Predictors of Toxicity Associated With Stereotactic Body Radiation Therapy to the Central Hepatobiliary Tract

VBED1072, VBED1066, and DmeanBED10 to cHBT are associated with HB toxicity. We suggest VBED1072 < 21 cm3 (5-fraction: V40 < 21 cm3; 3-fraction: V33.8 < 21 cm3), VBED1066 < 24 cm3 (5-fraction: V37.7 < 24 cm3; 3-fraction: V32 < 24 cm3) as potential dose constraints for the cHBT when clinically indicated.
