While surgical resection is the only treatment option with curative intent, most patients die of locoregional and\/or distant recurrence. The prognostic impact of the resection margin status has received much attention. However, the evidence is almost exclusively related to pancreatoduodenectomies, while corresponding data for distal pancreatectomy specimens are limited. The key data, such as the rate of microscopic margin involvement (\u201cR1\u201d), the site of margin involvement, and the impact of R1 on patient outcome, are divergent between studies and do not currently allow any general conclusions. The main reasons for the variability in the published data are the small size of the study cohorts and their heterogeneity, as well as the marked divergence in pathology examination practices. The latter is a consequence of the lack of concrete guidance, both for grossing and microscopic examination. The increasing administration of neoadjuvant chemo(radio)therapy introduces a further factor of uncertainty as the conventional definition of a tumour-free margin (\u201cR0\u201d) based on 1 mm clearance is inadequate for these specimens. This review discusses the published data regarding the prognostic impact of margin status in distal pancreatectomy specimens along with the challenges and uncertainties that are related to the assessment of the margins.<\/jats:p>","DOI":"10.3390\/curroncol29090515","type":"journal-article","created":{"date-parts":[[2022,9,14]],"date-time":"2022-09-14T20:50:45Z","timestamp":1663188645000},"page":"6551-6563","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Prognostic Impact of Resection Margin Status on Distal Pancreatectomy for Ductal Adenocarcinoma"],"prefix":"10.3390","volume":"29","author":[{"given":"Maia Blomhoff","family":"Holm","sequence":"first","affiliation":[{"name":"Department of Pathology, Faculty of Medicine, University of Oslo, 0372 Oslo, Norway"},{"name":"Department of Pathology, Oslo University Hospital, 0424 Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1111-9715","authenticated-orcid":false,"given":"Caroline Sophie","family":"Verbeke","sequence":"additional","affiliation":[{"name":"Department of Pathology, Faculty of Medicine, University of Oslo, 0372 Oslo, Norway"},{"name":"Department of Pathology, Oslo University Hospital, 0424 Oslo, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11","DOI":"10.1038\/s41571-018-0112-1","article-title":"Optimizing the outcomes of pancreatic cancer surgery","volume":"16","author":"Strobel","year":"2019","journal-title":"Nat.
