Plain-language summary
The purpose of this phase Ⅱ trial was to investigate the effect of low-dose radiotherapy (LDRT) on the tumor immune microenvironment (TME) in oligometastasis, oligoprogression, and oligopersistence of non-small cell lung cancer (NSCLC) after immunotherapy. At least 20 participants will be enrolled in this study. All will take part at Hetian District People's Hospital.

. Patients with histologically or cytologically confirmed NSCLC.
. Patient developed oligometastasis, oligoprogression or oligopersistence after standard immunotherapy.
. Be ≥18 years of age on day of signing informed consent.

. Patients who have failed the standard therapy, or who are unsuitable for standard treatment, or refuse chemotherapy.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. At least one measurable lesion according to RECIST 1.1. A lesion that has previously received radiotherapy can be considered a target lesion only if this lesion is clearly progressed after radiotherapy.
. The target lesions (irradiated lesions) are \> 5cm in in diameter
Exclusion criteria
. Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis and/or spinal cord compression, etc.
. With oncologic emergencies that require immediate treatment
. EGFR/ALK/ROS-1 mutation or mutation status unknown.
. Has evidence of interstitial lung disease or active and/or non-infectious pneumonitis (drug-induced pneumonia, radiation-induced pneumonia, etc.) requiring steroid therapy.
. History of pulmonary fibrosis, pulmonary hypertension, severe irreversible airway obstruction disease
. Patients with peripheral neuropathy.
. Significant heart disease or impairment of cardiac function
. Fluid accumulating in the third space, such as pericardial effusion, pleural effusion and peritoneal effusion that remains uncontrolled by aspiration or other treatment
