- Abstract
Purpose. To compare the prone position on a flat table vs an “All in one” belly board device (AIO BBD) in rectal cancer patients (RCPs). Material and methods. Fifteen RCPs scheduled for irradiation were scanned in the two evaluated positions. After tomography, they completed a questionnaire concerning positioning. The dose-volume histograms (DVHs) for the small bowel and bladder were compared for both immobilization methods and setup accuracy was analyzed in electronic portal imaging devices (EPIDs) and X-ray volume imaging (XVI) procedures. Results. AIO BBD was accepted by the majority of RCPs and provided better DVHs for the small bowel than the prone position on a flat table. The setup reproducibility was within tolerance limit for patients with BMI ≤ 29 kg/m2. Patients with obesity regarded AIO BBD as uncomfortable and they presented mean setup shifts out of the tolerance limit in the Y axis — 5.9 mm. Conclusions. The AIO BBD should be recommended for RCPs, especially for those with BMI ≤ 29 kg/m2.
