Abstract
BACKGROUND AND OBJECTIVES This study aimed to evaluate the prognostic value of aberrant right hepatic artery (A-RHA) involvement in patients with pancreatic cancer (PC). METHODS This study enrolled 474 patients who underwent upfront pancreatectomy or neoadjuvant treatment for resectable (R) or borderline resectable (BR) PC from four institutions. The patients were divided into three groups: A-RHA involvement group (n = 12), patients who had sole A-RHA involvement without major arterial involvement; BR-A group (n = 104), patients who had major arterial involvement; R/BR-PV group (n = 358), others. RESULTS All patients in the A-RHA involvement group underwent margin-negative resection. The median overall survival of the entire cohort in the A-RHA involvement, R/BR-PV, and BR-A groups was 41.2, 33.5, and 25.2 months, respectively. Although survival in the R/BR-PV group was significantly more favorable than that in the BR-A group (p = 0.0003), no significant difference was observed between the A-RHA involvement group and the R/BR-PV (p = 0.7332) and BR-A (p = 0.1485) groups. CONCLUSIONS The prognosis of patients with PC and sole A-RHA involvement was comparable to that of patients with R/BR-PV.

Abstract
Background The artery involvement explains the majority of primary unresectability of non-metastatic pancreatic cancer patients and both arterial resection and artery-sparing dissection techniques are utilized in curative-intent pancreatectomies for artery-involving pancreatic cancer (ai-PC) patients. Methods This narrative review summarized the history of resectability evaluation for ai-PC and attempted to interpret its current pitfalls that led to the divergence of resectability prediction and surgical exploration, with a focus on the rationale and the surgical outcomes of the sub-adventitial divestment technique. Results The circumferential involvement of artery by tumor currently defined the resectability of ai-PC but insufficient to preclude laparotomy with curative intent. The reasons behind could be: 1. The radiographic involvement of tumor to arterial circumference was not necessarily resulted in histopathological artery wall invasion; 2. the developed surgical techniques facilitated radical resection, better perioperative safety as well as oncological benefit. The feasibility of periadventitial dissection, sub-adventitial divestment and other artery-sparing techniques for ai-PC depended on the tumor invasion depth to the artery, i.e., whether the external elastic lamina (EEL) was invaded demonstrating a hallmark plane for sub-adventitial dissections. These techniques were reported to be complicated with preferable surgical outcomes comparing to arterial resection combined pancreatectomies, while the arterial resection combined pancreatectomies were considered performed in patients with more advanced disease. Conclusions Adequate preoperative imaging modalities with which to evaluate the tumor invasion depth to the artery are to be developed. Survival benefits after these techniques remain to be proven, with more and higher-level clinical evidence needed. Key message The current resectability evaluation criteria, which were based on radiographic circumferential involvement of the artery by tumor, was insufficient to preclude curative-intent pancreatectomies for artery-involving pancreatic cancer patients. With oncological benefit to be further proven, periarterial dissection and arterial resection have different but overlapping indications, and predicting the tumor invasion depth in major arteries was critical for surgical planning.

Abstract
Pancreatic cancer has a dire prognosis and will represent the second leading cause of cancer death in the next 10 years. The multifactorial approach represents one of the main issues in controlling the extension of this neoplasm. In recent years, the characteristics of the tumor microenvironment, metastasis mechanisms and the relationship between immune system and neoplastic cells have been described, which has made it possible to understand the pathophysiology of pancreatic adenocarcinoma. Currently, there is a failure to provide an effective preventive method or early detection, so patients present with an advanced stage at the time of diagnosis. Despite numerous efforts, little progress has been made in clinical outcome and in improving survival in long term. Therefore, in the recent years, diverse diagnostic tests, treatments and possible approaches have been developed in the fields of radiotherapy, chemotherapy and surgery to find a combination of them that improves life expectancy in patients diagnosed with pancreatic cancer. At the moment, numerous clinical trials are being conducted to evaluate preventive diagnostic procedures such as serological markers or perfecting available imaging tests. On the other hand, implementation of immunotherapy is being studied in a neoplasm that has lagged in the application of this procedure since present possible treatments do not substantially improve quality of life. Therefore, the purpose of our study is to summarize the main progresses that have been made in the diagnosis, treatment and screening of this disease, explaining the limitations that have been observed and analyzing future prospects in the management of this illness.

Pre-Operative MDCT Staging Predicts Mesopancreatic Fat Infiltration-A Novel Marker for Neoadjuvant Treatment? Cancers (Basel) 2021; 13:cancers13174361. [PMID: 34503170 PMCID: PMC8430607 DOI: 10.3390/cancers13174361] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Accepted: 08/23/2021] [Indexed: 01/05/2023] Open
Abstract
The rates of microscopic incomplete resections (R1/R0CRM+) in patients receiving standard pancreaticoduodenectomy for PDAC remain very high. One reason may be the reported high rates of mesopancreatic fat infiltration. In this large cohort study, we used available histopathological specimens of the retropancreatic fat and correlated high resolution CT-scans with the microscopic tumor infiltration of this area. We found that preoperative MDCT scans are suitable to detect cancerous infiltration of this mesopancreatic tissue and this, in turn, was a significant indicator for both incomplete surgical resection (R1/R0CRM+) and worse overall survival. These findings indicate that a neoadjuvant treatment in PDAC patients with CT-morphologically positive infiltration of the mesopancreas may result in better local control and thus improved resection rates. Mesopancreatic fat stranding should thus be considered in the decision for neoadjuvant therapy. Background: Due to the persistently high rates of R1 resections, neoadjuvant treatment and mesopancreatic excision (MPE) for ductal adenocarcinoma of the pancreatic head (hPDAC) have recently become a topic of interest. While radiographic cut-off for borderline resectability has been described, the necessary extent of surgery has not been established. It has not yet been elucidated whether pre-operative multi-detector computed tomography (MDCT) staging reliably predicts local mesopancreatic (MP) fat infiltration and tumor extension. Methods: Two hundred and forty two hPDAC patients that underwent MPE were analyzed. Radiographic re-evaluation was performed on (1) mesopancreatic fat stranding (MPS) and stranding to peripancreatic vessels, as well as (2) tumor diameter and anatomy, including contact to peripancreatic vessels (SMA, GDA, CHA, PV, SMV). Routinely resected mesopancreatic and perivascular (SMA and PV/SMV) tissue was histopathologically re-analyzed and histopathology correlated with radiographic findings. A logistic regression of survival was performed. Results: MDCT-predicted tumor diameter correlated with pathological T-stage, whereas presumed tumor contact and fat stranding to SMA and PV/SMV predicted and correlated with histological cancerous infiltration. Importantly, mesopancreatic fat stranding predicted MP cancerous infiltration. Positive MP infiltration was evident in over 78%. MPS and higher CT-predicted tumor diameter correlated with higher R1 resection rates. Patients with positive MP stranding had a significantly worse overall survival (p = 0.023). Conclusions: A detailed preoperative radiographic assessment can predict mesopancreatic infiltration and tumor morphology and should influence the decision for primary surgery, as well as the extent of surgery. To increase the rate of R0CRM- resections, MPS should be considered in the decision for neoadjuvant therapy.

Mesopancreatic excision for pancreatic ductal adenocarcinoma improves local disease control and survival. Pancreatology 2021; 21:787-795.

Abstract
BACKGROUND Survival in ductal adenocarcinoma of the pancreatic head (hPDAC) is poor. After implementation of the circumferential resection margin (CRM) into standard histopathological evaluation, the margin negative resection rate has drastically dropped. However, the impact of surgical radicality on survival and the influence of malignant infiltration of the mesopancreatic fat remains unclear. At our institution, a standardized dissection of the mesopancreatic lamina and peri-pancreatic vessels are obligatory components of radical pancreatoduodenectomy. The aim of our study was to histopathologically analyze mesopancreatic tumor infiltration and the influence of CRM-evaluated resection margin on relapse-free and overall survival. METHOD Clinicopathological and survival parameters of 264 consecutive patients who underwent surgery for hPDAC were evaluated. RESULTS The rate of R0 resection R0(CRM-) was 48.5%, after the implementation of CRM. Mesopancreatic fat infiltration was evident in 78.4% of all consecutively treated patients. Patients with mesopancreatic fat infiltration were prone to lymphatic metastases (N1 and N2) and had a higher rate of positive resection margin (R1/R0(CRM+)). In multivariate analysis, only R0 resection was shown to be an independent prognostic parameter. Local recurrence was diagnosed in only 21.1% and was significantly lower in patients with R0(CRM-) resected hPDACs (10.9%, p < 0.001). CONCLUSION Mesopancreatic excision is justified, since mesopancreatic fat invasion was evident in the majority of our patients. It is associated with a significantly improved local tumor control as well as longer relapse-free and overall survival.

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.

What Should Guide the Performance of Venous Resection During Pancreaticoduodenectomy for Pancreatic Ductal Adenocarcinoma with Venous Contact? Ann Surg Oncol 2021; 28:6211-6222.

Abstract
Complete surgical resection, most often associated with perioperative chemotherapy, is the only way to offer a chance of cure for patients with pancreatic cancer. One of the most important factors in determining survival outcome that can be influenced by the surgeon is the R0 resection. However, the proximity of mesenteric vessels in cephalic pancreatic tumors, especially the mesenterico-portal venous axis, results in an increased risk of vein involvement and/or the presence of malignant cells in the venous bed margin. A concomitant venous resection can be performed to decrease the risk of a positive margin. Given the additional technical difficulty that this implies, many surgeons seek a path between the tumor and the vein, hoping for the absence of tumor infiltration into the perivascular tissue on pathologic analysis, particularly in cases with administration of neoadjuvant therapy. The definition of optimal surgical margin remains a subject of debate, but at least 1 mm is an independent predictor of survival after pancreatic cancer surgical resection. Although preoperative radiologic assessment is essential for accurate planning of a pancreatic resection, intraoperative decision-making with regard to resection of the mesenterico-portal vein in tumors with a venous contact remains unclear and variable. Although venous histologic involvement and perivascular infiltration are not accurately predictable preoperatively, clinicians must examine the existing criteria and normograms to guide their surgical management according to the integration of new imaging techniques, preoperative chemotherapy use, tumor biology and molecular histopathology, and surgical techniques.

Abstract
Background To analyze the related factors affecting the prognosis of pancreatic carcinoma with portal system invasion. Methods We retrospectively analyzed the clinical data of 118 patients with portal venous system invasion in Beijing Chaoyang Hospital between January 2011 and December 2018. Only patients with borderline resectable pancreatic cancer were included in this study. Borderline pancreatic cancer was defined according to NCCN (The National Comprehensive Cancer Network) guidelines. All patients underwent surgical treatment combined with vascular resection and reconstruction. The prognosis was evaluated according to the follow-up results, and the related risk factors for prognosis were analyzed. The survival curve was drawn by Kaplan-Meier method, and the survival rate was compared by log-rank test. Multivariate Cox regression was used to analyze the prognostic factors. Results In our research, all of 126 patients were successfully completed the operations. Complications occurred in 29.7% of patients and perioperative death in 4.0%. A total of 118 patients were followed up and the followed-up rate was 97.5% (118/121). The overall 1-year, 2-year and 3-year survival rates were 49.2%, 27.1% and 19.8%, And the median survival time was 20 months. Multivariate analysis showed that preoperative CA19-9 (RR 1.449, 95% CI: 1.053-1.994), N status (RR 2.533, 95% CI: 1.337-4.798), degree of tumor differentiation (RR 1.592, 95% CI: 1.064-2.381) and venous invasion depth (RR 2.03, 95% CI: 1.504-2.758) were independent risk factors for the prognosis. Conclusions The long-term prognosis of pancreatic carcinoma patients with portal system invasion is poor. The venous invasion depth is an independent risk factor for the prognosis of pancreatic carcinoma with portal system invasion, the deeper of venous invasion, the worse the prognosis, and poorly differentiated tumors have the worst prognosis. Other independent risk factors included N status and the preoperative CA19-9. Those may help with patients' selection for different treatment protocols.

Abstract
Objectives To develop a radiomics signature for predicting surgical portal vein-superior mesenteric vein (PV-SMV) in patients with pancreatic ductal adenocarcinoma (PDAC) and measure the effect of providing the predictions of radiomics signature to radiologists with different diagnostic experiences during imaging interpretation. Methods Between February 2008 and June 2020, 146 patients with PDAC in pancreatic head or uncinate process from two institutions were retrospectively included and randomly split into a training (n = 88) and a validation (n =58) cohort. Intraoperative vascular exploration findings were used to identify surgical PV-SMV invasion. Radiomics features were extracted from the portal venous phase CT images. Radiomics signature was built with a linear elastic-net regression model. Area under receiver operating characteristic curve (AUC) of the radiomics signature was calculated. A senior and a junior radiologist independently review CT scans and made the diagnosis for PV-SMV invasion both with and without radiomics score (Radscore) assistance. A 2-sided Pearson's chi-squared test was conducted to evaluate whether there was a difference in sensitivity, specificity, and accuracy between the radiomics signature and the unassisted radiologists. To assess the incremental value of providing Radscore predictions to the radiologists, we compared the performance between unassisted evaluation and Radscore-assisted evaluation by using the McNemar test. Results Numbers of patients identified as presence of surgical PV-SMV invasion were 33 (37.5%) and 19 (32.8%) in the training and validation cohort, respectively. The radiomics signature achieved an AUC of 0.848 (95% confidence interval, 0.724-0.971) in the validation cohort and had a comparable sensitivity, specificity, and accuracy as the senior radiologist in predicting PV-SMV invasion (all p-values > 0.05). Providing predictions of radiomics signature increased both radiologists' sensitivity in identifying PV-SMV invasion, while only the increase of the junior radiologist was significant (63.2 vs 89.5%, p-value = 0.025) instead of the senior radiologist (73.7 vs 89.5%, p-value = 0.08). Both radiologists' accuracy had no significant increase when provided radiomics signature assistance (both p-values > 0.05). Conclusions The radiomics signature can predict surgical PV-SMV invasion in patients with PDAC and may have incremental value to the diagnostic performance of radiologists during imaging interpretation.

Cytokeratin-positive cells in the bone marrow from patients with pancreatic, periampullary malignancy and benign pancreatic disease show no prognostic information. BMC Cancer 2020; 20:1107. [PMID: 33198661 PMCID: PMC7667773 DOI: 10.1186/s12885-020-07510-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Accepted: 10/07/2020] [Indexed: 12/11/2022] Open
Abstract
Background Pancreatic and periampullary carcinoma are aggressive tumours where preoperative assessment is challenging. Disseminated tumour cells (DTC) in the bone marrow (BM) are associated with impaired prognosis in a variety of epithelial cancers. In a cohort of patients with presumed resectable pancreatic and periampullary carcinoma, we evaluated the frequency and the potential prognostic impact of the preoperative presence of DTC, defined as cytokeratin-positive cells detected by immunocytochemistry (ICC). Methods Preoperative BM samples from 242 patients selected for surgical resection of presumed resectable pancreatic and periampullary carcinoma from 09/2009 to 12/2014, were analysed for presence of CK-positive cells by ICC. The median observation time was 21.5 months. Overall survival (OS) and disease-free survival (DFS) were calculated by Kaplan-Meier and Cox regression analysis. Results Successful resections of malignant tumours were performed in 179 of the cases, 30 patients resected had benign pancreatic disease based on postoperative histology, and 33 were deemed inoperable intraoperatively due to advanced disease. Overall survival for patients with resected carcinoma was 21.1 months (95% CI: 18.0–24.1), for those with benign disease OS was 101 months (95% CI: 69.4–132) and for those with advanced disease OS was 8.8 months (95% CI: 4.3–13.3). The proportion of patients with detected CK-positive cells was 6/168 (3.6%) in resected malignant cases, 2/31 (6.5%) in advanced disease and 4/29 (13.8%) in benign disease. The presence of CK-positive cells was not correlated to OS or DFS, neither in the entire cohort nor in the subgroup negative for circulating tumour cells (CTC). Conclusions The results indicate that CK-positive cells may be present in both patients with malignant and benign diseases of the pancreas. Detection of CK-positive cells was not associated with differences in prognosis for the entire cohort or any of the subgroups analysed. Trial registration clinicaltrials.gov (NCT01919151).

Systematic review and meta-analysis of contemporary pancreas surgery with arterial resection. Langenbecks Arch Surg 2020; 405:903-919. [PMID: 32894339 PMCID: PMC7541389 DOI: 10.1007/s00423-020-01972-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Accepted: 08/19/2020] [Indexed: 12/19/2022]
Abstract
Objective Advances in multimodality treatment paralleled increasing numbers of complex pancreatic procedures with major vascular resections. The aim of this meta-analysis was to evaluate the current outcomes of arterial resection (AR) in pancreatic surgery. Methods A systematic literature search was carried out from January 2011 until January 2020. MOOSE guidelines were followed. Predefined outcomes were morbidity, pancreatic fistula, postoperative bleeding and delayed gastric emptying, reoperation rate, mortality, hospital stay, R0 resection rate, and lymph node positivity. Duration of surgery, blood loss, and survival were also analyzed. Results Eight hundred and forty-one AR patients were identified in a cohort of 7111 patients. Morbidity and mortality rates in these patients were 66.8% and 5.3%, respectively. Seven studies (579 AR patients) were included in the meta-analysis. Overall morbidity (48% vs 39%, p = 0.1) and mortality (3.2% vs 1.5%, p = 0.27) were not significantly different in the groups with or without AR. R0 was less frequent in the AR group, both in patients without (69% vs 89%, p < 0.001) and with neoadjuvant treatment (50% vs 86%, p < 0.001). Weighted median survival was shorter in the AR group (18.6 vs 32 months, range 14.8–43.1 months, p = 0.037). Conclusions Arterial resections increase the complexity of pancreatic surgery, as demonstrated by relevant morbidity and mortality rates. Careful patient selection and multidisciplinary planning remain important.

Abstract
Introduction: Vascular resection remains a subject of debate in the management of Pancreatic Ductal Adenocarcinoma (PDAC). These French recommendations were drafted on behalf of the French National Institute of Cancer (INCA-2019). Material and Methods: A systematic literature search, with PubMed, Medline® (OvidSP), EMBASE, the Cochrane Library, was performed for abstracts published in English from January 2008 to June 2019, and identified systematic reviews/metaanalyses, retrospective analyses and case series dedicated to vascular resections in the setting of PDAC. All selected articles were graded for level of evidence and strength of recommendation was given according to the GRADE system. Results: Neoadjuvant treatment should be performed rather than direct surgery in borderline and locally advanced non-metastatic PDAC with venous and/or arterial infiltration (T4 stage). Patients who respond or those with stable disease and good performance status should undergo surgical exploration to assess resectability because cross-sectional imaging often fails to identify the extent of the remaining viable tumor. Combining vascular resection with pancreatectomy in these cases increases the feasibility of curative resection which is still the only option to improve long-term survival. Venous resection (VR) is recommended if resection is possible in the presence of limited lateral or circumferential involvement but without venous occlusion and in the absence of arterial contact with the celiac axis (CA; cephalic tumors) or the superior mesenteric artery (SMA; all tumor locations) (Grade B). The patients should be in good general condition because mortality and morbidity are higher than following pancreatectomy without VR (Grade B). In case of planned VR, neoadjuvant treatment is recommended since it improves both rate of R0 resections and survival compared to upfront surgery (Grade B). Due to their complexity and specificities, arterial resection (AR; mainly the hepatic artery (HA) or the CA) must be discussed in selected patients, in multidisciplinary team meetings in tertiary referral centers, according to the tumor location and the type of arterial extension. In case of invasion of a short segment of the common HA, resection with arterial reconstruction may be proposed after neoadjuvant therapy. In case of SMA invasion, neoadjuvant therapy may be followed by laparotomy with dissection and biopsy of peri-arterial tissues. A pancreaticoduodenectomy (PD) with SMA-resection is not recommended if the frozen section examination is positive (Grade C). In case of distal PDAC with invasion of the CA, a distal pancreatectomy with CA-resection without arterial reconstruction may be proposed after neoadjuvant therapy and radiologic embolization of the CA branches (expert opinion). Conclusion: For PDAC with vascular involvement, neoadjuvant treatment followed by pancreatectomy with venous resection or even arterial resection can be proposed as a curative option in selected patients with selected vascular involvement.

World J Gastroenterol 2019; 25:6752-6766. [PMID: 31857777 PMCID: PMC6920658 DOI: 10.3748/wjg.v25.i46.6752] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2019] [Revised: 11/12/2019] [Accepted: 11/29/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The 8th edition of the American Joint Committee on Cancer (AJCC) staging system for pancreatic ductal adenocarcinoma (PDAC) excludes extrapancreatic extension from the assessment of T stage and restages tumors with mesenterico-portal vein (MPV) invasion into T1-3 diseases according to tumor size. However, MPV invasion is believed to be correlated with a poor prognosis.
AIM To analyze whether the inclusion of MPV invasion can further improve the 8th edition of the AJCC staging system for PDAC.
METHODS This study retrospectively included 8th edition AJCC T1-3N0-2M0 patients undergoing pancreaticoduodenectomy/total pancreatectomy from two cohorts and analyzed survival outcomes. In the first cohort, a total of 7539 patients in the surveillance, epidemiology, and end results database was included, and in the second cohort, 689 patients from the West China Hospital database were enrolled.
RESULTS Cox regression analysis showed that MPV invasion is an independent prognostic factor in both databases. In the MPV- group, all pairwise comparisons between the survival functions of patients with different stages were significant except for the comparison between patients with stage IIA and those with stage IIB. However, in the MPV+ group, pairwise comparisons between the survival functions of patients with stage IA, stage IB, stage IIA, stage IIB, and stage III were not significant. T1-3N0 patients in the MPV+ group were compared with the T1N0, T2N0, and T3N0 subgroups of the MPV- group; only the survival of MPV-T3N0 and MPV+T1-3N0 patients had no significant difference. Further comparisons of patients with stage IIA and subgroups of stage IIB showed (1) no significant difference between the survival of T2N1 and T3N0 patients; (2) a longer survival of T1N1 patients that was shorter than the survival of T2N0 patients; and (3) and a shorter survival of T3N1 patients that was similar to that of T1-3N2 patients.
CONCLUSION The modified 8th edition of the AJCC staging system for PDAC proposed in this study, which includes the factor of MPV invasion, provides improvements in predicting prognosis, especially in MPV+ patients.

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
Pancreatic ductal adenocarcinoma (PDAC) is an aggressive, lethal malignancy that invades adjacent vasculatures and spreads to distant sites before clinical detection. Although invasion into the peripancreatic vasculature is one of the hallmarks of PDAC, paradoxically, PDAC tumors also exhibit hypovascularity. How PDAC tumors become hypovascular is poorly understood. We describe an organotypic PDAC-on-a-chip culture model that emulates vascular invasion and tumor-blood vessel interactions to better understand PDAC-vascular interactions. The model features a 3D matrix containing juxtaposed PDAC and perfusable endothelial lumens. PDAC cells invaded through intervening matrix, into vessel lumen, and ablated the endothelial cells, leaving behind tumor-filled luminal structures. Endothelial ablation was also observed in in vivo PDAC models. We also identified the activin-ALK7 pathway as a mediator of endothelial ablation by PDAC. This tumor-on-a-chip model provides an important in vitro platform for investigating the process of PDAC-driven endothelial ablation and may provide a mechanism for tumor hypovascularity.

Abstract
BACKGROUND The International Study Group of Pancreatic Surgery (ISGPS) recommends operative exploration and resection of pancreatic cancers in the presence of reconstructable mesentericoportal axis involvement. However, there is no consensus on the ideal method of vascular reconstruction. The effect of depth of tumour invasion of the vessel wall on outcome is also unknown. METHODS This was a retrospective cohort study of pancreaticoduodenectomy with vein resection for T3 adenocarcinoma of the head of the pancreas across nine centres. Outcome measures were overall survival based on the impact of the depth of tumour infiltration of the vessel wall, and morbidity, in-hospital mortality and overall survival between types of venous reconstruction: primary closure, end-to-end anastomosis and interposition graft. RESULTS A total of 229 patients underwent portal vein resection; 129 (56·3 per cent) underwent primary closure, 64 (27·9 per cent) had an end-to-end anastomosis and 36 (15·7 per cent) an interposition graft. There was no difference in overall morbidity (26 (20·2 per cent), 14 (22 per cent) and 9 (25 per cent) respectively; P = 0·817) or in-hospital mortality (6 (4·7 per cent), 2 (3 per cent) and 2 (6 per cent); P = 0·826) between the three groups. One hundred and six patients (47·5 per cent) had histological evidence of vein involvement; 59 (26·5 per cent) had superficial invasion (tunica adventitia) and 47 (21·1 per cent) had deep invasion (tunica media or intima). Median survival was 18·8 months for patients who had primary closure, 27·6 months for those with an end-to-end anastomosis and 13·0 months among patients with an interposition graft. There was no significant difference in median survival between patients with superficial, deep or no histological vein involvement (20·8, 21·3 and 13·3 months respectively; P = 0·111). Venous tumour infiltration was not associated with decreased overall survival on multivariable analysis. CONCLUSION In this study, there was no difference in morbidity between the three modes of venous reconstruction, and overall survival was similar regardless of tumour infiltration of the vein.

Circulating and disseminated tumor cells in pancreatic cancer and their role in patient prognosis: a systematic review and meta-analysis. Oncotarget 2017; 8:107223-107236.

Abstract
Background Disseminated tumor cells (DTCs) and circulating tumor cells (CTCs) have been postulated to seed metastases and contribute to poorer patient outcomes in many types of solid cancer. To date, no systematic reviews have examined the role of both DTCs and CTCs in pancreatic cancer. We aimed to determine the prognostic value of DTCs/CTCs in pancreatic cancer using a systematic review and meta-analysis. Materials and Methods A comprehensive literature search identified studies examining DTCs and CTCs in the bone marrow and blood of pancreatic cancer patients at diagnosis with follow-up to determine disease-free/progression-free survival (DFS/PFS) and overall survival (OS). Statistical analyses were performed to determine the hazard ratio (HR) of DTCs/CTCs on DFS/PFS and OS. Results The literature search identified 16 articles meeting the inclusion criteria. The meta-analysis demonstrated statistically significant HR differences in DFS/PFS (HR = 1.93, 95% CI 1.19–3.11, P = 0.007) and OS (HR = 1.84, 95% CI 1.37–2.45, P =< 0.0001), indicating patients with detectable DTCs/CTCs at diagnosis have worse prognoses. Subgroup analyses suggested CTCs in the peripheral blood (HR =2.03) were more indicative of poor OS prognosis than DTCs in the bone marrow (HR = 1.91), although the difference between these was not statistically significant. Positivity of the CellSearch detection method for DTC/CTC had the highest correlation with decreased OS (HR = 2.79) while immunodetection (HR = 1.91) and RT-PCR (HR = 1.25) were less effective in determining prognosis. Conclusion The detection of DTCs/CTCs at diagnosis is associated with poorer DFS/PFS and OS in pancreatic cancer.

Abstract
Extension of pancreatic adenocarcinoma into adjacent vasculature often necessitates resection of the portal vein (PV) and or superior mesenteric vein (SMV) during pancreaticoduodenectomy (PD). Our study describes the surgical technique and results of PV/SMV resection in pancreatic adenocarcinoma patients. Between January 2008 and October 2013, 252 patients underwent PD for pancreatic malignancy. A total of 42 PV/SMV resections were performed (28 men, 14 women). Patients were categorized into 2 groups according to the degree of invasion into the portal vein wall: Group A (n = 16), extended compression of the portal vein wall by the surrounding carcinoma without true invasion, and Group B (n = 26), true invasion including intramural and transmural invasion. Morbidity of the 42 patients was 35%; there was no operative mortality, and overall 1-, 3-, and 5-year survival rates were 60%, 21%, and 12%, respectively. No differences in tumor size, margin positivity, nodal positivity, or survival rates were observed between groups. Resection of the PV/SMV is safe and does not increase morbidity or mortality. Tumor involvement of the PV/SMV is not associated with histopathologic signs that are predictive of a poor prognosis. The “artery first” approach should be considered as a means to facilitate safe venous resection and reconstruction.

Abstract
BACKGROUND Resection of the superior mesenteric artery (SMA) during pancreatectomy is performed infrequently and is undertaken with the aim of removing non-metastatic locally advanced pancreatic tumours. SMA resection reports also encompass resection of other visceral vessels. The consequences of resection of these different arteries are not necessarily equivalent. This is a focused systematic review of the outcome of SMA resection during pancreatectomy for cancer. METHODS A computerized search of the English language literature was undertaken for the period 1st January 2000 through 30th April 2016. The keywords "Pancreatic surgery" and "Vascular resections" were used. Thirteen studies reported 70 patients undergoing pancreatectomy with SMA resection from 10,726 undergoing pancreatectomy. Individual patient-level outcome data were available for 25. RESULTS Median (range) accrual period was 132 (48-372) months. Reported peri-operative morbidity ranged from 39% to 91%. There were 5 peri-operative deaths in the 25 patients with individual-outcome data. Median survival was 11 months (95% Confidence interval 9.5-12.5 months; standard error 0.8 months). CONCLUSIONS SMA resection during pancreatectomy is undertaken infrequently incurring high peri-operative morbidity and mortality. Median survival is 11 (95% CI 9.5-12.5) months. In contemporary practice there is no evidence to support SMA resection during pancreatectomy.

Abstract
BACKGROUND Incomplete evaluation of venous invasion has led to conflicting results regarding the prognosis of patients undergoing pancreatectomy with a synchronous venous resection. This study evaluates the prognostic value associated with the presence and the depth of venous invasion in T3 pancreatic adenocarcinoma. METHODS This study evaluated retrospectively 181 consecutive pancreatoduodenectomies performed for T3N0M0 and T3N1M0 pancreatic adenocarcinomas (stages IIA and IIB) from January 2006 to December 2014. Univariate and multivariate Cox analyses were performed to assess survival prognostic factors. RESULTS Pancreatoduodenectomies with a segmental venous resection was performed on 91 patients, while 90 other patients had a standard pancreatoduodenectomies without venous resection. Pathologic venous invasion was detected in 68 (74%) of the 91 venous resection patients. Depth of venous invasion was into the adventitia (n = 25), media (n = 28), and intima (n = 15). The overall survival rates at 1, 3, 5, and 10 years were 75%, 33%, 21%, and 6%, respectively. There were no differences in survival between patients undergoing standard pancreatoduodenectomies and pancreatoduodenectomies with venous resection (27 vs 22 months; P = .28) or between patients with and without venous invasion (20 vs 27 months; P = .08). In multivariate analysis, depth of venous invasion into the intima (hazard ratio, 2.25; 95% confidence interval, 1.16-4.34; P = .0001) and adjuvant chemotherapy (hazard ratio, 0.16; 95% confidence interval, 0.09-0.43; P ≤ .0001) were identified as independent prognostic factors of overall survival. CONCLUSION Depth of venous invasion into the intima indicates poor survival in pancreatic T3 adenocarcinoma. Preoperative identification of this factor could be helpful for better selection of patients for curative operation.

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
BACKGROUND Pancreaticoduodenectomy with superior mesenteric/portal venous resection for pancreatic ductal adenocarcinoma (PDAC) is frequently performed with no added morbidity or mortality in case of tumor abutment to the superior mesenteric or portal vein so as to obtain a margin negative resection. True histopathological portal vein invasion is found only in a small subset of such patients. The aim of this review aimed to discuss the significance of histopathological venous invasion in PDAC. DATA SOURCES For this review available data was searched from PubMed and analyzed. No randomized trials have been published on this topic. RESULTS Existing data on prognostic factors in histopathological venous invasion by PDAC are limited and recent studies indicate worse survival in this subgroup of patients. In addition, venous invasion in PDAC has been associated with large tumors, involved lymph nodes, perineural invasion and R1 resection. The survival of patients with portal venous resection but without histologic venous invasion is reportedly better than those with histopathological venous invasion; though conflicting studies do exist on the subject. Some studies also relate the depth of venous invasion to prognosis after surgical resection of PDAC. CONCLUSIONS Frank/'histopathological' invasion of superior mesenteric/portal venous and R1 resection indicate a very poor survival. Such patients may be given the opportunity of benefit of neoadjuvant treatment.

Abstract
Pancreatic ductal adenocarcinoma carries a poor prognosis with annual deaths almost matching the reported incidence rates. Surgical resection offers the only potential cure. Yet, even among patients that undergo tumor resection, recurrence rates are high and long-term survival is scarce. Various tumor-related factors have been identified as predictors of survival after potentially curative resection. These factors include tumor size, lymph node disease, tumor grade, vascular invasion, perineural invasion and surgical resection margin. This article will re-evaluate the importance of these factors based on recent publications on the topic, with potential implications for treatment and outcome in patients with pancreatic cancer.

Abstract
As angiogenesis is an important target for antitumour drugs, the agents that inhibit angiogenesis may help reduce the use of chemotherapy by blocking tumour blood supply. In this study, we investigated a potent angiogenesis inhibitor, ASC, a steroidal saponin compound, which has been purified from Ophitopogin japonicus (L.f) Ker.-Gawl. Our observations showed that ASC significantly suppressed human umbilical vein endothelial cell (HUVECs) growth both in vitro and in vivo. This may be resulted from the G2/M cell cycle arrest effects of ASC. Moreover, ASC inhibited HUVECs invasion and tube formation processes, which were associated with endothelial cells remodelling. A mechanism study indicated that ASC down-regulated the expression of Src tyrosine kinase, further leading to the blockage of Akt-dependent matrix metalloproteinases (mainly for MMP-9) signalling pathway, which was functionally associated with angiogenic blood vessels. Finally, ASC significantly inhibited angiogenesis and MMPs/VEGF expression in the subcutaneously injected matrigel in C57/BL mice. These findings suggest that ASC might be a potential drug candidate in anti-angiogenesis and anticancer therapies.

Abstract
Traditionally, pancreatic ductal adenocarcinoma with regional vascular involvement was thought to represent unresectable disease and was associated with disease progression and death within 1 year of diagnosis. Recent evidence demonstrates that pancreaticoduodenectomy with vascular resection and reconstruction can be safely performed in select patients with 5-year survival rates as high as 20%. In order to safely treat and to optimize survival in these complex patients, it is essential to accurately identify vascular involvement preoperatively, to utilize a multidisciplinary treatment approach, and to emphasize meticulous surgical technique with awareness of the critical margins of resection.

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 Although pancreatoduodenectomy (PD) with mesenterico-portal vein resection (VR) can be performed safely in patients with resectable pancreatic ductal adenocarcinoma (PDAC), the impact of this approach on long-term survival is controversial. PATIENTS AND METHODS Analyses of a prospectively collected database revealed 122 consecutive patients with PDAC who underwent PD with (PD+VR) or without (PD-VR) VR between January 2004 and May 2012. Clinical data, operative results, and survival outcomes were analysed. RESULTS Sixty-four (53 %) patients underwent PD+VR. The majority (84 %) of the venous reconstructions were performed with a primary end-to-end anastomosis. Demographic and postoperative outcomes were similar between the two groups. American Society of Anesthesiologists (ASA) score, duration of operation, intraoperative blood loss, and blood transfusion requirement were significantly greater in the PD+VR group compared with the PD-VR group. Furthermore, the tumor size was larger, and the rates of periuncinate neural invasion and positive resection margin were higher in the PD+VR group compared with the PD-VR group. Histological venous involvement occurred in 47 of 62 (76 %) patients in the PD+VR group. At a median follow-up of 29 months, the median overall survival (OS) was 18 months for the PD+VR group, and 31 months for the PD-VR group (p = 0.016). ASA score, lymph node metastasis, neurovascular invasion, and tumor differentiation were predictive of survival. The need for VR in itself was not prognostic of survival. CONCLUSIONS PD with VR has similar morbidity but worse OS compared with a PD-VR. Although VR is not predictive of survival, tumors requiring a PD+VR have more adverse biological features.

Abstract
BACKGROUND Pancreatic carcinoma is one of the leading causes of cancer-related mortality. At the time of diagnosis, 30% of patients present with a locally advanced pancreatic carcinoma (LAPC). As circulating tumor cells (CTCs) count may be a surrogate of the cancer metastatic abilities, CTC detection rates and prognostic value were studied in a prospective cohort of LAPC patients. PATIENTS AND METHODS An LAP07 international multicenter randomized study assesses in patients whose LAPC is controlled after 4 months of chemotherapy whether chemoradiotherapy could increase survival versus continuation of chemotherapy. A subgroup of patients included in the LAP07 trial was screened for CTCs (CellSearch®) before the start of the chemotherapy and after 2 months of treatment. Patient characteristics and survival were obtained prospectively and were correlated with CTC detection. RESULTS Seventy-nine patients were included. One or more CTCs/7.5 ml were detected in 5% of patients before treatment and in 9% of patients after 2 months of treatment (overall detection rate: 11% of patients). CTC positivity was associated with poor tumor differentiation (P = 0.04), and with shorter overall survival (OS) in multivariable analysis (RR = 2.5, P = 0.01), together with anemia. CONCLUSIONS The evaluation of micrometastatic disease using CTC detection appears as a promising prognostic tool in LAPC patients.

Abstract
Abstract Objective. The first objective of the present study was to identify opportunities of improvement for clinical practice, assessed by local quality indicators, then to analyze possible reasons why we did not reach defined treatment quality measures. The second objective was to characterize patients, considered unresectable according to present criteria, for future arrangement of interventional studies with improved patient selection. Material and methods. Prospective observational cohort study from October 2008 to December 2010 of patients referred to the authors' institution with suspected pancreatic or periampullary neoplasm. Results. Of 330 patients, 135 underwent surgery, 195 did not, 129 due to unresectable malignancies. The rest had benign lesions. Perioperative morbidity rate was 32.6%, mortality 0.7%. Radical resection (R0) was obtained in 23 (41.8%) of 55 patients operated for pancreatic adenocarcinoma and 6.3% underwent reconstructive vascular surgery. Diagnostic failure/delay resulted in unresectable carcinoma, primarily misconceived as serous cystic adenoma in two patients. One resected lesion turned out to be focal autoimmune pancreatitis. One case with misdiagnosed cancer was revised to be a pseudoaneurysm. Palliative treatment was offered to 144 patients with malignant tumors, 62 due to locally advanced disease and all pancreatic adenocarcinomas. Conclusions. Quality improvement opportunities were identified for patient selection and surgical technique: Too few patients underwent reconstructive vascular surgery. The most important quality indicators are those securing resectional, radical (R0) surgery. Altogether 143 patients (57.9%) of those with malignant tumors were found unresectable, most of these patients are eligible for inclusion in future interventional studies with curative and/or palliative intention.

Improved survival and quality of life in patients undergoing R1 pancreatic resection compared to patients with locally advanced unresectable pancreatic adenocarcinoma. Pancreatology 2013; 13:180-5. [PMID: 23561977 DOI: 10.1016/j.pan.2013.01.003] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2012] [Revised: 12/21/2012] [Accepted: 01/16/2013] [Indexed: 02/05/2023]
Abstract
OBJECTIVE To prospectively record the clinical consequences of R1 resection of pancreatic adenocarcinoma compared to patients with locally advanced tumours not undergoing surgery. BACKGROUND Surgery is the only potentially curative treatment of pancreatic cancer, and postoperative safety is increasing. The rate of R1 resections might also increase unintentionally as surgical procedures with curative goal become more comprehensive, and the clinical outcome requires further prospective evaluation. MATERIAL AND METHODS Prospective observational cohort study from October 2008 to December 2010. Outcome after R1 resection (group 1, surgery, n = 32) and conservative palliative chemoradiation/endoscopy (group 2, no surgery, n = 56) is compared with survival and longitudinal patient-reported quality of life (QoL) as endpoints. QoL was assessed by the Edmonton Symptom Assessment System (ESAS). RESULTS Demographic characteristics and tumour diameters were similar in both groups: 38.0 (31.3, 49.8) mm in group 1 versus 44.0 (39.6, 49.1) mm in group 2 (p = 0.18). Perioperative morbidity was 25% with no mortality. Disease-specific survival was 18.0 (14.5, 23.8) months in group 1 versus 8.1 (4.8, 10.1) months in group 2 (p < 0.0001). Overall survival was 11 (7.8, 14.4) months. Reduction in fatigue was significantly improved in the surgery group 6, 12, and 19 weeks after baseline, whereas reduction in global health was significantly better in group 2. CONCLUSION Radical removal (R0 resection) is the primary aim of surgery, but also R1 resection seems to improve survival and QoL, compared to outcome in patients with locally advanced tumours not undergoing surgery.
