  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Experimental arm
Patients received three cycles of neoadjuvant cadonilimab plus chemotherapy. Patients subsequently underwent radical hysterectomy with pelvic lymphadenectomy, with para-aortic lymph node biopsy/dissection performed when indicated. Postoperative adjuvant therapy was administered according to pathological findings.
