Review outlines polymer-based approaches to improve solid tumor immunotherapy
Solid tumors can block medicines and weaken the immune system’s attack on cancer.
A review describes tiny polymer-based carriers that could target several of these barriers at once.
Imaging tools could help track how tumors respond and guide treatment adjustments.
The approaches are promising, but more work is needed to address safety and large-scale manufacturing before they can be used widely.
A review published in the Chinese Journal of Polymer Science examines polymeric nanomedicine strategies for regulating the tumor microenvironment and supporting solid-tumor immunotherapy.
The review describes approaches targeting cellular, physical and biochemical barriers that can suppress immune responses or limit drug delivery.
Examples include nanomedicines designed to reprogram tumor-associated macrophages, reduce suppressor cells, inhibit regulatory T cells and inactivate cancer-associated fibroblasts.
The authors also discuss imaging methods, including near-infrared II fluorescence, ultrasound, MRI and urine-based reporters, to monitor immune activity and guide treatment.
The review identifies challenges to clinical translation, including carrier toxicity, accelerated blood clearance associated with PEGylation and variability in large-scale manufacturing.
