In tumour node metastasis (TNM)8, the definition became stricter as TNM7\u2019s previous requirement for absence of lymphatic tissue was expanded to also include nerve and vascular tissue. TNM8 has been criticised for its limited prognostic value. This study aimed to compare prognostic differences for patients with colorectal cancer with tumour deposits staged with TNM7 and TNM8.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This national retrospective cohort study included patients with colorectal cancer who underwent surgical resection in 2011\u20132014 and 2017\u20132019. Exclusion criteria were metastatic stage IV disease, non-radical or non-curative surgery, unstated tumour deposit status, or early (\u2264 30 days) mortality. Univariable, multivariable, and interaction term Cox regression analyses examined differences in overall survival and distant metastasis between TNM7 and TNM8 stagings. Multivariable models were adjusted for age, gender, American Society of Anesthesiologists score, number of positive lymph nodes, TNM stage, neoadjuvant, and adjuvant treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of 19 413 patients operated on during 2011\u20132014 and 15 027 during 2017\u20132019, 23 966 were included. The TNM7 cohort had 1225 (9.5%) patients with tumour deposits, and the TNM8 cohort had 1407 (12.7%). There was an improved 5-year distant metastasis-free survival for patients with tumour deposits (hazard ratio 2.35 (95% confidence interval 2.14 to 2.58)) in the TNM8 cohort, but no benefit in overall survival, compared with patients in the TNM7 cohort. Interaction analysis revealed no prognostic difference associated with tumour deposit status between the two TNM editions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
