Plan selection – rectum

Initial strategy plan selection: straightforward Only 1 CT scan – no extreme bladder/rectum fillings No need of algorithm But concerns: More complex target definition target volume compared to bladder and cervix? Larger patient numbers – more RTTs to be trained Dosimetric benefit given anatomy of target and OAR Implementation strategy:  Observer study to assess feasibility and support training and implementation (large number RTTs)  Dosimetric study to assess dose to OAR
