Advancing personalized medicine in LMICs: Predictive indicators for cervical cancer immunotherapy response

Abstract

The World Health Organization reports that cervical cancer ranks as the eighth most common cancer worldwide and is the ninth leading cause of cancer-related deaths. It is also the most prevalent cancer among women in 25 countries, primarily in Sub-Saharan Africa. Consequently, cervical cancer continues to pose a significant global health challenge, particularly due to the limited treatment options available for advanced stages of the disease. Evidently, immunotherapy is a promising strategy, but its efficacy is variable among patients. As such, predictive indicators are essential for identifying patients who are most likely to benefit from immunotherapy and for guiding treatment decisions. This review provides an overview of the current landscape of predictive biomarkers in cervical cancer immunotherapy, including immune checkpoint molecules, tumor mutational burden and immune cell infiltration. We further discuss additional factors such as cytokines, tumor infiltrating lymphocytes and previous exposure to platinum-based chemotherapy. As the field continues to evolve, ongoing research efforts are needed to refine predictive biomarkers and optimize patient selection in LMICs for immunotherapy in cervical cancer.
