Whole-target Consolidation Therapy Under Systemic Therapy for Oligometastatic Nasopharyngeal Carcinoma

Patients receive gemcitabine (1000 mg/m² d1,8), cisplatin (80mg/m² d1), and camrelizumab (200mg, iv drip for over 60min) every 3 weeks for 6 cycles before locoregional radiotherapy.

"IMRT: 5 fractions per week for 6 weeks to a total dose of 70 Gy and 33 fractions to the primary tumor.~SBRT: 3 months after locoregional IMRT, patients receive SBRT for all oligometastatic lesions as radical therapy to control the disease and reduce any potential adverse impact to living quality. The dosage is based on published clinical studies.~Camrelizumab (200mg, iv drip for over 60min) every 2 weeks began on the first day of IMRT until an intolerable toxicity, or disease progression, or withdrawal of consent, or the investigator determines that he or she has to withdraw from treatment, or has been treated for up to 2 years."
