Abstract
BACKGROUND In patients with hepatic artery variation (HAV), feasibility and justification of robotic pancreatoduodenectomy (RPD) for periampullary lesions have been not been well established. METHODS A total of 600 patients with periampullary lesions receiving RPD or open pancreaticoduodenectomy (OPD) were identified from our prospectively collected computer database. Surgical outcomes, oncological radicality, and survival outcomes after RPD in HAV ( +) and (-) patients were compared. RESULTS The incidence of HAV was 16%, including 12.7% in patients with RPD and 23.0% in those with OPD. In the HAV ( +) group, vascular injury rate had no statistical difference between the RPD (3.7%) and OPD (9.1%) patients, P = 0.404. Among the RPD patients, those with HAV ( +) had longer operation time (8.5 ± 2.5 vs. 7.7 ± 2.0 h, P = 0.013) and higher vascular injury (3.8% vs. 0.6%, P = 0.024) when compared with the HAV (-) patients. There was no significant difference between the HAV ( +) and (-) patients with RPD regarding blood loss, open conversion, vascular resection, and surgical mortality and morbidity. There was no survival difference between the HAV ( +) and (-) patients with pancreatic head adenocarcinoma after RPD. There was no survival difference between RPD and OPD in the HAV ( +) group. CONCLUSIONS When compared with OPD, RPD is feasible and justifiable without increasing vascular injury rate for patients with HAV ( +). Hepatic artery variation has no negative impact on surgical, oncological, and survival outcomes following an RPD, if it is accurately identified pre-operatively and appropriately managed intraoperatively.

[PMID: 37925285 DOI: 10.1016/j.asjsur.2023.10.076] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 09/06/2023] [Accepted: 10/20/2023] [Indexed: 11/06/2023] Open
Abstract
BACKGROUND/OBJECTIVE Robotic pancreaticoduodenectomy in ampullary cancer has never been studied. This study aimed to clarify the feasibility and justification of robotic pancreaticoduodenectomy in ampullary cancer in terms of surgical risks, and oncologic and survival outcomes. METHODS A propensity score-matching comparison of robotic and open pancreaticoduodenectomy based on seven factors commonly used to predict the survival outcomes in ampullary cancer patients. RESULTS A total of 147 patients were enrolled, of which 101 and 46 underwent robotic and open pancreaticoduodenectomies, respectively. After propensity score-matching with a 2:1 ratio, 88 and 44 patients in the robotic and open pancreaticoduodenectomy groups were included. The operation time was of no significant difference after matching. The median intraoperative blood loss was much less in those who underwent robotic pancreaticoduodenectomy, both before (median, 120 vs. 320 c.c. P < 0.001) and after (100 vs. 335 mL P < 0.001) score-matching. There were no significant differences in terms of surgical risks, including surgical mortality, surgical morbidity, Clavien-Dindo severity classification, postoperative pancreatic fistula, delayed gastric emptying, post-pancreatectomy hemorrhage, chyle leak, bile leak, and wound infection, both before or after score-matching. The survival outcomes were also similar between the two groups, regardless of matching. CONCLUSIONS Robotic pancreaticoduodenectomy for ampullary cancer is not only technically feasible and safe without increasing surgical risks, but also oncologically justifiable without compromising surgical radicality and survival outcomes.

Currently Debated Topics on Surgical Treatment of Pancreatic Ductal Adenocarcinoma: A Narrative Review on Surgical Treatment of Borderline Resectable, Locally Advanced, and Synchronous or Metachronous Oligometastatic Tumor. J Clin Med 2023; 12:6461.

Abstract
BACKGROUND Previously considered inoperable patients (borderline resectable, locally advanced, synchronous oligometastatic or metachronous pancreatic adenocarcinoma (PDAC)) are starting to become resectable thanks to advances in chemo/radiotherapy and the reduction in operative mortality. METHODS This narrative review presents a chosen literature selection, giving a picture of the current state of treatment of these patients. RESULTS Neoadjuvant therapy (NAT) is generally recognized as the treatment of choice before surgery. However, despite the increased efficacy, the best pathological response is still limited to 10.9-27.9% of patients. There are still limited data on the selection of possible NAT responders and how to diagnose non-responders early. Multidetector computed tomography has high sensitivity and low specificity in evaluating resectability after NAT, limiting the resection rate of resectable patients. Ca 19-9 and Positron emission tomography are giving promising results. The prediction of early recurrence after a radical resection of synchronous or metachronous metastatic PDAC, thus identifying patients with poor prognosis and saving them from a resection of little benefit, is still ongoing, although some promising data are available. CONCLUSION In conclusion, high-level evidence demonstrating the benefit of the surgical treatment of such patients is still lacking and should not be performed outside of high-volume centers with interdisciplinary teams of surgeons and oncologists.

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.

Ligamentum teres hepatis as a graft for portal and/or superior mesenteric vein reconstruction: From bench to bedside. World J Gastrointest Surg 2023; 15:674-686. [PMID: 37206073 PMCID: PMC10190722 DOI: 10.4240/wjgs.v15.i4.674] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 02/06/2023] [Accepted: 03/16/2023] [Indexed: 04/22/2023] Open
Abstract
BACKGROUND Pancreaticoduodenectomy combined with portal vein (PV) and/or superior mesenteric vein (SMV) resection in patients with pancreaticobiliary malignancy has become a common surgical procedure. There are various grafts currently used for PV and/or SMV reconstruction, but each of these grafts have certain limitations. Therefore, it is necessary to explore novel grafts that have an extensive resource pool, are low cost with good clinical application, and are without immune response rejection or additional damage to patients.
AIM To observe the anatomical and histological characteristics of the ligamentum teres hepatis (LTH) and evaluate PV/SMV reconstruction using an autologous LTH graft in pancreaticobiliary malignancy patients.
METHODS In 107 patients, the post-dilated length and diameter in resected LTH specimens were measured. The general structure of the LTH specimens was observed by hematoxylin and eosin (HE) staining. Collagen fibers (CFs), elastic fibers (EFs), and smooth muscle (SM) were visualized by Verhoeff-Van Gieson staining, and the expression of CD34, factor VIII-related antigen (FVIIIAg), endothelial nitric oxide synthase (eNOS), and tissue type plasminogen activator (t-PA) were detected using immunohistochemistry in LTH and PV (control) endothelial cells. PV and/or SMV reconstruction using the autologous LTH was conducted in 26 patients with pancreaticobiliary malignancies, and the outcomes were retrospectively analyzed.
RESULTS The post-dilated length of LTH was 9.67 ± 1.43 cm, and the diameter at a pressure of 30 cm H2O was 12.82 ± 1.32 mm at the cranial end and 7.06 ± 1.88 mm at the caudal end. Residual cavities with smooth tunica intima covered by endothelial cells were found in HE-stained LTH specimens. The relative amounts of EFs, CFs and SM in the LTH were similar to those in the PV [EF (%): 11.23 ± 3.40 vs 11.57 ± 2.80, P = 0.62; CF (%): 33.51 ± 7.71 vs 32.11 ± 4.82, P = 0.33; SM (%): 15.61 ± 5.26 vs 16.74 ± 4.83, P = 0.32]. CD34, FVIIIAg, eNOS, and t-PA were expressed in both LTH and PV endothelial cells. The PV and/or SMV reconstructions were successfully completed in all patients. The overall morbidity and mortality rates were 38.46% and 7.69%, respectively. There were no graft-related complications. The postoperative vein stenosis rates at 2 wk, 1 mo, 3 mo and 1 year were 7.69%, 11.54%, 15.38% and 19.23%, respectively. In all 5 patients affected, the degree of vascular stenosis was less than half of the reconstructed vein lumen diameter (mild stenosis), and the vessels remained patent.
CONCLUSION The anatomical and histological characteristics of LTH were similar to the PV and SMV. As such, the LTH can be used as an autologous graft for PV and/or SMV reconstruction in pancreaticobiliary malignancy patients who require PV and/or SMV resection.

Abstract
BACKGROUND Open pancreaticoduodenectomy (OPD) with portal or superior mesenteric vein resection and reconstruction has been applied in pancreatic cancer patients with tumor infiltration or adherence. However, it is controversial whether laparoscopic pancreaticoduodenectomy (LPD) with major vascular resection and reconstruction is feasible. This study aimed to evaluate the safety and feasibility of LPD with major vascular resection compared with OPD with major vascular resection. METHODS We reviewed data for all pancreatic cancer patients undergoing LPD or OPD with vascular resection at Department of Pancreatic Surgery, Fudan University Shanghai Cancer Center, between February 2018 and May 2022. We compared the preoperative, intraoperative, and postoperative clinicopathological data of the two groups to conduct a comprehensive evaluation of LPD with major vascular resection. RESULTS A total of 63 patients underwent pancreaticoduodenectomy (PD) with portal or superior mesenteric vein resection and reconstruction, including 25 LPDs and 38 OPDs. The LPD group had less intraoperative blood loss (200 vs. 400 mL, P < 0.001), lower proportion of intraoperative blood transfusion (16.0% vs. 39.5%, P = 0.047), longer operation time (390 vs. 334 min, P = 0.004) and shorter postoperative hospital stay (11 vs. 14 days, P = 0.005). There was no perioperative death in all patients. There was no significant difference in the incidence of total postoperative complications, grade B/C postoperative pancreatic fistula, delayed gastric emptying and abdominal infection between the two groups. No postpancreatectomy hemorrhage nor bile leakage occurred during perioperative period. There was no significant difference in R0 resection rate and number of lymph nodes harvested between the two groups. Patency of reconstructed vessels in the two groups were 96.0% and 92.1%, respectively (P = 0.927). CONCLUSIONS LPD with portal or superior mesenteric vein resection and reconstruction was safe, feasible and oncologically acceptable for selected patients with pancreatic cancer, and it can achieve similar or even better perioperative results compared to open approach.

Abstract
Background: Pancreaticoduodenectomy (PD) is a complex operative procedure, which remains the primary curative treatment for pancreatic, distal bile duct, and periampullary cancers. In recent years, with the continuous development of laparoscopic technology and equipment, laparoscopic pancreaticoduodenectomy (LPD) has been performed gradually in many high-volume surgical centers. However, it is still challenging even for experienced pancreatic surgeons to perform LPD, at the same time, with the accumulation of surgical experience, different surgical approaches are also constantly discussed. Methods: We retrospectively analyzed the clinical data of 323 patients who received LPD at a single institution. Among them, 200 patients received operations with retrocolic approach, 123 patients were treated with traditional approach. In this study, we analyzed perioperative data and compared survival time for patients with pancreatic cancers in two groups. Result: Compared with traditional approach, retrocolic approach with uncinate process priority has a shorter operative time (94.25 ± 6.46 minutes versus 116.43 ± .4.78 minutes, P = .009) and less intraoperative blood loss (80 mL versus 150 mL, P = .562). However, there is no statistical significance in the incidence of postoperative complications (≥ Clavien-Dindo [CD] III) (65 [32.5%] versus 45 [36.58%], P = .871), R0 resection rates (41 versus 38, P = .826), and the number of lymph nodes harvested (16.64 ± 5.93 versus 15.37 ± 4.65, P = .785) between two groups. Meanwhile, the median survival time of patients with pancreatic cancers in posterior approach group was longer than those in traditional approach group (30.34 months versus 28.54 months, P > .05); however, there was no statistical significance between them. Conclusion: Retrocolic approach with uncinate process priority is a feasible method for pancreatic cancer, which could reduce operating time and intraoperative bleeding, meanwhile, not increase the incidence of postoperative complications. Retrocolic approach with uncinate process priority can be generalized to larger group sizes.

Prognostic Value of Neoadjuvant Chemotherapy in Patients with Borderline Resectable Pancreatic Carcinoma Followed by Pancreatectomy with Portal Vein Resection and Reconstruction with Venous Allograft. J Clin Med 2022; 11:jcm11247380. [PMID: 36555996 PMCID: PMC9787949 DOI: 10.3390/jcm11247380] [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: 11/09/2022] [Revised: 11/29/2022] [Accepted: 12/10/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Neo-adjuvant chemotherapy (NAC) represents one of the current research hotspots in the field of pancreatic ductal adenocarcinoma (PDAC). The aim of this study is to evaluate the prognostic value of NAC in patients with borderline resectable pancreatic cancer (BRPC) followed by pancreatectomy with portal vein (PV) resection and reconstruction with venous allograft (VAG). METHODS Medical records of patients with BPRC who underwent pancreatectomy with concomitant PV resection and reconstruction with VAG between April 2013 and March 2021 were analyzed retrospectively. Outcomes of patients with and without NAC (NAC, Group 1 vs. non-NAC, Group 2) were compared with focus on R0 resection rates, morbidity, and survival. RESULTS Of the 77 patients with pancreatectomy, PV resection and reconstruction with VAG were identified. Overall survival (OS) rates of 0.5-, 1-, and 2-year were 80.5%, 59.7%, and 31.2%, respectively (median survival time, MST, 14 months). Of these, 24 patients (Group 1) underwent operation following received NAC, and the remaining 53 patients did not (Group 2). The R0 resection rate of vascular margin was 100% vs. 84.9% (p = 0.04), respectively. Morbidity of post-operative pancreatic fistula (POPF) was 0% vs. 17.8% (p = 0.07), respectively. The OS of 0.5-, 1- and 2-year and MST of 2 groups were 83.3%, 66.7%, 41.7%, 16 months, and 79.2%, 55.6%, 26.4%, 13 months, respectively. Multivariate analysis revealed that carbohydrate antigen 19-9 (CA19-9) serum level and postoperative chemotherapy were independent prognostic factors in patients with BRPC after surgery. CONCLUSION NAC might improve the R0 resection rate and POPF in patients with BRPC who underwent pancreatectomy with concomitant PV resection and reconstruction with VAG. Survival benefit exists in patients with BRPC who received NAC before pancreatectomy. Postoperative chemotherapy also had a favorable effect on OS of BRPC patients. Elevated CA 19-9 serum level is associated with poor prognosis, even after NAC-combining operation.

Abstract
BACKGROUND This study aimed to clarify the feasibility and justification of pancreatic head sparing (PHS) enucleation for patients with agenesis of the dorsal pancreas (ADP) associated with a solid pseudopapillary tumor (SPT). METHODS Data of the SPT patients with and without ADP, including clinical presentations, surgical options, and surgical and survival outcomes, were recruited for comparison. RESULTS A total of 31 patients with SPTs were included, three of whom displayed ADP and underwent PHS enucleation. Surgical complications were comparable between the groups. Overall, the 5- and 10-year disease-free survival rates were 100% and 90%, respectively. The 20- and 25-year overall survival rates were 100% and 66.7%, respectively. Only one patient (3.2%) developed tumor recurrence 7.3 years after pancreatectomy for an SPT with lymph node involvement, and the patient survived 24.5 years after the initial operation. No tumor recurrence occurred in any patient with ADP after PHS enucleation. CONCLUSION PHS enucleation seems to be feasible and justifiable for SPT patients with ADP in terms of surgical and survival outcomes, and this approach could be recommended to avoid pancreatic insufficiency.

Portal Vein Thrombosis After Venous Reconstruction During Pancreatectomy: Timing and Risks. J Gastrointest Surg 2022; 26:2148-2157. [PMID: 35819666 DOI: 10.1007/s11605-022-05401-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Accepted: 06/17/2022] [Indexed: 02/01/2023]
Abstract
BACKGROUND Numerous studies have shown that portal vein resection during pancreatectomy can help achieve complete tumor clearance and long term-survival. While the safety of vascular resection during pancreatectomy is well documented, the risk of superior mesenteric vein/portal vein (SMV/PV) thrombosis after reconstruction remains unclear. This study aimed to describe the incidence and risk factors of SMV/PV thrombosis after vein reconstruction during pancreatectomy. METHODS All patients who underwent portal vein resection (PVR) during pancreatectomy (2007-2019) were identified from a single institution prospective clinical database. Demographic and clinical data, operative and pathological findings, and postoperative outcomes were analyzed. RESULTS Pancreatectomy with PVR was performed in 220 patients (mean age 65.1 years, male/female ratio 0.96). Thrombosis occurred in 36 (16.4%) patients after a median of 15.5 days [IQR 38.5, 1-786 days]. SMV/PV patency rates were 92.7% and 88.7% at 1 and 3 months, respectively. The rate of SMV/PV thrombosis varied according to SMV/PV reconstruction technique: 12.8% after venorrhaphy, 13.2% end-to-end anastomosis, 22.6% autologous vein, and 83.3% synthetic graft interposition (p < 0.0001). SMV/PV thrombosis was associated with increased 90-day mortality (16.7% vs 4.9%, p = 0.02) and overall 30-day complication rate (69.4% vs 42.9%, p = 0.006). Pancreatectomy type, neoadjuvant chemoradiation, pathologic tumor venous invasion, resection margin status, and manner of perioperative anticoagulation did not influence the incidence of PV thrombosis. SMV/PV thrombosis was associated with a nearly 5-times increased risk of postoperative sepsis after pancreatectomy. CONCLUSION Portal vein thrombosis developed in 16% of patients who underwent pancreatectomy with PVR at a median of 15 days. PVR with synthetic interposition graft carries the highest risk for thrombosis.

Patency for autologous vein is superior to cadaveric vein in portal-mesenteric venous reconstruction. HPB (Oxford) 2022; 24:1326-1334. [PMID: 35135725 DOI: 10.1016/j.hpb.2022.01.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Revised: 01/03/2022] [Accepted: 01/14/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND Portal venous reconstruction (PVR) is often needed during resection of hepatopancreato-biliary (HPB) malignancies. Primary repair (PR), autologous vein (AV), or cryopreserved cadaveric vein (CCV) are frequently utilized, however relative patency is not well studied. METHODS All patients undergoing PVR between 2007-2019 at our center were identified. 3-year primary patency (PP), overall survival (OS), and survival-adjusted patency (SAP) were evaluated with Kaplan-Meier and Cox proportional hazards modeling. RESULTS One-hundred-twenty patients were identified with a median follow-up of 11 months. PR, AV, and CCV reconstruction were used in 28 (23%), 35 (29%), and 57 (48%) patients, respectively, with two (7%), four (11%), and 29 (51%) thromboses, respectively. 3-year PP was greater for both primary repair (90%) and AV (83%) compared to CCV (33%, both p<0.001). On multivariable analysis, CCV had worse 3-year PP (HR 7.89, p=0.005) and SAP (HR 2.09, p=0.02) compared to PR; AV reconstruction had equivalent oncologic and patency-related outcomes to PR (p>0.4 for both comparisons). CONCLUSIONS Primary patency for PR and AV reconstruction is superior to CCV for PVR during resection of HPB malignancies. AV conduit should be the preferred choice of reconstruction when PR is not achievable. Surgeons should only use CCV when factors preclude PR/AV reconstruction.

Abstract
Background and Aims There is no consensus on the superiority of robotic distal pancreatectomy (RDP) over laparoscopic distal pancreatectomy (LDP). Methods Data of patients undergoing RDP and LDP were prospectively collected and compared. Results There were 65 RDP and 112 LDP. RDP took a shorter operation time than LDP. Overall, DP with splenectomy took a longer operation time than that with spleen preservation. This difference was only significant in LDP group. In both RDP and LDP groups, splenectomy was associated with increased blood loss, as compared with spleen preservation. No significant differences were observed in surgical morbidity between RDP and LDP. The hospital cost in RDP was almost double that of LDP, with a median of 13,404 versus 7765 USD. Conclusion LDP is comparable to RDP in regard to surgical outcomes. LDP with spleen preservation is highly recommended whenever possible and feasible for benign or low malignant lesions in terms of lower costs and less blood loss.

Abstract
BACKGROUND While pancreatectomy with portomesenteric venous resection and reconstruction is commonly performed for locally advanced pancreatic adenocarcinoma, little is known regarding outcomes for pancreatic neuroendocrine neoplasms (panNENs). METHODS Patients who underwent non-parenchyma-sparing pancreatectomy for panNENs at Mayo Clinic from 2000 to 2020 were retrospectively reviewed. Propensity score matching was performed and patient characteristics and outcomes compared. RESULTS Of 867 eligible patients, 41 (4.7%) required vascular resection, including 38 patients who underwent portomesenteric venous resection only. Of these, 23 underwent pancreaticoduodenectomy or total pancreatectomy and 15 distal pancreatectomy. Patients who required portomesenteric venous resection had larger tumors, higher tumor grade, and higher disease stage. After propensity score matching to patients undergoing standard resection, the portomesenteric venous resection group had longer operative times, greater blood loss, and higher transfusion rates. While portomesenteric venous thrombosis was more common after venous resection, major complication rates and perioperative mortality were similar between the two groups, as were 5-year overall and progression-free survival. CONCLUSION For patients with locally advanced panNENs, pancreatectomy with portomesenteric venous resection and reconstruction can be performed in selected patients at high-volume centers with acceptable perioperative morbidity and short- and long-term survival.

[PMID: 35565442 PMCID: PMC9103421 DOI: 10.3390/cancers14092312] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Revised: 05/03/2022] [Accepted: 05/04/2022] [Indexed: 11/22/2022] Open
Abstract
Simple Summary Pancreatic neuroendocrine tumors (pNETs) are a heterogenous group of rare epithelial neoplasms. For most patients, surgery remains the only treatment modality to cure pNETs, and is recommended for patients with surgically resectable disease. Many of these tumors are non-functional tumors and do not produce clinical symptoms, so patients may present with locally advanced tumors, which invade surrounding organs or neighboring blood vessels. The presence of vascular involvement had previously been considered a contraindication to surgery, but, in recent years, at centers with considerable experience, aggressive surgery to remove pNETs with vascular reconstruction has been performed safely and with good long-term survival. In this review, we will discuss the considerations for resectability, review novel surgical approaches, and present the available evidence on the immediate and long-term postoperative outcomes. Abstract Complete surgical resection of pancreatic neuroendocrine tumors (pNETs) has been suggested as the only potentially curative treatment. A proportion of these tumors will present late during disease progression, and invade or encase surrounding vasculature; therefore, surgical treatment of locally advanced disease remains controversial. The role of surgery with vascular reconstruction in pNETs is not well defined, and there is considerable variability in the use of aggressive surgery for these tumors. Accurate preoperative assessment is critical to evaluate individual considerations, such as anatomical variants, areas and lengths of vessel involvement, proximal and distal targets, and collateralization secondary to the degree of occlusion. Surgical approaches to address pNETs with venous involvement may include thrombectomy, traditional vein reconstruction, a reconstruction-first approach, or mesocaval shunting. Although the amount of literature on pNETs with vascular reconstruction is limited to case reports and small institutional series, the last two decades of studies have demonstrated that aggressive resection of these tumors can be performed safely and with acceptable long-term survival.

Abstract
PURPOSE This study aimed to investigate the diagnostic performance of [68Ga]Ga-FAPI PET/CT for primary and metastatic pancreatic carcinoma lesions and compare the results with those of [18F]-fluorodeoxyglucose ([18F]FDG) PET/CT. METHODS Patients with suspected or diagnosed pancreatic malignancy, who underwent contemporaneous [18F]FDG and [68Ga]Ga-FAPI PET/CT between June 2020 and January 2021, were retrospectively analyzed. Routine contrast-enhanced CT (CE-CT) is performed in all patients as standardized care. Findings were confirmed by histopathology or radiographic follow-up. We compared radiotracer uptake, diagnostic performance, and TNM (tumor-node-metastasis) classifications. RESULTS We evaluated 36 participants (25/36 men; median age, 60 years), including 26 patients with pancreatic malignancies and ten patients with pancreatic benign lesions. [68Ga]Ga-FAPI PET/CT showed higher radiotracer uptake and higher sensitivity than [18F]FDG PET/CT in evaluating primary tumors (SUVmax, 21.4 vs. 4.8; sensitivity, 100% vs. 73.1%), involved lymph nodes (SUVmax, 8.6 vs. 2.7; sensitivity, 81.8% vs. 59.1%), and metastases (SUVmax, 7.9 vs. 3.5; sensitivity, 91.5% vs. 44.0%); Compared with [18F]FDG, [68Ga]Ga-FAPI PET/CT upstaged six patients' TNM staging (6/23, 26.1%) and changed two patients' clinical management (2/23, 8.7%). Compared with CE-CT, [68Ga]Ga-FAPI PET/CT upgraded TNM staging in five patients (5/23, 21.7%) and changed the therapeutic regimen in only one patient (1/23, 4.3%). Intense [68Ga]Ga-FAPI uptake was observed throughout the pancreas in 12/26 pancreatic malignancies; dual-time point [68Ga]Ga-FAPI PET/CT may differentiate pancreatitis from malignancy. CONCLUSIONS Compared with [18F]FDG PET/CT, [68Ga]Ga-FAPI PET/CT shows higher sensitivity in detecting primary pancreatic tumors, involved lymph nodes, and metastases and is superior in terms of TNM staging. Prospective trials with larger patient population are needed to evaluate whether [68Ga]Ga-FAPI PET/CT could elicit treatment modification in pancreatic cancer when compared with standard of care imaging.

Abstract
ABSTRACT Locally advanced and borderline resectable pancreatic cancers are being increasingly recognized as a result of significant improvements in imaging modalities. The main tools used in diagnosis of these tumors include endoscopic ultrasound, computed tomography, magnetic resonance imaging, and diagnostic laparoscopy. The definition of what constitutes a locally advanced or borderline resectable tumor is still controversial to this day. Borderline resectable tumors have been treated with neoadjuvant therapy approaches that aim at reducing tumor size, thus improving the chances of an R0 resection. Both chemotherapy and radiotherapy (solo or in combination) have been used in this setting. The main chemotherapy agents that have shown to increase resectability and survival are FOLFORINOX (a combination of folinic acid, fluorouracil, irinotecan, and oxaliplatin) and gemcitabine-nab-paclitaxel. Surgery on these tumors remains a significantly challenging task for pancreatic surgeons. More studies are needed to determine the best agents to be used in the neoadjuvant and adjuvant settings, biologic markers for prognostic and operative predictions, and validation of previously published retrospective results.

Abstract
BACKGROUND Though nowadays a palliative pancreaticoduodenectomy (PD) can be performed safely with relatively low mortality and acceptable morbidity rates in experienced centers, there have been no studies on the routine use of a palliative PD or on the advantages of performing surgical resection as a debulking procedure. Furthermore, the impact of resection margins on survival outcomes has been a matter of controversy. Therefore, this study aimed to clarify the role of robotic PD (RPD) in pancreatic and periampullary adenocarcinomas with positive resection margins. METHODS Patients undergoing RPDs and open PDs (OPDs) were included in this study. Based on the resection margins, the patients were divided into the R0, R1, and R2 PD groups. Surgical risks and survival outcomes were analyzed. RESULTS There were 348 PDs, including 29 (8.3%) palliative and 319 (91.7%) curative. Primary tumor origin, tumor sizes, perineural invasions, and abnormal serum carcinoembryonic antigen (CEA) levels were factors leading to palliative resection. The multivariate analysis showed that only pancreatic head adenocarcinomas and abnormal serum CEA levels (>5 ng/mL) were independent predictors. The surgical risks between curative and palliative PD were similar. There were no significant differences in the surgical risks and other surgical parameters between palliative RPDs and OPDs. For curative resection, RPDs resulted in less blood loss, greater harvested lymph nodes yield, less postoperative complications, less delayed gastric emptying, and shorter hospital stays than OPDs. The survival outcome was significantly better following R0 resection in overall periampullary adenocarcinomas, whereas a significant survival difference was shown only between the R0 and R2 resections for pancreatic head adenocarcinomas. CONCLUSION Compared with R0 PDs, palliative R1 PDs could benefit patients with pancreatic head adenocarcinomas when considering survival outcomes without increasing surgical risks. RPD can be considered for curative purposes and as an alternative for palliative management.

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
The annual incidence of pancreatic cancer is nearly 50,000 patients. The 5-year overall survival is only 9%, and there remains a great need for better therapy. A subset of these patients presents with locally advanced disease. Multidisciplinary therapy has evolved to include some combination of systemic chemotherapy, locoregional radiation, and surgery in select patients with excellent biology. This review will address the thoughtful evidence-based and individualized approach to these patients.

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.

Propensity score-matched comparison of the oncological feasibility and survival outcomes for pancreatic adenocarcinoma with robotic and open pancreatoduodenectomy. Surg Endosc 2021; 36:1507-1514.

Abstract
BACKGROUND This study is to clarify the feasibility of and justification for robotic pancreaticoduodenectomy (RPD) in patients with pancreatic adenocarcinoma. METHODS A 1-to-1 propensity score-matched comparison of RPD and open pancreaticoduodenectomy (OPD) was performed based on six covariates commonly used to predict the survival outcome for pancreatic adenocarcinoma. RESULTS A total of 130 patients were enrolled, with 65 in each study group after propensity score matching. The median operating time was longer for RPD (8.3 h vs. 7.0 h, P = 0.002). However, RPD was associated with less blood loss, lower overall surgical complication rate, and lower incidence of delayed gastric emptying. The resection radicality was oncologically similar between these two groups, but the median lymph node yield was higher for RPD (18 vs. 16, P = 0.038). Before propensity score matching, the 5-year survival was better in RPD (27.0% vs. 17.6%, P = 0.006). After matching, there was still a trend towards improved overall survival in the RPD group; however, the difference in 5-year survival between RPD and OPD was not significant (24.5% vs. 19.7%, P = 0.088). CONCLUSION RPD is not only technically feasible with no increase in surgical risk but also oncologically justifiable without compromising survival outcome. However, unlike randomized control trials, the limitations in this propensity score-matched analysis only accounted for 6 observed covariates commonly used to predict the survival outcome in patients with pancreatic adenocarcinoma, and confounders not included in this study could also affect our results.

Intention to treat outcomes among patients with pancreatic cancer treated using International Study Group on Pancreatic Surgery recommended pathways for resectable and borderline resectable disease. ANZ J Surg 2021; 91:1549-1557. [PMID: 33576568 DOI: 10.1111/ans.16643] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2020] [Revised: 01/21/2021] [Accepted: 01/22/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND The International Study Group on Pancreatic Surgery recommends upfront surgery for resectable pancreatic cancer or borderline resectable-venous (BR-V) disease and neoadjuvant therapy (NAT) among those with arterial involvement (BR-A or locally advanced, LA). Though neoadjuvant therapy (NAT) is a promising strategy, outcomes are rarely reported on intention-to-treat (ITT) basis. This study presents ITT outcomes where pathways to surgery were in line with International Study Group on Pancreatic Surgery guidelines. METHODS Patients recommended for potentially curative treatment with PDAC between 2012 and 2017 (n = 345) were classified as resectable, BR-A/BR-V or LA, according to NCCN criteria. The primary outcome was overall survival. Secondary outcomes were resection rates, positive margins and toxicity among patients receiving NAT. RESULTS At surgery, the resection rates were 78% (172/221), 65% (35/54) and 54% (21/39) for those with resectable, BR-V and BR-A/LA disease, respectively (P < 0.0001). The median survival of those resected in the BR-A/LA cohort was 31 months. However, on an ITT basis, there was no significant difference in survival between resectable, BR-V and BR-A/LA disease (median: 19 versus 15 versus 19 months; P = 0.585). On review, some 31 (44%) patients of the BR-A/LA cohort either did not receive or did not complete NAT. CONCLUSION To realize benefits of NAT, more patients need to complete NAT and to undergo resection. Upfront resection for BR-V disease is associated with equivalent outcomes to upfront surgery for resectable disease or NAT for BR-A/LA disease. Strategies to increase the proportion of patients who complete NAT and undergo resection are needed.

Abstract
Pancreatic cancer (PC) is a highly malignant tumor of the digestive tract, with a very poor prognosis and a 5-year survival rate of less than 8%. Most patients with PC have lost the chance of surgery at diagnosis because of the early invasion of important peripheral blood vessels, although R0 resection is the most important standard of radical surgery for PC. In recent years, the clinical application of pancreatectomy combined with portal vein/superior mesenteric vein resection has significantly improved the survival of patients with locally advanced PC. Therefore, many scholars are investigating whether pancreatectomy combined with arterial resection can benefit patients with locally advanced PC. Here, we review the recent progress regarding the treatment of PC using pancreatectomy combined with artery resection. Artery resection is not an absolute taboo for radical surgery in PC, and in selected patients with locally advanced PC, radical R0 resection and joint artery resection could achieve a relatively good clinical effect.

Abstract
Background Venous reconstruction has been recently demonstrated to be safe for tumours with invasion into portal vein and/or superior mesenteric vein. This study aims to compare the patency between various venous reconstructions. Methods This is retrospective study of 76 patients who underwent pancreaticoduodenectomy or total pancreatectomy with venous reconstruction from 2006 to 2018. Patient demographics, tumour histopathology, morbidity, mortality and patency were studied. Kaplan-Meier estimates were performed for primary venous patency. Results Sixty-two patients underwent pancreaticoduodenectomy and 14 underwent total pancreatectomy. Forty-seven, 19 and 10 patients underwent primary repair, end-to-end anastomosis and interposition graft respectively. Major morbidity (Clavien-Dindo >grade 2) and 30-day mortality were 14/76(18.4%) and 1/76(1.3%) respectively. There were 12(15.8%) venous occlusion including 4(5.3%) acute occlusions. Overall 6-month, 1-year and 2-year primary patency was 89.1%, 92.5% and 92.3% respectively. 1-year primary patency of primary repair was superior to end-to-end anastomosis and interposition graft (primary repair 100%, end-to-end anastomosis 81.8%, interposition graft 66.7%, p = 0.045). Pairwise comparison also demonstrated superior 1-year patency of primary repair (adjusted p = 0.037). There was no significant difference between the cumulative venous patency for each venous reconstruction method: primary repair 84±6%, end-to-end anastomosis 75±11% and interposition graft 76±15% (p = 0.561). Conclusion 1-year primary venous patency of primary repair is superior to end-to-end anastomosis and interposition graft.

Abstract
The question of when and how to drain a malignant biliary obstruction (MBO), both intrinsic or extrinsic, remains a controversial point among endoscopists. An important factor that influences the decision to drain an MBO or not is if the patient is a surgical candidate or not and, in the former case, if the patients must undergo neoadiuvant chemotherapy or not. Other questions arising during biliary drainage in MBO patients is which type of stent should be chosen, plastic or metal, and if endoscopic biliary sphincterotomy must be performed or not when a stent is placed. The present review attempts to answer these questions and summarizes the optimal approach toward patients with MBO based on the available evidence.

Abstract
OBJECTIVES The goal of this study was to compare outcomes of patients with borderline and resectable pancreatic cancer treated with neoadjuvant stereotactic body radiation therapy (SBRT) versus fractionated chemoradiation. METHODS Patients with borderline or resectable pancreatic cancer treated with neoadjuvant intent between November 2011 and December 2017 were reviewed. The SBRT volume/dose was 33 Gy in 5 fractions to gross tumor plus abutting vessel with or without 25 Gy in 5 fractions to pancreatic head/body and celiac/superior mesenteric artery. Fractionated chemoradiation volume/dose was 50.4 Gy in 28 fractions to gross tumor, superior mesenteric/celiac arteries, and enlarged lymph nodes with concurrent bolus 5-FU, leucovorin, oxaliplatin, irinotecan or gemcitabine/nab-paclitaxel. Failure patterns, local recurrence-free survival (LRFS), progression-free survival (PFS), and overall survival were assessed. RESULTS Forty-three patients were reviewed (18 SBRTs and 25 fractionated). Among patients who underwent resection, patients treated with fractionated chemoradiation had improved LRFS (12-month LRFS, 86% vs 62%, P = 0.003) and PFS (median PFS, 23 months vs 11 months, P = 0.006) compared with SBRT. There was no difference in overall survival. CONCLUSIONS Stereotactic body radiation therapy may result in inferior LRFS and PFS compared with fractionated chemoradiation, likely because of under coverage of high-risk vascular targets.

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
OBJECTIVES This study aimed to analyze the risk factors for poor survival of the patients with anatomically resectable pancreatic ductal adenocarcinoma (PDAC), focusing on detailed computed tomography (CT) findings of tumor extent to the peripancreatic tissue. METHODS The study included 192 patients who underwent upfront pancreaticoduodenectomy for anatomically resectable PDAC. Preoperative CT images were rereviewed by an experienced radiologist for the pattern of tumor extension to the surrounding tissue: biliary, duodenal, serosal, retroperitoneal, portal venous, arterial, extrapancreatic nerve plexus, and other-organ invasion. Imaging findings and other clinical data that could be obtained before surgery were evaluated for their association with a shorter disease-specific survival (DSS) and recurrence-free survival (RFS). RESULTS Of the 192 anatomically resectable PDAC patients, extrapancreatic nerve plexus invasion was observed on CT in 38 patients (20%), and this finding was independently associated with a shorter DSS (hazard ratio, 2.258; P < 0.001) and RFS (hazard ratio, 2.665; P < 0.001). The median survival of patients with and without extrapancreatic nerve plexus invasion on CT was 19.7 versus 38.5 months (P < 0.001). CONCLUSIONS Extrapancreatic nerve plexus invasion was shown as an only CT finding associated with a shorter DSS and RFS after upfront surgery for the patients with anatomically resectable PDAC.

Abstract
BACKGROUND Vascular reconstruction during pancreaticoduodenectomy is increasingly utilized to improve pancreatic cancer resectability. However, few multi-institutional studies have evaluated the morbidity and mortality of arterial and venous reconstruction during this procedure. METHODS A retrospective analysis was performed utilizing the targeted pancreas module of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) for pancreaticoduodenectomy from 2014 to 2015. Demographics, comorbidities, and 30-day outcomes for patients who underwent venous or arterial reconstruction and both were compared to no reconstruction. RESULTS A total of 3002 patients were included in our study: 384 with venous reconstruction, 52 with arterial, 81 with both, and 2566 without. Compared to patients without reconstruction, those who underwent venous reconstruction had more congestive heart failure (1.8% vs 0.2%, P < 0.01), those with arterial reconstruction had higher rates of pulmonary disease (11.5% vs. 4.5%, P = 0.02), and neoadjuvant chemotherapy was more common in both venous (34% vs 12%, P < 0.01) and arterial reconstruction (21% vs 12%, P = 0.04). In multivariable analysis, there was no increase in morbidity or mortality following venous reconstruction. However, arterial reconstruction was associated with increased 30-day mortality with an odds ratio (OR): 6.7, 95%; confidence interval (CI): 1.8-25. Morbidity was increased as represented with return to the operating room (OR: 4.5, 95%; CI: 1.5-15), pancreatic fistula (OR: 4.4, 95%; CI: 1.7-11), and reintubation (OR: 3.9, 95%; CI: 1.1-14). CONCLUSIONS Venous reconstruction during pancreaticoduodenectomy does not increase perioperative morbidity or mortality and should be considered for patients previously considered to be unresectable or those where R0 resection would otherwise not be possible due to venous involvement. Careful consideration should be made prior to arterial reconstruction given the significant increase in perioperative complications and death within 30 days.

Abstract
Multidetector computed tomography (MDCT) is a widely used cross-sectional imaging modality for initial evaluation of patients with suspected pancreatic ductal adenocarcinoma (PDAC). However, diagnosis of PDAC can be challenging due to numerous pitfalls associated with image acquisition and interpretation, including technical factors, imaging features, and cognitive errors. Accurate diagnosis requires familiarity with these pitfalls, as these can be minimized using systematic strategies. Suboptimal acquisition protocols and other technical errors such as motion artifacts and incomplete anatomical coverage increase the risk of misdiagnosis. Interpretation of images can be challenging due to intrinsic tumor features (including small and isoenhancing masses, exophytic masses, subtle pancreatic duct irregularities, and diffuse tumor infiltration), presence of coexisting pathology (including chronic pancreatitis and intraductal papillary mucinous neoplasm), mimickers of PDAC (including focal fatty infiltration and focal pancreatitis), distracting findings, and satisfaction of search. Awareness of pitfalls associated with the diagnosis of PDAC along with the strategies to avoid them will help radiologists to minimize technical and interpretation errors. Cognizance and mitigation of these errors can lead to earlier PDAC diagnosis and ultimately improve patient prognosis.

Abstract
INTRODUCTION Currently, R1 resection is defined by the presence of tumor cells within <1mm of the resection margin. The main aim of this study was to analyze the impact of positive margins (R1) on survival outcomes in pancreatic cancer. METHODS We performed a retrospective analysis with multivariate regression analysis of a prospective database from 2008-2017, which included resection margin status, expanded resection margin (R1<1mm), vascular resection, lymphatic involvement, surgical complications, tumor differentiation grade and adjuvant treatment. RESULTS A total of 80 patients were analyzed: 42 (52%) R1; 38 (48%) R0. No differences were found in the composition of the two groups except for the vascular resection, which was more frequent in the R1 group: 12 (21%) vs 2 (3%). Overall survival in the R0 group was 19 months vs 24 months in the R1 group (p=0.13). Wide R1 (R1<1mm) had an overall survival of 21 months versus 31 months in wide R0 (p=0.55). In the multivariate analysis, only lymph node involvement (p=0.02, HR=2.88), tumor differentiation (p=0.02, HR=3.2) and adjuvant therapy (p<0.01; HR=0.21) were found to be factors related to survival. CONCLUSIONS R1 resection is not an independent risk factor. Lymph node involvement, differentiation grade and adjuvant treatment are prognostic factors. The benefit of expanding the resection margins should be demonstrated. More studies are needed to assess the impact of the resection margin.

Abstract
Pancreatic surgery with en bloc venous resection and reconstruction is becoming increasingly common in the current era of expanding neoadjuvant oncologic therapies and advanced surgical techniques for patients with more anatomically complex tumors. However, patients who have alterations in their venous outflow are at increased risk for postoperative portomesenteric venous stenosis and/or thrombosis. Cross-sectional imaging for postoperative surveillance, including multiphase CT or MRI, is critical for recognizing portomesenteric venous complications and thus implementing early intervention and preventing complications related to portomesenteric venous hypertension. Hypertension-related complications include ascites, variceal or gastrointestinal bleeding, postprandial abdominal pain, intestinal edema, protein-losing enteropathy, malabsorptive diarrhea, and splenomegaly. Percutaneous transhepatic, transsplenic, and transjugular portomesenteric interventions, including venoplasty, stent placement, and thrombectomy or thrombolysis, are safe and effective options for restoring patency to the portomesenteric venous system. Preintervention CT or MRI and diagnostic catheter venography are important for procedural planning, while postintervention CT or MRI surveillance is critical for detecting recurrent stenosis or thrombosis, or de novo portomesenteric venous disease.

Abstract
PURPOSE To evaluate technical success, efficacy and safety of portomesenteric venous (PMV) intervention for PMV stenosis or occlusion following nontransplant hepatobiliary or pancreatic (HPB) surgery. MATERIALS AND METHODS A retrospective review identified 42 patients (mean age 60 y) with PMV stenosis (n = 33; 79%) or occlusion (n = 9; 21%) who underwent attempted PMV intervention following HPB surgery between June 1, 2011, and April 1, 2018. Main outcomes were technical success, primary patency rates, and complications. Technical success was compared by venous pathology and primary PMV patency based on anticoagulation status after the procedure using Fisher exact test. Rates of primary patency by stent group were estimated using Kaplan-Meier method. RESULTS Technical success was 91% (n = 38/42) and significantly higher in patients with stenosis (n = 33/33; 100%) vs occlusion (n = 5/9; 56%) (P = .001). Primary presenting symptom resolved in 28 (87%) patients, including 6 (100%) patients with gastrointestinal bleeding. At mean imaging follow-up of 8.6 months ± 8.8, primary stent patency was 76%. There was no significant difference in primary stent patency based on anticoagulation status after the procedure (P = .48). There were 2 (4.8%) periprocedural complications. CONCLUSIONS Portomesenteric venoplasty and stent placement following nontransplant HPB surgery is safe with a high rate of technical success if performed before chronic occlusion.

Pattern of Marginal Local Failure in a Phase II Trial of Neoadjuvant Chemotherapy and Stereotactic Body Radiation Therapy for Resectable and Borderline Resectable Pancreas Cancer. Am J Clin Oncol 2019; 42:247-252.

Abstract
OBJECTIVES The main objectives of this study were to prospectively evaluate the safety and efficacy of stereotactic body radiation therapy (SBRT) in the neoadjuvant setting for resectable or borderline resectable pancreatic cancer. MATERIALS AND METHODS Eighteen patients were enrolled from November 2014 to June 2017. Following 3 cycles of chemotherapy, SBRT was delivered to the tumor and abutting vessel and a 3 mm planning target volume (PTV) margin to 33 Gy (6.6 Gy×5) with an optional elective PTV to 25 Gy (5 Gy×5) customized to the nodal space and mesenteric vessels. The primary endpoint is ≥grade 3 acute and late gastrointestinal toxicity. RESULTS Fifteen patients had borderline resectable tumors due to arterial abutment (n=7) or superior mesenteric vein encasement (n=8); 3 patients had resectable tumors. There were no ≥grade 3 acute or late gastrointestinal events. Following SBRT, surgery was performed in 12 patients (67%) with 11 (92%) R0 resections. The median overall survival and progression-free survival was 21 months (95% CI: 18-29) and 11 months (95% CI: 8.4-16). Progression occurred in 83% (10/12) of resected patients (distant [n=4, 40%], local-only [n=4, 40%], and local and distant [n=2, 20%]). The cumulative incidence of local failure (LF) at 12 months from resection was 50% (95% CI: 20-80). All LF were outside to the PTV33. CONCLUSIONS Neoadjuvant SBRT was well tolerated, however LFs were predominantly observed outside the PTV33 volume that would have been covered with conventional RT volumes. The durability of local control after SBRT in the neoadjuvant setting merits examination relative to chemoradiation before incorporation into routine practice.

Abstract
BACKGROUND AND OBJECTIVES Conclusive evidence in favor of neoadjuvant therapy for those with non-metastatic pancreatic ductal adenocarcinoma (PDAC) is still lacking. The objective of this study was to evaluate the survival benefit of neoadjuvant therapy vs upfront surgery for patients with non-metastatic PDAC. METHODS The study involved 565 patients undergoing neoadjuvant therapy or upfront surgery as the primary treatment for PDAC. Propensity score matching was performed between the neoadjuvant therapy group (NAT group) and the upfront surgery group (UFS group) using 20 clinical variables at diagnosis. Overall survival and surgical pathology were compared between the two treatment groups on an intent-to-treat basis. RESULTS In the matched cohort, the NAT group (n = 91) had a longer median overall survival than the UFS group (n = 91) (23.1 months vs 18.5 months, P = .043). The rate of patients undergoing surgical resection was lower in the NAT group (58% vs 80%, P = .001). Regarding surgical pathology, the NAT group had smaller tumor size (2.8 cm vs 4.0 cm, P = .001), lower incidence of positive surgical margins (8% vs 30%, P < .002), and less lymph node metastasis (45% vs 78%, P < .001). CONCLUSIONS The strategy of neoadjuvant therapy before surgical resection appears to offer pathologic effect and survival benefit for the patients presenting with non-metastatic PDAC.

Abstract
Background The outcomes in patients with pancreatic or ampulla tumors remain unsatisfactory, especially with invasion into the hepatic artery (HA) or the superior mesenteric artery (SMA). In this setting, pancreatectomy combined with arterial resection and reconstruction may offer the possibility of an en-block resection with negative margins and acceptable morbidity and mortality. Methods A six year retrospective review of pancreatectomies performed at our institution, included 21 patients that underwent a pancreatectomy combined with arterial resection and reconstruction. Arterial reconstruction was performed under an operating microscope. The types of arterial reconstruction included direct anastomosis, arterial transposition, and arterial bypass with a vascular graft. Results The surgical procedures consisted of 19 pancreaticoduodenectomies and 2 total pancreatectomies. The tumors were located at the pancreatic head (n = 10), whole pancreas (n = 2), distal common bile duct (n = 5), ampulla (n = 2) and retroperitoneum with pancreatic head involvement (n = 2). All operations achieved R0 resection successfully, with no intraoperative complication. Eighteen patients recovered without complications while three patients died from intra-abdominal hemorrhage due to a pancreatic fistula, though notably the bleeding was not at the arterial anastomosis site. All reconstructed arteries showed adequate patency at follow-up. The median postoperative survival was 11.6 months in all the 11 patients with pancreatic adenocarcinoma. Conclusion Pancreatectomy combined with arterial resection and reconstruction is a feasible treatment option. The microsurgical technique is critically important to achieving a successful and patent arterial anastomosis.

Abstract
BACKGROUND It is difficult to successfully deliver multimodality therapy to patients with operable pancreatic cancer. Data on the natural history of such efforts are necessary for physicians to guide shared decision-making with patients and families. We report the survival of consecutive patients with borderline resectable pancreatic cancer who received neoadjuvant therapy before surgery. METHODS Data regarding demographics, neoadjuvant therapy, surgery, pathology, and survival duration were abstracted on consecutive patients with borderline resectable pancreatic cancer diagnosed between 2009 and 2017 and not treated on available clinical trials. Borderline resectable pancreatic cancer was defined based on ≥1 of the following: local tumor anatomy, pretreatment serum carbohydrate antigen 19-9 >2,000 U/mL, and the presence of radiographic lesions indeterminate for metastases. RESULTS Neoadjuvant therapy was delivered to 185 patients with borderline resectable pancreatic cancer who were not enrolled in competing clinical trials; 13 (7%) patients received chemoradiation, 12 (7%) received chemotherapy, and 160 (86%) received both. Of the 185 patients, 115 (62%) completed all intended neoadjuvant therapy and surgery; 81 (70%) of 115 underwent pancreaticoduodenectomy; and vascular reconstruction was performed in 51 (44%). A margin negative resection was achieved in 111 (97%) of 115 patients, and 83 (72%) were node negative. Median overall survival for all 185 patients was 20 months; 31 months for the 115 patients who completed all neoadjuvant therapy and surgery as compared to 13 months for the 70 patients who were not resected (P < .0001). CONCLUSION After neoadjuvant therapy, surgical resection was performed in 62% of patients with borderline resectable pancreatic cancer. Those who normalized preoperative serum carbohydrate antigen 19-9 and had node negative pathology achieved the longest survival. To further improve median survival for all patients, we are incorporating adaptive approaches to neoadjuvant therapy sequencing based on objective assessments of response.

Abstract
BACKGROUND Few studies have investigated the outcome of pancreatectomy associated with artery resection (PAR). METHODS Retrospective analysis of a cohort of operated borderline or locally advanced pancreatic cancer patients with surgically confirmed arterial involvement. Short and long-term outcome were analyzed and compared in patients who underwent PAR (Group 1) and palliative surgery (Group 2). RESULTS Of 73 patients who underwent surgical exploration with intent of resection, 34 underwent PAR (±venous resection) (Group 1) and 39 underwent palliation (Group 2). 23 patients (67.7%) in Group 1 underwent combined artery-vein resection (AVR). Operation time was longer and blood loss higher in group 1 compared to group 2. There were no differences in post-operative mortality (2.9% vs 2.6%, p = 0.9) and post-operative surgical complications (38.2% vs 25.6%, p = 0.2). The 1, 3 and 5 years survival in Group 1 was superior to Group 2 (63.7%, 23.4% and Q3 23.4% vs 41.7%, 3.2% and 0, p = 0.003). CONCLUSION PAR seems to be safe and feasible in well selected patients and associated with an advantage of survival compared to palliation, in patients affected by locally advanced pancreatic cancer.

Abstract
BACKGROUND The MDACC group recommends to extend the current borderline classification for pancreatic cancer into three groups: type A patients with resectable/borderline tumor anatomy, type B with resectable/borderline resectable tumor anatomy and clinical findings suspicious for extrapancreatic disease and type C with borderline resectable and marginal performance status/severe pre-existing comorbidity profile or age>80. This study intents to evaluate the proposed borderline classification system in a multicenter patient cohort without neoadjuvant treatment. METHODS Evaluation was based on a multicenter database of pancreatic cancer patients undergoing surgery from 2005 to 2016 (n = 1020). Complications were classified based on the Clavien-Dindo classification. χ2-test, Kaplan-Meier estimator and Cox regression hazard model were used for statistical analysis. RESULTS Most patients (55.1%) were assigned as type A patients, followed by type C (35.8%) and type B patients (9.1%). Neither the complication rate, nor the mortality rate revealed a correlation to any subgroup. Type B patients had a significant worse progression free (p < 0.001) and overall survival (p = 0.005). Type B classification was identified as an independent prognostic marker for progression free survival (p = 0.005, HR 1.47). CONCLUSION The evaluation of the proposed classification in a cohort without neoadjuvant treatment did not justify an additional medical borderline subgroup. A new subgroup based on prognostic borderline patients might be the main target group for neoadjuvant protocols in future.

Intraoperative radiotherapy with the Intrabeam ® device for the treatment of resectable pancreatic adenocarcinoma. Cir Esp 2018; 96:482-487. [PMID: 30297032 DOI: 10.1016/j.ciresp.2018.04.014] [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: 09/15/2017] [Revised: 02/25/2018] [Accepted: 04/24/2018] [Indexed: 02/07/2023]
Abstract
INTRODUCTION The application of intraoperative radiation therapy to the tumor bed after resection of pancreatic cancer has been shown to be beneficial in the local control of the disease. The objective of this study was to evaluate the preliminary outcomes after the application of a single intraoperative dose to the tumor bed with a new intraoperative radiotherapy device (Intrabeam®) in terms of viability, safety and short-term results. METHODS We studied 5 patients who underwent pancreaticoduodenectomy for resectable pancreatic cancer in which a radiotherapy boost (5Gy) was intraoperatively applied to the tumoral bed using the portable Intrabeam® device, a low-energy point-source X-ray. Postoperative complications, hospital stay and mortality, recurrences and short-term survival were analyzed. RESULTS Mean patient age was 68 years. All patients had a T3-stage tumor and one of them N1. In 3 patients, R0 resection was performed, while R1 resection was conducted in 2. Perioperative mortality was 0%. The only complications included delayed gastric emptying and postoperative hemorrhage. There were no pancreatic fistulas. During follow-up (mean: 11.2 months), there was a relapse in the patient who had undergone R1 resection. CONCLUSIONS The application of radiotherapy with the Intrabeam® device in selected patients has not resulted in increased perioperative morbidity or mortality; therefore, this is a safe procedure for the treatment of resectable cancer.

Does mesenteric venous imaging assessment accurately predict pathologic invasion in localized pancreatic ductal adenocarcinoma? HPB (Oxford) 2018; 20:925-931. [PMID: 29753633 DOI: 10.1016/j.hpb.2018.03.014] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2017] [Revised: 02/28/2018] [Accepted: 03/31/2018] [Indexed: 12/12/2022]
Abstract
BACKGROUND Accurate prediction of mesenteric venous involvement in pancreatic ductal adenocarcinoma (PDAC) is necessary for adequate staging and treatment. METHODS A retrospective cohort study was conducted in PDAC patients at a single institution. All patients with resected PDAC and staging CT and EUS between 2003 and 2014 were included and sub-divided into "upfront resected" and "neoadjuvant chemotherapy (NAC)" groups. Independent imaging re-review was correlated to venous resection and venous invasion. Sensitivity, specificity, positive and negative predictive values were then calculated. RESULTS A total of 109 patients underwent analysis, 60 received upfront resection, and 49 NAC. Venous resection (30%) and vein invasion (13%) was less common in patients resected upfront than those who received NAC (53% and 16%, respectively). Both CT and EUS had poor sensitivity (14-44%) but high specificity (75-95%) for detecting venous resection and vein invasion in patients resected upfront, whereas sensitivity was high (84-100%) and specificity was low (27-44%) after NAC. CONCLUSIONS Preoperative CT and EUS in PDAC have similar efficacy but different predictive capacity in assessing mesenteric venous involvement depending on whether patients are resected upfront or received NAC. Both modalities appear to significantly overestimate true vascular involvement and should be interpreted in the appropriate clinical context.

[PMID: 30153902 DOI: 10.1016/j.pan.2018.07.001] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2018] [Revised: 06/28/2018] [Accepted: 07/03/2018] [Indexed: 12/11/2022]
Abstract
BACKGROUND Surgical resection remains the only curative option for pancreatic adenocarcinoma. Despite recent improvements in medical imaging, unresectability is still often discovered at the time of surgery. It is essential to identify unresectable patients preoperatively to avoid unnecessary surgery. High serum CA 19-9 levels have been suggested as a marker of unresectability but considered inaccurate in patients with hyperbilirubinemia. AIM OF THE STUDY To evaluate CA 19-9 serum levels as a predictor of unresectability of pancreatic adenocarcinomas with a special focus on jaundiced patients. METHODS All patients presenting with histologically-confirmed pancreatic adenocarcinoma and having serum CA 19-9 levels available prior to any treatment were included in this retrospective study. The relationship between serum concentrations of CA 19-9 and resectability was studied by regression analysis and theROC curves obtained. A cut-off value of CA 19-9 was calculated. In jaundiced patients, a CA 19-9 adjusted for bilirubinemia was also evaluated. RESULTS Of the 171 patients included, 49 (29%) were deemed resectable and 122 (71%) unresectable. Altogether, 93 patients (54%) had jaundice. The area under the ROC curve for CA 19-9 as a predictor of resectability was 0.886 (95%CI:[0.832-0.932]); in jaundiced patients it was 0.880 (95% CI [0.798-0.934]. A cut-off in CA 19-9 at 178 UI/mlyielded 85% sensitivity, 81% specificity and 91% positive predictive value for resectability. There was no correlation between the levels of bilirubin and CA 19-9 (r = 0.149). CONCLUSION Serum CA 19-9 is a good predictive marker of unresectability of pancreatic adenocarcinoma, even in jaundiced patients. CA 19-9 levels over 178 UI/ml strongly suggest unresectable disease.

J Am Coll Surg 2018; 227:255-269. [PMID: 29752997 DOI: 10.1016/j.jamcollsurg.2018.05.001] [Citation(s) in RCA: 78] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2018] [Revised: 04/04/2018] [Accepted: 05/03/2018] [Indexed: 12/14/2022]
Abstract
BACKGROUND Pancreatectomy with arterial resection (AR) is performed infrequently. As indications evolve, we evaluated indications, outcomes, and predictors of mortality, morbidity, and survival after AR. STUDY DESIGN We performed a single-institution review of elective pancreatectomies with AR (from July1990 to July 2017). Univariate and multivariate analyses were performed for predictors of outcomes and survival. RESULTS A total of 111 patients underwent pancreatectomy with AR including any hepatic (54%), any celiac (44%), any superior mesenteric (14%), or multiple ARs (14%), with revascularization in 55%. The majority of cases were planned (77%) and performed post-2010 (78%). Overall 90-day major morbidity (≥grade III) and mortality were 54% and 13%, respectively, due to post-pancreatectomy hemorrhage (PPH), postoperative pancreatic fistula (POPF), or ischemia in the majority of cases. There was a significant decrease in mortality post-2010 (9% vs 29%, p = 0.02), and this was protective on multivariate analysis (odds ratio [OR] 0.1, p = 0.004); PPH increased mortality (OR 6.1, p < 0.001). Post-pancreatectomy hemorrhage was associated with major morbidity (OR 5.1, p = 0.005), reoperation (OR = 23.0, p = 0.004), ICU (OR 5.5, p < 0.001), and readmission (OR 2.6, p = 0.004). Other morbidity predictors were AR with graft (OR 4.0, p = 0.031) and POPF (OR 3.1, p = 0.003). Median survival was 28.5 months and improved for ductal adenocarcinoma after neoadjuvant chemotherapy (p = 0.038). There were no differences in survival based on AR type. CONCLUSIONS Regardless of indication or type, pancreatectomy with AR is associated with risks greater than standard resections. Mortality has decreased in the modern era; however, morbidity remains high from hemorrhagic, fistula, or ischemia-related complications. Mitigation measures are needed if advanced resections are considered with increasing frequency given the potential oncologic benefit of AR in selected cases after modern chemotherapy.

Abstract
Pancreatic cancer has a high mortality rate due to late diagnosis and the tendency to invade surrounding tissues and metastasize at an early stage. A molecular imaging agent that enables both presurgery antigen-specific PET (immuno-PET) and intraoperative near-infrared fluorescence (NIRF) guidance might benefit diagnosis of pancreatic cancer, staging, and surgical resection, which remains the only curative treatment. Methods: We developed a dual-labeled probe based on A2 cys-diabody (A2cDb) targeting the cell-surface prostate stem cell antigen (PSCA), which is expressed in most pancreatic cancers. Maleimide-IRDye800CW was site-specifically conjugated to the C-terminal cys-tag (A2cDb-800) without impairing integrity or affinity (half-maximal binding, 4.3 nM). Direct radioiodination with 124I (124I-A2cDb-800) yielded a specific activity of 159 ± 48 MBq/mg with a radiochemical purity exceeding 99% and 65% ± 4.5% immunoreactivity (n = 3). In vivo specificity for PSCA-expressing tumor cells and biodistribution of the dual-modality tracer were evaluated in a prostate cancer xenograft model and compared with single-labeled 124I-A2cDb. Patient-derived pancreatic ductal adenocarcinoma xenografts (PDX-PDACs) were grown subcutaneously in NSG mice and screened for PSCA expression by immuno-PET. Small-animal PET/CT scans of PDX-PDAC-bearing mice were obtained using the dual-modality 124I-A2cDb-800 followed by postmortem NIRF imaging with the skin removed. Tumors and organs were analyzed ex vivo to compare the relative fluorescent signals without obstruction by other organs. Results: Specific uptake in PSCA-positive tumors and low nonspecific background activity resulted in high-contrast immuno-PET images. Concurrent with the PET studies, fluorescent signal was observed in the PSCA-positive tumors of mice injected with the dual-tracer 124I-A2cDb-800, with low background uptake or autofluorescence in the surrounding tissue. Ex vivo biodistribution confirmed comparable tumor uptake of both 124I-A2cDb-800 and 124I-A2cDb. Conclusion: Dual-modality imaging using the anti-PSCA cys-diabody resulted in high-contrast immuno-PET/NIRF images of PDX-PDACs, suggesting that this imaging agent might offer both noninvasive whole-body imaging to localize PSCA-positive pancreatic cancer and fluorescence image-guided identification of tumor margins during surgery.

Abstract
INTRODUCTION Borderline resectable pancreatic cancer (BRPC) can involve the portal vein, superior mesenteric vein, superior mesenteric artery, coeliac axis or hepatic artery, and has a high probability of positive surgical margins and poor prognosis after resection. Neoadjuvant chemoradiation is expected to provide substantial local control and prolong survival in patients with BRPC. METHODS AND ANALYSIS This open-label, multicentre, prospective phase II trial will assess S-1 with concurrent radiotherapy as preoperative treatment for BRPC. Participants will receive S-1 (40 mg/m2 twice daily) and concurrent radiotherapy (50.4 Gy in 28 fractions), with restaging and surgery after 3-8 weeks. Recruitment will be for a 36-month period with a minimum 24-month follow-up. The primary endpoint is the R0 resection rate for BRPC confirmed with central review. The secondary endpoints are overall survival, disease-free survival, response rate to neoadjuvant chemoradiation, pathological response rate, 2-year survival rate, surgical morbidity rate and acute and late toxicity rates. Objectives include quantifying the number of participants per year to evaluate whether randomised trials can be performed for this rare tumour. ETHICS AND DISSEMINATION This trial has been approved by the National Cancer Center Institutional Review Board. Written informed consent will be obtained from all participants. Serious adverse events will be reported to the safety desk of the trial, the Data and Safety Monitoring Board and trial sites. Trial results will be submitted for peer-reviewed publication.

Abstract
Historically, the clinical staging of pancreatic cancer has centered on the surgical management of the primary tumor, because few effective chemotherapeutic agents were available and long-term survival was only achieved in the context of surgical resection. Such a strategy of complete oncologic surgical care is reasonable when surgery is both the principal therapy and highly effective. However, complex surgery for pancreatic cancer-often performed in older patients after a lengthy period of induction therapy-can be associated with significant morbidity and mortality. The majority of patients with pancreatic cancer present either locally advanced or metastatic disease at the time of diagnosis. In this article, we will discuss the role of multimodality management of patients with borderline resectable and locally advanced pancreatic cancer. Considering that surgery has a modest impact on the natural history of pancreatic cancer in most patients, a neoadjuvant approach to treatment sequencing is favored for patients with borderline resectable pancreatic cancer, and this same rationale has been extended to select patients with locally advanced disease who demonstrate an exceptional response to induction therapy.

Abstract
BACKGROUND Laparoscopic resection as an alternative to open pancreatoduodenectomy may yield short-term benefits, but has not been investigated in a randomized trial. The aim of this study was to compare laparoscopic and open pancreatoduodenectomy for short-term outcomes in a randomized trial. METHODS Patients with periampullary cancers were randomized to either laparoscopic or open pancreatoduodenectomy. The outcomes evaluated were hospital stay (primary outcome), and blood loss, radicality of surgery, duration of operation and complication rate (secondary outcomes). RESULTS Of 268 patients, 64 who met the eligibility criteria were randomized, 32 to each group. The median duration of postoperative hospital stay was longer for open pancreaticoduodenectomy than for laparoscopy (13 (range 6-30) versus 7 (5-52) days respectively; P = 0·001). Duration of operation was longer in the laparoscopy group. Blood loss was significantly greater in the open group (mean(s.d.) 401(46) versus 250(22) ml; P < 0·001). Number of nodes retrieved and R0 rate were similar in the two groups. There was no difference between the open and laparoscopic groups in delayed gastric emptying (7 of 32 versus 5 of 32), pancreatic fistula (6 of 32 versus 5 of 32) or postpancreatectomy haemorrhage (4 of 32 versus 3 of 32). Overall complications (defined according to the Clavien-Dindo classification) were similar (10 of 32 versus 8 of 32). There was one death in each group. CONCLUSION Laparoscopy offered a shorter hospital stay than open pancreatoduodenectomy in this randomized trial. Registration number: NCT02081131( http://www.clinicaltrials.gov).
