Feasibility investigation of prone position robotic radiosurgery treatment for dorsal metastasis

The combination of Adaptive Radiotherapy (ART) and VMAT allows to create more conformal plans for patients with bladder cancer without risk of missing target during changes of bladder volume and shape. Relative position of small bowel is influenced by the volume of treated bladder. Recent reviews demonstrated the advantages of using ART in bowel sparing during bladder irradiation. The aim of this study was to assess feasibility of simultaneous sparing of bone marrow, small bowel and rectum using combination of ART and VMAT.
