The benefit of adjuvant chemotherapy following pancreaticoduodenectomy for pancreatic adenocarcinoma depends on response to neoadjuvant therapy. J Surg Oncol 2024; 130:109-116. [PMID: 38801055 DOI: 10.1002/jso.27689] [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: 01/31/2024] [Revised: 04/15/2024] [Accepted: 05/11/2024] [Indexed: 05/29/2024]
Abstract
BACKGROUND The benefit of adjuvant therapy (AT) remains unclear in pancreatic ductal adenocarcinoma (PDAC) after neoadjuvant therapy (NAT) and surgical resection. METHODS The 2019 National Cancer Database was queried for patients with non-metastatic PDAC who received NAT followed by pancreaticoduodenectomy. Only patients with data regarding receipt of AT were included. Patients were classified if they had nodal down-staging specifically, or any downstaging (Tumor, Nodal, or overall). Propensity score matching (PSM) adjusted for pretreatment covariate imbalance between groups. The weighted Kaplan-Meier method and log-rank test were used to estimate the cumulative survival. RESULTS After exclusion criteria and PSM, a total of 2784 patients remained; 1689 (60.7%) received AT and 1095 (39.3%) did not receive AT. Among all, those with additional AT had a significantly improved overall survival (OS) (p < 0.001). Upon evaluation of patients without downstaging after NAT, those who received AT had improved OS (no nodal downstaging or any downstaging; p = 0.002; p = 0.001). When evaluating patients with downstaging after NAT, those receiving AT did not have improved OS (nodal downstaging or any downstaging: p = 0.352; p = 0.99). CONCLUSION Response to NAT appears to correlate with the benefit of AT following pancreaticoduodenectomy; patients who have a favorable response to NAT may not benefit from AT.

Abstract
Herein, we constructed the branch-shaped SiO2/nano GO (nGO)/Fe3O4/selenium quantum dots (QDs) (SeQDs) nanoparticles (SGF/SeQDs) embodying magnetism, fluorescence, and microwave stimulus response properties to enhance the performance of releasing drugs. The SGF/SeQDs composite was characterized by technologies including powder X-ray diffraction, transmission electron microscopy, infrared spectroscopy, etc. In the nanoparticles, the branch-shaped SiO2 provides a large specific surface area, nGO as the dielectric loss-style material promotes microwave-absorbing performance, and the Fe3O4 serves as a magnetic targeting agent and microwave absorber. Integrating nGO and Fe3O4 could further strengthen the microwave absorption of the entire composite; selenium features both fluorescence and anticancer effects. The synthesized nanoparticles as carriers exhibited a branch-like mesoporous sphere of ∼260 nm, a specific surface area of 258.57 m2 g-1, a saturation magnetization of 24.59 emu g-1, and good microwave thermal conversion performance that the temperature was elevated from 25 to 70 °C under microwave irradiation. These physical characteristics, including large pore volume (5.30 nm), high specific surface area, and fibrous morphology, are in favor of loading drugs. Meanwhile, the cumulative etoposide (VP16) loading rate of the nanoparticles reached to 21 wt % after 360 min. The noncovalent interaction between the VP16 and SGF/SeQDs was mainly the hydrogen-bonding effect during the loading process. Furthermore, the drug release rates at 180 min were up to 81.46, 61.92, and 56.84 wt % at pH 4, 5, and 7, respectively. At 25, 37, and 50 °C, the rates of drug release reach 25.40, 56.84, and 65.32 wt %, respectively. After microwave stimulation at pH 7, the rate of releasing drug increased distinctly from 56.84 to 71.74 wt % compared to that of nonmicrowave irradiation. Cytotoxicity tests manifested that the carrier had good biocompatibility. Therefore, the nanoparticles are looking forward to paving one platform for further applications in biomedicine and drug delivery systems.

Abstract
BACKGROUND The value of palliative surgery in pancreatic cancer is not well-defined. METHODS We queried the National Cancer Database for patients undergoing curative-intent resection, palliative surgery or medical palliation for clinical stage cT4N0-2M0 pancreatic cancer. Cohorts were 1:1:1 propensity-score-matched for comorbidities and stage. Kaplan-Meier method was used to compare overall survival for matched cohorts. RESULTS 9,107 patients met inclusion criteria: 3,567 (39 %) underwent curative intent surgery, 1608 (18 %) surgical palliation, 3932 (43 %) medical palliation. Patients undergoing resection and surgical palliation had significant hospitalizations (11.0 ± 0.4 vs. 10.0 ± 0.3 days; p = 0.821) and rates of readmission (8.1 % vs. 2.0 %; p < 0.001). Patients undergoing surgical palliation demonstrated marginal increases in survival relative to those undergoing medical palliation (8.54 vs. 7.36 months; p < 0.0001). CONCLUSION In patients undergoing care for locally advanced pancreatic cancer, palliative surgery is associated with marginal improvement in survival but significant lengths of hospitalization and risk of readmission.

Abstract
INTRODUCTION Neoadjuvant therapy (NT) is increasingly recommended for patients with localized pancreatic ductal adenocarcinoma (PDAC). Recent research has highlighted the significant treatment burden that patients experience during NT, but caregiver well-being during NT is poorly understood. METHODS A cross-sectional mixed-methods analysis of primary caregivers of patients with localized PDAC receiving NT was undertaken. All patients completed the Caregiver Quality of Life Index-Cancer (CQOLC) survey, while semi-structured interviews were conducted among a convenience sample of participants. RESULTS Among 28 caregivers, the mean age was 60.1 years, and most were patient spouses/significant others (71.4%). Patients had resectable (18%), borderline resectable (46%), or locally advanced (36%) PDAC with a mean treatment duration of 2.9 months at the time of their caregiver's enrollment. Most caregivers felt that they received adequate emotional/psychosocial support (80%) and understood the rationale for NT (93%). A majority (60%) reported that caregiving responsibilities impacted their daily lives and required a decrease in their work hours, leading to financial challenges (47%). While overall QOL was moderate (mean 83 ± 21.1, range 0-140), "emotional burden" (47.3 ± 20.9), and "positive adaption" (57.3 ± 13.9) were the lowest ranked CQOLC subsection scores. DISCUSSION Caregivers of patients with PDAC undergoing NT experience significant emotional symptoms and impact on their daily lives. Assessing caregiver needs and providing resources during NT should be a priority.

Abstract
Pancreatic cancer is one of the leading causes for cancer-related deaths in the United States. Majority of patients present with unresectable or metastatic disease. For those that present with localized disease, a multidisciplinary approach is necessary to maximize survival and optimize outcomes. The quality and safety of surgery for pancreatic cancer have improved in recent years with increasing adoption of minimally invasive techniques and surgical adjuncts. Systemic chemotherapy has also evolved to impact survival. It is now increasingly being utilized in the neoadjuvant setting, often with concomitant radiation. Increased utilization of genomic testing in metastatic pancreatic cancer has led to better understanding of their biology, thereby allowing clinicians to consider potential targeted therapies. Similarly, targeted agents such as PARP inhibitors and immune checkpoint- inhibitors have emerged with promising results. In summary, pancreatic cancer remains a disease with poor long-term survival. However, recent developments have led to improved outcomes and have changed practice in the past decade. This review summarizes current practices in pancreatic cancer treatment and the milestones that brought us to where we are today, along with emerging therapies.

Abstract
BACKGROUND There is an increasing use of neoadjuvant treatment (NAT) for pancreatic cancer (PC) followed by minimally invasive pancreatoduodenectomy (MIPD). We evaluate the impact of the surgical approach on 30-day outcomes in PC patients who underwent NAT. METHODS Patients with PC who had NAT followed by MIPD or open pancreatoduodenectomy (OPD) were identified from a pancreatectomy-targeted dataset (2014-2020) of the National Surgical Quality Improvement Program. Comparisons were made between MIPD and OPD within NAT groups. RESULTS A total of 5588 patients were analyzed. Of those, 4907 underwent OPD and 476 underwent MIPD. In addition, 3559 patients received neoadjuvant chemotherapy alone and 1830 received neoadjuvant chemoradiation. In the chemotherapy-alone group, the MIPD subgroup had lower rates of any complication (38.2% vs. 45.8%, P = 0.005), but there were no differences in mortality (2.1% for MIPD vs 1.9% for OPD, P=0.8) or serious complication (11.8% for MIPD vs 15% for OPD, P=0.1). On multivariable analysis, MIPD was independently predictive of lower rates of any complication (OR: 0.74, 95% CI 0.6-0.93, P = 0.0009), CR-POPF (OR: 0.58, 95% CI 0.35-0.96, P = 0.04), and shorter LOS (estimate: -1.03, 95% CI -1.73 to -0.32, P = 0.004). In the chemoradiation group, patients undergoing MIPD had higher rates of preoperative diabetes (P < 0.05), but there were no significant differences in any outcomes between the two approaches in this group. CONCLUSION MIPD is safe and feasible after NAT. Patients having neoadjuvant chemotherapy alone followed by MIPD had lower rates of complications, shorter LOS, and fewer CR-POPFs compared to OPD.

Abstract
Cancer is a complex and multifaceted disease that continues to be a global health challenge. It exerts a tremendous burden on individuals, families, healthcare systems, and society as a whole. To mitigate the impact of cancer, concerted efforts and collaboration on a global scale are essential. This includes strengthening preventive measures, promoting early detection, and advancing effective treatment strategies. In the field of cancer treatment, researchers and clinicians are constantly seeking new approaches and technologies to improve therapeutic outcomes and minimize adverse effects. One promising avenue of investigation is the utilization of the Fenton reaction, a chemical process that involves the generation of highly reactive hydroxyl radicals (·OH) through the interaction of hydrogen peroxide (H2O2) with ferrous ions (Fe2+). The generated ·OH radicals possess strong oxidative properties, which can lead to the selective destruction of cancer cells. In recent years, researchers have successfully introduced the Fenton reaction into the cancer microenvironment through the application of nanotechnology, such as polymer nanoparticles and light-responsive nanoparticles. This article reviews the progress of the application of the Fenton reaction, catalyzed by polymer nanoparticles and light-responsive nanoparticles, in the cancer microenvironment, as well as the potential applications and future development directions of the Fenton reaction in the field of tumor treatment.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is the most fatal cancer in humans, due to its difficulty of early detection and its high metastatic ability. The occurrence of epithelial to mesenchymal transition in preinvasive pancreatic lesions has been implicated in the early dissemination, drug resistance, and cancer stemness of PDAC. PDAC cells also have a reprogrammed metabolism, regulated by driver mutation-mediated pathways, a desmoplastic tumor microenvironment (TME), and interactions with stromal cells, including pancreatic stellate cells, fibroblasts, endothelial cells, and immune cells. Such metabolic reprogramming and its functional metabolites lead to enhanced mesenchymal plasticity, and creates an acidic and immunosuppressive TME, resulting in the augmentation of protumor immunity via cancer-associated inflammation. In this review, we summarize our recent understanding of how PDAC cells acquire and augment mesenchymal features via metabolic and immunological changes during tumor progression, and how mesenchymal malignancies induce metabolic network rewiring and facilitate an immune evasive TME. In addition, we also present our recent findings on the interesting relevance of the small G protein ADP-ribosylation factor 6-based signaling pathway driven by KRAS/TP53 mutations, inflammatory amplification signals mediated by the proinflammatory cytokine interleukin 6 and RNA-binding protein ARID5A on PDAC metabolic reprogramming and immune evasion, and finally discuss potential therapeutic strategies for the quasi-mesenchymal subtype of PDAC.

Abstract
Background Neoadjuvant therapy (NT), either with systemic treatment alone or in combination with radiation, is often utilized in the management of pancreatic adenocarcinoma to increase the likelihood of margin-negative resection. Following NT and resection, additional adjuvant chemotherapy (AC) can be considered for select patients and has been shown to improve overall survival (OS). This National Cancer Data Base (NCDB) analysis was performed to evaluate the outcomes of AC versus observation for resected pancreatic adenocarcinoma treated with NT. Methods The NCDB was queried for primary stage I-II cT1-3N0-1M0 resected pancreatic adenocarcinoma treated with NT (2004-2015). Baseline patient, tumor, and treatment characteristics were extracted. The primary endpoint was OS. With a 6-month conditional landmark, Kaplan-Meier analysis, multivariable Cox proportional hazards method, 1:1 propensity score matching were used to analyze the data. Results A total of 1737 eligible patients were identified, of which 1247 underwent postoperative observation compared to 490 with AC. The overall median follow-up was 34.7 months. The addition of AC showed improved survival on the multivariate analysis (HR 0.78, p<0.001). Of 490 propensity-matched pairs, all variables were well balanced, including age (p=0.61), Charlson-Deyo comorbidity score (p=0.80), ypT stage (p=0.93), ypN stage (p=0.83), surgical margin (p=0.83), duration of postoperative inpatient admission (p=0.96), and 30-day unplanned readmission after resection (p=0.34). AC remained statistically significant for improved OS, with median OS of 26.3 months vs 22.3 months and 2-year OS of 63.9% vs 52.9% for the observation cohort (p<0.001). Treatment interaction analysis showed OS benefit of AC for patients with smaller tumors (HR 0.67, p<0.001 for <3.1 cm vs HR 0.93, p=0.48 for ≥3.1 cm). Conclusion Using propensity score matched analysis, our findings suggest a survival benefit for adjuvant chemotherapy compared to observation following NT and surgery for resectable pancreatic adenocarcinoma, especially in patients with smaller tumors. Prospective studies are needed to identify subset of patients that would benefit from adjuvant chemotherapy.

Abstract
BACKGROUND Return to Intended Oncologic Treatment (RIOT) has been proposed as a quality metric in the care of cancer patients. We sought to define factors associated with inability to RIOT in Pancreatic Ductal Adenocarcinoma (PDAC) patients. METHODS The NCDB was queried for patients who underwent pancreaticoduodenectomy for pathologic stage IB, IIA, or IIB PDAC from 2010 to 2016. Multivariable binary logistic regression models identified factors associated with failure to RIOT, and Kaplan-Meier survival analysis and Cox multivariable regression models demonstrated the impact of failure to RIOT on survival. RESULTS Increasing age (p < .001), Hispanic race (p = .002), pathological stage IB (p = .004) and IIA (p = .001) as compared to IIB, increasing hospital stay (p < .001), and open surgical approach (p = .024) were associated with increased risk of inability to RIOT. Male sex (p < .001), Charlson-Deyo scores of 0 (p < .001) and 1 (p = .001) as compared to >2, negative surgical margins (p = .048), receiving care at academic institutions (p = .001), and increasing institutional case volume (p = .001) were associated with improved odds of RIOT. CONCLUSIONS Patient features can impact RIOT and should be considered when designing multi-modality treatment strategies.

Characterizing the patient experience during neoadjuvant therapy for pancreatic ductal adenocarcinoma: A qualitative study. World J Gastrointest Oncol 2022; 14:1175-1186. [PMID: 35949220 PMCID: PMC9244990 DOI: 10.4251/wjgo.v14.i6.1175] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 04/01/2022] [Accepted: 05/17/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Neoadjuvant therapy (NT) has increasingly been utilized for patients with localized pancreatic ductal adenocarcinoma (PDAC). It is the recommended approach for borderline resectable (BR) and locally advanced (LA) cancers and an increasingly utilized option for potentially resectable (PR) disease. Despite its increased use, little research has focused on patient-centered metrics among patients undergoing NT, including patient experiences, preferences, and recommendations. A better understanding of all aspects of the patient experience during NT may identify opportunities to design interventions aimed at improving quality of life; it may also facilitate the completion of NT and receipt of surgery, ultimately optimizing long-term outcomes. AIM To understand the experience of patients initiating and receiving NT to identify opportunities to improve neoadjuvant cancer care delivery. METHODS Semi-structured interviews of patients with localized PDAC during NT were conducted to explore their experience initiating and receiving NT. Interviews took place between August 2020 and October 2021. Due to the descriptive nature of the research, questions were open ended. Interviews were conducted over the phone, audio recorded and then transcribed. All interviews were coded by two independent researchers using NVivo 12, iteratively identifying themes until thematic saturation was achieved. An integrative approach to qualitative analysis was used, utilizing both inductive and deductive methods. RESULTS A total of 12 patients with localized PDAC were interviewed. Patients with BR (n = 7), PR (n = 2), and LA (n = 3) cancers participated in the study. All patients indicated that choosing NT was the doctor's recommendation, while most reported not being familiar with the concept of NT (n = 11) and that NT was presented as the only option (n = 8). Five themes describing the patient experience emerged: physical symptoms, emotional symptoms, coping mechanisms, access to care, and life factors. The most commonly cited recommendation for improving the experience of NT was improved education before and during NT (n = 7). Patients highlighted the need for more information on the rationale behind choosing NT prior to surgery, the anticipated surgery and its likelihood of surgery occurring after NT, as well as general information prior to starting NT treatment. The need for seeing different members of the healthcare team, including ancillary services was also frequently cited as a recommendation for improving the experience of NT (n = 5). CONCLUSION This study provides a framework to allow for a better understanding of the PDAC patient experience during NT and highlights opportunities to improve quality and quantity of life outcomes.

Abstract
BACKGROUND Neoadjuvant therapy (NT) is increasingly utilized for patients with localized pancreatic ductal adenocarcinoma (PDAC). Given the importance of completing multimodality therapy, the purpose of this qualitative study was to characterize physician perspectives on barriers and facilitators to delivering NT. METHODS A purposive sample of surgical, medical, and radiation oncologists participated in semi-structured interviews. Interviews were transcribed and coded by 3 independent researchers, iteratively identifying themes until saturation was achieved. RESULTS Participants (n = 27) were heterogeneous in specialty, years of experience, practice setting, gender, and geography. The most commonly cited advantage of NT was the ability to downstage patients. The most commonly cited barriers included lack of access and limited evidence. Patient preference for immediate surgery was frequently cited as a barrier, but most participants felt that patients eventually understood the treatment recommendation after informed discussion. Recommendations to enhance the delivery of NT included improved patient education, communication, and better evidence. CONCLUSION In this qualitative study, indications for, barriers to, and opportunities to improve the delivery of NT for localized PDAC were identified. These results highlight the need for better evidence and protocol standardization for NT as well as methods of improving care coordination, communication, and education to improve patient-centered outcomes.

The impact of chemotherapy sequencing on resectable pancreatic cancer by stage. Surg Oncol 2021; 40:101694. [PMID: 34973593 DOI: 10.1016/j.suronc.2021.101694] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 11/30/2021] [Accepted: 12/11/2021] [Indexed: 11/23/2022]
Abstract
INTRODUCTION While chemotherapy is an important therapeutic modality for pancreatic cancer (PDAC), the optimal sequence of chemotherapy to surgery remains unclear. Further, the precise added benefit of including chemotherapy at each (especially early) stage has not been quantified. METHODS The National Cancer Database (NCDB) was queried for patients with PDAC who underwent pancreaticoduodenectomy between 2004 and 2016. Cox multivariable and Kaplan-Meier survival analyses were performed for disease-specific survival (DSS) and overall survival (OS) after correcting for confounders. Permutations of chemotherapy/surgery were compared: preoperative only (NCT), postoperative only (ACT), pre- and post-operative (perioperative, PCT), and no therapy (NoT). RESULTS 22975 patients met inclusion criteria. 13944(61%) received ACT, 1793(8%) received NCT and 946(4%) received PCT, while 6292(27%) did not receive chemotherapy. Log-rank test showed inferior survival in the NoT group compared to NCT, ACT, and PCT. Compared to the NoT group, PCT had the lowest rate of death (HR 0.704, p < 0.001) followed by NCT (HR 0.721, p < 0.001) and ACT (HR 0.759, p < 0.001).). CONCLUSION PDAC patients receiving chemotherapy, independent of their stage, will result in better DSS and OS. NCT should be given consideration for resectable disease including early stage PDAC and ideally complemented with postoperative chemotherapy. While there was a trend towards improved survival for PCT, NCT and ACT are reasonable options for stages IB-III.

Abstract
Adjuvant chemotherapy (ACT) significantly improves survival of patients undergoing upfront surgery for resectable pancreatic cancer. After introducing the concept of neoadjuvant therapy (NAT) with potent chemotherapy regimens, long term survival has been achieved even in patients with borderline and locally advanced pancreatic cancer (BR/LAPC) following radical resection. The observed pathologic tumor response is strongly predictive of survival and provides a unique opportunity to visualize to what extent the cancer has been sensitive to the administered chemotherapy regimen and may potentially give hint how to personalize further oncologic treatment. Current literature provides only limited and heterogeneous data as to whether and what type of ACT is beneficial after NAT and resection for BR/LAPC. Larger studies suggest that ACT may bring survival advantage and should be attempted particularly in node-positive disease and preferably with more potent regimen such as FOLFIRINOX, if tolerable. In case of complete pathologic response, particularly after FOLFIRINOX, it does not seem beneficial to deescalate the treatment during ACT, but whether continuation on the same regimen is worthwhile needs to be further examined. In case of gemcitabine-based treatment as NAT, continuation with more cycles seems to be of value unless tumor biology proves to be too aggressive, with high lymph node ratio. Whether switch to a different regimen should be sought, if tolerability allows it, needs to be further studied. Whether it is the exact treatment sequence (NAT, ACT or both) of the potent chemotherapy regimens like FOLFIRINOX and gemcitabine-nab-paclitaxel or the total dose of chemotherapy that has impact on survival in BR/LAPC, is unknown.

Abstract
BACKGROUND Current treatment of potentially resectable pancreatic ductal adenocarcinoma (PDAC) includes pancreatic resection followed by adjuvant therapy. Aim of this study is to identify factors that are related with overall and early recurrence after pancreatectomy for PDAC. METHODS Retrospective analysis of patients with histologically confirmed PDAC who underwent pancreatectomy between September 2009 and December 2014. Early relapse was defined as recurrence within 12 months after surgery. Univariate/multivariate analysis was performed to identify prognostic factors for recurrence. RESULTS 261 patients were included (54% males, mean age 67 years). Neoadjuvant and adjuvant treatments were performed in 55 (21%) and 243 (93%) patients. Overall morbidity was 56% with a rate of grade 3-4 Clavien-Dindo complications of 25%. Median disease-free survival was 18 months. Multivariate analysis identified nodal metastases (OR: 3.6) and perineural invasion (OR: 2.14) as independent predictors of disease recurrence in the entire cohort. 76 patients (29%) had an early recurrence. Poorly differentiated tumors (OR: 3.019) and grade 3-4 Clavien-Dindo complications (OR: 3.05) were independent risk factors for early recurrence. CONCLUSION Although overall recurrence is associated with tumor-related factors, severe postoperative complications represent an independent predictor of early recurrence. Patients at increased risk of severe postoperative complications may benefit from neoadjuvant therapy.

Abstract
Introduction Radical resection is the only curative treatment for pancreatic cancer, which is a life-threatening disease. However, it is often not easy to accurately identify the extent of the tumor before and during surgery. Here we describe the development of a novel method to detect pancreatic tumors using a tumor-specific enzyme-activatable fluorescence probe. Methods Tumor and non-tumor lysate or small specimen collected from the resected specimen were selected to serve as the most appropriate fluorescence probe to distinguish cancer tissues from noncancerous tissues. The selected probe was sprayed onto the cut surface of the resected specimen of cancer tissue to acquire a fluorescence image. Next, we evaluated the ability of the probe to detect the tumor and calculated the tumor-to-background ratio (TBR) by comparing the fluorescence image with the pathological extent of the tumor. Finally, we searched for a tumor-specific enzyme that optimally activates the selected probe. Results Using a library comprising 309 unique fluorescence probes, we selected GP-HMRG as the most appropriate activatable fluorescence probe. We obtained eight fluorescence images of resected specimens, among which four approximated the pathological findings of the tumor, which achieved the highest TBR. Finally, dipeptidyl-peptidase IV (DPP-IV) or a DPP-IV-like enzyme was identified as the target enzyme. Conclusion This novel method may enable rapid and real-time visualization of pancreatic cancer through the enzymatic activities of cancer tissues.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is one of the malignancies with the worst prognosis despite a decade of efforts. Up to eighty percent of patients are managed at late stages with metastatic disease, in part due to a lack of diagnosis. The effectiveness of PDAC therapies is challenged by the early and widespread metastasis. Epithelial to mesenchymal transition (EMT) is a major driver of cancer progression and metastasis. This process allows cancer cells to gain invasive properties by switching their phenotype from epithelial to mesenchymal. The importance of EMT has been largely described in PDAC, and its importance is notably highlighted by the two major subtypes found in PDAC: the classical epithelial and the quasi-mesenchymal subtypes. Quasi-mesenchymal subtypes have been associated with a poorer prognosis. EMT has also been associated with resistance to treatments such as chemotherapy and immunotherapy. EMT is associated with several key molecular markers both epithelial and mesenchymal. Those markers might be helpful as a biomarker in PDAC diagnosis. EMT might becoming a key new target of interest for the treatment PDAC. In this review, we describe the role of EMT in PDAC, its contribution in diagnosis, in the orientation and treatment follow-up. We also discuss the putative role of EMT as a new therapeutic target in the management of PDAC.

Abstract
BACKGROUND With limited evidence, the benefit of adjuvant chemotherapy (AT) after completion of neoadjuvant chemotherapy (NT) and surgical resection for patients with pancreatic adenocarcinoma is debated. Guidelines recommend 6 months of AT for patients receiving NT. However, the patient-derived benefit from additional AT remains unknown. METHODS The National Cancer Database from 2006 to 2015 was used to identify patients undergoing NT. The chi-square test and multivariable logistic regression were used to identify differences between those receiving only NT and those receiving NT and AT. Survival analysis using the Kaplan-Meier method and the Cox proportional hazard ratio model was applied to the entire cohort and to subgroups with differing lymph node ratios (LNRs), tumor sizes, grades, and surgical margin statuses. RESULTS Of the 3897 patients who received NT, 36.7 % received additional AT. Analysis of the entire cohort showed that associated survival was significantly improved with NT and AT compared with NT alone (hazard ratio [HR], 0.83; p < 0.001). In the subgroup analysis, the survival benefit of additional AT remained significant for those with negative nodal disease, an LNR lower than 0.15, low-grade histology, and negative margin status. Overall survival did not differ between those receiving NT only and those receiving NT and AT in the group with an LNR of 0.15 or higher, high-grade histology, and positive margins. CONCLUSION This study identified an increasing trend in the use of AT after NT and showed an associated survival benefit for subgroups with low-risk pathologic features. These results suggest that the addition of AT after NT likely beneficial for these subgroups.

Abstract
BACKGROUND Despite controversy regarding the role of neoadjuvant chemotherapy (NAC) in pancreatic adenocarcinoma, nearly half of resected patients do not receive chemotherapy postoperatively. This study aimed to examine whether use of NAC compensates for omission of adjuvant chemotherapy (AC) for resected pancreatic adenocarcinoma. METHODS Adults with resected stages 1 to 3 pancreatic adenocarcinoma were enrolled from the National Cancer Database NCDB (2006-2016). Overall survival (OS) analyses were used to examine the impact of NAC on those who did not receive AC. RESULTS The study analyzed a national cohort of 56,286 patients: 30% without chemotherapy, 11% with NAC, 54% with AC, and 5% with NAC plus AC. Use of NAC increased by more than 400% from 2006 to 2016, whereas the rates for omission of chemotherapy remained unchanged. The OS rates were similar between the patients who received NAC and those who received AC (hazard ratio, 0.97; p = 0.21). Among the patients who did not receive AC, NAC was associated with improved OS (26.7 vs. 18.4 months; p < 0.0001). The patients who did not receive AC but underwent NAC had a median OS comparable with the OS of those who received AC alone (26.9 vs. 24.7 months). In the adjusted analysis, the use of NAC for those without AC was significantly associated with improved OS (estimate, - 0.24; p < 0.0001). CONCLUSIONS Although data are limited regarding the survival benefit derived from neoadjuvant versus adjuvant chemotherapy in pancreatic adenocarcinoma, nearly half of patients do not receive adjuvant chemotherapy. This study demonstrates that the use of NAC lessens the survival disadvantage caused by omission of AC. Despite controversy, NAC may be considered for pancreatic adenocarcinoma patients given the high likelihood that adjuvant chemotherapy will be omitted.

Neoadjuvant therapy versus upfront surgery for early-stage left-sided pancreatic adenocarcinoma: A propensity-matched analysis from a national cohort of distal pancreatectomies. J Surg Oncol 2020; 123:245-251.

Abstract
BACKGROUND There are limited data on the efficacy of neoadjuvant therapy (NAT) for early-stage distal pancreas adenocarcinoma (PDAC). Previous studies focused on adenocarcinoma of the head of the pancreas or dealt with borderline and locally advanced tumors of the body and tail. METHODS This is a retrospective study of the National Cancer Database between 2006 and 2015. A propensity-matched analysis was performed to compare overall survival estimates between NAT and upfront resection (UR) groups. RESULTS A total of 5003 distal pancreatectomies for PDAC were identified, of whom 408 (9%) received NAT. After 1:1 matching, 353 NAT patients were compared with 353 UR patients. NAT was associated with lower 90-day mortality. There were no differences in the number of lymph nodes retrieved, or length of stay. With matching, the NAT group had higher median overall survival compared with UR (33.0 vs. 27.0 months; p = 0.009) and adjusted overall survival (hazard ratio = 0.63, 95% confidence interval = 0.51-0.77; p < 0.001). CONCLUSION The receipt of NAT followed by distal pancreatectomy for early-stage distal PDAC is associated with improved overall survival compared with UR. This study supports the use of NAT in the multimodal therapy paradigm of early-stage adenocarcinoma of the body and tail of the pancreas.

Abstract
BACKGROUND The optimal cutoffs for carbohydrate antigen 19-9 (CA19-9) response after neoadjuvant therapy (NT) for pancreatic adenocarcinoma (PDAC) are not well characterized. This study aimed to analyze the relationship of serum CA19-9 to other markers of response and to identify thresholds correlating to outcomes. METHODS A retrospective review of resected PDAC patients from 2010 to 2017 at an academic tertiary referral center was conducted. RESULTS The analysis enrolled 250 subjects. Normalization and multiple cutoff points for CA19-9 response were assessed. Normalization was not associated with improved survival (35.17 vs. 29.43 months; p = 0.173). Although a response 45% or higher was associated with longer survival (35 vs. 20 months; p = 0.018), a response of 85% or higher was optimal (55.7 vs. 25.97 months; p < 0.0001). A response of 85% or higher remained a strong independent predictor of survival [hazard ratio (HR), 0.47; p = 0.007]. Subjects with a response of 85% or higher had received more NT cycles [3 (range 2-6) vs. 3 (range 2-4) cycles; p = 0.006] and fewer adjuvant cycles [4 (range 3-6) vs. 5 (range 3-6) cycles; p = 0.027]. Reduction in T-size correlated with a drop in CA19-9 and a size reduction of 25% or higher (56.97 vs. 28.17 months; p = 0.016) improved survival. A serum CA19-9 response of 85% or higher was a strong independent predictor of a reduction in T-size of 25% or higher (HR 2.40; p = 0.007). CONCLUSION A CA19-9 response of 85% or higher is the optimal threshold for predicting survival. It is predictive of T-size reduction. Future NT trials should incorporate CA19-9 response as an end point.

Abstract
BACKGROUND While combination therapy with nab-paclitaxel/gemcitabine (nab-gem) is effective in pancreatic ductal adenocarcinoma (PDAC), its efficacy as perioperative chemotherapy is unknown. The primary objective of this multicenter, prospective, single-arm, phase II study was to determine whether neoadjuvant therapy with nab-gem was associated with higher complete resection rates (R0) in resectable PDAC, while the secondary objectives were to determine the utility of radiological assessment of response to preoperative chemotherapy and the safety and efficacy of nab-gem as perioperative therapy. METHODS Patients were recruited from eight Australian sites, and 42 patients with radiologically defined resectable PDAC and an Eastern Cooperative Oncology Group performance status of 0-2 were enrolled. Participants received two cycles of preoperative nab-paclitaxel 125 mg/m2 and gemcitabine 1000 mg/m2 on days 1, 8, and 15 (28-day cycle) presurgery, and four cycles postoperatively. Early response to chemotherapy was measured with fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) scans on day 15. RESULTS Preoperative nab-gem was completed by 93% of participants, but only 63% postoperatively. Thirty-six patients had surgery: 6 (17%) were unresectable, 15 (52%) had R0 (≥ 1 mm) resections, 14 (48%) had R1 (< 1 mm) resections, and 1 patient did not have PDAC. Median progression-free survival was 12.3 months and median overall survival (OS) was 23.5 months: R0 patients had an OS of 35 months versus 25.6 months for R1 patients after surgery. Seven patients had not progressed after 43 months. CONCLUSIONS The GAP trial demonstrated that perioperative nab-gem was tolerable. Although the primary endpoint of an 85% R0 rate was not met, the R0 rate was similar to trials using a > 1 mm R0 resection definition, and survival rates were comparable with recent adjuvant studies.

Abstract
Pancreatic cancer is one of the most lethal solid organ tumors. Due to the rising incidence, late diagnosis, and limited treatment options, it is expected to be the second leading cause of cancer deaths in high income countries in the next decade. The multidisciplinary treatment of this disease depends on the stage of cancer at diagnosis (resectable, borderline, locally advanced, and metastatic disease), and combines surgery, chemotherapy, chemoradiotherapy, and supportive care. The landscape of multidisciplinary pancreatic cancer treatment is changing rapidly, especially in locally advanced disease, and the number of treatment options in metastatic disease, including personalized medicine, innovative targets, immunotherapy, therapeutic vaccines, adoptive T-cell transfer, or stemness inhibitors, will probably expand in the near future. This review summarizes the current literature and provides an overview of how new therapies or new therapeutic strategies (neoadjuvant therapies, conversion surgery) will guide multidisciplinary disease management, future clinical trials, and, hopefully, will increase overall survival.

Abstract
Pancreatic cancer is one of the most lethal malignancies and is associated with a poor prognosis. Surgery is considered the only potential curative treatment for pancreatic cancer, followed by adjuvant chemotherapy, but surgery is reserved for the minority of patients with non-metastatic resectable tumors. In the future, neoadjuvant treatment strategies based on molecular testing of tumor biopsies may increase the amount of patients becoming eligible for surgery. In the context of non-metastatic disease, patients with resectable or borderline resectable pancreatic carcinoma might benefit from neoadjuvant chemo- or chemoradiotherapy followed by surgeryPatients with locally advanced or (oligo-/poly-)metastatic tumors presenting significant response to (neoadjuvant) chemotherapy should undergo surgery if R0 resection seems to be achievable. New immunotherapeutic strategies to induce potent immune response to the tumors and investigation in molecular mechanisms driving tumorigenesis of pancreatic cancer may provide novel therapeutic opportunities in patients with pancreatic carcinoma and help patient selection for optimal treatment.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma remains a disease with a poor prognosis despite advances in surgery and systemic therapies. Neoadjuvant therapy strategies are a promising alternative to adjuvant chemotherapy. However, their role remains controversial. This meta-analysis aims to clarify the benefits of neoadjuvant therapy in resectable pancreatic ductal adenocarcinoma. METHODS Eligible studies were identified from MEDLINE, Embase, Web of Science and the Cochrane Library. Studies comparing neoadjuvant therapy with a surgery first approach (with or without adjuvant therapy) in resectable pancreatic ductal adenocarcinoma were included. The primary outcome assessed was overall survival. A random-effects meta-analysis was performed, together with pooling of unadjusted Kaplan-Meier curve data. RESULTS A total of 533 studies were identified that analysed the effect of neoadjuvant therapy in pancreatic ductal adenocarcinoma. Twenty-seven studies were included in the final data synthesis. Meta-analysis suggested beneficial effects of neoadjuvant therapy with prolonged survival compared with a surgery-first approach, (hazard ratio 0.72, 95% confidence interval 0.69-0.76). In addition, R0 resection rates were significantly higher in patients receiving neoadjuvant therapy (relative risk 0.51, 95% confidence interval 0.47-0.55). Individual patient data analysis suggested that overall survival was better for patients receiving neoadjuvant therapy (P = 0.008). CONCLUSIONS Current evidence suggests that neoadjuvant chemotherapy has a beneficial effect on overall survival in resectable pancreatic ductal adenocarcinoma in comparison with upfront surgery and adjuvant therapy. Further trials are needed to address the need for practice change.

Abstract
BACKGROUND Neoadjuvant chemotherapy (NAC) is increasingly utilized to optimize survival in proximal pancreatic adenocarcinoma. However, few studies have explored the impact of NAC in distal pancreas cancer. METHODS Patients with resectable pancreatic adenocarcinoma of the body or tail treated with either upfront pancreatectomy or NAC followed by surgery were identified in the 2006-2014 National Cancer Database. Trends in utilization, predictors of use, and impact of NAC on overall survival were determined. RESULTS Of 1485 patients, 176 (11.9%) received NAC. Use of NAC increased from 9.3% in 2006 to 16.9% in 2013 [odds ratio 1.14; 95% confidence interval (CI) 1.05-1.24; p = 0.001]. NAC patients were younger, had higher clinical stage, and preoperative CA 19-9 levels (all p < 0.05). After adjustment for patient-, tumor-, and treatment-related factors, increased clinical stage was the greatest independent predictor of neoadjuvant approach (p < 0.001). On multivariable analysis, survival benefit from NAC did not reach threshold of significance (95% CI 0.66-1.04; p = 0.10) for the entire cohort. However, NAC was associated with a significant survival advantage in clinical stage III with a 51% decreased yearly risk of death (adjusted hazard ratio 0.49; 95% CI 0.25-0.98; p = 0.04). A trend towards improved survival with NAC was observed among stage IIA (p = 0.09) and IIB (p = 0.07) patients. CONCLUSIONS Neoadjuvant chemotherapy is associated with improved overall survival in Stage III distal pancreatic adenocarcinoma and shows promise in earlier stage disease. However, only a small percentage of patients receive NAC. Prospective evaluation of NAC in distal pancreatic adenocarcinoma is warranted based on these findings.

Abstract
There is controversy regarding the role of neoadjuvant versus adjuvant chemotherapy for pancreatic cancer (PAC). Neoadjuvant therapy has been touted as a method to improve survival in PAC patients. This study's objective is to investigate predictors and potential benefits of neoadjuvant therapy in resectable PAC patients. The National Cancer Data Base was used to retrospectively analyze stage I and II surgically resected PAC patients receiving adjuvant or neoadjuvant therapy from 2004 to 2012. A total of 12,983 patients were identified. A significant increase in the rate of neoadjuvant therapy was observed over time with 5 per cent receiving neoadjuvant therapy in 2004 versus 17 per cent in 2012 (P < 0.0001). Multivariate analysis showed that patients were more likely to receive neoadjuvant therapy if they were treated at an academic facility. Private insurance was associated with higher odds of neoadjuvant chemotherapy (P < 0.0001). Pathological outcomes were improved in neoadjuvant patients compared with adjuvant patients on multivariate analysis with neoadjuvant patients having higher rates of negative surgical margins (OR: 1.273, 95% Confidence interval: 1.099–1.474) and negative lymph nodes (OR: 2.852, 95% Confidence interval: 2.547–3.194). Pathological outcomes are improved after neoadjuvant therapy compared with adjuvant therapy, with more patients achieving negative margins and negative lymph nodes. Prospective studies are needed to compare these two treatment modalities in a head to head comparison.

Abstract
INTRODUCTION Evidence supporting adjuvant therapy for resected pancreatic cancer is limited primarily to head tumors. We analyzed data from the National Cancer Database (NCDB) to evaluate the relationship of tumor site with benefit from adjunctive (adjuvant, neoadjuvant, perioperative) therapy (Rx). METHODS All NCDB patients with clinical stage I and II pancreatic cancer, diagnosed from 2003 to 2013, who underwent surgical resection and had data on site of primary were included. Overall survival (OS) analyses with hazard ratios (HR), 95% confidence intervals (CI), and two-sided p-values are presented. RESULTS A total of 27,930 patients met inclusion criteria; median age 66 years, 51% males, 86% white. Primary site was coded as head (74.4%), body (9.3%), or tail (16.3%). Pathologic stage was predominantly stage II (77%); 81% had negative margins. Perioperative Rx was used in 4%, neoadjuvant in 8%, adjuvant in 48%. Median OS for the cohort was 24 months; for head, body and tail tumors, it was 21.6, 34.5, and 42.5 months, respectively. In univariable analyses, adjunctive Rx was associated with improved OS in head tumors (HR, any Rx vs. no Rx: 0.87; 95% CI 0.84-0.91; p < 0.0001) but not in body (1.82; 1.59-2.08; <0.0001) and tail (2.28; 2.05-2.53; <0.0001) tumors; multivariable models including statistically significant predictors (Charlson-Deyo comorbidity score, tumor grade and stage, positive resection margin) confirmed these results. CONCLUSIONS Our study suggests that the benefit of adjunctive Rx is restricted to pancreatic head tumors; body and tail tumors have a much better prognosis. These results warrant further evaluation in prospective studies.

Abstract
BACKGROUND AND OBJECTIVES Surgery followed by gemcitabine and/or a fluoropyrimidine is standard therapy for resectable PDAC. mFOLFIRINOX (oxaliplatin 85 mg/m2 , irinotecan 180 mg/m2 , leucovorin 400 mg/m2 Day 1, 5-FU 2400 mg/m2 × 48 h IV, peg-filgrastim 6 mg SQ day 3, every 14 days) has substantial activity in metastatic PDAC. We wished to determine the tolerability/efficacy of peri-operative mFOLFIRINOX in resectable PDAC. METHODS Patients with resectable PDAC (ECOG PS 0/1) received four cycles of mFOLFIRINOX pre- and post-surgery. The primary endpoint was completion of preoperative chemotherapy plus resection. Secondary endpoints included completion of all therapy, R0 resection, treatment related toxicity, PFS, and OS. RESULTS Twenty-one patients enrolled: median age 62 (47-78); 20/21 (95%) completed four cycles of preoperative mFOLFIRINOX; response by RECIST was 1 CR, 3 PR, 16 SD; 17/21 (81%) completed resection, 16/21 (76%) R0; 14/21 (66%) completed four cycles of postoperative mFOLFIRINOX. Grade 3 and 4 toxicity occurred in 23% and 14% patients pre-operatively, 26% and 6.0% post-operatively. Nine patients are alive with median follow-up of 27.7 (3.1-47.1) months. CONCLUSIONS PST using mFOLFIRINOX in resectable PDAC is feasible and tolerable. R0 resection rate is high and survival promising, requiring longer follow-up and larger studies for definitive assessment.

Abstract
Local recurrence of pancreatic cancer (PC) can occur in the pancreatic remnant. In addition, new primary PC can develop in the remnant. There are limited data available regarding this so-called remnant PC. The aim of this review was to describe the characteristics and therapeutic strategy regarding remnant PC. A literature search was performed using Medline published in English according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The incidence of remnant PC has been reported to be 3% to 5%. It is difficult to distinguish local recurrence from new primary PC. Genetic diagnosis such as Kirsten rat sarcoma viral oncogene homolog mutation may resolve this problem. For patients with remnant PC, repeated pancreatectomy can be performed. Residual total pancreatectomy is the most common procedure. Recent studies have described the safety of the operation because of recent surgical progress and perioperative care. The patients with remnant PC without distant metastasis have shown good long-term outcomes, especially those who underwent repeated pancreatectomy. Adjuvant chemotherapy may contribute to longer survival. In conclusion, this review found that both local recurrence and new primary PC can develop in the pancreatic remnant. Repeated pancreatectomy for the remnant PC is a feasible procedure and can prolong patient survival.

Abstract
OPINION STATEMENT Pancreatic cancer surgery is a continuously evolving field. Despite tremendous advances in perioperative outcomes, pancreatic resection is still associated with substantial morbidity, and mortality is not nil. Institutional caseload is a well-established determinant of patient outcomes, and centralization to experienced centers is essential to the safety and oncological appropriateness of the resection. Minimally invasive approaches are increasingly applied for pancreatic resection, even in cancer patients. Nevertheless, the level of evidence in this field remains low. Minimally invasive distal pancreatectomy appears potentially beneficial towards some perioperative outcomes, although its oncological results remain incompletely studied. Data regarding perioperative and oncologic outcomes for minimally invasive pancreaticoduodenectomy (Whipple's resection) is even less mature, but suggest that similar results as the open approach can be achieved in selected, high-volume centers. Conversely, its indiscriminate adoption by inexperienced surgeons and institutions has potential deleterious effects given its steep learning curve. Newer neoadjuvant treatment protocols display enhanced ability to downstage advanced tumors, increasing candidates for potentially curative surgery. Conversely, putative benefits of neoadjuvant treatment in patients with technically resectable tumors have not been reliably demonstrated and its optimal indications remain highly controversial.

Abstract
The standard treatment of resectable pancreatic cancer is surgery followed by adjuvant chemotherapy. Due to the complication rate of pancreatic surgery and the high rate of primary irresectability, neoadjuvant concepts are increasingly used for pancreatic cancer. Neoadjuvant therapy is better tolerated than adjuvant and might decrease the surgical complication rate from pancreatic surgery. In contrast to neoadjuvant chemoradiation, the nutritional status improves during neoadjuvant chemotherapy. Also, the survival of patients who develop postoperative complications after neoadjuvant therapy is comparable to those without complications whereas the survival of patients who underwent upfront surgery and then develop surgical complications is impaired. Moreover, large data base analyses suggest a down-sizing effect and improvement of overall survival by neoadjuvant therapy. Neoadjuvant chemotherapy appears to be equally efficient in converting irresectable in resectable disease and more efficient with regard to systemic tumor progression and overall survival compared to neoadjuvant chemoradiation therapy. Despite these convincing findings from mostly small phase II trials, neoadjuvant therapy has not yet proven superiority over upfront surgery in randomized trials.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is a deadly disease. Neoadjuvant therapy (NA) with chemotherapy (NAC) and radiotherapy (RT) prior to surgery provides promise. In the absence of prospective data, well annotated clinical data from high-volume units may provide pilot data for randomised trials. METHODS Medical records from a tertiary hospital in Sydney, Australia, were analysed to identify all patients with resectable or borderline resectable PDAC. Data regarding treatment, toxicity and survival were collected. RESULTS Between January 1 2010 and April 1 2016, 220 sequential patients were treated: 87 with NA and 133 with upfront operation (UO). Forty-three NA patients (52%) and 5 UO patients (4%) were borderline resectable at diagnosis. Twenty-four borderline patients received NA RT, 22 sequential to NAC. The median overall survival (OS) in the NA group was 25.9 months (mo); 95% CI (21.1-43.0 mo) compared to 26.9 mo (19.7, 32.7) in the UO; HR 0.89; log-ranked p-value = 0.58. Sixty-nine NA patients (79%) were resected, mOS was 29.2 mo (22.27, not reached (NR)). Twenty-two NA (31%) versus 22 UO (17%) were node negative at operation (N0). In those managed with NAC/RT the mOS was 29.0 mo (17.3, NR). There were no post-operative deaths with NA within 90-days and three in the UO arm. DISCUSSION This is a hypothesis generating retrospective review of a selected real-world population in a high-throughput unit. Treatment with NA was well tolerated. The long observed survival in this group may be explained by lymph node sterilisation by NA, and the achievement of R0 resection in a greater proportion of patients.

Abstract
Treatment of pancreatic cancer is multimodal and surgery is an essential part, mandatory for curative potential. Also chemotherapy is essential, and serious postoperative complications or rapid disease progression may preclude completion of multimodal treatment. The sequence of treatment interventions has therefore become an important concern, and numerous ongoing randomized controlled trials compare clinical outcome after upfront surgery and neoadjuvant treatment with subsequent resection. In previous years, borderline resectable and locally advanced pancreatic cancer was most often considered unresectable. More effective chemotherapy together with the latest improvements in surgical expertise has resulted in extended operations, pushing the borders of resectability. Multivisceral resections with or without resection of major mesenteric vessels are now performed in numerous patients, resulting in better outcome, recorded as overall survival and/or patient reported outcome. But postoperative morbidity increases concurrently, and clinical benefit must be carefully evaluated against risk of potential harm, associated with new comprehensive multimodal treatment sequences. Even though cost/utility analyses are deficient, extended surgery has resulted in significantly longer and better life for many patients with no other treatment alternative. Improved selection of patients to surgery and/or chemotherapy will in the near future be possible, based on better tumor biology insight. Clinically available biomarkers enabling personalized treatment are forthcoming, but these options are still limited. The importance of surgical resection for each patient’s prognosis is presently increasing, justifying sustained expansion of the surgical treatment modality.

Abstract
Pancreatic cancer is a growing problem in oncology, given slowly rising incidence and continued suboptimal outcomes. A concerted effort to reverse this tide will require prevention, early diagnosis, and improved systemic therapy for curable disease. We focus on these aspects in detail in this study. Hereditary pancreatic cancer is an underappreciated area. With the growing use of genomics (both somatic and germline) in cancer care, there is increasing recognition of hereditary pancreatic cancer cases: around 10% of all pancreatic cancer may be related to familial syndromes, such as familial atypical multiple mole and melanoma (FAMMM) syndrome, hereditary breast and ovarian cancer, Lynch syndrome, and Peutz-Jeghers syndrome. Screening and surveillance guidelines by various expert groups are discussed. Management of resectable pancreatic cancer is evolving; the use of multiagent systemic therapies, in the adjuvant and neoadjuvant settings, is discussed. Current and emerging data, along with ongoing clinical trials addressing important questions in this area, are described. Surveillance recommendations based on latest ASCO guidelines are also discussed. Finally, the multimodality management of borderline resectable pancreatic cancer is discussed. The various clinicoanatomic definitions of this entity, followed by consensus definitions, are described. Then, we focus on current opinions and practices around neoadjuvant therapy, discussing chemotherapy and radiation aspects, and the role of surgical resection.

Abstract
Chemotherapy with improved effect in patients with metastatic pancreatic cancer has recently been established, launching a new era for patients with this very aggressive disease. FOLFIRINOX and gemcitabine plus nab-paclitaxel are different regimens, both capable of stabilizing the disease, thus increasing the number of patients who can reach second line and even third line of treatment. Concurrently, new windows of opportunity open for nutritional support and other therapeutic interventions, improving quality of life. Also pancreatic surgery has changed significantly during the latest years. Extended operations, including vascular/multivisceral resections are frequently performed in specialized centers, pushing borders of resectability. Potentially curative treatment including neoadjuvant and adjuvant chemotherapy is offered new patient groups. Translational research is the basis for the essential understanding of the ongoing development. Even thou biomarkers for clinical management of patients with periampullary tumors have almost been lacking, biomarker driven trials are now in progress. New insight is constantly made available for clinicians; one recent example is selection of patients for gemcitabine treatment based on the expression level of the human equilibrium nucleoside transporter 1. An example of new diagnostic tools is identification of early pancreatic cancer patients by a three-biomarker panel in urine: The proteins lymphatic vessel endothelial hyaluronan receptor 1, regenerating gene 1 alpha and translation elongation factor 1 alpha. Requirement of treatment guideline revisions is intensifying, as combined chemotherapy regimens result in unexpected advantages. The European Study Group for Pancreatic Cancer 4 trial outcome is an illustration: Addition of capecitabine in the adjuvant setting improved overall survival more than expected from the effect in advanced disease. Rapid implementation of new treatment options is mandatory when progress finally extends to patients with this serious disease.
