Countermeasures and Mechanisms of Drug Resistance in Immunotherapy for Cervical Cancer

Cervical cancer has become a serious threat to women's health worldwide, advanced cervical cancer has limited treatment options. 5-year survival rate is less than 20%, which is a huge challenge for the gynecologic oncology community. Immunotherapy is one of the important treatment for patients with advanced cervical cancer. including immune checkpoint inhibitors, therapeutic vaccines, and periprocedural T-cell immunotherapy, etc. However, immunotherapy resistance makes some patients non-responsive and ineffective. Therefore, there is an urgent need to study and explore the mechanism of immune resistance to improve drug resistance. The present review summarizes the relevant studies on the mechanism of immune resistance in cervical cancer in recent years, mainly divided into factors such as intrinsic tumor and altered external immune environment, and introduces the countermeasures and progresses proposed for immune resistance.
