Overview
Brief Summary
For patients with non-small cell lung cancer and more than five metastatic lesions (non-oligometastatic disease), does radical treatment of the primary lung lesion, in addition to pharmacotherapy, also provide benefits in terms of progression-free survival (PFS) and local control? Currently, there is limited clinical research on combining pharmacotherapy with radiotherapy for the primary lesion in non-oligometastatic patients. Therefore, this study aims to investigate whether radical radiotherapy targeting the primary lung lesion, in addition to pharmacotherapy, can improve local control and survival in non-oligometastatic patients, and whether the associated toxicities are acceptable.

- •Patients with poor compliance; Patients deemed unsuitable for participation in this trial by the investigator.
Arms & Interventions
Pharmacotherapy group
For patients positive for driver gene mutations, first-line targeted therapy with or without chemotherapy is recommended according to NCCN guidelines. For patients negative for driver gene mutations, first-line immunotherapy combined with chemotherapy is recommended according to NCCN guidelines.
Radiotherapy group
For patients positive for driver gene mutations, first-line targeted therapy with or without chemotherapy is recommended according to NCCN guidelines. For patients negative for driver gene mutations, first-line immunotherapy combined with chemotherapy is recommended according to NCCN guidelines. Concurrent radiotherapy for the primary tumor in combination with drug therapy.
Intervention: Three-Dimensional Radiotherapy for Primary lungTumors (Radiation)
Outcomes
Primary Outcomes
Overall Survival, Local regional progressive-free survival, LRPFS
Time Frame: From enrollment to the end of treatment at 1 year
OS refers to the period the date of randomization in a clinical trial until the patient dies from any cause. Local progression-free survival time refers to the duration from randomization until the first occurrence of local progression at the primary tumor site or region, or death from any cause
Secondary Outcomes
- ORR,(From enrollment to the end of treatment at 1year.)
- PFS(From enrollment to the end of treatment at 1 year)
- Toxicities(From enrollment to the end of treatment at 1 year)
