INTRODUCTION: Gestational trophoblastic neoplasia (GTN) is a highly curable malignancy arising from placental trophoblasts, yet a small subset of patients develops multidrug resistance with limited therapeutic options. The discovery of high programmed death-ligand 1 (PD-L1) expression across trophoblastic tumors has provided a compelling biological rationale for immunotherapy, particularly immune checkpoint blockade targeting the PD-1/PD-L1 axis.
OBJECTIVE: To summarize current evidence on immunotherapy in GTN, integrating biological foundations, clinical experiences, and ongoing clinical trials, and to discuss future perspectives toward individualized, fertility-preserving management.
METHODS: A narrative review was conducted according to structured PRISMA-based principles. Literature was retrieved from PubMed, Scopus, and Web of Science from 2000 to 2025 using predefined descriptors related to GTN and immunotherapy. Eligible studies included clinical trials, case series, case reports, and translational research addressing immune checkpoint inhibitors in GTN.
RESULTS: GTN exhibits high PD-L1 expression, mirroring the immune-privileged nature of the placenta. Checkpoint inhibitors alone, such as pembrolizumab, avelumab, or the combination of camrelizumab plus apatinib (that potently suppresses the kinase activity of vascular endothelial growth factor 2), have demonstrated complete and durable responses in approximately 70-80% of patients with multidrug-resistant GTN, with acceptable safety and preserved fertility.
CONCLUSIONS: Immunotherapy has expanded therapeutic GTN, transforming refractory disease as a result of its immune responsiveness. Checkpoint inhibition not only achieves high remission rates but also offers fertility preservation and long-term survivorship. The future challenge lies in optimizing combination strategies, refining biomarkers, and ensuring equitable global access to these emerging treatments.
