ABSTRACT: BACKGROUND: Previous studies on statins' effect on survival of patients with pancreatic ductal adenocarcinoma (PDAC) report conflicting results. AIMS: To evaluate the association between statin use and PDAC patients' survival. METHODS: A systematic review and meta-analysis was performed including case-control, cohort studies and randomized controlled trials assessing the association between statin use and survival in PDAC patients. Pooled HRs with 95%CIs were calculated using random effects model; publication bias was assessed through Begg and Mazumdar test and heterogeneity by I RESULTS: 14 studies with 33,137 PDAC patients, 40% under statins, were included. Statins use was associated to a reduced death risk (HR 0.871; 95%CI: 0.819; 0.927; p = 0.0001) suggesting a protective effect, homogeneous for different geographic areas. This effect was significant in surgically resected patients (HR 0.50; 95%CI: 0.32; 0.76; p = 0.001) but not in those with advanced disease (HR 0.78; 95%CI: 0.59; 1.02; p = 0.07). In studies providing information on statin type, only rosuvastatin resulted associated to a reduced risk of death (HR 0.88; 95%CI: 0.81; 0.96; p = 0.004). CONCLUSIONS: Statins use is significantly associated with a reduced risk of death in resected PDAC patients. This finding has to be considered with caution due to publication bias and the availability of only few studies for sensitivity analyses.

ABSTRACT: Pancreatic Neuroendocrine Neoplasms comprise a group of rare tumours with special biology, an often indolent behaviour and particular diagnostic and therapeutic requirements. The specialized biochemical tests and radiological investigations, the complexity of surgical options and the variety of medical treatments that require individual tailoring, mandate a multidisciplinary approach that can be optimally achieved through an organized network. The present study describes currents concepts in the management of these tumours as well as an insight into the challenges of delivering the pathway in and outside a Network.

3 Review How should incidental NEN of the pancreas and gastrointestinal tract be followed? 2018

Ariotti, Riccardo / Partelli, Stefano / Muffatti, Francesca / Andreasi, Valentina / Della Sala, Francesca / Falconi, Massimo. ·Pancreatic Surgery Unit, Pancreas Translational & Clinical Research Center, San Raffaele Scientific Institute, "Vita-Salute" University, Via Olgettina 60, 20132, Milan, Italy. · Pancreatic Surgery Unit, Pancreas Translational & Clinical Research Center, San Raffaele Scientific Institute, "Vita-Salute" University, Via Olgettina 60, 20132, Milan, Italy. falconi.massimo@hsr.it. ·Rev Endocr Metab Disord · Pubmed #29527619.

ABSTRACT: Neuroendocrine gastro-entero-pancreatic neoplasms (GEP-NENs) constitute a heterogeneous group of tumors, whose incidence has increased over the years. The most frequent site for primary disease is the stomach followed by small and large intestine, and pancreas. In the last decade, a dramatic growing in the incidence of small, incidental GEP-NENs has been recorded. In parallel, an increasing attitude toward more conservative approaches instead of surgical management has being widely spreading. This is particularly true for small, asymptomatic, pancreatic NEN as for these tumor forms an active surveillance has proven to be safe and feasible. Primary site and biological features of the neoplasms lead to different strategies and indications for surveillance and follow-up. This review focuses on the current evidence on modality and timing of surveillance and conservative treatment of incidentally discovered lesions.

ABSTRACT: BACKGROUND: Identification of factors associated with dismal survival after surgery in resectable pancreatic ductal adenocarcinoma is important to select patients for neoadjuvant treatment. The present meta-analysis aimed to compare the results of distal pancreatectomy for resectable adenocarcinoma of the pancreatic body-tail with and without splenic vessels infiltration. METHODS: A systematic search was performed of PubMed, Embase and the Cochrane Library in accordance with PRISMA guidelines. The inclusion criteria were studies including patients who underwent distal pancreatectomy for pancreatic cancer with or without splenic vessels infiltration. 5-year overall survival (OS) was the primary outcomes. Meta-analysis was carried out applying time-to-event method. RESULTS: Six articles with 423 patients were analysed. Patients with pathological splenic artery invasion had a worse survival compared with those without infiltration (Hazard ratio 1.76, 95% CI 1.36-2.28; P < 0.0001). A similar results was found when considering pathological splenic vessels infiltration, showing that survival was significantly poorer when splenic vein infiltration was present (Hazard ratio 1.51, 95% CI 1.19-1.93; P = 0.0009). CONCLUSIONS: This meta-analysis showed worse survival for patients with splenic vessels infiltration undergoing distal pancreatectomy for pancreatic cancer. Splenic vessels infiltration represents the stigmata of a more aggressive disease, although resectable.

ABSTRACT: After a timing preoperative staging, treatment of resectable pancreatic adenocarcinoma (PDAC) includes surgery and adjuvant therapies, the former representing the initial therapeutic option and the latter aiming to reduce the incidence of both distant metastases (chemotherapy) and locoregional failures (chemoradiotherapy). Herein, we provide a critical overview on the role of multimodal treatment in PDAC and on new opportunities related to current more active poli-chemotherapy regimens, targeted therapies, and the more recent immunotherapy approaches. Moreover, an analysis of pathological markers and clinical features able to help clinicians in the selection of the best therapeutic strategy will be discussed. Lastly, the role of neoadjuvant treatment of initially resectable disease will be considered mostly in patients whose malignancy shows morphological but not clinical or biological criteria of resectability. Depending on the results of these investigational studies, today a multidisciplinary approach can offer the best address therapy for these patients.

ABSTRACT: INTRODUCTION: The safety of laparoscopic resections (LPS) of pancreatic neuroendocrine neoplasms (PNENs) has been well established in the literature. Areas covered: Studies conducted between January 2003 and December 2015 that reported on LPS and open surgery (OPS) were reviewed. The primary outcomes were the rate of post-operative complications and the length of hospital stay (LoS) after laparoscopic and open surgical resection. The rate of recurrence was the secondary outcome. Eleven studies were included with a total of 907 pancreatic resections for PNENs, of whom, 298 (32.8%) underwent LPS and 609 (67.2%) underwent open surgery. LPS resulted in a significantly shorter LoS (p < 0.0001) and lower blood loss (p < 0.0001). The meta-analysis did not show any significant difference in the pancreatic fistula rate, recurrence rate or post-operative mortality between the two groups. Expert commentary: LPS is a safe approach even for PNENs and it is associated with a shorter LoS.

7 Review Systematic review of active surveillance versus surgical management of asymptomatic small non-functioning pancreatic neuroendocrine neoplasms. 2017

Partelli, S / Cirocchi, R / Crippa, S / Cardinali, L / Fendrich, V / Bartsch, D K / Falconi, M. ·Pancreatic Surgery Unit, Pancreas Translational and Clinical Research Centre, San Raffaele Scientific Institute, 'Vita-Salute' University, Milan, Italy. · Department of Digestive and Liver Surgery Unit, St Maria Hospital, Terni, Italy. · Department of Surgery, Polytechnic University of Marche Region, Ancona, Italy. · Department of Visceral, Thoracic and Vascular Surgery, Philipps-University Marburg, Marburg, Germany. ·Br J Surg · Pubmed #27706803.

ABSTRACT: BACKGROUND: The incidence of asymptomatic, sporadic, small non-functioning pancreatic neuroendocrine neoplasms (NF-PNENs) has increased in recent decades. Conservative treatment has been advocated for these tumours. The aim of this study was systematically to evaluate the literature on active surveillance and to compare this with surgical management for asymptomatic sporadic small NF-PNENs. METHODS: PubMed, Embase and the Cochrane Library were searched systematically for studies that compared the active surveillance of asymptomatic, sporadic, small NF-PNENs with surgical management. PRISMA guidelines for systematic reviews were followed. RESULTS: After screening 3915 records, five retrospective studies with a total of 540 patients were included. Of these, 327 patients (60·6 per cent) underwent active surveillance and 213 (39·4 per cent) had surgery. There was wide variation in the tumour diameter threshold considered as inclusion criterion (2 cm to any size). The median length of follow-up ranged from 28 to 45 months. Measurable tumour growth was observed in 0-51·0 per cent of patients. Overall, 46 patients (14·1 per cent) underwent pancreatic resection after initial conservative treatment. In most patients the reason was an increase in tumour size (19 of 46). There were no disease-related deaths in the active surveillance group in any of the studies. CONCLUSION: This systematic review suggests that active surveillance of patients affected by sporadic, small, asymptomatic NF-PNENs may be a good alternative to surgical treatment.

8 Review Management of neuroendocrine carcinomas of the pancreas (WHO G3): A tailored approach between proliferation and morphology. 2016

Crippa, Stefano / Partelli, Stefano / Belfiori, Giulio / Palucci, Marco / Muffatti, Francesca / Adamenko, Olga / Cardinali, Luca / Doglioni, Claudio / Zamboni, Giuseppe / Falconi, Massimo. ·Stefano Crippa, Stefano Partelli, Marco Palucci, Francesca Muffatti, Olga Adamenko, Massimo Falconi, Division of Pancreatic Surgery, Pancreas Translational and Clinical Research Center, San Raffaele Scientific Institute, Vita e Salute University, 20132 Milan, Italy. ·World J Gastroenterol · Pubmed #28018101.

ABSTRACT: Neuroendocrine carcinomas (NEC) of the pancreas are defined by a mitotic count > 20 mitoses/10 high power fields and/or Ki67 index > 20%, and included all the tumors previously classified as poorly differentiated endocrine carcinomas. These latter are aggressive malignancies with a high propensity for distant metastases and poor prognosis, and they can be further divided into small- and large-cell subtypes. However in the NEC category are included also neuroendocrine tumors with a well differentiated morphology but ki67 index > 20%. This category is associated with better prognosis and does not significantly respond to cisplatin-based chemotherapy, which represents the gold standard therapeutic approach for poorly differentiated NEC. In this review, the differences between well differentiated and poorly differentiated NEC are discussed considering both pathology, imaging features, treatment and prognostic implications. Diagnostic and therapeutic flowcharts are proposed. The need for a revision of current classification system is stressed being well differentiated NEC a more indolent disease compared to poorly differentiated tumors.

9 Review Enhanced recovery pathways in pancreatic surgery: State of the art. 2016

Pecorelli, Nicolò / Nobile, Sara / Partelli, Stefano / Cardinali, Luca / Crippa, Stefano / Balzano, Gianpaolo / Beretta, Luigi / Falconi, Massimo. ·Nicolò Pecorelli, Sara Nobile, Stefano Partelli, Stefano Crippa, Gianpaolo Balzano, Massimo Falconi, Division of Pancreatic Surgery, Pancreas Translational and Clinical Research Center, San Raffaele Scientific Institute, "Vita-Salute" University, 20132 Milan, Italy. ·World J Gastroenterol · Pubmed #27605881.

ABSTRACT: Pancreatic surgery is being offered to an increasing number of patients every year. Although postoperative outcomes have significantly improved in the last decades, even in high-volume centers patients still experience significant postoperative morbidity and full recovery after surgery takes longer than we think. In recent years, enhanced recovery pathways incorporating a large number of evidence-based perioperative interventions have proved to be beneficial in terms of improved postoperative outcomes, and accelerated patient recovery in the context of gastrointestinal, genitourinary and orthopedic surgery. The role of these pathways for pancreatic surgery is still unclear as high-quality randomized controlled trials are lacking. To date, non-randomized studies have shown that care pathways for pancreaticoduodenectomy and distal pancreatectomy are safe with no difference in postoperative morbidity, leading to early discharge and no increase in hospital readmissions. Hospital costs are reduced due to better organization of care and resource utilization. However, further research is needed to clarify the effect of enhanced recovery pathways on patient recovery and post-discharge outcomes following pancreatic resection. Future studies should be prospective and follow recent recommendations for the design and reporting of enhanced recovery pathways.

ABSTRACT: BACKGROUND: Preoperative biliary drainage (PBD) with stenting increases complications compared with surgery without PBD. Metallic stents are considered superior to plastic stents when considering stent-related complications. Aim of the present systematic review and meta-analysis is to compare the rate of endoscopic re-intervention before surgery and postoperative outcomes of metal versus plastic stents in patients with resectable periampullary or pancreatic head neoplasms. METHODS: We conducted a bibliographic research using the National Library of Medicine's PubMed database, including both randomized controlled trials (RCTs) and non-RCTs. Quantitative synthesis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Statistical heterogeneity was assessed using the I(2) tests. RESULTS: One RCT and four non-RCTs were selected, including 704 patients. Of these, 202 patients (29.5%) were treated with metal stents and 502 (70.5%) with plastic stents. The majority of patients (86.4%) had pancreatic cancer. The rate of endoscopic re-intervention after preoperative biliary drainage was significantly lower in the metal stent (3.4%) than in the plastic stent (14.8%) group (p < 0.0001). The rate of postoperative pancreatic fistula was significantly lower in the meta stent group as well (5.1% versus 11.8%, p = 0.04). The rate of post-operative surgical complications and of - post-operative mortality did not differ between the two groups. CONCLUSIONS: Although the present systematic review and meta-analysis demonstrates that metal stent are more effective than plastic stents for PBD in patients with resectable periampullary tumors, randomized controlled trials are needed in order to confirm these data with a higher level of evidence.

ABSTRACT: During the last decades an increase in the incidence of neuroendocrine tumors (NETs) was observed. Gastroenteropancreatic NETs represent the majority of NETs. Compared with their epithelial counterpart they usually have a more indolent behaviour and surgical resection improves survival. Tumor diameter is one of the main parameter in the decision making process for nonfunctioning forms. Generally, small lesions can be treated conservatively whereas larger tumors should be treated with standard surgical resection and lymphadenectomy. Functioning tumors should be resected regardless the dimension of the lesion. Locally advanced and metastatic disease should be also treated with extended resections, keeping in consideration the grading, size, Ki67, and presence of extra-abdominal disease. In the case of metastases the panel of operative treatment includes resection, ablation, up to liver transplantation.

12 Review Ki-67 prognostic and therapeutic decision driven marker for pancreatic neuroendocrine neoplasms (PNENs): A systematic review. 2016

Electronic address: falconi.massimo@hsr.it. ·Adv Med Sci · Pubmed #26774266.

ABSTRACT: BACKGROUND: We systematically evaluate the current evidence regarding Ki-67 as a prognostic factor in pancreatic neuroendocrine neoplasms to evaluate the differences of this marker in primary tumors and in distant metastases as well as the values of Ki-67 obtained by fine needle aspiration and by histology. METHODS: The literature search was carried out using the MEDLINE/PubMed database, and only papers published in the last 10 years were selected. RESULTS: The pancreatic tissue suitable for Ki-67 evaluation was obtained from surgical specimens in the majority of the studies. There was a concordance of 83% between preoperative and postoperative Ki-67 evaluation. Pooling the data of the studies which compared the Ki-67 values obtained in both cytological and surgical specimens, we found that they were not related. The assessment of Ki-67 was manual in the majority of the papers considered for this review. In order to eliminate manual counting, several imaging methods have been developed but none of them are routinely used at present. Twenty-two studies also explored the role of Ki-67 utilized as a prognostic marker for pancreatic neuroendocrine neoplasms and the majority of them showed that Ki-67 is a good prognostic marker of disease progression. Three studies explored the Ki-67 value in metastatic sites and one study demonstrated that, in metachronous and synchronous liver metastases, there was no significant variation in the index of proliferation. CONCLUSIONS: Ki-67 is a reliable prognostic marker for pancreatic neuroendocrine neoplasms.

ABSTRACT: Treatment of pancreatic ductal adenocarcinoma (PDAC) is increasingly multidisciplinary, with neoadjuvant strategies (chemotherapy, radiation, and surgery) administered in patients with resectable, borderline resectable, or locally advanced disease. The rational supporting this management is the achievement of both higher margin-negative resections and conversion rates into potentially resectable disease and in vivo assessment of novel therapeutics. International guidelines suggest an initial staging of the disease followed by a multidisciplinary approach, even considering the lack of a treatment approach to be considered as standard in this setting. This review will focus on both literature data supporting these guidelines and on new opportunities related to current more active chemotherapy regimens. An analysis of the pathological assessment of response to therapy and the potential role of target therapies and translational biomarkers and ongoing clinical trials of significance will be discussed.

14 Review Pancreatic Surgery. 2015

Maurizi, Angela / Partelli, Stefano / Falconi, Massimo. ·Pancreatic Surgery Unit, AOUI Ospedali Riuniti - Università Politecnica delle Marche, Ancona, Italy. ·Front Horm Res · Pubmed #26303709.

ABSTRACT: Pancreatic neuroendocrine tumors (pNETs) are rare and clinically demanding diseases. They are clinically defined as functioning or nonfunctioning depending on the presence of a syndrome related to inappropriate hormone secretion. Functioning pNETs are often small in size and localization may be difficult also due to their possible extraduodenal-pancreatic origin in the jejunum, stomach, mesentery, spleen and ovaries. The improvement and the widespread use of cross-sectional imaging techniques has significantly increased the detection of small, nonfunctioning pNETs. The European Neuroendocrine Tumor Society (ENETS) guidelines now suggest a 'wait and see' policy for these small, incidentally discovered tumors, which are smaller than 2 cm. On the other hand, surgery still always represents the treatment of choice for pNETs >2 cm and/or for symptoms. A large proportion of patients with pNETs have locally advanced disease at diagnosis. Radical surgery of pNETs includes both typical and atypical pancreatic resections. At diagnosis, between 25 and 93% of patients with pNETs have synchronous neuroendocrine tumor liver metastases. Radical resection of the primary tumor, associated with complete, eventually multistep, resection of the liver metastases, can be considered in selected cases. In recent years minimally invasive approaches, either laparoscopic or robotic, have played an increasing role in the treatment of pNETs.

15 Review Selection criteria in resectable pancreatic cancer: a biological and morphological approach. 2014

Tamburrino, Domenico / Partelli, Stefano / Crippa, Stefano / Manzoni, Alberto / Maurizi, Angela / Falconi, Massimo. ·Domenico Tamburrino, Stefano Partelli, Stefano Crippa, Alberto Manzoni, Angela Maurizi, Massimo Falconi, Pancreatic Surgery Unit, Department of Surgery, Polytechnic University of Marche Region, 60126 Ancona-Torrette, Italy. ·World J Gastroenterol · Pubmed #25170205.

ABSTRACT: Pancreatic ductal adenocarcinoma (PDA) remains one of the most aggressive tumors with a low rate of survival. Surgery is the only curative treatment for PDA, although only 20% of patients are resectable at diagnosis. During the last decade there was an improvement in survival in patients affected by PDA, possibly explained by the advances in cancer therapy and by improve patient selection by pancreatic surgeons. It is necessary to select patients not only on the basis of surgical resectability, but also on the basis of the biological nature of the tumor. Specific preoperative criteria can be identified in order to select patients who will benefit from surgical resection. Duration of symptoms and level of carbohydrate antigen 19.9 in resectable disease should be considered to avoid R1 resection and early relapse. Radiological assessment can help surgeons to distinguish resectable disease from borderline resectable disease and locally advanced pancreatic cancer. Better patient selection can increase survival rate and neoadjuvant treatment can help surgeons select patients who will benefit from surgery.

ABSTRACT: Since the first description of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas in the eighties, their identification has dramatically increased in the last decades, hand to hand with the improvements in diagnostic imaging and sampling techniques for the study of pancreatic diseases. However, the heterogeneity of IPMNs and their malignant potential make difficult the management of these lesions. The objective of this review is to identify the molecular characteristics of IPMNs in order to recognize potential markers for the discrimination of more aggressive IPMNs requiring surgical resection from benign IPMNs that could be observed. We briefly summarize recent research findings on the genetics and epigenetics of intraductal papillary mucinous neoplasms, identifying some genes, molecular mechanisms and cellular signaling pathways correlated to the pathogenesis of IPMNs and their progression to malignancy. The knowledge of molecular biology of IPMNs has impressively developed over the last few years. A great amount of genes functioning as oncogenes or tumor suppressor genes have been identified, in pancreatic juice or in blood or in the samples from the pancreatic resections, but further researches are required to use these informations for clinical intent, in order to better define the natural history of these diseases and to improve their management.

ABSTRACT: The incidence of neuroendocrine tumors (NETs) has increased in the last decades. Surgical treatment encompasses a panel of approaches ranging from conservative procedures to extended surgical resection. Tumor size and localization usually represent the main drivers in the choice of the most appropriate surgical resection. In the presence of small (<2 cm) and asymptomatic nonfunctioning NETs, a conservative treatment is usually recommended. For localized NETs measuring above 2 cm, surgical resection represents the cornerstone in the management of these tumors. As they are relatively biologically indolent, an extended resection is often justified also in the presence of advanced NETs. Surgical options for NET liver metastases range from limited resection up to liver transplantation. Surgical choices for metastatic NETs need to consider the extent of disease, the grade of tumor, and the presence of extra-abdominal disease. Any surgical procedures should always be balanced with the benefit of survival or relieving symptoms and patients' comorbidities.

ABSTRACT: INTRODUCTION: Pancreatic or duodenal invasion by locally advanced right colon cancer is an unusual event whose management still represents a surgical challenge. This review aims to compare results of limited vs. extended resection in case of primary right colon cancer invading pancreas and/or duodenum. METHODS: A systematic search in Medline, Embase and Cochrane Central Register of Controlled Trials (CENTRAL) was performed. All trials describing the surgical treatment of right colon cancer invading pancreas and/or duodenum were considered. A data extraction sheet was developed, based on the Cochrane Consumers and Communication Review Group's data extraction template. RESULTS: 5-years overall survival was 52% after en bloc pancreaticoduodenectomy plus right hemicolectomy vs. 0 and 25% in case of duodenal resection with correction by direct suture or pedicled ileal flap, respectively. 30-day postoperative morbidity rate was slightly higher after en block resections (12.8%) with respect to duodenal local resection and direct suture or pedicled ileal flap repair (0 and 12.2%, respectively). After extended resection the rate of pancreatico-jejunal anastomotic leakage was 7.7%. CONCLUSIONS: In patients with right colon cancer extended to the pancreas and/or duodenum surgical multivisceral resection is suggested when complete tumour removal (R0) is achievable. Even though no significant differences in postoperative morbidity and mortality have been shown, 5 y OS has improved in extended resections as compared to duodenal local resection with defect repair either by direct suture or by a pedicled ileal flap.

19 Review Surgical management of pancreatic neuroendocrine neoplasms. 2014

ABSTRACT: Pancreatic neuroendocrine neoplasms are relatively rare entities, representing approximately 1% to 2% of all pancreatic tumors. Owing to their rarity as well as their relatively indolent natural history, treatment approaches are not yet standardized. A formal pancreatic resection is usually mandatory for large and localized sporadic pancreatic tumors or in the presence of symptoms. However, in small and asymptomatic lesions, a conservative approach consisting in a careful wait-and-see policy is going to appear as more appropriate, particularly when, to remove the lesion, an aggressive surgical procedure is required, such as pancreaticoduodenectomy or distal splenopancreatectomy, depending on the localization of the tumor. Surgery has also a significant role in locally advanced and metastatic forms. In the setting of MEN 1 syndrome or Von-Hippel Lindau disease, the tumor size and the possible symptoms should be considered in the evaluation of a proper treatment.

20 Review A systematic review on robotic pancreaticoduodenectomy. 2013

ABSTRACT: BACKGROUND: Robotic surgery might have several advantages in respect of the laparoscopic approach since might make more feasible the execution of a complex procedure such as pancreaticoduodenectomy (PD). The aim of the present systematic review is to evaluate the current state of the literature on robotic PD. METHODS: A systematic literature search was performed, from January 1st 2003 to July 31st 2012, for studies which reported PDs performed for neoplasm and in which at least one surgical reconstructive or resective step was robotically performed. RESULTS: Thirteen studies, representing 207 patients, met the inclusion criteria. The definition of the robotic approach was heterogeneous since the technique was defined as robotic, robotic-assisted, robot-assisted laparoscopic and robotic hybrid. Resection and reconstruction steps of robotic PD were also heterogeneous combining sequentially different approaches: totally robotic technique, laparoscopic-robotic resection and robotic reconstruction, laparoscopic resection and robotic reconstruction, hand port-assisted laparoscopic resection and robotic reconstruction, laparoscopic-robotic resection and reconstruction through mini-laparotomy. As regard the type of PD 66% were classic Whipple operations and 34% pylorus-preserving pancreatoduodenectomies. The management of pancreatic stump was a pancreaticogastrostomy in 23%, end-to-side pancreaticojejunostomy in 67%, and fibrin glue occlusion of the main pancreatic duct in 10% of cases. The overall procedure failure (rates of conversion to open surgery) was 14%. The overall morbidity rate was 58% and the reoperation rate was 7.3%. CONCLUSIONS: There have been an increasing number of recent case series suggesting increased utilization of robotic PD over the past decade. The technical approach is heterogenous. For highly selected patient, robotic PD is feasible with similar morbidity and mortality compared to open or purely laparoscopic approaches. Data on cost analysis are lacking and further studies are needed to evaluate also the cost-effectiveness of the robotic approach for PD in comparison to open or laparoscopic techniques. The current state of the art analysis on robotic DP can be also useful in planning future trials.

21 Review Current status of robotic distal pancreatectomy: a systematic review. 2013

ABSTRACT: OBJECTIVE: The aim of this systematic review is to determine the potential advantages of robotic distal pancreatectomy (RDP). STUDY SELECTION: Both randomized and non-randomized studies. DATA EXTRACTION: Two investigators independently selected studies for inclusion by article abstraction and full text reviewing. DATA SYNTHESIS: Five non-RCTs were included in the review. The feasibility of RDP (95.4%) and spleen-preserving rate is between 50% and 100%. Mean OT varied between 298 min and 398 min with only completely robotic procedures, whereas mean OT was 293 in "laparoscopic/robotic" technique. Postoperative length of hospital stay ranged from 7 days to 13.7 days. The 30-day postoperative overall morbidity resulted between 0 and 18% of patients. CONCLUSIONS: RDP is an emergent technology for which there are not yet sufficient data to draw definitive conclusions with respect to conventional or laparoscopic surgery. The mean duration of RDP is longer with Da Vinci robot, but hospital stay is shorter even if it is influenced by hospital protocols. We cannot make any conclusions comparing the outcomes to laparoscopic or open procedures here, since none of these studies are randomized, and we all know that most of these surgeons selected the easier cases for robotic procedures. For these reasons randomized controlled trials are recommended to better evaluate RDP cost-effectiveness.

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

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.

ABSTRACT: BACKGROUND: The current trial assessed whether the addition of cisplatin and capecitabine to the nab-paclitaxel-gemcitabine backbone is feasible and active against borderline and locally advanced pancreatic adenocarcinoma (PDAC). METHOD: Fifty-four chemo-naive patients, aged between 18 and 75 years, with a pathological diagnosis of locally advanced or borderline resectable PDAC were randomised to receive either nab-paclitaxel, gemcitabine, cisplatin and oral capecitabine (PAXG; arm A; N = 26) or nab-paclitaxel followed by gemcitabine (AG; arm B; N = 28). The primary end-point was the tumour resection rate. If at least four such resections were performed, the treatment was considered as active. The secondary end-points were progression-free survival (PFS), overall survival (OS), Response Evaluation Criteria in Solid Tumours response rate, Hartman's pathologic response, carbohydrate antigen 19.9 response rate and toxicity. RESULTS: Eight patients (31%) in the PAXG arm and nine (32%) in the AG arm underwent resection. PFS at 1-year was 58% in arm A and 39% in arm B. OS at 18-month was 69% in arm A and 54% in arm B. CONCLUSIONS: In this phase II study, the addition of cisplatin and capecitabine to the AG backbone was feasible and yielded promising results in terms of disease control without detrimental impact on tolerability. The approach warrants further investigation in a phase III study. TRIAL REGISTRATION: NCT01730222.

ABSTRACT: BACKGROUND: The possible benefit of frozen section (FS) analysis during (PD) for pancreatic ductal adenocarcinoma (PDAC) and of additional resection up to total pancreatectomy (TP) is debated. Aim of this work is to evaluate the prognostic role of positive FS analysis after PD for PDAC. METHODS: Multicentric retrospective analysis on prospective databases of three institutions. Based on FS analysis patients were classified as FS negative/FS positive. All positive FS patients underwent extended PD (EPD) or TP. Postoperative outcomes, disease-free (DFS) and disease-specific survival (DSS) were evaluated. RESULTS: Of 371 patients, 58 (16%) had positive FS. This resulted in 313 (84%) SPD (standard pancreatoduodenectomy), 22 (6%) EPD and 36 (10%) TP. Postoperative mortality was higher in patients undergoing TP (11% compared to 4.5% in EPD and 1% in SPD; p = 0.01). 26% of patients underwent neoadjuvant therapy, and it did not decrease the rate of positive FS. Systemic/local relapse rates were 59% and 41% in negative FS group, and 78% and 22% in positive FS group (p = 0.031). Median DFS and DSS were 20 and 37 months in negative FS group, and 12 and 23 months in positive FS patients (p = 0.001). Independent predictors of recurrence were G3, N1/N2 status and positive FS. R1 resection, G3, N1/N2 status, perineural invasion and positive FS were independent predictors of DSS. CONCLUSIONS: Positive FS analysis is a poor prognostic factor after PD for PDAC. It is significantly associated with a high rate of R1 resection at final histology, PDAC recurrence and poor survival.

ABSTRACT: Recent studies considered surgery as a treatment option for patients with pancreatic ductal adenocarcinoma (PDAC) and synchronous liver metastases. The aim of this study was to evaluate systematically the literature on the role of surgical resection in this setting as an upfront procedure or following primary chemotherapy. A systematic search was performed of PubMed, Embase and the Cochrane Library in accordance with PRISMA guidelines. Only studies that included patients with synchronous liver metastases published in the era of multiagent chemotherapy (after 2011) were considered, excluding those with lung/peritoneal metastases or metachronous liver metastases. Median overall survival (OS) was the primary outcome. Six studies with 204 patients were analyzed. 63% of patients underwent upfront pancreatic and liver resection, 35% had surgery after primary chemotherapy with strict selection criteria and 2% had an inverse approach (liver surgery first). 38 patients (18.5%) did not undergo any liver resection since metastases disappeared after chemotherapy. Postoperative mortality was low (< 2%). Median OS ranged from 7.6 to 14.5 months after upfront pancreatic/liver resection and from 34 to 56 months in those undergoing preoperative treatment. This systematic review suggests that surgical resection of pancreatic cancer with synchronous liver oligometastases is safe, and it can be associated with improved survival, providing a careful selection of patients after primary chemotherapy.
