    Abstract: Pancreatic cancer surveillance in high-risk individuals may lead to detection of pancreatic ductal adenocarcinoma (PDAC) at an earlier stage and with improved survival. This study evaluated the yield and outcomes of 20 years of prospective surveillance in a large cohort of individuals with germline pathogenic variants (PVs) in CDKN2A. METHODS Prospectively collected data were analyzed from individuals participating in pancreatic cancer surveillance. Surveillance consisted of annual magnetic resonance imaging with magnetic resonance cholangiopancreatography and optional endoscopic ultrasound. RESULTS Three hundred forty-seven germline PV carriers participated in surveillance and were followed for a median of 5.6 (interquartile range 2.3-9.9) years. A total of 36 cases of PDAC were diagnosed in 31 (8.9%) patients at a median age of 60.4 (interquartile range 51.3-64.1) years. The cumulative incidence of primary PDAC was 20.7% by age 70 years. Five carriers (5 of 31; 16.1%) were diagnosed with a second primary PDAC. Thirty (83.3%) of 36 PDACs were considered resectable at the time of imaging. Twelve cases (12 of 36; 33.3%) presented with stage I disease. The median survival after diagnosis of primary PDAC was 26.8 months, and the 5-year survival rate was 32.4% (95% CI, 19.1 to 54.8). Individuals with primary PDAC who underwent resection (22 of 31; 71.0%) had an overall 5-year survival rate of 44.1% (95% CI, 27.2 to 71.3). Nine (2.6%; 9 of 347) individuals underwent surgery for a suspected malignant lesion, which proved to not be PDAC, and this included five lesions with low-grade dysplasia. CONCLUSION This long-term surveillance study demonstrates a high incidence of PDAC in carriers of a PV in CDKN2A. This provides evidence that surveillance in such a high-risk population leads to detection of early-stage PDAC with improved resectability and survival.

    Abstract: 690 Background: Recent pancreatic cancer surveillance programs of high-risk individuals have reported improved outcomes. This study assessed to what extent outcomes of pancreatic ductal adenocarcinoma (PDAC) in patients with a CDKN2A/p16 pathogenic variant (PV) diagnosed during surveillance are better as compared to PDAC patients diagnosed outside surveillance. Methods: In a propensity score matched cohort using data from the Netherlands Cancer Registry, we compared resectability, stage and survival between patients diagnosed in surveillance with non-surveillance PDAC patients. Survival analysis were repeated after adjustment for lead-time bias. Results: Between January 2000 and December 2020, 43 762 patients with PDAC were identified from the NCR. Thirty-one patients with PDAC in surveillance were matched in a 1:5 ratio with 155 non-surveillance patients based on age at diagnosis, sex, and year of diagnosis. In total, 71% of patients in surveillance, as compared to 16% of non-surveillance patients underwent a surgical resection (OR 14.03; 95% CI, 5.92 – 35.85). In surveillance, 39% of patients was diagnosed with stage I cancer, as compared to 6% of non-surveillance PDAC patients (OR 0.10; 95% CI, 0.04 – 0.21). Patients in surveillance had a better prognosis, reflected by a 3-year survival of 32.4% and a median overall survival (OS) of 26.8 months vs. 1.4% 3-year survival and 5.3 months median OS in non-surveillance patients (HR 0.22; 95% 0.14 – 0.36). After adjustment for lead time, PDAC diagnosis in surveillance remained strongly associated with improved survival. Conclusions: Surveillance for PDAC in carriers of a CDKN2A/p16 PV results in earlier detection, increased resectability and improved survival as compared to non-surveillance PDAC patients.[Table: see text]
