Conclusion:

Phase 1 showed that:

a. Our worksheet allows for daily patient feedback and for RTTs and physicists to assess daily CBCT in relation to previous fractions, as well as observe trends in bladder volume that can indicate increasing acute bladder side effects. b. The new regime included more patient information and daily feedback, reinforcing that bladder volume is important and that we are in partnership with patients to achieve an optimal course of treatment. c. Our current definition of MB is inadequate. Phase 2 must address this issue. d. Repeating Phase 1 with new MB structures is necessary to properly assess our bladder filling regime.

Keywords: Acceptable bladder volume, assessing CBCT match
