Hyperthermic intraperitoneal chemotherapy (HIPEC) offers a biologically rational strategy to eradicate occult intraperitoneal tumour cells by exposing the peritoneal cavity to heated cytotoxic agents with enhanced penetration and synergistic thermal cytotoxicity. Although widely used with cytoreductive surgery for established PM, its prophylactic or adjuvant role in non\u2010metastatic T4 disease remains uncertain. Randomized evidence is conflicting and divergent outcomes may be explained by a mechanistic triad encompassing: (1) timing of intraperitoneal drug exposure relative to early tumour implantation and adhesion formation; (2) pharmacological, thermal, and dosing characteristics of the HIPEC regimen, including its most often single administration; and (3) underlying biological heterogeneity within T4 tumours. Thus, HIPEC for T4 colon cancer remains promising in selected patients, and it may be established as routine if ongoing studies rigorously define timing, agent selection and biomarker\u2010driven patient stratification.<\/jats:p>","DOI":"10.1111\/codi.70393","type":"journal-article","created":{"date-parts":[[2026,2,2]],"date-time":"2026-02-02T09:17:50Z","timestamp":1770023870000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Time to define the role of hyperthermic intraperitoneal chemotherapy (HIPEC) in\n                    <scp>T4<\/scp>\n                    colon cancer"],"prefix":"10.1111","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3808-0774","authenticated-orcid":false,"given":"Mina","family":"Sarofim","sequence":"first","affiliation":[{"name":"Department of Colorectal Surgery Liverpool Hospital  New South Wales Australia"},{"name":"Innovation, Surgical Teaching and Research (iSTAR) Unit  Liverpool Hospital New South Wales Australia"},{"name":"School of Clinical Medicine University of New South Wales  New South Wales Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,2,2]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1245\/s10434-022-11472-w"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.3389\/fsurg.2020.590452"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejso.2021.05.009"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm12206443"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(20)30599-4"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12957-024-03386-6"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S2468-1253(19)30239-0"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.22.02644"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamasurg.2023.0662"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(20)30322-3"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1089\/lap.2016.0396"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejso.2024.107958"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1038\/nm.3967"}],"container-title":["Colorectal Disease"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/codi.70393","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/codi.70393","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/codi.70393","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,8]],"date-time":"2026-03-08T17:04:50Z","timestamp":1772989490000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/codi.70393"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,2]]},"references-count":13,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2026,2]]}},"alternative-id":["10.1111\/codi.70393"],"URL":"https:\/\/doi.org\/10.1111\/codi.70393","archive":["Portico"],"relation":{},"ISSN":["1462-8910","1463-1318"],"issn-type":[{"value":"1462-8910","type":"print"},{"value":"1463-1318","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,2]]},"assertion":[{"value":"2025-12-04","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-01-20","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-02-02","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70393"}}
