About

The purpose of this study is to explore the efficacy and tolerance of local consolidative radiotherapy combined with Camrelizumab and chemotherapy in patients with oligometastatic nasopharyngeal carcinoma

Full description

This trial was a single-arm, multicenter phase Ⅱ clinical study. Eligible oligometastatic NPC patients were scheduled to evaluate the efficacy and tolerance of local consolidative radiotherapy combined with camrelizumab and chemotherapy in patients with oligometastatic NPC. Progression-free survival (PFS) determined will be the primary outcome measures.

Ages: 18 to 70 years old
