[Management of the Peutz-Jeghers Syndrome].

The current evidence to guide management of Peutz-Jeghers Syndrome (PJS) is sparse. Here we summarise the European guidelines that were published in 2021 by the EHTG (European Hereditary Tumour Group), extended with new evidence on some aspects of clinical management that have been generated since then. EHTG with this revised guideline has updated and extended their own previous expert opinion guideline from 2010. For this purpose, all published literature was systematically screened and the level of evidence determined by using the GRADE methodology (Grading of Recommendations Assessment. Development and Evaluation). This was followed by a Delphi process and the consensus for a statement was achieved if the voting committee reached ≥ 80% approval.The only other more recently published guidelines encountered only addressed the clinical management of gastrointestinal and pancreatic manifestations of PJS. These recommendations were reviewed and adopted, since no further relevant literature was identified in the systematic literature search. However, additional questions were identified and formulated into recommendations after following the described process. It may be stated that 10 years after the predecessor guideline, new evidence has been sparse. As with all rare diseases, a call for more collaborative studies must here be made in order to improve patient management by addressing open clinical questions and generating collaborative evidence with increased case numbers, both nationally and internationally. With the limited published evidence, these European guidelines are the most current reference for management of PJS patients.
