Cervical cancer constitutes a significant health burden for women globally. While most patients with early-stage disease can be cured with radical surgery or chemoradiotherapy, patients with high-risk locally advanced disease or with recurrent/metastatic disease have a poor prognosis with standard treatments. Immunotherapies are a rational treatment for this HPV-driven cancer that commonly expresses programmed cell death ligand-1. Toripalimab, a humanized immunoglobulin G4 monoclonal antibody against PD-1, showed promising anti-tumor efficacy in multiple solid tumors. This randomised study is evaluating toripalimab combined with CCRT versus CCRT alone for treatment-naïve LACC.
