Introduction: Mucinous cystic neoplasms (MCN) of the pancreas are rare mucin-producing cystic tumours. They are often incidentally found in middle-aged women and are typically located in the pancreatic body or tail. MCN has reported rates of malignant transformation between 4 – 12% and surgical resection is frequently performed. There is no cleared defined management strategy for MCN. Limited data exists about management of MCN in Australia. The aim of this study was to identify patients diagnosed with MCN, those with malignant transformation, characteristics, management and analyse outcomes. Methods: A retrospective study was conducted using a prospectively maintained institutional pancreatic REDCap database (n = 1528) between 2013 and 2023. Patients who underwent curative-intent pancreatectomy for pancreatic cysts and histological diagnosis of MCN were included. Patients with synchronous/metachronous cancer or those who received neoadjuvant treatment were excluded. The following data were collected: patient demographics; symptoms; tumour location; cyst size; presence of mural nodules; serum CA19-9 and CEA; diagnostic modality; surgical approach (open or laparoscopic, with or without spleen preservation); final histology findings; morbidity and mortality at 30 days according to the Clavien-Dindo classification; use of adjuvant chemotherapy or radiotherapy; and diagnosis and management of exocrine and endocrine insufficiency. Results: There is limited data available on prevalence, actual management and outcomes in patients with MCN in a local setting. Conclusion: This is the first Australian study on MCN to our knowledge. Further studies are necessary in this area of study to help identify patients who may benefit from surgical resection versus observation.
