RC48 Combined With Tislelizumab for Second-line Treatment of HER2 Expression in Recurrent Cervical Cancer

Summary

There is currently no standardized treatment for patients who have undergone first-line standard treatment. In this study, We investigated the efficacy and safty of RC48 combined with Tislelizumab in the second-line treatment of patients with HER2 expression in recurrent cervical cancer.
