The cohort was divided into patients treated by CRS and HIPEC and those treated by CRS without HIPEC (including CRS only or maximal tumour debulking (MTB)). Main outcomes included surgical outcomes, survival, and quality of life. Groups were compared using non\u2010parametric tests and log\u2010rank test was used to compare survival curves.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>403 had CRS and HIPEC, 25 CRS only and 15 MTB.

When HIPEC is not utilized, due to significant residual disease or comorbidity precluding safe delivery, CRS alone is associated with good outcomes. Hospital stay and complications are acceptable but not significantly different to the CRS and HIPEC group. CRS alone is a complex intervention requiring comparable resources with good outcomes. In view of our findings \u2018intention to treat\u2019 with CRS and HIPEC should be the basis for resource allocation and funding.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ans.18933","type":"journal-article","created":{"date-parts":[[2024,3,7]],"date-time":"2024-03-07T10:51:15Z","timestamp":1709808675000},"page":"628-633","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Complexity
