Health-related quality of life and anxiety levels among patients under surveillance for intraductal papillary mucinous neoplasm

BACKGROUND: Because of the premalignant nature of intraductal papillary mucinous neoplasms (IPMNs), patients should undergo surveillance as long as they remain fit for surgery. This surveillance, with imaging and laboratory tests every 6 to 12 months, is expensive and may psychologically burden patients. This study aimed to determine the effects of IPMN surveillance on patients´ health-related quality of life (HRQoL) and anxiety levels. METHODS: We included a random subgroup of all IPMN patients undergoing a follow-up check-up at Helsinki University Hospital (HUH) between August 2017 and November 2018. Patients were asked to complete the 15D HRQoL and state-trait anxiety inventory (STAI) questionnaires just before and three months after an IPMN control. RESULTS: Among 899 patients in IPMN follow-up, 232 participated. The 15D HRQoL results showed differences in some IPMN patients’ 15 analyzed dimensions compared to a sex- and age-standardized general population cohort, but the clinical relevance of these differences appear doubtful. We detected no significant difference in the anxiety levels determined using the STAI questionnaires before or three months after the IPMN control. CONCLUSION: Surveillance should be less harmful than the risk of disease. Among our patients, the recommended IPMN follow-up carried minimal negative impact on patients’ HRQoL or anxiety levels. This result is important, because the number of patients under IPMN surveillance is rapidly increasing and the cancer risk among the majority of these patients remains small. Trial registration: The Surgical Ethics Committee of Helsinki University Hospital approved this study (Dnro HUS 475/2017) and it was registered at ClinicalTrials.gov (NCT03131076) before patient enrollment began.
