However, broader acceptance of this approach, particularly within some segments of medical oncology, remains limited. To address this, PSOGI initiated a multisociety consensus effort, involving multidisciplinary International Societies, to strengthen and expand the endorsement of CRS\u2010HIPEC for DMPM. Using the GRADE ADOLOPMENT approach, the expert panel systematically reviewed existing guidelines and evaluated the available evidence to reinforce the recommendation. The panel unanimously recommended CRS\u2010HIPEC for a carefully selected subset of DMPM patients, emphasizing that this approach offers the best potential for improved survival compared to systemic chemotherapy alone. Despite the very low certainty of evidence, a strong recommendation was issued, reflecting the panel's recognition of the life\u2010threatening feature of DMPM and the limited efficacy of systemic chemotherapy. This consensus also highlights the importance of centralized and expert\u2010driven care. The recommendation aligns with previous guidelines and underscores the critical need for broader acceptance of this treatment strategy in managing this rare and aggressive malignancy.<\/jats:p>","DOI":"10.1002\/jso.27947","type":"journal-article","created":{"date-parts":[[2024,11,28]],"date-time":"2024-11-28T23:54:02Z","timestamp":1732838042000},"page":"810-815","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Multisocietal
