Psychological distress in patients under surveillance for intraductal papillary mucinous neoplasms of the pancreas: The "Sword of Damocles" effect calls for an integrated medical and psychological approach a prospective analysis.

Introduction: Most intraductal papillary mucinous neoplasms (IPMNs) of the pancreas can be safely surveilled. Their psychological impact is not known. The aim of this study is to obtain a psychological profile of patients under surveillance and compare the results to patients undergoing surgery.

Methods: Patients under surveillance for IPMNs evaluated between 2017 and 2019 at the pancreatic cysts clinic of The Pancreas Institute of Verona were compared to patients undergoing surgery for the same disease. Patients with high-risk stigmata were excluded in both groups. Patients were profiled with the Barratt Simplified Measure of Socio-Economic Status (BSMSS), the Brief Coping Orientation to Problems Experienced (Brief-COPE), the Perceived Stress Scale (PSS), the Symptom Checklist-90 and the Short Form Health Survey (SF-36). Age, sex, BSMSS and Brief-COPE were used to match patients with the propensity score as potential sources of bias.

Results: Two hundred patients were profiled. After the matching, 74 patients under surveillance were compared to 74 patients who underwent surgery. Patients under surveillance reported significantly increased scores for symptoms such as somatization (0.71 vs. 0.54, p = 0.032), depression (0.45 vs 0.31, p = 0.047) and anxiety (0.45 vs. 0.27, p = 0.002). They also reported a reduced health perception in the domain of physical role functioning (54 vs. 68, p = 0.046).

Conclusion: Patients under surveillance for a presumed IPMN experience anxiety and stress and feel less healthy than do patients undergoing surgery. This reduction in quality of life should always be taken into account and warrants an integrated medical-psychological approach in selected cases.
