Abstract
For patients with locoregionally confined pancreatic ductal adenocarcinoma (PDAC), margin-negative surgical resection is the only known curative treatment; however, the majority of patients are not operable candidates at initial diagnosis. Among patients with resectable disease who undergo surgery alone, the 5-year survival remains poor. Adjuvant therapies, including systemic therapy or chemoradiation, are utilized as they improve locoregional control and overall survival. There has been increasing interest in the use of neoadjuvant therapy to obtain early control of occult metastatic disease, allow local tumor response to facilitate margin-negative resection, and provide a test of time and biology to assist with the selection of candidates most likely to benefit from radical surgical resection. However, limited guidance exists regarding the relative effectiveness of treatment options. In this systematic review, the American Radium Society multidisciplinary gastrointestinal expert panel convened to develop Appropriate Use Criteria evaluating the evidence regarding neoadjuvant treatment for patients with PDAC, including surgery, systemic therapy, and radiotherapy, in terms of oncologic outcomes and quality of life. The evidence was assessed using the Population, Intervention, Comparator, Outcome, and Study (PICOS) design framework and "Preferred Reporting Items for Systematic Reviews and Meta-analyses" 2020 methodology. Eligible studies included phases 2 to 3 trials, meta-analyses, and retrospective analyses published between January 1, 2012 and December 30, 2022 in the Ovid Medline database. A summary of recommendations based on the available literature is outlined to guide practitioners in the management of patients with PDAC.

Abstract
BACKGROUND Seminal trials have demonstrated improved survival in pancreatic adenocarcinoma with novel multiagent chemotherapy regimens. To understand the clinical ramifications of this paradigm shift, we reviewed our institutional experience. METHODS This retrospective cohort study utilized a prospective database at a single institution to study all patients diagnosed with and treated for pancreatic adenocarcinoma between 2000 and 2020. RESULTS 1,572 patients were included of which 36% were diagnosed before (Era 1) and 64% after (Era 2) 2011. Survival improved in Era 2 (Median survival 10 vs 8 months, HR .79; P < .001). The survival advantage for Era 2 was primarily seen in patients with high-risk disease (12 vs10 months, HR .71; P < .001). A similar trend was noted for patients undergoing surgical resection (26 vs 21 months, HR .80; P = .081) and with imminently resectable tumors (19 vs 15 months, HR .88; P = .4); however, this was not statistically significant. There was no survival advantage for patients with stage IV disease (4 vs 4 months). Patients in Era 2 were more likely to undergo surgery (OR 2.78; CI 2.00-3.92, P < .001). This increase was driven primarily by increased surgical resection for those with high-risk disease (42 vs 20%, OR 3.74; P < .001). DISCUSSION/CONCLUSIONS This single institutional study showed improved survival after the shift to novel chemotherapy regimens. This was driven by improved survival for patients with high-risk disease and may be due to more effective eradication of microscopic metastatic disease with adjuvant chemotherapy and increased resection rates.

Abstract
BACKGROUND Patients with resectable and borderline resectable pancreatic ductal adenocarcinoma increasingly receive neoadjuvant therapy prior to surgery. However, the effect of neoadjuvant therapy on the immune microenvironment remains largely unknown. We analyzed the immune microenvironment in pancreatic cancer tumor tissue samples from patients treated with neoadjuvant therapy compared to patients after upfront surgery to gain knowledge about the immunological environment after therapy. METHODS Multispectral imaging was performed on tissue from resected specimens from patients with PDAC who underwent upfront surgery (n = 10), neoadjuvant FOLFIRINOX (n = 10) or gemcitabine + radiotherapy (gem-RT) (n = 9) followed by surgery. The samples were selected by a dedicated pancreas pathologist from both the central part and the invasive front of the tumor (by the resected vein or venous surface) and subsequently analyzed using the Vectra Polaris. RESULTS Patients receiving neoadjuvant FOLFIRINOX display a more pro-inflammatory immune profile, with less regulatory T cells and more CD8 T cells in the tumor tissue compared to patients receiving neoadjuvant gem-RTgem-RT or undergoing upfront surgery. Furthermore, CD163+ macrophages were decreased, and a higher CD163- macrophages versus CD163+ macrophages ratio was found in patients with neoadjuvant FOLFIRINOX. In all treatment groups, percentage of FoxP3+ B cells was significantly higher in tumor tissue compared to adjacent tissue. Furthermore, an increase in regulatory T cells in the tumor tissue was found in patients undergoing upfront surgery or receiving neoadjuvant gem-RT. In the gem-RT group, less CD8 T cells and a higher CD163+ macrophages to CD8 ratio were noted in the tumor tissue, suggesting a more immune suppressive profile in the tumor tissue. CONCLUSION Patients receiving neoadjuvant FOLFIRINOX display a more pro-inflammatory immune profile compared to patients receiving neoadjuvant gem-RT or undergoing upfront surgery. Furthermore, in all treatment groups, a more immune suppressive microenvironment was found in the tumor tissue compared to the adjacent non-tumorous tissue.

Abstract
The molecular dynamics of pancreatic ductal adenocarcinoma (PDAC) under chemotherapy remain incompletely understood. The widespread use of neoadjuvant chemotherapy (NAC) provides a unique opportunity to investigate PDAC samples post-chemotherapy. Leveraging a cohort from Fudan University Shanghai Cancer Center, encompassing PDAC samples with and without exposure to neoadjuvant albumin-bound paclitaxel and gemcitabine (AG), we have compiled data from single-cell and spatial transcriptomes, proteomes, bulk transcriptomes, and metabolomes, deepening our comprehension of the molecular changes in PDACs in response to chemotherapy. Metabolic flux analysis reveals that NAC induces a reprogramming of PDAC metabolic patterns and enhances immunogenicity. Notably, NAC leads to the downregulation of glycolysis and the upregulation of CD36. Tissue microarray analysis demonstrates that high CD36 expression is linked to poorer survival in patients receiving postoperative AG. Targeting CD36 synergistically improves the PDAC response to AG both in vitro and in vivo, including patient-derived preclinical models.

Abstract
Surgery is the only curative treatment for non-metastatic pancreatic adenocarcinoma, but less than 20% of patients present a resectable disease at diagnosis. Treatment strategies and disease definition for borderline resectable pancreatic cancer (BRPC) and locally advanced pancreatic cancer (LAPC) vary in the different cancer centres. Preoperative chemotherapy (CT) is the standard of care for both BRPC and LAPC patients, however literature data are still controversial concerning the type, dose and duration of the different CT regimens, as well as regarding the integration of radiotherapy (RT) or chemoradiation (CRT) in the therapeutic algorithm. In this unsettled debate, we aimed at focusing on the therapeutic regimens currently in use and relative literature data, to report international trials comparing the available therapeutic options or explore the introduction of new pharmacological agents, and to analyse possible new scenarios in microenvironment evaluation before and after neoadjuvant therapies or in patients' selection at a molecular level.

Abstract
INTRODUCTION Over the last decade, a paradigm shift has been made in treating pancreatic cancer. Starting in 2011, several trials demonstrated a survival advantage for multiagent chemotherapy (MAC). However, the implication for survival at the population level remains unclear. METHODS A retrospective study of the National Cancer Database from 2006 to 2019 was conducted. Patients treated from 2006 to 2010 were classified as "Era 1", and those treated from 2011 to 2019 as "Era 2." RESULTS A total of 316,393 patients with pancreatic adenocarcinoma were identified, with 87,742 treated in Era 1 and 228,651 in Era 2. Survival increased from Era 1 to Era 2 in all patients and sub-analyses; surgical (18.7 vs 24.6 months, HR .85, 95% CI 0.82-.88, P < .001), imminently resectable (Stage IA and IB, 12.2 vs 14.8 months, HR .90, 95% CI 0.86-.95, P < .001), high-risk (Stage IIA, IIB, and III, 9.6 vs 11.6 months, HR .82, 95% CI 0.79-.85, P < .001), and Stage IV (3.5 vs 3.9 months, HR .86, 95% CI 0.84-.89, P < .001). Survival was decreased for those who were African American (P = .031), on Medicaid (P < .001), or in the lowest quartile of annual income (P < .001). Surgery rates decreased from 20.5% in Era 1 to 19.8% in Era 2 (P < .001). DISCUSSION Adoption of MAC regimens at a population level correlates with improved pancreatic cancer survival. Unfortunately, socioeconomic factors are associated with an unequal benefit from new treatment regimens, and underuse of surgery for resectable neoplasms persists.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is an aggressive and lethal malignancy with a high rate of recurrence and a dismal 5-year survival rate. Contributing to the poor prognosis of PDAC is the lack of early detection, a complex network of signaling pathways and molecular mechanisms, a dense and desmoplastic stroma, and an immunosuppressive tumor microenvironment. A recent shift toward a neoadjuvant approach to treating PDAC has been sparked by the numerous benefits neoadjuvant therapy (NAT) has to offer compared with upfront surgery. However, certain aspects of NAT against PDAC, including the optimal regimen, the use of radiotherapy, and the selection of patients that would benefit from NAT, have yet to be fully elucidated. This review describes the major signaling pathways and molecular mechanisms involved in PDAC initiation and progression in addition to the immunosuppressive tumor microenvironment of PDAC. We then review current guidelines, ongoing research, and future research directions on the use of NAT based on randomized clinical trials and other studies. Finally, the current use of and research regarding targeted therapy for PDAC are examined. This review bridges the molecular understanding of PDAC with its clinical significance, development of novel therapies, and shifting directions in treatment paradigm.

Abstract
Pancreatic cancer has traditionally been associated with a dismal prognosis, even in early stages of the disease. In recent years, the introduction of newer generation chemotherapy regimens in the adjuvant setting has improved the survival of patients treated with upfront resection. However, there are multiple theoretical advantages to deliver early systemic therapy in patients with localized pancreatic cancer. So far, the evidence supports the use of neoadjuvant therapy for patients with borderline resectable pancreatic cancer. The benefit of this treatment sequence for patients with resectable disease remains elusive. In this review, we summarize the data on adjuvant therapy for pancreatic cancer and describe which evidence backs the use of neoadjuvant therapy. Additionally, we address important issues faced in clinical practice when treating patients with localized pancreatic cancer.
