Adaptive radiotherapy: Strategies and benefits depending on tumor localization

2019, Practical Radiation OncologyCitation Excerpt :Turner et al. recommend using a margin of at least 2 cm to account for interfraction bladder volume variability.6 The region of the bladder with the largest magnitude of volume variability is the dome because of the superior and anterior displacement of the bladder wall in response to filling.5,7,8 Even for less invasive tumors, this recommendation seems standard.

2015, Clinical Radiation OncologyImage guided radiation therapy for bladder cancer: Assessment of bladder motion using implanted fiducial markers
2014, Practical Radiation OncologyCitation Excerpt :Comparison between the average difference in mm obtained from 2D registrations (radiographs to DRRs) and from 3D registrations (kVCBCT to planning scan) can be found in Fig 4 (initial phase) and Fig 5 (boost phase). The variation in size and position of the bladder during RT has been demonstrated in previously published imaging studies involving bladder cancer patients undergoing RT.12-16 Those studies are summarized in Table 1. Our data reveal observations similar to those from previous studies, yet is unique in that we utilized daily on-board imaging using implanted fidutial markers to verify organ motion.
