The QUADAS-2 tool assessed the risk of bias. Pooled sensitivity, specificity, and diagnostic odds ratio (DOR) were calculated using a bivariate random-effects model. Subgroup analyses explored the influence of CT techniques, slice thickness, and study design on diagnostic performance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The meta-analysis included forty-four studies. CT demonstrated 83% sensitivity (95% CI, 79\u201386%) and 70% specificity (95% CI, 66\u201374%) for detecting pT3-T4 tumors (DOR: 10.0). For pT3cd-T4 (&gt;\u20095\u2009mm muscularis propria invasion), sensitivity was 67% (61\u201373%), specificity 88% (83\u201392%) and DOR 13.7 (9.0\u201321.0). Detection of pN+ yielded 64% sensitivity (60\u201368%), 67% specificity (62\u201372%) and DOR of 3.5 (3.0\u20134.2). Sensitivity for extramural venous invasion (EMVI+) was 49% (41\u201356%), with 77% specificity (67\u201384%) and DOR 3.0 (2.0\u20134.4). Studies with &lt; 5\u2009mm slice thickness showed higher sensitivity but lower specificity.
