Mesorectum motion showed no significant correlation with bladder volume changes but was significantly associated with rectal volume (<i>r</i> = 0.566; <i>p</i> &lt; 0.001 in the superior mesorectum). Anterior mesorectum motion was larger compared to other directions, particularly in the superior region, with systematic and random variations of 4.4 and 3.5 mm. Using the van Herk formula, PTV margins for the anterior mesorectum were 5.8, 4.9, and 3.3 mm for the superior, middle and inferior regions, respectively.
