Cervical cancer is one of the most common malignancies globally, particularly
prevalent in low- and middle-income countries, and is the second most prevalent
cancer-related cause of death. Despite the improvement in screening and preventive
efficacy of the HPV vaccines, the majority of these cancers are diagnosed at a late
stage where traditional therapies like chemotherapy and radiotherapy are of
minimal benefit with disappointing long-term survival. In the past few years,
immunotherapy has emerged as a breakthrough approach in oncology, offering
new treatment options for recurrent or advanced cervical cancer. This narrative
review discusses the current place and future directions of immunotherapy in
advanced cervical cancer. The review addresses key mechanisms of tumor immune
escape including HPV-mediated expression of viral oncoproteins E6 and E7, PD-L1
overexpression, and the immunosuppressive tumor microenvironment. The review
criticizes several immunotherapeutic modalities such as immune checkpoint
inhibitors (e.g., pembrolizumab, nivolumab), adoptive cell therapies (CAR-T, TILs),
therapeutic vaccines, and monoclonal antibodies. Furthermore, it highlights the
rationale and clinical benefit of combining immunotherapy with chemotherapy,
radiotherapy, and targeted agents such as bevacizumab, as in trials such as
KEYNOTE-826. While immunotherapy is a paradigm change in the treatment of
cervical cancer, there are challenges. These are lack of access, cost of therapy,
immune resistance, and need for predictive biomarkers. These limitations will be
overcome by research and global health policy to make immunotherapy a just and
effective option for all patients with cervical cancer.
