Data on patient demographics, comorbidities, treatment, and histopathology were identified and collected. We evaluate intraclass correlation coefficient (ICC) and Bland\u2013Altman plot to test the agreement between the measurements. ICC were excellent with an ICC of 89% (95%CI 48%\u201399%). The mean\u2009\u00b1\u2009standard deviation of the distance from the anal verge to the distal part of the tumor was 7.73\u2009\u00b1\u2009.47 for flexible endoscopy and 6.21\u2009\u00b1\u20090.39 for MRI, with mean difference of 1.52 (<jats:italic>p<\/jats:italic>\u00a0\u02c2\u00a0.001).
