What dose constraints would you use for head and neck SBRT in a previously untreated field?
BR-001 allows treatment of oligometastatic disease in cervical lymph nodes but provides few dose constraints for SBRT in the head and neck. (Most of the literature on SBRT in the head and neck is in the setting of re-irradiation.)
Answer from: Radiation Oncologist at Academic Institution
The use of SBRT as a primary modality in patients who have not undergone previous irradiation and are not felt to be candidates for surgery or definitive chemoradiation varies institutionally, with some preferring to treat with hypofractionated regimens (particularly when they are candidates for che...

Answer from: Radiation Oncologist at Community Practice
At my current institution, we set our constraints for SBRT in unirradiated H&N by using BED calculations with an alpha/beta of 3 for normal tissues. So the constraint will vary if you use 1 vs 3 vs 5 fractions. I think others follow a similar approach, or use some variation of the validated cons...
