Brief Summary

Nasopharyngeal carcinoma is the most common malignant tumor of head and neck in southern China. After standard treatment, about 20% of the patients had local recurrence or distant metastasis, and the patients faced death in a short time. Currently, there is no recommended treatment for patients with recurrent or metastatic nasopharyngeal carcinoma who have unsatisfactory results of first-line chemotherapy and subsequent immunotherapy. Patients who have failed multiline therapy have a low survival rate and no drugs are available.This project aims to evaluate the efficacy and safety of sintilimab in combination with multimodal radiotherapy for patients with recurrent or metastatic nasopharyngeal carcinoma who have previously received immunotherapy and still progress after multiline therapy, and to seek a new therapeutic approach for such patients.

Study Arms (1)

Sintilimab in combination with Multimodality Radiotherapy group

EXPERIMENTAL

The dose of sintilimab was 200mg per dose, intravenously, once every 3 weeks. Multimodal radiotherapy methods: ①SBRT: ≥1 independent lesion was selected, with a single dose of 8-10Gy and a total dose of 40-60Gy, divided into 5-6 times of radiotherapy. The final frequency and total dose of radiotherapy were determined by the radiologist.② Low-dose radiotherapy: ≥1 independent lesion was selected, and the single dose, the final frequency of radiotherapy and the total dose were determined by the radiologist.

Drug: Sintilimab in combination with Multimodality Radiotherapy
