluate the safety of the NanoKnife Low Energy Direct Current (LEDC) System (Irreversible Electroporation, IRE) in order to treat patients with unresectable pancreatic adenocarcinoma. METHODS: Prospective, nonrandomized, single-center clinical evaluation of ten patients with a cytohystological diagnosis of unresectable locally advanced pancreatic cancer (LAPC) that was no further responsive to standard treatments. The primary outcome was the rate of procedure-related abdominal complications. The secondary endpoints included the evaluation of the short-term efficacy of IRE through the evaluation of tumor reduction at imaging and biological tumor response as shown by CA 19-9, clinical assessments and patient quality of life. RESULTS: Ten patients (5 males, 5 females) were enrolled, with a median age of 66 and median tumor size of 30 mm. All patients were treated successfully with a median procedure time of 79.5 min. Two procedure-related complications were described in one patient (10%): a pancreatic abscess with a pancreoduodenal fistula. Three patients had early progression of disease: one patient developed pulmonary metastases 30 days post-IRE and two patients had liver metastases 60 days after the procedure. We registered an overall survival of 7.5 months (range: 2.9-15.9). CONCLUSIONS: IRE is a safe procedure in patients with LAPC and may represent a new technological option in the treatment and multimodality management of this disease.

ABSTRACT: PURPOSE: Adjuvant chemotherapy improves patient survival rates after resection for pancreatic adenocarcinoma, but the optimal duration and time to initiate chemotherapy is unknown. PATIENTS AND METHODS: Patients with pancreatic ductal adenocarcinoma treated within the international, phase III, European Study Group for Pancreatic Cancer-3 (version 2) study were included if they had been randomly assigned to chemotherapy. Overall survival analysis was performed on an intention-to-treat basis, retaining patients in their randomized groups, and adjusting the overall treatment effect by known prognostic variables as well as the start time of chemotherapy. RESULTS: There were 985 patients, of whom 486 (49%) received gemcitabine and 499 (51%) received fluorouracil; 675 patients (68%) completed all six cycles of chemotherapy (full course) and 293 patients (30%) completed one to five cycles. Lymph node involvement, resection margins status, tumor differentiation, and completion of therapy were all shown by multivariable Cox regression to be independent survival factors. Overall survival favored patients who completed the full six courses of treatment versus those who did not (hazard ratio [HR], 0.516; 95% CI, 0.443 to 0.601; P < .001). Time to starting chemotherapy did not influence overall survival rates for the full study population (HR, 0.985; 95% CI, 0.956 to 1.015). Chemotherapy start time was an important survival factor only for the subgroup of patients who did not complete therapy, in favor of later treatment (P < .001). CONCLUSION: Completion of all six cycles of planned adjuvant chemotherapy rather than early initiation was an independent prognostic factor after resection for pancreatic adenocarcinoma. There seems to be no difference in outcome if chemotherapy is delayed up to 12 weeks, thus allowing adequate time for postoperative recovery.

13 Clinical Trial Adjuvant chemotherapy with fluorouracil plus folinic acid vs gemcitabine following pancreatic cancer resection: a randomized controlled trial. 2010

ABSTRACT: CONTEXT: Adjuvant fluorouracil has been shown to be of benefit for patients with resected pancreatic cancer. Gemcitabine is known to be the most effective agent in advanced disease as well as an effective agent in patients with resected pancreatic cancer. OBJECTIVE: To determine whether fluorouracil or gemcitabine is superior in terms of overall survival as adjuvant treatment following resection of pancreatic cancer. DESIGN, SETTING, AND PATIENTS: The European Study Group for Pancreatic Cancer (ESPAC)-3 trial, an open-label, phase 3, randomized controlled trial conducted in 159 pancreatic cancer centers in Europe, Australasia, Japan, and Canada. Included in ESPAC-3 version 2 were 1088 patients with pancreatic ductal adenocarcinoma who had undergone cancer resection; patients were randomized between July 2000 and January 2007 and underwent at least 2 years of follow-up. INTERVENTIONS: Patients received either fluorouracil plus folinic acid (folinic acid, 20 mg/m(2), intravenous bolus injection, followed by fluorouracil, 425 mg/m(2) intravenous bolus injection given 1-5 days every 28 days) (n = 551) or gemcitabine (1000 mg/m(2) intravenous infusion once a week for 3 of every 4 weeks) (n = 537) for 6 months. MAIN OUTCOME MEASURES: Primary outcome measure was overall survival; secondary measures were toxicity, progression-free survival, and quality of life. RESULTS: Final analysis was carried out on an intention-to-treat basis after a median of 34.2 (interquartile range, 27.1-43.4) months' follow-up after 753 deaths (69%). Median survival was 23.0 (95% confidence interval [CI], 21.1-25.0) months for patients treated with fluorouracil plus folinic acid and 23.6 (95% CI, 21.4-26.4) months for those treated with gemcitabine (chi(1)(2) = 0.7; P = .39; hazard ratio, 0.94 [95% CI, 0.81-1.08]). Seventy-seven patients (14%) receiving fluorouracil plus folinic acid had 97 treatment-related serious adverse events, compared with 40 patients (7.5%) receiving gemcitabine, who had 52 events (P < .001). There were no significant differences in either progression-free survival or global quality-of-life scores between the treatment groups. CONCLUSION: Compared with the use of fluorouracil plus folinic acid, gemcitabine did not result in improved overall survival in patients with completely resected pancreatic cancer.

Electronic address: claudio.bassi@univr.it. ·Pancreatology · Pubmed #31005377.

ABSTRACT: BACKGROUND: Pancreatico-enteric anastomosis after pancreaticoduodenectomy can be performed using either a pancreaticojejunostomy (PJ) or pancreaticogastrostomy (PG). Differences in surgical outcomes are still a matter of debate, and less is known about long-term functional outcomes. METHODS: Twelve years after the conclusion of a comparative study evaluating the surgical outcomes of PJ and PG (Bassi et al., Ann Surg 2005), available patients underwent morphological and functional pancreatic assessment: pancreatic volume and duct diameter measured by MRI, impaired secretion after secretin, fecal fat, fecal elastase-1 (FE-1), serum vitamin D and endocrine function. Quality of life and symptom scores were evaluated with the EORTC QLQ-C30 questionnaire. RESULTS: Only 34 patients were available for assessment. No differences were found in terms of BMI variation, endocrine function, quality of life or symptoms. Exocrine function was more severely impaired after PG than after PJ (fecal fats 26.6 ± 4.1 vs 18.2 ± 3.6 g/day; FE-1 121.4 ± 6.7 vs 170.2 ± 25.5 μg/g, vitamin D 18.1 ± 1.8 vs. 23.2 ± 3.1 ng/mL). MRI assessment identified a lower pancreatic volume (26 ± 3.1 vs. 36 ± 4.1 cm CONCLUSION: Compared to PJ, PG is associated with a more severely impaired exocrine function long-term, but they result similar endocrine function and quality of life. In patients with a long life expectancy, this should be taken into account.

ABSTRACT: OBJECTIVE: The aim of this study was to compare oncological outcomes after minimally invasive distal pancreatectomy (MIDP) with open distal pancreatectomy (ODP) in patients with pancreatic ductal adenocarcinoma (PDAC). BACKGROUND: Cohort studies have suggested superior short-term outcomes of MIDP vs. ODP. Recent international surveys, however, revealed that surgeons have concerns about the oncological outcomes of MIDP for PDAC. METHODS: This is a pan-European propensity score matched study including patients who underwent MIDP (laparoscopic or robot-assisted) or ODP for PDAC between January 1, 2007 and July 1, 2015. MIDP patients were matched to ODP patients in a 1:1 ratio. Main outcomes were radical (R0) resection, lymph node retrieval, and survival. RESULTS: In total, 1212 patients were included from 34 centers in 11 countries. Of 356 (29%) MIDP patients, 340 could be matched. After matching, the MIDP conversion rate was 19% (n = 62). Median blood loss [200 mL (60-400) vs 300 mL (150-500), P = 0.001] and hospital stay [8 (6-12) vs 9 (7-14) days, P < 0.001] were lower after MIDP. Clavien-Dindo grade ≥3 complications (18% vs 21%, P = 0.431) and 90-day mortality (2% vs 3%, P > 0.99) were comparable for MIDP and ODP, respectively. R0 resection rate was higher (67% vs 58%, P = 0.019), whereas Gerota's fascia resection (31% vs 60%, P < 0.001) and lymph node retrieval [14 (8-22) vs 22 (14-31), P < 0.001] were lower after MIDP. Median overall survival was 28 [95% confidence interval (CI), 22-34] versus 31 (95% CI, 26-36) months (P = 0.929). CONCLUSIONS: Comparable survival was seen after MIDP and ODP for PDAC, but the opposing differences in R0 resection rate, resection of Gerota's fascia, and lymph node retrieval strengthen the need for a randomized trial to confirm the oncological safety of MIDP.

ABSTRACT: BACKGROUND AND AIMS: Radiofrequency ablation (RFA) is a well-recognized local ablative technique applied in the treatment of different solid tumors. Intraoperative RFA has been used for non-metastatic unresectable pancreatic ductal adenocarcinoma (PDAC), showing increased overall survival in retrospective studies. A novel RFA probe has recently been developed, allowing RFA under endoscopic ultrasound (EUS) guidance. Aim of the present study was to assess the feasibility and safety of EUS-guided RFA for unresectable PDACs. METHODS: Patients with unresectable non-metastatic PDAC were included in the study following neoadjuvant chemotherapy. EUS-guided RFA was performed using a novel monopolar 18-gauge electrode with a sharp conical 1 cm tip for energy delivery. Pre- and post-procedural clinical and radiological data were prospectively collected. RESULTS: Ten consecutive patients with unresectable PDAC were enrolled. The procedure was successful in all cases and no major adverse events were observed. A delineated hypodense ablated area within the tumor was observed at the 30-day CT scan in all cases. CONCLUSIONS: EUS-guided RFA is a feasible and safe minimally invasive procedure for patients with unresectable PDAC. Further studies are warranted to demonstrate the impact of EUS-guided RFA on disease progression and overall survival.

ABSTRACT: BACKGROUND: In the last decade many studies showed that the exhaled breath of subjects suffering from several pathological conditions has a peculiar volatile organic compound (VOC) profile. The objective of the present work was to analyse the VOCs in alveolar air to build a diagnostic tool able to identify the presence of pancreatic ductal adenocarcinoma in patients with histologically confirmed disease. METHODS: The concentration of 92 compounds was measured in the end-tidal breath of 65 cases and 102 controls. VOCs were measured with an ion-molecule reaction mass spectrometry. To distinguish between subjects with pancreatic adenocarcinomas and controls, an iterated Least Absolute Shrinkage and Selection Operator multivariate Logistic Regression model was elaborated. RESULTS: The final predictive model, based on 10 VOCs, significantly and independently associated with the outcome had a sensitivity and specificity of 100 and 84% respectively, and an area under the ROC curve of 0.99. For further validation, the model was run on 50 other subjects: 24 cases and 26 controls; 23 patients with histological diagnosis of pancreatic adenocarcinomas and 25 controls were correctly identified by the model. CONCLUSIONS: Pancreatic cancer is able to alter the concentration of some molecules in the blood and hence of VOCs in the alveolar air in equilibrium. The detection and statistical rendering of alveolar VOC composition can be useful for the clinical diagnostic approach of pancreatic neoplasms with excellent sensitivity and specificity.

ABSTRACT: OBJECTIVES: To evaluate MRI derived whole-tumour histogram analysis parameters in predicting pancreatic neuroendocrine neoplasm (panNEN) grade and aggressiveness. METHODS: Pre-operative MR of 42 consecutive patients with panNEN >1 cm were retrospectively analysed. T1-/T2-weighted images and ADC maps were analysed. Histogram-derived parameters were compared to histopathological features using the Mann-Whitney U test. Diagnostic accuracy was assessed by ROC-AUC analysis; sensitivity and specificity were assessed for each histogram parameter. RESULTS: ADC CONCLUSIONS: Whole-tumour histogram analysis of ADC maps may be helpful in predicting tumour grade, vascular involvement, nodal and liver metastases in panNENs. ADC KEY POINTS: • Whole-tumour ADC histogram analysis can predict aggressiveness in pancreatic neuroendocrine neoplasms. • ADC entropy and kurtosis are higher in aggressive tumours. • ADC histogram analysis can quantify tumour diffusion heterogeneity. • Non-invasive quantification of tumour heterogeneity can provide adjunctive information for prognostication.

ABSTRACT: INTRODUCTION: Cystic pancreatic neuroendocrine tumors (CPanNETs) represent an uncommon variant of pancreatic neuroendocrine tumors (PanNETs). Due to their rarity, there is a lack of knowledge with regard to clinical features and postoperative outcome. METHODS: The prospectively maintained surgical database of a high-volume institution was queried, and 46 resected CPanNETs were detected from 1988 to 2015. Clinical, demographic, and pathological features and survival outcomes of CPanNETs were described and matched with a population of 92 solid PanNETs (SPanNETs) for comparison. RESULTS: CPanNETs accounted for 7.8% of the overall number of resected PanNETs (46/587). CPanNETs were mostly sporadic (n = 42, 91%) and nonfunctioning (39%). Two functioning CPanNETs were detected (4.3%), and they were 2 gastrinomas. The median tumor diameter was 30 mm (range 10-120). All tumors were well differentiated, with 38 (82.6%) G1 and 8 (17.4%) G2 tumors. Overall, no CPanNET showed a Ki-67 >5%. A correct preoperative diagnosis of a CPanNET was made in half of the cases. After a median follow-up of >70 months, the 5- and 10-year overall survival of resected CPanNETs was 93.8 and 62.5%, respectively, compared to 92.7 and 84.6% for SPanNETs (p > 0.05). The 5- and 10-year disease-free survival rates were 94.5 and 88.2% for CPanNETs and 81.8 and 78.9% for SPanNETs, respectively (p > 0.05). CONCLUSION: In the setting of a surgical cohort, CPanNETs are rare, nonfunctional, and well-differentiated neoplasms. After surgical resection, they share the excellent outcome of their well-differentiated solid counterparts for both survival and recurrence.

ABSTRACT: OBJECTIVE/BACKGROUND: RFA of pancreatic cancer has been demonstrated to be feasible and safe with a positive impact on survival. The aim was to investigate whether an immune reaction is activated after locally advanced pancreatic cancer (LAPC) ablation. METHODS: Peripheral Blood samples were obtained preoperatively and on post-operative days 3-30. Evaluated parameters were: cells [CD4 RESULTS: Ten patients were enrolled. CD4 CONCLUSIONS: This study provides the first evidence of RFA-based immunomodulation in LAPC. We observed a general activation of adaptive response along with a decrease of immunosuppression. Furthermore, most cells showed prolonged activation some weeks after the procedure, suggesting true immunomodulation rather than a normal inflammatory response.

ABSTRACT: BACKGROUND: Since prognosis and treatment of pancreatic endocrine tumors (pNET) are based on tumor grade, contrast-enhanced multidetector computed tomography (MDCT) features of solid non-functioning pNETs were studied and correlated with pathology tumor grading. METHODS: MDCTs of diagnosed pNETs were reviewed retrospectively. Each tumor was analyzed for location, size, homogeneity, margins, arterial and venous phase enhancement, main pancreatic duct diameter, calcifications, vascular invasion, lymph-nodes enlargement, and liver metastases. RESULTS: Of 154 pNETs presenting between January 2000 and May 2016 with available histology from resected specimen or biopsy, there were 65 G1, 72 G2 and 17 G3 pNETs. Tumor diameter varied significantly between the three groups. Tumors >20 mm were more frequently malignant and non-homogeneous than smaller tumors. G1 tumors were more commonly hypervascular and G3 tumors more often non-hypervascular in the arterial phase. Arterial phase non-hyperdensity and tumor non-homogeneity had a higher rate of metastatic lesions. Vascular invasion correlated with presence of metastases and histological grade. G3 tumors were all >20 mm (p = 0.007), more often non-hypervascular in the arterial phase (p = 0.0025), and non-hyperdense in the venous phase (p = 0.009), and showed more often vascular invasion (p = 0.0198). CONCLUSION: CT correlated with tumor grade; differentiating low-grade and high-grade pNETs through routine CT imaging might improve patient management.

ABSTRACT: AIM: To establish the ability of magnetic resonance (MR) and computer tomography (CT) to predict pathologic dimensions of pancreatic neuroendocrine tumors (PanNET) in a caseload of a tertiary referral center. METHODS: Patients submitted to surgery for PanNET at the Surgical Unit of the Pancreas Institute with at least 1 preoperative imaging examination (MR or CT scan) from January 2005 to December 2015 were included and data retrospectively collected. Exclusion criteria were: multifocal lesions, genetic syndromes, microadenomas or mixed tumors, metastatic disease and neoadjuvant therapy. Bland-Altman (BA) and Mountain-Plot (MP) statistics were used to compare size measured by each modality with the pathology size. Passing-Bablok (PB) regression analysis was used to check the agreement between MR and CT. RESULTS: Our study population consisted of 292 patients. Seventy-nine (27.1%) were functioning PanNET. The mean biases were 0.17 ± 7.99 mm, 1 ± 8.51 mm and 0.23 ± 9 mm, 1.2 ± 9.8 mm for MR and CT, considering the overall population and the subgroup of non-functioning- PanNET, respectively. Limits of agreement (LOA) included the vast majority of observations, indicating a good agreement between imaging and pathology. The MP further confirmed this finding and showed that the two methods are unbiased with respect to each other. Considering ≤ 2 cm non-functioning-PanNET, no statistical significance was found in the size estimation rate of MR and CT ( CONCLUSION: MR and CT scan are accurate and interchangeable imaging techniques in predicting pathologic dimensions of PanNET.

ABSTRACT: BACKGROUND: Recent papers consider surgery as an option for synchronous liver oligometastatic patients [metastatic pancreatic ductal adenocarcinoma (mPDAC)]. In this study, we present our series of resected mPDACs after neoadjuvant chemotherapy (nCT). PATIENTS AND METHODS: All patients resected after downstaging of mPDAC were included in this study. Downstaging criteria were disappearance of liver metastasis and a decrease in cancer antigen (CA) 19-9. The type and duration of nCT, last nCT surgery interval, histology, morbidity, and mortality were recorded, and overall survival (OS) and disease-free survival (DFS) were analyzed. RESULTS: Overall, 24 of 535 patients (4.5%) observed with mPDAC were included. These patients received gemcitabine alone (5/24), gemcitabine + nanoparticle albumin-bound (nab)-paclitaxel (3/24), and FOLFIRINOX (16/24). Primary tumor size decreased from 31 to 19 mm (p < 0.001), and serum CA19-9 decreased from 596 to 18 U/mL (p < 0.001). In 14/24 patients, the tumor was located in the head. Median interval nCT surgery was 2 months, there were no mortalities, and the postoperative course was uneventful in 34% of cases. Grade B/C pancreatic fistula, postoperative bleeding, and sepsis occurred in 17/4, 4, and 12% of cases, respectively, and reoperation rate was 4%. R0 resection was achieved in 88% of cases, with 17% complete pathological response. Positive nodes were found in 9/24 patients with a median node ratio of 0.37, and OS and DFS was 56 and 27 months, respectively. CONCLUSIONS: Patients with mPDAC who were fully responsive to nCT may be cautiously considered for surgery, with potential benefit in survival compared with palliative chemotherapy alone. This is supported by results of our retrospective study, which is the largest ever reported.

ABSTRACT: The diagnosis of pancreatic neuroendocrine tumours (PanNETs) is increasing owing to more sensitive detection methods, and this increase is creating challenges for clinical management. We performed whole-genome sequencing of 102 primary PanNETs and defined the genomic events that characterize their pathogenesis. Here we describe the mutational signatures they harbour, including a deficiency in G:C > T:A base excision repair due to inactivation of MUTYH, which encodes a DNA glycosylase. Clinically sporadic PanNETs contain a larger-than-expected proportion of germline mutations, including previously unreported mutations in the DNA repair genes MUTYH, CHEK2 and BRCA2. Together with mutations in MEN1 and VHL, these mutations occur in 17% of patients. Somatic mutations, including point mutations and gene fusions, were commonly found in genes involved in four main pathways: chromatin remodelling, DNA damage repair, activation of mTOR signalling (including previously undescribed EWSR1 gene fusions), and telomere maintenance. In addition, our gene expression analyses identified a subgroup of tumours associated with hypoxia and HIF signalling.

ABSTRACT: AIM: To describe magnetic resonance (MR) imaging features of pancreatic neuroendocrine neoplasms (PanNENs) according to their grade and tumor-nodes-metastases stage by comparing them to histopathology and to determine the accuracy of MR imaging features in predicting their biological behavior. METHODS: This study was approved by our institutional review board; requirement for informed patient consent was waived due to the retrospective nature of the study. Preoperative MR examinations of 55 PanNEN patients (29 men, 26 women; mean age of 57.6 years, range 21-83 years) performed between June 2013 and December 2015 were reviewed. Qualitative and quantitative features were compared between tumor grades and stages determined by histopathological analysis. RESULTS: Ill defined margins were more common in G2-3 and stage III-IV PanNENs than in G1 and low-stage tumors ( CONCLUSION: MR features of PanNENs vary according to their grade of differentiation and their stage at diagnosis and could predict the biological behavior of these tumors.
