Despite this, pragmatic unbiased outcome data is limited. This study aimed to investigate national outcomes associated with W&amp;W in Aotearoa New Zealand (AoNZ).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A national retrospective <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"https:\/\/www.sciencedirect.com\/topics\/medicine-and-dentistry\/cohort-analysis\">study<\/jats:ext-link> of patients with adenocarcinoma of the rectum managed with a W&amp;W approach between January 2015 and December 2022 in AoNZ was performed by STRATA, a student and trainee led collaborative network. The Cancer Registry and the New Zealand Ministry of Health National Minimum Data Set were linked to identify patients who had rectal cancer and who were treated with neoadjuvant therapy but not rectal resection.

The 2\u2010year cumulative incidence of local regrowth was 18.2% (95% CI 10.7%\u201325.1%), of which 92% was present in the bowel wall, and 68% underwent surgery, all with curative intent. The 2\u2010year cumulative distant metastasis rate was 8.8% (95% CI 3.0%\u201314.2%) and the 2\u2010year overall survival was 94.8% (95% CI 90.4%\u201399.4%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This nationwide study of a W&amp;W approach has clinical outcomes similar to the international literature.
