Efficacy and Safety of HGXJT in Bone Metastatic NSCLC Patients

Inclusion Criteria: 1. Patients with non-small cell lung cancer diagnosed by histopathology or cytopathology. 2. Presence of bone metastases. 3. EGFR/ALK gene wild type. 4. No prior treatment with PD-1 inhibitors (combination or monotherapy) 5. Those who have not received prior antitumor therapy or have not received further antitumor therapy after failure of first-line antitumor therapy. 6. PS score (ECOG) ≤ 2 points 7. Normal hepatic and renal function. Normal hepatic function: total serum bilirubin level ≤ 1.5 times of the upper limit of normal value(ULN), serum serum aspartate aminotransferase(AST) \& alanine aminotransferase(ALT) ≤ 2.5 times ULN Normal renal function: serum creatinine ≤ 1.5 mg/dl (133 μmol/L) and/or creatinine clearance ≥ 60 ml/min. 8. Presence of at least one assessable lesion. 9. Signed informed consent, patient willing to accept this regimen, able to adhere to the medication, and good compliance. Exclusion Criteria: 1. Unable to complete the baseline assessment form 2. Combination of other serious illnesses, including uncontrolled active infection, severe electrolyte disturbances, and significant bleeding tendencies. 3. Pregnant or lactating women. 4. Combined autoimmune diseases, hematologic disorders, or long-term use of hormones or immunosuppressive drugs. 5. Combination of other uncontrolled tumors. 6. Combination of severe brain or mental illness that affects the patient's ability to self-report. 7. Combined organ transplant history (including bone marrow autotransplantation and peripheral stem cell transplantation). 8. Those who are legally incompetent and whose medical or ethical reasons affect the continuation of the research.
