Abstract
In the context of pancreatic cancer, surgical intervention is typically recommended for localized tumours, whereas chemotherapy is the preferred approach in the advanced and/or metastatic setting. However, pancreatic cancer is closely linked to ageing, with an average diagnosis at 72 years. Paradoxically, despite its increased occurrence among older individuals, this population is often underrepresented in clinical studies, complicating the decision-making process. Age alone should not determine the therapeutic strategy but, given the high comorbidity and mortality of this disease, a comprehensive geriatric assessment (CGA) is necessary to define the best treatment, prevent toxicity, and optimize older patient care. In this review, a group of experts from the Oncogeriatrics Section of the Spanish Society of Medical Oncology (Sociedad Española de Oncología Médica, SEOM), the Spanish Cooperative Group for the Treatment of Digestive Tumours (Grupo Español de Tratamiento de los Tumores Digestivos, TTD), and the Multidisciplinary Spanish Group of Digestive Cancer (Grupo Español Multidisciplinar en Cáncer Digestivo, GEMCAD) have assessed the available scientific evidence and propose a series of recommendations on the management and treatment of the older population with pancreatic cancer.

Abstract
Despite the advancements in the treatment of localized pancreatic cancer, several unresolved issues persist in clinical practice, especially in the neoadjuvant setting. These include determining the criteria for selecting patients for treatment, identifying the most effective chemotherapy regimens, understanding the role of radiotherapy, and accurately assessing how patients respond to treatment. Current strategies for assessing patients before surgery involve thoroughly evaluating their overall health status, analyzing tumor markers, and using advanced imaging techniques. However, existing methods for staging the disease still have limitations when it comes to accurately detecting metastatic cancer. The ongoing debate between performing surgery upfront or administering neoadjuvant therapy highlights the need for robust clinical evidence to guide treatment decisions effectively. This review analyzes the evidence regarding controversial topics in neoadjuvant pancreatic cancer treatment and discusses further research efforts to enhance patient outcomes. To improve the outcomes found with surgery alone, multimodal treatment with chemotherapy.

Radiother Oncol 2024; 191:110059. [PMID: 38135186 DOI: 10.1016/j.radonc.2023.110059] [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: 07/31/2023] [Revised: 12/12/2023] [Accepted: 12/15/2023] [Indexed: 12/24/2023]
Abstract
BACKGROUND AND PURPOSE Due to the high intrinsic radioresistance of pancreatic ductal adenocarcinoma (PDAC), radiotherapy (RT) is only beneficial in 30% of patients. Therefore, this study aimed to identify targets to improve the efficacy of RT in PDAC. MATERIALS AND METHODS Alamar Blue proliferation and colony formation assay (CFA) were used to determine the radioresponse of a cohort of 38 murine PDAC cell lines. A gene set enrichment analysis was performed to reveal differentially expressed pathways. CFA, cell cycle distribution, γH2AX FACS analysis, and Caspase 3/7 SYTOX assay were used to examine the effect of a combination treatment using KIRA8 as an IRE1α-inhibitor and Ceapin-A7 as an inhibitor against ATF6. RESULTS The unfolded protein response (UPR) was identified as a pathway highly expressed in radioresistant cell lines. Using the IRE1α-inhibitor KIRA8 or the ATF6-inhibitor Ceapin-A7 in combination with radiation, a radiosensitizing effect was observed in radioresistant cell lines, but no substantial alteration of the radioresponse in radiosensitive cell lines. Mechanistically, increased apoptosis by KIRA8 in combination with radiation and a cell cycle arrest in the G1 phase after ATF6 inhibition and radiation have been observed in radioresistant cell lines. CONCLUSION So, our data show evidence that the UPR is involved in radioresistance of PDAC. Increased apoptosis and a G1 cell cycle arrest seem to be responsible for the radiosensitizing effect of UPR inhibition. These findings are supportive for developing novel combination treatment concepts in PDAC to overcome radioresistance.

Abstract
Neoadjuvant therapy (NAT) for pancreatic cancer (PC) has achieved certain results. This article was aimed to analyze the trends in NAT in PC over the past 20 years using bibliometric analysis and visualization tools to guide researchers in exploring future research hotspots. Articles related to NAT for PC were retrieved from the Web of Science Core Collection for the period 2002-2021. The information was analyzed and visualized using VOSviewer, Citespace, Microsoft Excel and R software. The number of articles per year has continued to increase over the past 20 years. Of the 1,598 eligible articles, the highest number was from the United States (760), and an analysis of institutions indicated that the University of Texas System (150) had the highest number of articles. Matthew H. G. Katz had the highest number of citations and the highest H-index. "Pancreatic cancer" (981), "Resection" (623), "Cancer" (553), "Neoadjuvant therapy" (509) and "Survival" (484) were the top five ranked keywords. Combined with the keywords-cluster analysis and citation burst analysis, current research hotspots were the optimal NAT regimen, NAT response assessment, NAT for resectable PC and management of complications. NAT has received increasing attention in the field of PC over the past 20 years, but greater collaboration between countries and additional multicenter randomized clinical trials are needed. Overall, we have revealed current research hotspots and provided valuable information for the choice of future research directions.

Abstract
OBJECTIVE To investigate the prognostic value of preoperative neoadjuvant therapy (NT) compared to upfront surgery (US) in patients with resectable and borderline resectable pancreatic cancer. METHODS PubMed, Embase, Web of Science were searched to collect randomized controlled trials on preoperative neoadjuvant therapy versus upfront surgery for resectable and borderline resectable pancreatic cancer before April 7, 2023, and data were extracted after screening according to inclusion and exclusion criteria, and HRs were obtained indirectly using enguage software; Stata 12.0 software was used for data analysis. RESULTS A total of 8 randomized controlled trials (RCTs) were included in this study, comprising a total of 1058 cases, including 503 cases in the NT group and 555 cases in the US group. Using an intention-to-treat population (ITT) analysis, the results showed that neoadjuvant treatment improved the R0 resection rate (RR 2.71, 95% CI 1.59-4.62; P = 0.000; I2 = 46.20%) and overall survival (HR 0.66, 95% CI 0.54-0.82; P = 0.000; I2 = 0.00%). In the subgroup of patients with resectable pancreatic cancer, the R0 resection rate in the NT group versus the US group (RR 1.14, 95% CI 0.93-1.39; P = 0.196; I2 = 0.00%) and overall survival (HR 0.89, 95% CI 0.64-1.24; P = 0.489; I2 = 0.00%) were not statistically significant. CONCLUSIONS Preoperative neoadjuvant treatment is of prognostic value in patients with borderline resectable pancreatic cancer, as it increases the R0 resection rate and improves overall survival compared to upfront surgery.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is a challenging disease process with a 5-year survival rate of only 11%. Neoadjuvant therapy in patients with localized pancreatic cancer has multiple theoretical benefits, including improved patient selection for surgery, early delivery of systemic therapy, and assessment of response to therapy. Herein, we review key surgical considerations when selecting patients for neoadjuvant therapy and curative-intent resection. Accurate determination of resectability at diagnosis is critical and should be based on not only anatomic criteria but also biologic and clinical criteria to determine optimal treatment sequencing. Borderline resectable or locally advanced pancreatic cancer is best treated with neoadjuvant therapy and resection, including vascular resection and reconstruction when appropriate. Lastly, providing nutritional, prehabilitation, and supportive care interventions to improve patient fitness prior to surgical intervention and adequately address the adverse effects of therapy is critical.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest solid malignancies, with a five-year survival of less than 10%. The resistance of the disease and the associated lack of therapeutic response is attributed primarily to its dense, fibrotic stroma, which acts as a barrier to drug perfusion and permits tumour survival and invasion. As clinical trials of chemotherapy (CT), radiotherapy (RT), and targeted agents have not been successful, improving the survival rate in unresectable PDAC remains an urgent clinical need. Photodynamic stromal depletion (PSD) is a recent approach that uses visible or near-infrared light to destroy the desmoplastic tissue. Preclinical evidence suggests this can resensitise tumour cells to subsequent therapies whilst averting the tumorigenic effects of tumour-stromal cell interactions. So far, the pre-clinical studies have suggested that PDT can successfully mediate the destruction of various stromal elements without increasing the aggressiveness of the tumour. However, the complexity of this interplay, including the combined tumour promoting and suppressing effects, poses unknowns for the clinical application of photodynamic stromal depletion in PDAC.

Abstract
Borderline resectable pancreatic cancer (BRPC) is a complex clinical entity with specific biological features. Criteria for resectability need to be assessed in combination with tumor anatomy and oncology. Neoadjuvant therapy (NAT) for BRPC patients is associated with additional survival benefits. Research is currently focused on exploring the optimal NAT regimen and more reliable ways of assessing response to NAT. More attention to management standards during NAT, including biliary drainage and nutritional support, is needed. Surgery remains the cornerstone of BRPC treatment and multidisciplinary teams can help to evaluate whether patients are suitable for surgery and provide individualized management during the perioperative period, including NAT responsiveness and the selection of surgical timing.

Abstract
Backgrounds/Aims To analyze the results of the neoadjuvant treatment of patients in our center with early pancreatic cancer. Methods Eighty-four patients with early pancreatic cancer (I-II) were included, of which 59 were considered "bioborderline" (carbohydrate antigen [CA] 19-9 > 37 U/L), and 25 were considered "non-bioborderline" (CA19-9 < 37 U/L). The R0 resection rate, presence of negative nodes, survival, and recurrence rates were analyzed in two groups, the NEO group (neoadjuvant + surgery) and the non-NEO group (upfront surgery). Results A 28.6% pathologic complete response was observed in the NEO group of the whole sample. The residual R0 was 85.7%, and nodes were negative in 78.6% of the patients in the NEO group of bioborderline patients. All non-bioborderline patients treated with neoadjuvant were R0, and no affected nodes were observed in any of them. The median overall survival (OS) in patients with elevated CA19-9 levels in the NEO group was 31.4 months vs. 13.1 months in the non-NEO (log-rank test p = 0.006), with a 62% relative reduction in the mortality rate (hazard ratio = 0.38, 95% confidence interval: 0.20-0.79; p = 0.008). The median OS in patients with normal CA19-9 levels in the NEO group was 65.9 months vs. 16.2 months in the non-NEO group, without statistically significant differences between the two but with a trend toward significance (log-rank test p = 0.08). Conclusions A neoadjuvant strategy seemed to improve local control and the survival of patients with early pancreatic cancer, both those with elevated CA19-9 and normal marker levels.

Abstract
Currently, 15 randomized controlled trials (RCTs) have been designed to investigate whether neoadjuvant therapy (NAT) benefits patients with resectable pancreatic adenocarcinoma (R-PA) compared to surgery alone. Five of them have acquired results so far; however, corresponding conclusions have not been obtained. We speculated that the reason for this phenomenon could be that some prognostic factors had proven to be adverse through upfront surgery curative patterns, but some of them were not regarded as independent baseline characteristics, which is important to obtaining comparability between the NAT and upfront surgery groups. This fact could cause bias and lead to the difference in the outcomes of RCTs. In this review, we collate data about risk factors (such as tumor size, resection margin, and lymph node status) influencing the prognoses of patients with R-PA from five RCTs and discuss the possible reasons for the varying outcomes.

Abstract
Pancreatic cancer is the fourth leading cause of cancer-related death and the second gastrointestinal cancer-related death in the United States. Early detection and accurate diagnosis and staging of pancreatic cancer are paramount in guiding treatment plans, as surgical resection can provide the only potential cure for this disease. The overall prognosis of pancreatic cancer is poor even in patients with resectable disease. The 5-year survival after surgical resection is ~10% in node-positive disease compared to ~30% in node-negative disease. The advancement of imaging studies and the multidisciplinary approach involving radiologists, gastroenterologists, advanced endoscopists, medical, radiation, and surgical oncologists have a major impact on the management of pancreatic cancer. Endoscopic ultrasonography is essential in the diagnosis by obtaining tissue (FNA or FNB) and in the loco-regional staging of the disease. The advancement in EUS techniques has made this modality a critical adjunct in the management process of pancreatic cancer. In this review article, we provide an overall description of the role of endoscopic ultrasonography in the diagnosis and staging of pancreatic cancer.

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

Abstract
Despite the overall poor prognosis of pancreatic cancer there is heterogeneity in clinical courses of tumors not assessed by conventional risk stratification. This yields the need of additional markers for proper assessment of prognosis and multimodal clinical management. We provide a proof of concept study evaluating the feasibility of Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) to identify specific peptide signatures linked to prognostic parameters of pancreatic cancer. On 18 patients with exocrine pancreatic cancer after tumor resection, MALDI imaging analysis was performed additional to histopathological assessment. Principal component analysis (PCA) was used to explore discrimination of peptide signatures of prognostic histopathological features and receiver operator characteristic (ROC) to identify which specific m/z values are the most discriminative between the prognostic subgroups of patients. Out of 557 aligned m/z values discriminate peptide signatures for the prognostic histopathological features lymphatic vessel invasion (pL, 16 m/z values, eight proteins), nodal metastasis (pN, two m/z values, one protein) and angioinvasion (pV, 4 m/z values, two proteins) were identified. These results yield proof of concept that MALDI-MSI of pancreatic cancer tissue is feasible to identify peptide signatures of prognostic relevance and can augment risk assessment.

Abstract
BACKGROUND Vein resection pancreatoduodenectomy (VRPD) may be performed in selected pancreatic cancer patients. However, the main risks and benefits related to VRPD remain controversial. OBJECTIVE This review aimed to evaluate the risks and survival benefits that the VRPD may add when compared with standard pancreatoduodenectomy (PD). METHODS A systematic review and meta-analysis of studies comparing VRPD and PD were performed. RESULTS VRPD was associated with a higher risk for postoperative mortality (risk difference: -0.01; 95% confidence interval [CI] -0.02 to -0.00) and complications (risk difference: -0.05; 95% CI -0.09 to -0.01) than PD. The length of hospital stay was not different between the groups (mean difference [MD]: -0.65; 95% CI -2.11 to 0.81). In the VRPD, the operating time was 69 minutes higher on average (MD: -69.09; 95% CI -88.4 to -49.78), with a higher blood loss rate (MD: -314.04; 95% CI -423.86 to -195.22). In the overall survival evaluation, the hazard ratio for mortality during follow-up on the group of VRPD was higher compared to the PD group (hazard ratio: 1.13; 95% CI 1.03-1.23). CONCLUSION VRPD is associated with a higher risk of short-term complications and mortality and a lower probability of survival than PD. Knowing the risks and potential benefits of surgery can help clinicians to properly manage pancreatic cancer patients with venous invasion. The decision for surgery with major venous resection should be shared with the patients after they are informed of the risks and prognosis.

Abstract
Purpose Malnutrition is a common problem among pancreatic cancer (PC) patients that negatively impacts on their quality of life (QoL) and clinical outcomes. The main objective of this consensus is to address the role of Medical Nutrition Therapy (MNT) into the comprehensive therapeutic management of PC patients. Methods A Spanish multidisciplinary group of specialists from the areas of Medical Oncology; Radiation Oncology; Endocrinology and Nutrition; and General Surgery agreed to assess the role of MNT as part of the best therapeutic management of PC patients. Results The panel established different recommendations focused on nutritional screening and nutritional screening tools, MNT strategies according to PC status, and MNT in palliative treatment. Conclusions There is an unmet need to integrate nutritional therapy as a crucial part of the multimodal care process in PC patients. Health authorities, health care professionals, cancer patients, and their families should be aware of the relevance of nutritional status and MNT on clinical outcomes and QoL of PC patients.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy that is best treated in a multidisciplinary fashion using surgery, chemotherapy, and radiation. Adjuvant chemotherapy has shown to have a significant survival benefit in patients with resected PDAC. However, up to 50% of patients fail to receive adjuvant chemotherapy due to postoperative complications, poor patient performance status or early disease progression. In order to ensure the delivery of chemotherapy, an alternative strategy is to administer systemic treatment prior to surgery. Precision oncology refers to the application of diverse strategies to target therapies specific to characteristics of a patient’s cancer. While traditionally emphasized in selecting targeted therapies based on molecular, genetic, and radiographic biomarkers for patients with metastatic disease, the neoadjuvant setting is a prime opportunity to utilize personalized approaches. In this article, we describe the current evidence for the use of neoadjuvant therapy (NT) and highlight unique opportunities for personalized care in patients with PDAC undergoing NT.

Abstract
In the last two decades, pancreatic cancer has been undergoing important changes in its perioperative management due to the great interest in multidisciplinary management and preoperative multimodal therapy, which in numerous studies have shown promising clinical results. Although the standard of treatment for resectable pancreatic ductal adenocarcinoma (PDAC) today is surgery followed by adjuvant therapy, as it is a biologically aggressive disease, even with complete resection, it has high rates of local and distant relapse. Several retrospective and prospective phase I/II studies have opened the window for neoadjuvant therapy with chemotherapy (CT), chemoradiotherapy (CRT), or both, as an alternative treatment for resectable pancreatic cancer, with promising results. Neoadjuvant therapy could has some advantages, including early administration of systemic treatment, in vivo assessment of response to treatment, increase resectability rate in borderline patients, increase resection rate with negative margin and survival benefit. While it seems clear that even potentially resectable disease would benefit from preoperative multimodal therapy, the optimal neoadjuvant therapeutic strategy is still controversial and currently there are only recommendations for neoadjuvant treatment, in clinical guidelines such as the NCCN and ESMO, for borderline and/or locally advanced PDAC. This review provides an overview of recent studies available and how they relate to systemic treatment of resectable PDAC in the neoadjuvant setting.

Abstract
BACKGROUND Neoadjuvant therapy is associated with nodal downstaging and improved oncological outcomes in patients with lymph node (LN)-positive pancreatic cancer. This study aimed to develop and validate a nomogram to preoperatively predict LN-positive disease. METHODS A total of 558 patients with resected pancreatic cancer were randomly and equally divided into development and internal validation cohorts. Multivariate logistic regression analysis was used to construct the nomogram. Model performance was evaluated by discrimination, calibration, and clinical usefulness. An independent multicenter cohort consisting of 250 patients was used for external validation. RESULTS A four-marker signature was built consisting of carbohydrate antigen 19-9 (CA19-9), CA125, CA50, and CA242. A nomogram was constructed to predict LN metastasis using three predictors identified by multivariate analysis: risk score of the four-marker signature, computed tomography-reported LN status, and clinical tumor stage. The prediction model exhibited good discrimination ability, with C-indexes of 0.806, 0.742 and 0.763 for the development, internal validation, and external validation cohorts, respectively. The model also showed good calibration and clinical usefulness. A cut-off value (0.72) for the probability of LN metastasis was determined to separate low-risk and high-risk patients. Kaplan-Meier survival analysis revealed a good agreement of the survival curves between the nomogram-predicted status and the true LN status. CONCLUSIONS This nomogram enables the identification of pancreatic cancer patients at high risk for LN positivity who may have more advanced disease and thus could potentially benefit from neoadjuvant therapy.

Abstract
BACKGROUND Solid pseudopapillary neoplasm (SPN) is a rare tumor that was first described by Frantz in 1959. Although this tumor is benign, some may have malignant potential that can be predicted based on demographics, imaging characteristics, and pathologic evaluation. This case series presents 3 SPN cases with discussion on gender differences, preoperative predictors of malignancy, and a suggested algorithm for diagnostic approach as well as post-surgical follow up.
CASE SUMMARY Three adult patients in a tertiary hospital found to have SPN, one elderly male and two young females. Each of the cases presented with abdominal pain and were discovered incidentally. Two cases underwent endoscopic ultrasound with fine needle aspiration and biopsy to assess tumor markers and immuno-histochemical staining (which were consistent with SPN before undergoing surgery), and one case underwent surgery directly after imaging. The average tumor size was 5 cm. Diagnosis was confirmed by histology. Two patients had post-surgical complications requiring intervention.
CONCLUSION Demographic and imaging characteristics can be sufficient to establish diagnosis for SPN, while malignant cases require pre-operative evaluation with endoscopic ultrasound fine needle aspiration/fine needle biopsy.

Abstract
Background We sought to examine the impact of neoadjuvant chemotherapy (NCT), single agent (SA) or multi-agent (MA) chemotherapy, and chemoradiation (NCRT) on response and survival in pancreatic cancer. Methods Utilizing the National Cancer Database, we identified patients who underwent resection of the pancreatic head for adenocarcinoma [2006-2013]. Overall survival (OS) analysis was performed using the Kaplan-Meier method. Multivariable cox proportional hazard models (MVA) and propensity score matching (PSM) were developed to identify predictors of survival. For upfront surgery (UFS), OS was limited to receipt of adjuvant treatment. Results We identified 26,563 patients who underwent pancreatic head resection: UFS =23,877, NCRT =1,482, and NCT =1,204. MA-NCT was utilized in 77% and after PSM, 52%. There was improved R0 resections and 30-day mortality associated with neoadjuvant therapy compared to UFS. Overall response rate to neoadjuvant therapy was 24%. The highest response rate seen with MA-NCRT. Response rates for SA-NCT, MA-NCT, SA-NCRT, and MA-NCRT were 11.5%, 18.1%, 27.5%, and 33.1% (P=0.01). However, OS was improved with neoadjuvant therapy regardless of response compared to UFS (P=0.03). After PSM, the median OS for UFS, SA-NCT, MA-NCT, SA-NCRT, and MA-NCRT was 21.9, 21.5, 29.8, 25.3, and 25.8 months in all patients (P=0.001). MVA after PSM demonstrated that only MA-NCT was associated with decreased mortality while increasing age, higher Charlson-Deyo index, N1, higher grade, tumor size, and positive margins were associated with higher mortality. Conclusions There was improved OS associated with MA-NCT in pancreatic cancer patients compared to UFS with adjuvant therapy. OS was improved regardless of response to therapy.

Abstract
BACKGROUND While preoperative chemotherapy for patients with stage II-III pancreatic adenocarcinoma (PDAC) is frequently practiced, its impact on very early PDAC (stage I) remains unclear today. MATERIAL AND METHODS Patients undergoing pancreatectomy for PDAC between 2010 and 2016 were identified in the National Cancer Database. Early-stage patients (IA-IB) with complete oncologic and clinical information and more than 30-day survival were included. The effect of preoperative chemotherapy on margin status was assessed with binary logistic regression. Following correction for confounders, the effect of therapy sequencing was assessed via comparison of preoperative, postoperative, perioperative (pre- and post-operative) chemotherapy, and surgery only using Cox regression. RESULTS Of 4785 patients, 688 (14.4%) were stage IA, and 4197 (87.7%) IB. The rate of preoperative chemotherapy was only 8.8%. Rate of margin positivity was lower for preoperative chemotherapy (12.3% vs 19.7%). After correcting for confounders, the risk of a positive margin was lower in preoperative chemotherapy (odd ratio [OR] 0.703, p = 0.042). Cox regression showed a significant overall survival advantage for preoperative (hazard ratio [HR] 0.784, p = 0.002), postoperative (HR 0.618, p < 0.001), and perioperative (HR 0.601, p < 0.001) chemotherapy compared with surgery alone. There was no significant difference in survival between chemotherapy groups but a trend towards optimal survival for preoperative chemotherapy. CONCLUSION Despite preoperative chemotherapy vs surgery alone resulting in improved R0 rates and overall survival even in stage I PDAC, it is rarely practiced. The results presented here suggest that preoperative chemotherapy should be strongly considered in all patients with resectable PDAC, including very early PDAC.

Accuracy of various criteria for lymph node staging in ductal adenocarcinoma of the pancreatic head by computed tomography and magnetic resonance imaging. World J Surg Oncol 2020; 18:213. [PMID: 32811523 PMCID: PMC7436989 DOI: 10.1186/s12957-020-01951-3] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Accepted: 07/07/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Lymph node staging of ductal adenocarcinoma of the pancreatic head (PDAC) by cross-sectional imaging is limited. The aim of this study was to determine the diagnostic accuracy of expanded criteria in nodal staging in PDAC patients. METHODS Sixty-six patients with histologically confirmed PDAC that underwent primary surgery were included in this retrospective IRB-approved study. Cross-sectional imaging studies (CT and/or MRI) were evaluated by a radiologist blinded to histopathology. Number and size of lymph nodes were measured (short-axis diameter) and characterized in terms of expanded morphological criteria of border contour (spiculated, lobulated, and indistinct) and texture (homogeneous or inhomogeneous). Sensitivities and specificities were calculated with histopathology as a reference standard. RESULTS Forty-eight of 66 patients (80%) had histologically confirmed lymph node metastases (pN+). Sensitivity, specificity, and Youden's Index for the criterion "size" were 44.2%, 82.4%, and 0.27; for "inhomogeneous signal intensity" 25.6%, 94.1%, and 0.20; and for "border contour" 62.7%, 52.9%, and 0.16, respectively. There was a significant association between the number of visible lymph nodes on preoperative CT and lymph node involvement (pN+, p = 0.031). CONCLUSION Lymph node staging in PDAC is mainly limited due to low sensitivity for detection of metastatic disease. Using expanded morphological criteria instead of size did not improve regional nodal staging due to sensitivity remaining low. Combining specific criteria yields improved sensitivity with specificity and PPV remaining high.

Abstract
PURPOSE To evaluate the prognostic value of posttreatment fibrosis in human PDAC patients, and to compare a type I collagen targeted MRI probe, CM-101, to the standard contrast agent, Gd-DOTA, for their abilities to identify FOLFIRINOX-induced fibrosis in a murine model of PDAC. EXPERIMENTAL DESIGN Ninety-three chemoradiation-treated human PDAC samples were stained for fibrosis and outcomes evaluated. For imaging, C57BL/6 and FVB mice were orthotopically implanted with PDAC cells and FOLFIRINOX was administered. Mice were imaged with Gd-DOTA and CM-101. RESULTS In humans, post-chemoradiation PDAC tumor fibrosis was associated with longer overall survival (OS) and disease-free survival (DFS) on multivariable analysis (OS P = 0.028, DFS P = 0.047). CPA increased the prognostic accuracy of a multivariable logistic regression model comprised of previously established PDAC risk factors [AUC CPA (-) = 0.76, AUC CPA (+) = 0.82]. In multiple murine orthotopic PDAC models, FOLFIRINOX therapy reduced tumor weight (P < 0.05) and increased tumor fibrosis by collagen staining (P < 0.05). CM-101 MR signal was significantly increased in fibrotic tumor regions. CM-101 signal retention was also increased in the more fibrotic FOLFIRINOX-treated tumors compared with untreated controls (P = 0.027), consistent with selective probe binding to collagen. No treatment-related differences were observed with Gd-DOTA imaging. CONCLUSIONS In humans, post-chemoradiation tumor fibrosis is associated with OS and DFS. In mice, our MR findings indicate that translation of collagen molecular MRI with CM-101 to humans might provide a novel imaging technique to monitor fibrotic response to therapy to assist with prognostication and disease management.

Abstract
The use of neoadjuvant chemoradiation therapy in patients with pancreatic adenocarcinoma is emerg-ing as an acceptable therapy option. The effects of neoadjuvant therapy on 30 days’ outcomes in patients with pancreatic cancer are not well defined in the literature. NSQIP (2009–2012) was used. Only patients with a diagnosis of pancreatic cancer and those who underwent a Whipple were included in the analysis. Patient who underwent neoadjuvant chemoradiation therapy were compared with those who did not receive therapy. Main outcome measures were as follows: complications, ≥2 units of blood transfusions, length of stay, readmission rates, return to the operating room, and 30-day mortality. A total of 1445 patients (395: neoadjuvant chemoradiation and 1050: no neoadjuvant therapy) were identified. The mean age was 67 ± 12 years, and 51 per cent of the patients were male. Neoadjuvant chemoradiation therapy was associated with increase in readmission rates (18% vs 12.2%, P 0.02), unanticipated return to the operating room (2.3% vs 1.1%, P 0.03) with no difference in mortality rates. Neoadjuvant chemoradiation therapy is associated with increase in inhospital complications. These differences in outcomes may be explained by the more advance stage of pancreatic cancer in these subsets of patients. Resource utilization and preoperative rehabilitation are of utmost significance to overcome this rise in complications associated with neoadjuvant chemoradiation therapy.

Abstract
OBJECTIVE Cancer antigen (CA)-125 influences progression, metastasis, and outcomes in pancreatic cancer. This phase I/II trial (NCT01959672) evaluated the safety, efficacy, and immunologic correlates of chemoimmunotherapy (CIT) with oregovomab (anti-CA-125), followed by stereotactic body radiotherapy (SBRT) with the radiosensitizer nelfinavir. MATERIALS AND METHODS Following imaging, pathologic confirmation, and staging laparoscopy, subjects received three 3-week cycles of CIT (gemcitabine/leucovorin/fluorouracil/oregovomab). Thereafter, nelfinavir was delivered (1250 mg bid) for 5 weeks, with SBRT (40 Gy/5 fractions) occurring during the third week of nelfinavir. Following another cycle of CIT, pancreaticoduodenectomy was performed if resectable. Three more cycles of CIT were then delivered (total 7 cycles). In subjects with high (≥10 U/mL) CA-125, oregovomab (2 mg) was administered for 7 total doses (3 pre-SBRT, 1 between SBRT and resection, and 3 postoperatively). The enzyme-linked immunospot assay evaluated the development of CA-125-specific CD8 T-lymphocytes. RESULTS The trial was prematurely closed because gemcitabine/leucovorin/fluorouracil was replaced by FOLFIRINOX and gemcitabine/nab-paclitaxel as the standard of care. Median follow-up was 13 months. Of 11 enrolled patients, 10 had high CA-125; 1 patient suffered an unexpected cardiac-related death, so 9 subjects received oregovomab. Ten received SBRT and 4 underwent resection. Overall, 6/11 patients experienced any grade ≥3 event. The median survival and time to progression were 13 and 8.6 months, respectively. Five patients had samples available for immunospot testing, of whom 2 (40%) developed CA-125-specific CD8 T-lymphocytes. CONCLUSION A combined pancreatic cancer multimodality approach using CIT and radiosensitized radiotherapy is feasible and safe; delivery of immunotherapy can lead to T-cell immunity. Re-evaluation with modern systemic paradigms is recommended.

Abstract
Non-metastatic pancreatic adenocarcinoma (PDAC) is associated with a high rate of recurrence and lethality. In addition, less than half of all patients are able to complete systemic therapy after curative-intent pancreatectomy. With its well-known potential benefits, this report highlights the current prospective data relevant to the use of neoadjuvant systemic therapy in resectable PDAC. Recently, there have been numerous reports, many of which consist of long-awaited multi-intuitional trial data evaluating the use of neoadjuvant systemic chemotherapy in non-metastatic PDAC as well as the use of combination chemotherapy regimens in the adjuvant setting. Currently, recommended guidelines for neoadjuvant systemic therapy only exist for borderline-resectable and locally-advanced disease. Given the plethora of new data, there has been a shift in the paradigm of how resectable pancreatic cancer is treated at certain centers across the world. This review highlights the relevant available data from recent sentinel prospective trials and how they relate to the systemic treatment of resectable PDAC in the neoadjuvant setting.

Abstract
BACKGROUND Multiple trials have demonstrated a survival benefit for adjuvant chemotherapy after resection of pancreatic adenocarcinoma. This study aimed to identify the rate for completion of adjuvant chemotherapy, factors associated with completion, and its impact on survival after surgical resection. METHODS The Surveillance Epidemiology and End Results Medicare-linked data was used to identify patients who underwent upfront resection for pancreatic adenocarcinoma from 2004 to 2013. Billing codes were used to quantify receipt and completion of chemotherapy. Factors associated with completion of chemotherapy were identified using multivariable regression. Kaplan-Meier and Cox proportional-hazards modeling were used to examine survival. RESULTS The inclusion criteria were met by 2440 patients. Of these patients, 65% received no adjuvant chemotherapy, 28% received incomplete therapy, and 7% completed chemotherapy. The factors associated with chemotherapy completion were nodal metastases and treatment at a National Cancer Institute-designated cancer center (p ≤ 0.05). Comorbidities decreased the odds of completion (p ≤ 0.05). The median overall survival (OS) was 14 months for the patients who received no adjuvant chemotherapy, 17 months for those who received incomplete adjuvant chemotherapy, and 22 months for those who completed adjuvant chemotherapy (p ≤ 0.05). More recent diagnosis, comorbidities, T stage, nodal metastases, and no adjuvant chemotherapy were associated with an increased hazard ratio for death (p ≤ 0.05). Evaluation of 15 or more nodes and completion of chemotherapy decreased the hazard ratio for death (p ≤ 0.05). CONCLUSIONS Only 7% of the Medicare patients who underwent upfront resection for pancreatic cancer completed adjuvant chemotherapy, yet completion of adjuvant chemotherapy was associated with improved OS. Completion of adjuvant chemotherapy should be the goal after upfront resection, but neoadjuvant chemotherapy may ensure that patients receive systemic chemotherapy.

Abstract
The aim of this work is to investigate the optimal therapeutic sequence of resectable pancreatic cancer - primary surgery with adjuvant therapy or neoadjuvant followed by resection. Application of the neoadjuvant approach in routine treatment of pancreatic cancer is rapidly growing every year, despite the lack of final results from randomized trials. Recent advancements in the adjuvant therapy, due to the more effective chemotherapy regimens, favor the upfront surgery strategy. On the other hand, theoretical background and metaanalyses favor the neoadjuvant strategy. Currently, primary resection with adjuvant chemotherapy remains the standard approach in resectable pancreatic cancer, but the first recommendations considering the neoadjuvant approach as an option seem to arise among the scientific societies with a global impact. Preliminary results of Prodige 24 study and PREOPANC-1 trial demonstrates that both options are worth further evaluation in clinical trials. Their results should soon provide more answers to this important clinical questions.

Abstract
Background The expression and function of the Receptor for Activated C Kinase 1 (RACK1) in cancer growth and metastasis are confused in different cancers, especially in pancreatic ductal adenocarcinoma (PDAC). Methods One-hundred and eighty-two PDAC tissue specimens (95 males and 87 females) including pancreatic cancer tissue and para-carcinoma tissue were collected for analysis between 2005 to 2012. Blood phenotypic parameters using cell count and capillary electrophoresis were investigated. HE staining, real time PCR, Western blot analysis, and soft agar assays were performed to determine the role of RACK1. Purpose In this study, we aim to determine the specific role of RACK1 in the untility of PDAC. Results We found that RACK1 expression was significantly lower in pancreatic cancer tissue than in para-carcinoma normal pancreatic tissue both in clinic and mice with pancreatic cancer at the early stage. Our results suggested that RACK1 silence could significantly promote cell growth and metastasis of pancreatic cancer cells. But we found that the overexpression of RACK1 has the opposite effect in vitro. In vivo MIAPaca-2 cells overexpressing RACK1, the results demonstrated lower metastatic ability than MIAPaca-2 cells. RACK1 overexpression could decrease the NF-κB transactivation activity of MIAPaca-2 cells, which was consistent with the inhibitory effect of RACK1 overexpression on the pro-migration and pro-invasive target gene of NF-κB, while which could be increased by RACK1 silence. RACK1 silence also enhanced protein expression of pro-migration and pro-invasive NF-κB target genes, which on the contrary, could be reversed by IκBα. Besides, RACK1 expression was significantly associated with lymph node metastasis, vessels metastasis, invasion of nerves as well as TNM staging. The 3-year survival rate of patients with high RACK1 expression was significantly higher than those patients with low RACK1 expression. However, RACK1 expression was not an independent risk factor for of the long-term postoperative survival of patients with pancreatic cancer. Conclusion The obtained results in our study suggested that the low expression of RACK1 was associated with cancer cell growth and metastasis in pancreatic cancer through the activation of the NF-κB pathway. RACK1 could be a potential therapeutic drug target to pancreatic cancer and metastasis.

Phase I trial of concurrent stereotactic body radiotherapy and nelfinavir for locally advanced borderline or unresectable pancreatic adenocarcinoma. Radiother Oncol 2018; 132:55-62. [PMID: 30825970 DOI: 10.1016/j.radonc.2018.11.002] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2018] [Revised: 10/26/2018] [Accepted: 11/05/2018] [Indexed: 01/03/2023]
Abstract
INTRODUCTION The HIV protease inhibitor nelfinavir (NFV) displays notable radiosensitizing effects. There have been no studies evaluating combined stereotactic body radiotherapy (SBRT) and NFV for borderline/unresectable pancreatic cancer. The primary objective of this phase I trial (NCT01068327) was to determine the maximum tolerated SBRT/NFV dose, and secondarily evaluate outcomes. METHODS Following initial imaging, pathologic confirmation, and staging laparoscopy, subjects initially received three 3-week cycles of gemcitabine/leucovorin/fluorouracil; patients without radiologic progression received 5-fraction SBRT/NFV. Dose escalation was as follows: (1) 25 Gy/625 mg BID ×3wks; (2) 25 Gy/1250 mg BID ×3wks; (3) 30 Gy/1250 mg BID ×3wks; (4) 35 Gy/1250 mg BID ×3wks; (5) 35 Gy/1250 mg BID ×5wks; and (6) 40 Gy/1250 mg BID ×5wks. Pancreaticoduodenectomy was performed thereafter if resectable; if not, gemcitabine/leucovorin/fluorouracil was administered. RESULTS Forty-six patients enrolled (10/2008-5/2013); 39 received protocol-directed therapy. Sixteen (41%) experienced any grade ≥2 event during and 1 month after SBRT. Four grade 3 and both grade 4 events occurred in a single patient at the initial dose level. 40 Gy/1250 mg BID ×5wks was the maximum tolerated dose. Five patients had late gastrointestinal bleeding (n = 2 superior mesenteric artery pseudo-aneurysm, n = 1 disease progression, n = 1 lower GI tract, n = 1 unknown location). The median overall survival was 14.4 months. Six (15%) patients recurred locally; median local failure-free survival was not reached. The median distant failure-free survival was 11 months, and median all failure-free survival was 10 months. CONCLUSIONS Concurrent SBRT (40 Gy)/NFV (1250 mg BID) for locally advanced pancreatic cancer is feasible and safe, although careful attention to treatment planning parameters is recommended to reduce the incidence of late gastrointestinal bleeding.

Abstract
PURPOSE Guidelines recommend exercise to cancer survivors, but limited data exists regarding exercise among patients undergoing preoperative cancer treatment. We examined differences in weekly self-reported exercise and accelerometer-measured physical activity among participants in a home-based exercise program administered during preoperative treatment for pancreatic cancer. METHODS Participants were encouraged to perform at least 60 min/week of moderate-intensity aerobic exercise and at least 60 min/week of full-body strengthening exercises concurrent with chemotherapy, chemoradiation therapy or both sequentially and received resistance equipment, program instruction, and biweekly follow-up calls to encourage adherence. Self-reported aerobic and strengthening exercise minutes were measured using daily logs, and physical activity was measured objectively using accelerometers. RESULTS Fifty participants (48% female, mean age 66 ± 8 years) participated for an average of 16 ± 9 preoperative weeks. Participants reported overall means of 126 ± 83 weekly minutes of aerobic exercise and 39 ± 33 weekly minutes of strengthening exercise in daily logs. Participants performed 158.7 ± 146.7 weekly minutes of accelerometer-measured moderate-to-vigorous physical activity. There were no significant differences in exercise or physical activity between treatment phases. CONCLUSIONS These findings suggest that it is feasible to target the entire preoperative course for exercise prescription. Although participants exceeded aerobic exercise recommendations on average, we observed low strengthening exercise adherence and wide variability in self-reported exercise and accelerometer physical activity variables. These findings suggest that additional support, including program adaptations, may be necessary to overcome barriers to exercise or improve motivation when prescribing exercise in this clinical scenario.

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
Syngeneic, immunocompetent allograft tumor models recapitulate important aspects of the tumor microenvironment and have short tumor latency with predictable growth kinetics, making them useful for trialing novel therapeutics. Here, we describe surgical techniques for orthotopic and heterotopic pancreatic ductal adenocarcinoma (PDAC) tumor implantation and characterize phenotypes based on implantation site.Mice (n=8 per group) were implanted with 104 cells in the pancreas or flank. Hy15549 and Han4.13 cell lines were derived from primary murine PDAC (Ptf1-Cre; LSL-KRAS-G12D; Trp53 Lox/+) on C57BL/6 and FVB strains, respectively. Single-cell suspension and solid tumor implants were compared. Tumors were treated with two intravenous doses of FOLFIRINOX and responses evaluated.All mice developed pancreatic tumors within 7 days. Orthotopic tumors grew faster and larger than heterotopic tumors. By 3 weeks, orthotopic mice began losing weight, and showed declines in body condition requiring euthanasia starting at 4 weeks. Single-cell injection into the pancreas had near 100% engraftment, but solid tumor implant engraftment was ∼50% and was associated with growth restriction. Orthotopic tumors were significantly more responsive to intravenous FOLFIRINOX compared with heterotopic tumors, with greater reductions in size and increased apoptosis. Heterotopic tumors were more desmoplastic and hypovascular. However, drug uptake into tumor tissue was equivalent regardless of tumor location or degree of fibrosis, indicating that microenvironment differences between heterotopic and orthotopic tumors influenced response to therapy.Our results show that orthotopic and heterotopic allograft locations confer unique microenvironments that influence growth kinetics, desmoplastic response and angiogenesis. Tumor location influences chemosensitivity to FOLFIRINOX and should inform future preclinical trials.This article has an associated First Person interview with the first author of the paper.

Abstract
BACKGROUND AND AIM To compare cancer-specific survival (CSS) between patients who received neoadjuvant radiation followed by resection (NRR) and those who received upfront resection (UR) for locally advanced pancreatic cancer (LAPC). METHODS A total of 772 LAPC patients who underwent curative-intent surgical resection with or without neoadjuvant radiation from 2004 to 2013 were identified from the Surveillance, Epidemiology, and End Result (SEER) database. Propensity score matching (PSM) was conducted to eliminate possible bias. Kaplan-Meier method was used to analyze long-term outcome. Independent risk factors of CSS were predicted by Cox proportional hazards model. Subgroup analyses were done according to 5 variables. RESULTS The propensity score model matched 196 patients from the whole cohort. Neoadjuvant radiation was an independent predictor of CSS no matter before or after PSM. After PSM, the 1-, 3-, 5-year CSS rates of NRR group were 82.7%, 39.2% and 17.1%, while 64.3%, 19.9% and 12.4% for UR group. The median CSS for NRR group was 25 months, while 17 months for UR group. In subgroup analyses, CSS rates or median CSS of NRR group were still superior to those of UR group in married, unmarried, pancreatic adenocarcinoma, G1+G2, G3+G4, N0 stage, N1 stage and M0 stage subgroups, but no differences were found in other histological types and M1 stage subgroups. Other predictors of CSS included histological type, tumor grade and marital status. CONCLUSIONS Neoadjuvant radiation followed by resection has a significant survival benefit compared with upfront resection in LAPC patients. Therapeutic strategy for LAPC patients should be further explored.

Abstract
Patient-derived xenograft (PDX) tumors are powerful tools to study cancer biology. However, the ability of PDX tumors to model the biological and histological diversity of pancreatic ductal adenocarcinoma (PDAC) is not well known. In this study, we subcutaneously implanted 133 primary and metastatic PDAC tumors into immunodeficient mice. Fifty-seven tumors were successfully engrafted and even after extensive passaging, the histology of poorly-, moderately-, and well-differentiated tumors was maintained in the PDX models. Moreover, the fibroblast and collagen contents in the stroma of patient tumors were recapitulated in the corresponding PDX models. Analysis of the clinicopathological features of patients revealed xenograft tumor engraftment was associated with lymphovascular invasion (P = 0.001) and worse recurrence-free (median, 7 vs. 16 months, log-rank P = 0.047) and overall survival (median, 13 vs. 21 months, log-rank P = 0.038). Among successful engraftments, median time of growth required for reimplantation into new mice was 151 days. Reflective of the inherent biological diversity between PDX tumors with rapid (<151 days) and slow growth, differences in their growth were maintained during extensive passaging. Rapid growth was additionally associated with lymph node metastasis (P = 0.022). The association of lymphovascular invasion and lymph node metastasis with PDX formation and rapid growth may reflect an underlying biological mechanism that allows these tumors to adapt and grow in a new environment. While the ability of PDX tumors to mimic the cellular and non-cellular features of the parental tumor stroma provides a valuable model to study the interaction of PDAC cells with the tumor microenvironment, the association of successful engraftment with adverse clinicopathological features suggests PDX models over represent more aggressive forms of this disease.

Abstract
The management of pancreatic cancer has grown rapidly in the last decade. The Gastrointestinal Tumor Study Group trial in 1985 supported postoperative chemoradiation, and a more recent study recommended 6 months of adjuvant gemcitabine and capecitabine or monotherapy with gemcitabine or fluorouracil plus folinic acid, in the absence of neoadjuvant therapy. Clinicians are now studying the role of targeted therapy in pancreatic cancer and neoadjuvant chemotherapy in resectable, borderline resectable, and locally advanced pancreatic cancer. This article critically evaluates the evolution of pancreatic cancer management, focussing on level 1a, prospective randomized control trials from 2007 to 2017.

Abstract
The purpose of this review was to assess whether neoadjuvant chemotherapy and chemoradiotherapy (CRT) result in differential postoperative morbidity and mortality as compared with pancreatic tumor resection surgery alone. Using PRISMA guidelines and the PubMed search engine, we reviewed all prospective phase II trials of neoadjuvant chemotherapy and CRT for pancreatic cancer that examined postoperative morbidities and mortalities. A total of 30 articles were identified, collated, and analyzed. Risks of postoperative complications vary based on trial. With surgery alone, the most common postoperative complications included delayed gastric emptying (DGE) (17% to 24%), pancreatic fistula (10% to 20%), anastomotic leaks (0% to 15%), postoperative bleeding (2% to 13%), and infections/sepsis (17% to 20%). With surgery alone, the mortality was <5%. Neoadjuvant chemotherapy showed comparable fistula rates (3% to 4%), leaks (3% to 11%), infection (3% to 7%), with mortality 0% to 4% in all but 1 study. CRT for resectable/borderline resectable patients also showed comparable complication rates: DGE (6% to 15%), fistulas (2% to 3%), leaks (3% to 7%), bleeding/hemorrhage (2% to 13%), infections/sepsis (3% to 19%), with 9/13 studies showing a mortality of ≤4%. As compared with initially borderline/resectable tumors, CRT for initially unresectable tumors (despite less data) showed higher complication rates: DGE (13% to 33%), fistulas (3% to 25%), infections/sepsis (3% to 16%). However, the confounding factor of the potentially higher tumor burden as an associative agent remains. The only parameters slightly higher than historical surgery-only complication rates were leaks and bleeding/hemorrhage (13% to 20%). Mortality rates in these patients were consistently 0%, with 2 outliers. Hence, neoadjuvant chemotherapy/CRT is safe from a postoperative complication standpoint, without significant increases in complication rates compared with surgery alone. Resectable and borderline resectable patients have fewer complications as compared with unresectable patients, although data for the latter are lacking.

Abstract
BACKGROUND Recent papers consider surgery as an option for synchronous liver oligometastatic patients [metastatic pancreatic ductal adenocarcinoma (mPDAC)]. In this study, we present our series of resected mPDACs after neoadjuvant chemotherapy (nCT). PATIENTS AND METHODS All patients resected after downstaging of mPDAC were included in this study. Downstaging criteria were disappearance of liver metastasis and a decrease in cancer antigen (CA) 19-9. The type and duration of nCT, last nCT surgery interval, histology, morbidity, and mortality were recorded, and overall survival (OS) and disease-free survival (DFS) were analyzed. RESULTS Overall, 24 of 535 patients (4.5%) observed with mPDAC were included. These patients received gemcitabine alone (5/24), gemcitabine + nanoparticle albumin-bound (nab)-paclitaxel (3/24), and FOLFIRINOX (16/24). Primary tumor size decreased from 31 to 19 mm (p < 0.001), and serum CA19-9 decreased from 596 to 18 U/mL (p < 0.001). In 14/24 patients, the tumor was located in the head. Median interval nCT surgery was 2 months, there were no mortalities, and the postoperative course was uneventful in 34% of cases. Grade B/C pancreatic fistula, postoperative bleeding, and sepsis occurred in 17/4, 4, and 12% of cases, respectively, and reoperation rate was 4%. R0 resection was achieved in 88% of cases, with 17% complete pathological response. Positive nodes were found in 9/24 patients with a median node ratio of 0.37, and OS and DFS was 56 and 27 months, respectively. CONCLUSIONS Patients with mPDAC who were fully responsive to nCT may be cautiously considered for surgery, with potential benefit in survival compared with palliative chemotherapy alone. This is supported by results of our retrospective study, which is the largest ever reported.

Abstract
Chemotherapy for pancreatic cancer has diversified following the addition of more treatment regimens; however, in spite of this, pancreatic cancer remains a fatal disease. Preoperative (neoadjuvant) chemotherapy (NAC) or neoadjuvant chemoradiation therapy (NACRT) has been developed and implemented. For patients with borderline resectable pancreatic cancer (BRPC) and locally advanced pancreatic cancer (LAPC), a number of clinical trials have been conducted; NACRT was demonstrated to improve resectability, R0 resection rate, overall survival rate, disease-free survival rate and even an LAPC and BRPC survival advantage over NAC. However, from the knowledge obtained from resected specimens following preoperative treatment, residual pancreatic cancer tissues following NAC are rich in chemoresistant cancer stem-like cells and epithelial-mesenchymal transition (EMT) markers. Conversely, metformin, angiotensin receptor blocker, statins and low-dose paclitaxel are well-known as drugs that inhibit EMT, which is associated with cancer stem cell-like characteristics. Although clinical effectiveness is unlikely to be achieved using one of these as an anticancer agent, it is reasonable to use these drugs for patients with comorbidities in the treatment of pancreatic cancer. Furthermore, gemcitabine (GEM) affects antitumor immunity by stimulating the expression of major histocompatibility complex class I-related chain A on the surface of cancer cells to enhance the cytotoxicity of natural killer cells. Considering EMT and antitumor immunity, there is a possibility that GEM and nanoparticle albumin-bound paclitaxel therapy is the most suitable regimen for treating pancreatic cancer. However, even as preoperative treatment progresses, R0 resection is the most important factor for the long-term survival of pancreatic cancer patients.

Abstract
Borderline resectable pancreatic cancer is now recognized as a distinct clinical entity. In these cases, neoadjuvant treatment could maximize the potential for an R0 resection and avoid R1/R2 resections. In fact, by analyzing, the current literature is evident that approximately one-third of initially borderline resectable pancreatic tumors may undergo successful resection following neoadjuvant therapy. However, the enormous difficulties in achieving a consensus and the variability in therapeutic algorithms have delayed progress in establishing strong evidence-based practices for diagnosis and treatment. In addition, the absence of a unique definition of borderline resectable pancreatic cancer remains a great obstacle for planning a therapeutic strategy and surgical decision-making. If on the one hand, we can finally say that the presence of only few prospective trials generates no strong data to support a specific neoadjuvant therapy regimen in borderline resectable pancreatic cancer, on the other hand, there are many studies on patients with borderline resectable pancreatic cancer who receive neoadjuvant therapy that can enjoy an R0 resection with similar outcomes to up-front resectable disease.

Abstract
PURPOSE OF REVIEW Radiofrequency ablation (RFA) has been recognized for its potential in palliative treatment for pancreatic cancer as well as malignant biliary strictures. The purpose of this review is to describe the technology, endoscopic technique, and reported outcomes of endoscopic RFA in the management of malignant biliary strictures and unresectable pancreatic cancer. RECENT FINDINGS Intraductal biliary RFA is safe and feasible and appears to confer a survival advantage. Pancreatic endoscopic ultrasound-guided RFA is a promising new technique and may result in either resolution of tumor or reduction in size. SUMMARY Intraductal biliary RFA and pancreatic endoscopic ultrasound-guided RFA are important modalities in malignant biliary obstruction and unresectable pancreatic cancer. Intraductal biliary RFA should be used as an adjunct to biliary stenting. Further trials are needed to determine if RFA leads to a benefit in pancreatic cancer treatment. Two prospective trials are currently underway to determine if intraductal biliary RFA indeed confers a survival advantage in malignant obstruction.

Abstract
Currently, pancreatic adenocarcinoma mainly occurs after 60 years of age, and its prognosis remains poor despite modest improvements in recent decades. The aging of the population will result in a rise in the incidence of pancreatic adenocarcinoma within the next years. Thus, the management of pancreatic cancer in the elderly population is gaining increasing relevance. Older cancer patients represent a heterogeneous group with different biological, functional and psychosocial characteristics that can modify the usual management of this disease, including pharmacokinetic and pharmacodynamic changes, polypharmacy, performance status, comorbidities and organ dysfunction. However, the biological age, not the chronological age, of the patient should be the limiting factor in determining the most appropriate treatment for these patients. Unfortunately, despite the increased incidence of this pathology in older patients, there is an underrepresentation of these patients in clinical trials, and the management of older patients is thus determined by extrapolation from the results of studies performed in younger patients. In this review, the special characteristics of the elderly, the multidisciplinary management of localized and advanced ductal adenocarcinoma of the pancreas and the most recent advances in the management of this condition will be discussed, focusing on surgery, chemotherapy, radiation and palliative care.

Abstract
BACKGROUND Radiofrequency ablation of malignant biliary strictures has been offered for the last 3 years, but only limited data have been published. AIM To assess the safety, efficacy, and survival outcomes of patients receiving endoscopic radiofrequency ablation. METHODS Between April 2010 and December 2013, 69 patients with unresectable neoplastic lesions and malignant biliary obstruction underwent 98 radiofrequency ablation sessions with stenting. RESULTS A total of 69 patients (22 male, aged 66.1 ± 13.3) were included in the registry. The etiology of malignant biliary stricture included unresectable cholangiocarcinoma (n = 45), pancreatic cancer (n = 19), gallbladder cancer (n = 2), gastric cancer (n = 1), and liver metastasis from colon cancer (n = 3). Seventy-eight percentage of patients had prior chemotherapy. All strictures were stented post-radiofrequency ablation with either plastic stents or metal stents. The mean stricture length treated was 14.3 mm. There was a statistically significant improvement in stricture diameter post-ablation (p < 0.0001). The likelihood of stricture improvement was significantly greater in pancreatic cancer-associated strictures [RR 1.8 (95 % 1.03-5.38)]. Seven patients (10 %) had adverse events, not linked directly to radiofrequency ablation. Median survival was 11.46 months (6.2-25 months). CONCLUSION Radiofrequency ablation is effective and safe in malignant biliary obstruction and seems to be associated with improved survival.
