• Note (General): To determine the predictive factors affecting uterine movement during radiotherapy (RT), we quantified interfraction; uterine movement using computed tomography (CT) and cone-beam CT (CBCT). A total of 38 patients; who underwent definitive RT for cervical cancer were retrospectively analyzed. We compared pre-RT planning CT; (n = 38) and intratreatment CBCT (n = 315), measuring cervical and corporal movement in each direction. Correlations between uterine movement and volume changes of the bladder and rectum on all CBCT scans were; analyzed using Spearman rank correlation analysis. Relationships between the mean uterine movement and patient; factors were analyzed using the Mann–Whitney test. The mean corpus movement was: superior margin (cranio–; caudal direction), 7.6 ± 5.9 mm; anterior margin (anteroposterior direction), 8.3 ± 6.3 mm; left margin (lateral direction),; 3.3 ± 2.9mm; and right margin (lateral direction), 3.0 ± 2.3 mm. Generally, the mean values for cervical; movement were smaller than those for the corpus. There was a significant, weak correlation between changes in; bladder volume and the movement of the superior margin of the corpus (ρ = 0.364, P < 0.001). There was a significant; difference in movement of the superior margin of the corpus between the subgroups with and without a; history of previous pelvic surgery (P = 0.007). In conclusion, change in bladder volume and a history of previous; surgery were significantly related to intrafractional corpus movement; however, our observations suggest that the; accurate prediction of uterine movement remains challenging.; 学位論文
