AB - This study analyzed the set-up error by the difference in Body Mass Index (BMI) and applied the
error to the existing treatment plan to compare the BMI determined dose for the small intestines and bladder
in colorectal cancer to study the usability of belly board. Twelve patients received radiation therapy before or
after surgery after being were diagnosed with colorectal cancer between August, 2014 and July, 2015. They were
divided into two groups based on BMI (high BMI = 24 kg/m2; low BMI or < 24 kg/m2) and each group was sub
classified on the use/ non-use of belly board (Group 1, belly board and low BMI; Group 2, no belly board and
low BMI; Group 3, belly board and high BMI; Group 4, no belly board and high BMI). For Group 1, the volume
of bladder V10 did not change with V20 2.13±0.83, V30 3.66±2.99 and V40 4.53±3.45 cc. The volume of the small
bowel V10 was 1.11±1.30 with V20 2.19±1.82, V30 2.55±2.25 cc and V40 2.75±2.55 cc (Group 2). In Group 3, V10
did not change with V20 11.73±14.94, V3015.08±19.78 and V40 19.40±23.92 cc while the volume of small bowel
V10 was 1.19±1.82, V20 16.22±24.36, V30 17.67±25.30 and V40 18.49±26.37 cc. In Group 4, V10 did not change
with V20 8.08±9.12, V30 15.45±7.63 and V40 19.53±9.61 cc while the volume of small bowel V10 was 0.73±0.86,
V20 7.13±5.38, V30 15.26±14.97 and V40 10.77±7.92 cc. The volume of bladder V10 did not change with
0.39±0.68, V20 12.33±9.98, V30 18.03±8.79 and V40 21.55±8.12 cc while the volume of small bowel, V10 was
18.38±17.00, V20 11.45±1.69, V30 23.67±20.79 and V40 36.17±31.70 cc.
