Table 5 Details of the dosimetric unacceptable deviations of HA-WBRT according to RTOG 0933 dosimetric constraints (22)

From: Quality assurance analysis of hippocampal avoidance in a melanoma whole brain radiotherapy randomized trial shows good compliance

Patient Hippo UD Value Max value Excess over 0933 UD as percentage Comments
1 Right Dmax
(> 17 Gy)
17.85 Gy 5.0% RT given prior to RTOG 0933 constraints being published
2 Right Dmin
(> 10 Gy)
10.4 Gy 4.0% RT given prior to RTOG 0933 constraints being published
3 Left Dmax
(> 17 Gy)
17.24 Gy 1.4% Multiple dosimetry has been realized to decrease the Dmax on left hippocampus. This patient had D2%Left_hippo of 14.05 Gy
