Abstract
BACKGROUND T cell exhaustion and activation markers are helpful in determining the therapies and predicting the overall survival in pancreatic cancer (PC) patients. PURPOSE In this systematic review, we have addressed two questions, how do these markers differ in their expression levels in PC patients and healthy individual and correlating the expression level of these markers with the cancer stage. METHODS The systematic review was registered with Prospective Register of Systematic Reviews (PROSPERO) with registration number "CRD42022246780." All the included articles were obtained from three databases, PubMed, MEDLINE, and Cochrane, published from January 2010 to 26th May 2022. Two independent reviewers followed the PRISM protocol and reviewed and extracted data from the included articles. RESULTS PD-1 and CTLA-4 were the most studied markers in this field. A clear elevation in the expression of PD-1, CTLA-4, TIM-3, LAG-3, and TIGIT was found in most of the studies. CD69, CD25, and HLA-DR expression was found to be upregulated after chemotherapy and immunotherapy. CD25 was the only marker analyzed against cancer progression, in a single study. No study compared the expression of exhaustion and activation markers (except CD69) with the cancer progression of the tumor stage. CONCLUSION Since the exhaustion markers are upregulated in patients, single or multiple markers can be targeted in immunotherapies. Knowledge of the dynamics of these markers at various cancer stages will help in determining the right immunotherapy for pancreatic cancer patients. Stage-wise comparison could also be made possible by developing in vitro models.

Abstract
Doxorubicin (Dox), a widely used treatment for cancer, can result in chemotherapy-induced cognitive impairments (chemobrain). Chemobrain is associated with inflammation and oxidative stress similar to aging. As such, Dox treatment has also been used as a model of aging. However, it is unclear if Dox induces brain changes similar to that observed during aging since Dox does not readily enter the brain. Rather, the mechanism for chemobrain likely involves the induction of peripheral cellular senescence and the release of senescence-associated secretory phenotype (SASP) factors and these SASP factors can enter the brain to disrupt cognition. We examined the effect of Dox on peripheral and brain markers of aging and cognition. In addition, we employed the senolytic, ABT-263, which also has limited access to the brain. The results indicate that plasma SASP factors enter the brain, activating microglia, increasing oxidative stress, and altering gene transcription. In turn, the synaptic function required for memory was reduced in response to altered redox signaling. ABT-263 prevented or limited most of the Dox-induced effects. The results emphasize a link between cognitive decline and the release of SASP factors from peripheral senescent cells and indicate some differences as well as similarities between advanced age and Dox treatment.

Abstract
BACKGROUND There has been increasing interest into the role of germline BRCA1/2 pathogenic variants (gBRCA PV) and gATM PV and likely PV (PV and LPV; PV + LPV) in the carcinogenesis and treatment of pancreatic cancer (PC), but the clinical features have not been well described. METHODS Patients with confirmed gBRCA PV and gATM PV + LPV PC treated at our hospital between April 2016 and December 2021, were retrospectively evaluated for clinical characteristics and outcomes. RESULTS Twenty-two patients harbored gBRCA PV and three patients harbored gATM PV + LPV. Of the gBRCA PV patients, 81.8 % received platinum-based chemotherapy with favorable treatment outcomes with an objective response rate of 50.0 % (95 % CI: 23.0-77.0), median progression free survival (PFS) of 334 days, and median overall survival (OS) of 926 days from the initiation of first-line chemotherapy. The annual number of patients with gBRCA PV was two patients per year before January 2021 (when BRACAnalysis became available in Japan), and ten patients during the 10 months thereafter. Four patients (20 %) with gBRCA PV developed soft-tissue metastasis with progression. Two patients with gATM PV + LPV received platinum-based chemotherapy and the best response of those patients was partial response and stable disease and their OS from the initiation of first-line chemotherapy was 1192 and 989 days, and PFS was 579 and 140 days, respectively. CONCLUSION The diagnosis of gBRCA PV-positive PC has increased revealed in recent years. These tumors appear to be sensitive to platinum-based chemotherapy, with long term survival observed in gATM PV + LPV-positive patients.

Abstract
Over the last two decades, there have been many reported advances in the clinical management of pancreatic ductal adenocarcinoma (PDAC). We sought to evaluate changes in survival for patients diagnosed with PDAC between 2004 and 2017. The National Cancer Database was queried for patients diagnosed with PDAC between 2004 and 2017. There were 55,401 patients who underwent surgery and 109,477 patients who underwent non-surgical treatment for PDAC between 2004 and 2017. Patients were categorized into four groups by year of diagnosis. Median survival improved from 15.5 months to 25.3 months for patients treated with surgery between the years 2016 and 2017 compared with between 2004 and 2007 (p < 0.001). Median survival improved from 7.2 months to 10.1 months for patients treated without surgery during the same years (p < 0.001). On multivariable analysis, the hazard ratio for death was estimated to multiply by 0.975 per year for patients treated with surgery and 0.959 per year for patients treated without surgery (p < 0.001). This increase in survival in the setting of evolving care validates continued efforts aimed at improving survival for patients with this devastating disease.

Abstract
INTRODUCTION Guidelines endorse pancreatic cancer screening in genetically susceptible individuals. We conducted a prospective, multicenter study to determine yield, harms, and outcomes of pancreatic cancer screening. METHODS All high-risk individuals undergoing pancreatic cancer screening at 5 centers from 2020 to 2022 were prospectively enrolled. Pancreas findings were designated as low-risk (fatty or chronic pancreatitis-like changes), intermediate-risk (neuroendocrine tumor [NET] <2 cm or branch-duct intraductal papillary mucinous neoplasm [IPMN]), or high-risk lesions (high-grade pancreatic intraepithelial neoplasia/dysplasia, main-duct IPMN, NET >2 cm, or pancreatic cancer). Harms from screening included adverse events during screening or undergoing low-yield pancreatic surgery. Annual screening was performed using endoscopic ultrasound and or magnetic resonance cholangiopancreatography. Annual screening for new-onset diabetes using fasting blood sugar was also performed ( ClinicalTrials.gov : NCT05006131). RESULTS During the study period, 252 patients underwent pancreatic cancer screening. Mean age was 59.9 years, 69% were female, and 79.4% were White. Common indications were BRCA 1/2 (36.9%), familial pancreatic cancer syndrome kindred (31.7%), ataxia telangiectasia mutated (3.5%), Lynch syndrome (6.7%), Peutz-Jeghers (4.3%), and familial atypical multiple mole melanoma (3.5%). Low-risk lesions were noted in 23.4% and intermediate-risk lesions in 31.7%, almost all of which were branch-duct IPMN without worrisome features. High-risk lesions were noted in 2 patients (0.8%), who were diagnosed with pancreas cancer at stages T2N1M0 and T2N1M1. Prediabetes was noted in 18.2% and new-onset diabetes in 1.7%. Abnormal fasting blood sugar was not associated with pancreatic lesions. There were no adverse events from screening tests, and no patient underwent low-yield pancreatic surgery. DISCUSSION Pancreatic cancer screening detected high-risk lesions with lower frequency than previously reported. No harms from screening were noted.

Role of Immune Microenvironment in Pancreatic Ductal Adenocarcinoma: Could It Be Considered a Predictor of Prognosis? Curr Oncol 2023; 30:5515-5528.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is characterized by a highly immunosuppressive tumor microenvironment (TME). The aim of this study is to determine the potential significant TME immune markers of long-term survival. METHODS We retrospectively included patients with a diagnosis of resectable PDAC having undergone upfront surgery. Immunohistochemical (IHC) staining using tissue microarray for PD-L1, CD3, CD4, CD8, FOXP3, CD20, iNOS and CD163 was performed in order to characterize the TME. The primary endpoint was long-term survival, defined as the Overall Survival > 24 months from surgery. RESULTS A total of 38 consecutive patients were included, and 14 (36%) of them were long-term survivors. Long-term survivors showed a higher density of CD8+ lymphocytes intra- and peri-acinar (p = 0.08), and a higher CD8/FOXP3 intra- and peri-tumoral ratio (p = 0.05). A low density of intra- and peri-tumoral FOXP3 infiltration is a good predictor of long-term survival (p = 0.04). A significant association of the low density of intra- and peri-tumoral tumor-associated macrophages (TAMs) iNOS+ with long-term survival was detected (p = 0.04). CONCLUSIONS Despite the retrospective nature and small sample size, our study showed that the high infiltration of CD8+ lymphocytes and low infiltration of FOXP3+ and TAMs iNOS+ are predictors of good prognosis. A preoperative assessment of these potential immune markers could be useful and determinant in the staging process and in PDAC management.

Abstract
BACKGROUND Commensal bacteria secrete metabolites that reach distant cancer cells through the circulation and influence cancer behavior. Deoxycholic acid (DCA), a hormone-like metabolite, is a secondary bile acid specifically synthesized by intestinal microbes. DCA may have both pro- and antineoplastic effects in cancers. METHODS AND RESULTS The pancreatic adenocarcinoma cell lines, Capan-2 and BxPC-3, were treated with 0.7 µM DCA, which corresponds to the reference concentration of DCA in human serum. DCA influenced the expression of epithelial to mesenchymal transition (EMT)-related genes, significantly decreased the expression level of the mesenchymal markers, transcription factor 7- like 2 (TCF7L2), snail family transcriptional repressor 2 (SLUG), CLAUDIN-1, and increased the expression of the epithelial genes, zona occludens 1 (ZO-1) and E-CADHERIN, as shown by real-time PCR and Western blotting. Consequently, DCA reduced the invasion capacity of pancreatic adenocarcinoma cells in Boyden chamber experiments. DCA induced the protein expression of oxidative/nitrosative stress markers. Moreover, DCA reduced aldehyde dehydrogenase 1 (ALDH1) activity in an Aldefluor assay and ALDH1 protein level, suggesting that DCA reduced stemness in pancreatic adenocarcinoma. In Seahorse experiments, DCA induced all fractions of mitochondrial respiration and glycolytic flux. The ratio of mitochondrial oxidation and glycolysis did not change after DCA treatment, suggesting that cells became hypermetabolic. CONCLUSION DCA induced antineoplastic effects in pancreatic adenocarcinoma cells by inhibiting EMT, reducing cancer stemness, and inducing oxidative/nitrosative stress and procarcinogenic effects such as hypermetabolic bioenergetics.

Abstract
BACKGROUND Pancreatic cancer (PC) is the third leading cause of cancer death. Obesity can increase the risk of PC by up to 50%. Studies have shown racial and gender disparities in PC, however, there is a paucity of such information in obese PC patients. AIM The aim of this study was to: (1) evaluate the incidence and prevalence of obesity among PC patients in the United States over the last 15 years, and (2) determine if variation exists in the demographic of obese PC patients over the last 15 years. It is hoped that this information could be used to assist in primary prevention and early detection of PC. METHODS A population-based retrospective analysis in IBM Explorys, a pooled, national, deidentified database of 63 million patients from 300 hospitals in the United States. Patient populations were identified using SNOMED and ICD codes. Cochrane-Armitage testing was performed to analyze trends in obesity among PC. Subgroup analysis for gender, age, race, and mortality rate were assessed. RESULTS The percentage of obese patients with PC increased over the 15-year period (2.5% to 8.5%, P <0.0001). Rates of obesity among PC patients increased among females ( P =0.0004), individuals under age 65 years ( P =0.0002), and all races, but especially for African Americans ( P =0.0007) and those in minority groups. CONCLUSION Awareness of disparities in PC and applying targeted care to those at increased risk are essential to improve future outcomes, including increased health care access and recruitment in research studies for minority groups.

Abstract
OBJECTIVE Determining the impact of county-level upward economic mobility on stage at diagnosis and receipt of treatment among Medicare beneficiaries with pancreatic adenocarcinoma. SUMMARY BACKGROUND DATA The extent to which economic mobility contributes to socioeconomic disparities in health outcomes remains largely unknown. METHODS Pancreatic adenocarcinoma patients diagnosed in 2004-2015 were identified from the SEER-Medicare linked database. Information on countylevel upward economic mobility was obtained from the Opportunity Atlas. Its impact on early-stage diagnosis (stage I or II), as well as receipt of chemotherapy or surgery was analyzed, stratified by patient race/ethnicity. RESULTS Among 25,233 patients with pancreatic adenocarcinoma, 37.1% (n = 9349) were diagnosed at an early stage; only 16.7% (n = 4218) underwent resection, whereas 31.7% (n = 7996) received chemotherapy. In turn, 10,073 (39.9%) patients received any treatment. Individuals from counties with high upward economic mobility were more likely to be diagnosed at an earlier stage (odds ratio [OR] 1.15, 95% confidence interval [CI] 1.07-1.25), as well as to receive surgery (OR 1.58, 95% CI 1.41-1.77) or chemotherapy (OR 1.51, 95% CI 1.39-1.63). White patients and patients who identified as neither White or Black had increased odds of being diagnosed at an early stage (OR 1.12, 95% CI 1.02-1.22 and OR 1.35, 95% CI 1.02-1.80, respectively) and of receiving treatment (OR 1.73, 95% CI 1.59-1.88 and OR 1.49, 95% CI 1.13-1.98, respectively) when they resided in a county of high vs low upward economic mobility. The impact of economic mobility on stage at diagnosis and receipt of treatment was much less pronounced among Black patients (high vs low, OR 1.28, 95% CI 0.96-1.71 and OR 1.30, 95% CI 0.99-1.72, respectively). CONCLUSIONS Pancreatic adenocarcinoma patients from higher upward mobility areas were more likely to be diagnosed at an earlier stage, as well as to receive surgery or chemotherapy. The impact of county-level upward mobility was less pronounced among Black patients.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignant solid tumours, and abnormal metabolic reprogramming in the tumour microenvironment is regarded as an important contributor to its pathogenesis. OBJECTIVES As there is an urgency to identify new targets based on the metabolic features that are highly refractory to PDAC treatment, this study aimed to identify suitable therapeutic targets for PDAC. METHODS In this study, gene set enrichment and Kyoto Encyclopedia of Genes and Genomes analyses were performed on 163 PDAC tissue samples and 165 normal pancreatic tissue samples from The Cancer Genome Atlas and Genotype-Tissue Expression databases to identify alterations in critical metabolites that may contribute to PDAC pathogenesis. Furthermore, ultra-performance liquid chromatography-tandem mass spectrometry was performed to identify significant metabolic pathways between 24 pairs of tumour and adjacent non-tumour tissues and between serum samples from PDAC patients and healthy donors. RESULTS Fifty-one tissue metabolites and 26 serum metabolites were altered in PDAC. Among them, those in the γ-glutamyl cycle were the most substantially changed, and 5-oxoproline was the biomarker of PDAC with the most significantly decreased levels. CONCLUSIONS The γ-glutamyl cycle and 5-oxoproline might be potential biomarkers and therapeutic targets to improve the diagnosis, therapy, and prognosis of PDAC.

Abstract
Background The 5-year survival rate for pancreatic cancer (PC) is incredibly low, resulting in this often being a fatal disease. Timely and accurate assessment of the survival rate and prognosis of patients with PC is of great significance for the development of new programs for prevention, monitoring, and treatment. Methods Period analysis and further stratified analysis were used to determine the 5-year relative survival rate (RSR) of patients with PC from 2002 to 2016 using the Surveillance, Epidemiology, and End Results (SEER) project database of the National Cancer Institute. Based on this, a generalized linear model was created to predict the survival rate of patients from 2017 to 2021. Result During 2002-2016, the 5-year RSR of patients with PC increased from 7.9 to 23.7%. The generalized linear model predicted that the survival rate had increased to 33.9% during 2017-2021, and hence, it was still unacceptably low. The survival rate of patients aged ≥75 years at diagnosis was the lowest among all age groups and was predicted to be only 21.4% during 2017-2021. Notably, the survival rate of patients with differentiation grade III at diagnosis remains particularly low at 7.6%. Conclusion The survival rates of patients with PC, although slightly improved, remain extremely low. Timely assessment of the trend of survival rate changes in patients with PC further improves the prognosis of tumor patients and provides data support for relevant medical works to formulate effective tumor prevention and control policies.

Abstract
BACKGROUND Survival from pancreatic cancer is low worldwide. In the US, the 5-year relative survival has been slightly higher for women, whites and younger patients than for their counterparts, and differences in age and stage at diagnosis [Corrections added Nov 16, 2022, after first online publication: a new affiliation is added to Maja Nikšić] may contribute to this pattern. We aimed to examine trends in survival by race, stage, age and sex for adults (15-99 years) diagnosed with pancreatic cancer in the US. METHODS This population-based study included 399,427 adults registered with pancreatic cancer in 41 US state cancer registries during 2001-2014, with follow-up to December 31, 2014. We estimated age-specific and age-standardized net survival at 1 and 5 years. RESULTS Overall, 12.3% of patients were blacks, and 84.2% were whites. About 9.5% of patients were diagnosed with localized disease, but 50.5% were diagnosed at an advanced stage; slightly more among blacks, mainly among men. No substantial changes were seen over time (2001-2003, 2004-2008, 2009-2014). In general, 1-year net survival was higher in whites than in blacks (26.1% vs. 22.1% during 2001-2003, 35.1% vs. 31.4% during 2009-2014). This difference was particularly evident among patients with localized disease (49.6% in whites vs. 44.6% in blacks during 2001-2003, 60.1% vs. 55.3% during 2009-2014). The survival gap between blacks and whites with localized disease was persistent at 5 years after diagnosis, and it widened over time (from 24.0% vs. 21.3% during 2001-2003 to 39.7% vs. 31.0% during 2009-2014). The survival gap was wider among men than among women. CONCLUSIONS Gaps in 1- and 5-year survival between blacks and whites were persistent throughout 2001-2014, especially for patients diagnosed with a localized tumor, for which surgery is currently the only treatment modality with the potential for cure.

Abstract
Evidence on pancreatic cancer (PaCa) risk factors from large population-based cohort studies is limited. This study investigated the PaCa risk factors and the population attributable fraction (PAF) of modifiable risk factors in the UK Biobank cohort. The UK Biobank is a prospective cohort consisting of 502,413 participants with a mean follow-up time of 8.2 years. A binomial generalized linear regression model was used to calculate relative risks for PaCa risk factors. PAF was calculated to estimate the proportional reduction in PaCa if modifiable risk factors were to be eliminated. A total of 728 (0.14%) PaCa incident cases and 412,922 (82.19%) non-PaCa controls were analyzed. The non-modifiable risk factors included age and gender. The modifiable risk factors were cigarette smoking, overweight and obesity, increased waist circumstance, abdominal obesity, Diabetic Mellitus (DM), and pancreatitis history. The PAF suggested that eliminating smoking and obesity can contribute around a 16% reduction in PaCa cases while avoiding abdominal obesity can eliminate PaCa cases by 22%. Preventing pancreatitis and DM could potentially reduce PaCa cases by 1% and 6%, respectively. This study has identified modifiable and non-modifiable PaCa risk factors in the UK population. The PAF of modifiable risk factors can be applied to inform PaCa prevention programs.

Abstract
BACKGROUND Systemic therapy is a key management component of pancreatic ductal adenocarcinoma(PDAC). Racial disparities exist in PDAC, often linked to socioeconomic variables. We investigated the impact of race in PDAC patients who had undergone systemic therapy and surgical resection. METHODS A retrospective analysis was performed for all patients who underwent surgical resection for PDAC from 2010 to 2018. RESULTS 234 patients (78.2% White; 21.8% Black) were included. Black patients presented at a younger age with larger tumors. White patients benefited from systemic therapy with longer overall survival (35vs20 months, p = 0.002). This survival advantage was not present in Black patients (21vs15 months, p = 0.15). Black patients receiving systemic therapy had similar survival as White patients who did not (p = 0.81). CONCLUSION Black PDAC patients present at younger ages and with larger initial tumors. In our population, White patients had a longer overall survival after both surgical and systemic therapy. These findings may indicate differences in tumor biology. Further prospective studies are needed.

Abstract
Background Pancreatic ductal adenocarcinoma (PDAC) is a fatal malignancy with a low resection rate. Chemotherapy and radiotherapy (RT) are the main treatment approaches for patients with advanced pancreatic cancer, and neoadjuvant chemoradiotherapy is considered a promising strategy to increase the resection rate. Recently, immune checkpoint inhibitor (ICI) therapy has shown remarkable efficacy in several cancers. Therefore, the combination of ICI, chemotherapy, and concurrent radiotherapy is promising for patients with potentially resectable pancreatic cancer, mainly referring to locally advanced (LAPC) and borderline resectable pancreatic cancer (BRPC), to increase the chances of conversion to surgical resectability and prolong survival. This study aims to introduce the design of a clinical trial. Methods This is an open-label, single-arm, and single-center phase II trial. Patients with pathologically and radiographically confirmed LAPC or BRPC without prior anti-cancer treatment or severe morbidities will be enrolled. All patients will receive induction therapy and will be further evaluated by the Multiple Disciplinary Team (MDT) for the possibility of surgery. The induction therapy consists of up to four cycles of gemcitabine 1,000 mg/m2 and nab-paclitaxel 125 mg/m2via intravenous (IV) infusion on days 1 and 8, along with tislelizumab (a PD-1 monoclonal antibody) 200 mg administered through IV infusion on day 1 every 3 weeks, concurrently with stereotactic body radiation therapy (SBRT) during the third cycle of treatment. After surgery, patients without progression will receive another two to four cycles of adjuvant therapy with gemcitabine, nab-paclitaxel, and tislelizumab. The primary objectives are objective response rate (ORR) and the R0 resection rate. The secondary objectives are median overall survival (mOS), median progression free survival (mPFS), disease control rate (DCR), pathological grade of tumor tissue after therapy, and adverse reactions. Besides, we expect to explore the value of circulating tumor DNA (ctDNA) in predicting tumor response to induction therapy and survival outcome of patients. Discussion This is a protocol for a clinical trial that attempts to evaluate the safety and efficacy of the combination of anti-PD-1 antibody plus chemotherapy and radiotherapy as the induction therapy for LAPC and BRPC. The results of this phase II study will provide evidence for the clinical practice of this modality.

A systematic review of prognosis predictive role of radiomics in pancreatic cancer: heterogeneity markers or statistical tricks? Eur Radiol 2022; 32:8443-8452. [PMID: 35904618 DOI: 10.1007/s00330-022-08922-0] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2021] [Revised: 04/07/2022] [Accepted: 05/30/2022] [Indexed: 12/14/2022]
Abstract
OBJECTIVES We aimed to systematically evaluate the prognostic prediction accuracy of radiomics features extracted from pre-treatment imaging in patients with pancreatic ductal adenocarcinoma (PDAC). METHODS Radiomics literature on overall survival (OS) prediction of PDAC were all included in this systematic review. A further meta-analysis was performed on the effect size of first-order entropy. Methodological quality and risk of bias of the included studies were assessed by the radiomics quality score (RQS) and prediction model risk of bias assessment tool (PROBAST). RESULTS Twenty-three studies were finally identified in this review. Two (8.7%) studies compared prognosis prediction ability between radiomics model and TNM staging model by C-index, and both showed a better performance of the radiomics. Twenty-one (91.3%) studies reported significant predictive values of radiomics features. Nine (39.1%) studies were included in the meta-analysis, and it showed a significant correlation between first-order entropy and OS (HR 1.66, 95%CI 1.18-2.34). RQS assessment revealed validation was only performed in 5 (21.7%) studies on internal datasets and 2 (8.7%) studies on external datasets. PROBAST showed that 22 (95.7%) studies have a high risk of bias in participants because of the retrospective study design. CONCLUSION First-order entropy was significantly associated with OS and might improve the accuracy of PDAC prognosis prediction. Existing studies were poorly validated, and it should be noted in future studies. Modification of PROBAST for radiomics studies is necessary since the strict requirements of prospective study design may not be applicable to the demand for a large sample size in the model construction stage. KEY POINTS • Radiomics based on the primary lesion holds great potential for prognosis prediction. First-order entropy was significantly associated with the overall survival of PDAC and might improve the accuracy of current PDAC prognosis prediction. • We strongly recommend that at least an internal validation should be conducted in any radiomics study. Attention should be paid to the complex relationships between radiomics features. • Due to the close relationship between radiomics and big data, the strict requirement of prospective study design in PROABST may not be appropriate for radiomics studies. A balance between study types and sample sizes for radiomics studies needs to be found in the model construction stage.

Outcomes of Lymphoma Among American Adolescent and Young Adult Patients Varied by Health Insurance-A SEER-based Study. J Pediatr Hematol Oncol 2022; 44:e403-e412. [PMID: 34486562 DOI: 10.1097/mph.0000000000002314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2021] [Accepted: 08/06/2021] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Impacts of health insurance status on survival outcomes among adolescent and young adult (AYA, 15 to 39 years of age) patients with lymphoma in the United States are insufficiently known. This study aimed to clarify associations between health insurance status and overall survival (OS) estimates in this population. MATERIALS AND METHODS We examined 18 Surveillance, Epidemiology, and End Results registries in the United States and analyzed American AYA patients with lymphoma diagnosed during January 2007 and December 2016. Health insurance status was categorized, and Kaplan-Meier and multifactor Cox regressions were adopted using hazard ratio and 95% confidence interval. Probable baseline confounding was modulated by multiple propensity score. RESULTS A total of 21,149 patients were considered; ~28% were 18 to 25 years old, and 63.5% and 7.5% had private and no insurance, respectively. Private insurance rates increased in the 18 to 25 age group (60.1% to 6.1%, P<0.001) following the 2010 Patient Protection and Affordable Care Act (ACA), and lymphoma survival rates improved slightly 1 to 5 years postdiagnosis. Five-year OS rates decreased with age (93.9%, 90.4%, and 87.0% at 15 to 17, 18 to 25, and 26 to 39, respectively) and differed among insurance conditions (81.7%, 79.2%, 89.2%, and 92.0% for uninsured, Medicaid, insured, and insured/no specifics, respectively). Risk of death was significantly higher for those with Medicaid or no insurance than for those with private insurance in multiple propensity score-adjusted models (hazard ratio [95% confidence interval]=1.07 [1.03-1.12]), independent of stage at diagnosis. CONCLUSIONS No or insufficient insurance was linked to poor OS in our sample in exposure-outcome association analysis. Insurance coverage and health care availability may enhance disparate outcomes of AYAs with cancer. The ACA has improved insurance coverage and survival rates for out sample. Nevertheless, strategies are needed to identify causality and eliminate disparities.

Abstract
INTRODUCTION The centralisation of pancreatic cancer (PC) services still varies worldwide. This study aimed to assess the impact that a centralisation has had on patients in South Wales, UK. METHODS A retrospective cohort analysis of patients in South Wales, UK, with PC prior to (2004-2009), and after (2010-2014) the formation of a specialist centre. Patients were identified using record linkage of electronic health records. RESULTS The overall survival (OS) of all 3413 patients with PC increased from a median (IQR) 10 weeks (3-31) to 11 weeks (4-35), p = 0.038, after centralisation. The OS of patients undergoing surgical resection or chemotherapy alone did not improve (93 weeks (39-203) vs. 90 weeks (50-95), p = 0.764 and 33 weeks (20-57) vs. 33 weeks (19-58), p = 0.793). Surgical resection and chemotherapy rates increased (6.1% vs. 9.2%, p < 0.001 and 19.7% vs. 27.0%, p < 0.001). The 30-day mortality rate trended downwards (7.2% vs. 3.6%, p = 0.186). The percentage of patients who received no treatment reduced (75.2% vs. 69.6%, p < 0.001). CONCLUSION The centralisation of PC services in South Wales is associated with a small increase in OS and a larger increase in PC treatment utilisation. It is concerning that many patients still fail to receive any treatments.

Abstract
BACKGROUND To explain the difference in the incidence and relative survival in a population-based cohort of women with epithelial ovarian cancer (EOC) postdiagnosis in the last forty years. EOC is the most common type of all ovarian cancers, but there is inadequate information about the variations related to long-term EOC survival. METHODS We acquired the incidence and relative survival rate data from the Surveillance, Epidemiology, and End Results (SEER) registries to analyze the epidemiological variations from 1974 to 2013 in EOC-affected individuals. The survival disparities in EOC-specific individuals due to age, race, and socioeconomic status (SES) were performed by Kaplan-Meier analysis. The Results. The overall incidence of EOC progressively declined to 9.0 per 100,000 from 11.4 in the last forty years. The median survival rate improved to 48 months in the first decade from a previous of 27 months in the fourth decade. The 5-year relative survival rate (RSR) increased to 44.3% that was previously 32.3% at the same time. However, between whites and blacks, an increase from 11 to 18 months was observed in the median survival differences. Between the low and high poverty groups, it was increased from 7 months to 12 months, respectively. CONCLUSIONS The incidence rate of RSR and EOC-specific individuals in the last forty years was improved. However, the survival rates among different races and SES differed over time.

Pre-operative radiomics model for prognostication in resectable pancreatic adenocarcinoma with external validation. Eur Radiol 2021; 32:2492-2505. [PMID: 34757450 DOI: 10.1007/s00330-021-08314-w] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2021] [Revised: 08/05/2021] [Accepted: 08/31/2021] [Indexed: 12/22/2022]
Abstract
OBJECTIVES In resectable pancreatic ductal adenocarcinoma (PDAC), few pre-operative prognostic biomarkers are available. Radiomics has demonstrated potential but lacks external validation. We aimed to develop and externally validate a pre-operative clinical-radiomic prognostic model. METHODS Retrospective international, multi-center study in resectable PDAC. The training cohort included 352 patients (pre-operative CTs from five Canadian hospitals). Cox models incorporated (a) pre-operative clinical variables (clinical), (b) clinical plus CT-radiomics, and (c) post-operative TNM model, which served as the reference. Outcomes were overall (OS)/disease-free survival (DFS). Models were assessed in the validation cohort from Ireland (n = 215, CTs from 34 hospitals), using C-statistic, calibration, and decision curve analyses. RESULTS The radiomic signature was predictive of OS/DFS in the validation cohort, with adjusted hazard ratios (HR) 2.87 (95% CI: 1.40-5.87, p < 0.001)/5.28 (95% CI 2.35-11.86, p < 0.001), respectively, along with age 1.02 (1.01-1.04, p = 0.01)/1.02 (1.00-1.04, p = 0.03). In the validation cohort, median OS was 22.9/37 months (p = 0.0092) and DFS 14.2/29.8 (p = 0.0023) for high-/low-risk groups and calibration was moderate (mean absolute errors 7%/13% for OS at 3/5 years). The clinical-radiomic model discrimination (C = 0.545, 95%: 0.543-0.546) was higher than the clinical model alone (C = 0.497, 95% CI 0.496-0.499, p < 0.001) or TNM (C = 0.525, 95% CI: 0.524-0.526, p < 0.001). Despite superior net benefit compared to the clinical model, the clinical-radiomic model was not clinically useful for most threshold probabilities. CONCLUSION A multi-institutional pre-operative clinical-radiomic model for resectable PDAC prognostication demonstrated superior net benefit compared to a clinical model but limited clinical utility at external validation. This reflects inherent limitations of radiomics for PDAC prognostication, when deployed in real-world settings. KEY POINTS • At external validation, a pre-operative clinical-radiomics prognostic model for pancreatic ductal adenocarcinoma (PDAC) outperformed pre-operative clinical variables alone or pathological TNM staging. • Discrimination and clinical utility of the clinical-radiomic model for treatment decisions remained low, likely due to heterogeneity of CT acquisition parameters. • Despite small improvements, prognosis in PDAC using state-of-the-art radiomics methodology remains challenging, mostly owing to its low discriminative ability. Future research should focus on standardization of CT protocols and acquisition parameters.

Disparities in Stage-Specific Guideline-Concordant Cancer-Directed Treatment for Patients with Pancreatic Adenocarcinoma. J Gastrointest Surg 2021; 25:2889-2901. [PMID: 33768427 DOI: 10.1007/s11605-021-04984-5] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 03/10/2021] [Indexed: 01/31/2023]
Abstract
BACKGROUND The utilization of cancer-directed treatment for patients with all stages of pancreatic cancer in the USA is unknown. This study sought to examine national practice patterns and identify patient, hospital, regional, and other factors associated with disparities in the use of guideline-concordant cancer-directed therapy. METHODS Patients diagnosed with PDAC between 2004 and 2015 were queried from the National Cancer Data Base. Standard of care cancer-directed treatment was defined as surgical resection plus chemotherapy or chemoradiation for patients with stage 1 and 2 disease, chemotherapy for patients with metastatic disease (stage 4), and chemotherapy with or without surgery or chemoradiation for patients with locally advanced stage 3 disease. RESULTS A total of 336,629 patients with stage 1 (n = 38,443, 11.4%), stage 2 (n = 93,923, 27.9%), stage 3 (n = 37,492, 11.1%), or stage 4 metastatic (n = 166,771, 49.5%) disease were identified. Adherence with stage-specific standard of care treatment occurred in only 45.3% (n = 152,560) of patients among the entire cohort and varied by stage of disease (stage 1: 14.6% vs. stage 2: 39.9% vs. stage 3: 67.6%, vs. stage 4: 50.9%). Older age (OR 0.95, 95%CI 0.94-0.95; p < 0.001), female sex (OR 0.94, 95%CI 0.943-0.97; p < 0.001), African Americans (OR 0.89, 95%CI 0.87-0.91; P < 0.001), and increasing comorbidity burden (Charlson-Deyo score ≥3: OR 0.52, 95%CI 0.50-0.55; P < 0.001) were associated with a lower likelihood of receiving stage-specific standard of care treatment. Conversely, treatment at a high-volume center (quartile 4: OR: 1.13, 95%CI 1.10-1.16; P < 0.001) and higher education level (OR 1.32, 95%CI 1.28-1.36; p < 0.001) was associated with higher likelihood of receiving stage-specific standard of care treatment. Patients who received standard of care treatment had a 47% lower risk of death compared with patients who did not receive standard of care treatment (HR 0.53, 95%CI 0.52-0.53; P < 0.001). CONCLUSION Pancreatic adenocarcinoma is a complex disease requiring a multi-disciplinary approach for optimal outcomes. Receipt of stage-specific standard of care treatment for PDAC is associated with improved long-term oncological outcomes, but is only achieved in less than half of patients. Further studies are needed to evaluate interventions to address these treatment disparities for patients with PDAC.

Abstract
There have been tremendous advances in the diagnosis and treatment of pancreatic cancer in the past decade, yet we are failing to achieve equitable outcomes for all patient populations. Disparities exist in the incidence, diagnosis, treatment, and outcomes of patients with pancreatic cancer. Inequities are based on racial and ethnic group, sex, socioeconomic status, and geography. To address disparities, future steps must focus on research methods, including collection and methodology, and policy measures, including access, patient tools, hospital incentives, and workforce diversity. Through these comprehensive efforts, we can begin to rectify inequitable care for treatment of patients with pancreatic cancer.

Abstract
Patients who develop one primary neoplasm are at increased risk for second cancers. Chemotherapeutic agents can result in DNA damage leading to clonal hematopoiesis, thereby causing myelodysplastic syndrome (MDS). Alkylating agents and topoisomerase inhibitors are most frequently implicated in therapy-related MDS. We report four patients with gastropancreatic malignancies (two with pancreatic adenocarcinoma and two with gastric adenocarcinoma) who developed MDS during or after the treatment of their primary gastrointestinal (GI) malignancies. Two of these patients were diagnosed with MDS during maintenance therapy with ramucirumab. To our knowledge, development of MDS in association with ramucirumab has not been previously reported in the literature. Our findings also suggest that with continued improvement in survival of patients with GI and pancreatic malignancies, more cases of treatment-related MDS might be identified.

Abstract
Pancreatic cancer (PaCa) is the fourth leading cause of cancer-related deaths in the United States, and the vast majority of these malignancies are pancreatic ductal adenocarcinomas (PDAC), but there is still a lack of early detection biomarkers for PaCa. Unlike linear RNAs, circRNAs form covalently closed continuous loops and can act as mammalian gene regulators. They may be diagnostic or predictive biomarkers for some tumors, also be novel potential therapeutic targets in different diseases. This review focuses on (1) the biogenesis of circRNAs, RNA binding proteins (RBPs) and complementary sequences of circRNAs; (2) the characteristics of circRNAs which allow them to interact with miRNAs; (3) the roles of circRNAs playing in the regulation of gene expression, cell behavior and cancer, and their potential role as novel biomarkers and therapeutic targets in pancreatic cancer.

Abstract
Little is known about the features and outcomes of Brazilian patients with pancreatic cancer. We sought to describe the socio-economic characteristics, patterns of health care access, and survival of patients diagnosed with malignant pancreatic tumors from 2000 to 2014 in São Paulo, Brazil. We included patients with malignant exocrine and non-classified pancreatic tumors according to the International Classifications of Disease (ICD)-O-2 and -O-3, diagnosed from 2000 to 2014, who were registered in the FOSP database. Prognostic factors for overall survival (OS) in the subgroup of patients with ductal or non-specified (adeno)carcinoma were evaluated using Cox proportional hazard model. The study population consists of 6855 patients. Median time from the first visit to diagnosis and treatment were 13 (Interquartile range [IQR] 4-30) and 24 (IQR 8-55) days, respectively. Both intervals were longer for patients treated in the public setting. Median OS was 4.9 months (95% confidence interval [95% CI] 4.7-5.2). Increasing age, male gender, lower educational level, treatment in the public setting, absence of treatment, advanced stage, and treatment from 2000 to 2004 were associated with inferior OS. From 2000-2004 to 2010-2014, no improvement in OS was seen for patients treated in the public setting. Survival of patients with malignant pancreatic tumors remains dismal. Socioeconomical variables, especially health care funding, are major determinants of survival. Further work is necessary to decrease inequalities in access to medical care for patients with pancreatic cancer in Brazil.

Abstract
Aim: To survey European physicians managing patients with metastatic pancreatic ductal adenocarcinoma (PDAC) and understand differences in baseline characteristics, diagnostic methods, symptoms and co-morbidities. Materials & methods: Patient record inclusion criteria were: ≥18 years old, metastatic PDAC diagnosis and completion of first-line treatment between July 2014 and January 2016. Records were grouped by patient age, gender and primary tumor location. Results: Records (n = 2565) were collected from nine countries. Baseline characteristics varied between subgroups. Computed tomography was the most frequently used diagnostic technique. Symptoms at diagnosis included abdominal and/or mid-back pain (72% of patients) and weight loss (61.5%). Co-morbidities varied with patient age. Conclusion: Greater awareness of symptoms, diagnostic methods and co-morbidities present at PDAC diagnosis may support better patient management decisions.

Abstract
Diabetes mellitus is a well-known risk factor for pancreatic cancer. We focused on hyperglycemia, a main feature of diabetes mellitus, and uncovered its effect on precancerous pancreatic intraepithelial neoplasia (PanIN) progression. In vivo induction of hyperglycemia with 100 mg/kg streptozotocin in KrasLSL G12DPdx1Cre (KP) mice promoted the PanIN formation and progression. Preconditioning with a high- or low-glucose medium for 28 days showed that a high-glucose environment increased cell viability and sphere formation in PANC-1, a Kras-mutant human pancreatic ductal adenocarcinoma cell line, and mPKC1, a Kras-mutant murine pancreatic cancer cell line. In contrast, no changes were observed in BxPC3, a Kras-wild-type human pancreatic cancer cell line. Orthotopic injection of mPKC1 into the pancreatic tails of BL6/J mice showed that cells maintained in high-glucose medium grew into larger tumors than did those maintained in low-glucose medium. Hyperglycemia strengthened the STAT3 phosphorylation, which was accompanied by elevated MYC expression in Kras-mutant cells. Immunohistochemistry showed stronger phosphorylated STAT3 (pSTAT3) and MYC staining in PanINs from diabetic KP mice than in those from euglycemic counterparts. STAT3 inhibition with 1 μM STAT3 inhibitor STATTIC in Kras-mutant pancreatic cell lines blocked the cell viability- and sphere formation-enhancing effects of the hyperglycemic environment and reversed the elevated pSTAT3 and MYC expression. MYC knockdown did not affect cell viability but did reduce sphere formation. No decrease in pSTAT3 expression was observed upon siMYC treatment. In conclusion, hyperglycemia, on a Kras-mutant background, aggravates the PanIN progression, which is accompanied by elevated pSTAT3 and MYC expression.

Abstract
PURPOSE Five percent to 9% of pancreatic ductal adenocarcinomas (PDACs) develop in patients with a germline BRCA1/2 or PALB2 (gBRCA/PALB2+) mutation. Phase IB data from a trial that used cisplatin, gemcitabine, and veliparib treatment demonstrated a high response rate (RR), disease control rate (DCR), and overall survival (OS) in this population. We designed an open-label, randomized, multicenter, two-arm phase II trial to investigate cisplatin and gemcitabine with or without veliparib in gBRCA/PALB2+ PDAC. PATIENTS AND METHODS Eligible patients had untreated gBRCA/PALB2+ PDAC with measurable stage III to IV disease and Eastern Cooperative Oncology Group performance status of 0 to 1. Treatment for patients in arm A consisted of cisplatin 25 mg/m2 and gemcitabine 600 mg/m2 intravenously on days 3 and 10; treatment for patients in arm B was the same as that for patients in arm A, and arm A also received veliparib 80 mg orally twice per day on days 1 to 12 cycled every 3 weeks. The primary end point was RRs of arm A and arm B evaluated separately using a Simon two-stage design. Secondary end points were progression-free survival, DCR, OS, safety, and correlative analyses. RESULTS Fifty patients were evaluated by modified intention-to-treat analysis. The RR for arm A was 74.1% and 65.2% for arm B (P = .55); both arms exceeded the prespecified activity threshold. DCR was 100% for arm A and 78.3% for arm B (P = .02). Median progression-free survival was 10.1 months for arm A (95% CI, 6.7 to 11.5 months) and 9.7 months for arm B (95% CI, 4.2 to 13.6 months; P = .73). Median OS for arm A was 15.5 months (95% CI, 12.2 to 24.3 months) and 16.4 months for arm B (95% CI, 11.7 to 23.4 months; P = .6). Two-year OS rate for the entire cohort was 30.6% (95% CI, 17.8% to 44.4%), and 3-year OS rate was 17.8% (95% CI, 8.1% to 30.7%). Grade 3 to 4 hematologic toxicities for arm A versus arm B were 13 (48%) versus seven (30%) for neutropenia, 15 (55%) versus two (9%) for thrombocytopenia, and 14 (52%) versus eight (35%) for anemia. CONCLUSION Cisplatin and gemcitabine is an effective regimen in advanced gBRCA/PALB2+ PDAC. Concurrent veliparib did not improve RR. These data establish cisplatin and gemcitabine as a standard approach in gBRCA/PALB2+ PDAC.

CPI-613 rewires lipid metabolism to enhance pancreatic cancer apoptosis via the AMPK-ACC signaling. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2020; 39:73. [PMID: 32345326 PMCID: PMC7187515 DOI: 10.1186/s13046-020-01579-x] [Citation(s) in RCA: 50] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/31/2019] [Accepted: 04/22/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Pancreatic cancer remains one of the most rapidly progressive and deadly malignancies worldwide. Current treatment regimens only result in small improvements in overall survival for patients with this cancer type. CPI-613 (Devimistat), a novel lipoate analog inhibiting mitochondrial metabolism, shows the new hope for pancreatic cancer treatment as an efficient and well-tolerated therapeutic option treated alone or in combination with chemotherapy. METHODS Pancreatic cancer cells growing in planar 2D cultures and 3D scaffold were used as research platforms. Cell viability was measured by MTT and alamarBlue, and apoptosis was assessed by JC-1 staining and flow cytometry with Annexin V-FITC/PI staining. The mechanism behind CPI-613 action was analyzed by western blot, transmission electron microscopy, and lipolysis assay kits, in the presence or absence of additional signaling pathway inhibitors or gene modifications. RESULTS CPI-613 exhibits anticancer activity in pancreatic cancer cells by triggering ROS-associated apoptosis, which is accompanied by increased autophagy and repressed lipid metabolism through activating the AMPK signaling. Intriguingly, ACC, the key enzyme modulating lipid metabolism, is identified as a vital target of CPI-613, which is inactivated in an AMPK-dependent manner and influences apoptotic process upon CPI-613. Blockade or enhancement of autophagic process does not increase or blunt apoptosis to CPI-613, but inhibition of the AMPK-ACC signaling significantly attenuates apoptosis induced by CPI-613, suggesting CPI-613-mediated lipid metabolism reduction contributes to its cytotoxicity in pancreatic cancer cells. CONCLUSIONS These findings explore the critical role of lipid metabolism in apoptosis, providing new insights into the AMPK-ACC signaling axis in crosstalk between lipid metabolism and apoptosis in CPI-613 treatment.

Abstract
Background: Pancreatic ductal adenocarcinoma (PDAC) is a highly malignant disease and has the worst prognosis and survival rate. TUBA1C is a microtubule component implicated in multiple cancers, however, the clinical significance and biological functions of TUBA1C in the progression of PDAC remain unexplored. Methods: The Cancer Genome Atlas (TCGA) and Gene Expression Profiling Interactive Analysis (GEPIA) data were employed to detect the TUBA1C mRNA expression and the relation between TUBA1C expression and overall survival (OS) in PDAC. Then, bioinformatic analysis was employed to determine the potential pathway and genes related to TUBA1C. Human pancreatic cancer tissue and adjacent non-tumor tissues samples were detected by immunochemistry (IHC) staining, and the correlation between TUBA1C expression and the clinicopathological features were investigated. Meanwhile, TUBA1C expression in PDAC cell lines was evaluated by western blotting. Furthermore, functional assays including cell viability, apoptosis, cell cycle, transwell assay, wound healing assay, and a xenograft tumor model were performed to determine the oncogenic role of TUBA1C in PDAC, respectively. Results: TUBA1C was overexpressed in the PDAC tissues and cells. IHC analysis showed that the TUBA1C overexpression was associated with short OS. Bioinformatic analysis indicated that TUBA1C overexpression was mainly associated with cell cycle regulation. The downregulation of TUBA1C significantly suppressed cell proliferation, induced cell apoptosis and cycle arrest, and inhibited invasion and migration in PDAC cells. Furthermore, TUBA1C downregulation also inhibited tumor growth in vivo. Conclusion: These findings suggested that TUBA1C downregulation suppressed PDAC aggressiveness via cell cycle pathway and that TUBA1C may serve as a potential prognostic marker for PDAC therapy.

Abstract
Background Pancreatic cancer (pcc) is one of the most lethal types of cancer, and surgery remains the optimal treatment modality for patients with resectable tumours. The objective of the present study was to examine and compare trends in the survival rate based on treatment modality in patients with pcc. Methods This population-based retrospective analysis included all patients with known-stage pcc in Ontario between 2007 and 2015. Flexible parametric models were used to conduct the survival analysis. Survival rates were calculated based on treatment modality, while adjusting for patient- and tumour-specific covariates. Results The study included 6437 patients. We found no noticeable improvement in survival for patients with stage iii or iv tumours; however, for stage i disease, the 1-, 2-, and 5-year survival rates increased over time to 81% from 51%, to 71% from 35%, and to 61% from 22% respectively. Most improvements were seen for surgical modalities, with 2-year survivals increasing to 89% from 65% for distal pancreatectomy (dp) without radiation (rt) or chemotherapy (ctx), to 65% from 37% for dp plus rt or ctx, to 60% from 44% for Whipple-only, and to 50% from 36% for Whipple plus rt or ctx. Lastly, 5-year survival improved to 81% from 52% for dp only, to 41% from 12% for dp plus rt or ctx, to 49% from 25% for Whipple-only, and to 26% from 12% for Whipple plus rt or ctx. Conclusions Most cases of pcc continue to be diagnosed at a late stage, with poor short-term and long-term prognoses. After adjustment for patient age, sex, and year of diagnosis, the survival for stage i tumours and for surgical modalities increased over time. Further research is needed to identify the reasons for improvement in survival during the study period.

Abstract
Background Pancreatic ductal adenocarcinoma (PDAC) is considered as one of the most aggressive cancers lacking efficient early detection biomarkers. Circulating miRNAs are now being considered to have potency to be used as diagnostic and prognostic biomarkers in different diseases as well as cancers. In case of cancer, a fraction of the circulating miRNAs is actually derived from the tumour tissue. This fraction would function as stable biomarker for the disease and also would contribute to the understanding of the disease development. There are not many studies exploring this aspect in pancreatic cancer and even there is not much overlap of results between existing studies. Methods In order to address that gap, we performed a miRNA microarray analysis to identify differentially expressed circulating miRNAs between PDAC patients and normal healthy individuals and also found two more similar datasets to perform a meta-analysis using a total of 182 PDAC patients and 170 normal, identifying a set of miRNAs significantly altered in patient serum. Next, we found five datasets studying miRNA expression profile in tumour tissues of PDAC patients as compared to normal pancreas and performed a second meta-analysis using data from a total of 183 pancreatic tumour and 47 normal pancreas to detect significantly deregulated miRNAs in pancreatic carcinoma. Comparison of these two lists and subsequent search for their target genes which were also deregulated in PDAC in inverse direction to miRNAs was done followed by investigation of their role in disease development. Results We identified 21 miRNAs altered in both pancreatic tumour tissue and serum. While deciphering the functions of their target genes, we characterized key miR-Gene interactions perturbing the biological pathways. We identified important cancer related pathways, pancreas specific pathways, AGE-RAGE signaling, prolactin signaling and insulin resistance signaling pathways among the most affected ones. We also reported the possible involvement of crucial transcription factors in the process. Conclusions Our study identified a unique meta-signature of 21 miRNAs capable of explaining pancreatic carcinogenesis and possibly holding the potential to act as biomarker for the disease detection which could be explored further.

Abstract
Importance Postoperative morbidity associated with pancreaticoduodenectomy (PD) for pancreatic adenocarcinoma (PA) remains as high as 70%. However, to our knowledge, few studies have examined quality of life in this patient population. Objective To identify symptom burden and trajectories and factors associated with high symptom burden following PD for PA. Design, Setting, and Participants This population-based cohort study of patients undergoing PD for PA diagnosed between 2009 and 2015 linked population-level administrative health care data to routinely prospectively collected Edmonton Symptom Assessment System (ESAS) scores from 2009 to 2015, with a data analysis undertaken in 2018. Exposures Baseline characteristics, including age, sex, income quintile, rurality, immigration status, and comorbidity burden, as well as treatment characteristics, including year of surgery and receipt of chemotherapy. Main Outcome and Measures The outcome of interest was moderate to severe symptoms (defined as ESAS ≥4) for anxiety, depression, drowsiness, lack of appetite, nausea, pain, shortness of breath, tiredness, and impaired well-being. The monthly prevalence of moderate to severe symptoms was presented graphically for each symptom. Multivariable regression models identified factors associated with the reporting of moderate to severe symptoms. Results We analyzed 6058 individual symptom assessments among 615 patients with PA who underwent resection (285 women [46.3%]) with ESAS data. Tiredness (443 [72%]), impaired well-being (418 [68%]), and lack of appetite (400 [65%]) were most commonly reported as moderate to severe. The proportion of patients with moderate to severe symptoms was highest immediately after surgery (range, 14%-66% per symptom) and decreased over time, stabilizing around 3 months (range, 8%-42% per symptom). Female sex, higher comorbidity, and lower income were associated with a higher risk of reporting moderate to severe symptoms. Receipt of adjuvant chemotherapy was not associated with the risk of moderate to severe symptoms. Conclusions and Relevance There is a high prevalence of symptoms following PD for PA, with improvement over the first 3 months following surgery. In what to our knowledge is the largest cohort reporting on symptom burden for this population, we have identified factors associated with symptom severity. These findings will aid in managing patients' perioperative expectations and designing strategies to improve targeted symptom management.

Abstract
Purpose: Pancreatic cancer remains a major health concern; in the next 2 years, it will become the second leading cause of cancer deaths in the United States. Health disparities in the treatment of pancreatic cancer exist across many disciplines, including race and ethnicity, socioeconomic status (SES), and insurance. This narrative review discusses what is known about these disparities, with the goal of highlighting targets for equity promoting interventions. Methods: We performed a narrative review of health disparities in pancreatic cancer spanning greater than ten areas, including epidemiology, treatment, and outcome, using the PubMed NIH database from 2000 to 2019 in the Unites States. Results: African Americans (AAs) tend to present at diagnosis with later stage disease. AAs and Hispanics have lower rates of surgical resection, are more likely to be treated at low volume hospitals, and often experience higher rates of morbidity and mortality compared to white patients, although control for confounders is often limited. Insurance and SES also factor into the delivery of treatment for pancreatic cancer. Conclusion: Disparities by race and SES exist in the diagnosis and treatment of pancreatic cancer that are largely driven by race and SES. Improved understanding of underlying causes could inform interventions.

Abstract
BACKGROUND Pain is a common debilitating symptom in pancreatic adenocarcinoma. This cohort study examined the use of, and factors associated with, pain-directed interventions for a high pain score in patients with non-curable pancreatic adenocarcinoma. METHODS Administrative databases were linked and patients with non-resected pancreatic adenocarcinoma diagnosed between 2010 and 2016, who reported one or more Edmonton Symptom Assessment System (ESAS) score, were identified. A high pain score was defined as an ESAS score of at least 4. Outcomes were pain-directed interventions: opiates (in patients aged 65 years or more with universal drug coverage), nerve block and radiation therapy for a high pain score. Reduction in pain score of at least 1 point after pain-directed intervention was also evaluated. Modified Poisson regression was used to examine factors associated with pain-directed intervention. RESULTS Among 2623 patients with a median age of 67 years, 1223 (46·6 per cent) were women, and 1621 (61·8 per cent) reported a high pain score at a median of 38 days after diagnosis. Of those with a high pain score, 75·6 per cent (688 of 910) received opiates, 13·5 per cent (219 of 1621) radiation and 1·2 per cent (19 of 1621) nerve block. The pain score decreased in 62·1 per cent of patients after administration of opiates, 73·4 per cent after radiation and all patients after nerve block. In multivariable analysis, no patient factor (age, sex, co-morbidity burden, rurality, income quintile) was associated with receipt of non-opiate pain-directed intervention for a high pain score. In patients aged at least 65 years, advanced age was associated with lower odds of opiate use. CONCLUSION Opiates are the most common pain-directed intervention for non-curable pancreatic adenocarcinoma, whereas radiation therapy and nerve blocks are seldom used. The lack of association between pain-directed interventions and patient factors points toward practice-driven patterns.

Abstract
Background::Human tumor cells lines and tumor samples overexpress the neurokinin-1 receptor (NK-1R). Substance P (SP), after binding to NK-1Rs, induces tumor cell proliferation, an antiapoptotic effect and promotes angiogenesis and the migration of cancer cells for invasion and metastasis.Methods: :In contrast, NK-1R antagonists block the previous pathophysiological actions mediated by SP. These antagonists promote the death of tumor cells by apoptosis. Peptide and non-peptide NK-1R antagonists have been reported.Results: :Peptide NK-1R antagonists show chemical modifications of the SP molecule (L-amino acids being replaced by D-amino acids), whereas non-peptide NK-1R antagonists include numerous compounds with different chemical compositions while showing similar stereochemical features (affinity for the NK- 1R). Currently, there are more than 300 NK-1R antagonists.Conclusion::In combination therapy with classic cytostatics, NK-1R antagonists have additive or synergic effects and minimize the side-effects of cytostatics. The effect of NK-1R antagonists as broad-spectrum anticancer drugs is reviewed and the use of these antagonists for the treatment of cancer is suggested.

Electrochemotherapy Causes Caspase-Independent Necrotic-Like Death in Pancreatic Cancer Cells. Cancers (Basel) 2019; 11:cancers11081177.

Abstract
Pancreatic cancer represents a major challenge in oncology. Poor permeability of the pancreas and resistance to currently available therapies are impediments to improved patient survival. By transiently increasing cell membrane porosity and increasing drug uptake, Electrochemotherapy (ECT) has the potential to overcome these issues. In this study, we have evaluated the response of human and murine pancreatic cancer cells, in vitro, to electroporation in combination with Bleomycin, Cisplatin, or Oxaliplatin (ECT). The cytotoxic actions of all three drugs are potentiated when combined with electroporation in these cells. The biochemical and morphological changes post ECT are associated with immunogenic cell death that occurs with necroptosis rather than apoptosis. Moreover, ECT-induced cell death is rescued by Nec-1 suggesting that necroptosis may play a role in cell death mediated by cancer therapies.

Abstract
Pancreatic cancer carries a poor prognosis and given insidious symptoms has often metastasized at the time of presentation. Common sites of metastasis involve liver, lungs, regional lymph nodes, or peritoneum. Colonic metastasis is rare, with only a few previous descriptions in the literature. We report a case of a 91-year-old woman with presumed pancreatic adenocarcinoma based on pathology and imaging, with colonic metastasis presenting as colonic obstruction.

Abstract
BACKGROUND Pancreatic cancer is the fourth leading cause of cancer-related mortality in the United States. Descriptive epidemiology of pancreatic cancer in South Dakota has not been studied before. MATERIALS AND METHODS All cases of pancreatic cancer reported to the SD Cancer Registry between January 2005 and December 2014 were included in the study. Variables collected included demographics, geographical location including county of residence and zip codes, date of diagnosis, date of last contact or follow-up, size and location of the tumor, grade of the tumor, diagnostic modality as well as therapeutic interventions. Log rank test was used to compare survival curves. Kaplan-Meier product limit estimates were provided. Data was analyzed using SAS 9.1.4 software. RESULTS One thousand sixty-four cases of pancreatic cancer were reported. Median age was 73 years. Cumulative age-adjusted incidence rate for pancreatic cancer for 2005-2014 was 11.1. Cumulative age-adjusted mortality rate for pancreatic cancer for 2005-2014 was 10.2. Almost half of these patients had distant metastasis at the time of presentation (n = 536; 50.4%). Overall, median survival was 5 months. Median survival for patients under the age of 60 years was 9.5 months as opposed to median survival for patients 60 years or older which was 3.9 months. Median survival of patients with well-differentiated, moderately differentiated, and poorly differentiated tumors, was 20.8 months, 8.2 months and 6.3 months respectively (p value = 0.0017). CONCLUSION Incidence of pancreatic cancer in South Dakota is similar to the national trends in the United States. Age at presentation, location of tumor in pancreas, and biological behavior of tumor were all predictors of survival in patients with pancreatic cancer.

Abstract
OBJECTIVES Pancreatic cancer is a highly lethal disease predominantly affecting older patients. Characterization of outcomes in these patients may help optimise treatment decisions. The global, phase 3 NAPOLI-1 trial (NCT01494506) demonstrated an overall survival (OS) benefit with liposomal irinotecan and 5-flurouracil/leucovorin (nal-IRI + 5-FU/LV) versus 5-FU/LV. This subgroup analysis explored impact of age on outcomes in NAPOLI-1 patients, and nal-IRI + 5-FU/LV efficacy and safety in older patients. MATERIALS AND METHODS This exploratory, post-hoc analysis of the NAPOLI-1 trial included patients aged ≥eighteen years (no upper limit) with metastatic pancreatic adenocarcinoma that had progressed on gemcitabine-based therapy. Patients were stratified by age (cut-offs at 65, 70, and 75 years); OS and progression-free survival (PFS) were estimated by Kaplan-Meier analysis. RESULTS Of 417 randomized patients, 192 (46%), 110 (26%) and 43 (10%) were aged ≥65, ≥70 and ≥ 75 years, respectively. Mortality risk and risk of disease progression were similar in older and younger patients independent of treatment (HRs for median [m]OS/mPFS comparisons were 0.88/0.95 [<65 versus ≥65 years], 0.89/0.88 [<70 versus ≥70 years] and 1.04/0.98 [<75 versus ≥75 years]; P > .25). Reduced mortality/morbidity risk with nal-IRI + 5-FU/LV in older subgroups was in line with the wider population. No additional toxicities with nal-IRI + 5-FU/LV were observed in older patients: 86% of patients ≥75 years versus 69% <75 years required a dose delay or reduction due to toxicities (43% versus 32% dose reductions). DISCUSSION Results suggest that older patients with metastatic pancreatic adenocarcinoma that progressed on prior gemcitabine-based treatment can benefit from second-line therapy, supporting nal-IRI + 5-FU/LV treatment in older patients.

Abstract
BACKGROUND Pancreatic cancer is one of the main cancer-related causes of death in developed countries, and one of the most lethal malignant neoplasms. This type of cancer is classified as the ninth most frequent in the world. OBJECTIVE Analyze temporal trends for pancreatic cancer in Brazil in the period 2000-2014 and calculate mortality projections for the period 2015-2029. METHODS Ecological study, with temporal series, based on information provided by the Brazilian Mortality Information System. Analysis included deaths due to pancreatic malignant neoplasms in Brazil in the period 2000-2014, and analyzed according to sex, age group and Brazilian geographic regions. Projections were made until 2029 in five-year periods, calculated in Nordpred (within the R software). Mortality trends were analyzed by Joinpoint regression. RESULTS Between 2000 and 2014, there were 112,533 deaths due to pancreatic cancer in Brazil. Age-standardised rates was 5.1 deaths/100,000 men and 3.81 deaths/100,000 women. The highest rates were registered for the Midwest region, for both genders. Projections indicated that for the five-year period 2025-2029 there will be increased mortality rates for men in the Northeast and Midwest regions. Joinpoint analysis for Brazil did not reveal significant increases for women (APC=0.4%; 95% CI: -0.2; 1.0), however, there was a significant increasing mortality trend for men (APC= 3.7%; 95% CI: 0.6-7.0) in the period 2000-2004, followed by a stable period, an then another period of significant increases after 2010. These figures are mostly explained by variations in the Brazilian demographic structure. CONCLUSION Pancreatic cancer mortality is unequally distributed across Brazilian regions and genders, and during the next two decades the differences will be accentuated.

Abstract
BACKGROUND Pancreatic adenocarcinoma rarely metastasizes to the brain, and clinical features of brain metastasis in such cases remain elusive. To the best of our knowledge, only 21 cases of brain metastasis from pancreatic adenocarcinoma have been previously reported in the English language literature. CASE DESCRIPTION A 61-year-old woman was diagnosed with pancreatic adenocarcinoma and began chemotherapy 1 year 4 months before the current admission. Three days before the current admission, she developed acute dysarthria. She was referred to a cancer center, where neuroradiologic examination showed multiple metastatic brain tumors, including a 30-mm-diameter tumor in the right cerebellar region. She was transferred to our institute. Three days after admission, she developed sudden-onset disturbance of consciousness and left hemiparesis. Computed tomography and magnetic resonance imaging of the head showed that the metastatic lesions had increased in size with development of intratumoral hemorrhage and obstructive hydrocephalus. She underwent urgent removal of the tumor in the cerebellum. Obstructive hydrocephalus was relieved, and her consciousness improved immediately after surgery. She was transferred to the palliative care unit of the cancer center and died under hospice care 3 weeks after surgery. CONCLUSIONS This case demonstrates that brain metastases from pancreatic adenocarcinoma can enlarge suddenly and simultaneously with intratumoral hemorrhage even without coagulation disorders, resulting in neurologic deterioration in a short time. Surgical resection of metastatic brain lesions from pancreatic adenocarcinoma has an extremely limited role, but such treatment can remove neurologic symptoms and temporarily improve the patient's quality of life in selected cases.

Abstract
BACKGROUND AND OBJECTIVES To compare the ability of multidetector computed tomography (MDCT) and contrast-enhanced EUS to discriminate chronic pancreatitis (CP) from pancreatic ductal adenocarcinoma (PDAC). SUBJECTS AND METHODS A total of 215 patients (age: 62 ± 15 years, sex: f/m 80/135) were included in this retrospective study. All patients were examined by conventional endoscopic B-mode and contrast-enhanced high mechanical index EUS (CEHMI-EUS). CELMI-EUS was performed in 159 patients and endoscopic sonoelastography (ESE) in 210 patients. MDCT was carried out in 131 patients as part of their clinical work-up. Radiological reports were retrospectively analyzed. Final diagnosis was achieved by biopsy and evaluation of cytological specimens collected was performed by EUS-FNA, surgery, or follow-up of 12 months or more in patients with benign findings. In a subgroup of 100 patients, all diagnostic five methods were performed, and head-to-head analysis was performed. RESULTS Sensitivity and specificity for MDCT were 89% and 70% and for CEHMI-EUS were 96% and 91%, respectively. Sensitivities and specificities for EUS were 92% and 63% for B-Mode EUS, 96% and 38% for ESE, and 82% and 76% for CELMI-EUS, respectively. In the head-to-head analysis, each modality had shown lower numbers for specificity than shown in the overall group analysis because of high drop-out rate. EUS-FNA for PDAC had a sensitivity of 96% and a specificity of 100%. CONCLUSIONS Contrast-enhanced EUS is a reliable tool in discriminating PDAC from CP.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is a highly malignant solid tumor with a dismal prognosis. The stroma component makes up to 90% of the tumor mass and is thought to be one of the main reasons for the tumor's high chemoresistance. Cancer associated fibroblasts (CAFs) have previously been identified to be the key stromal players. This is the first time we provide detailed in vitro experiments investigating tumor-stromal interactions when exposed to three well-known chemotherapeutic agents. METHODS Monocultures, indirect and direct co-cultures of two PDAC cell lines (AsPC and Panc-1) and six primary patients derived CAFs were treated with gemcitabine, nab-paclitaxel and the γ-secretase-inhibitor (GSI) DAPT. The cell viability of each component was measured with XTT. Finally, IL-6 concentrations of the supernatants were analyzed. RESULTS On the contrary to PDAC cell lines, CAF monocultures hardly responded to any treatment which suggested that stroma (CAFs) itself is more resistant to standard chemo-treatments than the epithelial cancer cells. Moreover, only a weak chemotherapeutic response was observed in direct co-cultures of cancer cells with CAFs. A change in the morphology of direct co-cultures was accompanied with the chemoresistance. CAFs were observed to build cage-like structures around agglomerates of tumor cells. High levels of IL-6 were also associated with a reduced response to therapy. Indirect co-cultures make the tumor-stromal interaction more complex. CONCLUSIONS CAFs are highly chemoresistant. Direct cell-cell contact and high levels of IL-6 correlate with a high chemoresistance.
