PD-1 Blockade and Bevacizumab Replace Cisplatin in Locoregionally Advanced Nasopharyngeal Carcinoma

18. April 2022 aktualisiert von: Ming-Yuan Chen, Sun Yat-sen University

PD-1 Inhibitor and Bevacizumab Replace Cisplatin in Induction, Concurrent, and/or Adjuvant Therapy for High-risk Locoregionally Advanced Nasopharyngeal Carcinoma.

At present, the treatment regimen of locally advanced nasopharyngeal carcinoma still needs to be further improved, and the focus of improvement lies in "replacing cisplatin with high-efficiency and low-toxicity treatment regimen". Considering the synergistic effect among radiotherapy, immunotherapy and anti-angiogenesis therapy, we chose PD-1 inhibitor combined with bevacizumab to replace cisplatin chemotherapy.

Studienübersicht

Detaillierte Beschreibung

We plan to use PD-1 inhibitor combined with bevacizumab to replace cisplatin (induction + concurrent ± adjuvant) in patients with locally advanced nasopharyngeal carcinoma. Considering the safety of the original study, we will set up two groups for the adjuvant treatment stage: one group will only use PD-1 inhibitor at the adjuvant treatment stage (low risk group), and the other group will use bevacizumab +PD-1 inhibitor combined treatment (high risk group). Once the efficacy and safety of this protocol are confirmed, it may provide a new treatment option for locally advanced nasopharyngeal carcinoma.
