简要总结
Patients with stage III non-small-cell lung cancer initially evaluated as unresectable are selected for the program, who are remained unresectable after 2-4 cycles of conversion chemotherapy combined with immune checkpoint inhibitors. Investigators will stratify the treatment according to different performance status scores and radiotherapy plan bi-lung receptor volume to evaluate the safety and efficacy of immunotherapy followed by combined radiotherapy.
详细描述
This is a prospective, real-world cohort study, which aimed to evaluate the safety and efficacy of immunotherapy followed by combined radiotherapy. Participants will be selected and entered into three different cohorts according to different performance status(PS) scores and radiotherapy schedules based on the amount of bilateral lungs treated. Cohort A: PS=0-1 and bilateral lung V20≤20%, mean lung dose(MLD)≤11 gray(Gy), radiotherapy and immunotherapy, followed by immunotherapy for up to 1 year; Cohort B: PS=0-1 and 20%<bilateral lung V20≤25% or 11 Gy<MLD≤13 Gy, radiotherapy combined with immunotherapy, followed by immunotherapy for up to 1 year; Cohort C: PS=2 or 25%<bilateral V20≤30% and 3 Gy <MLD≤ 17 Gy, radiotherapy alone, followed by immunotherapy for up to 1 year.

研究组 & 干预措施
Cohort A: concurrent chemoradiotherapy combined with ICIs
For performance status (PS)=0-1 and both lungs V20≤20%, mean lung dose (MLD)≤11 gray(Gy), then the patient should be treated with concurrent chemo-radiotherapy and immunotherapy, and immunotherapy should be given after chemo-radiotherapy to maintain up to 1 year. Participants eligible for enrollment will receive radiotherapy within 8 weeks of the end of chemotherapy combined with Immune checkpoint inhibitors (ICIs) at a radical prescribed dose of 60 Gy ± 10% at 2 Gy once daily for 5 days per week. The chemotherapy regimen will be cisplatin at a dose of 25 mg/m2 once a week for 5-6 cycles. Marketed programmed cell death 1 (PD-1) or programmed cell death L1 (PD-L1) inhibitors are chosen as immunotherapy agents. Immunotherapy will be given every 3 weeks, with no more than 3 cycles of immunotherapy during radiotherapy. The dosage is recommended according to the drug insert.
