Introduction Cadonilimab provides substantial clinical benefits in recurrent or metastatic cervical cancer (R/M CC) in several clinical trials and meeting abstracts. However, the efficacy of cadonilimab in patients with prior failure of anti- programmed death receptor-1 (PD-1) inhibitors, as well as a direct comparison of its efficacy and safety with anti-PD-1 inhibitors, has not been reported in real-world settings. Methods We conducted a retrospective study at our hospital, including two R/M CC patient cohorts. The first cohort consisted of 101 patients who received cadonilimab, either as monotherapy or in combination with other therapies, between July 1, 2022, and October 31, 2024. The second cohort comprised 201 patients who were treated with anti-PD-1 inhibitors (alone or in combination) but did not receive cadonilimab, between August 1, 2018, and March 31, 2024. In cadonilimab group, 4 patients received monotherapy, 13 patients received radiotherapy or surgery, 72 patients received concurrent chemotherapy, 57 patients received targeted therapy. Among anti-PD-1 group, 6 patients received monotherapy, 34 patients received radiotherapy or surgery, 127 patients received concurrent chemotherapy, 116 patients received targeted therapy. Clinicopathologic information, peripheral blood markers and treatment regimens were collected and analyzed to identify prognostic factors of cadonilimab through response rate comparison, as well as univariate, and multivariate analyses.
