Prevalence of Asymptomatic Intraductal Papillary Mucinous Neoplasms in Healthy and Ill Populations Detected by Ultrasonography: A Single-Center Study of 6353 Outpatients
2019
OBJECTIVES: The aim of this study was to establish the prevalence of intraductal papillary mucinous neoplasms (IPMNs) without and with high-risk stigmata (HRS)/worrisome features (WF) and the epidemiologic association between IPMNs and other diseases. METHODS: Ultrasound examinations of outpatients were evaluated. The IPMN was confirmed by magnetic resonance imaging. The prevalence of IPMNs and HRS/WF IPMNs was calculated. The association between IPMNs and other diseases was studied. RESULTS: The prevalence rate of IPMNs was 3.4%. A total of 1,531,264 IPMNs were expected in Italian population (2.5%), whereas 2257 per 100,000 citizens (2.3%) were expected in the European standard population (ESP2013). The prevalence rates of HRS/WF IPMNs were 0.5%, 0.7%, and 0.6%, in our, the Italian, and the ESP2013 populations, respectively. A total of 432,881 and 620 HRS/WF IPMNs per 100,000 residents were expected in the Italian and the ESP2013 populations, respectively. The IPMN prevalence increased over 50 years of age (odds ratio [OR], 3.2; P < 0.001) and over 70 years of age (OR, 1.9; P < 0.001). Female sex was related to the presence of IPMNs (OR, 1.9; P < 0.001). CONCLUSIONS: Intraductal papillary mucinous neoplasms had a high prevalence in asymptomatic nonhospitalized populations. Age older than 50 years identified a possible risk category.
