Summary

At present, it is recommended to continue immunotherapy until progression or unacceptable toxicity.

However, only a minority of patients benefits from a durable response and most see the disease progress despite several months of control under immunotherapy. Multimodal approaches have been developed to improve their prognosis.

This study, randomized, open-label study aims to evaluate the impact of addition of ablative radiotherapy on OS of patients with NSCLC and oligometastatic lesions and treated by immunotherapy in first line (potentially associated with chemotherapy) or beyond. Stereotactic radiotherapy will be performed on a maximum of 5 residual hypermetabolic lesions seen on 18F-FDG PET / CT, in patients responding to immunotherapy (or with a stable disease) for at least 6 months.

Conditions

Interventions

RADIATION

SRT

Patients with a maximum of 5 residual hypermetabolic lesions observed on 18F- FDG PET / CT after a minimum of 6 months of immunotherapy are treated with SRT, in addition to their anti-PD-1 or anti-PD-L1 immunotherapy as it was administered before randomization in the trial, according to the standards. A maximum of 3 Brain metastases treatable in stereotactic radiotherapy will be included among these hypermetabolic lesions. Each lesion is treated with a total dose of 24 Gy delivered in 3 fractions of 8 Gy (isodose surface).

DRUG

Immunotherapy

Patients with a maximum of 5 residual hypermetabolic lesions observed on 18F- FDG PET / CT after a minimum of 6 months of immunotherapy continue their anti-PD-1 or anti-PD-L1 immunotherapy as it was administered before randomization in the trial, according to the standards.
