Adjuvant Chemoradiotherapy Followed by Zimberelimab for Locally Advanced Cervical Cancer.

Adjuvant Chemoradiotherapy Followed by Zimberelimab for Locally Advanced Cervical Cancer (IB3, IIA2) Patients

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.
