The goal of this observational study is to evaluate the effectiveness and safety of Iparomlimab and Tuvonralimab (QL1706)-based therapy in patients with recurrent or metastatic cervical cancer who have experienced disease progression after platinum-based treatment.
The main questions it aims to answer are:
* Does QL1706-based therapy improve clinical outcomes compared with investigator-selected chemotherapy in patients with recurrent or metastatic cervical cancer?
* Does the addition of bevacizumab further improve treatment effectiveness?
* Which patient subgroups are most likely to benefit from QL1706-based therapy? Participants receiving QL1706-based therapy or investigator-selected chemotherapy as part of routine clinical practice will be followed through real-world clinical data collection. Using a target trial emulation framework, the study will compare treatment effectiveness and safety between groups. Clinical characteristics, treatment outcomes, and adverse events will be collected for analysis. In addition, artificial intelligence-based models and multi-omics analyses will be used to identify predictive biomarkers and explore potential mechanisms of treatment response and resistance.
