What is the reasonable option for elderly patients with incidental pancreatic cystic neoplasms? Follow-up observation versus surgical resection

AIMS Pancreatic cystic neoplasms (PCN) with malignant potential are thought to be less aggressive than ordinary ductal adenocarcinoma, even in the setting of malignant transformation. Therefore, deciding whether or not to carry out surgery is very difficult, especially in elderly and asymptomatic patients, because of the high risk of perioperative morbidities. The aim of the present study was to examine clinical outcomes of PCN patients aged 65 years or older. METHODS This retrospective analysis included patients with incidentally detected PCN with follow-up durations >1 year. Patients diagnosed with obvious simple cysts, pseudocysts or pancreatic cancer and patients with a history of pancreatic disease were excluded from the study. RESULTS The present study included 201 patients (older group 104 patients ≥65 years; younger group 97 patients
