Table 1. Dose constraints for organs at risk at five fractions of stereotactic body radiotherapy.

Dx cc = dose received by x cc of organ volume; Dmean = dose received by the mean value of organ volume

Duodenum	D0.1 cc <33 Gy (optimal), <35 Gy (mandatory)
Kidney	Dmean <10 Gy D200 cc <17.5 Gy
Liver	D700 cc <15 Gy
Stomach	D0.1 cc <33 Gy (optimal), <35 Gy (mandatory) D10 cc <25 Gy D50 cc <12 Gy
Small bowel	D0.1 cc <30 Gy (optimal), <35 Gy (mandatory) D10 cc <25 Gy
