SBRT Combined With Chemotherapy and Tislelizumab in Metastatic NPC
Study Details
Study Description
Brief Summary
Radiotherapy and immunotherapy have achieved good survival benefit in advanced nasopharyngeal carcinoma. A number of clinical studies of immunotherapy combined with radiotherapy for nasopharyngeal carcinoma are also ongoing. This study preliminarily explored the efficacy and safety of SBRT combined with tislelizumab and chemotherapy in metastatic nasopharyngeal carcinoma. Hypofractionated radiotherapy combine with systemic chemotherapy and immunotherapy in advanced nasopharyngeal carcinoma. Not only it can achieve rapid response of distant metastases, but also to achieve long-term survival benefit for patients, which provides the reference for subsequent studies.

| Arm | Intervention/Treatment |
|---|---|
| Experimental: Experimental SBRT: Metastases were treated with SBRT, GTV 45Gy/3F/3d, each course of radiotherapy only treated metastases within 1 organ. Chemotherapy(GP or TP) was combined with tislelizumab for 4-6 cycles and tislelizumab was maintained until 2 years or disease progression or intolerable toxicity or death. Maintain: (1) For newly diagnosed metastatic patients, nasopharyngeal and metastatic lymph node irradiation was started 4 weeks after systemic therapy, using IMRT technique, only radiating the GTV of the nasopharyngeal and cervical region, DT 66 Gy/30 F/6 weeks was recommended. Tislelizumab was continued during radiotherapy and tislelizumab was used during maintenance. |
Radiation: SBRT
SBRT was added to systematic treatment (chemo+ PD-1 antibody)
