Locally advanced cervical cancer (stage IB3, IIA2) patients with postoperative risk factors need better treatment. We initiated a clinical study to explore the effectiveness of adjuvant chemoradiotherapy followed by Zimberelimab for these patients.

For cervical cancer, although clinical research on PD-1 monoclonal antibodies was launched relatively late, the research results so far show that PD-1 monoclonal antibodies combined with chemotherapy have a high clinical effectiveness and a relatively high efficacy in the treatment of advanced/recurrent cervical cancer. Good security. However, there is currently a lack of clinical evidence for the use of PD-1 monoclonal antibodies combined with chemoradiotherapy in the treatment of high-risk patients after cervical cancer surgery. Therefore, this study intends to explore the clinical efficacy of postoperative adjuvant radiochemotherapy followed by PD-1 monoclonal antibody in the treatment of high-risk patients with locally advanced (IB3, IIA2) cervical cancer after surgery, and provide a new solution for clinical treatment.
