1 Review Advances in Molecular Pathology and Treatment of Periampullary Cancers. 2016

Chandrasegaram, Manju D / Chen, John W / Price, Timothy J / Zalcberg, John / Sjoquist, Katrin / Merrett, Neil D. ·From the *NHMRC Clinical Trials Centre; †Department of Surgery, The Prince Charles Hospital, Brisbane; ‡Department of Surgery, Flinders Medical Centre; §Queen Elizabeth Hospital, Adelaide; ∥University of Adelaide, South Australia; ¶School of Public Health and Preventive Medicine, Faculty of Medicine, Nursing and Health Sciences, Monash University, Melbourne; #Cancer Care Centre, Department of Medical Oncology, St George Hospital; **Department of Surgery, Bankstown Hospital; and ††Division of Surgery, University of Western Sydney, Sydney, Australia. ·Pancreas · Pubmed #26348463.

ABSTRACT: OBJECTIVES: Periampullary cancers (PACs) include the following 4 traditional anatomic subtypes: pancreatic, ampullary, biliary, or duodenal cancers. This review was performed to highlight recent advances in the genomic and molecular understanding of each PAC subtype and the advances in chemotherapeutic and molecular trials in these cancer subtypes. RESULTS: Recent advances have highlighted differences in the genomic and molecular features within each PAC subtype. Ampullary cancers can now be further defined accurately into their intestinal and pancreatobiliary subtypes using histomolecular profiling. K-ras mutation, which occurs in most pancreatic cancers, is found to occur less frequently in ampullary (42%-52%), biliary (22%-23%), and duodenal cancers (32%-35%), suggesting crucial differences in targetable mutations in these cancer subtypes.Ampullary cancers of intestinal subtype and duodenal cancers seem to share similarities with colorectal cancer, given that they respond to similar chemotherapeutic regimens. This has potential implications for clinical trials and treatment selection, where PACs are often considered together. CONCLUSIONS: Future trials should be designed in view of our increased understanding of the different anatomic and histomolecularly profiled subtypes of PAC cancers, which respects their individual molecular characteristics, phenotype, and response to treatment.

ABSTRACT: BACKGROUND: R0 resection rates (complete tumour removal with negative resection margins) in pancreatic cancer are 70-80 per cent when a 0-mm margin is used, declining to 15-24 per cent with a 1-mm margin. This review evaluated the R0 resection rates according to different margin definitions and techniques. METHODS: Three databases (MEDLINE from 1946, PubMed from 1946 and Embase from 1949) were searched to mid-October 2014. The search terms included 'pancreatectomy OR pancreaticoduodenectomy' and 'margin'. A meta-analysis was performed with studies in three groups: group 1, axial slicing technique (minimum 1-mm margin); group 2, other slicing techniques (minimum 1-mm margin); and group 3, studies with minimum 0-mm margin. RESULTS: The R0 rates were 29 (95 per cent c.i. 26 to 32) per cent in group 1 (8 studies; 882 patients) and 49 (47 to 52) per cent in group 2 (6 studies; 1568 patients). The combined R0 rate (groups 1 and 2) was 41 (40 to 43) per cent. The R0 rate in group 3 (7 studies; 1926 patients) with a 0-mm margin was 72 (70 to 74) per cent The survival hazard ratios (R1 resection/R0 resection) revealed a reduction in the risk of death of at least 22 per cent in group 1, 12 per cent in group 2 and 23 per cent in group 3 with an R0 compared with an R1 resection. Local recurrence occurred more frequently with an R1 resection in most studies. CONCLUSION: Margin clearance definitions affect R0 resection rates in pancreatic cancer surgery. This review collates individual studies providing an estimate of achievable R0 rates, creating a benchmark for future trials.

3 Review Role of endoscopic ultrasound in pancreatic cancer. 2009

Chang, David K / Nguyen, Nam Q / Merrett, Neil D / Dixson, Hugh / Leong, Rupert W L / Biankin, Andrew V. ·Department of Surgery, Bankstown Hospital, Bankstown, NSW 2200, Australia. ·Expert Rev Gastroenterol Hepatol · Pubmed #19485810.

ABSTRACT: Pancreatic cancer (PC) is the fourth most common cause of cancer deaths in Western societies. It is an aggressive tumor with an overall 5-year survival rate of less than 5%. Surgical resection offers the only possibility of cure and long-term survival for patients suffering from PC; however, unfortunately, fewer than 20% of patients suffering from PC have disease that is amendable to surgical resection. Therefore, it is important to accurately diagnose and stage these patients to enable optimal treatment of their disease. The imaging modalities involved in the diagnosis and staging of PC include multidetector CT scanning, endoscopic ultrasound (EUS), endoscopic retrograde cholangiopancreaticography and MRI. The roles and relative importance of these imaging modalities have changed over the last few decades and continue to change owing to the rapid technological advances in medical imaging, but these investigations continue to be complementary. EUS was first introduced in the mid-1980s in Japan and Germany and has quickly gained acceptance. Its widespread use in the last decade has revolutionized the management of pancreatic disease as it simultaneously provides primary diagnostic and staging information, as well as enabling tissue biopsy. This article discusses the potential benefits and drawbacks of EUS in the primary diagnosis, staging and assessment of resectability, and EUS-guided fine-needle aspiration in PC. Difficult diagnostic scenarios and pitfalls are also discussed. A suggested management algorithm for patients with suspected PC is also presented.

ABSTRACT: AIM: Palliative chemotherapy improves symptom control and prolongs survival in patients with unresectable pancreatic cancer, but there is a paucity of data describing its use and effectiveness in everyday practice. We explored patterns of chemotherapy use in patients with unresected pancreatic cancer in Australia and the impact of use on survival. METHODS: We reviewed the medical records of residents of New South Wales or Queensland, Australia, diagnosed with unresectable pancreatic adenocarcinoma between July 2009 and June 2011. Associations between receipt of chemotherapy and sociodemographic, clinical and health service factors were evaluated using logistic regression. We used Cox proportional hazards models to analyze associations between chemotherapy use and survival. RESULTS: Data were collected for 1173 eligible patients. Chemotherapy was received by 44% (n = 184/414) of patients with localized pancreatic cancer and 53% (n = 406/759) of patients with metastases. Chemotherapy receipt depended on clinical factors, such as performance status and comorbidity burden, and nonclinical factors, such as age, place of residence, multidisciplinary team review and the type of specialist first encountered. Consultation with an oncologist mitigated most of the sociodemographic and service-related disparities in chemotherapy use. The receipt of chemotherapy was associated with prolonged survival in patients with inoperable pancreatic cancer, including after adjusting for common prognostic factors. CONCLUSIONS: These findings highlight the need to establish referral pathways to ensure that all patients have the opportunity to discuss treatment options with a medical oncologist. This is particularly relevant for health care systems covering areas with a geographically dispersed population.

5 Article Biliary Stenting in Patients With Pancreatic Cancer: Results From a Population-Based Cohort Study. 2018

Payne, Madeleine / Burmeister, Elizabeth A / Waterhouse, Mary / Jordan, Susan J / OʼConnell, Dianne L / Merrett, Neil D / Goldstein, David / Wyld, David / Beesley, Vanessa L / Gooden, Helen / Janda, Monika / Neale, Rachel E. · ·Pancreas · Pubmed #29215539.

ABSTRACT: OBJECTIVE: We aimed to describe management of biliary obstruction (BO) in the context of pancreatic cancer within a population-based cohort. METHODS: We examined management of BO in 1863 patients diagnosed as having pancreatic cancer in 2010/2011. We used descriptive statistics and logistic regression to describe patterns of biliary stent usage, complications and duration of patency, associations between preoperative stenting and surgical outcomes, and between patient factors and management of jaundice. RESULTS: Almost half of the people in the cohort (n = 909) were jaundiced within 12 months of diagnosis. Two-thirds of these had at least 1 stent inserted. Preoperative stenting, mostly with plastic stents, occurred for 72% of patients who experienced jaundice prior to an attempted resection but was not associated with surgical outcomes. Seventy percent of the jaundiced patients who did not have an attempted resection were stented. Metal stents were less frequently replaced within 30 days than plastic (9% vs 42%). Living in a rural area was associated with reduced likelihood of having jaundice managed. CONCLUSIONS: Plastic stents were still used frequently, despite guidelines recommending metal in most contexts. Patients living in rural areas were less likely to have BO managed. This work highlights the need to monitor current practice.

6 Article Association between pancreatic cancer patients' perception of their care coordination and patient-reported and survival outcomes. 2018

ABSTRACT: OBJECTIVE: People with pancreatic cancer have poor survival, and management is challenging. Pancreatic cancer patients' perceptions of their care coordination and its association with their outcomes have not been well-studied. Our objective was to determine if perception of care coordination is associated with patient-reported outcomes or survival. METHODS: People with pancreatic cancer who were 1-8 months postdiagnosis (52 with completed resection and 58 with no resection) completed a patient-reported questionnaire that assessed their perceptions of care coordination, quality of life, anxiety, and depression using validated instruments. Mean scores for 15 care-coordination items were calculated and then ranked from highest (best experience) to lowest (worst experience). Associations between care-coordination scores (including communication and navigation domains) and patient-reported outcomes and survival were investigated using general linear regression and Cox regression, respectively. All analyses were stratified by whether or not the tumor had been resected. RESULTS: In both groups, the highest-ranked care-coordination items were: knowing who was responsible for coordinating care, health professionals being informed about their history, and waiting times. The worst-ranked items related to: how often patients were asked about visits with other health professionals and how well they and their family were coping, knowing the symptoms they should monitor, having sufficient emotional help from staff, and access to additional specialist services. For people who had a resection, better communication and navigation scores were significantly associated with higher quality of life and less anxiety and depression. However, these associations were not statistically significant for those with no resection. Perception of cancer care coordination was not associated with survival in either group. SIGNIFICANCE OF RESULTS: Our results suggest that, while many core clinical aspects of care are perceived to be done well for pancreatic cancer patients, improvements in emotional support, referral to specialist services, and self-management education may improve patient-reported outcomes.

ABSTRACT: BACKGROUND: The return of research results (RoR) remains a complex and well-debated issue. Despite the debate, actual data related to the experience of giving individual results back, and the impact these results may have on clinical care and health outcomes, is sorely lacking. Through the work of the Australian Pancreatic Cancer Genome Initiative (APGI) we: (1) delineate the pathway back to the patient where actionable research data were identified; and (2) report the clinical utilisation of individual results returned. Using this experience, we discuss barriers and opportunities associated with a comprehensive process of RoR in large-scale genomic research that may be useful for others developing their own policies. METHODS: We performed whole-genome (n = 184) and exome (n = 208) sequencing of matched tumour-normal DNA pairs from 392 patients with sporadic pancreatic cancer (PC) as part of the APGI. We identified pathogenic germline mutations in candidate genes (n = 130) with established predisposition to PC or medium-high penetrance genes with well-defined cancer associated syndromes or phenotypes. Variants from candidate genes were annotated and classified according to international guidelines. Variants were considered actionable if clinical utility was established, with regard to prevention, diagnosis, prognostication and/or therapy. RESULTS: A total of 48,904 germline variants were identified, with 2356 unique variants undergoing annotation and in silico classification. Twenty cases were deemed actionable and were returned via previously described RoR framework, representing an actionable finding rate of 5.1%. Overall, 1.78% of our cohort experienced clinical benefit from RoR. CONCLUSION: Returning research results within the context of large-scale genomics research is a labour-intensive, highly variable, complex operation. Results that warrant action are not infrequent, but the prevalence of those who experience a clinical difference as a result of returning individual results is currently low.

ABSTRACT: The diagnosis of pancreatic neuroendocrine tumours (PanNETs) is increasing owing to more sensitive detection methods, and this increase is creating challenges for clinical management. We performed whole-genome sequencing of 102 primary PanNETs and defined the genomic events that characterize their pathogenesis. Here we describe the mutational signatures they harbour, including a deficiency in G:C > T:A base excision repair due to inactivation of MUTYH, which encodes a DNA glycosylase. Clinically sporadic PanNETs contain a larger-than-expected proportion of germline mutations, including previously unreported mutations in the DNA repair genes MUTYH, CHEK2 and BRCA2. Together with mutations in MEN1 and VHL, these mutations occur in 17% of patients. Somatic mutations, including point mutations and gene fusions, were commonly found in genes involved in four main pathways: chromatin remodelling, DNA damage repair, activation of mTOR signalling (including previously undescribed EWSR1 gene fusions), and telomere maintenance. In addition, our gene expression analyses identified a subgroup of tumours associated with hypoxia and HIF signalling.

ABSTRACT: BACKGROUND: People with pancreatic cancer have high levels of anxiety and depression and reduced quality of life (QoL), but few studies have assessed these outcomes for patient-carer dyads. We therefore investigated these issues in an Australian population-based study. METHODS: Patients with pancreatic cancer (n = 136) and many of their carers (n = 84) completed the Hospital Anxiety and Depression Scale (HADS) and Functional Assessment of Cancer Therapy QoL questionnaire at a median of three months after diagnosis. Overall QoL and well-being subscales (physical, social, emotional, functional) were compared with general population norms. Intraclass correlation coefficients were used to compare anxiety, depression and QoL scores of patients and their respective carers. RESULTS: Fifteen percent of patients and 39% of carers had HADS scores indicative of anxiety and 15% of patients and 14% of carers of depression, respectively. Overall, 70% of patients and 58% of carers had QoL scores below the Queensland population average. Patients' anxiety, depression, overall QoL, social, emotional and functional wellbeing scores were significantly related to those scores in their carers. Among patients and carers, accessing psychological help was associated with elevated anxiety. Not receiving chemotherapy was associated with elevated depression among patients and younger age was associated with poorer outcomes in carers. CONCLUSIONS: More carers had symptoms of anxiety than patients with pancreatic cancer, but symptoms of depression were similarly common in patients and carers. Further research is needed to assess whether interventions to reduce patients' distress could also improve QoL among carers, or whether carer-focussed interventions are required.

ABSTRACT: OBJECTIVE: To examine differences in the proportions of people diagnosed with pancreatic cancer who underwent pancreatectomy, post-operative outcomes and 5-year survival in different New South Wales administrative health regions of residence. DESIGN, SETTING AND PARTICIPANTS: Retrospective analysis of NSW data on pancreatic cancer incidence and surgery, 2005-2013. MAIN OUTCOME MEASURES: The proportion of newly diagnosed patients with pancreatic cancer who were resected in each region; 90-day post-operative mortality; one-year post-operative survival; 5-year post-diagnosis survival. RESULTS: 14% of people diagnosed with pancreatic cancer during 2010-2013 (431 of 3064) underwent pancreatectomy, an average of 108 resections per year. After adjusting for age, sex and comorbidities, the proportion that underwent resection varied significantly between regions, ranging between 8% and 21% (P<0.001). Higher resection rates were not associated with higher post-operative 90-day mortality or lower one-year survival (unadjusted and risk-adjusted analyses). Higher resection rates were associated with higher 5-year post-diagnosis survival: the mean survival in regions with resection rates below 10% was 3.4%, compared with 7.2% in regions with rates greater than 15% (unadjusted and adjusted survival analyses; P<0.001). There was a positive association between regional resection rate and the pancreatectomy volume of hospitals during 2005-2009. An additional 32 people would be resected annually if resection rates in low rate regions were increased to the 80th percentile regional resection rate (18%). CONCLUSION: There is significant geographic variation in the proportion of people with pancreatic cancer undergoing pancreatectomy, and the 5-year survival rate is higher in regions where this proportion is higher.

ABSTRACT: Pancreatic cancer is molecularly diverse, with few effective therapies. Increased mutation burden and defective DNA repair are associated with response to immune checkpoint inhibitors in several other cancer types. We interrogated 385 pancreatic cancer genomes to define hypermutation and its causes. Mutational signatures inferring defects in DNA repair were enriched in those with the highest mutation burdens. Mismatch repair deficiency was identified in 1% of tumors harboring different mechanisms of somatic inactivation of MLH1 and MSH2. Defining mutation load in individual pancreatic cancers and the optimal assay for patient selection may inform clinical trial design for immunotherapy in pancreatic cancer.

ABSTRACT: OBJECTIVES: To develop a composite score for the quality of care for patients with pancreatic cancer in Australia; to determine whether it was affected by patient and health service-related factors; to assess whether the score and survival were correlated. DESIGN, PARTICIPANTS AND SETTING: We reviewed medical records of patients diagnosed with pancreatic cancer during July 2009 - June 2011 and notified to the Queensland and New South Wales cancer registries. DESIGN AND MAIN OUTCOME MEASURES: Participants were allocated proportional quality of care scores based on indicators derived from a Delphi process, ranging from 0 (lowest) to 1 (highest quality care). Associations between patient and health service-related factors and the score were tested by linear regression, and associations between the score and survival with Kaplan-Meier and Cox proportional hazards methods. RESULTS: Proportional quality of care scores were assigned to 1571 patients. Scores for patients living in rural areas were significantly lower than for those in major cities (adjusted difference, 11%; 95% CI, 8-13%); they were higher for patients in the least socio-economically disadvantaged areas (v most disadvantaged areas: 8% higher; 95% CI, 6-11%), who were younger, had better Eastern Cooperative Oncology Group performance status, or who first presented to a hospital with a high pancreatic case volume. Higher scores were associated with improved survival; after adjusting for patient-related factors, each 10 percentage point increase in the score reduced the risk of dying by 6% (hazard ratio, 0.94; 95% CI, 0.91-0.97). CONCLUSION: Geographic category of residence may influence the quality of care received by patients with pancreatic cancer, and survival could be improved if they received optimal care.

ABSTRACT: BACKGROUND: There are indications that pancreatic cancer survival may differ according to sociodemographic factors, such as residential location. This may be due to differential access to curative resection. Understanding factors associated with the decision to offer a resection might enable strategies to increase the proportion of patients undergoing potentially curative surgery. METHODS: Data were extracted from medical records and cancer registries for patients diagnosed with pancreatic cancer between July 2009 and June 2011, living in one of two Australian states. Among patients clinically staged with non-metastatic disease we examined factors associated with survival using Cox proportional hazards models. To investigate survival differences we examined determinants of: 1) attempted surgical resection overall; 2) whether patients with locally advanced disease were classified as having resectable disease; and 3) attempted resection among those considered resectable. RESULTS: Data were collected for 786 eligible patients. Disease was considered locally advanced for 561 (71%) patients, 510 (65%) were classified as having potentially resectable disease and 365 (72%) of these had an attempted resection. Along with age, comorbidities and tumour stage, increasing remoteness of residence was associated with poorer survival. Remoteness of residence and review by a hepatobiliary surgeon were factors influencing the decision to offer surgery. CONCLUSIONS: This study indicated disparity in survival dependent on patients' residential location and access to a specialist hepatobiliary surgeon. Accurate clinical staging is a critical element in assessing surgical resectability and it is therefore crucial that all patients have access to specialised clinical services.

ABSTRACT: BACKGROUND: Patient and health system determinants of outcomes following pancreatic cancer resection, particularly the relative importance of hospital and surgeon volume, are unclear. Our objective was to identify patient, tumour and health service factors related to mortality and survival amongst a cohort of patients who underwent completed resection for pancreatic cancer. METHODS: Eligible patients were diagnosed with pancreatic adenocarcinoma between July 2009 and June 2011 and had a completed resection performed in Queensland or New South Wales, Australia, with either tumour-free (R0) or microscopically involved margins (R1) (n = 270). Associations were examined using logistic regression (for binary outcomes) and Cox proportional hazards or stratified Cox models (for time-to-event outcomes). RESULTS: Patients treated by surgeons who performed <4 resections/year were more likely to die from a surgical complication (versus ≥4 resections/year, P = 0.04), had higher 1-year mortality (P = 0.03), and worse overall survival up to 1.5 years after surgery (adjusted hazard ratio 1.58, 95 % confidence interval 1.07-2.34). Amongst patients who had ≥1 complication within 30 days of surgery, those aged ≥70 years had higher 1-year mortality compared to patients aged <60 years. Adjuvant chemotherapy treatment improved recurrence-free survival (P = 0.01). There were no significant associations between hospital volume and mortality or survival. CONCLUSIONS: Systems should be implemented to ensure that surgeons are completing a sufficient number of resections to optimize patient outcomes. These findings may be particularly relevant for countries with a relatively small and geographically dispersed population.

ABSTRACT: PURPOSE: This study aims to determine if the supportive care needs of people with pancreatic cancer change over time and identify the factors associated with current and future unmet needs. METHODS: Australian pancreatic cancer patients completed a self-administered survey at 0-6 months post-diagnosis (n = 116) then follow-up surveys 2 (n = 82) and 4 months (n = 50) later. The validated survey measured 34 needs across five domains. Weighted generalised estimating equations were used to identify factors associated with having ≥1 current or future moderate-to-high unmet need. RESULTS: The overall proportion of patients reporting ≥1 moderate-or-high-level need did not significantly change over time (baseline = 70 % to 4 months = 75 %), although there was a non-significant reduction in needs for patients who had a complete resection (71 to 63 %) and an increase in patients with locally advanced (73 to 85 %) or metastatic (66 to 88 %) disease. Higher levels of pain (OR 6.1, CI 2.4-15.3), anxiety (OR 3.3, CI 1.5-7.3) and depression (OR 3.2, CI 1.7-6.0) were significantly associated with current needs. People with pain (OR 4.9, CI 1.5-15.4), metastatic disease (OR 2.7, CI 0.7-10.0) or anxiety (OR 2.5, CI 0.7-8.6) had substantially higher odds of reporting needs at their next survey. The prevalence of needs was highest in the physical/daily living and psychological domains (both 53 % at baseline). Pain and anxiety had respectively the strongest associations with these domains. CONCLUSIONS: Careful and continued attention to pain control and psychological morbidity is paramount in addressing significant unmet needs, particularly for people with metastatic disease. Research on how best to coordinate this is crucial.

ABSTRACT: Integrated genomic analysis of 456 pancreatic ductal adenocarcinomas identified 32 recurrently mutated genes that aggregate into 10 pathways: KRAS, TGF-β, WNT, NOTCH, ROBO/SLIT signalling, G1/S transition, SWI-SNF, chromatin modification, DNA repair and RNA processing. Expression analysis defined 4 subtypes: (1) squamous; (2) pancreatic progenitor; (3) immunogenic; and (4) aberrantly differentiated endocrine exocrine (ADEX) that correlate with histopathological characteristics. Squamous tumours are enriched for TP53 and KDM6A mutations, upregulation of the TP63∆N transcriptional network, hypermethylation of pancreatic endodermal cell-fate determining genes and have a poor prognosis. Pancreatic progenitor tumours preferentially express genes involved in early pancreatic development (FOXA2/3, PDX1 and MNX1). ADEX tumours displayed upregulation of genes that regulate networks involved in KRAS activation, exocrine (NR5A2 and RBPJL), and endocrine differentiation (NEUROD1 and NKX2-2). Immunogenic tumours contained upregulated immune networks including pathways involved in acquired immune suppression. These data infer differences in the molecular evolution of pancreatic cancer subtypes and identify opportunities for therapeutic development.

ABSTRACT: AIM: Overall 5-year survival for pancreatic cancer is ∼5%. Optimizing the care that pancreatic cancer patients receive may be one way of improving outcomes. The objective of this study was to establish components of care which Australian health professionals believe important to optimally manage patients with pancreatic cancer. METHODS: Using a Delphi process, a multidisciplinary panel of 250 health professionals were invited to provide a list of factors they considered important for optimal care of pancreatic cancer patients. They were then asked to score and then rescore (from one [no importance/disagree] to 10 [very important/agree]) the factors. The mean and coefficient of variation scores were calculated and categorized into three levels of importance. RESULTS: Overall, 63 (66% of those sent the final questionnaire; 25% of those initially invited) health professionals from nine disciplines completed the final scoring of 55 statements/factors encompassing themes of presentation/staging, surgery and biliary obstruction, multidisciplinary team details and oncology. Mean scores ranged from 3.7 to 9.7 with the highest related to communication and patient assessment. There was substantial intra- and interdisciplinary variation in views about MDT membership and roles. CONCLUSION: Overall, the opinions of Australian health professionals reflect international guideline recommended care; however, they identified a number of additional factors focusing on where patients should be treated, the importance of clear communication and the need for multidisciplinary care which were not included in current clinical practice guidelines. Differences in priorities between specialty groups were also identified.

ABSTRACT: OBJECTIVE: People diagnosed with pancreatic cancer have the worst survival prognosis of any cancer. No previous research has documented the supportive care needs of this population. Our objective was to describe people's needs and use of support services and to examine whether these differed according to whether or not patients had undergone surgical resection. METHODS: Queensland pancreatic or ampullary cancer patients (n = 136, 54% of those eligible) completed a survey, which assessed 34 needs across five domains (Supportive Care Needs Survey-Short Form) and use of health services. Differences by resection were compared with Chi-squared tests. RESULTS: Overall, 96% of participants reported having some needs. More than half reported moderate-to-high unmet physical (54%) or psychological (52%) needs, whereas health system/information (32%), patient care (21%) and sexuality needs (16%) were described less frequently. The three most frequently reported moderate-to-high needs included 'not being able to do things they used to do' (41%), 'concerns about the worries of those close' (37%) and 'uncertainty about the future' (30%). Patients with non-resectable disease reported greater individual information needs, but their needs were otherwise similar to patients with resectable disease. Self-reported use of support was low; only 35% accessed information, 28%, 18% and 15% consulted a dietician, complementary medicine practitioner or mental health practitioner, respectively. Palliative care access was greater (59% vs 27%) among those with non-resectable disease. CONCLUSION: Very high levels of needs were reported by people with pancreatic or ampullary cancer. Future work needs to elucidate why uptake of appropriate supportive care is low and which services are required.

ABSTRACT: OBJECTIVES: Despite pancreatic cancer being the fifth highest cause of cancer death in developed regions, there is a paucity of population-based management details for patients with pancreatic cancer. The objective of this study was to reflect on current practice and outcomes to facilitate future improvement. METHODS: A comprehensive population-based patterns-of-care study in 2 Australian states was conducted. Patients diagnosed with pancreatic adenocarcinoma between July 2009 and June 2011 were identified by cancer registries, and detailed clinical data were collected from medical records. RESULTS: Data were collected for 1863 patients, 96% of those eligible. The majority resided in major cities; their median age was 72 years, and 54% were men. Over half of the cases (58%) had metastatic disease at diagnosis. Resection was attempted for 20% of patients but only completed in 15%. The uptake of adjuvant chemotherapy (76%) and the proportion alive at 1-year (22%) were higher than reported in previous population-based reports. Of those with no complete surgical resection, 43% received palliative chemotherapy. CONCLUSIONS: This population-based overview of the management of patients with pancreatic cancer suggests that, despite evidence that the proportion surviving and the use of adjuvant chemotherapy has increased, there may still be underutilization of cancer-directed therapies.

ABSTRACT: Pancreatic cancer remains one of the most lethal of malignancies and a major health burden. We performed whole-genome sequencing and copy number variation (CNV) analysis of 100 pancreatic ductal adenocarcinomas (PDACs). Chromosomal rearrangements leading to gene disruption were prevalent, affecting genes known to be important in pancreatic cancer (TP53, SMAD4, CDKN2A, ARID1A and ROBO2) and new candidate drivers of pancreatic carcinogenesis (KDM6A and PREX2). Patterns of structural variation (variation in chromosomal structure) classified PDACs into 4 subtypes with potential clinical utility: the subtypes were termed stable, locally rearranged, scattered and unstable. A significant proportion harboured focal amplifications, many of which contained druggable oncogenes (ERBB2, MET, FGFR1, CDK6, PIK3R3 and PIK3CA), but at low individual patient prevalence. Genomic instability co-segregated with inactivation of DNA maintenance genes (BRCA1, BRCA2 or PALB2) and a mutational signature of DNA damage repair deficiency. Of 8 patients who received platinum therapy, 4 of 5 individuals with these measures of defective DNA maintenance responded.

ABSTRACT: Pancreatic cancer is a highly lethal malignancy with few effective therapies. We performed exome sequencing and copy number analysis to define genomic aberrations in a prospectively accrued clinical cohort (n = 142) of early (stage I and II) sporadic pancreatic ductal adenocarcinoma. Detailed analysis of 99 informative tumours identified substantial heterogeneity with 2,016 non-silent mutations and 1,628 copy-number variations. We define 16 significantly mutated genes, reaffirming known mutations (KRAS, TP53, CDKN2A, SMAD4, MLL3, TGFBR2, ARID1A and SF3B1), and uncover novel mutated genes including additional genes involved in chromatin modification (EPC1 and ARID2), DNA damage repair (ATM) and other mechanisms (ZIM2, MAP2K4, NALCN, SLC16A4 and MAGEA6). Integrative analysis with in vitro functional data and animal models provided supportive evidence for potential roles for these genetic aberrations in carcinogenesis. Pathway-based analysis of recurrently mutated genes recapitulated clustering in core signalling pathways in pancreatic ductal adenocarcinoma, and identified new mutated genes in each pathway. We also identified frequent and diverse somatic aberrations in genes described traditionally as embryonic regulators of axon guidance, particularly SLIT/ROBO signalling, which was also evident in murine Sleeping Beauty transposon-mediated somatic mutagenesis models of pancreatic cancer, providing further supportive evidence for the potential involvement of axon guidance genes in pancreatic carcinogenesis.

ABSTRACT: BACKGROUND: Current staging methods for pancreatic cancer (PC) are inadequate, and biomarkers to aid clinical decision making are lacking. Despite the availability of the serum marker carbohydrate antigen 19.9 (CA19.9) for over two decades, its precise role in the management of PC is yet to be defined, and as a consequence, it is not widely used. METHODS: We assessed the relationship between perioperative serum CA19.9 levels, survival and adjuvant chemotherapeutic responsiveness in a cohort of 260 patients who underwent operative resection for PC. RESULTS: By specifically assessing the subgroup of patients with detectable CA19.9, we identified potential utility at key clinical decision points. Low postoperative CA19.9 at 3 months (median survival 25.6 vs 14.8 months, P=0.0052) and before adjuvant chemotherapy were independent prognostic factors. Patients with postoperative CA 19.9 levels>90 U/ml did not benefit from adjuvant chemotherapy (P=0.7194) compared with those with a CA19.9 of ≤90 U/ml (median 26.0 vs 16.7 months, P=0.0108). Normalization of CA19.9 within 6 months of resection was also an independent favorable prognostic factor (median 29.9 vs 14.8 months, P=0.0004) and normal perioperative CA19.9 levels identified a good prognostic group, which was associated with a 5-year survival of 42%. CONCLUSIONS: Perioperative serum CA19.9 measurements are informative in patients with detectable CA19.9 (defined by serum levels of >5 U/ml) and have potential clinical utility in predicting outcome and response to adjuvant chemotherapy. Future clinical trials should prioritize incorporation of CA19.9 measurement at key decision points to prospectively validate these findings and facilitate implementation.

ABSTRACT: BACKGROUND AND AIM: Clinicopathological data regarding pancreatic solid pseudopapillary tumors (SPT) in a multiethnic country are limited. The aim of the present study was to characterize pancreatic SPT in Australia. METHODS: Clinicopathological features, treatment, immunohistochemical findings and outcome data of 34 patients (79% Caucasian, 12% Asian, 6% South Pacific Islander and 3% African) with pancreatic SPT were reviewed. RESULTS: The most presenting complaint was abdominal pain. Median diameter of tumors was 60 mm (range: 20-220); predominantly located in the pancreatic tail (tail : body : head = 23:3:8). All tumors were resected and patients underwent surgery, including a liver resection for metastasis, all patients were alive after a median follow up of 70 months (IQR: 48-178). Two patients underwent repeated surgery for local recurrences with liver metastases after 8 and 18 months, which were successfully managed by surgical resection. Completeness of excision, perineural spread, vascular space invasion, mitotic rate and cellular atypia did not predict recurrence. In all cases, there was aberrant nuclear staining of beta-catenin and a loss of membranous expression of E-cadherin with aberrant nuclear localization of the cytoplasmic domain. Most pancreatic SPT were also strongly positive for CD10 (96%), progesterone receptor (79%), cytokeratin (28%), synapthophysin (26%) and chromogranin (15%). CONCLUSIONS: Pancreatic SPT occur in all races and are uniformly indolent. Given complete resection of a pancreatic SPT is usually curative and recurrences can be treated with re-operation, correct diagnosis is important.

ABSTRACT: PURPOSE: Current adjuvant therapies for pancreatic cancer (PC) are inconsistently used and only modestly effective. Because a high proportion of patients who undergo resection for PC likely harbor occult metastatic disease, any adjuvant trials assessing therapies such as radiotherapy directed at locoregional disease are significantly underpowered. Stratification based on the probability (and volume) of residual locoregional disease could play an important role in the design of future clinical trials assessing adjuvant radiotherapy. PATIENTS AND METHODS: We assessed the relationships between margin involvement, the proximity to operative resection margins and outcome in a cohort of 365 patients who underwent operative resection for PC. RESULTS: Microscopic involvement of a resection margin by tumor was associated with a poor prognosis. Stratifying the minimum clearance of resection margins by 0.5-mm increments demonstrated that although median survival was no different to clear margins based on these definitions, it was not until the resection margin was clear by more than 1.5 mm that optimal long-term survival was achieved. CONCLUSION: These data demonstrate that a margin clearance of more than 1.5 mm is important for long-term survival in a subgroup of patients. More aggressive therapeutic approaches that target locoregional disease such as radiotherapy may be beneficial in patients with close surgical margins. Stratification of patients for entry onto future clinical trials based on this criterion may identify those patients who benefit from adjuvant radiotherapy.

ABSTRACT: BACKGROUND & AIMS: Current methods of preoperative staging and predicting outcome following pancreatectomy for pancreatic cancer (PC) are inadequate. We evaluated the utility of multiple biomarkers from distinct biologic pathways as potential predictive markers of response to pancreatectomy and patient survival. METHODS: We assessed the relationship of candidate biomarkers known, or suspected, to be aberrantly expressed in PC, with disease-specific survival and response to therapy in a cohort of 601 patients. RESULTS: Of the 17 candidate biomarkers examined, only elevated expression of S100A2 was an independent predictor of survival in both the training (n = 162) and validation sets (n = 439; hazard ratio [HR], 2.19; 95% confidence interval [CI]: 1.48-3.25; P < .0001) when assessed in a multivariate model with clinical variables. Patients with high S100A2 expressing tumors had no survival benefit with pancreatectomy compared with those with locally advanced disease, whereas those without high S100A2 expression had a survival advantage of 10.6 months (19.4 vs 8.8 months, respectively) and a HR of 3.23 (95% CI: 2.39-4.33; P < .0001). Of significance, patients with S100A2-negative tumors had a significant survival benefit from pancreatectomy even in the presence of involved surgical margins (median, 15.7 months; P = .0007) or lymph node metastases (median, 17.4 months; P = .0002). CONCLUSIONS: S100A2 expression is a good predictor of response to pancreatectomy for PC and suggests that high S100A2 expression may be a marker of a metastatic phenotype. Prospective measurement of S100A2 expression in diagnostic biopsy samples has potential clinical utility as a predictive marker of response to pancreatectomy and other therapies that target locoregional disease.
