Summary
Increased detection of pancreatic cystic neoplasms (PCNs) requires tailored management. Optimal treatment for PCNs, including intraductal papillary mucinous neoplasms (IPMNs), depends on cyst type, size, and patient factors for improved outcomes.
Area of Science:
- Gastroenterology and Hepatology
- Surgical Oncology
- Diagnostic Imaging
Background:
- Pancreatic cystic neoplasms (PCNs) detection has risen due to advanced imaging.
- Management strategies for PCNs, particularly intraductal papillary mucinous neoplasms (IPMNs), have evolved.
- Existing IPMN treatment guidelines lack consensus, necessitating updated clinical approaches.
Purpose of the Study:
- To review the current epidemiology and malignancy risk of PCNs.
- To identify key factors influencing treatment decisions for PCNs.
- To propose optimal management algorithms for PCNs and IPMNs from a clinical perspective.
Main Methods:
- Comprehensive literature review of published studies.
- Inclusion of authors' original research and clinical experience.
- Analysis of diagnostic and prognostic factors for PCNs.
Main Results:
- Serous cystic neoplasms are typically benign and require observation.
- Mucinous cystic neoplasms and solid pseudopapillary neoplasms necessitate surgical intervention.
- Branch duct-type IPMNs <3 cm are often dormant, but larger or growing lesions require vigilant monitoring due to malignancy risk.
Conclusions:
- PCN management must be individualized based on cyst type, size, growth, and malignancy potential.
- Surveillance strategies should be tailored according to lesion size and characteristics.
- A personalized approach integrating lesion assessment and patient factors, potentially aided by nomograms, is crucial for optimal treatment selection (surgery vs. surveillance).
