Objective:

To determine the long-term incidence of pancreatic cancer among patients with low-risk pancreatic cystic lesions (PCLs) and identify baseline clinical and imaging factors associated with cancer development, emphasizing the significance of these factors in clinical decision-making.

Key Findings:

• Low-risk PCLs are prevalent, but their exact risk of pancreatic cancer is unclear due to limited longitudinal studies, which complicates clinical decision-making.
• Current management of low-risk PCLs is heterogeneous and often based on expert opinion rather than strong evidence, leading to potential inconsistencies in patient care.
• There is significant variation among radiologists in recommending additional imaging for PCL management, highlighting the need for standardized protocols.

Interpretation:

The study highlights the need for an evidence-based approach to manage low-risk PCLs, given the uncertainty and variability in current clinical practices, which could significantly impact patient outcomes.

Limitations:

• The study is retrospective and may be subject to verification bias, which could affect the reliability of the findings.
• Exclusion of patients who underwent resection may limit generalizability, as these patients represent a specific subset of PCL management.
• Limited longitudinal data on low-risk PCLs may affect the accuracy of cancer risk assessment, necessitating further research.

Conclusion:

Establishing a standardized, evidence-based management protocol for low-risk PCLs is essential to improve patient outcomes and reduce unnecessary interventions, addressing the gaps identified in current practices.
