SBRT for Oligo-residual NSCLC After Treatment With PD-1/PD-L1 Immune Checkpoint Inhibitors

Patients will receive PD-1/PD-L1 inhibitors for up to 2 years or until confirmed progression or unacceptable toxicity. PD-1/PD-L1 inhibitors will be administrated as an intravenous(IV) infusion.

Patients with oligo-residual NSCLC after effective treatment with PD-1/PD-L1 inhibitors will be treated with curative-intent SBRT of residual lesions. The choice of dose-fractionation regimen is at the discretion of the treating radiation oncologist. PD-1/PD-L1 inhibitors will be withheld one day before the treatment and resumed within 2 weeks after completion of SBRT.
