I'd treat 50-55 Gy/5 fractions or could consider fractionating o...

Ablative RT 10 Gy x 5 (MRgRT) or 67.5 Gy in 15 fx (Linac) to primary + SBRT to the met. Patients with lung only mets have more indolent metastatic disease. Tail primary tumor progression does not cause as much morbidity as head lesions, so QOL benefit may be lower, and OS benefit is not clear; howev...
