Mistakes in pancreatic cystic neoplasms and how to avoid them

Marco Del Chiaro, Juan Enrique Dominguez-Munoz, Giovanni Marchegiani

Summary

AI Generated

Pancreatic cystic neoplasms are frequent lesions with varying biological behaviour that require tailored management to balance cancer prevention against overtreatment.

Pancreatic cystic neoplasms may be present in 2–45% of the general population and prevalence increases with age
Different types of pancreatic cystic neoplasms range from benign to malignant and require different surveillance and therapeutic approaches
Correct management is critical for avoiding progression to cancer while preventing unneeded follow-up, unnecessary invasive diagnostic procedures, and overtreatment

Abstract

Pancreatic cystic neoplasms (PCN) are a frequent and clinically challenging condition. PCN prevalence increases with age and reports estimate that they may be present in 2–45% of the general population. In addition, the biological behaviour of the various types of PCN differs (ranging from benign to malignant [table 1]), requiring different surveillance and therapeutic approaches. Correct management of PCN is, therefore, critical for avoiding progression to cancer, but at the same time avoiding unneeded close and long-term follow-up, unnecessary invasive diagnostic procedures and overtreatment.

Guideline

ABSTRACT

Background

Pancreatic cancer remains one of the most lethal cancers despite extensive efforts and research conducted over the past decades. To effectuate groundbreaking improvements in pancreatic cancer treatment, interdisciplinary and international collaboration is essential. Evidence-based guidelines, including state-of-the-art evidence and expert opinion, are crucial to guide medical specialists, researchers, and patients, especially on issues where consensus is still lacking. This article describes the methodological protocol for the development of the European Multidisciplinary Evidence-Based Guideline on Pancreatic Cancer. The guideline aims to identify current knowledge gaps on pancreatic cancer management, develop questions based on these knowledge gaps, and answer these questions with evidence-based recommendations supplemented, when evidence is lacking, with expert advice for treatment and future research.

Methods

This guideline development protocol is developed according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. The process is structured into six stages: First, 13 theme-based multidisciplinary working groups are established, comprising representatives from 30 European medical and patient societies. Second, these working groups identify the most relevant current knowledge gaps on pancreatic cancer within their theme and formulate key questions. Third, the available evidence to answer these key questions is obtained through systematic reviews and the certainty of evidence is assessed using the GRADE approach. Fourth, recommendations are developed based on the available evidence. Fifth, all participants reach consensus on the recommendations through a modified Delphi process. Sixth, the recommendations are discussed during an open conference, including an external validation committee.

Discussion

This methodological protocol of the European Multidisciplinary Evidence-Based Guideline on Pancreatic Cancer is designed to identify key knowledge gaps across 13 themes and formulate evidence-based recommendations. This guideline initiative unites 30 European medical and patient societies for pancreatic cancer.

Summary

Methodological protocol of an international multi-disciplinary guideline involving 30 European medical and patient societies.
This protocol highlights the six stages of the guideline development process, adhering to the key principles of the GRADE methodology, and thereby aims to maximise transparency and methodological quality.
With addressing knowledge gaps, this guideline will uncover areas with limited evidence. A priority rating for research needs, based on a survey, will be established, highlighting areas where future research is most warranted.
