OBJECTIVES: The aim of this study was to compare the prevalence of cystic pancreatic lesions and their natural behavior in 2 distinct high-risk groups for developing pancreatic ductal adenocarcinoma (PDAC): (1) carriers of a mutation that predisposes to PDAC and (2) individuals without a known gene mutation but with a family history of PDAC (familial pancreatic cancer [FPC]). METHODS: Pancreatic surveillance by annual magnetic resonance imaging and endoscopic ultrasound was performed in individuals with an estimated lifetime risk of developing PDAC of 10% or greater. Progression of a lesion was defined as growth 4 mm or greater or the development of worrisome features. RESULTS: We included 186 individuals: 98 mutation carriers and 88 FPC individuals (mean follow-up, 51 months). Individuals with FPC were significantly more likely than mutation carriers to have a pancreatic cyst 10 mm or greater (16% vs 5%, P = 0.045). Pancreatic cysts detected in mutation carriers, however, were significantly more likely to progress than those in FPC individuals (16% vs 2%, P = 0.050). CONCLUSIONS: This study provides evidence that the prevalence and growth characteristics of pancreatic cysts differ between distinct high-risk groups: individuals with FPC have a higher prevalence of pancreatic cysts 10 mm or greater, whereas cysts in mutation carriers are more likely to progress. These observations may help to develop more optimally tailored surveillance strategies in specific high-risk populations.

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

Background: When assessing the feasibility of surveillance for pancreatic cancer (PC), it is important to address its psychological burden. The aim of this ongoing study is to evaluate the psychological burden of annual pancreatic surveillance for individuals at high risk to develop PC. Methods: This is a multicenter prospective study. High-risk individuals who undergo annual pancreatic surveillance with magnetic resonance imaging (MRI) and endoscopic ultrasound (EUS) were invited to complete questionnaires to assess motivations for participating in surveillance, experiences with participation, perceived PC risk, topics of concern, and psychological distress. Questionnaires were sent after intake for participation (Ti), after the first MRI and EUS (T2), and after the MRI and EUS 1 (T3), 2 (T4), and 3 years (T5) after first surveillance. Results: In total, 140 out of 152 individuals returned one or more of the questionnaires (response 92%); 477 questionnaires were analyzed. The most frequently reported motivation for participating in surveillance was the possible early detection of (a precursor stage oi) cancer (95-100%). Only a minority of respondents experienced MRI and EUS as uncomfortable (10% and 11%, respectively), and respondents dreaded their next EUS investigation less as surveillance progressed. Respondents' cancer worries decreased significantly over time, and both their anxiety and depression scores remained stable and low over the 3-year period of follow-up. Conclusions: The psychological burden of pancreatic surveillance is low at all assessments. Therefore, from a psychological point of view, participation of high-risk individuals in an annual pancreatic surveillance program is feasible. Copyright (C) 2015 John Wiley & Sons, Ltd.
