From: Optimal contouring of seminal vesicle for definitive radiotherapy of localized prostate cancer: comparison between EORTC prostate cancer radiotherapy guideline, RTOG0815 protocol and actual anatomy

SV-volume(cm3) Mean ± SD Median Range
VANAT-1 3.66 ± 0.92* 3.69 1.65 – 5.28
VRTOG 4.09 ± 0.92* 4.18 2.67 – 6.44
VEORTC-1 4.80 ± 1.18* 4.72 2.89 – 7.41
VANAT-2 6.23 ± 1.94 y 6.25 2.68 – 12.54

  1. Abbreviations: V ANAT-1/2 = volume of proximal 1-/2-cm SV CTV defined by actual anatomy; V RTOG = volume of proximal 1-cm SV CTV defined by RTOG0815; V EORTC-1/2 = volume of proximal 1-/2-cm SV CTV defined by EORTC guideline; *p < 0.001 for comparison between any two means of VANAT-1, VRTOG and VEORTC-1; yp < 0.001 for the comparison between VANAT-2 and VEORTC-2.
