- Interobserver variation is quite severe even in the presence of guidelines Mourik et al. Radiother Oncol 94:286-291. 2010

- Guidelines can improve consistency among radiation oncologists performing target volume delineation for partial breast radiation therapy Wong et al. IJROBP 66:372-376. 2006 - Each institute should determine its interobserver variability with respect to CTV breast and CTV boost before implementing the delineation of target volumes by planning CT in daily practice Struikmans et al. Radiother Oncol 76:293-299. 2005
