Abstract
INTRODUCTION Our analysis was designed to characterize the demographics and disparities between the diagnosis of pancreas cancer during emergency presentation (EP) and the outpatient setting (OP) and to see the impact of our institutions pancreatic multidisciplinary clinic (PMDC) on these disparities. METHODS Institutional review board-approved retrospective review of our institutional cancer registry and PMDC databases identified patients diagnosed/treated for pancreatic ductal adenocarcinoma between 2014 and 2022. Chi-square tests were used for categorical variables, and one-way ANOVA with a Bonferroni correction was used for continuous variables. Statistical significance was set at p < 0.05. RESULTS A total of 286 patients met inclusion criteria. Eighty-nine patients (31.1%) were underrepresented minorities (URM). Fifty-seven (64.0%) URMs presented during an EP versus 100 (50.8%) non-URMs (p = 0.037). Forty-one (46.1%) URMs were reviewed at PMDC versus 71 (36.0%) non-URMs (p = 0.10). No differences in clinical and pathologic stage between the cohorts (p = 0.28) were present. URMs took 22 days longer on average to receive treatment (66.5 days vs. 44.8 days, p = 0.003) in the EP cohort and 18 days longer in OP cohort (58.0 days vs. 40.5 days, p < 0.001) compared with non-URMs. Pancreatic Multidisciplinary Clinic enrollment in EP cohort eliminated the difference in time to treatment between cohorts (48.3 days vs. 37.0 days; p = 0.151). RESULTS Underrepresented minorities were more likely to be diagnosed via EP and showed delayed times to treatment compared with non-URM counterparts. Our PMDC alleviated some of these observed disparities. Future studies are required to elucidate the specific factors that resulted in these findings and to identify solutions.

Abstract
PURPOSE Delays in oncologic time to treatment initiation (TTI) independently and adversely affect disease-specific mortality. Social Determinants of Health (SDoH) are increasingly recognized as significant contributors to patients' disease management and health outcomes. Our academic center has validated a 10-item SDoH screener, and we elucidated which specific needs may be predictive of delayed TTI. METHODS This is a retrospective cohort study at an urban academic center of patients with a SDoH screening and diagnosis of breast, colorectal, endocrine/neuroendocrine, GI, genitourinary, gynecologic, head and neck, hematologic, hepatobiliary, lung, or pancreatic cancer from 2018 to 2022. Variables of interest included household income, tumor stage, and emergency department (ED) or inpatient admission 30 days before diagnosis. Factors associated with delayed TTI ≥45 days were assessed using multivariable logistic regression. RESULTS Among 2,328 patients (mean [standard deviation] age, 64.0 (12.8) years; 66.6% female), having >1 unmet social need was associated with delayed TTI (odds ratio [OR], 1.68; 95% CI, 1.54 to 1.82). The disparities most associated with delay were legal help, transportation, housing stability, and needing to provide care for others. Those with ED (OR, 0.49; 95% CI, 0.44 to 0.54) or inpatient (OR, 0.54; 95% CI, 0.50 to 0.58) admission 30 days before diagnosis were less likely to experience delay. CONCLUSION Delays in oncologic TTI ≥45 days are independently associated with unmet social needs. ED or inpatient admissions before diagnosis increase care coordination, leading to improved TTI. Although limitations included the retrospective nature of the study and self-reporting bias, these findings more precisely identify targets for intervention that may more effectively decrease delay. Patients with SDoH barriers are at higher risk of treatment delay and could especially benefit from legal, transportation, caregiver, and housing assistance.

Abstract
Background: Pancreatic ductal adenocarcinoma (PDAC) presents significant challenges in diagnosis, staging, and appropriate treatment. Furthermore, patients with PDAC often experience complex symptomatology and psychosocial implications that require multi-disciplinary and inter-professional supportive care management from health professionals. Despite these hurdles, the implementation of inter-professional clinic approaches showed promise in enhancing clinical outcomes. To assess the effectiveness of such an approach, we examined the impact of the Wallace McCain Centre for Pancreatic Cancer (WMCPC), an inter-professional clinic for patients with PDAC at the Princess Margaret Cancer Centre (PM). Methods: This retrospective cohort study included all patients diagnosed with PDAC who were seen at the PM before (July 2012-June 2014) and after (July 2014-June 2016) the establishment of the WMCPC. Standard therapies such as surgery, chemotherapy, and radiation therapy remained consistent across both time periods. The cohorts were compared in terms of survival rates, disease stage, referral patterns, time to treatment, symptoms, and the proportion of patients assessed and supported by nursing and allied health professionals. Results: A total of 993 patients were included in the review, comprising 482 patients pre-WMCPC and 511 patients post-WMCPC. In the multivariate analysis, adjusting for ECOG (Eastern Cooperative Oncology Group) and stage, it was found that post-WMCPC patients experienced longer median overall survival (mOS, HR 0.84, 95% CI 0.72-0.98, p = 0.023). Furthermore, the time from referral to initial consultation date decreased significantly from 13.4 to 8.8 days in the post-WMCPC cohort (p < 0.001), along with a reduction in the time from the first clinic appointment to biopsy (14 vs. 8 days, p = 0.022). Additionally, patient-reported well-being scores showed improvement in the post-WMCPC cohort (p = 0.02), and these patients were more frequently attended to by nursing and allied health professionals (p < 0.001). Conclusions: The implementation of an inter-professional clinic for patients diagnosed with PDAC led to improvements in overall survival, patient-reported well-being, time to initial assessment visit and pathological diagnosis, and symptom management. These findings advocate for the adoption of an inter-professional clinic model in the treatment of patients with PDAC.

Abstract
The REDISCOVER guidelines present 34 recommendations for the selection and perioperative care of borderline-resectable (BR-PDAC) and locally advanced ductal adenocarcinoma of the pancreas (LA-PDAC). These guidelines represent a significant shift from previous approaches, prioritizing tumor biology over anatomical features as the primary indication for resection. Condensed herein, they provide a practical management algorithm for clinical practice. However, the guidelines also highlight the need to redefine LA-PDAC to align with modern treatment strategies and to solve some contradictions within the current definition, such as grouping "difficult" and "impossible" to resect tumors together. Furthermore, the REDISCOVER guidelines highlight several areas requiring urgent research. These include the resection of the superior mesenteric artery, the management strategies for patients with LA-PDAC who are fit for surgery but unable to receive multi-agent neoadjuvant chemotherapy, the approach to patients with LA-PDAC who are fit for surgery but demonstrate high serum Ca 19.9 levels even after neoadjuvant treatment, and the optimal timing and number of chemotherapy cycles prior to surgery. Additionally, the role of primary chemoradiotherapy versus chemotherapy alone in LA-PDAC, the timing of surgical resection post-neoadjuvant/primary chemoradiotherapy, the efficacy of ablation therapies, and the management of oligometastasis in patients with LA-PDAC warrant investigation. Given the limited evidence for many issues, refining existing management strategies is imperative. The establishment of the REDISCOVER registry ( https://rediscover.unipi.it/ ) offers promise of a unified research platform to advance understanding and improve the management of BR-PDAC and LA-PDAC.

Abstract
BACKGROUND Receipt of guideline-concordant treatment (GCT) is associated with improved prognosis in foregut cancers. Studies show that patients living in areas of high neighborhood deprivation have worse healthcare outcomes; however, its effect on GCT in foregut cancers has not been evaluated. We studied the impact of the area deprivation index (ADI) as a barrier to GCT. STUDY DESIGN A single-institution retrospective review of 498 foregut cancer patients (gastric, pancreatic, and hepatobiliary adenocarcinoma) from 2018 to 2022 was performed. GCT was defined based on National Comprehensive Cancer Network guidelines. ADI, a validated measure of neighborhood disadvantage was divided into terciles (low, medium, and high) with high ADI indicating the most disadvantage. RESULTS Of 498 patients, 328 (66%) received GCT: 66%, 72%, and 59% in pancreatic, gastric, and hepatobiliary cancers, respectively. Median (interquartile range) time from symptoms to workup was 6 (3 to 13) weeks, from diagnosis to oncology appointment was 4 (1 to 10) weeks, and from oncology appointment to treatment was 4 (2 to 10) weeks. Forty-six percent were diagnosed in the emergency department. On multivariable analyses, age 75 years or older (odds ratio [OR] 0.39 [95% CI 0.18 to 0.87]), Black race (OR 0.52 [95% CI 0.31 to 0.86]), high ADI (OR 0.25 (95% CI 0.14 to 0.48]), 6 weeks or more from symptoms to workup (OR 0.44 [95% CI 0.27 to 0.73]), 4 weeks or more from diagnosis to oncology appointment (OR 0.76 [95% CI 0.46 to 0.93]), and 4 weeks or more from oncology appointment to treatment (OR 0.63 [95% CI 0.36 to 0.98]) were independently associated with nonreceipt of GCT. CONCLUSIONS Residence in an area of high deprivation predicts nonreceipt of GCT. This is due to multiple individual- and system-level barriers. Identifying these barriers and developing effective interventions, including community outreach and collaboration, leveraging telehealth, and increasing oncologic expertise in underserved areas, may improve access to GCT.

Abstract
BACKGROUND As part of the Patient Protection and Affordable Care Act, some states expanded Medicaid eligibility to adults with incomes below 138% of the federal poverty line. While this resulted in an increased proportion of insured residents, its impact on the diagnosis and treatment of hepatopancreaticobiliary (HPB) cancers has not been studied. STUDY DESIGN The National Cancer Database (NCDB) from 2010 to 2017 was used. Patients diagnosed with HPB malignancies in states which expanded in 2014 were compared to patients in non-expansion states. Subset analyses of patients who underwent surgery and those in high-risk socioeconomic groups were performed. Outcomes studied included initiation of treatment within 30 days of diagnosis, stage at diagnosis, care at high volume or academic center, perioperative outcomes, and overall survival. Adjusted difference-in-differences analysis was performed. RESULTS A total of 345,684 patients were included, of whom 55% resided in non-expansion states and 54% were diagnosed with pancreatic cancer. Overall survival was higher in states with Medicaid expansion (HR .90, 95% CI [.88-.92], P < .01). There were also better postoperative outcomes including 30-day mortality (.67 [.57-.80], P < .01) and 30-day readmissions (.87 [.78-.97], P = .02) as well as increased likelihood of having surgery in a high-volume center (1.42 [1.32-1.53], P < .01). However, there were lower odds of initiating care within 30 days of diagnosis (.77 [.75-.80], P < .01) and higher likelihood of diagnosis with stage IV disease (1.09 [1.06-1.12], P < .01) in expansion states. CONCLUSION While operative outcomes and overall survival from HPB cancers were better in states with Medicaid expansion, there was no improvement in timeliness of initiating care or stage at diagnosis.

Abstract
Surgical resection is the only option to achieve long-term survival in cholangiocellular carcinoma (CCA). Due to limitations of health care systems and unforeseeable events, e.g., the COVID pandemic, the time from diagnosis to surgery (time-to-surgery (TTS)) has gained great interest in malignancies. Thus, we investigated whether TTS is associated with the oncological outcome in patients who underwent surgery for CCA. A cohort of 276 patients undergoing curative-intent surgery for intrahepatic and perihilar CCA excluding individuals with neoadjuvant therapy and perioperative mortality between 2010 and 2021 were eligible for analysis. Patients were grouped according to TTS (≤ 30; 31-60; 61-90; > 90 days) and compared by Kruskal-Wallis-analysis. Survival was compared using Kaplan-Meier analysis and characteristics associated with cancer-specific survival (CSS), recurrence-free survival (RFS) and overall survival (OS) using Cox regressions. The median CSS was 39 months (3-year-CSS = 52%, 5-year-CSS = 42%) and the median RFS 20 months (3-year-CSS = 38%, 5-year-CSS = 33%). In univariable Cox regressions, TTS was not associated with CSS (p = 0.971) or RFS (p = 0.855), respectively. A grouped analysis with respect to TTS (≤ 30 days, n = 106; 31-60 days, n = 134; 61-90 days, n = 44; > 90 days, n = 29) displayed a median CSS of 38, 33, 51 and 41 months and median RFS of 17, 22, 28 and 20 months (p = 0.971 log rank; p = 0.520 log rank). No statistical difference regarding oncological risk factors were observed between the groups. This study is the first comprehensive analysis of TTS in CCA patients. Within a representative European cohort, TTS was not associated with earlier tumor recurrence or reduced CCS.

Abstract
Pancreatic cancer is a malignant disease with a dismal prognosis. While neoadjuvant therapy has shown promise in the treatment of pancreatic cancer, its role remains a subject of controversy among physicians. We aimed to evaluate the benefits of neoadjuvant therapy in patients with resectable and borderline resectable pancreatic cancer. Eligible studies were identified from MEDLINE, Embase, Cochrane Library, and Web of Science. Studies comparing neoadjuvant therapy with upfront surgery (with or without adjuvant therapy) in resectable and borderline resectable pancreatic cancer were included. The primary endpoint assessed was overall survival. A total of 10,022 studies were identified, and the meta-analysis finally enrolled 50 revealed studies. The meta-analysis suggested that neoadjuvant therapy significantly improved the overall survival (HR 0.74, p < 0.001) and recurrence-free survival (HR 0.75, p = 0.006) compared to the upfront surgery approach. Furthermore, neoadjuvant therapy leads to favorable postoperative outcomes, with an enhanced R0 resection rate (OR 1.90, p < 0.001) and reduced lymph node metastasis (OR 0.36, p < 0.001) and perineural invasion (OR 0.42, p < 0.001), although it is associated with a reduced resection rate (OR 0.42, p < 0.001). In addition, patients treated with neoadjuvant therapy experience superior survival benefits compared to those undergoing adjuvant therapy (HR 0.87, p = 0.019). These results are further corroborated by the subgroup analysis of randomized controlled trials. Neoadjuvant therapy has the potential to provide survival benefits and improve postoperative long-term outcomes for patients with resectable and borderline resectable pancreatic cancer. However, to validate and reinforce these findings, further well-designed and large trials are required.

Abstract
Major sources of delay in the standard of care RT workflow are the need for multiple appointments and separate image acquisition. In this work, we addressed the question of how we can expedite the workflow by synthesizing planning CT from diagnostic CT. This idea is based on the theory that diagnostic CT can be used for RT planning, but in practice, due to the differences in patient setup and acquisition techniques, separate planning CT is required. We developed a generative deep learning model, deepPERFECT, that is trained to capture these differences and generate deformation vector fields to transform diagnostic CT into preliminary planning CT. We performed detailed analysis both from an image quality and a dosimetric point of view, and showed that deepPERFECT enabled the preliminary RT planning to be used for preliminary and early plan dosimetric assessment and evaluation.

Abstract
PURPOSE Given limitations of the health care systems in case of unforeseeable events, e.g., the COVID pandemic as well as trends in prehabilitation, time from diagnosis to surgery (time to surgery, (TTS)) has become a research issue in malignancies. Thus, we investigated whether TTS is associated with oncological outcome in HCC patients undergoing surgery. METHODS A monocentric cohort of 217 patients undergoing liver resection for HCC between 2009 and 2021 was analyzed. Individuals were grouped according to TTS and compared regarding clinical characteristics. Overall survival (OS) and recurrence-free survival (RFS) was compared using Kaplan-Meier analysis and investigated by univariate and multivariable Cox regressions. RESULTS TTS was not associated with OS (p=0.126) or RFS (p=0.761) of the study cohort in univariate analysis. In multivariable analysis age (p=0.028), ASA (p=0.027), INR (0.016), number of HCC nodules (p=0.026), microvascular invasion (MVI; p<0.001), and postoperative complications (p<0.001) were associated with OS and INR (p=0.005), and number of HCC nodules (p<0.001) and MVI (p<0.001) were associated with RFS. A comparative analysis of TTS subgroups was conducted (group 1, ≤30 days, n=55; group 2, 31-60 days, n=79; group 3, 61-90 days, n=45; group 4, >90 days, n=38). Here, the median OS were 62, 41, 38, and 40 months (p=0.602 log rank) and median RFS were 21, 26, 26, and 25 months (p=0.994 log rank). No statistical difference regarding oncological risk factors were observed between these groups. CONCLUSION TTS is not associated with earlier tumor recurrence or reduced overall survival in surgically treated HCC patients.

Abstract
Radical resection is the only curative treatment for pancreatic cancer. However, only up to 20% of patients are considered eligible for surgical resection at the time of diagnosis. Although upfront surgery followed by adjuvant chemotherapy has become the gold standard of treatment for resectable pancreatic cancer there are numerous ongoing trials aiming to compare the clinical outcomes of various surgical strategies (e.g., upfront surgery or neoadjuvant treatment with subsequent resection). Neoadjuvant treatment followed by surgery is considered the best approach in borderline resectable pancreatic tumors. Individuals with locally advanced disease are now candidates for palliative chemo- or chemoradiotherapy; however, some patients may become eligible for resection during the course of such treatment. When metastases are found, the cancer is qualified as unresectable. It is possible to perform radical pancreatic resection with metastasectomy in selected cases of oligometastatic disease. The role of multi-visceral resection, which involves reconstruction of major mesenteric veins, is well known. Nonetheless, there are some controversies in terms of arterial resection and reconstruction. Researchers are also trying to introduce personalized treatments. The careful, preliminary selection of patients eligible for surgery and other therapies should be based on tumor biology, among other factors. Such selection may play a key role in improving survival rates in patients with pancreatic cancer.

Abstract
PURPOSE Incremental delays in time to treatment initiation (TTI) have been shown to cause a proportional, increased independent risk of disease-specific mortality for breast cancer, colorectal cancer (CRC), head and neck cancer (HNC), non–small-cell lung cancer (NSCLC), and pancreatic cancer. Studies suggest that delays are associated with racial and socioeconomic disparities. We evaluated associations between patient factors and TTI to identify those associated with delay. MATERIALS AND METHODS This is a retrospective cohort study at an urban community-based academic center of patients diagnosed with or referred for curative-intent treatment of breast cancer, CRC, HNC, NSCLC, and pancreatic cancer from January 2019 to December 2021. Variables of interest included Charlson Comorbidity Index (CCI) score, insurance type, language preference, and inpatient admission 30 days before diagnosis. Factors associated with TTI delay, defined as TTI ≥ 30 days, were assessed using multivariable logistic regression. RESULTS Among 2,543 patients (69% female), the mean age was 63.4 years and the median TTI was 25 days (IQR, 6-44). Within multivariable models, patients treated as outpatient and not admitted 30 days before diagnosis experienced statistically significant greater delay for CRC (odds ratio [OR], 2.82; 95% CI, 1.71 to 4.66) and NSCLC (OR, 2.11; 95% CI, 1.31 to 3.39). Higher CCI score was associated with delay for HNC (OR, 2.63; 95% CI, 1.04 to 6.66) and NSCLC (OR, 1.75; 95% CI, 1.14 to 2.71). For breast cancer, uninsured and Spanish-speaking patients (OR, 1.79; 95% CI, 1.21 to 2.67) experienced increased TTI. CONCLUSION Care coordination/compliance (eg, inpatient 30 days before diagnosis), clinical (eg, medical comorbidities), and socioeconomic (eg, uninsured status) predictors for delayed TTI were identified and may inform delay minimizing interventions. Our data support evidence that TTI delays are associated with demographic and socioeconomic disparities. Existing disparities are likely exacerbated by delays that disproportionately affect patients with care coordination/compliance issues, multiple comorbidities, and lower socioeconomic status.

Abstract
Pancreatic cancer with more than 60,000 new cases each year has less than 10 percent 5-year overall survival. Radiation therapy (RT) is an effective treatment for Locally advanced pancreatic cancer (LAPC). The current clinical RT workflow is lengthy and involves separate image acquisition for diagnostic CT (dCT) and planning CT (pCT). Studies have shown a reduction in mortality rate from expeditious radiotherapy treatment. dCT and pCT are acquired separately because of the differences in the image acquisition setup and patient body. We are presenting deepPERFECT: deep learning-based model to adapt the shape of the patient body on dCT to the treatment delivery setup. Our method expedites the treatment course by allowing the design of the initial RT planning before the pCT acquisition. Thus, the physicians can evaluate the potential RT prognosis ahead of time, verify the plan on the treatment day-one CT and apply any online adaptation if needed. We used the data from 25 pancreatic cancer patients. The model was trained on 15 cases and tested on the remaining ten cases. We evaluated the performance of four different deep-learning architectures for this task. The synthesized CT (sCT) and regions of interest (ROIs) were compared with ground truth (pCT) using Dice similarity coefficient (DSC) and Hausdorff distance (HD). We found that the three-dimensional Generative Adversarial Network (GAN) model trained on large patches has the best performance. The average DSC and HD for body contours were 0.93, and 4.6 mm. We found no statistically significant difference between the synthesized CT plans and the ground truth. We showed that employing deepPERFECT shortens the current lengthy clinical workflow by at least one week and improves the effectiveness of treatment and the quality of life of pancreatic cancer patients.

Abstract
OBJECTIVES The role of concomitant chemoradiotherapy or radiotherapy (RT) after induction chemotherapy (IC) in borderline resectable and locally advanced pancreatic ductal adenocarcinoma is debatable. This systematic review aimed to explore this. METHODS We searched PubMed, MEDLINE, EMBASE, and Cochrane database. Studies were selected reporting outcomes on resection rate, R0 resection, pathological response, radiological response, progression-free survival, overall survival, local control, morbidity, and mortality. RESULTS The search resulted in 6635 articles. After 2 rounds of screening, 34 publications were selected. We found 3 randomized controlled studies and 1 prospective cohort study, and the rest were retrospective studies. There is consistent evidence that addition of concomitant chemoradiotherapy or RT after IC improves pathological response and local control. There are conflicting results in terms of other outcomes. CONCLUSIONS Concomitant chemoradiotherapy or RT after IC improves local control and pathological response in borderline resectable and locally advanced pancreatic ductal adenocarcinoma. The role of modern RT in improving other outcome requires further research.

Abstract
Background: Excessive waiting time intervals for the diagnosis and treatment of patients with pancreatic cancer can influence their prognosis but they remain unclear. The objective was to describe time intervals from the medical visit to diagnostic imaging and to treatment and their prognostic impact in pancreatic cancer in one French region. Methods: This retrospective observational multicentre study included all patients with pancreatic cancer seen for the first time in 2017 in multidisciplinary team meetings (MTMs), where clinical data were collected. A probabilistic matching with the medico-administrative data from the French national healthcare database (Système National des Données de Santé) was performed to define the care pathway from clinical presentation to the beginning of treatment. Median key time intervals were estimated for both resected and unresected tumours. Factors associated with 1-year survival were studied using Cox model. Results: A total of 324 patients (88% of total patients with MTM presentation) were matched and included: male 54%, mean age 72 years ±9.2, Eastern Cooperative Oncology Group (ECOG) PS > 1 19.5%, metastatic disease at diagnosis 47.4%, tumour resection 16%. At 1 year, 57% had died (65% in the unresected group and 17% in the resected group). The median time interval from the medical visit to diagnostic imaging was 15 days [Q1–Q3: 8–44]. After imaging, median time intervals to definite diagnosis and to first treatment were 11 and 20 days, respectively. Significant prognostic factors associated with the risk of death at 1 year were ECOG PS > 1 (hazard ratio (HR) 2.1 [1.4–3.0]), metastasis (HR 2.7 [1.9–3.9]), no tumour resection (HR 2.7 [1.3–5.6]) and time interval between the medical visit and diagnostic imaging ⩾25 days (HR 1.7 [1.2–2.3]). Conclusion: Delay in access to diagnostic imaging impacted survival in patients with pancreatic cancer, regardless of whether tumour resection had been performed.

Abstract
BACKGROUND The initiation of adjuvant chemotherapy for pancreatic adenocarcinoma within 12 weeks after surgery is recommended by the National Comprehensive Cancer Network. This study seeks to identify factors associated with delayed adjuvant chemotherapy and whether delays impact survival in under-resourced populations. METHODS Patients with nonmetastatic pancreatic adenocarcinoma who received a definitive resection followed by adjuvant chemotherapy between 2006 and 2017 were queried from the National Cancer Database. Multivariate logistic regression models were constructed to determine the relationship between socioeconomic/clinical variables and delayed adjuvant chemotherapy. Kaplan Meier curves compared survival between under-resourced patients receiving delayed versus timely adjuvant chemotherapy. RESULTS Among 25,008 patients, timely adjuvant chemotherapy varied by stage (stage 1: 67.9% vs stage 2: 75.8% vs stage 3: 89.2%; P < .001). Older age (odds ratio 1.02, 95% confidence interval 1.02-1.03; P < .001), Non-Hispanic Black race (odds ratio 1.25, 95% confidence interval 1.11-1.41; P < .001), increasing comorbidity score (odds ratio 1.18, 95% confidence interval 1.12-1.23; P < .001), 30-day readmission (odds ratio 1.45, 95% confidence interval 1.28-1.63; P < .001), and undergoing a Whipple (odds ratio 1.30, 95% confidence interval 1.16-1.44; P < .001) were associated with delayed adjuvant chemotherapy. Conversely, the highest neighborhood median income quartile (odds ratio 0.84, 95% confidence interval 0.73-0.97; P = .021), private insurance (odds ratio 0.59, 95% confidence interval 0.46-0.76; P < .001), Medicare (odds ratio 0.68, 95% confidence interval 0.52-0.88; P = .003), and receipt of neoadjuvant therapy (odds ratio 0.05, 95% confidence interval 0.04-0.06; P < .001) were associated with timely adjuvant chemotherapy. Non-Hispanic Black patients and patients with the lowest neighborhood education had worse overall survival when receiving delayed versus timely adjuvant chemotherapy. CONCLUSION Timely adjuvant chemotherapy for pancreatic adenocarcinoma was only achieved in 73.3% of patients. Age, race, comorbidities, median income, and insurance were identified as barriers. Delayed adjuvant chemotherapy was associated with worse survival among under-resourced populations.

Abstract
PURPOSE We evaluated how race and socioeconomic factors impact access to high-volume surgical centers, treatment initiation, and postoperative care for pancreatic cancer in a state with robust safety net insurance coverage and healthcare infrastructure. METHODS The New York Statewide Planning and Research Cooperative System was analyzed. Patients with pancreatic cancer resected from 2007 to 2017 were identified by ICD and CPT codes. Primary outcomes included surgery at low-volume facilities (< 20 pancreatectomies/year), time to therapy initiation, and time to postoperative surveillance imaging (within 60-180 days after surgery). RESULTS In total, 3312 patients underwent pancreatectomy across 124 facilities. Median age was 67 years (IQR 59, 75) and 55% of patients were male. Most (72.7%) had surgery at high-volume centers. On multivariable analysis, odds ratios for surgery at low-volume centers were increased for Black race (2.21 (95% CI 1.69-2.88)), Asian race (1.64 (95% CI 1.09-2.43)), Hispanic ethnicity (1.68 (95% CI 1.24-2.28)), Medicaid insurance (2.52 (95% CI 1.79-3.56)), no insurance (2.24 (95% CI 1.38-3.61)), lowest income quartile (3.31 (95% CI 2.14-5.32)), and rural zip code (2.49 (95% CI 1.69-3.65)). Patients treated at low-volume centers waited longer to initiate treatment (hazard ratio (HR) 0.91 (95% CI 0.81-1.01)). Black patients underwent the least surveillance imaging (50.4%; p < 0.0001), while Asian (HR 2.04, 95% CI 1.40-2.98)) and Hispanic patients (HR 1.36 (95% CI 1.00-1.84)) were more likely to have surveillance imaging. CONCLUSIONS Race independently affected access to high-volume facilities and surveillance imaging. When considered in light of other accumulating evidence, future efforts might investigate the perceptions and logistical considerations noted by providers and patients alike to identify the etiology of these disparities and then institute corrective measures.

Abstract
INTRODUCTION Not all patients with pancreatic adenocarcinoma (PDAC) tolerate multiagent neoadjuvant chemotherapy (NAC). We utilized institutional data and the National Cancer Database (NCDB) to investigate if time from diagnosis to NAC initiation is associated with survival. METHODS Patients who received NAC and underwent pancreatectomy at our institution (2010-2021) or within the NCDB (2010-2016) were identified. Time from diagnosis to NAC was grouped: <21, 21-35, and >35 d. Recurrence-free (RFS) and overall survival (OS) was compared. RESULTS At our institution, 122 patients received NAC before pancreatectomy (<21 d: n = 36; 21-35 d: n = 61; >35 d: n = 25). Demographics, performance status, and anatomic resectability were similar. There was no difference in RFS (13.3 versus 12.4 versus 11.9 mo) or OS (26.7 versus 25.8 versus 26.1 mo) based on NAC timing. Patients who received FOLFIRINOX had an improvement in RFS (14.4 versus 12.2 versus 6.8 mo, P = 0.05) and OS (39.2 versus 21.4 versus 17.3 mo, P = 0.01) compared to gemcitabine with nab-paclitaxel or other regimens. Within the NCDB, 6713 patients were included (<21 d: n = 2087; 21-35 d: n = 2656; >35 d: n = 1970). There was no difference in OS (21.6 versus 20.9 versus 22.2 mo). Multiagent NAC was associated with improved OS compared to single-agent (22.6 versus 18.8 mo, P < 0.001). CONCLUSIONS Delay in NAC initiation for PDAC is not associated with survival. Patient optimization could be considered with the goal of improving tolerance of multiagent chemotherapy.

Abstract
An important goal of cancer surgery is to achieve negative surgical margins and remove all disease completely. For pancreatic neoplasms, microscopic margins may remain positive despite gross removal of the palpable mass, and surgeons must then consider extending resection, even to the point of completion pancreatectomy, an option that renders the patient with significant adverse effects related to exocrine and endocrine insufficiency. Counterintuitively, extending resection to ensure clear margins may not improve patient outcome. Furthermore, the goal of improving survival by extending the resection may not be achieved, as an initial positive margin may indicate more aggressive underlying tumor biology. There is a growing body of literature on this topic, and this landmark series review will examine the key publications that guide our management for resection of pancreatic ductal adenocarcinoma, intraductal papillary mucinous neoplasms, and pancreatic neuroendocrine tumors.

Abstract
Extradomain-B Fibronectin (EDB-FN) is an oncomarker that can be visualized with magnetic resonance molecular imaging (MRMI) to detect pancreatic ductal adenocarcinoma (PDAC) metastasis. In this study, we sought to assess the expression of EDB-FN in clinical samples of PDAC and to evaluate MRMI of PDAC metastasis with an EDB-FN-specific gadolinium-based contrast agent (MT218) in an orthotopic KPC-GFP-Luc mouse model. EDB-FN expression was evaluated in PDAC tissue samples through immunohistochemistry. RNA-Seq data obtained from the GEPIA2 project was evaluated to demonstrate EDB-FN expression in large patient cohorts. FLASH-3D MRI at 3 T of the KPC-GFP-Luc metastasis model was performed following injection of MT218. Tumor enhancement in MR images was correlated to postmortem distribution of KPC-GFP-Luc tumors using fluorescent and bright-field cryo-imaging and anatomical landmarks. EDB-FN immunohistochemical staining scores of human metastatic tumor stroma, (2.17 ± 0.271), metastatic tumor parenchyma (2.08 ± 0.229), primary tumor stroma (1.61 ± 0.26), and primary tumor parenchyma (1.61 ± 0.12) were significantly (p < 0.0001) higher than normal pancreas stroma (0.14 ± 0.10) and normal pancreas parenchyma (0.14 ± 0.14). EDB-FN mRNA expression in tumors is 4.98 log2(TPM + 1) and 0.18 log2(TPM + 1) in normal tissue (p < 0.01). A mouse model of EDB-FN rich PDAC metastasis exhibited T1-weighted contrast to noise (CNR) changes of 21.80 ± 4.34 in perimetastatic regions and 8.38 ± 0.79 in metastatic regions identified through cryo-imaging, significantly higher (p < 0.05) than CNR changes found in normal liver (-6.43 ± 0.92), mesentery (2.24 ± 0.92), spleen (-3.06 ± 2.38) and intestine (1.08 ± 2.15). We conclude that EDB-FN is overexpressed in metastatic and primary PDAC tumors and MRMI with MT218 enables the detection of metastatic and perimetastatic tissues.

Abstract
Pancreatic cancer is one of the solid tumors with the worst prognosis. Five-year survival rate is less than 10%. Surgical resection is the only potentially curative treatment, but the tumor is often diagnosed at an advanced stage of the disease and surgery could be performed in a very limited number of patients. Moreover, surgery is still associated with high post-operative morbidity, while other therapies still offer very disappointing results. This article reviews every aspect of pancreatic cancer, focusing on the elements that can improve prognosis. It was written with the aim of describing everything you need to know in 2021 in order to face this difficult challenge.

Abstract
The high mortality of pancreatic cancer is attributed to the insidious progression of this disease, which results in a delayed diagnosis and advanced disease stage at diagnosis. More than 35% of patients with pancreatic cancer are in stage III, whereas 50% are in stage IV at diagnosis. Thus, understanding the aggressive features of pancreatic cancer will contribute to the resolution of problems, such as its early recurrence, metastasis, and resistance to chemotherapy and radiotherapy. Therefore, new therapeutic strategies targeting tumor suppressor gene products may help prevent the progression of pancreatic cancer. In this review, we discuss several recent clinical trials of pancreatic cancer and recent studies reporting safe and effective treatment modalities for patients with advanced pancreatic cancer.

Abstract
BACKGROUND Patients can experience barriers and disparities to access high-quality cancer care. This study sought to characterize receipt of surgery and chemotherapy among Medicare beneficiaries with a diagnosis of early-stage pancreatic adenocarcinoma cancer (PDAC) relative to race/ethnicity and social vulnerability. METHODS The Surveillance, Epidemiology, and End Results (SEER)-Medicare database was used to identify patients with a diagnosis of early-stage (stage 1 or 2) PDAC between 2004 and 2016. Data were merged with the CDC's Social Vulnerability Index (SVI) at the beneficiary's county of residence. Multivariable, mixed-effects logistic regression was used to assess the association of SVI with resection. RESULTS Among 15,931 older Medicare beneficiaries with early-stage PDAC (median age, 77 years; interquartile range [IQR], 71-82 years), the majority was White (n = 12,737, 80.0 %), whereas a smaller subset was Black or Latino (n = 3194, 20.0 %) A minority of patients was more likely to live in highly vulnerable communities (low SVI: white [90.5 %] vs minority [9.5 %] vs high SVI: white [71.9 %] vs minority [28.1 %]; p < 0.001). Use of resection for early-stage PDAC was lowest among the patients who resided in high-SVI areas (low [38.0 %] vs average [34.3 %] vs high [31.9 %]; p < 0.001). The minority patients were less likely to undergo resection than the White patients (no resection: white [64.1 %] vs minority [70.7 %]; p < 0.001). The median SVI was higher among the patients who underwent resection (57.6; IQR, 36.0-81.0) than among those who did not (60.4; IQR, 41.9-84.3), and increased SVI resulted in a decline in the likelihood of resection (SVI trend: OR, 0.98; 95 % confidence interval [CI], 0.97-1.00), especially among the minority patients. Minority patients from high-SVI counties had markedly lower odds of preoperative chemotherapy than minority patients from a low-SVI neighborhood (OR, 0.62; 95 % CI, 0.52-0.73). CONCLUSIONS Older Medicare beneficiaries with early-stage PDAC residing in counties with higher social vulnerability had lower odds of undergoing pancreatic resection, which was more pronounced among minority versus older White Medicare beneficiaries.

Søreide K. Neoadjuvant and Adjuvant Therapy in Operable Pancreatic Cancer: Both Honey and Milk (but No Bread?). Oncol Ther 2021; 9:1-12. [PMID: 33439449 PMCID: PMC8140001 DOI: 10.1007/s40487-020-00136-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 12/18/2020] [Indexed: 12/20/2022] Open
Abstract
Pancreatic cancer has a dismal prognosis. Resection is the best option for cure, supported by multimodal therapy to treat the systemic disease. While adjuvant therapy has become standard in those who are fit and who can tolerate the given regimen, the concept of perioperative (neoadjuvant) therapy is building momentum. The concepts of “borderline” and “locally advanced” have changed the previous dichotomized “resectable/non-resectable” into subcategories for which new algorithms have emerged, with neoadjuvant therapy discussed both for upfront resectable pancreatic cancer, for those deemed borderline resectable, and as “induction or conversion” therapy for locally advanced disease. The purpose of this invited commentary is to discuss some of the changing paradigms in multimodal therapy for operable pancreatic cancer. The PREOPANC trial presented randomized data on the role of neoadjuvant therapy for resectable and borderline cancers, but new questions have emerged. The role of combination therapy in the preoperative setting is discussed in the light of this trial. FOLFIRINOX has emerged as the most potent treatment regimen in the metastatic and adjuvant setting, but with no level I data to support neoadjuvant use yet. Several trials are ongoing to arrive at the best answer.

J Surg Oncol 2020; 123:236-244. [PMID: 33084065 DOI: 10.1002/jso.26266] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2020] [Revised: 10/01/2020] [Accepted: 10/05/2020] [Indexed: 11/08/2022]
Abstract
INTRODUCTION The objective of this study was to characterize time from cancer symptoms to diagnosis and time from diagnosis to surgical treatment among patients undergoing pancreatectomy for cancer. METHODS Medicare beneficiaries who underwent pancreatectomy for cancer between 2013 and 2017 were identified using the 100% Medicare Inpatient Standard Analytic Files. Mixed effects negative binomial regression models were utilized to determine which factors were associated with the number of weeks to diagnosis and pancreatic resection. RESULTS Among 7647 Medicare beneficiaries, two-thirds (n = 5127, 67%) had symptoms associated with a pancreatic cancer diagnosis before surgery. Median time from the first symptom to diagnosis was 6 weeks (IQR: 1-25) and the median time from diagnosis to surgery was 4 weeks (IQR: 2-15). In risk-adjusted models, female patients had 13% longer waiting times from identification of a related symptom to pancreatic cancer diagnosis (OR = 1.13, 95% CI: 1.05-1.21) and 12% longer waiting times from diagnosis to surgery (OR = 1.12, 95% CI: 1.07-1.18). Older age was associated with 10% longer waiting times from symptom identification to diagnosis (p < .0001). CONCLUSIONS Female and older patients had longer wait times between symptom presentation and pancreatic cancer diagnosis. Sex-based disparities in cancer care need to be recognized and addressed by policymakers and health care institutions.
