Surveillance Discontinuation in 5 Year Stable Trivial Branch Duct Intraductal Papillary Mucinous Neoplasms

Rövid összefoglaló (regiszter, angolul)

BACKGROUND: Patients with trivial branch duct intraductal papillary mucinous neoplasm (BD IPMN) which remain s stable over 5 years reportedly do not have an increased risk of developing pancreatic cancer (PC) compared to the general population. In these patients, d iscontinuation of surveillance seems feasible . However, prospective studies to confirm the safety of this approach are lacking. AIM: To assess whether current surveillance policies for stable, trivial BD IPMN can be discontinued safely after 5 years of follow up . METHODS: TRIVIAL is an international prospective multicenter single arm trial exploring discontinuation of surveillance in patients with at least 5 years stable trivial BD IPMN. The trial will include 394 adult patients at least 70 years of age with BD IPMN ≤ 30 millimeter without worrisome features or high risk stigmata during 5 years. The primary endpoint is rate of PC and futile surgery (i.e., surgery for low grade dysplasia IPMN or other non malignant pathology) during 5 year follow up. The predefined target is a rate of 1% and below 3%. STRENGTHS: The burden for patients to participate in this trial is negligible. P atients will only be asked to answer self reported digital surveys once per year during five years . The potential benefits for patients are twofold: the psychological impact of potentially unnecessary surveillance will be spared to patients , whereas the socio economic burden of repeated imaging will be avoided. Moreover, the study will provide data contributing to the development of new, evidence based surveillance strateg ies At the end of follow up patients undergo MRCP to assess disease course (i.e., development of worrisome features, high risk stigmata, PC). LIMITATIONS: The most prominent risk of IPMN is the development of pancreatic cancer However this risk will not be omitted fully by the TRIVIAL trial eligibility criteria as participants still have the same risk as the general population. This requires adequate counselling
