Pembrolizumab and Chemotherapy in Cervical Cancer: A New Standard of Care?

Cervical cancer (CC) still has a high incidence despite screening programmes and access to human papillomavirus (HPV) vaccination, with a poor prognosis in the advanced setting. Most cases of cervical carcinoma are related to HPV infection. The pathogen-induced nature of the disease, the involvement of genes regulating the immune response and the high grade of immune infiltration provide the rationale to evaluate anti-programmed death-(ligand)1 (PD-[L]1) immune checkpoint inhibitors in CC. This article reviews the promising outcomes of the KEYNOTE-826 phase III trial, which evaluates the addition of pembrolizumab to chemotherapy in patients with PD-L1-positive disease and recurrent, persistent or metastatic cancer of the cervix, leading to an improvement of progression-free survival and overall survival. We also aim to address some outstanding questions and discuss the next steps in immunotherapy for CC.
