Detailed Description
The study evaluated the effectiveness, safety and immune effects of dose-painting radiation in patients with locally advanced non-small cell lung cancer.
The primary endpoint is PFS. Secondary points contains ORR, OS, HRQoL, and safety.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Assigned Interventions Radiation therapy: Dose-painting radiation Systemic treatment: Choose a systemic treatment plan according to the patient's genetic testing status (1) Chemotherapy Squamous cell carcinoma: Paclitaxel 135mg/m2 D1 + Cisplatin 25mg/m2 D1-3, every 21 days, a total of 2-4 cycles. Non-squamous cell carcinoma (adenocarcinoma, large cell carcinoma): Pemetrexed 500mg/m2 d1 + Cisplatin 75 mg/m2 d1-3, a total of 2-4 cycles. (2) Targeted therapy: According to the patient's genetic testing status, molecular targeted therapy such as EGFR-TKI and ALK inhibitors can be selected; (3) Immunotherapy: According to the patient's genetic testing status, immunotherapy such as PD1/PD-L1 inhibitors can be selected; |
Radiation: Dose-Painting Radiation
Radiation therapy:
Delineation of target area:
The primary tumor is delineated into different target areas according to the anatomical position of the tumor, including the central area tumor GTV-Tcentral and GTV-Tperipheral.
Exposure dose:
1) GTV-Tcentral: 2.0～2.5Gy/f, bid, 10-13d, physical dose 40-65Gy 2) GTV-Tperipheral: 3.0～4.0Gy/f, bid, 10-13d, physical dose 60-104Gy 3) GTV-N (mediastinal lymph node): 2.0Gy/f, bid, 10-13d, physical dose 40-52Gy

Outcome Measures
Primary Outcome Measures
- FPS [up to 3 years]
progression-free survival (PFS) refers to the time from enrollment to the first recording of disease progression as determined by RECISTv1.1, or to death due to any cause (whichever occurs first). PFS will be analyzed in the ITT analysis set.
Secondary Outcome Measures
- ORR [up to 3 years]
Objective response rate, according to RECISTv1.1, the proportion of patients with CR or PR was determined. If the patient has not undergone a post-baseline assessment, it is considered unremission
- OS [up to 3 years]
OS(Overall survival) refers to the time from enrollment to the first recorded death due to any cause (whichever occurs first).
- HRQoL [up to 3 years]
HRQoL uses EORTCQLQ-C30 to assess the overall health of patients. The post-baseline score of the treatment group was studied, and the score changes from the baseline were summarized descriptively.
Other Outcome Measures
- Prognostic Biomarkers [up to 8 weeks]
The expression of lymphocyte subsets in peripheral blood, including CD3+ T cells, CD4+ T cells, CD8+ T cells, CD8+CD28+ T cells, CD8+CD28- T cells, Treg cells, NK cells, NKT cells, γδ T cells;
- Prognostic Biomarkers [up to 8 weeks]
The changing trend of various cytokines in radiotherapy, including IL-6, IL-1b, IL-9, TNF-a, TGF-β, IL-10, IL-21, etc.
