Abstract
INTRODUCTION Pancreatic cancer is a significant public health concern and a leading cause of cancer-related deaths worldwide. This study aimed to investigate pancreatic cancer mortality trends and disparities in the United States (US) from 1999 to 2020. METHODS Data were obtained from the Centers for Disease Control (CDC) Wide-Ranging Online Data for Epidemiologic Research database. Mortality rates were age-adjusted and standardized to the year 2000 US population. Joinpoint regression was used to analyze temporal trends in age-adjusted mortality rates (AAMRs) by sociodemographic and geographic variables. RESULTS Between 1999 and 2020, pancreatic cancer led to a total of 810,628 deaths in the US, an average mortality of nearly 39,000 deaths per year. The AAMR slightly increased from 10.6 in 1999 to 11.1 in 2020, with an associated annual percent change (APC) of 0.2. Mortality rates were highest among individuals aged 65 and older. Black individuals experienced the highest overall pancreatic cancer-related AAMR at 13.8. Despite this, Black individuals experienced a decreasing mortality trend over time (APC -0.2) while White individuals experienced an increasing trend in mortality (APC 0.4). Additionally, individuals residing in rural areas experienced steeper rates of mortality increase than those living in urban areas (APC 0.6 for rural vs -0.2 for urban). White individuals in urban and rural populations experienced an increase in mortality, while Black individuals in urban environments experienced a decrease in mortality, and Black individuals in rural environments experienced stable mortality trends. CONCLUSIONS Mortality from pancreatic cancer continues to increase in the US, with racial and regional disparities identified in minorities and rural-dwelling individuals. These disparate findings highlight the importance of ongoing efforts to understand and address pancreatic cancer treatment and outcomes disparities in the US, and future studies should further investigate the underlying etiologies of these disparities and potential for novel therapies to reduce the mortality.

Abstract
AIMS To determine the relationship of diabetes with pancreatic cancer incidence among African American and Whites of similar socio-economic status. METHODS Using the Southern Community Cohort Study, we conducted a follow-up during 2002-2015 of pancreatic cancer incidence of 73,378 mostly low-income participants aged 40-79 years; 15,913 reported diabetes at baseline. Multivariable Cox analysis controlling for sex, family history of pancreatic cancer, BMI, smoking status, alcohol consumption, education, income and other important covariates, and with age as the timescale was used. RESULTS Totally, 265 incident pancreatic cancer cases were observed. Pancreatic cancer risk was increased among those with diabetes (HR 1.54, CI 1.16-2.05), with similar increases among African Americans (HR 1.51, CI 1.08-2.11) and Whites (HR 1.78, CI 1.00-3.16). No trend in risk was observed for diabetes duration among those with diabetes, with HRs of 1.39 (0.91-2.11), 2.31 (1.51-3.54) and 1.23 (0.80-1.89) for <5, 5-9 and 10+ years duration, respectively. African Americans were at increased risk of pancreatic cancer (HR = 1.40, 95% CI 1.05-1.87), which persisted after adjusting for diabetes (HR 1.36, CI 1.02-1.81). The effect sizes for other pancreatic cancer risk factors with pancreatic cancer were similar by diabetes status, although a stronger association with low BMI was evident among those with diabetes. CONCLUSIONS Diabetes increases pancreatic cancer risk similarly among African Americans and Whites in this Southern U.S. COHORT

Simulating the healthcare workforce impact and capacity for pancreatic cancer care in Victoria: a model-based analysis. BMC Health Serv Res 2024; 24:239. [PMID: 38395852 PMCID: PMC10893744 DOI: 10.1186/s12913-024-10722-9] [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: 06/09/2023] [Accepted: 02/14/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND The incidence of pancreatic cancer is rising. With improvements in knowledge for screening and early detection, earlier detection of pancreatic cancer will continue to be more common. To support workforce planning, our aim is to perform a model-based analysis that simulates the potential impact on the healthcare workforce, assuming an earlier diagnosis of pancreatic cancer. METHODS We developed a simulation model to estimate the demand (i.e. new cases of pancreatic cancer) and supply (i.e. the healthcare workforce including general surgeons, medical oncologists, radiation oncologists, pain medicine physicians, and palliative care physicians) between 2023 and 2027 in Victoria, Australia. The model compares the current scenario to one in which pancreatic cancer is diagnosed at an earlier stage. The incidence of pancreatic cancer in Victoria, five-year survival rates, and Victoria's population size were obtained from Victorian Cancer Registry, Cancer Council NSW, and Australian Bureau of Statistics respectively. The healthcare workforce data were sourced from the Australian Government Department of Health and Aged Care's Health Workforce Data. The model was constructed at the remoteness level. We analysed the new cases and the number of healthcare workforce by profession together to assess the impact on the healthcare workforce. RESULTS In the status quo, over the next five years, there will be 198 to 220 stages I-II, 297 to 330 stage III, and 495 to 550 stage IV pancreatic cancer cases diagnosed annually, respectively. Assuming 20-70% of the shift towards pancreatic cancer's earlier diagnosis (shifting from stage IV to stages I-II pancreatic cancer within one year), the stages I-II cases could increase to 351 to 390 or 598 to 665 per year. The shift to early diagnosis led to substantial survival gains, translating into an additional 284 or 795 out of 5246 patients with pancreatic cancer remaining alive up to year 5 post-diagnosis. Workforce supply decreases significantly by the remoteness levels, and remote areas face a shortage of key medical professionals registered in delivering pancreatic cancer care, suggesting travel necessities by patients or clinicians. CONCLUSION Improving the early detection and diagnosis of pancreatic cancer is expected to bring significant survival benefits, although there are workforce distribution imbalances in Victoria that may affect the ability to achieve the anticipated survival gain.

Abstract
BACKGROUND The impact of neighborhood deprivation on outcomes in patients with pancreatic ductal adenocarcinoma (PDAC) is not well-described and represents an area to improve disparities. METHODS We retrospectively queried our prospectively maintained database of patients with PDAC (2014-2022). Patients were grouped by Area Deprivation Index (ADI) and rural-urban commuting area (RUCA) codes. Cox proportional hazards models and logistic regressions were used to investigate effect on overall survival (OS) and adjuvant therapy administration. RESULTS 536 patients were included. High ADI patients (more disadvantaged, n = 184) were more likely to identify as non-Hispanic Black (17.9% vs. 4.8%, p < 0.01) and were more likely to be from rural areas (49.5% vs. 18.5%, p < 0.01). High ADI was independently associated with decreased OS (HR (95% CI): 1.31 (1.01-1.69), p = 0.04). Urban high ADI patients were 3.5 times more likely to receive adjuvant therapy than rural high ADI patients (OR [95% CI]: 3.48 [1.26-9.61], p = 0.02). CONCLUSION Patients from the most disadvantaged neighborhoods have decreased OS. Access to adjuvant therapy likely contributes to this disparity in rural areas. Investigation into sources of this OS disparity and identification of barriers to adjuvant therapy will be crucial to improve outcomes in underserved patients with PDAC.

Abstract
Pancreatic cancer is a highly malignant tumor known for its extremely low survival rate. The combination of genetic disorders within pancreatic cells and the tumor microenvironment contributes to the emergence and progression of this devastating disease. Extensive research has shed light on the nature of the microenvironmental cells surrounding the pancreatic cancer, including peripheral nerves and immune cells. Peripheral nerves release neuropeptides that directly target pancreatic cancer cells in a paracrine manner, while immune cells play a crucial role in eliminating cancer cells that have not evaded the immune response. Recent studies have revealed the intricate interplay between the nervous and immune systems in homeostatic condition as well as in cancer development. In this review, we aim to summarize the function of nerves in pancreatic cancer, emphasizing the significance to investigate the neural-immune crosstalk during the advancement of this malignant cancer.

Abstract
OBJECTIVE To understand the mediating effect of socioeconomic factors on the association between residential segregation and racial disparities in pancreatic cancer (PC). BACKGROUND Black patients with PC present at a later stage and have worse mortality than White patients. These disparities have been explained by the level of residential segregation. METHODS Data were obtained from Surveillance, Epidemiology, and End-Results (SEER) and included all Black and White patients who were diagnosed with PC between 2005 and 2015. The primary exposure variable was the Index of Dissimilarity, a validated measure of segregation. County-level socioeconomic variables from the US Census were assessed as mediators. The primary outcomes were advanced stage at diagnosis, surgical resection for localized disease, and overall mortality. Generalized structural equation modeling was used to assess the mediation of each of the socioeconomic variables. RESULTS Black patients in the highest levels of segregation saw a 12% increased risk [relative risk=1.12; 95% confidence interval (CI): 1.08, 1.15] of presenting at an advanced stage, 11% decreased likelihood of undergoing surgery (relative risk=0.89; 95% CI: 0.83, 0.94), and 8% increased hazards of death (hazard ratio=1.08; 95% CI: 1.03, 1.14) compared with White patients in the lowest levels. The Black share of the population, insurance status, and income inequality mediated 58% of the total effect on the advanced stage. Poverty and Black income immobility mediated 51% of the total effect on surgical resection. Poverty and Black income immobility mediated 50% of the total effect on overall survival. CONCLUSIONS These socioeconomic factors serve as intervention points for legislators to address the social determinants inherent to the structural racism that mediate poor outcomes for Black patients.

Abstract
BACKGROUND Screening options for pancreatic ductal adenocarcinoma (PDAC) are limited. New-onset type 2 diabetes (NoD) is associated with subsequent diagnosis of PDAC in observational studies and may afford an opportunity for PDAC screening. We evaluated this association using a large administrative database. METHODS Patients were identified using claims data from the OptumLabs® Data Warehouse. Adult patients with NoD diagnosis were matched 1:3 with patients without NoD using age, sex and chronic obstructive pulmonary disease (COPD) status. The event of PDAC diagnosis was compared between cohorts using the Kaplan-Meier method. Factors associated with PDAC diagnosis were evaluated with Cox's proportional hazards modeling. RESULTS We identified 640 421 patients with NoD and included 1 921 263 controls. At 3 years, significantly more PDAC events were identified in the NoD group vs control group (579 vs 505; P < 0.001). When controlling for patient factors, NoD was significantly associated with elevated risk of PDAC (HR 3.474, 95% CI 3.082-3.920, P < 0.001). Other factors significantly associated with PDAC diagnosis were increasing age, increasing age among Black patients, and COPD diagnosis (P ≤ 0.05). CONCLUSIONS NoD was independently associated with subsequent diagnosis of PDAC within 3 years. Future studies should evaluate the feasibility and benefit of PDAC screening in patients with NoD.

Abstract
OBJECTIVE The aim of this study was to quantify the contributions of socioeconomic, psychosocial, behavioral, reproductive, and neighborhood exposures in young adulthood to Black-White differences in incident obesity. METHODS In the Coronary Artery Risk Development in Young Adults (CARDIA) study, 4488 Black or White adults aged 18 to 30 years without obesity at baseline (1985-1986) were followed over 30 years. Sex-specific Cox proportional hazard models were used to estimate Black-White differences in incident obesity. Models were adjusted for baseline and time-updated indicators. RESULTS During follow-up, 1777 participants developed obesity. Black women were 1.87 (95% CI: 1.63-2.13) times more likely and Black men were 1.53 (95% CI: 1.32-1.77) times more likely to develop obesity than their White counterparts after adjusting for age, field center, and baseline BMI. Baseline exposures explained 43% of this difference in women and 52% in men. Time-updated exposures explained more of the racial difference in women but less for men, compared with baseline exposures. CONCLUSIONS Adjusting for these exposures accounted for a substantial but incomplete proportion of racial disparities in incident obesity. Remaining differences may be explained by incomplete capture of the most salient aspects of these exposures or potential variation in the impact of these exposures on obesity by race.

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.

Clinical Prediction Models for Pancreatic Cancer in General and At-Risk Populations: A Systematic Review. Am J Gastroenterol 2023; 118:26-40. [PMID: 36148840 DOI: 10.14309/ajg.0000000000002022] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Accepted: 09/16/2022] [Indexed: 01/12/2023]
Abstract
INTRODUCTION Identifying high-risk individuals using a risk prediction model could be a crucial first stage of screening pathways to improve the early detection of pancreatic cancer. A systematic review was conducted to critically evaluate the published primary literature on the development or validation of clinical risk prediction models for pancreatic cancer risk. METHODS MEDLINE, Embase, and Web of Science were searched for relevant articles from the inception of each database up to November 2021. Study selection and data extraction were conducted by 2 independent reviewers. The Prediction model Risk Of Bias Assessment Tool (PROBAST) was applied to assess risk of bias. RESULTS In total, 33 studies were included, describing 38 risk prediction models. Excluding studies with an overlapping population, this study consist of 15,848,100 participants, of which 58,313 were diagnosed with pancreatic cancer. Eight studies externally validated their model, and 13 performed internal validation. The studies described risk prediction models for pancreatic cancer in the general population (n = 14), patients with diabetes (n = 8), and individuals with gastrointestinal (and other) symptoms (symptoms included abdominal pain, unexplained weight loss, jaundice, and change in bowel habits and indigestion; n = 11). The commonly used clinical risk factors in the model were cigarette smoking (n = 27), age (n = 25), diabetes history (n = 22), chronic pancreatitis (n = 18), and body mass index (n = 14). In the 25 studies that assessed model performance, C-statistics ranged from 0.61 to 0.98. Of the 33 studies included, 6 were rated as being at a low risk of bias based on PROBAST. DISCUSSION Many clinical risk prediction models for pancreatic cancer had been developed for different target populations. Although low risk-of-bias studies were identified, these require external validation and implementation studies to ensure that these will benefit clinical decision making.

Transcriptomic analysis of pancreatic adenocarcinoma specimens obtained from Black and White patients. PLoS One 2023; 18:e0281182.

Abstract
In pancreatic cancer clinical trials, Black patients are under-represented while having higher morbidity and mortality rates as compared to other racial groups. Multiple factors, including socioeconomic and lifestyle factors may contribute to this disparity, but genomic contributions remain unclear. In an exploratory project to identify genes that may contribute to differences in survival between Black (n = 8) and White (n = 20) patients with pancreatic cancer, transcriptomic sequencing of over 24,900 genes was performed in human pancreatic tumor and non-tumor tissue obtained from Black and White patients. Over 4,400 genes were differentially expressed in tumor and non-tumor tissue, irrespective of race. To validate these results, the expression of four genes (AGR2, POSTN, TFF1, and CP) reported to be up-regulated in pancreatic tumor tissue as compared to non-tumor tissue were confirmed using quantitative PCR. Transcriptomic analysis that compared pancreatic tumor tissue from Black and White patients revealed differential expression in 1,200 genes, while a comparison of the non-tumor and tumor gene expression differences within each race revealed over 1,500 tumor-specific differentially expressed genes in pancreatic tumor and non-tumor tissue from Black patients. We identified TSPAN8 as a potential tumor-specific gene significantly overexpressed in pancreatic tumor tissue in Black patients as compared to White patients. Using Ingenuity Pathway Analysis software to compare the race-associated gene expression profiles, over 40 canonical pathways were identified to be potentially impacted by the gene expression differences between the races. Heightened expression of TSPAN8 was associated with poor overall survival, suggesting TSPAN8 as one potential genetic factor contributing to the differential outcomes in Black patients with pancreatic cancer, supporting the potential utility of larger genomic studies to further explore the role of TSPAN8 in pancreatic cancer.

Abstract
Pancreatic cancer (PC) is a highly malignant and aggressive tumor. Despite medical advancement, the silent nature of PC results in only 20% of all cases considered resectable at the time of diagnosis. It is projected to become the second leading cause in 2030. Most pancreatic cancer cases are diagnosed in the advanced stages. Such cases are typically unresectable and are associated with a 5-year survival of less than 10%. Although there is no guideline consensus regarding recommendations for screening for pancreatic cancer, early detection has been associated with better outcomes. In addition to continued utilization of imaging and conventional tumor markers, clinicians should be aware of novel testing modalities that may be effective for early detection of pancreatic cancer in individuals with high-risk factors. The pathogenesis of PC is not well understood; however, various modifiable and non-modifiable factors have been implicated in pancreatic oncogenesis. PC detection in the earlier stages is associated with better outcomes; nevertheless, most oncological societies do not recommend universal screening as it may result in a high false-positive rate. Therefore, targeted screening for high-risk individuals represents a reasonable option. In this review, we aimed to summarize the pathogenesis, genetic risk factors, high-risk population, and screening modalities for PC.

Racial/Ethnic Disparities in the Management of Pediatric Acute Pancreatitis Across Children's Hospitals. J Pediatr Gastroenterol Nutr 2022; 75:650-655. [PMID: 36305883 DOI: 10.1097/mpg.0000000000003597] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/10/2022]
Abstract
OBJECTIVES Racial or ethnic disparities in health care delivery and resource utilization have been reported in a variety of pediatric diseases. In acute pancreatitis (AP), there is an association between Black race and increased inpatient mortality. Data on the association of race and ethnicity and resource use for managing pediatric AP are lacking. The aim of this study is to investigate this potential association in pediatric AP. METHODS Retrospective study of children 0-18 years diagnosed with AP in the Pediatric Health Information System (PHIS) database from 2012 to 2018. Descriptive statistics were used to summarize cohort characteristics. Race/ethnicity classifications included non-Hispanic Black (NHB), non-Hispanic White (NHW, used as reference), Hispanic, and "Other." Associations between patient characteristics and race/ethnicity were determined using χ2 tests. Generalized linear mixed regression model was used to determine the association of race/ethnicity with odds of resource utilization, costs, and length of hospital stay after adjusting for covariates with a random intercept for site. RESULTS Five thousand nine hundred sixty-three patients from 50 hospitals were included. Adjusted analysis showed that NHB children hospitalized with AP were at lower odds of receiving opioids in the first 24 hours [adjusted odds ratio (aOR) = 0.82, 95% confidence interval (CI) = 0.70-0.98] and receiving intravenous fluids during the hospitalization (aOR = 0.64, 95% CI = 0.43-0.96) when compared with NHW children. Additionally, NHB and Hispanic children had a prolonged adjusted mean length of hospital stay and higher hospital costs when compared with NHW children. Although there was no significant association between race/ethnicity and diagnosis of pancreatic necrosis or sepsis, Hispanic and "Other" children were at higher odds of receiving antibiotics during hospitalization for AP (aOR = 1.33, 95% CI = 1.13-1.57 and aOR = 1.37, 95% CI = 1.09-1.73, respectively) than NHW children. CONCLUSIONS Disparities exist in utilization of health care interventions for pediatric AP patients by race/ethnicity. Future studies should investigate why these disparities exist and if these disparities affect outcomes.

Abstract
BACKGROUND Gallstones may result in inflammation, altered bile flow, and changes in metabolic hormone levels, thereby increasing cancer risk. However, previous studies for gallstones and cancers of the liver, biliary tract and pancreas in the U.S. were relatively limited. METHODS We followed 115,036 women from the Nurses' Health Study (1982-2012) and 49,729 men from the Health Professionals Follow-up Study (1986-2012). History of gallstones, including with or without performed cholecystectomy, was reported at baseline and updated through biennial questionnaires. The Cox proportional hazard regression model was used to calculate multivariable hazard ratios (HRs) and 95% confidence intervals (95% CIs). RESULTS During up to 30-year follow-up, we identified 204 incidents of liver cancer, 225 biliary tract cancer and 1147 pancreatic cancer cases. Compared to those without gallstones diagnosis, the multivariable HRs for individuals with gallstones (untreated or with cholecystectomy) were 1.60 for liver cancer (95% CI: 1.14-2.26), 4.79 for biliary tract cancer (95% CI: 3.02-7.58), and 1.13 for pancreatic cancer (95% CI: 0.96-1.32). The multivariable HRs for individuals with cholecystectomy were 1.33 for liver cancer (95% CI: 0.90-1.95) and 1.15 for pancreatic cancer (95% CI: 0.98-1.36). CONCLUSIONS Gallstones were associated with a higher risk of cancers of the liver, biliary tract and possibly pancreas.

Abstract
PURPOSE To investigate the impact of race/ethnicity on surgical outcomes following pancreaticoduodenectomy for pancreatic cancer. METHODS A retrospective review of patients undergoing pancreaticoduodenectomy for adenocarcinoma in the National Surgical Quality Improvement Program (NSQIP) database from 2014 to 2019. Patient and tumor characteristics and 30-day postoperative outcomes were compared. Multivariable logistic and linear regression models were conducted to investigate the relationship between race/ethnicity and surgical outcomes. RESULTS Six thousand five hundred and sixty-two patients were included (84.5% White, 7.9% Black, 3% Hispanic, 4.6% Asian). Larger proportions of Blacks had preoperative American Society of Anesthesiologists class 3 or 4. There were no significant differences in tumor characteristics or operative techniques. A smaller proportion of Asians and Hispanics received neoadjuvant chemotherapy and/or radiation than Blacks and Whites. Relative to White, the Black race was independently associated with postoperative sepsis and reoperation. Both Black and Hispanic race/ethnicity were associated with prolonged intubation and delayed gastric emptying, and minorities races/ethnicities were associated with longer length of hospital stay. Relative to White, Hispanic, and Asian race/ethnicity were independently associated with a lower likelihood of neoadjuvant therapy (NAT) receipt. CONCLUSION In ACS-NSQIP participating hospitals, non-White race/ethnicity was independently associated with adverse outcomes after pancreatic cancer resection. A possible disparity in NAT receipt may exist in Asian and Hispanic patients undergoing surgical resection.

Abstract
Background The gap in treatment and health outcomes after diagnosis of pancreatic cancer is a major public health concern. We aimed to investigate the differences in the health outcomes and treatment of pancreatic cancer patients in healthcare vulnerable and non-vulnerable areas. Methods This retrospective cohort study evaluated data from the Korea National Health Insurance Corporation-National Sample Cohort from 2002 to 2019. The position value for relative comparison index was used to define healthcare vulnerable areas. Cox proportional hazard regression was used to estimate the risk of mortality in pancreatic cancer patients according to healthcare vulnerable areas, and multiple logistic regression was used to estimate the difference in treatment. Results Among 1,975 patients, 279 (14.1%) and 1,696 (85.9%) lived in the healthcare vulnerable and non-vulnerable areas, respectively. Compared with the non-vulnerable area, pancreatic cancer patients in the vulnerable area had a higher risk of death at 3 months (hazard ratio [HR]: 1.33, 95% confidence interval [CI] = 1.06–1.67) and 6 months (HR: 1.23, 95% CI = 1.03–1.48). In addition, patients with pancreatic cancer in the vulnerable area were less likely to receive treatment than patients in the non-vulnerable area (odds ratio [OR]: 0.70, 95% CI = 0.52–0.94). This trend was further emphasized for chemotherapy (OR: 0.68, 95% CI = 0.48–0.95). Conclusion Patients with pancreatic cancer belonging to medically disadvantaged areas receive less treatment and have a higher risk of death. This may be a result of the late diagnosis of pancreatic cancer among these patients.

Abstract
BACKGROUND Gastrointestinal (GI) cancers represent a diverse group of diseases. We assessed differences in geographic and racial disparities in cancer-specific mortality across subtypes, overall and by patient characteristics, in a geographically and racially diverse US population. METHODS Clinical, sociodemographic, and treatment characteristics for patients diagnosed during 2009-2014 with colorectal cancer (CRC), pancreatic cancer, hepatocellular carcinoma (HCC), or gastric cancer in Georgia were obtained from the Surveillance, Epidemiology, and End Results Program database. Patients were classified by geography (rural or urban county) and race and followed for cancer-specific death. Multivariable Cox proportional hazards models were used to calculate stratified hazard ratios (HR) and 95% confidence intervals (CIs) for associations between geography or race and cancer-specific mortality. RESULTS Overall, 77% of the study population resided in urban counties and 33% were non-Hispanic Black (NHB). For all subtypes, NHB patients were more likely to reside in urban counties than non-Hispanic White patients. Residing in a rural county was associated with an overall increased hazard of cancer-specific mortality for HCC (HR = 1.15, 95% CI = 1.02-1.31), pancreatic (HR = 1.11, 95% CI = 1.03-1.19), and gastric cancer (HR = 1.17, 95% CI = 1.03-1.32) but near-null for CRC. Overall racial disparities were observed for CRC (HR = 1.18, 95% CI = 1.11-1.25) and HCC (HR = 1.12, 95% CI = 1.01-1.24). Geographic disparities were most pronounced among HCC patients receiving surgery. Racial disparities were pronounced among CRC patients receiving any treatment. CONCLUSION Geographic disparities were observed for the rarer GI cancer subtypes, and racial disparities were pronounced for CRC. Treatment factors appear to largely drive both disparities.

Abstract
In this paper, a new trimmed regression model under the neutrosophic environment is introduced. The mathematical model of the new regression model along with its neutrosophic form is given. The methods to find the error sum of square and trended values are also given. The trimmed neutrosophic correlation is also introduced in the paper. The proposed trimmed regression is applied to prostate cancer. From the analysis, it is concluded that the proposed model provides the minimum error sum of square as compared to the existing regression model under neutrosophic statistics. It is found that the proposed model is quite effective to forecast prostate cancer patients under an indeterminacy setting.

Trends in the Incidence and Treatment of Early-Onset Pancreatic Cancer. Cancers (Basel) 2022; 14:cancers14020283. [PMID: 35053447 PMCID: PMC8773833 DOI: 10.3390/cancers14020283] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2021] [Revised: 12/24/2021] [Accepted: 12/31/2021] [Indexed: 12/28/2022] Open
Abstract
Simple Summary Pancreatic cancer is being diagnosed more frequently in younger individuals. However, limited insight exists into the magnitude of this increase, which subgroups are most affected, and which treatments are utilized in this population. In our study, we aimed to characterize which, and how, subgroups in the United States were affected by pancreatic cancer from 2000 to 2016. Additionally, we aimed to show which therapies were used to treat young patients with pancreatic cancer. Our findings provide valuable information regarding which subgroups face higher rates of this disease and what therapies have historically been used for treatment. Clinicians, scientists, policymakers, and the general population can use this information to develop programs to educate and identify individuals who are at risk for developing pancreatic cancer at an early age, as well as to study whether younger patients should be treated differently than older patients. Abstract Background: Early-onset pancreatic cancer (EOPC) is relatively uncommon. It is unclear if the incidence of EOPC is evolving and how these patients are treated. Methods: We conducted a retrospective, population-based study using SEER 2004–2016. We evaluated annual age-adjusted incidence rate (AAIR), stage at presentation, and race/ethnicity among 7802 patients plus treatment patterns in 7307 patients (excluding neuroendocrine tumors) younger than 50. Results: The AAIR was higher in males while the rate increased faster in females. The AAIR was highest in Non-Hispanic Black patients and increased for all races/ethnicities over time. The percentage of patients diagnosed with distant-stage disease decreased over time but increased for localized-stage disease. Hispanic patients made up a larger proportion of patients over time compared to other groups. For localized-stage disease, primary surgery alone was the most utilized modality of therapy. For regional-stage disease, chemotherapy with radiation was the most utilized modality from 2004–2010, whereas chemotherapy alone was the most utilized from 2011–2016. For distant-stage disease, chemotherapy alone was the most utilized and used increasingly over time. Patients with EOPC received radiation and chemotherapy at similar rates to, and underwent surgery more frequently, than patients 50–69. Conclusions: The AAIR of EOPC increased over time, faster so in females. Groups who experience a higher burden of pancreatic cancer, particularly African Americans, experienced a higher burden of EOPC. Treatment of localized and regional-stage disease did not follow standard treatment guidelines for pancreatic cancer. Our findings indicate that EOPC patients received more treatment than their older counterparts.

Abstract
Pancreatic cancer is the third leading cause of cancer deaths in the United States. Black patients with pancreatic cancer experience higher incidence and increased mortality. Although racial biologic differences exist, socioeconomic status, insurance type, physician bias, and patient beliefs contribute to the disparities in outcomes observed among patients who are Black, indigenous, and people of color.

Abstract
Paclitaxel is a broad-spectrum anticancer compound, which was derived mainly from a medicinal plant, in particular, from the bark of the yew tree Taxus brevifolia Nutt. It is a representative of a class of diterpene taxanes, which are nowadays used as the most common chemotherapeutic agent against many forms of cancer. It possesses scientifically proven anticancer activity against, e.g., ovarian, lung, and breast cancers. The application of this compound is difficult because of limited solubility, recrystalization upon dilution, and cosolvent-induced toxicity. In these cases, nanotechnology and nanoparticles provide certain advantages such as increased drug half-life, lowered toxicity, and specific and selective delivery over free drugs. Nanodrugs possess the capability to buildup in the tissue which might be linked to enhanced permeability and retention as well as enhanced antitumour influence possessing minimal toxicity in normal tissues. This article presents information about paclitaxel, its chemical structure, formulations, mechanism of action, and toxicity. Attention is drawn on nanotechnology, the usefulness of nanoparticles containing paclitaxel, its opportunities, and also future perspective. This review article is aimed at summarizing the current state of continuous pharmaceutical development and employment of nanotechnology in the enhancement of the pharmacokinetic and pharmacodynamic features of paclitaxel as a chemotherapeutic agent.

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
Stromal cells play crucial roles in tumor development and are increasingly attractive targets for therapy. There are considerable racial disparities in the incidence and progression of many tumors, reflecting both environmental exposure and genetic differences existing between races. Tumorigenesis and tumor progression are linked to both the propensity to suffer an initiating event and the host response to such an event once it occurs, contributing to incidence and outcomes. In this review, we focused on racial disparities in the tumor microenvironment (TME) of different cancers as potential modulators of growth, metastasis, and response to treatment. Several studies suggest that the TME in AA has a distinct tumor biology and may facilitate both early onset and aggressive tumor growth while inhibiting anti-tumorigenic properties. The TME of AA patients often exhibits an immunosuppressive microenvironment with a substantial enrichment of immune inflammatory pathways and genes. As a result, AA patients can potentially benefit more from treatment strategies that modulate the immune system. Focusing on TME components for diagnostic and therapeutic purposes to address racial disparities is a promising area of investigation. Future basic and clinical research studies on personalized cancer diagnosis and treatment should acknowledge the significance of TME in racial disparities.

Abstract
BACKGROUND Gallstone disease (GSD) is associated with a higher risk of gastrointestinal (GI) cancer. However, it is unclear whether the associations are causal. METHODS The prospective China Kadoorie Biobank (CKB) recorded 17,598 cases of GI cancer among 510,137 participants without cancer at baseline during 10 years of follow-up. Cox regression was used to estimate hazard ratios (HRs) for specific cancer by GSD status and duration. Mendelian randomisation was conducted to assess the genetic associations of GSD with specific cancer. RESULTS Overall 6% of participants had symptomatic GSD at baseline. Compared with those without GSD, individuals with symptomatic GSD had adjusted HRs of 1.13 (1.01-1.29) for colorectal, 2.01 (1.78-2.26) for liver, 3.70 (2.88-4.87) for gallbladder, 2.31 (1.78-3.07) for biliary tract, and 1.38 (1.18-1.74) for pancreatic cancer. Compared with participants without GSD, the risks of colorectal, liver, gallbladder, biliary tract, and pancreatic cancer were highest during 0 to <5 years following disease diagnosis. There was evidence of genetic associations of GSD with these cancers, with odds ratios per 1-SD genetic score of 1.08 (1.05-1.11) for colorectal, 1.22 (1.19-1.25) for liver, 1.56 (1.49-1.64) for gallbladder, 1.39 (1.31-1.46) for biliary tract, and 1.16 (1.10-1.22) for pancreatic cancer. When meta-analysing the genetic estimates in CKB and UK Biobank, there was evidence of causal associations of GSD with colon cancer, gallbladder and biliary tract cancer (GBTC), and total GI cancer (RR per 1-SD: 1.05 [0.99-1.11], 2.00 [1.91-2.09], and 1.09 [1.05-1.13]). CONCLUSIONS GSD was associated with higher risks of several GI cancers, warranting future studies on the underlying mechanisms.

Municipality and Adjusted Gross Income Influence Outcome of Patients Diagnosed with Pancreatic Cancer in a Newly Developed Cancer Center in Mercer County New Jersey, USA, a Single Center Study. Cancers (Basel) 2021; 13:cancers13071498. [PMID: 33805136 PMCID: PMC8037458 DOI: 10.3390/cancers13071498] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Accepted: 03/22/2021] [Indexed: 11/17/2022] Open
Abstract
Socioeconomic status (SES) correlates directly to ZIP code. Mercer County is not atypical as a collection of a dozen municipalities with a suburban/metropolitan population of 370,430 in the immediate vicinity of a major medical center. The purpose of this study for Mercer County, New Jersey, USA is to determine whether a patient's ZIP code is related to the outlook of pancreatic cancer defined as staging at diagnosis, prevalence, overall survival, type of insurance, and recurrence. Our hypothesis was that specific variables such as socio-economic status or race could be linked to the outcome of patients with pancreatic cancer. We interrogated a convenience sample from our cancer center registry and obtained 479 subjects diagnosed with pancreatic cancer in 1998-2018. We selected 339 subjects by ZIP code, representing the plurality of the cases in our catchment area. The outcome variable was overall survival; predictor variables were socio-economic status (SES), recurrence, insurance, type of treatment, gender, cancer stage, age, and race. We converted ZIP code to municipality and culled data using adjusted gross income (AGI, FY 2017). Comparative statistical analysis was performed using chi-square tests for nominal and ordinal variables, and a two-way ANOVA test was used for continuous variables; the p-value was set at 0.05. Our analysis confirmed that overall survival was significantly higher for Whites and for individuals who live in a municipality with a high SES. Tumor stage at the time of diagnosis was not different among race and SES; however, statistically significant differences for race or SES existed in the type of treatment received, with disparities found in those who received radiation therapy and surgery but not chemotherapy. The data may point to a lack of access to specific care modalities that subsequently may lead to lower survival in an underserved population. Access to care, optimal nutritional status, overall fitness, and co-morbidities could play a major role and confound the results. Our study suggests that low SES has a negative impact on overall pancreatic cancer survival. Surgery for pancreatic cancer should be appropriately decentralized to those community cancer centers that possess the expertise and the infrastructure to carry out specialized treatments regardless of race, ethnicity, SES, and insurance.

Abstract
PURPOSE Pancreatic adenocarcinoma remains a malignancy with poor prognosis. Black patients experience poorer overall survival compared with other races. Recent studies have elucidated certain prognostic factors at the time of diagnosis of pancreatic cancer which have largely not been studied for differences between racial groups. We present a study examining differences in blood levels between Black and non-Black patients and their effects on overall survival. METHODS This is a retrospective cohort study. One hundred sixty-three patients were confirmed to carry a tissue diagnosis of pancreatic adenocarcinoma and included in analysis; 27 of the patients were self-identified as "Black"; 136 were analyzed together as "Non-Black" with the majority identifying as "White". Various blood markers were drawn at the time of diagnosis. Kaplan-Meier and multivariable Cox regression models were used to examine differences in these factors between Black and non-Black patients, as well as their effect on overall survival. RESULTS Black patients were younger at diagnosis (p = 0.001) and were more likely to experience significant weight loss leading up to diagnosis (p = 0.009); Black patients also had a lower neutrophil-to-lymphocyte ratio (NLR) (p = 0.001) and higher lymphocyte-to-monocyte ratio (LMR) (p = 0.001) at diagnosis. In multivariable analysis, an NLR > 3.5 had a significantly negative impact on overall survival (p = 0.002), as did the presence of metastatic disease (p < 0.001). CONCLUSION Black patients demonstrated a "favorable" white blood cell profile (higher LMR, lower NLR) compared with non-Black patients. This may suggest that the immune response in pancreatic adenocarcinoma is not what is driving disparately poor outcomes in Black patients. Further study is warranted to ascertain the role of immune response in pancreatic adenocarcinoma, the prognostic use of these measurements at diagnosis, and possible other factors, such as genetics, which may better explain poorer outcomes in Black patients.

Abstract
Background: Well-annotated, high-quality biorepositories provide a valuable platform to support translational research. However, most biorepositories have poor representation of minority groups, limiting the ability to address health disparities. Methods: We describe the establishment of the Florida Pancreas Collaborative (FPC), the first state-wide prospective cohort study and biorepository designed to address the higher burden of pancreatic cancer (PaCa) in African Americans (AA) compared to Non-Hispanic Whites (NHW) and Hispanic/Latinx (H/L). We provide an overview of stakeholders; study eligibility and design; recruitment strategies; standard operating procedures to collect, process, store, and transfer biospecimens, medical images, and data; our cloud-based data management platform; and progress regarding recruitment and biobanking. Results: The FPC consists of multidisciplinary teams from fifteen Florida medical institutions. From March 2019 through August 2020, 350 patients were assessed for eligibility, 323 met inclusion/exclusion criteria, and 305 (94%) enrolled, including 228 NHW, 30 AA, and 47 H/L, with 94%, 100%, and 94% participation rates, respectively. A high percentage of participants have donated blood (87%), pancreatic tumor tissue (41%), computed tomography scans (76%), and questionnaires (62%). Conclusions: This biorepository addresses a critical gap in PaCa research and has potential to advance translational studies intended to minimize disparities and reduce PaCa-related morbidity and mortality.

Abstract
BACKGROUND AND OBJECTIVES Black patients with pancreatic ductal adenocarcinoma (PDAC) are less likely to receive multimodality treatment and have worse survival compared to White patients. However, little is known regarding racial differences in postoperative outcomes. The primary aim of this study was to determine if 30-day complication rates following pancreaticoduodenectomy (PD) differ by race. METHODS A retrospective cohort study of patients who underwent PD for PDAC from 2014 to 2016 within the ACS-NSQIP pancreatectomy-specific data set was performed. Primary outcomes were 30-day pancreas-specific and overall major complications. RESULTS A total of 6936 patients were identified, including 91.4% (N = 6337) White and 8.6% (N = 599) Black. Pathologic stage and rates of neoadjuvant therapy were similar among Whites and Blacks. Rates of pancreas-specific (23.9% vs. 23.1%, p = .88) and major postoperative complications (39.2% vs. 39.9%, p = .55) were similar between Whites and Blacks. By multivariable regression analysis, there was no association between race and odds of pancreas-specific complications (odds ratio [OR] 1.10, 95% confidence interval [CI] 0.89-1.37) or overall major complications (OR 1.13, 95% CI 0.95-1.36). CONCLUSIONS Among patients undergoing PD for PDAC, Black race is not associated with increased pancreas-specific or overall 30-day postoperative complications. Short-term postoperative outcomes do not appear to explain the increase in pancreatic cancer mortality among Black patients.

Abstract
Background People with diabetes are at an increased risk of developing pancreatic cancer. However, it is unclear whether diabetes-related complications are associated with risk of pancreatic cancer. Methods A nested matched case-control analysis was conducted among the fee-for-service Medicare participants of the prospective Multiethnic Cohort (n = ∼123 000). Between 2001 and 2014, 433 incident cases of pancreatic ductal adenocarcinoma were matched to 1728 controls by birth year, sex, race and ethnicity, and age at cohort entry. Participants were linked to data from the California and Hawaii cancer registries and Medicare claims. We used the diabetes complications severity index (DCSI) for the presence of 7 complications within 2 years prior to the diagnosis date of the index case. Multivariable conditional logistic regression was used to examine the association of DCSI with pancreatic cancer incidence. Results Diabetes was present among 45.4% of cases and 34.1% of controls. Cases had higher DCSI score compared with controls (score ≥4: 32.8% in cases; 21.2% in controls). The most prevalent diabetes-related complications for cases were cardiovascular disease (61.2%), nephropathy (31.2%), and cerebrovascular disease (21.7%). Individuals with diabetes (odds ratio [OR] = 1.48, 95% confidence interval [CI] = 1.14 to 1.91), nephropathy (OR = 1.75, 95% CI = 1.32 to 2.33), cardiovascular disease (OR = 1.88, 95% CI = 1.45 to 2.44), and metabolic complications (OR = 6.61, 95% CI = 2.49 to 17.50) were at increased risk of pancreatic cancer. For every 1-unit increase in DCSI score, participants had 18% greater risk of pancreatic cancer (OR = 1.18, 95% CI = 1.11 to 1.25). Conclusions Participants with diabetes-related complications have an elevated risk of pancreatic cancer. Identifying diabetes-related complications may help identify high-risk groups who can be studied for development of early markers for this fatal cancer.

Abstract
OBJECTIVES The aim of this study was to investigate racial and socioeconomic disparities for patients with pancreatic cancer across different facility types. METHODS The National Cancer Database was queried for pancreatic cancer cases from 2004 to 2015. Along with propensity score matching analysis, multivariate logistic and Cox model were used to assess effects of facility type, race, elements of socioeconomics on receipt of treatment, time to treatment, and overall survival, separately. RESULTS Among 223,465 patients, 44.6%, 42.1%, and 13.3% were treated at academic, community, and integrated facilities, respectively. Private insurance was associated with more treatment (odds ratio, 1.41; P < 0.001) and better survival [hazards ratio (HR), 0.84; P < 0.001]. Higher education was associated with earlier treatment (HR, 1.09; P < 0.001). African Americans had less treatment (odds ratio, 0.97; P = 0.04) and delayed treatment (HR, 0.89; P < 0.001) despite later stage at diagnosis. After adjusting for socioeconomic status, African Americans had similar survival (HR, 0.99; P = 0.11) overall and improved survival (HR, 0.95; P = 0.016) at integrated facilities. CONCLUSIONS Higher socioeconomic status was associated with better treatment and survival. After adjusting for socioeconomic disparities, race did not affect survival. Less racial disparity was observed at integrated facilities.

Abstract
Previous research has revealed a positive relationship between GSD, cholecystectomy and primary liver cancer (PLC). However, previous studies had several limitations including the retrospective design, narrow assessment of potential confounders and lack of competing risk models in time-to-event analyses. We conducted a large prospective cohort study to explore the relationship between GSD, cholecystectomy and PLC. A total of 95,021 participants who had not been diagnosed with PLC previously were enrolled from the Kailuan Cohort study. Demographic characteristics and biochemical parameters were recorded at baseline for all participants. We used Cox regression models and competing risk regression models to evaluate the association of GSD and cholecystectomy with the risk PLC. A total of 306 incidental PLC cases were identified during a median follow-up of 9.05 (8.75-9.22) years per participant. Compared with the normal group, the multivariable HRs (95%CI) for the association of GSD and cholecystectomy with PLC were 1.77 (1.05-2.94), 5.25 (1.95-14.17). In the CS model, the multivariable HRs (95%CI) was 1.76 (1.05-2.94) for the association of GSD and cholecystectomy with PLC and 5.25 (1.95-14.17) for GSD and cholecystectomy. Similar results were also obtained in the SD model with corresponding multivariate HRs (95%CI) of 1.75 (1.01-3.00), 5.22 (1.90-14.07) in the GSD group and cholecystectomy group, respectively. GSD and cholecystectomy were associated with an elevated risk of PLC.Registration number: ChiCTR-TNRC-11001489.

Comprehensive Analysis of Expression, Clinicopathological Association and Potential Prognostic Significance of RABs in Pancreatic Cancer. Int J Mol Sci 2020; 21:ijms21155580. [PMID: 32759795 PMCID: PMC7432855 DOI: 10.3390/ijms21155580] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Revised: 07/27/2020] [Accepted: 07/30/2020] [Indexed: 12/24/2022] Open
Abstract
RAB proteins (RABs) represent the largest subfamily of Ras-like small GTPases that regulate a wide variety of endosomal membrane transport pathways. Their aberrant expression has been demonstrated in various malignancies and implicated in pathogenesis. Using The Cancer Genome Atlas (TCGA) database, we analyzed the differential expression and clinicopathological association of RAB genes in pancreatic ductal adenocarcinoma (PDAC). Of the 62 RAB genes analyzed, five (RAB3A, RAB26, RAB25, RAB21, and RAB22A) exhibited statistically significant upregulation, while five (RAB6B, RAB8B, RABL2A, RABL2B, and RAB32) were downregulated in PDAC as compared to the normal pancreas. Racially disparate expression was also reported for RAB3A, RAB25, and RAB26. However, no clear trend of altered expression was observed with increasing stage and grade, age, and gender of the patients. PDAC from occasional drinkers had significantly higher expression of RAB21 compared to daily or weekly drinkers, whereas RAB25 expression was significantly higher in social drinkers, compared to occasional ones. The expression of RABL2A was significantly reduced in PDAC from diabetic patients, whereas RAB26 was significantly lower in pancreatitis patients. More importantly, a significant association of high expression of RAB21, RAB22A, and RAB25, and low expression of RAB6B, RABL2A, and RABL2B was observed with poorer survival of PC patients. Together, our study suggests potential diagnostic and prognostic significance of RABs in PDAC, warranting further investigations to define their functional and mechanistic significance.

Abstract
Pancreatic adenocarcinoma (PDAC) is associated with poor clinical outcomes and incomplete responses to conventional therapy. Therefore, there is an unmet clinical need to better understand the predisposing factors for pancreatic cancer in hopes of providing early screening to high-risk patients. While select risk factors such as age, race, and family history, or predisposing syndromes are unavoidable, there are several new and established risk factors that allow for intervention, namely by counseling patients to make the appropriate lifestyle modifications. Here, we discuss the best-studied risk factors for PDAC such as tobacco use and chronic pancreatitis, as well as newly emerging risk factors including select nutritional deficits, bacterial infections, and psychosocial factors. As several of these risk factors appear to be additive or synergistic, by understanding their relationships and offering coordinated, multidisciplinary care to high-risk patients, it may be possible to reduce pancreatic cancer incidence and improve clinical outcomes through early detection.

Abstract
Higher body mass index (BMI; weight (kg)/height (m)2) is associated with increased risk of pancreatic cancer in epidemiologic studies. However, BMI has usually been assessed at older ages, potentially underestimating the full impact of excess weight. We examined the association between BMI and pancreatic cancer mortality among 963,317 adults who were aged 30-89 years at their enrollment in Cancer Prevention Study II in 1982. During follow-up through 2014, a total of 8,354 participants died of pancreatic cancer. Hazard ratios per 5 BMI units, calculated using proportional hazards regression, declined steadily with age at BMI assessment, from 1.25 (95% confidence interval: 1.18, 1.33) in persons aged 30-49 years at enrollment to 1.13 (95% confidence interval: 1.02, 1.26) in those aged 70-89 years at enrollment (P for trend = 0.005). On the basis of a hazard ratio of 1.25 per 5 BMI units at age 45 years, we estimated that 28% of US pancreatic cancer deaths among persons born in 1970-1974 will be attributable to BMI ≥25.0-nearly twice the equivalent proportion of those born in the 1930s, a birth cohort with much lower BMI in middle age. These results suggest that BMI before age 50 years is more strongly associated with pancreatic cancer risk than BMI at older ages, and they underscore the importance of avoiding excess weight gain before middle age for preventing this highly fatal cancer.

Abstract
Importance Pancreatic ductal adenocarcinoma (PDAC) has a higher incidence and worse outcomes among black patients than white patients, potentially owing to a combination of socioeconomic, biological, and treatment differences. The role that these differences play remains unknown. Objectives To determine the level of survival disparity between black and white patients in a modern PDAC cohort and whether treatment inequity is associated with such a disparity. Design, Setting, and Participants This cohort study used data on 278 936 patients with PDAC with database-defined race from the National Cancer Database from January 1, 2004, to December 31, 2015. The median follow-up for censored patients was 24 months. The National Cancer Database, comprising academic and community facilities, includes about 70% of new cancer diagnoses in the United States. Race-stratified receipt of therapy was the primary variable of interest. Multivariable analyses included additional demographic and clinical parameters. Data analysis was initially completed on November 30, 2018, and revised data analysis was completed on June 27, 2019. Main Outcomes and Measures Overall survival was the primary outcome, analyzed with Kaplan-Meier and multivariable Cox proportional hazards regression modeling. Results The cohort included 278 936 patients (137 121 women and 141 815 men; mean [SD] age, 68.72 [11.57] years); after excluding patients from other racial categories, 243 820 of the 278 936 patients (87.4%) were white and 35 116 of the 278 936 patients (12.6%) were black. Unadjusted median overall survival was longer for white patients than for black patients (6.6 vs 6.0 months; P < .001). Black patients presented at younger ages than white patients (15 819 of 35 116 [45.0%] vs 83 846 of 243 820 [34.4%] younger than 65 years; P < .001) and with more advanced disease (20 853 of 31 600 [66.0%] vs 135 317 of 220 224 [61.4%] with stage III or IV disease; P < .001). Black patients received fewer surgical procedures than white patients for potentially resectable stage II disease (4226 of 8097 [52.2%] vs 39 214 of 65 124 [60.2%]; P < .001) and slightly less chemotherapy for advanced disease (2756 of 4067 [67.8%] vs 17 296 of 25 227 [68.6%] for stage III disease [P = .001]; 8208 of 16 104 [51.0%] vs 58 603 of 105 616 [55.5%] for stage IV disease [P < .001]). Decreased survival for black patients persisted in multivariable modeling controlled for sociodemographic parameters (hazard ratio, 1.04 [95% CI, 1.02-1.05]). Conversely, modeling that controlled specifically for clinical parameters such as disease stage and treatment revealed a modest survival advantage (hazard ratio, 0.94 [95% CI, 0.93-0.96]) among black patients. Resection was the factor most strongly associated with overall survival (hazard ratio, 0.39 [95% CI, 0.38-0.39]). Conclusions and Relevance Black patients with PDAC present at younger ages and with more advanced disease than white patients, suggesting that differences in tumor biology may exist. Black patients receive less treatment stage for stage and fewer surgical procedures for resectable cancers than white patients; these findings may be only partly associated with socioeconomic differences. When disease stage and treatment were controlled for, black patients had no decrease in survival.

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
Current evidence on cigarette smoking associated with pancreatic cancer mortality is limited. We searched MEDLINE, Web of Science, and Embase databases to identify relevant studies published through January 31, 2018. A random-effects model was used to estimate summary hazard ratios (HRs) and 95% confidence intervals (CIs). A total of 20 studies were retrieved, involving 2,517,623 participants. Of these, more than 15,341 patients with pancreatic cancer died. Compared with never smokers, current (summary HR, 1.56; 95% CI, 1.34-1.83) and former (summary HR, 1.15; 95% CI, 1.06-1.26) smokers had elevated risk of total mortality in patients diagnosed with pancreatic cancer. This effect of cigarette smoking is observed both in the Western regions and the Asia-Pacific regions. This effect of smoking is independent of alcohol use, body mass index, and history of diabetes but is modified by tumor stage and study settings. Dose-response associations between smoking and pancreatic cancer mortality were revealed for smoking intensity, cumulative amount of cigarettes smoked, and duration of smoking. Cigarette smoking was associated with an increase in total mortality for patients with pancreatic cancer. Future studies should further clarify the role of smoking as an effect modifier in treatment trials of pancreatic cancer.

Abstract
OBJECTIVE To perform an epidemiologic profile of pancreatic cancer (PC) in Puerto Rico (PR) with data gathered from 2001 to 2015. METHODS Using data from the PR Central Cancer Registry we estimated incidence and mortality rates and trends of PC in PR, and performed survival analyses. We also compared the age-standardized incidence and mortality rates of PC in people in PR with those of Hispanics, non-Hispanic whites, and non Hispanic blacks in the United States (US). RESULTS From 2011 to 2015, 7.8 per 100,000 persons were diagnosed with PC in PR; higher rates were observed in men than in women (9.2 vs. 6.7 per 100,000, respectively) and in persons 65 years old and older (42.7 per 100,000 persons). For the same period, 6.7 per 100,000 persons died from PC; men and persons 65 years and older had higher mortality rates. Incidence and mortality trends of PC in PR increased from 2001-2015 (annual percent change [APC] = 3.8% and 1.9%, respectively (p<0.05). Lower risk of being diagnosed with and dying from PC was seen in PR than in members of several racial/ethnic groups in the US. The median survival time for PC cases diagnosed in PR during the period of 2008 to 2012 was 5.3 months. CONCLUSION We observed increasing mortality rates and low survival in PC patients in PR. Research on access and response to treatment is needed to elucidate the reasons for the observed results and have a positive impact on PC burden and survival.

Abstract
Pancreatic cancer (PC) is characterized by racial/ethnic disparities and the debilitating muscle-wasting condition, cancer cachexia. Florida ranks second in the number of PC deaths and has a large and understudied minority population. We examined the primary hypothesis that PC incidence and mortality rates may be highest among Black Floridians and the secondary hypothesis that biological correlates of cancer cachexia may underlie disparities. PC incidence and mortality rates were estimated by race/ethnicity, gender, and county using publicly available state-wide cancer registry data that included approximately 2700 Black, 25 200 Non-Hispanic White (NHW), and 3300 Hispanic/Latino (H/L) Floridians diagnosed between 2004 and 2014. Blacks within Florida experienced a significantly (P < 0.05) higher incidence (12.5/100 000) and mortality (10.97/100 000) compared to NHW (incidence = 11.2/100 000; mortality = 10.3/100 000) and H/L (incidence = 9.6/100 000; mortality = 8.7/100 000), especially in rural counties. To investigate radiologic and blood-based correlates of cachexia, we leveraged data from a subset of patients evaluated at two geographically distinct Florida Cancer Centers. In Blacks compared to NHW matched on stage, markers of PC-induced cachexia were more frequent and included greater decreases in core musculature compared to corresponding healthy control patients (25.0% vs 10.1% lower), greater decreases in psoas musculature over time (10.5% vs 4.8% loss), lower baseline serum albumin levels (3.8 vs 4.0 gm/dL), and higher platelet counts (332.8 vs 268.7 k/UL). Together, these findings suggest for the first time that PC and cachexia may affect Blacks disproportionately. Given its nearly universal contribution to illness and PC-related deaths, the early diagnosis and treatment of cachexia may represent an avenue to improve health equity, quality of life, and survival.

Abstract
While disparity in pancreatic cancer incidence between blacks and whites has been observed, few studies have examined disparity in other ethnic minorities. We evaluated variations in pancreatic cancer incidence and assessed the extent to which known risk factors account for differences in pancreatic cancer risk among African Americans, Native Hawaiians, Japanese Americans, Latino Americans, and European Americans in the Multiethnic Cohort Study. Risk factor data were obtained from the baseline questionnaire. Cox regression was used to estimate the relative risks (RRs) and 95% confidence intervals (CIs) for pancreatic cancer associated with risk factors and ethnicity. During an average 16.9-year follow-up, 1,532 incident pancreatic cancer cases were identified among 184,559 at-risk participants. Family history of pancreatic cancer (RR 1.97, 95% CI 1.50-2.58), diabetes (RR 1.32, 95% CI 1.14-1.54), body mass index ≥30 kg/m2 (RR 1.25, 95% CI 1.08-1.46), current smoking (<20 pack-years RR 1.43, 95% CI 1.19-1.73; ≥20 pack-years RR 1.76, 95% CI 1.46-2.12), and red meat intake (RR 1.17, 95% CI 1.00-1.36) were associated with pancreatic cancer. After adjustment for these risk factors, Native Hawaiians (RR 1.60, 95% CI 1.30-1.98), Japanese Americans (RR 1.33, 95% CI 1.15-1.54), and African Americans (RR 1.20, 95% CI 1.01-1.42), but not Latino Americans (RR 0.90, 95% CI 0.76-1.07), had a higher risk of pancreatic cancer compared to European Americans. Interethnic differences in pancreatic cancer risk are not fully explained by differences in the distribution of known risk factors. The greater risks in Native Hawaiians and Japanese Americans are new findings and elucidating the causes of these high rates may improve our understanding and prevention of pancreatic cancer.

Gerlovin H, Michaud DS, Cozier YC, Palmer JR. Oral Health in Relation to Pancreatic Cancer Risk in African American Women. Cancer Epidemiol Biomarkers Prev 2019; 28:675-679. [PMID: 30923045 DOI: 10.1158/1055-9965.epi-18-1053] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Revised: 11/19/2018] [Accepted: 01/14/2019] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Incidence of pancreatic cancer is higher in African Americans than in U.S. whites. We hypothesized that poor oral health, disproportionately common in African Americans and associated with increased risk of pancreatic cancer in several studies of predominantly white populations, may play a role in this disparity. METHODS We examined the relation of self-reported measures of oral health (periodontal disease and adult tooth loss) in relation to pancreatic cancer incidence in the prospective Black Women's Health Study (BWHS). Cox proportional hazard analyses were used to calculate HRs of pancreatic cancer for women with periodontal disease, tooth loss, or both, relative to women who reported neither. Multivariable models adjusted for age, cigarette smoking, body mass index (BMI), type 2 diabetes, and alcohol consumption. RESULTS Participants aged 33 to 81 were followed for an average of 9.85 years from 2007 through 2016, with occurrence of 78 incidence cases of pancreatic cancer. Multivariable HRs for pancreatic cancer incidence were 1.77 [95% confidence interval (CI) 0.57-5.49] for periodontal disease with no tooth loss, 2.05 (95% CI, 1.08-3.88) for tooth loss without report of periodontal disease, and 1.58 (95% CI, 0.70-3.57) for both tooth loss and periodontal disease. The HR for loss of at least five teeth, regardless of whether periodontal disease was reported, was 2.20 (95% CI, 1.11-4.33). CONCLUSIONS The poor oral health experienced by many African Americans may contribute to their higher incidence of pancreatic cancer. IMPACT Future research will assess associations between the oral microbiome and pancreatic cancer risk in this population.

Application of Neutrosophic Logic to Evaluate Correlation between Prostate Cancer Mortality and Dietary Fat Assumption. Symmetry (Basel) 2019.

Abstract
This paper presents an epidemiological study on the dietary fat that causes prostate cancer in an uncertainty environment. To study this relationship under the indeterminate environment, data from 30 countries are selected for the prostate cancer death rate and dietary fat level in the food. The neutrosophic correlation and regression line are fitted on the data. We note from the neutrosophic analysis that the prostate cancer death rate increases as the dietary fat level in the people increases. The neutrosophic regression coefficient also confirms this claim. From this study, we conclude that neutrosophic regression is a more effective model under uncertainty than the regression model under classical statistics. We also found a statistical correlation between dietary fat and prostate cancer risk.

Abstract
Pancreatic cancer is the seventh leading cause of cancer-related deaths worldwide. However, its toll is higher in more developed countries. Reasons for vast differences in mortality rates of pancreatic cancer are not completely clear yet, but it may be due to lack of appropriate diagnosis, treatment and cataloging of cancer cases. Because patients seldom exhibit symptoms until an advanced stage of the disease, pancreatic cancer remains one of the most lethal malignant neoplasms that caused 432,242 new deaths in 2018 (GLOBOCAN 2018 estimates). Globally, 458,918 new cases of pancreatic cancer have been reported in 2018, and 355,317 new cases are estimated to occur until 2040. Despite advancements in the detection and management of pancreatic cancer, the 5-year survival rate still stands at 9% only. To date, the causes of pancreatic carcinoma are still insufficiently known, although certain risk factors have been identified, such as tobacco smoking, diabetes mellitus, obesity, dietary factors, alcohol abuse, age, ethnicity, family history and genetic factors, Helicobacter pylori infection, non-O blood group and chronic pancreatitis. In general population, screening of large groups is not considered useful to detect the disease at its early stage, although newer techniques and the screening of tightly targeted groups (especially of those with family history), are being evaluated. Primary prevention is considered of utmost importance. Up-to-date statistics on pancreatic cancer occurrence and outcome along with a better understanding of the etiology and identifying the causative risk factors are essential for the primary prevention of this disease.

Closing the Disparity in Pancreatic Cancer Outcomes: A Closer Look at Nonmodifiable Factors and Their Potential Use in Treatment. Pancreas 2019; 48:242-249. [PMID: 30629027 DOI: 10.1097/mpa.0000000000001238] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/07/2023]
Abstract
OBJECTIVES African Americans (AAs) have disproportionately higher incidence and lower survival rates from pancreatic cancer compared with whites. Historically, this disparity has been attributed to modifiable risk factors. Recent studies suggest that nonmodifiable aspects may also play an important role. We review these new contributions as potential targets for closing the disparity. METHODS A PubMed search was conducted to review studies of nonmodifiable elements contributing to pancreatic cancer disparities in AAs. RESULTS Several nonmodifiable risks are associated with the racial disparity in pancreatic cancer. SSTR5 P335L, Kaiso, and KDM4/JMJD2A demonstrate differential racial expression, increasing their potential as therapeutic targets. Many social determinants of health and their associations with diabetes, obesity, and the microbiome are partially modifiable risk factors that significantly contribute to outcomes in minorities. Barriers to progress include the low minority inclusion in research studies. CONCLUSIONS Genomics, epigenetics, the microbiome, and social determinants of health are components that contribute to the pancreatic cancer disparity in AAs. These factors can be researched, targeted, and modified to improve mortality rates. Closing the disparity in pancreatic cancer will require an integrated approach of personalized medicine, increased minority recruitment to studies, and advanced health care/education access.

Abstract
OBJECTIVES Adenocarcinoma of the pancreas represents the third leading cause of cancer-related death in the United States. Drug combinations, FOLFIRINOX (5-FU, leucovorin, irinotecan, and oxaliplatin) and gemcitabine/nab-paclitaxel, showed a clinically meaningful benefit when compared with single-agent gemcitabine in phase III trials. The goal of this study was to investigate whether there was an increase in overall survival (OS) for patients treated for metastatic pancreatic cancer after the introduction of the above regimens. MATERIALS AND METHODS Patients were grouped into 2 treatment eras that were before and after the introduction of these newer chemotherapeutic regimens; 2006-2010 and 2011-2015, respectively. Baseline demographics and disease-related variables were collected from metastatic pancreatic cancer treated at the Barbara Ann Karmanos Cancer Institute in Detroit, MI. RESULTS When stratified by treatment era, the later era had an improvement in survival (hazard ratio for death of 0.61; P=0.005). Median OS was 8.97 and 9.95 months for the earlier (n=59) versus latter era (n=99), respectively. There was an increase from 28.3% to 38.9% at 12 months between the earlier and later era, an improvement of 37.4%. African Americans had a worse outcome with a hazard ratio of 1.63 (P=0.02) for death. When comparing the eras, Caucasians had a longer median OS in each era in addition to having a greater improvement in median OS between eras. CONCLUSIONS There was a modest improvement in median OS between 2006-2010 and 2011-2015 with the introduction of newer chemotherapeutic regimens. However, there has been no significant improvement in outcomes for African Americans or in short-term survival.

Abstract
Ethnic health disparity is a well-acknowledged issue in many disease settings, but not diseases of the exocrine pancreas. A systematic review and meta-analysis was conducted to explore the race- and ethnicity-specific burden of diseases of the exocrine pancreas. Studies that compared health-related endpoints between two or more ethnicities were eligible for inclusion. Proportion meta-analyses were conducted to compare burden between groups. A total of 42 studies (24 on pancreatic cancer, 17 on pancreatitis, and one on pancreatic cyst) were included in the systematic review, of which 19 studies were suitable for meta-analyses. The incidence of pancreatic cancer was 1.4-fold higher among African-Americans, while the incidence of acute pancreatitis was 4.8-fold higher among an indigenous population (New Zealand Māori) compared with Caucasians. The prevalence of post-pancreatitis diabetes mellitus was up to 3.0-fold higher among certain ethnicities, including Asians, Pacific Islanders, and indigenous populations compared with Caucasians. The burden of diseases of the exocrine pancreas differs between ethnicities, with African-Americans and certain indigenous populations being at the greatest risk of developing these diseases. Development of race- and ethnicity-specific screening as well as protocols for lifestyle modifications may need to be considered with a view to reducing the disparities in burden of diseases of the exocrine pancreas.

Abstract
BACKGROUND The aim of this study was to evaluate health disparities in the outcomes of patients with resectable pancreatic adenocarcinoma. METHODS We retrospectively analyzed 280,935 patients from the National Cancer Data Base (NCDB), from 1998 to 2012 to compare the differences in patient characteristics, refusal of offered surgical treatment and overall survival after pancreatic adenocarcinoma resection between white vs. black patients. RESULTS Black patients did not undergo and refused offered surgical treatment more frequently. Race and insurance were the most important factors independently associated with not receiving the offered resection. Having private insurance, Hispanic ethnic background, geographic location, higher income, residing in urban/metropolitan area and systemic treatment were independently associated with improved survival. Race was associated with overall worse survival in an unadjusted model but not in multivariable analysis. The association between race and survival was removed when adjusting for facility location, income, education, tumor size, tumor stage or systemic treatment. CONCLUSION Disparities exist at various levels in resectable pancreatic cancers. These findings help developing targeted interventions and quality improvement initiatives.
