Repeated participation in pancreatic cancer surveillance by high-risk individuals imposes low psychological burden

The role of endoscopic ultrasound in the detection of pancreatic lesions in high-risk individuals

Individuals at high risk of developing pancreatic ductal adenocarcinoma are eligible for surveillance within research programs. These programs employ periodic imaging in the form of magnetic resonance imaging/magnetic resonance cholangiopancreatography or endoscopic ultrasound for the detection of early cancer or high-grade precursor lesions. This narrative review discusses the role of endoscopic ultrasound within these surveillance programs. It details its overall strengths and limitations, yield, burden on patients, and how it compares to magnetic resonance imaging. Finally, recommendations are given when and how to incorporate endoscopic ultrasound in the surveillance of high-risk individuals.

The Experience of Uncertainty in Individuals With High Risk for Pancreatic Cancer

BACKGROUND

Individuals with a strong family history of pancreatic cancer or a known hereditary cancer syndrome that is associated with pancreatic cancer are considered at high risk for developing pancreatic cancer. Living with a high risk for often fatal cancer is accompanied by high levels of uncertainty. Uncertainty is also independently associated with negative health outcomes. By understanding issues, sources, and responses to uncertainty, targeted supportive care strategies can be provided.

OBJECTIVES

This study aimed to examine how uncertainty manifests in the experience of being at high risk to develop pancreatic cancer and to describe issues, sources of, and responses to uncertainty.

METHODS

In this secondary qualitative descriptive study, we analyzed 19 interviews with persons living with inherited pancreatic cancer risk. Analysis was guided by a conceptual framework of uncertainty and responses to uncertainty.

RESULTS

Participants described multiple personal, practical, and scientific issues of uncertainty, centering on what to expect for their future health. Participants also expressed positive and negative cognitive, emotional, and behavioral responses to uncertainty, including engaging in surveillance. Uncertainty sources were both individual experiences as well as perceptions of healthcare provider uncertainty with managing pancreatic cancer risk.

CONCLUSION

Pancreatic cancer risk includes issues of uncertainty related to personal mortality, defining and managing risk, and experiencing surveillance. Positive and negative responses to this uncertainty could be targeted through interventions.

IMPLICATION FOR PRACTICE

The oncology nurse should assess for sources of and responses to uncertainty in persons at risk for pancreatic cancer and offer psychosocial and educational support.

Assessment of the Psychosocial Impact of Pancreatic Cancer Surveillance in High-Risk Individuals

OBJECTIVES

Pancreatic cancer (PC) surveillance of high-risk individuals (HRIs) downstages PC and improves survival. However, it remains less clear whether PC surveillance has a positive psychosocial impact on HRIs. Herein, we aimed to define the attitudes and beliefs of HRIs undergoing PC surveillance, and the immediate and sustained psychosocial impact of PC surveillance in HRIs.

METHODS

100 HRIs undergoing PC surveillance by endoscopic ultrasound (EUS) completed three surveys addressing different components of the psychosocial impact of PC surveillance. Logistic regression analyses were performed to identify predictive factors relating to these components.

RESULTS

Most HRIs reported increased perceived benefits of PC surveillance, self-efficacy, and perceived severity of PC. HRIs reported few negative emotions prior to surveillance and frequent positive emotions after surveillance. Compared to prior to surveillance, there was a 53.5% decrease in the level of distress reported by HRIs after surveillance, which was sustained for 4-6 weeks post-surveillance. Family history of PC and lower self-reported mental health were identified as predictors for increased perceived susceptibility to PC (p < 0.01) and greater change in distress pre- to post-surveillance (p < 0.01), respectively.

CONCLUSIONS

Our findings suggest that PC surveillance can lead to sustained psychosocial benefits in HRIs.

Familial Pancreatic Cancer

Individuals at increased risk of developing pancreatic cancer, including those with a significant family history of the disease and those with pancreatic cancer susceptibility gene variants, can benefit from pancreas surveillance. Most pancreatic cancers diagnosed during surveillance are early-stage and such patients can achieve long-term survival. Determining who should undergo pancreas surveillance is still a work-in-progress, but the main tools clinicians use to estimate an individual's risk of pancreatic cancer are patient's age, the extent of their family history of pancreatic cancer, and whether or not they have a pancreatic cancer susceptibility gene mutation.

Current Screening Strategies for Pancreatic Cancer

Pancreatic ductal adenocarcinoma (PDAC) is a dreaded malignancy with a dismal 5-year survival rate despite maximal efforts on optimizing treatment strategies. Radical surgery is the only potential curative procedure. Unfortunately, the majority of patients are diagnosed with locally advanced or metastatic disease, which renders them ineligible for curative resection. Early detection of PDAC is thus considered to be the most effective way to improve survival. In this regard, pancreatic screening has been proposed to improve results by detecting asymptomatic stages of PDAC and its precursors. There is now evidence of benefits of systematic surveillance in high-risk individuals, and the current guidelines emphasize the potential of screening to affect overall survival in individuals with genetic susceptibility syndromes or familial occurrence of PDAC. Here we aim to summarize the current knowledge about screening strategies for PDAC, including the latest epidemiological data, risk factors, associated hereditary syndromes, available screening modalities, benefits, limitations, as well as management implications.

Hereditary pancreatic cancer

Pancreatic cancer is one of the deadliest malignancies. Therefore, there is an urgent need to detect pancreatic cancer in an earlier stage to improve outcomes. A variety of hereditary cancer syndromes have been associated with an increased risk of developing pancreatic cancer, and these individuals may benefit from surveillance programs. Surveillance programs have shown potential to improve outcomes, but have important risks such as overtreatment. In this review we will discuss the definitions and epidemiology of hereditary pancreatic cancer, recommendations for genetic testing and participation in surveillance. Important aspects are differences in surveillance strategies, target lesions, and potential benefits and harms of surveillance. Lastly we will highlight future directions for research and improvement of care for individuals at high-risk of pancreatic cancer.

Clinical Data Prediction Model to Identify Patients With Early-Stage Pancreatic Cancer

PURPOSE

Pancreatic cancer is an aggressive malignancy with patients often experiencing nonspecific symptoms before diagnosis. This study evaluates a machine learning approach to help identify patients with early-stage pancreatic cancer from clinical data within electronic health records (EHRs).

MATERIALS AND METHODS

From the Optum deidentified EHR data set, we identified early-stage (n = 3,322) and late-stage (n = 25,908) pancreatic cancer cases over 40 years of age diagnosed between 2009 and 2017. Patients with early-stage pancreatic cancer were matched to noncancer controls (1:16 match). We constructed a prediction model using eXtreme Gradient Boosting (XGBoost) to identify early-stage patients on the basis of 18,220 features within the EHR including diagnoses, procedures, information within clinical notes, and medications. Model accuracy was assessed with sensitivity, specificity, positive predictive value, and the area under the curve.

RESULTS

The final predictive model included 582 predictive features from the EHR, including 248 (42.5%) physician note elements, 146 (25.0%) procedure codes, 91 (15.6%) diagnosis codes, 89 (15.3%) medications, and 9 (1.5%) demographic features. The final model area under the curve was 0.84. Choosing a model cut point with a sensitivity of 60% and specificity of 90% would enable early detection of 58% late-stage patients with a median of 24 months before their actual diagnosis.

CONCLUSION

Prediction models using EHR data show promise in the early detection of pancreatic cancer. Although widespread use of this approach on an unselected population would produce high rates of false-positive tests, this technique may be rapidly impactful if deployed among high-risk patients or paired with other imaging or biomarker screening tools.

The psychological impact and experience of breast cancer screening in young women with an increased risk of breast cancer due to neurofibromatosis type 1

Women with neurofibromatosis type 1 (NF1) have an increased risk of developing early breast cancer with a poorer prognosis compared to the general population. Therefore, international management guidelines recommend regular screening in women with NF1 starting from 30 to 35 years. As the psychological impacts of breast cancer screening in other high-risk populations cannot be extended to women with NF1, due to increased incidence of cognitive and mental health issues, the psychological harms of breast screening in women with NF1 are unknown. Consequently, the aim of this study was to assess the psychological impact of breast cancer screening in women with NF1 attending an established risk management clinic. Twenty-eight women with NF1 (30–50 years) completed psychological well-being and patient experience questionnaires, administered across five time points, before and after their initial and second round annual breast screening visits. Preliminary findings demonstrated the screening regimen was well-tolerated, with most participants reporting high satisfaction with the screening process. Overall, no significant increase in psychological distress related to the breast screening process was identified, with mean cancer worry and anxiety scores decreasing over time. However, some women did experience negative aspects of screening and barriers to re-attendance at annual breast screening appointments. As some women with NF1 exhibited clinical levels of psychological distress prior to screening, efforts to identify those at risk and additional support to address concerns and expectations throughout the breast screening process may be beneficial.

Identifying key factors for the effectiveness of pancreatic cancer screening: A model-based analysis

Pancreatic cancer (PC) survival is poor, as detection usually occurs late, when treatment options are limited. Screening of high‐risk individuals may enable early detection and a more favorable prognosis. Knowledge gaps prohibit establishing the effectiveness of screening. We developed a Microsimulation Screening Analysis model to analyze the impact of relevant uncertainties on the effect of PC screening in high‐risk individuals. The model simulates two base cases: one in which lesions always progress to PC and one in which indolent and faster progressive lesions coexist. For each base case, the effect of annual and 5‐yearly screening with endoscopic ultrasonography/magnetic resonance imaging was evaluated. The impact of variance in PC risk, screening test characteristics and surgery‐related mortality was evaluated using sensitivity analyses. Screening resulted in a reduction of PC mortality by at least 16% in all simulated scenarios. This reduction depended strongly on the natural disease course (annual screening: −57% for “Progressive‐only” vs −41% for “Indolent Included”). The number of screen and surveillance tests needed to prevent one cancer death was impacted most by PC risk. A 10% increase in test sensitivity reduced mortality by 1.9% at most. Test specificity is important for the number of surveillance tests. In conclusion, screening reduces PC mortality in all modeled scenarios. The natural disease course and PC risk strongly determines the effectiveness of screening. Test sensitivity seems of lesser influence than specificity. Future research should gain more insight in PC pathobiology to establish the true value of PC screening in high‐risk individuals.

What's new?

About 10 percent of pancreatic cancers occur in individuals with inherited risk factors. While screening such high‐risk individuals can facilitate the detection of precursor lesions and early‐stage cancer, the extent to which benefits outweigh harms, including overdiagnosis, remains unknown. Here, using a microsimulation model, the authors explored uncertainties concerning the early detection of pancreatic cancer and analyzed the impact of these uncertainties on the effect of screening. In all simulated scenarios, screening was associated with reduced pancreatic cancer mortality. The effectiveness of screening was most strongly impacted by characteristics of natural disease course and level of pancreatic cancer risk

Long-term positive psychological outcomes in an Australian pancreatic cancer screening program

Screening for pancreatic cancer (PC) in high-risk groups aimed to detect early cancers is currently done only in the research setting, and data on psychological outcomes of screening in these populations is scarce. To determine the psychological impact of a national Australian pancreatic screening program, a prospective study was conducted using validated psychological measures: impact of events scale (IES), psychological consequences questionnaire (PCQ) and the cancer worry scale. Measures were administered at baseline, 1-month and at 1-year post-enrolment and correlations with abnormal endoscopic ultrasound (EUS) results were calculated. Over a 6-year period, 102 participants were recruited to the screening program. Thirty-nine patients (38.2%) had an abnormal endoscopic ultrasound, and two patients (2.0%) were diagnosed with PC and two with other malignancies. Those with a personal history of cancer or a positive BRCA2 mutation demonstrated significantly increased worry about developing other types of cancer at baseline (p < 0.01). Irrespective of EUS result, there was a significant decrease of total IES score at 1 year (Z = - 2.0, p = 0.041). In patients with abnormal EUS results, there was a decrease in the total IES score at 1 year (Z = - 2.5, p = 0.011). In participants deemed to be most distressed at baseline based on their negative PCQ score, there was a significant decrease of the total PCQ (Z = - 3.2, p = 0.001), emotional (Z = - 3.0, p = 0.001), social (Z = 3.0, p = 0.001) and physical (Z = - 2.8, p = 0.002) subscale at 1-year post-intervention. This study provides evidence of the long-term psychological benefits of PC screening in high-risk patients. There was no negative impact of screening in the short-term and the positive benefits appeared at 1-year post-intervention irrespective of screening result.

BRCA in Gastrointestinal Cancers: Current Treatments and Future Perspectives

A strong association between pancreatic cancer and BRCA1 and BRCA2 mutations is documented. Based on promising results of breast and ovarian cancers, several clinical trials with poly (ADP-ribose) polymerase inhibitors (PARPi) are ongoing for gastrointestinal (GI) malignancies, especially for pancreatic cancer. Indeed, the POLO trial results provide promising and awaited changes for the pancreatic cancer therapeutic landscape. Contrariwise, for other gastrointestinal tumors, the rationale is currently only alleged. The role of BRCA mutation in gastrointestinal cancers is the subject of this review. In particular, we aim to provide the latest updates about novel therapeutic strategies that, exploiting DNA repair defects, promise to shape the future therapeutic scenario of GI cancers.

AGA Clinical Practice Update on Pancreas Cancer Screening in High-Risk Individuals: Expert Review

DESCRIPTION

The purpose of this American Gastroenterological Association Institute Clinical Practice Update is to describe the indications for screening for pancreas cancer in high-risk individuals.

METHODS

The evidence reviewed in this work is based on reports of pancreas cancer screening studies in high-risk individuals and expert opinion. BEST PRACTICE ADVICE 1: Pancreas cancer screening should be considered in patients determined to be at high risk, including first-degree relatives of patients with pancreas cancer with at least 2 affected genetically related relatives. BEST PRACTICE ADVICE 2: Pancreas cancer screening should be considered in patients with genetic syndromes associated with an increased risk of pancreas cancer, including all patients with Peutz-Jeghers syndrome, hereditary pancreatitis, patients with CDKN2A gene mutation, and patients with 1 or more first-degree relatives with pancreas cancer with Lynch syndrome, and mutations in BRCA1, BRCA2, PALB2, and ATM genes. BEST PRACTICE ADVICE 3: Genetic testing and counseling should be considered for familial pancreas cancer relatives who are eligible for surveillance. A positive germline mutation is associated with an increased risk of neoplastic progression and may also lead to screening for other relevant associated cancers. BEST PRACTICE ADVICE 4: Participation in a registry or referral to a pancreas Center of Excellence should be pursued when possible for high-risk patients undergoing pancreas cancer screening. BEST PRACTICE ADVICE 5: Clinicians should not screen average-risk individuals for pancreas cancer. BEST PRACTICE ADVICE 6: Pancreas cancer screening in high-risk individuals should begin at age 50 years, or 10 years younger than the initial age of familial onset. Screening should be initiated at age 40 years in CKDN2A and PRSS1 mutation carriers with hereditary pancreatitis and at age 35 years in the setting of Peutz-Jeghers syndrome. BEST PRACTICE ADVICE 7: Magnetic resonance imaging and endoscopic ultrasonography (EUS) should be used in combination as the preferred screening modalities in individuals undergoing pancreas cancer screening. BEST PRACTICE ADVICE 8: The target detectable pancreatic neoplasms are resectable stage I pancreatic ductal adenocarcinoma and high-risk precursor neoplasms, such as intraductal papillary mucinous neoplasms with high-grade dysplasia and some enlarged pancreatic intraepithelial neoplasias. BEST PRACTICE ADVICE 9: Screening intervals of 12 months should be considered when there are no concerning pancreas lesions, with shortened intervals and/or the performance of EUS in 6-12 months directed towards lesions determined to be low risk (by a multidisciplinary team). EUS evaluation should be performed within 3-6 months for indeterminate lesions and within 3 months for high-risk lesions, if surgical resection is not planned. New-onset diabetes in a high-risk individual should lead to additional diagnostic studies or change in surveillance interval. BEST PRACTICE ADVICE 10: Decisions regarding therapy directed towards abnormal findings detected during screening should be made by a dedicated multidisciplinary team together with the high-risk individual and their family. BEST PRACTICE ADVICE 11: Surgical resection should be performed at high-volume centers. BEST PRACTICE ADVICE 12: Clinicians should consider discontinuing pancreas cancer screening in high-risk individuals when they are more likely to die of non-pancreas cancer-related causes due to comorbidity and/or are not candidates for pancreas resection. BEST PRACTICE ADVICE 13: The limitations and potential risks of pancreas cancer screening should be discussed with patients before initiating a screening program.

The emotional impact of surveillance programs for pancreatic cancer on high-risk individuals: A prospective analysis

OBJECTIVE

Literature shows that emotional status can influence participation in screening/surveillance programs, and that screening/surveillance programs may alter the psychological well-being of subjects examined. This study aims to assess if participating in a surveillance program for pancreatic cancer early detection is associated with abnormal levels of psychological distress in high-risk individuals (HRIs), compared to the general population.

METHODS

Fifty-four HRIs participating in a magnetic resonance cholangiopancreatography (MRCP)-based surveillance program completed several psychological assessment questionnaires, investigating global functioning, self-efficacy, perceived stress, coping abilities, and social support. The questionnaires were administered by a clinical psychologist after the MRCP but before the subjects were informed about the results of the scans. The HRIs were subjects with strong familiarity of pancreatic cancer and/or carriers of known genetic mutations related to cancer susceptibility. The psychological assessment was made at the time of the first examination.

RESULTS

The population was characterized by an overall good psychological status. Scoring of our sample was comparable to the general population norms. The HRIs showed decent global functioning, high self-efficacy levels, low perceived stress in the last month prior to examination, efficient emotion-focused coping strategies, and an adequate social support system. The younger subjects' subpopulation only revealed higher levels of stress.

CONCLUSIONS

From a psychological point of view, an MRCP-based pancreatic cancer annual surveillance seemed not to influence the HRIs' psychological well-being, unless in young people. Further studies are needed to better establish if there are any changes in distress levels over time and how emotional status influences participation in surveillance programs.

Patient-reported burden of intensified surveillance and surgery in high-risk individuals under pancreatic cancer surveillance

In high-risk individuals participating in a pancreatic cancer surveillance program, worrisome features warrant for intensified surveillance or, occasionally, surgery. Our objectives were to determine the patient-reported burden of intensified surveillance and/or surgery, and to assess post-operative quality of life and opinion of surgery. Participants in our pancreatic cancer surveillance program completed questionnaires including the Cancer Worry Scale (CWS) and the Hospital Anxiety and Depression Scale (HADS). For individuals who underwent intensified surveillance, questionnaires before, during, and ≥ 3 weeks after were analyzed. In addition, subjects who underwent intensified surveillance in the past 3 years or underwent surgery at any time, were invited for an interview, that included the Short-Form 12 (SF-12). A total of 31 high-risk individuals were studied. During the intensified surveillance period, median CWS scores were higher (14, IQR 7), as compared to before (12, IQR 9, P = 0.007) and after (11, IQR 7, P = 0.014), but eventually returned back to baseline (P = 0.823). Median HADS scores were low: 5 (IQR 6) for anxiety and 3 (IQR 5) for depression, and they were unaffected by the intensified surveillance period. Of the 10 operated patients, 1 (10%) developed diabetes and 7 (70%) pancreatic exocrine insufficiency. The interviews yielded median quality-of-life scores comparable to the general population. Also, after surgery, patients’ attitudes towards surveillance were unchanged (5/10, 50%) or became more positive (4/10, 40%). Although patients were aware of the (sometimes benign) pathological outcome, when asked if surgery had been justified, only 20% (2/10) disagreed, and all would again have chosen to undergo surgery. In conclusion, in individuals at high risk for pancreatic cancer, intensified surveillance temporarily increased cancer worries, without affecting general anxiety or depression. Although pancreatic surgery led to substantial co-morbidity, quality of life was similar to the general population, and surgery did not negatively affect the attitude towards surveillance.

Quality of life impact of EUS in patients at risk for developing pancreatic cancer

Background and Objectives

The current knowledge about the psychological impact of pancreatic cancer (PC) screening is limited. We aimed to assess the changes in quality of life (QOL) and level of distress after undergoing EUS in individuals with pancreatic cystic lesions (PCLs) and in patients at high risk for PC based on genetic and familial factors.

Methods

Eighty patients with PCL and/or increased genetic or familial risk for PC who had undergone EUS were contacted. Fifty percent of those patients successfully completed the brief profile of mood states (POMS) and the linear analog scale assessment (LASA) QOL questionnaires to evaluate their pre/post-EUS overall QOL. The effect size (ES) method was used to assess clinically meaningful changes in the scores.

Results

There was a significant difference in patients' overall QOL scores before and after the EUS procedure (LASA, mean difference 0.73, standard deviation (SD) 1.76, ES 0.58, P < 0.01; brief POMS, mean difference -5.46, SD -6.72, ES 0.81, P < 0.01).

Conclusions

QOL of patients with PCL or increased risk factors for PC is significantly improved after a EUS/EUS-guided fine-needle aspiration (FNA) negative for malignancy.

Pancreatic cyst surveillance imposes low psychological burden

BACKGROUND/OBJECTIVES

For the currently recommended pancreatic cyst surveillance to be feasible, participant adherence is a prerequisite. Our objective was to evaluate the psychological burden of pancreatic cyst surveillance from a participant's perspective.

METHODS

The present participant survey is part of an international cohort study (PACYFIC study, www.pacyfic.net), which prospectively records the outcome of surveillance of asymptomatic pancreatic cysts. Participants are invited to complete questionnaires before and during cyst surveillance.

RESULTS

109 participants, 31 enrolled before and 78 during surveillance (median time since cyst diagnosis 16.5 (IQR 36) months), returned a total of 179 questionnaires. The majority indicated that surveillance reduces concerns of developing pancreatic cancer (82%), gives a sense of certainty (81%) and is a good method to detect cancer (91%). Participants already undergoing surveillance reported more negative aspects than those still to commence, like sleeping worse (30% vs 13%, P = 0.035), postponing plans (32% vs 13%, P = 0.031), and finding the follow-up burdensome (33% vs 13%, P = 0.044). Overall, the vast majority (94%) deemed advantages to outweigh disadvantages. Anxiety and depression scores were low (median Hospital Anxiety and Depression Scale 4 for anxiety (IQR 6), 2 for depression (IQR 5)).

CONCLUSION

The psychological burden of pancreatic cyst surveillance is low. Therefore, participant adherence is expected to be high and annual surveillance seems feasible.

Genetic counselling and personalised risk assessment in the Australian pancreatic cancer screening program

Background

Pancreatic cancer (PC) is an aggressive disease with a dismal 5-year survival rate. Surveillance of high-risk individuals is hoped to improve survival outcomes by detection of precursor lesions or early-stage malignancy.

Methods

Since 2011, a national high-risk cohort recruited through St Vincent’s Hospital, Sydney, has undergone prospective PC screening incorporating annual endoscopic ultrasound, formal genetic counselling and mutation analysis as appropriate. PancPRO, a Bayesian PC risk assessment model, was used to estimate 5-year and lifetime PC risks for familial pancreatic cancer (FPC) participants and this was compared to their perceived chance of pancreatic and other cancers. Genetic counselling guidelines were developed to improve consistency. Follow-up questionnaires were used to assess the role of genetic counselling and testing.

Results

We describe the Australian PC screening program design and recruitment strategy and the results of the first 102 individuals who have completed at least one-year of follow-up. Seventy-nine participants met the FPC criteria (≥ two first-degree relatives affected), 22 individuals had both a BRCA2 pathogenic variant and a close relative with PC and one had a clinical diagnosis of Peutz-Jeghers syndrome. Participants reported a high perceived chance of developing PC regardless of their genetic testing status. PancPRO reported FPC participants’ mean 5-year and lifetime PC risks as 1.81% (range 0.2–3.2%) and 10.17% (range 2.4–14.4%), respectively. Participants’ perceived PC chance did not correlate with their PancPRO 5-year (r = − 0.17, p = 0.128) and lifetime PC risks (r = 0.19, p = 0.091). Two-thirds felt that current genetic testing would help them, and 91% of tested participants were glad to have undergone genetic testing. Overall, 79% of participants found genetic counselling to be helpful, and 88% reported they would recommend counselling to their relatives.

Conclusions

Participants reported multiple benefits of genetic counselling and testing but continue to seek greater clarification about their individual PC risk. Extension of PancPRO is required to enable personalised PC risk assessment for all high-risk sub-groups. More detailed discussion of PC risk for BRCA2 pathogenic variant carriers, providing a written summary in all cases and a plan for genetics review were identified as areas for improvement.

Health behaviours and beliefs in individuals with familial pancreatic cancer

Individuals at high risk for pancreatic cancer are recommended surveillance and healthy lifestyle behaviours and patient experience with recommendations are understudied. To describe engagement and experience with surveillance, tobacco and alcohol use, health beliefs and motivation (Champion Health Belief Measure) and the relationship with personal, psychosocial (Impact of Event Scale), and familial characteristics. Interest in integrative therapies (complementary therapies) are described. A multi-site cross-sectional survey including individuals at high risk for pancreatic cancer with no diagnosis of pancreatic cancer who have been evaluated at a comprehensive cancer center. Descriptive statistics and Wilcoxon rank sum test and Fisher's exact test were used to assess univariate associations. Of the 132 respondents (72% response rate), 92 (70%) reported undergoing surveillance which was associated with older age (p = 0.001). Of which, 36% and 51% report that magnetic resonance imaging (MRI) or endoscopic ultrasound (EUS), respectively, were uncomfortable; 22% and 30% dread the next MRI or EUS, respectively. Of those who reported alcohol consumption (n = 88); 15% consumed 1 or more drinks daily and no alcohol consumption was associated with higher Impact of Event scale scores (p = 0.024). A total of six participants were currently smoking every day or some days. Participants reported high motivation to engage in heathy behaviours and 92% were interested in integrative therapies. In these select participants, most were engaging in pancreatic cancer surveillance, alcohol intake was moderate, and tobacco intake was minimal. Modifiable factors, such as experience and comfort with surveillance could be addressed. The sample is motivated to engage in behavioural health intervention.

Psychological impact of pancreatic cancer screening by EUS or magnetic resonance imaging in high-risk individuals: A systematic review

Background and Objectives:

There is an increasing global interest in screening programs aiming to detect pancreatic cancer (PC) in an early and potentially curable stage. Concerns still remain as to whether screening would confer any survival benefit. Another approach to evaluate the benefits of the pancreatic screening programs would be to consider its impact on the quality of life of the individuals who at risk of developing cancer. The aim of this systematic review was to investigate the current knowledge regarding the psychological impact of participation in routine screening for PC.

Methods:

A systematic literature search was carried out in January 2018 in three major databases which are as follows: PubMed, Scopus, and Web of Science. Cross-sectional and prospective studies evaluating the psychological aspects of screening in high-risk individuals were included in the study. For each study, the following data were recorded: name of first author, year of publication, study design, study population, aims, screening protocol, outcomes and instruments, main results, and summary of findings.

Results:

Six cohort studies and one cross-sectional study that addressed the psychological aspects of PC screening were included in the analysis. Overall, studies have shown that high-risk individuals have positive psychological outcomes from participating in PC screening programs.

Conclusions:

Although screening might not always be reassuring, it may improve individuals’ quality of life, and this should be an important aspect when considering PC screening.

German National Case Collection for familial pancreatic Cancer (FaPaCa) - acceptance and psychological aspects of a pancreatic cancer screening program

Background

Pancreatic cancer screening is recommended to individuals at risk (IAR) of familial pancreatic cancer (FPC) families, but little is known about the acceptance of such screening programs. Thus, the acceptance and psychological aspects of a controlled FPC screening program was evaluated.

Methods

IAR of FPC families underwent comprehensive counseling by a geneticist and pancreatologist prior to the proposed screening. Participating IAR, IAR who discontinued screening and IAR who never participated in the screening program were invited to complete questionnaires to assess the motivation for participating in surveillance, cancer worries, structural distress and experiences with participation. Questionnaires were completed anonymously to receive most accurate answers.

Results

Of 286 IAR to whom pancreatic ductal adenocarcinoma (PDAC) screening was recommended, 139 (48.6%) IAR regularly participated (group 1), 49 (17.1%) IAR (group 2) discontinued screening after median 1 (1–10) screening visits and 98 (34.2%) IAR (group 3) never underwent screening. The overall response rate of questionnaires was 67% (189/286) with rates of 100% (139 of 139 IAR), 49% (29 of 49 IAR) and 23.4% (23 of 98 IAR) for groups 1, 2 and 3, respectively. At least 93% of IAR felt adequately informed about the screening program after initial counseling. However, only 38.8% received knowledge of or the recommendation for PDAC screening by physicians. The reported cancer-related distress and the fear of investigations were highest in group 1, but acceptably low in all three groups. The main reasons to discontinue or not to participate in screening were the time efforts and travel costs (groups 2 and 3 48,7%).

Conclusion

Less than 50% of IAR regularly participate in a proposed PDAC screening program, although the associated psychological burden is quite low. Physicians should be educated about high risk PDAC groups and screening recommendations. Time and travel efforts must be reduced to encourage more IAR to participate in a recommended screening.

Relationship between individual and family characteristics and psychosocial factors in persons with familial pancreatic cancer

OBJECTIVE

Describe relationships between self-reported personal demographics or familial characteristics and psychosocial outcomes (Patient Reported Outcome Measurement Information System Global Health, Impact of Event Scale-Revised [pancreatic cancer risk-related distress], cancer risk perception, and cancer worry) in participants with inherited or familial pancreatic cancer risk.

METHODS

A multisite cross sectional survey of adults with elevated pancreatic cancer risk based on family history. All variables were summarized with descriptive statistics. To assess univariate associations, t test and chi-square/Fisher's exact test were used, and backward model selection was used in multivariable analysis.

RESULTS

Respondents (N = 132) reported moderate to high frequency of cancer worry and 59.3% perceived a 50% or more perceived lifetime risk for pancreatic cancer, which far exceeds objective risk estimates. Cancer worry was associated with female gender (P = .03) and pancreatic cancer risk specific distress (P = .05). Higher-risk perception was associated with having a high school education or less (P = .001), higher distress (P = .02), and cancer worry (P = .008) and family cancer death experience (P = .02). Higher distress was associated with experience as a caregiver to a seriously ill family member in the past 5 years (P = .006).

CONCLUSIONS

Individuals with inherited or familial pancreatic cancer risk experience cancer worry, distress, and have increased risk perception, particularly in the period following caring for a loved one with cancer. Routine evaluation of distress in this setting, as well as the development of supportive care resources, will help support patients living with risk for pancreatic cancer.

Factors associated with cancer worries in individuals participating in annual pancreatic cancer surveillance

It is important to adequately and timely identify individuals with cancer worries amongst participants in a pancreatic ductal adenocarcinoma (PDAC) surveillance program, because they could benefit from psychosocial support to decrease distress. Therefore, the aim of this study was to assess both psychosocial and clinical factors associated with cancer worries. High-risk individuals participating in PDAC-surveillance were invited to annually complete a cancer worry scale (CWS) questionnaire which was sent after counseling by the clinical geneticist (T0), after intake for participation in PDAC-surveillance (T1), and then annually after every MRI and endoscopic ultrasonography (EUS) (T2 and further). Analyses were performed to identify factors associated with cancer worries in the second year of surveillance (T3). We found a significant intra-individual decrease in cancer worries (β = −0.84, P < 0.001), nevertheless, 33 % of individuals had a CWS-score ≥14 at T3. We found one factor significantly associated with cancer worries at T3: having a family member affected by PDAC <50 years of age (β = 0.22, P = 0.03). The detection of a cystic lesion, a shortened surveillance interval, or undergoing pancreatic surgery did not lead to more cancer worries (P = 0.163, P = 0.33, and P = 0.53, respectively). In conclusion, this study identified ‘a family history of PDAC <50 years of age’ as the only predictor of cancer worries experienced after 2 years of surveillance in individuals at high risk of developing PDAC. This knowledge could help clinicians to timely identify individuals ‘at risk’ for high levels of cancer worries who would likely benefit from psychosocial support.

Familial pancreatic cancer: Concept, management and issues

Familial pancreatic cancer (FPC) is broadly defined as two first-degree-relatives with pancreatic cancer (PC) and accounts for 4%-10% of PC. Several genetic syndromes, including Peutz-Jeghers syndrome, hereditary pancreatitis, hereditary breast-ovarian cancer syndrome (HBOC), Lynch syndrome, and familial adenomatous polyposis (FAP), also have increased risks of PC, but the narrowest definition of FPC excludes these known syndromes. When compared with other familial tumors, proven genetic alterations are limited to a small proportion (< 20%) and the familial aggregation is usually modest. However, an ethnic deviation (Ashkenazi Jewish > Caucasian) and a younger onset are common also in FPC. In European countries, “anticipation” is reported in FPC families, as with other hereditary syndromes; a trend toward younger age and worse prognosis is recognized in the late years. The resected pancreases of FPC kindred often show multiple pancreatic intraepithelial neoplasia (PanIN) foci, with various K-ras mutations, similar to colorectal polyposis seen in the FAP patients. As with HBOC patients, a patient who is a BRCA mutation carrier with unresectable pancreatic cancer (accounting for 0%-19% of FPC patients) demonstrated better outcome following platinum and Poly (ADP-ribose) polymerase inhibitor treatment. Western countries have established FPC registries since the 1990s and several surveillance projects for high-risk individuals are now ongoing to detect early PCs. Improvement in lifestyle habits, including non-smoking, is recommended for individuals at risk. In Japan, the FPC study group was initiated in 2013 and the Japanese FPC registry was established in 2014 by the Japan Pancreas Society.

Surveillance for neoplasia in the pancreas

Despite its low incidence in the general population, pancreatic cancer is one of the leading causes of cancer-related mortality. Survival greatly depends on operability, but most patients present with unresectable disease. Therefore, there is great interest in the early detection of pancreatic cancer and its precursor lesions by surveillance. Worldwide, several programs have been initiated for individuals at high risk for pancreatic cancer. Their first results suggest that surveillance in high-risk individuals is feasible, but their effectiveness in decreasing mortality remains to be proven. This review will discuss which individuals are eligible for surveillance, which lesions are aimed to be detected, and which surveillance modalities are being used in current clinical practice. Furthermore, it addresses the management of abnormalities found during surveillance and topics for future research.

Advances in Hereditary Colorectal and Pancreatic Cancers

PURPOSE

Innovations in genetic medicine have led to improvements in the early detection, prevention, and treatment of cancer for patients with inherited risks of gastrointestinal cancer, particularly hereditary colorectal cancer and hereditary pancreatic cancer.

METHODS

This review provides an update on recent data and key advances that have improved the identification, understanding, and management of patients with hereditary colorectal cancer and hereditary pancreatic cancer.

FINDINGS

This review details recent and emerging data that highlight the developing landscape of genetics in hereditary colorectal and pancreatic cancer risk. A summary is provided of the current state-of-the-art practices for identifying, evaluating, and managing patients with suspected hereditary colorectal cancer and pancreatic cancer risk. The impact of next-generation sequencing technologies in the clinical diagnosis of hereditary gastrointestinal cancer and also in discovery efforts of new genes linked to familial cancer risk are discussed. Emerging targeted therapies that may play a particularly important role in the treatment of patients with hereditary forms of colorectal cancer and pancreatic cancer are also reviewed. Current approaches for pancreatic cancer screening and the psychosocial impact of such procedures are also detailed.

IMPLICATIONS

Given the availability of new diagnostic, risk-reducing, and therapeutic strategies that exist for patients with hereditary risk of colorectal or pancreatic cancer, it is imperative that clinicians be vigilant about evaluating patients for hereditary cancer syndromes. Continuing to advance genetics research in hereditary gastrointestinal cancers will allow for more progress to be made in personalized medicine and prevention.
