About this trial
This is a phase II, single-arm study to evaluate the efficacy and safety of Serplulimab plus chemotherapy as conversion treatment in patients with stage IIIB-IVA oligometastatic non-small cell lung cancer.
Eligibility criteria
Qualifiers
Patients should voluntarily join this study and sign the informed consent form
NSCLC patients diagnosed by cytology or histology and not previously receiving anti-tumor treatments (including systemic treatments, local treatments .etc)
Patients with IIIB - IVA oligometastatic NSCLC : (a) IIIB - IIIC stage (T1-4N2-3): patients are not suitable or refuse to receive upfront surgical resection or radiotherapy; (b) oligometastatic stage IV (T1-3N0-2): radical resection/radiotherapy is feasible for metastatic lesions (the number of metastases being up to 3, and the maximum diameter of metastases being up to 2cm)
After evaluation by MDT, upfront surgical resection is not the preferred treatment, but after induction systemic treatments, radical resection of the primary tumor is feasible, and radical resection/radiotherapy is feasible for extrathoracic metastases (if any)
Disqualifiers
NSCLC patients have sensitive EGFR mutation, EML4-ALK fusion or other forms of ALK gene changes
Patients have previously received immune checkpoint inhibitors such as PD-1/ PD-L1/CTLA4 antibody
Patients with other primary malignancies within the past 3 years (excluding cured skin basal cell carcinoma and cervical carcinoma in situ)
Patients with active hepatitis B/C
