Inclusion criteria

Inclusion criteria: 1.Baseline Disease (1) Patients with newly diagnosed non-small cell lung cancer (NSCLC) complicated by malignant pleural effusion, confirmed by pathology.(2) Pleural effusion volume >= 500 ml (moderate or above), confirmed by ultrasound or CT as free fluid (non-encapsulated). (2) Diagnostic criteria for malignant pleural effusion:Pleural effusion confirmed as malignant by pathological examination, or meeting the following clinical criteria:1) Lung cancer already diagnosed, with no other explanation for the source of pleural effusion;2) Lung cancer with pleural effusion, and imaging findings (CT, PET-CT, MRI, or ultrasound) showing pleural nodules, masses, or irregular thickening consistent with pleural metastasis. 2.Clinical Characteristics(1) Age 18–75 years, ECOG performance status 0–2, expected survival >= 3 months.(2) No prior systemic therapy for the current lung cancer (including chemotherapy, immunotherapy, targeted therapy, or PDT) and no prior local therapy (such as pleurodesis or chest tube drainage). 3. Laboratory Parameters(1) Hematological function: Neutrophils >= 1.5 × 10^9/L, platelets >= 75 × 10^9/L, hemoglobin >= 90 g/L.(2) Hepatic and renal function: ALT/AST = 50 ml/min. 4.Group Matching CriteriaPD-L1 expression level testing (1% <= TPS < 50%), and exclusion of patients with confirmed driver gene mutations such as EGFR, ALK, or ROS1. 5.Informed ConsentPatients and their families sign the informed consent form, voluntarily participate in the study, and cooperate with follow-up.

Exclusion criteria

Exclusion criteria: 1. Known hypersensitivity to photosensitizers or related drugs; 2. Severe pulmonary dysfunction with dyspnea and inability to lie on one side; 3. Extensive pleural adhesions; 4. Comorbid severe diseases, including severe heart disease, cerebrovascular disease, uncontrolled diabetes, and uncontrolled hypertension; 5. Cachectic state; 6. Active bleeding or hemorrhagic diathesis (abnormal coagulation mechanism or prothrombin time below 40%); 7. Pregnant or lactating women; 8. Expected survival time less than 3 months; 9. Paraneoplastic or tumor-related pleural effusions without tumor cells in the pleural fluid, caused indirectly by non-tumor factors such as mediastinal tumor infiltration, bronchial obstruction, radiotherapy, pulmonary infarction, and superior vena cava syndrome; 10. Previous local pleural therapy (such as pleurodesis); 11. Psychiatric illness or poor compliance, preventing completion of the treatment plan and follow-up.
