Table 1. Volume and dose of radiation to target tissue.

Parameter HR-CTV IR-CTV
Volume (cc) 40 (16–89) 100 (46–113)
V100 (%, ISBT alone) 96.7 (81.9–99.2)
D90 (Gyα/β10, ISBT alone) 45 (33–54) 30 (20–37)
D100 (Gyα/β10, ISBT alone) 26 (20–35) 16 (7–22)
D90 (Gyα/β10, ISBT+EBRT) 94 (83–104) 77 (70–87)
D100 (Gyα/β10, ISBT+EBRT) 75 (66–84) 65 (57–72)

HR-CTV, high-risk clinical target volume; IR-CTV, intermediate-risk clinical target volume; ISBT, interstitial brachytherapy; EBRT, external beam radiotherapy; D100, the minimal target dose; D90, dose received by at least 90% of the volume; V100, the volume treated with the prescription dose. All values are presented as median (range).
