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.
Interventions
The experimental group received radical radiotherapy for the primary lung lesion in combination with first-line drug therapy recommended by the NCCN guidelines.

Eligibility
Inclusion criteria

Age 18-80 years, ECOG 0-2 or KPS ≥70; no contraindications to radiotherapy, EGFR-TKI, ALK/ROS1 inhibitors, chemotherapy, or immunotherapy; 5. No major organ dysfunction, or laboratory test results must meet the following criteria: Hematology , cardiac function, liver function , and renal function within normal ranges according to respective laboratory standards. Pulmonary function : FEV1 \>50%, mild to moderate impairment of lung function. 6.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Overall Survival, Local regional progressive-free survival, LRPFS | 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
| Measure | Time frame | Description |
|---|---|---|
| ORR, | From enrollment to the end of treatment at 1year. | ORR define the objective response rate according to RECIST version 1.1. |
| PFS | From enrollment to the end of treatment at 1 year | PFS, definehe length of time during and after treatment that a patient lives with the disease but it does not get worse. It is typically measured from the start of treatment until disease progression or death from any cause. |
| Toxicities | From enrollment to the end of treatment at 1 year | Toxicities: The primary assessment of radiotherapy-related toxicities is based on the CTC 5.0 criteria, focusing on treatment-related toxicities such as radiation pneumonitis, radiation esophagitis, bone marrow suppression, and hematologic toxicities affecting the liver and kidneys. And the time without cancer worsening or death |
