"A biological effective dose (BED) ≥125 Gy10 should be administered when constraints to the organs at risk (OARs) are respected \[10\]; if not possible, a BED schedule no lower than 100 Gy10 should be administered. In compliance with these instructions, treatment schedules, total dose and fractionation will be prescribed according to the clinical practice of each participating Center. The constraints for the organs at risk will be respected according to the available data.~In any case, biological effective dose (BED) ≥125 Gy10 should be administered when constraints to the organs at risk (OARs) are respected; if not possible, a BED schedule no lower than 100 Gy10 should be administered.~SABR will be administered before systemic treatment start, or before starting the second systemic treatment cycle at the latest."
