Overview

This study aims to evaluate the efficacy and safety of Tislelizumab combined with concurrent chemoradiotherapy in the treatment of cervical cancer patients with cervical mass > 4cm and regional lymph node metastasis, paracervical invasion and regional lymph node metastasis, stage IIIA, stage IIIB, and stage IVA. To provide a clinical reference for finding a safe and effective individualized treatment plan to improve the survival prognosis of locally advanced cervical cancer patients.
