Surgeon Perspectives on the Management of Aborted Cancer Surgery: Results of a Society of Surgical Oncology Member Survey. Ann Surg Oncol 2024; 31:2295-2302. [PMID: 38127216 DOI: 10.1245/s10434-023-14804-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Accepted: 12/06/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND While surgery is generally necessary for most solid-organ cancers, curative-intent resection is occasionally aborted due to unanticipated unresectability or occult metastases. Following aborted cancer surgery (ACS), patients have unique and complex care needs and yet little is known about the optimal approach to their management. OBJECTIVE The aim of this study was to define the practice patterns and perspectives of an international cohort of cancer surgeons on the management of ACS. METHODS A validated survey assessing surgeon perspectives on patient care needs and management following ACS was developed. The survey was distributed electronically to members of the Society of Surgical Oncology (SSO). RESULTS Among 190 participating surgeons, mean age was 49 ± 11 years, 69% were male, 61% worked at an academic institution, and most had a clinical practice focused on liver/pancreas (30%), breast (23%), or melanoma/sarcoma cancers (20%). Participants estimated that ACS occurred in 7 ± 6% of their cancer operations, most often due to occult metastases (67%) or local unresectability (30%). Most surgeons felt (very) comfortable addressing their patients' surgical needs (92%) and cancer treatment-related questions (90%), but fewer expressed comfort addressing psychosocial needs (83%) or symptom-control needs (69%). While they perceived discussing next available therapies as the patients' most important priority after ACS, surgeons reported avoiding postoperative complications as their most important priority (p < 0.001). While 61% and 27% reported utilizing palliative care and psychosocial oncology, respectively, in these situations, 46% noted care coordination as a barrier to addressing patient care needs. CONCLUSIONS Results from this SSO member survey suggest that ACS is relatively common and associated with unique patient care needs. Surgeons may feel less comfortable assessing psychosocial and symptom-control needs, highlighting the need for novel patient-centered approaches.

Evaluating staging laparoscopy indications for pancreatic cancer based on resectability classification and treatment strategies for patients with positive peritoneal washing cytology. Ann Gastroenterol Surg 2024; 8:124-132. [PMID: 38250680 PMCID: PMC10797817 DOI: 10.1002/ags3.12719] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 06/17/2023] [Accepted: 07/04/2023] [Indexed: 01/23/2024] Open
Abstract
Introduction The prognosis of pancreatic ductal adenocarcinoma (PDAC) in patients with positive peritoneal washing cytology (CY1) is poor. We aimed to evaluate the results of staging laparoscopy (SL) and treatment efficacy in CY1 patients based on a resectability classification. Methods We retrospectively reviewed 250 patients with PDAC who underwent SL before the initial treatment between 2017 and 2023 at the University of Toyama. Results The breakdown of cases by resectability classification was resectable (R):borderline resectable (BR):unresectable locally advanced (UR-LA) = 131:48:71 cases. The frequency of CY1 increased in proportion to the degree of local progression (R:BR:UR-LA = 20:23:34%), but the frequencies of liver metastasis or peritoneal dissemination were comparable (R:BR:UR-LA = 6.9:6.3:8.5%). Most CY1 patients received gemcitabine along with nab-paclitaxel therapy. The CY-negative conversion rates (R:BR:UR-LA = 70:64:52%) and conversion surgery rates (R:BR:UR-LA = 40:27:9%) were inversely proportional to the degree of local progression.Comparing H0P0CY1 factors for each classification, patients with H0P0CY1 had significantly more pancreatic body or tail carcinoma and tumor size ≥32 mm in R patients, whereas in BR patients, duke pancreatic monoclonal antigen type 2 (DUPAN-2) ≥ 230 U/mL was a significant factor. In contrast, no significant factors were observed in UR-LA patients. Conclusion The CY1 rates, CY-negative conversion rates, and conversion surgery rates varied according to local progression. In the case of R and BR, SL could be considered in patients with pancreatic body or tail carcinoma, large tumor size, or high DUPAN-2 level. In UR-LA, SL might be considered for all patients.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is a challenging disease process with a 5-year survival rate of only 11%. Neoadjuvant therapy in patients with localized pancreatic cancer has multiple theoretical benefits, including improved patient selection for surgery, early delivery of systemic therapy, and assessment of response to therapy. Herein, we review key surgical considerations when selecting patients for neoadjuvant therapy and curative-intent resection. Accurate determination of resectability at diagnosis is critical and should be based on not only anatomic criteria but also biologic and clinical criteria to determine optimal treatment sequencing. Borderline resectable or locally advanced pancreatic cancer is best treated with neoadjuvant therapy and resection, including vascular resection and reconstruction when appropriate. Lastly, providing nutritional, prehabilitation, and supportive care interventions to improve patient fitness prior to surgical intervention and adequately address the adverse effects of therapy is critical.

Abstract
BACKGROUND Patients with pancreas cancer may undergo palliative gastrointestinal or biliary bypass. Recent comparisons of post-operative outcomes following such procedures are lacking. METHODS We analyzed patients undergoing exploration, gastrojejunostomy, biliary bypass or double bypass for pancreatic cancer using data from the 2005-2019 American College of Surgeons National Surgical Quality Improvement Program. We compared 30-day mortality and complications across procedures and over time periods (2005-10, 2011-14, 2015-19) using multivariable regression models. Factors associated with postoperative mortality were identified. RESULTS Of 43,525 patients undergoing surgery with a postoperative diagnosis of pancreatic cancer, 5572 met inclusion criteria. Palliative operations included 1037 gastrojejunostomies, 792 biliary bypasses, 650 double bypasses, and 3093 explorations. The proportion of biliary and double bypass procedures decreased from 2005-10 to 2015-19. Gastrojejunostomy had higher 30-day mortality rate (11.5%) than other operations (p < 0.001). Adjusted 30-day mortality rates remained stable over time (7.8% vs 6.3%, p = 0.095), while rates of serious complications decreased over time (23.2% vs 17.1%, p < 0.001). CONCLUSIONS Palliative bypass for pancreatic cancer has not become safer over time, and 30-day mortality and complications remain high.

Comparisons of short-term and long-term results between laparoscopic between open pancreaticoduodenectomy for pancreatic tumors: A systematic review and meta-analysis. Front Genet 2023; 13:1072229. [PMID: 36744174 PMCID: PMC9894883 DOI: 10.3389/fgene.2022.1072229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 12/07/2022] [Indexed: 01/22/2023] Open
Abstract
Objective: The efficacy of pancreaticoduodenectomy and open pancreaticoduodenectomy for pancreatic tumors is controversial. The study aims to compare the efficacy of laparoscopic pancreaticoduodenectomy (LPD) and open pancreaticoduodenectomy (OPD) in the treatment of pancreatic tumors through systematic evaluation and meta-analysis. Methods: PubMed, Embase, Cochrane Library and Web of science databases were searched for clinical studies on the treatment of pancreatic tumors with LPD and OPD. The end time for the searches was 20 July 2022. Rigorous inclusion and exclusion criteria were used to screen the articles, the Cochrane manual was used to evaluate the quality of the included articles, and the stata15.0 software was used for statistical analysis of the indicators. Results: In total, 16 articles were included, including two randomized controlled trials and 14 retrospective studies. Involving a total of 4416 patients, 1275 patients were included in the LPD group and 3141 patients in the OPD group. The results of the meta-analysis showed that: the operation time of LPD was longer than that of OPD [WMD = 56.14,95% CI (38.39,73.89), p = 0.001]; the amount of intraoperative blood loss of LPD was less than that of OPD [WMD = -120.82,95% CI (-169.33, -72.30), p = 0.001]. No significant difference was observed between LPD and OPD regarding hospitalization time [WMD = -0.5,95% CI (-1.35, 0.35), p = 0.250]. No significant difference was observed regarding postoperative complications [RR = 0.96,95% CI (0.86,1.07, p = 0.463]. And there was no significant difference regarding 1-year OS and 3-year OS: 1-year OS [RR = 1.02,95% CI (0.97,1.08), p = 0.417], 3-year OS [RR = 1.10 95% CI (0.75, 1.62), p = 0.614%]. Conclusion: In comparison with OPD, LPD leads to less blood loss but longer operation time, therefore the bleeding rate per unit time of LPD is less than that of OPD. LPD has obvious advantages. With the increase of clinical application of LPD, the usage of LPD in patients with pancreatic cancer has very good prospect. Due to the limitations of this paper, in future studies, more attention should be paid to high-quality, multi-center, randomized controlled studies.

Abstract
Pancreatic cancer is the eighth most common cancer and the fifth most common cause of cancer-related deaths in Korea. Despite the increasing incidence and high mortality rate of pancreatic cancer, there are no appropriate surgical practice guidelines for the current domestic medical situation. To enable standardization of management and facilitate improvements in surgical outcome, a total of 10 pancreatic surgical experts who are members of Korean Association of Hepato-Biliary-Pancreatic Surgery have developed new recommendations that integrate the most up-to-date, evidence-based research findings and expert opinions. This is an English version of the Korean Surgical Practice Guideline for Pancreatic Cancer 2021. This guideline includes 13 surgical questions and 15 statements. Due to the lack of high-level evidence, strong recommendation is almost impossible. However, we believe that this guideline will help surgeons understand the current status of evidence and suggest what to investigate further to establish more solid recommendations in the future.

Abstract
BACKGROUND For patients with periampullary adenocarcinoma (PAC), pancreatoduodenectomy (PD) provides the best survival. Surgery on a subset of patients is aborted during PD. We analyzed these patients. METHODS Patients who underwent laparotomy for planned PD for PAC were identified (2006-2019). From operative notes, we identified the subset with intraoperative decision to abort. Patient, treatment, and outcome data were analyzed. The subset with pancreatic ductal adenocarcinoma (PDAC) was analyzed for survival. RESULTS Only 6.7% (n = 55/819) of cases were aborted. Majority 78% (n = 43) had pathologically-confirmed diagnoses at time of surgery, and 18.2% (n = 10) received preoperative chemotherapy. Reasons for aborted PD included: distant metastases (65.5%, n = 36) and local invasion (34.5%, n = 19). Of patients with metastatic disease, 75% (n = 27) had liver metastases. Eighty-nine percent (n = 49) of patients underwent at least one palliative bypass procedure and 81.8% (n = 45) had both gastric and biliary bypass. Patients with computed tomography (CT) scans before surgery more commonly had missed metastatic disease (79.2% CT compared to 54.8% magnetic resonance imaging [MRI], χ2 = 3.54, p = 0.059). In PDAC, 61.4% (n = 27/44) were aborted for metastatic disease and 38.7% (n = 17/44) for local invasion. Median overall survival for all PDAC patients after aborted PD was 334 days. CONCLUSION Majority of pancreatoduodenectomies for periampullary adenocarcinoma are done to completion. Liver metastases is the most common reason for aborting. Preoperative MRI may help identify hepatic metastases.

Abstract
Pancreatic cancer is the eighth most common cancer and the fifth most common cause of cancer-related death in Korea. To enable standardization of management and facilitate improvements in outcome, a total of 53 multi-disciplinary experts in gastroenterology, surgery, medical oncology, radiation oncology, radiology, nuclear medicine, and pathology in Korea developed new recommendations that integrate the most up-to-date, evidence-based research findings and expert opinions. Recommendations were made on imaging diagnosis, endoscopic management, surgery, radiotherapy, palliative chemotherapy, and specific management procedures, including neoadjuvant treatment or adjuvant treatment for patients with resectable, borderline resectable, and locally advanced unresectable pancreatic cancer. This is the English version of the Korean clinical practice guideline for pancreatic cancer 2021. This guideline includes 20 clinical questions and 32 statements. This guideline represents the most standard guideline for the diagnosis and treatment of patients with pancreatic ductal adenocarcinoma in adults at this time in Korea. The authors believe that this guideline will provide useful and informative advice.

Abstract
Pancreatic cancer is one of the solid tumors with the worst prognosis. Five-year survival rate is less than 10%. Surgical resection is the only potentially curative treatment, but the tumor is often diagnosed at an advanced stage of the disease and surgery could be performed in a very limited number of patients. Moreover, surgery is still associated with high post-operative morbidity, while other therapies still offer very disappointing results. This article reviews every aspect of pancreatic cancer, focusing on the elements that can improve prognosis. It was written with the aim of describing everything you need to know in 2021 in order to face this difficult challenge.

Determining the CA19-9 concentration that best predicts the presence of CT-occult unresectable features in patients with pancreatic cancer: A population-based analysis. Pancreatology 2020; 20:1458-1464. [PMID: 32868184 DOI: 10.1016/j.pan.2020.07.405] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2019] [Revised: 07/07/2020] [Accepted: 07/28/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND Serum CA19-9 concentration may be useful in triaging patients with pancreatic cancer for more intensive staging investigations. Our aim was to identify the CA19-9 cut-point with the greatest accuracy for detecting unresectable features not identified by CT scan, and to examine the performance of this and other cut-points in predicting the outcome of staging laparoscopy (SL). METHODS Patients with pancreatic cancer were drawn from two state-wide cancer registries between 2009 and 2011. We used classification and regression tree (CART) analysis to identify the CA19-9 cut-point which best predicted the presence of imaging-occult unresectable features, and compared its performance with that of a number of alternative cut-points. We then used logistic regression to test the association between CA19-9 concentration and detection of unresectable features in patients who underwent SL. RESULTS From the CART analysis, the optimal CA19-9 cut-point was 440 U/mL. CA19-9 ≥ 150 U/mL had a similar Youden Index, but greater sensitivity (69% versus 47%). This remained true for those who had obstructive jaundice at the time of CA19-9 sampling. CA19-9 concentration greater than or equal to 110 U/mL, 150 U/mL and 200 U/mL was associated with significantly greater odds of unresectable features being detected during SL. CONCLUSION Elevated serum CA19-9 concentration is a valid marker for CT-occult unresectable features; the most clinically appropriate cut-point appears to be ≥ 150 U/mL irrespective of the presence of jaundice. Clinical trials which evaluate the value of CA19-9 in the staging algorithm for pancreatic cancer are needed before it is routinely used in clinical practice.

Abstract
Pancreatic cancer is a highly fatal disease with a 5-year survival rate of approximately 10% in the USA, and it is becoming an increasingly common cause of cancer mortality. Risk factors for developing pancreatic cancer include family history, obesity, type 2 diabetes, and tobacco use. Patients typically present with advanced disease due to lack of or vague symptoms when the cancer is still localised. High quality computed tomography with intravenous contrast using a dual phase pancreatic protocol is typically the best method to detect a pancreatic tumour and to determine surgical resectability. Endoscopic ultrasound is an increasingly used complementary staging modality which also allows for diagnostic confirmation when combined with fine needle aspiration. Patients with pancreatic cancer are often divided into one of four categories based on extent of disease: resectable, borderline resectable, locally advanced, and metastatic; patient condition is also an important consideration. Surgical resection represents the only chance for cure, and advancements in adjuvant chemotherapy have improved long-term outcomes in these patients. Systemic chemotherapy combinations including FOLFIRINOX (5-fluorouracil, folinic acid [leucovorin], irinotecan, and oxaliplatin) and gemcitabine plus nab-paclitaxel remain the mainstay of treatment for patients with advanced disease. Data on the benefit of PARP inhibition as maintenance therapy in patients with germline BRCA1 or BRACA2 mutations might prove to be a harbinger of advancement in targeted therapy. Additional research efforts are focusing on modulating the pancreatic tumour microenvironment to enhance the efficacy of the immunotherapeutic strategies.

Abstract
OBJECTIVE The purpose of this study was to evaluate the performance of systematic MRI with DWI for the detection of liver metastases (LM) in patients with potentially resectable pancreatic ductal carcinoma and normal liver findings at CT. SUBJECTS AND METHODS Patients with potentially resectable pancreatic ductal carcinoma and a normal liver at CT were enrolled in a prospective multicenter study between March 2011 and July 2013 and underwent preoperative MRI. The reference standard was pathologic analysis of detected hepatic lesions. RESULTS A total of 118 patients were enrolled. MRI depicted liver lesions that were not visible at CT in 16 patients. All lesions were visualized both with and without DWI. Lesions were LM in 12 (10.2%) patients and were confirmed in seven patients by preoperative biopsy, four by intraoperative frozen section, and one at 6-month follow-up evaluation after pancreatic resection. All but one liver metastatic lesion diagnosed with MRI were smaller than 10 mm. Four of 118 (3.4%) patients had a false-positive diagnosis of LM at MRI and remained LM free after a follow-up period of 24 months or longer. Three of 102 (2.9%) patients with normal MRI findings had subcapsular LM that were diagnosed intraoperatively. At follow-up, 99 of 118 (83.9%) patients were LM free after a mean of 24 months. The patient-based sensitivity of MRI for the detection of LM was 80.0% (95% CI, 51.9-95.7%); specificity, 96.1% (95% CI, 90.4-98.9%); positive predictive value, 75.0% (95% CI, 47.6-92.7%); and negative predictive value, 97.1% (95% CI, 91.6-99.4%). CONCLUSION Compared with CT, preoperative MRI improves the detection of LM in patients with potentially resectable pancreatic ductal carcinoma and may change management and the rate of unnecessary laparotomy and pancreatectomy for 10% of patients.

Abstract
Background At the time of planned pancreatoduodenectomy patients frequently undergo exploratory laparotomy without resection, leading to delayed systemic therapy. This study aimed to develop and validate a prognostic model for the preoperative prediction of resectability of pancreatic head tumours. Methods This was a retrospective study of patients undergoing attempted resection for confirmed malignant tumours of the pancreatic head in a university hospital in Hannover, Germany. The prognostic value of patient and tumour characteristics was investigated in a multivariable logistic regression model. External validation was performed using data from two other centres. Results Some 109 patients were included in the development cohort, with 51 and 175 patients in the two validation cohorts. Eighty patients (73·4 per cent) in the development cohort underwent resection, and 37 (73 per cent) and 141 (80·6 per cent) in the validation cohorts. The main reasons for performing no resection in the development cohort were: local invasion of vasculature or arterial abutment (15 patients, 52 per cent), and liver (12, 41 per cent), peritoneal (8, 28 per cent) and aortocaval lymph node (6, 21 per cent) metastases. The final model contained the following variables: time to surgery (odds ratio (OR) 0·99, 95 per cent c.i. 0·98 to 0·99), carbohydrate antigen 19-9 concentration (OR 0·99, 0·99 to 0·99), jaundice (OR 4·45, 1·21 to 16·36) and back pain (OR 0·02, 0·00 to 0·22), with an area under the receiver operating characteristic (ROC) curve (AUROC) of 0·918 in the development cohort. AUROC values were 0·813 and 0·761 in the validation cohorts. The positive predictive value of the final model for prediction of resectability was 98·0 per cent in the development cohort, and 91·7 and 94·7 per cent in the two external validation cohorts. [Corrections added on 18 July 2018, after first online publication: The figures for OR of the variables time to surgery and CA19-9 in the abstract and in Table 3 and Table 4 were amended from 1·00 to 0·99]. Conclusion For preoperative prediction of the likelihood of resectability of pancreatic head tumours, this validated model is a valuable addition to CT findings.

Abstract
BACKGROUND This study aimed to evaluate the additional value of laparoscopic ultrasound (LUS) to staging laparoscopy (SL) for detecting occult liver metastases in patients with potentially resectable pancreatic head cancer. METHODS A retrospective cohort study was performed including all patients who underwent SL and LUS between 2005 and 2016. LUS was performed during SL to detect liver metastases not found by preoperative imaging or visual inspection of the liver. RESULTS Out of 197 patients, visual inspection during SL detected distant metastases in 29 (14.7%) patients. LUS was performed in 127 patients, revealing 3 additional liver metastases. The proportion of patients with unresectable disease after SL and negative LUS was 32.3%, which was similar to 36.6% of patients with unresectable disease after SL without LUS (difference 4.3%; 95% CI - 13-23%; P = 0.61). Sensitivity, specificity, and positive and negative predictive values of LUS to detect liver metastases were 30, 100, 100, and 94%, respectively. The proportion of patients with distant metastases diagnosed at SL significantly increased over time (P = 0.031). CONCLUSION The routine use of LUS during SL for patients with potentially resectable pancreatic head cancer cannot be recommended. Imaging should be repeated when significant delay occurs between index CT and the scheduled surgery.

Abstract
BACKGROUND Proper staging is critical to the management of pancreatic ductal carcinoma (PDAC). Laparoscopy has been used to stage patients without gross metastatic disease with variable success. OBJECTIVES We aimed to identify the frequency of patients diagnosed by laparoscopy with occult metastatic disease. Also, we looked for variables related to a higher chance of occult metastasis. METHODS Patients with PDAC submitted to staging laparoscopy either immediately before pancreatectomy or as a separate procedure between January 2010 and December 2016 were included. None presented gross metastatic disease at initial staging. We used logistic regression to search for variables associated with metastatic disease. RESULTS The study population consisted of 63 patients. Among all patients, nine (16.7%) had occult metastases at laparoscopy. Unresectable tumor (Odds ratio = 18.0, P = 0.03), increasing tumor size (Odds ratio = 1.36, P = 0.01), and abdominal pain (Odds ratio = 5.6, P = 0.04) significantly predicted the risk of occult metastases in univariate analysis. In multivariate analysis, only tumor size predicted the risk of occult metastases. CONCLUSION Laparoscopy remains a valuable tool in PDAC staging. Patients with either large or unresectable tumors, or presenting with abdominal pain present the highest risk for occult intra-abdominal metastases.

Abstract
BACKGROUND Robot surgery is a new method that maintains advantages and overcomes disadvantages of conventional methods, even in pancreatic surgery. This study aimed to evaluate safety and benefits of robot-assisted minimally invasive pancreaticoduodenectomy (robot PD). METHODS This study included 237 patients who underwent PD between 2015 and 2017. Demographics and surgical outcomes were evaluated. RESULTS Fifty-one patients underwent robot PD and 186 underwent open PD. Robot PD group had younger age (60.7 vs. 65.4 years, P = 0.006) and lower body mass index (22.7 vs. 24.0, P = 0.007). Robot PD group had lower proportion of patients with firm or hard pancreatic texture (15.7% vs. 38.2%, P = 0.004) and smaller pancreatic duct size (2.3 vs. 3.3 mm, P = 0.002). Two groups had similar operation time (robot vs. open: 335.6 vs. 330.1 min) and complications (15.7% vs. 21.0%), including postoperative pancreatic fistula rate (6.0% vs. 12.0%). Robot PD group had lower postoperative pain score (3.7 vs. 4.1 points, P = 0.008), and shorter postoperative stay (10.6 vs. 15.3 days, P = 0.001). CONCLUSION Robot PD is comparable to open PD in early outcomes. Robot PD is safe and feasible and enables early recovery; indication for robot PD is expected to expand in the near future.

Abstract
BACKGROUND Recent advances in imaging and the increasing use of neoadjuvant therapy puts the contemporary utility of staging laparoscopy for patients with pancreatic adenocarcinoma (PDAC) into question. This study aimed to develop a prognostic score to optimize prevention of an unnecessary laparotomy and minimize the rate for unnecessary laparoscopy. METHODS Clinicopathologic data were evaluated for all patients undergoing surgical intervention for PDAC between 2001 and 2015, who were stratified into group 1 (2001-2008) and group 2 (2009-2014). RESULTS The study identified 1001 patients eligible for analysis, 331 (33%) of whom underwent a staging laparoscopy before exploration. An unnecessary laparotomy was prevented for 44.4% of the patients in period 1 and for 24% of the patients in period 2 (p < 0.001). Male gender [odds ratio (OR), 1.8; p < 0.05], preoperative resectability (borderline resectable OR 2.1; p < 0.019; locally advanced OR 7.6; p < 0.001), CA 19-9 levels higher than 394 U/L (OR 3.1; p < 0.001), no neoadjuvant chemotherapy (OR 2.7; p = 0.012), and pancreatic body or tail lesions (OR 1.8; p = 0.063) were predictive of occult metastatic disease. The developed scoring index demonstrated a c-statistic of 0.729. The observed-to-expected ratio for the index at every score level validated the index's model. A score cutoff at 4 was able to detect 76.1% of radiographically occult metastatic disease. CONCLUSION The rate for unnecessary laparotomy among patients with PDAC has decreased in contemporary times, but unnecessary laparotomy still occurs for 1 in 4 patients. Using our scoring system, a cutoff of 4 allows 76% of radiographically occult metastases to be predicted, thereby selecting high-risk patients for laparoscopic biopsy and potentially avoiding a non-therapeutic laparotomy.

Abstract
In recent years, laparoscopic pancreatoduodenectomy (LPD) has been gaining a favorable position in the field of pancreatic surgery. However, its role still remains unclear. This review investigates the current status of LPD in high-volume centers. A literature search was conducted in PubMed, and only papers written in English containing more than 30 cases of LPD were selected. Papers with "hybrid" or robotic technique were not included in the analysis. Out of a total of 728 LPD publications, 7 publications matched the review criteria. The total number of patients analyzed was 516, and the largest series included 130 patients. Four of these studies come from the United States, 1 from France, 1 from South Korea, and 1 from India. In 6 reports, LPDs were performed only for malignant disease. The overall pancreatic fistula rate grades B-C were 12.7%. The overall conversion rate was 6.9%. LPD seems to be a valid alternative to the standard open approach with similar technical and oncological results. However, the lack of many large series, multi-institutional data, and randomized trials does not allow the clarification of the exact role of LPD.

Abstract
BACKGROUND: Recently, total laparoscopic pancreatectomy has been performed at many centres as an alternative to open surgery. In this study, we aimed to present the difficulties that we have encountered in converting from classic open pancreaticoduodenectomy to total laparoscopic pancreatectomy. MATERIALS AND METHODS: Between December 2012 and January 2014, we had 100 open pancreaticoduodenectomies. Subsequently, we tried to perform total laparoscopic pancreaticoduodenectomy (TLPD) in 22 patients. In 17 of these 22 patients, we carried out the total laparoscopic procedure. We analysed the difficulties that we encountered converting to TLPD in three parts: Preoperative, operative and postoperative. Preoperative difficulties involved patient selection, preparation of operative instruments, and planning the operation. Operative difficulties involved the position of the trocars, dissection, and reconstruction problems. The postoperative difficulty involved follow-up of the patient. RESULTS: According to our experiences, the most important problem is the proper selection of patients. Contrary to our previous thoughts, older patients who were in better condition were comparatively more appropriate candidates than younger patients. This is because the younger patients have generally soft pancreatic texture, which complicates the reconstruction. The main operative problems are trocar positions and maintaining the appropriate position of the camera, which requires continuous changes in its angles during the operation. However, postoperative follow-up is not very different from the classic procedure. CONCLUSION: TLPD is a suitable procedure under appropriate conditions.

Abstract
BACKGROUND Surgical resection is the only potentially curative treatment for pancreatic and periampullary cancer. A considerable proportion of patients undergo unnecessary laparotomy because of underestimation of the extent of the cancer on computed tomography (CT) scanning. Laparoscopy can detect metastases not visualised on CT scanning, enabling better assessment of the spread of cancer (staging of cancer). This is an update to a previous Cochrane Review published in 2013 evaluating the role of diagnostic laparoscopy in assessing the resectability with curative intent in people with pancreatic and periampullary cancer. OBJECTIVES To determine the diagnostic accuracy of diagnostic laparoscopy performed as an add-on test to CT scanning in the assessment of curative resectability in pancreatic and periampullary cancer. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via PubMed, EMBASE via OvidSP (from inception to 15 May 2016), and Science Citation Index Expanded (from 1980 to 15 May 2016). SELECTION CRITERIA We included diagnostic accuracy studies of diagnostic laparoscopy in people with potentially resectable pancreatic and periampullary cancer on CT scan, where confirmation of liver or peritoneal involvement was by histopathological examination of suspicious (liver or peritoneal) lesions obtained at diagnostic laparoscopy or laparotomy. We accepted any criteria of resectability used in the studies. We included studies irrespective of language, publication status, or study design (prospective or retrospective). We excluded case-control studies. DATA COLLECTION AND ANALYSIS Two review authors independently performed data extraction and quality assessment using the QUADAS-2 tool. The specificity of diagnostic laparoscopy in all studies was 1 because there were no false positives since laparoscopy and the reference standard are one and the same if histological examination after diagnostic laparoscopy is positive. The sensitivities were therefore meta-analysed using a univariate random-effects logistic regression model. The probability of unresectability in people who had a negative laparoscopy (post-test probability for people with a negative test result) was calculated using the median probability of unresectability (pre-test probability) from the included studies, and the negative likelihood ratio derived from the model (specificity of 1 assumed). The difference between the pre-test and post-test probabilities gave the overall added value of diagnostic laparoscopy compared to the standard practice of CT scan staging alone. MAIN RESULTS We included 16 studies with a total of 1146 participants in the meta-analysis. Only one study including 52 participants had a low risk of bias and low applicability concern in the patient selection domain. The median pre-test probability of unresectable disease after CT scanning across studies was 41.4% (that is 41 out of 100 participants who had resectable cancer after CT scan were found to have unresectable disease on laparotomy). The summary sensitivity of diagnostic laparoscopy was 64.4% (95% confidence interval (CI) 50.1% to 76.6%). Assuming a pre-test probability of 41.4%, the post-test probability of unresectable disease for participants with a negative test result was 0.20 (95% CI 0.15 to 0.27). This indicates that if a person is said to have resectable disease after diagnostic laparoscopy and CT scan, there is a 20% probability that their cancer will be unresectable compared to a 41% probability for those receiving CT alone.A subgroup analysis of people with pancreatic cancer gave a summary sensitivity of 67.9% (95% CI 41.1% to 86.5%). The post-test probability of unresectable disease after being considered resectable on both CT and diagnostic laparoscopy was 18% compared to 40.0% for those receiving CT alone. AUTHORS' CONCLUSIONS Diagnostic laparoscopy may decrease the rate of unnecessary laparotomy in people with pancreatic and periampullary cancer found to have resectable disease on CT scan. On average, using diagnostic laparoscopy with biopsy and histopathological confirmation of suspicious lesions prior to laparotomy would avoid 21 unnecessary laparotomies in 100 people in whom resection of cancer with curative intent is planned.

Abstract
BACKGROUND To identify indications for staging laparoscopy (SL) in patients with resectable pancreatic cancer, and suggest a pre-operative algorithm for staging these patients. METHODS Relevant articles were reviewed from the published literature using the Medline database. The search was performed using the keywords 'pancreatic cancer', 'resectability', 'staging', 'laparoscopy', and 'Whipple's procedure'. RESULTS Twenty four studies were identified which fulfilled the inclusion criteria. Of the published data, the most reliable surrogate markers for selecting patients for SL to predict unresectability in patients with CT defined resectable pancreatic cancer were CA 19.9 and tumour size. Although there are studies suggesting a role for tumour location, CEA levels, and clinical findings such as weight loss and jaundice, there is currently not enough evidence for these variables to predict resectability. Based on the current data, patients with a CT suggestive of resectable disease and (1) CA 19.9 ≥150 U/mL; or (2) tumour size >3 cm should be considered for SL. CONCLUSION The role of laparoscopy in the staging of pancreatic cancer patients remains controversial. Potential predictors of unresectability to select patients for SL include CA 19.9 levels and tumour size.

Abstract
BACKGROUND In patients affected by distal biliary obstruction deemed unsuitable for pancreatoduodenectomy, biliary diversion is the only proposable option. Defined goals of this treatment are: relief from jaundice preventing its related complications, reduction of in-hospital stay and adequate control of pain. Palliation can be obtained either by surgical or conservative procedures (endoscopic stenting or percutaneous treatment). Considering early complications' incidence, surgical approach has always been reserved for low surgical risk patients with longer survival perspectives, while recently developed long-lasting patency stents enlarged mini-invasive application resort. Comparative studies on these therapeutic options favour the conservative one in respect of conventional open surgery, but data on minimally invasive surgery to pursue palliative aims are lacking. We present our six-years casuistic and results referring to laparoscopic biliary diversions. METHODS We analyzed results obtained in distal biliary neoplastic obstruction management between December 2008 and November 2014. During this period, selected patients considered unsuitable for pancreatoduodenectomy were scheduled to receive a laparoscopic biliary decompression. Perioperative variables and 30-days postoperative outcomes have been prospectively collected. RESULTS In the six-years period, 12 patients affected by distal biliary neoplastic obstruction were submitted to laparoscopic palliative bypass. Four procedures were proposed for distal biliary cancer, one for advanced periampullary cancer and seven for pancreatic head cancer. Ten hepatico-jejunal bypasses and two choledochoduodenostomies have been performed. No conversions to open surgery were encountered in this series. Main operative time was 85 min, main blood loss was 75 ml and main hospitalization was 4.5 days. According to Clavien Dindo Classification one class II and one class IIIb complications occurred. CONCLUSIONS Although the restricted number of patients, our results suggest that laparoscopic biliary bypass could be a valid option in managing distal biliary obstructions, resulting in low perioperative morbidity, effective long term palliation of symptoms and improved quality of life.

Abstract
Distal pancreatic cancer is an aggressive malignancy with insidious and subtle presentation, low radical resection rate and poor prognosis. The effectiveness of treatments for this disease remains to be improved. Radical resection is the only curable treatment. Personalized therapeutic strategy with surgical resection as a core should be the standard mode for these patients, and a professional multidisciplinary team is indispensable. Patients with borderline resectable cancers may benefit from a neoadjuvant approach by initiating chemotherapy and/or chemoradiation prior to the resection. Radical antegrade modular pancreatosplenectomy (RAMPS) is designed to establish an operation with oncologic rationales and should be the standard radical resection mode for distal pancreatic cancer. The use of diagnostic laparoscopy can help find hepatic metastases and peritoneal dissemination to avoid an unnecessary open operation. Laparoscopic distal pancreatectomy has many advantages compared with open operation, but is only applicable to early-stage patients with small tumors. In addition, the long-term oncologic effects of this surgical procedure still need to be verified, and it should be carried out selectively. Radical distal (or left) pancreatectomy with resection of the celiac axis (DP-CAR) is proper for some patients with evidence of celiac arterial invasion and should be conducted meticulously. However, new breakthroughs in early diagnosis and genetically personalized therapy are urgently needed. We still need prospective, randomized studies in multicenter institutions to provide more evidence for the neoadjuvant approach and laparoscopic distal pancreatectomy.

Abstract
Pancreatic cancer is known for its typically late presentation and poor survival rates, with overall 5-year survival of less than 5%. The role of chemotherapy alone or with radiotherapy in the management of locally advanced tumors continues to be an area of debate.We report a case of locally advanced, pancreatic adenosquamous carcinoma that was initially deemed unresectable intraoperatively. Nonetheless, the tumor was resected after radiological response to gemcitabine-capecitabine chemoradiotherapy regimen similar to the Selective Chemoradiation in Advanced LOcalised Pancreatic cancer trial. Histological examination revealed complete pathological response with extensive fibrosis (ypT0 N0). On 12-month follow-up CT, a single liver lesion in the left lateral segment was identified and confirmed to be a metastasis with cytological diagnosis via EUS and FNA. The disease remained stable and confined to the solitary hepatic metastasis after further gemcitabine chemotherapy. Therefore, a further successful resection was performed.The 2 main strategies for the management of locally advanced unresectable pancreatic cancer are chemotherapy induction followed by consolidation chemoradiotherapy or chemotherapy alone, with conflicting published evidence. Evidence for the optimal management of the rare histological type of adenosquamous carcinoma is scant. We present a case of such tumor with a complete pathological response to chemoradiotherapy. The results of future studies in the area are eagerly awaited.

Abstract
Pancreatic resection is a complex procedure that involves exposure of the retroperitoneal gland, dissection around major vascular structures, and management of an intricate organ, all of which results in a procedure associated with a high morbidity. The application of minimally invasive techniques to pancreatic resection have been studied only relatively recently. This analysis of the current concepts in minimally invasive pancreatic surgery focuses on a select look at currently published series or reviews from centers and groups that have the most experience with this procedure. We aim to present a comprehensive review gained from the experiences of those who are on the leading edge of the learning curve, with an emphasis on describing the similarities and differences between the minimally invasive and open pancreatic procedure. Minimally invasive distal pancreatectomy appears to be on the verge of widespread acceptance and shows clear benefits over its open counterpart. Minimally invasive proximal (right-sided) pancreatectomy, on the other hand, appears to be limited to select centers that have been able to demonstrate promising results despite its challenges. Additionally, minimally invasive central pancreatectomy and enucleation appear feasible as experience is gained in laparoscopic and robotic pancreatic resection.

Abstract
A major challenge with pancreatic cancer management is in the discrimination of clearly resectable tumors from those that would likely be accompanied by a positive resection margin if upfront surgery was attempted. The standard of care for clearly resectable pancreatic cancer remains surgery followed by adjuvant therapy, but there is considerable controversy over whether such therapeutic adjuvant strategies should include radiotherapy. Furthermore, in a malignancy with such high rates of distant metastasis, investigators are now exploring the feasibility and outcomes of delivering therapy in the neoadjuvant setting, both for clearly resectable as well as borderline resectable tumors. In this review, we explore the current standard of care of upfront surgery for clearly resectable cancers followed by adjuvant therapy, focusing on the role of radiotherapy. We highlight the difficulties in interpreting a literature fraught with inconsistencies in how resectable vs borderline resectable cancers are defined and treated. Finally, we explore the role of neoadjuvant strategies in the modern era.

Abstract
AIM: To assess the value of D-dimer level in determining resectability of pancreatic cancer.
METHODS: Preoperative prediction of pancreatic head cancer resectability remains inaccurate. The use of hemostatic factors may be of potential help, since D-dimers correlate with tumor stage. Single center clinical trial study comprised patients with potentially resectable pancreatic head tumor and without detectable venous thrombosis (n = 64). Resectability was defined as no evidence of nodal involvement, distant spread and no invasion of mesenteric vessels. Final decision of resectability was confirmed intraoperatively. Experienced pancreatic surgeon performed all surgeries. Following the dissection of hepatoduodenal ligament, samples of portal blood and bile were taken. Peripheral blood via central line and urine via Foley catheter were sampled. D-dimer levels were further measured.
RESULTS: At laparotomy only 29 (45.3%) tumors were found to be resectable. Our analysis showed higher by 57.5% (P < 0.001) mean D-dimer values in peripheral and 43.7% (P = 0.035) in portal blood of patients with unresectable pancreatic cancer. Significant differences were not observed when analyzing D-dimer levels in bile and urine. Peripheral D-dimer level correlated with pancreatic cancer resectability. When cut-off D-dimer value of 570.6 μg/L was used, the sensitivity for assessment of tumor unresectability was 82.8%. Furthermore, D-dimer level in peripheral blood of metastatic disease (n = 15) was significantly higher when compared to locally advanced (n = 20) pancreatic cancer (2470 vs 1168, P = 0.029). The area under ROC curve for this subgroup of patients was 0.87; for determination of unresectable disease when threshold of 769.8 μg/L was used, sensitivity and specificity was 86.6% and 80%, respectively.
CONCLUSION: Patients with resectable pancreatic head cancer based on preoperative imaging studies and high D-dimer level may be considered unresectable due to occult hepatic metastases. These patients may benefit from diagnostic laparoscopy to avoid exploratory laparotomy.

Abstract
PURPOSE To evaluate, in a phase 2 study, the safety and efficacy of induction gemcitabine, oxaliplatin, and cetuximab followed by selective capecitabine-based chemoradiation in patients with borderline resectable or unresectable locally advanced pancreatic cancer (BRPC or LAPC, respectively). METHODS AND MATERIALS Patients received gemcitabine and oxaliplatin chemotherapy repeated every 14 days for 6 cycles, combined with weekly cetuximab. Patients were then restaged; "downstaged" patients with resectable disease underwent attempted resection. Remaining patients were treated with chemoradiation consisting of intensity modulated radiation therapy (54 Gy) and concurrent capecitabine; patients with borderline resectable disease or better at restaging underwent attempted resection. RESULTS A total of 39 patients were enrolled, of whom 37 were evaluable. Protocol treatment was generally well tolerated. Median follow-up for all patients was 11.9 months. Overall, 29.7% of patients underwent R0 surgical resection (69.2% of patients with BRPC; 8.3% of patients with LAPC). Overall 6-month progression-free survival (PFS) was 62%, and median PFS was 10.4 months. Median overall survival (OS) was 11.8 months. In patients with LAPC, median OS was 9.3 months; in patients with BRPC, median OS was 24.1 months. In the group of patients who underwent R0 resection (all of which were R0 resections), median survival had not yet been reached at the time of analysis. CONCLUSIONS This regimen was well tolerated in patients with BRPC or LAPC, and almost one-third of patients underwent R0 resection. Although OS for the entire cohort was comparable to that in historical controls, PFS and OS in patients with BRPC and/or who underwent R0 resection was markedly improved.

Abstract
Many patients with pancreas cancer present with locally advanced pancreatic cancer (LAPC). The principle tools used for diagnosis and staging of LAPC include endoscopic ultrasound, axial imaging with computed tomography and magnetic resonance imaging, and diagnostic laparoscopy. The definition of resectability has historically been vague, as there is considerable debate and controversy as to the definition of LAPC. For the patient with LAPC, there is some level of involvement of the surrounding vascular structures, which include the superior mesenteric artery, celiac axis, hepatic artery, superior mesenteric vein, or portal vein. When feasible, most surgeons would recommend possible surgical resection for patients with borderline LAPC, with the goal of an R0 resection. For initially unresectable LAPC, neoadjuvant should be strongly considered. Specifically, these patients should be offered neoadjuvant therapy, and the tumor should be assessed for possible response and eventual resection. The efficacy of neoadjuvant therapy with this approach as a bridge to potential curative resection is broad, ranging from 3%-79%. The different modalities of neoadjuvant therapy include single or multi-agent chemotherapy combined with radiation, chemotherapy alone, and chemotherapy followed by chemotherapy with radiation. This review focuses on patients with LAPC and addresses recent advances and controversies in the field.

Abstract
BACKGROUND The role of staging laparoscopy in pancreatic cancer in the age of high-resolution CT scans is under debate. This study's aim is to evaluate the efficacy of staging laparoscopy in this disease. STUDY DESIGN A retrospective cohort study was conducted evaluating patients who underwent operative treatment for radiographic stage I to III pancreatic cancer between July 2003 and October 2012. Radiographic follow-up was 94% at 6 months. RESULTS Of 274 patients who met inclusion criteria, 136 underwent staging laparoscopy, which identified radiographic occult distant metastases in 2% (3 of 136). However, subsequent laparotomy identified an additional 9% (12 of 136) harboring distant metastases in regions not visualized on standard staging laparoscopy; specifically, the posterior liver surface, paraduodenal retroperitoneum, proximal jejunal mesentery, and lesser sac. The remaining 138 patients underwent initial staging laparotomy, which showed similar results identifying radiographic occult distant disease in 11% (15 of 138). Within 6 months after the operation, peritoneal or subcapsular liver metastases developed in an additional 6% (15 of 257)-disease that potentially could have been diagnosed at the time of operation-providing a false-negative rate of 88% for staging laparoscopy compared with 36% for staging laparotomy. CONCLUSIONS Despite the availability of high-resolution CT scans, occult distant metastases can still be found in 11% of patients during the operation. In the absence of reliable risk factors to predict distant metastases, staging laparoscopy should be offered to all patients with radiographic localized disease. However, the results favor extended laparoscopic staging with evaluation of the posterior liver surface, mobilization of the duodenum, evaluation of the proximal jejunal mesentery, and visualization of the lesser sac.

Abstract
BACKGROUND Surgical resection is the only potentially curative treatment for pancreatic and periampullary cancer. A considerable proportion of patients undergo unnecessary laparotomy because of underestimation of the extent of the cancer on computed tomography (CT) scanning. Laparoscopy can detect metastases not visualised on CT scanning, enabling better assessment of the spread of cancer (staging of cancer). There has been no systematic review or meta-analysis assessing the role of diagnostic laparoscopy in assessing the resectability with curative intent in patients with pancreatic and periampullary cancer. OBJECTIVES To determine the diagnostic accuracy of diagnostic laparoscopy performed as an add-on test to CT scanning in the assessment of curative resectability in pancreatic and periampullary cancer. SEARCH METHODS We searched the Cochrane Register of Diagnostic Test Accuracy Studies, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via PubMed, EMBASE via OvidSP (from inception to 13 September 2012), and Science Citation Index Expanded (from 1980 to 13 September 2012). SELECTION CRITERIA We included diagnostic accuracy studies of diagnostic laparoscopy in patients with potentially resectable pancreatic and periampullary cancer on CT scan, where confirmation of liver or peritoneal involvement was by histopathological examination of suspicious (liver or peritoneal) lesions obtained at diagnostic laparoscopy or laparotomy. We accepted any criteria of resectability used in the studies. We included studies irrespective of language, publication status, or study design (prospective or retrospective). We excluded case-control studies. DATA COLLECTION AND ANALYSIS Two authors independently performed data extraction and quality assessment using the QUADAS-2 tool. The specificity of diagnostic laparoscopy in all studies was 1 because there were no false positives since laparoscopy and the reference standard are one and the same if histological examination after diagnostic laparoscopy is positive. Therefore, the sensitivities were meta-analysed using a univariate random-effects logistic regression model. The probability of unresectability in patients who had a negative laparoscopy (post-test probability for patients with a negative test result) was calculated using the median probability of unresectability (pre-test probability) from the included studies and the negative likelihood ratio derived from the model (specificity of 1 assumed). The difference between the pre-test and post-test probabilities gave the overall added value of diagnostic laparoscopy compared to the standard practice of CT scan staging alone. MAIN RESULTS Fifteen studies with a total of 1015 patients were included in the meta-analysis. Only one study including 52 patients had a low risk of bias and low applicability concern in the patient selection domain. The median pre-test probability of unresectable disease after CT scanning across studies was 40.3% (that is 40 out of 100 patients who had resectable cancer after CT scan were found to have unresectable disease on laparotomy). The summary sensitivity of diagnostic laparoscopy was 68.7% (95% CI 54.3% to 80.2%). Assuming a pre-test probability of 40.3%, the post-test probability of unresectable disease for patients with a negative test result was 0.17 (95% CI 0.12 to 0.24). This indicates that if a patient is said to have resectable disease after diagnostic laparoscopy and CT scan, there is a 17% probability that their cancer will be unresectable compared to a 40% probability for those receiving CT alone.A subgroup analysis of patients with pancreatic cancer gave a summary sensitivity of 67.9% (95% CI 41.1% to 86.5%). The post-test probability of unresectable disease after being considered resectable on both CT and diagnostic laparoscopy was 18% compared to 40% for those receiving CT alone. AUTHORS' CONCLUSIONS Diagnostic laparoscopy may decrease the rate of unnecessary laparotomy in patients with pancreatic and periampullary cancer found to have resectable disease on CT scan. On average, using diagnostic laparoscopy with biopsy and histopathological confirmation of suspicious lesions prior to laparotomy would avoid 23 unnecessary laparotomies in 100 patients in whom resection of cancer with curative intent is planned.

Phase II study of induction fixed-dose rate gemcitabine and bevacizumab followed by 30 Gy radiotherapy as preoperative treatment for potentially resectable pancreatic adenocarcinoma.

Abstract
BACKGROUND Eighty percent of patients with resected pancreatic ductal carcinoma (PDC) experience treatment failure within 2 years. We hypothesized that preoperative fixed-dose rate (FDR) gemcitabine (GEM) combined with the angiogenesis inhibitor bevacizumab (BEV) and accelerated 30 Gy radiotherapy (RT) would improve outcomes among patients with potentially resectable PDC. METHODS This phase II trial tested induction FDR GEM (1,500 mg/m(2)) plus BEV (10 mg/kg IV) every 2 weeks for three cycles followed by accelerated RT (30 Gy in 10 fractions) plus BEV directed at gross tumor volume plus a 1-2 cm vascular margin. Subjects underwent laparoscopy and resection after day 85. Therapy was considered effective if the complete pathologic response rate exceeded 10 % and the margin-negative resection rate exceeded 80%. RESULTS Fifty-nine subjects were enrolled; 29 had potential portal vein involvement. Two grade 4 (3.4%) and 19 grade 3 toxicities (32.8%) occurred. Four subjects manifested radiographic progression, and 10 had undetected carcinomatosis. Forty-three pancreatic resections (73%) were performed, including 19 portal vein resections (44%). Margin-negative outcomes were observed in 38 (88%, 95% confidence interval [CI] 75-96), with one complete pathologic response (2.3%; 95% CI 0.1-12). There were seven (6 grade 3; 1 grade 4) wound complications (13%). Median overall survival for the entire cohort was 16.8 months (95% CI 14.9-21.3) and 19.7 months (95% CI 16.5-28.2) after resection. CONCLUSIONS Induction therapy with FDR GEM and BEV, followed by accelerated BEV/RT to 30 Gy, was well tolerated. Although both effectiveness criteria were achieved, survival outcomes were equivalent to published regimens.

Abstract
Significant advances in imaging technology have changed the management of pancreatic cancer. In computed tomography (CT), this has included development of multidetector row, rapid, thin-section imaging that has also facilitated the advent of advanced reconstructions, which in turn has offered new perspectives from which to evaluate this disease. In magnetic resonance imaging, advances including higher field strengths, thin-section volumetric acquisitions, diffusion weighted imaging, and liver specific contrast agents have also resulted in new tools for diagnosis and staging. Endoscopic ultrasound has resulted in the ability to provide high-resolution imaging rivaling intraoperative ultrasound, along with the ability to biopsy via real time imaging suspected pancreatic lesions. Positron emission tomography with CT, while still evolving in its role, provides whole body staging as well as the unique imaging characteristic of metabolic activity to aid disease management. This article will review these modalities in the diagnosis and staging of pancreatic cancer.

Abstract
Abstract Malignancies of the hepato-pancreatico-biliary (HPB) system are relatively common and generally characterized by a dismal prognosis. Positron emission tomography (PET) is a functional imaging technique that has emerged as an important modality in oncological decision-making. The principal radiopharmaceutical in PET imaging is the glucose analog (18)F-fluorodeoxyglucose, which is able to detect altered glucose metabolism in malignant tissue. PET is typically used in conjunction with computed tomography (CT), and previous studies have supported several uses of PET/CT in HPB malignancies, including staging, differential diagnostics and monitoring of treatment response and progress of disease. A review of PET/CT in the context of HPB malignancies will be presented, including indications and potential pitfalls.

Abstract
Pancreatic cancer is the tenth most common cancer and the fourth leading cause of cancer deaths in the United States. Surgery remains a cornerstone in the treatment of pancreatic cancer. Unfortunately, the percentage of patients presenting at the resectable stage is minimal. Although computed tomography (CT) scan remains the best modality to stage the tumor for resectability, laparoscopy and laparoscopic ultrasound offers its own advantages. Extended lymphadenectomy, portal vein resection, and arterial reconstruction have also been explored in multiple studies to enhance staging. The traditional pancreaticoduodenectomy (Whipple's procedure) with regional lymphadenectomy is still the standard of care in the surgical treatment of pancreatic cancer.

Abstract
INTRODUCTION Between 4% and 13% of patients with operable pancreatic malignancy are found unresectable at the time of surgery. Double bypass is a good option for fit patients but it is associated with a high risk of postoperative complications. The aim of this study was to identify pre-operatively which patients undergoing double bypass are at high risk of complications and to assess their long-term outcome. METHODS Of the 576 patients undergoing pancreatic resections between 2006 and 2011, 50 patients who underwent a laparotomy for a planned pancreaticoduodenectomy had a double bypass procedure for inoperable disease. Demographic data, risk factors for postoperative complications and pre-operative anaesthetic assessment data including the Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (P-POSSUM) and cardiopulmonary exercise testing (CPET) were collected. RESULTS Fifty patients (33 men and 17 women) were included in the study. The median patient age was 64 years (range: 39-79 years). The complication rate was 50% and the in-hospital mortality rate was 4%. The P-POSSUM physiology subscore and low anaerobic threshold at CPET were significantly associated with postoperative complications (p =0.005 and p =0.016 respectively) but they were unable to predict them. Overall long-term survival was significantly shorter in patients with postoperative complications (9 vs 18 months). Postoperative complications were independently associated with poorer long-term survival (p =0.003, odds ratio: 3.261). CONCLUSIONS P-POSSUM and CPET are associated with postoperative complications but the possibility of using them for risk prediction requires further research. However, postoperative complications following double bypass have a significant impact on long-term survival and this type of surgery should therefore only be performed in specialised centres.

Abstract
BACKGROUND: Diagnostic laparoscopy helps in diagnosing and staging Gastrointestinal (GI) cancers. Routine laparoscopy before laparotomy, especially in cancers that have equivocal operability, helps to avoid unnecessary laparotomies. Present study evaluates utility of laparoscopy in diagnosing and staging GI cancers. MATERIALS AND METHODS: Diagnostic laparoscopy was done in 41 patients with gastrointestinal (GI) cancers who were thought to have equivocal operability. Patients with suspected or known non-metastatic GI cancers, in whom resectability was found doubtful by clinical assessment and pre-operative imaging, were included. Patients with non-GI cancers (lymphoma, gynaecologic cancers, genitourinary cancers, retroperitoneal sarcoma, sarcoma and abdominal metastasis of non-GI cancers) and metastatic cancers which were beyond the scope of curative surgery were excluded from the study. RESULTS: After diagnostic laparoscopy (DL) five patients had benign diagnosis. Out of 36 patients with malignant diagnosis, after DL, 22 patients (61.1%) were inoperable, 11 patients (30.6%) were operable, and three (8.3%) patients were of equivocal operability. Sensitivity, specificity, positive predictive value, and negative predictive value of laparoscopy in detecting operability were 100%, 91.7%, 81.8%, and 100%, respectively. CONCLUSIONS: Laparoscopy helped in a significant number of patients with advanced GI cancers to avoid laparotomy. The morbidity of DL was acceptable.

Abstract
In the era of multidetector high quality CT imaging, it is feasible and critical to use objective criteria to define resectable pancreatic cancer. This allows accurate pretreatment staging and the development of stage-specific therapy. Tumors of borderline resectability have emerged as a distinct subset and the definition has been expanded in the last few years. Borderline resectable tumors are defined as those with tumor abutment of <180degrees (< 50%) of the SMA or celiac axis, short segment abutment or encasement of the common hepatic artery typically at the gastroduodenal artery origin, SMV-PV abutment with impingement and narrowing or segmental venous occlusion with sufficient venous flow above and below the occlusion to allow an option for venous reconstruction. Most of the patients whose cancer meet these CT criteria are candidates for preoperative systemic chemotherapy followed by chemoradiation since they are at a high risk for margin positive resection with upfront surgery. Patients whose imaging studies show radiographic stability or regression proceed to pancreaticoduodenectomy (or pancreatectomy) and this may require vascular resection and reconstruction. Prospective biomarker and functional imaging enriched studies are warranted to determine the best overall treatment strategy for these patients.

Abstract
OBJECTIVES Routine application of positron emission tomography/computed tomography (PET/CT) for pancreatic cancer staging remains a controversial approach. The purpose of this study was to reassess the clinical impact of PET/CT for the detection of distant metastasis of pancreatic cancer. METHODS From January 2006 to June 2009, 125 patients with histologically proven pancreatic cancer that had undergone PET/CT at our hospital were retrospectively reviewed. To evaluate the clinical efficacy of PET/CT on the management plan, the post-PET/CT management plans were compared with the pre-PET/CT management plans. RESULTS After the conventional staging workup, we determined that 76 patients (60.8%) had resectable lesions, whereas 48 patients had unresectable lesions. One patient underwent explorative laparotomy due to equivocal resectability. Positron emission tomography/computed tomography diagnosed distant metastasis in only 2 (2.6%) of the 76 patients with resectable lesions, and these patients did not undergo unnecessary surgical treatment. Complete resection was not performed in 8 of the 74 operative patients because they had distant metastasis detected during the operative procedure. Positron emission tomography/computed tomography diagnosed distant metastasis in 32 of the 44 patients with metastatic lesions that were histologically shown to have sensitivity of 72.7%. CONCLUSIONS Positron emission tomography/computed tomography has a limited role in the evaluation of metastatic disease from pancreatic cancer.

Abstract
Complete surgical resection still remains the only possibility of curing pancreatic cancer, however, only 10% of patients undergo curative surgery. Pancreatic resection currently remains the only method of curing patients, and has a 5-year overall survival rate between 7%-34% compared to a median survival of 3-11 mo for unresected cancer. Pancreatic surgery is a technically demanding procedure requiring highly standardized surgical techniques. Nevertheless, even in experienced hands, perioperative morbidity rates (delayed gastric emptying, pancreatic fistula etc.) are as high as 50%. Different strategies to reduce postoperative morbidity, such as different techniques of gastroenteric reconstruction (pancreatico-jejunostomy vs pancreatico-gastrostomy), intraoperative placement of a pancreatic main duct stent or temporary sealing of the main pancreatic duct with fibrin glue have not led to a significant improvement in clinical outcome. The perioperative application of somatostatin or its analogues may decrease the incidence of pancreatic fistulas in cases with soft pancreatic tissue and a small main pancreatic duct (< 3 mm). The positive effects of external pancreatic main duct drainage and antecolic gastrointestinal reconstruction have been observed to decrease the rate of pancreatic fistulas and delayed gastric emptying, respectively. Currently, the concept of extended radical lymphadenectomy has been found to be associated with higher perioperative morbidity, but without any positive impact on overall survival. However, there is growing evidence that portal vein resections can be performed with acceptable low perioperative morbidity and mortality but does not achieve a cure.

Abstract
BACKGROUND Application of minimally invasive techniques in the surgical management of distal pancreatic lesions is increasing. Despite this, numbers of laparoscopic distal pancreatectomy remain low and limited to treatment of benign and premalignant lesions. METHODS Retrospective analysis of 31 patients who underwent distal pancreatectomy from 2005 to 2010. Patients were grouped according to mode of surgical access: open (ODP) or laparoscopic (LDP). Perioperative parameters were compared. RESULTS Twenty-one (67.7%) patients underwent ODP and 10 (32.3%) LDP (median age 61; 80.0% females in LDP group, p = 0.030). Postoperative morbidity rate were comparable between the two groups. In the LDP group, there were significantly lower estimated blood loss (p < 0.001) and amount of blood transfusion (p = 0.001), smaller tumor size (p = 0.010) and fewer lymph nodes harvested (p = 0.020), shorter postoperative length of stay (p = 0.020), and shorter length of stay in surgical high dependency (p = 0.001). CONCLUSION LDP is a safe, efficient technique for resection of benign and premalignant pancreatic lesions. Indices reflecting perioperative outcomes in this study are highly competitive with those in other major centers.

Abstract
BACKGROUND The aim of this study was to improve fluorescence laparoscopy of pancreatic cancer in an orthotopic mouse model with the use of a light-emitting diode (LED) light source and optimal fluorophore combinations. STUDY DESIGN Human pancreatic cancer models were established with fluorescent FG-RFP, MiaPaca2-GFP, BxPC-3-RFP, and BxPC-3 cancer cells implanted in 6-week-old female athymic mice. Two weeks postimplantation, diagnostic laparoscopy was performed with a Stryker L9000 LED light source or a Stryker X8000 xenon light source 24 hours after tail-vein injection of CEA antibodies conjugated with Alexa 488 or Alexa 555. Cancer lesions were detected and localized under each light mode. Intravital images were also obtained with the OV-100 Olympus and Maestro CRI Small Animal Imaging Systems, serving as a positive control. Tumors were collected for histologic analysis. RESULTS Fluorescence laparoscopy with a 495-nm emission filter and an LED light source enabled real-time visualization of the fluorescence-labeled tumor deposits in the peritoneal cavity. The simultaneous use of different fluorophores (Alexa 488 and Alexa 555), conjugated to antibodies, brightened the fluorescence signal, enhancing detection of submillimeter lesions without compromising background illumination. Adjustments to the LED light source permitted simultaneous detection of tumor lesions of different fluorescent colors and surrounding structures with minimal autofluorescence. CONCLUSIONS Using an LED light source with adjustments to the red, blue, and green wavelengths, it is possible to simultaneously identify tumor metastases expressing fluorescent proteins of different wavelengths, which greatly enhanced the signal without compromising background illumination. Development of this fluorescence laparoscopy technology for clinical use can improve staging and resection of pancreatic cancer.

Abstract
Because of the evolution of treatment strategies staging criteria for pancreatic cancer now emphasize arterial involvement for determining unresectable disease. Preoperative therapy may improve the likelihood of margin negative resections of borderline resectable tumors. Cross-sectional imaging is crucial for correctly staging patients. Magnetic resonance (MR) imaging and computed tomography (CT) are probably comparable, with MR imaging probably offering an advantage for identifying liver metastases. Positron emission tomography/CT and endoscopic ultrasound may be helpful for problem solving. Clear and concise reporting of imaging findings is important. Several national organizations are developing templates to standardize the reporting of imaging findings.
