Impact of Portal Vein Resection (PVR) in Patients Who Underwent Curative Intended Pancreatic Head Resection. Biomedicines 2023; 11:3025. [PMID: 38002027 PMCID: PMC10669675 DOI: 10.3390/biomedicines11113025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 09/25/2023] [Accepted: 11/09/2023] [Indexed: 11/26/2023] Open
Abstract
The oncological impact of portal vein resection (PVR) in pancreatic cancer surgery remains contradictory. Different variables might have an impact on the outcome. The aim of the present study is the retrospective assessment of the frequency of PVR, histological confirmation of tumor infiltration, and comparison of oncological outcomes in PVR patients. We retrieved n = 90 patients from a prospectively collected data bank who underwent pancreas surgery between 2012 and 2019 at the University Medical Centre Göttingen (Germany) and showed a histologically confirmed pancreatic ductal adenocarcinoma (PDAC). While 50 patients (55.6%) underwent pancreatic resection combined with PVR, 40 patients (44.4%) received standard pancreatic surgery. Patients with distal pancreatectomy or a tumor other than PDAC were excluded. PVR was performed either as local excision or circular resection of the portal vein. Clinical/patient data and follow-ups were retrieved. The median follow-up period was 20.5 months. Regarding the oncological outcome, a statistically poorer CSS (p = 0.04) was observed in PVR patients. There was no difference (p = 0.18) in patients' outcomes between tangential and complete PVR, while n = 21 (42% of PVR patients) showed portal vein infiltration. The correlation between performed PVR and resection status was statistically significant: 48.6% of PVR patients achieved R0 resections compared to 75% in non-PVR patients (p = 0.03). Patients who underwent PDAC surgery with PVR show a significantly poorer outcome regardless of PVR type. Tumor size and R-status remain two important variables significantly associated with outcome. Since there is a lack of standardization for the indication of PVR, it remains unknown if the need for resection of vein structures during pancreatic resection represents the biological aggressiveness of the tumor or is biased by the experience of the surgeon.

Abstract
BACKGROUND Surgery for patients with pancreatic cancer carries a high risk of major post-operative complications and only marginally improves overall survival. This review aims to assess the impact of surgical resection on health-related quality of life (HRQOL) of pancreatic cancer patients. METHODS A systematic review of the literature was performed according to the PRISMA guidelines. All studies assessing QOL using validated questionnaires in pancreatic cancer patients undergoing surgical resection were included. RESULTS Twenty-two studies were assessed. Patients reported a decrease in physical, social and global scales within the first 3 months after surgery. These values showed improvement and were comparable to baseline values by 6 months. Recovery in emotional functioning towards baseline figures was demonstrated in the first 3 months post-operatively. Symptom scales including pain, fatigue and diarrhoea deteriorated after surgery, but reverted to baseline after 3-6 months. CONCLUSIONS Surgical resection for pancreatic cancer has short-term negative impact on QOL. In the longer term, this will improve and eventually recover to baseline values after 6 months. Knowledge on the impact of surgery on QOL of pancreatic cancer patients is necessary to facilitate decision-making and tailoring of surgical techniques to the individual patient.

Abstract
PURPOSE Pancreatic cancer is one of the common types of malignant cancer. Low-dose-rate (LDR) brachytherapy has shown great efficacy in curing pancreatic cancer. However, a long preoperative planning time and an insufficient tumor dose are common issues. In this paper, we present and validate a method for inverse planning using simulated annealing (SA) for the treatment of pancreatic cancer. METHODS The SA method was used for the inverse planning process. With the help of parallel computation and a quick dose field estimation algorithm. This method allowed inverse planning to be performed quickly. A novel length-control method was used to consider and limit the dose of the organ at risk. The effect of this system was validated by calculating the dose-volume histogram metric and time consumption. RESULTS Regarding the percentage of the volume receiving 100% of the prescribed dose (V100), this approach yielded an average difference in V100 of 5.01% for the tumor and of 1.32% for the organ at risk in the small tumor group; in the large tumor group, the average difference in V100 was 2.3% for the tumor and - 4.49% for the organ at risk. The average time required for inverse planning was 1.63 ± 0.26 s for small tumors and 3.81 ± 0.51 s for large tumors. Compared with other inverse planning methods, the optimal quality of the plans yielded by this method was further improved. CONCLUSION This paper presents a new type of inverse planning method for the treatment of pancreatic cancer based on SA. Compared with other LDR inverse planning methods, the method presented here can provide the prescribed dose to the tumor while considering the dose of the organ at risk. Also, the required time is significantly lower than other methods. All the experimental results indicate that this method is ready to be applied in further clinical studies.

Abstract
Two areas that remain the focus of improvement in pancreatic cancer include high post-operative morbidity and inability to uniformly translate surgical success into long-term survival. This narrative review addresses specific aspects of pancreatic cancer surgery, including neoadjuvant therapy, vascular resections, extended pancreatectomy, extent of lymphadenectomy and current status of minimally invasive surgery. R0 resection confers longer disease-free survival and overall survival. Vascular and adjacent organ resections should be undertaken after neoadjuvant therapy, only if R0 resection can be ensured based on high-quality preoperative imaging, and that too, with acceptable post-operative morbidity. Extended lymphadenectomy does not offer any advantage over standard lymphadenectomy. Although minimally invasive distal pancreatectomies offers some short-term benefits over open distal pancreatectomy, safety remains a concern with minimally invasive pancreatoduodenectomy. Strict adherence to principles and judicious utilization of surgery within a multimodality framework is the way forward.

Abstract
ABSTRACT This systematic review aimed to investigate the instruments available to measure quality of life (QOL) after pancreatic cancer surgery and to describe short- and long-term QOL outcomes. A comprehensive literature search was completed using PubMed, Embase, and Medline from inception to March 2019. Studies investigating QOL outcomes in patients undergoing pancreatic cancer surgery who were 18 years or older were included. The main outcomes of interest were QOL instruments and short (≤6 months) and long term (>6 months) QOL outcomes. The overarching domains of physical, psychosocial, overall QOL, symptoms, and other were used to summarize QOL outcomes. Thirty-five studies reporting on 3573 patients were included. Fifteen unique QOL instruments were identified, of which 4 were disease-specific instruments. Most of the included studies reported no changes in QOL at short- and long-term follow-ups for the overarching domains. No difference in QOL outcomes was reported between different surgical approaches, except laparoscopic versus open distal pancreatectomy, and pancreaticoduodenectomy versus distal pancreatectomy. There are a wide range of instruments available to measure QOL outcomes in pancreatic cancer surgical patients, although only few are disease-specific. Most of the included studies reported no significant changes in QOL outcomes at short- or long-term follow-ups.

Abstract
BACKGROUND Locally-advanced pancreatic cancer (LAPC) is traditionally considered stage III unresectable disease. Advances in induction systemic therapy regimens, surgical technique, and perioperative care have led to successful resection of an increasing number of these tumors with reasonable perioperative outcomes and disease-free intervals. Certain anatomic characteristics that meet criteria for locally-advanced disease, however, are more likely to result in a successful surgical outcome. METHODS A practical and consistent system is needed to communicate such nuance between surgical and nonsurgical oncologists for optimal treatment planning and to improve recording for cancer registries and research studies. RESULTS The present study proposes a novel subclassification system for stage III pancreatic cancers based on their pattern of vascular involvement and examines the current evidence for resection in each scenario. Introducing needed detail into the current catch-all stage III categorization will help to direct patient referrals and increase the body of knowledge about the variable presentations of this complex malignancy. CONCLUSION This proposed staging revision for LAPC is designed to convey more actionable tumor descriptions for treating oncologists, clinical trial eligibility, and surgical patient selection in the era of effective induction systemic therapy.

Abstract
Simple Summary The literature is conflicting regarding the feasibility and survival outcomes of distal pancreatectomy with celiac axis resection (DP-CAR), although this procedure, in selected cases, represents the only therapeutical option for patients with locally advanced pancreatic cancer. The available studies often include small surgical populations, and there are important variations in the inclusion criteria and pre- and post-operative treatment. The purpose of this study was to provide an overview of the literature of the last 15 years, to evaluate the efficacy and the clinical safety of this procedure. This could help physicians in the choice of a multidisciplinary targeted therapeutical plan for patients. The combination of neoadjuvant chemo/radiochemotherapy and demolitive surgeries such as DP-CAR could have a role in changing the survival outcomes of patients with locally advanced pancreatic adenocarcinoma. Abstract Background: Major vascular invasion represents one of the most frequent reasons to consider pancreatic adenocarcinomas unresectable, although in the last decades, demolitive surgeries such as distal pancreatectomy with celiac axis resection (DP-CAR) have become a therapeutical option. Methods: A meta-analysis of studies comparing DP-CAR and standard DP in patients with pancreatic adenocarcinoma was conducted. Moreover, a systematic review of studies analyzing oncological, postoperative and survival outcomes of DP-CAR was conducted. Results: Twenty-four articles were selected for the systematic review, whereas eleven were selected for the meta-analysis, for a total of 1077 patients. Survival outcomes between the two groups were similar in terms of 1 year overall survival (OS) (odds ratio (OR) 0.67, 95% confidence interval (CI) 0.34 to 1.31, p = 0.24). Patients who received DP-CAR were more likely to have T4 tumors (OR 28.45, 95% CI 10.46 to 77.37, p < 0.00001) and positive margins (R+) (OR 2.28, 95% CI 1.24 to 4.17, p = 0.008). Overall complications (OR, 1.72, 95% CI, 1.15 to 2.58, p = 0.008) were more frequent in the DP-CAR group, whereas rates of pancreatic fistula (OR 1.16, 95% CI 0.81 to 1.65, p = 0.41) were similar. Conclusions: DP-CAR was not associated with higher mortality compared to standard DP; however, overall morbidity was higher. Celiac axis involvement should no longer be considered a strict contraindication to surgery in patients with locally advanced pancreatic adenocarcinoma. Considering the different baseline tumor characteristics, DP-CAR may need to be compared with palliative therapies instead of standard DP.

Radical Resection for Locally Advanced Pancreatic Cancers in the Era of New Neoadjuvant Therapy-Arterial Resection, Arterial Divestment and Total Pancreatectomy. Cancers (Basel) 2021; 13:cancers13081818.

Abstract
Simple Summary Aggressive arterial resection or total pancreatectomy in surgical treatment for locally advanced pancreatic cancer (LAPC) has gradually been encouraged thanks to new chemotherapy regimens such as FOLFIRINOX or Gemcitabine and nab-paclitaxel, which have provided more adequate patient selection and local tumor suppression, justifying aggressive local resection. The development of surgical techniques provides the safety of arterial resection (AR) for even major visceral arteries, such as the celiac axis or superior mesenteric artery. Total pancreatectomy has been re-evaluated as an effective option to balance both the local control and postoperative safety. In this review, we investigate the recent reports focusing on arterial resection and total pancreatectomy for locally advanced pancreatic cancer (LAPC) and discuss the rationale of such an aggressive approach in the treatment of PC. Abstract Aggressive arterial resection (AR) or total pancreatectomy (TP) in surgical treatment for locally advanced pancreatic cancer (LAPC) had long been discouraged because of their high mortality rate and unsatisfactory long-term outcomes. Recently, new chemotherapy regimens such as FOLFIRINOX or Gemcitabine and nab-paclitaxel have provided more adequate patient selection and local tumor suppression, justifying aggressive local resection. In this review, we investigate the recent reports focusing on arterial resection and total pancreatectomy for LAPC and discuss the rationale of such an aggressive approach in the treatment of PC. AR for LAPCs is divided into three, according to the target vessel. The hepatic artery resection is the simplest one, and the reconstruction methods comprise end-to-end, graft or transposition, and no reconstruction. Celiac axis resection is mainly done with distal pancreatectomy, which allows collateral arterial supply to the liver via the pancreas head. Resection of the superior mesenteric artery is increasingly reported, though its rationale is still controversial. Total pancreatectomy has been re-evaluated as an effective option to balance both the local control and postoperative safety. In conclusion, more and more aggressive pancreatectomy has become justified by the principle of total neoadjuvant therapy. Further technical standardization and optimal neoadjuvant strategy are mandatory for the global dissemination of aggressive pancreatectomies.

Abstract
BACKGROUND Pancreaticoduodenectomy is associated with high rates of morbidity. This combined with the psychological burden of cancer, may impact on a patient's quality of life (QoL), which can be measured by using patient-reported outcomes (PRO). OBJECTIVE To perform a systematic review to evaluate the measurement of PRO after pancreaticoduodenectomy for cancer. METHODS 7 different databases were searched using 2 groups of search terms, one relating to pancreaticoduodenectomy, and one to PRO. Three authors screened the search results independently in a systematic manner based on predefined inclusion and exclusion criteria. RESULTS 27 studies, with 2173 eligible patients were included in the final analysis. Most of the included studies used validated instruments. The European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire was most popular and used in 12 studies. The methodology of all included studies was also scrutinised. 12 studies were deemed to have high quality methodology according to pre-defined criteria. CONCLUSION The instruments and methods used to measure PRO are variable. The quality of PRO within the available literature has improved over time, as has the number of studies measuring PRO. PRO should be measured with uniformity in future trials so that patients can be provided with more comprehensive information regarding post-operative recovery and QoL during the shared decision-making process preoperatively.

Abstract
BACKGROUND The number of pancreatic resections due to cancers is increasing. While concomitant venous resections are routinely performed in specialized centers, arterial resections are still controversial. Nevertheless they are performed in patients presenting with locally advanced tumors. Our aim was to summarize currently available literature comparing peri-operative and long-term outcomes of arterial and non-arterial pancreatic resections. METHODS We included studies comparing pancreatic operations with and without concomitant arterial resection. Inclusion criteria were morbidity or mortality. Studies additionally reporting venous resections with no possibility of excluding this data during the extraction were discarded. RESULTS The initial search yielded 1651 records. Finally, 19 studies were included in the analysis involving 2710 patients. Arterial resection was associated with a greater risk of death(RR: 4.09; p < 0.001) and complications (RR: 1.4; p = 0.01). There were no differences in the rate of pancreatic fistula, biliary fistula rate, cardiopulmonary complications, length of hospital stay and non-R0 rate. Oncologically, patients after arterial resection were at higher risk of worse 3-year survival. CONCLUSION Arterial resection in pancreatic cancer is associated with an increased risk of mortality and complications in comparison to standard non-arterial resections. Nevertheless, arterial resection may become a viable treatment for selected patients in high volume centers.

Abstract
OBJECTIVE This study assesses the safety and outcomes of the largest cohort of pancreatectomy with arterial resection (P-AR). BACKGROUND A high postoperative mortality rate and uncertain oncologic benefits have limited the use of P-AR for locally advanced pancreatic adenocarcinoma. METHODS We retrospectively reviewed a prospectively maintained database of patients who underwent P-AR between January 1990 and November 2017. Univariate and multivariate Cox analyses were used to assess prognostic factors for survival. RESULTS There were 118 consecutive resections (51 pancreaticoduodenectomies, 18 total pancreatectomies, and 49 distal splenopancreatectomies). Resected arterial segments included the coeliac trunk (50), hepatic artery (29), superior mesenteric artery (35), and other segments (4). The overall mortality and morbidity were 5.1% and 41.5%, respectively. There were 84 (75.4%) patients who received neoadjuvant chemotherapy, 105 (89%) simultaneous venous resections, and 101 (85.5%) arterial reconstructions. The rates of R0 resection and pathologic invasion of venous and arterial walls were 52.4%, 74.2%, and 58%, respectively. The overall survival was 59%, 13%, and 11.8% at 1, 3, and 5 years, respectively. The median overall survival after resection was 13.70 months (CI 95%:11-18.5 mo). In multivariate analysis, R0 resection (HR: 0.60; 95% CI: 0.38-0.96; P = 0.01) and venous invasion (HR: 1.67; 95% CI: 1.01-2.63; P = 0.04) were independent prognostic factors. CONCLUSION In a specialized setting, P-AR for locally advanced pancreatic adenocarcinoma can be performed safely with limited mortality and morbidity. Negative resection margin and the absence of associated venous invasion might predict favorable long-term outcomes.

Abstract
The development of increasingly effective chemotherapy regimens and increasing tumor necrosis is allowing radical pancreatectomy to be re-evaluated. This systematic review examines the outcome of patients with locally advanced cancer of the pancreatic head after pancreatectomy with arterial resection. Electronic searches were performed on PubMed and Medline databases between January 2000 and December 2018. The end points were to determine the safety and overall survival after arterial resection in pancreatectomy. Thirteen studies with 467 patients were included. Celiac, hepatic, mesenteric, and splenic arteries were resected across all studies. The median overall morbidity was 52% (range, 37%-100%) and with major complications occurring in a median of 25% (range, 12%-54%) of patients. The median 90-day mortality was 5% (range, 0%-17%). R0 was achieved in 66% (range, 43%-100%) and R1 in 31% (range, 0%-74%). The median survival was 17 (range, 7-29) months with a 1- and 3-year survival of 59% (range, 16%-92%) and 17% (range, 0%-13%), respectively. Pancreatectomy with arterial resection may be safely performed in high-volume centers with acceptable survival results in highly selected patients. Pooling of data through a multi-institutional registry will allow a more accurate assessment of the safety and efficacy of this treatment strategy.

Abstract
Background This study aims to observe and analyze the clinical efficacy of the pancreaticoduodenectomy (PD) with total mesopancreas excision (TMpE) via the artery approach for carcinoma of head of the pancreas. Methods From October 2015 to October 2016, 60 patients with pancreatic head cancer were enrolled in this study. Twenty-eight patients were treated with PD with TMpE via the artery approach (group A), while 32 patients were treated with PD alone (group B) in our hospital. The clinical data of the patients were retrospectively collected, including intra-operative evaluation index, R0 resection rate of postoperative pathological specimens, postoperative complications, and the tumor recurrence time was observed after operation (at third, sixth, and 12th months). Clinical efficacy of PD with TMpE via the artery approach was evaluated between the two groups. Results There was no significant difference in the operation time or perioperative death between the two groups (P > 0.05). Postoperative specimen pathology showed that there was a statistically significant difference in the R0 resection rate between the two groups (P < 0.05). There was no significant difference in the incidence of postoperative complications between the two groups (P > 0.05). Tumor recurrence rate at month 3 post operation was 0 (0/28) in group A and 3.13% (1/32) in group B. There was no significant difference in the 6-month recurrence rate (P > 0.05). Postoperative recurrence rate in group A was significantly lower than that in group B at month 12 (P < 0.05). Conclusions The PD with TMpE via the artery approach treatment of pancreatic head cancer can reduce the amount of intra-operative bleeding and save the operation time without increasing postoperative complications. It provides effective technical support for combined vascular anastomosis in the treatment of pancreatic head cancer with venous system invasion, and ensures the safety of operation. Moreover, this procedure can improve the R0 resection rate and reduce the recurrence rate in the near future. As a safe, effective and feasible surgical method for the treatment of pancreatic head cancer, it can be widely used in clinical practice.

Abstract
BACKGROUND Patients undergoing pancreatoduodenectomy for pancreatic cancer have a high risk of major postoperative complications and a low survival rate. Insight in the impact of pancreatoduodenectomy on quality of life (QoL) is therefore of great importance. The aim of this systematic review was to assess QoL after pancreatoduodenectomy for pancreatic cancer. METHODS A systematic review of the literature was performed according to the PRISMA guidelines. A systematic search of all the English literature available in PubMed and Medline was performed. All studies assessing QoL with validated questionnaires in pancreatic cancer patients undergoing pancreatoduodenectomy were included. RESULTS After screening a total of 788 articles, the full texts of 36 articles were assessed, and 17 articles were included. QoL of physical and social functioning domains decreased in the first 3 months after surgery. Recovery of physical and social functioning towards baseline values took place after 3-6 months. Pain, fatigue and diarrhoea scores deteriorated postoperatively, but eventually resolved after 3-6 months. CONCLUSION Pancreatoduodenectomy for malignant disease negatively influences QoL in the physical and social domains at short term. It will eventually recover to baseline values after 3-6 months. This information is valuable for counselling and expectation management of patients undergoing pancreatoduodenectomy.

Abstract
BACKGROUND Surgery for pancreatic cancer yields significant morbidity and mortality risks and survival is limited. Therefore, the influence of complications on quality of life (QoL) after pancreatic surgery is important. This study compares QoL in patients with and without severe complications after surgery for pancreatic (pre-)malignancy. METHODS This prospective cohort study scored complications after pancreatic surgery according to the Clavien-Dindo system and the definitions of the International Study Group of Pancreatic Surgery. QoL was measured by the RAND36 questionnaire, the European Organization for Research and Treatment of Cancer core questionnaire (QLQ-C30) and the pancreas specific QLQ-PAN26. QoL in patients with severe complications was compared with QoL in patients with no or mild complications over a period of 12 months. Analysis was performed with linear mixed models for repeated measurements. RESULTS Between March 2012 and July 2016, 137 patients were included. Sixty-eight patients (50%) had at least 1 severe complication. There were no statistically significant and clinically relevant differences between both groups in QoL up to 12 months after surgery. CONCLUSION In this study, no differences in QoL between patients with and without severe postoperative complications were encountered during the first 12 months after surgery for pancreatic (pre-)malignancy.

Abstract
OBJECTIVES The economic evaluation (EE) of healthcare interventions has become a necessity. However, high quality needs to be ensured in order to achieve validated results and help making informed decisions. Thus, the objective of the present study was to systematically identify and review published pancreatic ductal adenocarcinoma-related EEs and to assess their quality. METHODS Systematic literature research was conducted in PubMed and Cochrane to identify published EEs between 2000 and 2015. The quality of each selected EE was assessed by two independent reviewers, using the Drummond's checklist. RESULTS Our systematic review was based on 32 EEs and showed a wide variety of methodological approaches, including different perspectives, time horizon, and cost effectiveness analyses. Nearly two-thirds of EEs are full EEs (n = 21), and about one-third of EEs had a Drummond score ≥7, synonymous with 'high quality'. Close to 50% of full EEs had a Drummond score ≥7, whereas all of partial EEs had a Drummond score <7 (n = 11). CONCLUSIONS Over the past 15 years, a lot of interest has been evinced over the EE of pancreatic ductal adenocarcinoma (PDAC) and its direct impact on therapeutic advances in PDAC. To provide a framework for health care decision-making, to facilitate transferability and to lend credibility to health EEs, their quality must be improved. For the last 4 years, a tendency towards a quality improvement of these studies has been observed, probably coupled with a context of rational decision-making in health care, a better and wider spread of recommendations and thus, medical practitioners' full endorsement.

Abstract
PURPOSE Arterial involvement in advanced pancreatic cancer generally defines local unresectability. This study was aimed to evaluate the clinical outcomes of combined common hepatic arterial resection with pancreaticoduodenectomy or total pancreatectomy in patients with locally advanced pancreatic cancer involving the hepatic artery. METHODS Of 348 patients with pancreatic head cancers who underwent surgical resection between June 1999 and September 2015, 21 underwent combined common hepatic arterial resection with pancreaticoduodenectomy (17) or total pancreatectomy (4). Preoperative common hepatic arterial embolization was performed in 12 patients. Preoperative CT findings of hepatic arterial involvement, postoperative complications, survival rates, and prognostic factors for survival were analyzed. Twenty-one unresectable patients with locally advanced pancreatic cancer who underwent laparotomy in this study period were selected as the control group. RESULTS Rates of pathological arterial invasion were significantly higher in patients with level III (>1800) CT findings (90%,9/10) than in patients with levels I and II (<1800) (27%, 3/11) (p < 0.01). No surgical deaths occurred. Survival after surgical resection in all 21 patients was 47.6%, 6.6%, and 6.6% at 1, 3, and 5 years, and median survival was 11 months. The preoperative serum CA19-9 level was a significant prognostic factor for overall survival, median survivals were 21.5 and 8.3 months in the low CA19-9 and high CA19-9 groups, respectively. No significant difference in survival between the high-CA19-9 group and the unresectable group was found. CONCLUSIONS Combined common hepatic arterial resection in pancreaticoduodenectomy or total pancreatectomy might be feasible with an acceptable rate of surgical complications, and may have a beneficial effect on the prognosis only in patients with low preoperative serum CA19-9 levels.

Abstract
INTRODUCTION The benefit of portal-superior mesenteric vein resection (PSMVR) with pancreatoduodenectomy (PD) remains controversial. This study assesses the impact of PSMVR on resection margin status and survival. METHOD An electronic search was performed to identify relevant articles. Pooled odds ratios were calculated for outcomes using the fixed or random-effects models for meta-analysis. A decision analytical model was developed for estimating cost effectiveness. RESULTS Sixteen studies with 4145 patients who underwent pancreatoduodenectomy were included: 1207 patients had PSMVR and 2938 patients had no PSMVR. The R1 resection rate and post-operative mortality was significantly higher in PSMVR group (OR1.59[1.35, 1.86] p=<0.0001, and OR1.72 [1.02,2.92] p = 0.04 respectively). The overall survival at 5-years was worse in the PSMVR group (HR0.20 [0.07,0.55] P = 0.020). Tumour size (p = 0.030) and perineural invasion (P = 0.009) were higher in the PSMVR group. Not performing PSMVR yielded cost savings of $1617 per additional month alive without reduction in overall outcome. CONCLUSION On the basis of retrospective data this study shows that PD with PSMVR is associated with a higher R1 rate, lower 5-year survival and is not cost-effective. It appears that PD with PSMVR can only be justified if R0 resection can be achieved. The continuing challenge is accurate selection of these patients.

Abstract
BACKGROUND Mesenterico-portal vein resection (PVR) during pancreatoduodenectomy for pancreatic head cancer was established in the 1990s and can be considered a routine procedure in specialized centers today. True histopathologic portal vein invasion is predictive of poor prognosis. The aim of this study was to examine the relationship between mesenterico-portal venous tumor infiltration (PVI) and features of aggressive tumor biology. METHODS Patients receiving PVR for pancreatic ductal adenocarcinoma of the pancreatic head were identified from a prospectively maintained database. Immunohistochemical staining of tumor tissue was performed for the markers of epithelial-mesenchymal transition (EMT) E-Cadherin, Vimentin and beta-Catenin. Morphology of cancer-associated fibroblasts (CAFs) was assessed as inactive or activated. Statistical calculations were performed with MedCalc software. RESULTS In total, 41 patients could be included. Median overall survival was 25 months. PVI was found in 17 patients (41%) and was significantly associated with loss of membranous E-Cadherin in tumor buds (p = 0.020), increased Vimentin expression (p = 0.03), activated CAF morphology (p = 0.046) and margin positive resection (p = 0.005). CONCLUSION Our findings suggest that PVI is associated with aggressive tumor biology and disseminated growth less amenable to margin-negative resection.

Abstract
Locally advanced pancreatic cancer is associated with a very poor prognosis. This study was performed to evaluate whether patients with locally advanced pancreatic cancer benefit from (125)I seed implantation. This retrospective study included 224 patients with locally advanced pancreatic cancer, with 137 patients (61.2%) in the implantation (IP) group and 87 (38.9%) in the non-implantation (NIP) group. The survival status, complications and objective curative effects were compared between the groups. The average operative time in the IP group was significantly longer than that in the NIP group (243±51 vs. 214±77 min). The tumor response rates were 9.5% and 0 at the 2nd month after surgery in the IP and NIP groups, respectively (P<0.05). The IP group exhibited a trend toward pain relief at the 6th month after surgery. The global health status scores of the IP group were higher than those of the NIP group at the 3rd and 6th month after surgery. The median survival time in the IP group was significantly longer than that in the NIP group. In conclusion, patients with locally advanced pancreatic cancer can benefit from (125)I seed implantation in terms of local tumor control, survival time, pain relief and quality of life.

Br J Surg 2015; 103:179-91. [PMID: 26663252 DOI: 10.1002/bjs.9969] [Citation(s) in RCA: 121] [Impact Index Per Article: 13.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2015] [Revised: 08/27/2015] [Accepted: 09/15/2015] [Indexed: 01/06/2023]
Abstract
BACKGROUND Pancreatic ductal adenocarcinoma has a poor prognosis without surgery. No standard treatment has yet been accepted for patients with portal-superior mesenteric vein (PV-SMV) infiltration. The present meta-analysis aimed to compare the results of pancreatic resection with PV-SMV resection for suspected infiltration with the results of surgery without PV-SMV resection. METHODS A systematic search was performed of PubMed, Embase and the Cochrane Library in accordance with PRISMA guidelines from the time of inception to 2013. The inclusion criteria were comparative studies including patients who underwent pancreatic resection with or without PV-SMV resection. One, 3- and 5-year survival were the primary outcomes. RESULTS Twenty-seven studies were identified involving a total of 9005 patients (1587 in PV-SMV resection group). Patients undergoing PV-SMV resection had an increased risk of postoperative mortality (risk difference (RD) 0.01, 95 per cent c.i. 0.00 to 0.03; P = 0.2) and of R1/R2 resection (RD 0.09, 0.06 to 0.13; P < 0.001) compared with those undergoing standard surgery. One-, 3- and 5-year survival were worse in the PV-SMV resection group: hazard ratio 1.23 (95 per cent c.i. 1.07 to 1.43; P = 0.005), 1.48 (1.14 to 1.91; P = 0.004) and 3.18 (1.95 to 5.19; P < 0.001) respectively. Median overall survival was 14.3 months for patients undergoing pancreatic resection with PV-SMV resection and 19.5 months for those without vein resection (P = 0.063). Neoadjuvant therapies recently showed promising results. CONCLUSION This meta-analysis showed increased postoperative mortality, higher rates of non-radical surgery and worse survival after pancreatic resection with PV-SMV resection. This may be related to more advanced disease in this group.

Abstract
Pancreatic cancer (PDAC) is the fourth leading cause of cancer-related mortality in the Western world and, even in 2014, a therapeutic challenge. The only chance for long-term survival is radical surgical resection followed by adjuvant chemotherapy which can be performed in about 20% of all PDAC patients by the time of diagnosis. As pancreatic surgery has significantly changed during the past years, extended operations, including vascular resections, have become more frequently performed in specialized centres and the border of resectability has been pushed forward to achieve a potentially curative approach in the respective patients in combination with neoadjuvant and adjuvant treatment strategies. In contrast to adjuvant treatment which has to be regarded as a cornerstone to achieve long-term survival after resection, neoadjuvant treatment strategies for locally advanced findings are currently under debate. This overview summarizes the possibilities and evidence of vascular, namely, venous and arterial, resections in PDAC surgery.

Abstract
OBJECTIVE Vascular reconstruction can facilitate pancreas tumor resection, but optimal methods of reconstruction are not well studied. We report our results for portal vein reconstruction (PVR) for pancreatic resection and determinants of postoperative patency. METHODS We identified 173 patients with PVR in a prospective database of 6522 patients who underwent pancreatic resection at our hospital from 1970 to 2014. There were 128 patients who had >1 year of follow-up with computed tomography imaging. Preoperative, intraoperative, and postoperative factors were recorded. Patients with and without postoperative PVR thrombosis were compared by univariable, multivariable, and receiver operating characteristic curve analyses. RESULTS The survival of patients was 100% at 1 month, 88% at 6 months, 66% at 1 year, and 39% on overall median follow-up of 310 days (interquartile range, 417 days). Median survival was 15.5 months (interquartile range, 25 months); 86% of resections were for cancer. Four types of PVR techniques were used: 83% of PVRs were performed by primary repair, 8.7% with interposition vein graft, 4.7% with interposition prosthetic graft, and 4.7% with patch. PVR patency was 100% at 1 day, 98% at 1 month, 91% at 6 months, and 83% at 1 year. Patients with PVR thrombosis were not significantly different from patients with patent PVR in age, survival, preoperative comorbidities, tumor characteristics, perioperative blood loss or transfusion, or postoperative complications. They were more likely to have had preoperative chemotherapy (53% vs 9%; P < .0001), radiation therapy (35% vs 2%; P < .0001), and prolonged operative time (618 ± 57 vs 424 ± 20 minutes; P = .002) and to develop postoperative ascites (76% vs 22%; P < .001). Among patients who developed ascites, 38% of those with PVR thrombosis did so in the setting of tumor recurrence at the porta detected on imaging, whereas among patients with patent PVR, 50% did so (P = .73). Patients with PVR thrombosis were more likely to have had prosthetic graft placement compared with patients with patent PVRs (18% vs 2.7%; P = .03; odds ratio [OR], 7.7; 95% confidence interval [CI], 1.4-42). PVR patency overall was significantly worse for patients who had an interposition prosthetic graft reconstruction (log-rank, P = .04). On multivariable analysis, operative time (OR, 1.01; 95% CI, 1.01-1.02) and prosthetic graft placement (OR, 8.12; 95% CI, 1.1-74) were independent predictors of PVR thrombosis (C statistic = 0.88). CONCLUSIONS Long operative times and use of prosthetic grafts for reconstruction are risk factors for postoperative portal vein thrombosis. Primary repair, patch, or vein interposition should be preferentially used for PVR in the setting of pancreatic resection.

Abstract
BACKGROUND The aim of this study was to determine the added value of portal or superior mesenteric vein (PV/SMV) resection during pancreatoduodenectomy for pancreatic head carcinoma. METHODS A multicentre observational study was conducted in patients with pancreatic head carcinoma who underwent pancreatoduodenectomy in seven Japanese hospitals between 2001 and 2012. Clinicopathological factors were compared between patients who did and did not undergo PV/SMV resection. Those with an impact on survival were identified by univariable and multivariable analysis. RESULTS Of the 937 patients who underwent pancreatoduodenectomy, 435 (46·4 per cent) had PV/SMV resection, whereas the remaining 502 (53·6 per cent) did not. Some 71·5 and 63·9 per cent of patients with and without PV/SMV resection respectively had lymph node-positive disease. Patients who underwent PV/SMV resection had more advanced tumours. Perioperative mortality and morbidity rates did not differ between the two groups. Multivariable analysis revealed that PV/SMV resection was not an independent prognostic factor for overall survival (P = 0·268). Among the 435 patients in whom the PV/SMV was resected, borderline resectable tumours with arterial abutment (P = 0·021) and absence of adjuvant chemotherapy (P < 0·001) were independent predictors of poor survival in multivariable analysis. Patients with resectable or borderline resectable tumours with PV/SMV involvement had a median survival time with additional adjuvant chemotherapy of 43·7 and 29·7 months respectively. Median survival time in patients with borderline resectable tumours with arterial abutment was 18·6 months despite adjuvant chemotherapy. CONCLUSION Pancreatoduodenectomy with PV/SMV resection and adjuvant chemotherapy in patients with pancreatic head carcinoma may provide good survival without increased mortality and morbidity.

Abstract
BACKGROUND The fate of the portal vein (PV) after pancreatoduodenectomy, especially its long-term patency and associated complications, has received little attention. The aim of this study was to explore the long-term patency rate of the PV after pancreatoduodenectomy, focusing on risk factors for PV stenosis/occlusion and associated complications. METHODS Serial CT images of patients who underwent pancreatoduodenectomy for periampullary cancer between January 2000 and June 2012 in a single institution were evaluated for PV stenosis or occlusion. RESULTS A total of 826 patients were enrolled. The PV stenosis/occlusion rate after pancreatoduodenectomy was 19.6 per cent and the 5-year patency rate 69.9 per cent. The most frequent cause of PV stenosis/occlusion was local recurrence followed by postoperative change and PV thrombosis. Patients who underwent PV resection had a higher PV stenosis/occlusion rate than those who did not (51 versus 17.4 per cent; P < 0.001). The 3-year patency rate was highest in patients with cancer of the ampulla of Vater and lowest in patients with pancreatic cancer (91.9 versus 55.5 per cent respectively; P < 0.001). Multivariable analysis showed that risk factors for PV stenosis/occlusion included primary tumour location, chemoradiotherapy and PV resection. PV stenosis or occlusion without disease recurrence was observed in 17.3 per cent of the patients. PV resection and grade B or C pancreatic fistula were independent risk factors for PV stenosis/occlusion. Among 162 patients with PV stenosis or occlusion, five (3.1 per cent) had fatal recurrent gastrointestinal bleeding. CONCLUSION PV stenosis or occlusion is common after pancreatoduodenectomy, particularly if the PV has been resected and/or chemoradiotherapy was given after surgery. Although recurrence is the most frequent cause of PV stenosis/occlusion, this complication is found in a significant proportion of patients without disease recurrence.

Abstract
BACKGROUND The use of prosthetic grafts for superior mesenteric-portal vein reconstruction (SMPVR) after pancreaticoduodenectomy (PD) with venous resection remains controversial. We evaluated the effectiveness and safety of using polytetrafluoroethylene (PTFE) interposition grafts for SMPVR after PD. METHODS We identified 76 patients who underwent PD with segmental vein resection for pancreatic head and periampullary neoplasms at three centers between January 2007 and June 2012. The venous reconstruction technique depended on the length of venous involvement. Forty-two and 34 patients underwent SMPVR with primary anastomosis and SMPVR with PTFE interposition grafts, respectively. The postoperative morbidity, mortality, and patency were compared. For the patients with pancreatic ductal adenocarcinoma (n = 65), survival was compared between the SMPVR with primary anastomosis (n = 36) and SMPVR with PTFE interposition graft groups (n = 29). RESULTS Patients undergoing SMPVR with PTFE grafts had larger tumor sizes (3.4 ± 0.9 cm, 2.9 ± 0.9 cm, P = 0.016), longer operative durations (492.9 ± 107.5 min, 408.8 ± 78.8 min, P < 0.001), and greater blood loss (986.8 ± 884.5 ml, 616.7 ± 485.5 ml, P = 0.040) compared to those undergoing SMPVR with primary anastomosis. However, 30-day postoperative morbidity and mortality did not differ (29.4 and 2.9 %, respectively, for PTFE grafts and 33.3 and 7.1 %, respectively, for primary anastomosis). There were no cases of graft infection. The estimated cumulative patency of SMPVR 6 and 12 months after surgery did not differ (87.9 and 83.5 % after PTFE grafts, respectively, and 94.4 and 86.4 % after primary anastomosis, respectively). For patients who underwent surgery for pancreatic ductal adenocarcinoma, there were no significant differences in the median survival time (11 vs. 12 months) or the 1-, 2-, and 3-year survival rates (35.7, 12.5, and 4.2 vs. 36.4, 17.3, and 8.7 %, respectively) for the PTFE and primary anastomosis groups. CONCLUSIONS PTFE grafts could provide a safe and effective option for venous reconstruction after PD in patients with segmental vein resection.

Abstract
This literature review aimed to critically analyze oncological results of vascular resection during pancreatectomy for adenocarcinoma in the light of the concept evolution of locally advanced tumors and microscopic complete resection. The literature search was conducted in PubMed and Medline for the period June 1994 to December 2012, retaining English as the language of publication. The review of 12 publications indicated that mortality and morbidity rates were not significantly different for pancreatectomy with or without venous resection (VR). Six comparative studies showed worse long-term survival in the VR group, though one meta-analysis, albeit with a significant population heterogeneity, demonstrated that the overall survival between VR and the control group was similar (12% vs. 17%). The compilation of 13 comparative studies showed a significantly lower rate of complete microscopic resection in the VR patient group compared to controls (63% vs. 77%; P = 0.001). Concerning pancreatectomy combined to arterial resection, the literature review indicated a significantly greater mortality and morbidity rate and a lower survival rate compared to pancreatic resection alone. Conflicting results concerning the long-term outcome of VR was due to the heterogeneity of the patient population. Since the only chance to cure patients of pancreatic adenocarcinoma is to obtain free resection margins, VR is a valid therapeutic option. But combined arterial resection to pancreatic resection does not appear to be recommended.

Abstract
As surgical resection remains the only hope for cure in pancreatic cancer (PC), more aggressive surgical approaches have been advocated to increase resection rates. Venous resection demonstrated to be a feasible technique in experienced centers, increasing survival. In contrast, arterial resection is still an issue of debate, continuing to be considered a general contraindication to resection. In the last years there have been significant advances in surgical techniques and postoperative management which have dramatically reduced mortality and morbidity of major pancreatic resections. Furthermore, advances in multimodal neo-adjuvant and adjuvant treatments, as well as the better understanding of tumor biology and new diagnostic options have increased overall survival. In this article we highlight some of the important points that a modern pancreatic surgeon should take into account in the management of PC with arterial involvement in light of the recent advances.

Abstract
BACKGROUND Pancreaticoduodenectomy combined with portal-superior mesenteric vein synchronous resection for cancer remains a hot debate topic. The present study used meta-analytical technique to provide update information and an evidence-based evaluation on both the perioperative benefit and long-term survival. METHODS A meta-analysis was performed to evaluate studies comparing venous resection (VR) versus without venous resection (WVR) groups. 22 retrospective studies including 2890 patients were eligible for an analysis of perioperative morbidity, mortality, and long-term survival. Furthermore, subgroup analysis was made according to histopathology and resection margin status respectively for the purpose of survival assessment. RESULTS There was no difference in perioperative morbidity, mortality and 1-year, 3-year survival between two groups, but showed differences in median tumor size (P < 0.001), R0 resection rate (P < 0.001), lymph node metastasis (P = 0.03), pancreatic fistula (P = 0.01), and 5-year survival (P = 0.03). In subgroup analysis, patients in venous resection group received R0 resection had a significantly better survival comparing with who received R1 resection both at 2-year (P < 0.001) and 5-year (P = 0.00002). In histopathology subgroup, patients in venous resection groups who had true tumor infiltration had a significantly bad survival comparing with whom only with inflammation pathology. CONCLUSION Pancreaticoduodenectomy combined with venous resection can achieve equal perioperative morbidity and mortality as standard resection. However, in order to obtain an optimal survival outcome, surgeons should make an R0 resection as far as possible, especially in cases need synchronous venous resection.

Abstract
BACKGROUND To assess the efficacy of intraoperative ultrasound-guided implantation of 125I seeds for the treatment of unresectable pancreatic carcinoma, and analyze the associated prognostic factors. METHODS Twenty-eight patients with pancreatic carcinoma who underwent laparotomy and were considered to have unresectable tumors were included in this study. Nine patients were pathologically diagnosed with Stage II disease, and nineteen patients with Stage III disease. Twenty-eight patients received intraoperative ultrasound-guided 125I seed implantation and received a D90 (at least 90% of the tumor volume received the reference dose) ranging from 60 to 163 Gy, with a median of 120 Gy. Seven patients received an additional 35-50 Gy external beam radiotherapy after seed implantation, and ten patients received two to ten cycles of chemotherapy. Overall survival of the patients was calculated and prognostic factors were evaluated. RESULTS Of the patients, 94.1% (16/17) achieved good to medium pain relief. The tumor response rate was 78.6% (22/28), and local control was achieved in 85.7% (24/28) of patients. The 1-, 2- and 3-year survival rates were 30%, 11% and 4%, and the median survival was 10.1 months (95% CI: 9.0-10.9). Analysis using the Cox proportional hazards model suggested that patients younger than 60 years and patients who received a D90 higher than 110 Gy may survive for a longer period. CONCLUSIONS I seed implantation provides a safe and effective method to relieve pain, control local tumor growth and, to some extent, prolong the survival of patients with stage II and III pancreatic disease, without additional complications. Age and accumulated dose may be factors predictive of a favorable outcome for patients with unresectable pancreatic carcinoma treated with 125I seeds. These findings need to be validated by conducting further studies with larger cohorts.

Abstract
Objective The aim of this study was to present the therapeutic outcome of patients with locally advanced pancreatic cancer treated with pancreatoduodenectomy combined with vascular resection and reconstruction in addition to highlighting the mortality/morbidity and main prognostic factors associated with this treatment. Materials and Methods We retrospectively analyzed the clinical and pathological data of a total of 566 pancreatic cancer patients who were treated with PD from five teaching hospitals during the period of December 2006–December 2011. This study included 119 (21.0%) patients treated with PD combined with vascular resection and reconstruction. We performed a detailed statistical analysis of various factors, including postoperative complications, operative mortality, survival rate, operative time, pathological type, and lymph node metastasis. Results The median survival time of the 119 cases that received PD combined with vascular resection was 13.3 months, and the 1-, 2-, and 3-year survival rates were 30.3%, 14.1%, and 8.1%, respectively. The postoperative complication incidence was 23.5%, and the mortality rate was 6.7%. For the combined vascular resection group, complications occurred in 28 cases (23.5%). For the group without vascular resection, complications occurred in 37 cases (8.2%). There was significant difference between the two groups (p = 0.001). The degree of tumor differentiation and the occurrence of complications after surgery were independent prognostic factors that determined the patients’ long-term survival. Conclusions Compared with PD without vascular resection, PD combined with vascular resection and reconstruction increased the incidence of postoperative complications. However, PD combined with vascular resection and reconstruction could achieve the complete removal of tumors without significantly increasing the mortality rate, and the median survival time was higher than that of patients who underwent palliative treatment. In addition, the two independent factors affecting the postoperative survival time were the degree of tumor differentiation and the presence or absence of postoperative complications.

Abstract
Pancreatic adenocarcinoma is the most common pancreatic malignancy, and it occurs most commonly in the pancreatic head. It has a relatively low incidence; however it is a deadly disease and is the fourth most common cause of cancer deaths for males and females in the United States. Surgical resection in the form of pancreaticoduodenectomy is the mainstay of treatment and can lead to improved overall survival as well as the possibility of a cure, although only 10 % of patients are resectable at presentation. In an attempt to improve outcomes and survival, surgeons over the decades have employed various aggressive resectional strategies to combat this disease. In this paper we review the development of pancreaticoduodenectomy and touch on the role played by the American surgeon Allan Whipple in this development. We review modern data regarding radical pancreaticoduodenectomy and extended lymphadenectomy for pancreatic head cancers, as well as data and controversies regarding arterial and venous resection performed during the course of pancreaticoduodenectomy. The role of extended and vascular resections in the treatment of pancreatic neuroendocrine tumors in contrast to adenocarcinomas is also examined. We summarize the current state of data regarding radical pancreaticoduodenectomy and discuss pushing the boundaries of surgical resection to help improve outcomes for select groups of patients.

Abstract
Pancreatic cancer is the fourth leading cause of cancer related deaths in the United States. The prognosis remains dismal with little advance in treatment. Metformin is a drug widely used for the treatment of type II diabetes. Recent epidemiologic data revealed that oral administration of metformin is associated with a reduced risk of pancreatic cancer, suggesting its potential as a novel drug for this disease. Many studies have demonstrated the in vitro anticancer action of metformin, but the typically used concentrations were much higher than the in vivo plasma and tissue concentrations achieved with recommended therapeutic doses of metformin, and low concentrations of metformin had little effect on the proliferation of pancreatic cancer cells. We examined the effect of low concentrations of metformin on different subpopulations of pancreatic cancer cells and found that these selectively inhibited the proliferation of CD133+ but not CD24+CD44+ESA+ cells. We also examined the effect of low concentrations of metformin on cell invasion and in vivo tumor formation, demonstrating in vitro and in vivo anticancer action. Metformin was associated with a reduction of phospho-Erk and phospho-mTOR independent of Akt and AMPK phosphorylation. CD133+ pancreatic cancer cells are considered to be cancer stem cells that contribute to recurrence, metastasis and resistance to adjuvant therapies in pancreatic cancer. Our results provide a basis for combination of metformin with current therapies to improve the prognosis of this disease.

Benefit of portal or superior mesenteric vein resection with adjuvant chemotherapy for patients with pancreatic head carcinoma. J Surg Oncol 2012; 107:414-21.

Abstract
BACKGROUND AND OBJECTIVES The aim of this study was to evaluate the efficacy of portal or superior mesenteric vein (PV/SMV) resection for patients with pancreatic carcinoma who underwent pancreatoduodenectomy. METHODS Medical records of 125 patients with pancreatic head carcinoma who underwent pancreatoduodenectomy were reviewed retrospectively. Sixty-one patients underwent PV/SMV resection and 64 patients did not. Clinicopathological factors were compared between the two groups and the prognostic impact of PV/SMV resection was evaluated using univariate and multivariate survival analysis. RESULTS The frequency of mortality and morbidity did not differ between the two groups. Univariate analysis revealed that a significant difference in overall survival was found between patients who did and did not undergo PV/SMV resection (P = 0.046) as well as between patients with and without pathological PV/SMV invasion (P = 0.012). However, PV/SMV resection and pathological PV/SMV invasion were not independent prognostic factors by multivariate survival analysis. Among patients with PV/SMV resection, the use of adjuvant chemotherapy was the only independent prognostic factor of overall survival (P = 0.003). CONCLUSIONS Resection of the PV/SMV with adjuvant chemotherapy may provide an acceptable survival benefit to patients with pancreatic head carcinoma, which involves the PV/SMV without additional mortality and morbidity.

Abstract
BACKGROUND The majority of pancreatic cancers are diagnosed at an advanced stage. As surgical resection remains the only hope for cure, more aggressive surgical approaches have been advocated to increase resection rates. Institutions have begun to release data on their experience with pancreatectomy and simultaneous arterial resection (AR), which has traditionally been considered a general contraindication to resection. The aim of the present meta-analysis was to evaluate the perioperative and long-term outcomes of patients with AR during pancreatectomy for pancreatic cancer. METHODS The Medline, Embase, and Cochrane Library and J-East databases were systematically searched to identify studies reporting outcome of patients who underwent pancreatectomy with AR for pancreatic cancer. Studies that reported perioperative and/or long-term results after pancreatectomy with AR were eligible for inclusion. Meta-analyses included comparative studies providing data on patients with and without AR and were performed using a random effects model. RESULTS The literature search identified 26 studies including 366 and 2243 patients who underwent pancreatectomy with and without AR. All studies were retrospective cohort studies and the methodological quality was moderate to low. Meta-analyses revealed AR to be associated with a significantly increased risk for perioperative mortality [Odds ratio (OR) = 5.04; 95% confidence interval (CI), 2.69-9.45; P < 0.0001; I² = 24%], poor survival at 1 year (OR = 0.49; 95% CI, 0.31-0.78; P = 0.002; I² = 35%) and 3 years (OR = 0.39; 95% CI, 0.17-0.86; P = 0.02; I² = 49%) compared with patients without AR. The increased perioperative mortality (OR = 8.87; 95% CI, 3.40-23.13; P < 0.0001; I² = 5%) and lower survival rate at 1 year (OR = 0.50; 95% CI, 0.31-0.82; P = 0.006; I² = 40%) was confirmed in the comparison to patients undergoing venous resection. Despite substantial perioperative mortality, pancreatectomy with AR was associated with more favorable survival compared with patients who did not undergo resection for locally advanced disease. CONCLUSIONS AR in patients undergoing pancreatectomy for pancreatic cancer is associated with a poor short and long-term outcome. Pancreatectomy with AR may, however, be justified in highly selected patients owing to the potential survival benefit compared with patients without resection. These patients should be treated within the bounds of clinical trials to assess outcomes after AR in the era of modern pancreatic surgery and multimodal therapy.

Abstract
OBJECTIVES This systematic review objectively evaluates the safety and outcomes of extended pancreaticoduodenectomy with vascular resection for pancreatic cancer involving critical adjacent vessels namely the superior mesenteric-portal veins, hepatic artery, superior mesenteric artery, and celiac axis. METHODS Electronic searches were performed on two databases from January 1995 to August 2009. The end points were: firstly, to evaluate the safety through reporting the mortality rate and associated complications and, secondly, the outcome by reporting the survival after surgery. This was synthesized through a narrative review with full tabulation of results of all included studies. RESULTS Twenty-eight retrospective studies comprising of 1,458 patients were reviewed. Vein thrombosis and arterial involvement were reported as contraindications to surgery in 62% and 71% of studies, respectively. The median mortality rate was 4% (range, 0% to 17%). The median R0 and R1 rates were 75% (range, 14% to 100%) and 25% (range, 0% to 86%), respectively. In high volume centers, the median survival was 15 months (range, 9 to 23 months). Nine of 10 (90%) studies comparing the survival after extended pancreaticoduodenectomy with vascular resection versus standard pancreaticoduodenectomy reported statistically similar (p > 0.05) survival outcomes. Undertaking vascular resection was not associated with a poorer survival. CONCLUSIONS The morbidity, mortality, and survival outcome after undertaking extended pancreaticoduodenectomy with vascular resection for pancreatic cancer with venous involvement and/or limited arterial involvement is acceptable in the setting of an expert referral center and should not be a contraindication to a curative surgery.

Abstract
BACKGROUND/PURPOSE We often encounter unresectable pancreatic cancer due to invasions of the major vessels. Vascular resection for locally advanced pancreatic cancers has an advantage in en block local resection. There are potential cases in which good outcomes can be achieved by arterial resection. METHODS Pancreatectomy (including total pancreatectomy in 15 cases, pancreatoduodenectomy in 7 cases and distal pancreatectomy in one case) was performed in 23 cases of invasive ductal carcinoma of the pancreas, in combination with resection and reconstruction of the hepatic artery in 15 cases, the superior mesenteric artery in 12 cases (there are overlaps) and the portal vein in 20 cases. RESULTS The median operating time was 686 min (416-1,190 min) and the median blood loss was 2,830 ml (440-19,800 ml). This shows that the surgery was highly-invasive. The operative mortality rate was 4.3%. On the basis of the UICC classification, there were 2 cases of Stage IIa, 4 cases of Stage IIb, 9 cases of Stage III, 8 cases of Stage IV, while there were 18 cases (78.3%) of R0 resection. On the other hand, the final histological findings showed that there were 8 cases (34.8%) of M1 (liver and non-regional lymph node metastases), so it is thought that decisions on operative indications should be not be made slightly. As for the overall survival rate, the 1-year survival rate was 51.2% and the 3-year survival rate was 23.1% while the median survival time (MST) was 12 months. As for 15 cases of M0, the 1-year survival rate was 61.9% and the 4-year survival rate was 38.7% while the MST was 16 months. On the other hand, the MST was poor (10 months) in 8 cases of M1, showing that a statistically significant difference was observed depending upon the degree of metastasis (log-rank P = 0.0409). In 18 cases of R0, the 1-year survival rate was 67.2%, the 4-year survival rate 30.2% and the MST 13 months, respectively, while in 5 cases of R1 and R2, the MST was 6 months, showing that there was a statistically significant difference between R0 cases and R1, R2 cases (log-rank P = 0.0002). CONCLUSIONS Further discussion is required concerning surgical indications and significance. However, it is thought that resection is useful only when surgery of R0 has taken place for selected locally advanced pancreatic cancer (M0).

Abstract
BACKGROUND The most accepted treatment for locally advanced pancreatic adenocarcinoma (LAPA) is chemoradiotherapy (CRT). We sought to determine the benefit of pancreaticoduodenectomy (PD) in patients with LAPA initially treated by neoadjuvant CRT. METHODS From January 1996 to December 2006, 64 patients with LAPA (borderline, n=49; unresectable, n=15) received 5-fluorouracil-cisplatin-based CRT. Of the 64 patients, 47 had progressive disease at restaging. Laparotomy was performed for 17 patients, and PD was performed in 9 patients (resected group). Fifty-five patients had CRT followed by gemcitabine-based chemotherapy (unresected group). RESULTS The median survival and overall 5 years survival duration of all 64 patients were 14 months and 12%, respectively. The mean delay between diagnosis and surgical resection was 5.5 months. Mortality and morbidity from PD were 0% and 33%, respectively. The median survival of the resected group vs. the unresected group was 24 months vs. 13 months. Three specimens presented a major pathological response at histological examination. No involved margins were found and positive lymph nodes were found in one patient. Resected patients developed distant metastases. CONCLUSIONS PD after CRT was safe and resected patients had interesting survival rates. However, resected patients developed metastatic disease and new neoadjuvant regimens are needed to improve the survival of these patients.
