ABSTRACT
Poor clinical efficacy associated with postoperative hepatocellular carcinoma (HCC) often results from recurrence and metastasis. Hence, research has focused on establishing an effective multimodal therapy. However, complex combinations of active ingredients require multiple functions in therapeutic systems. Herein, a portable nanofiber patch composing germanium phosphorus (GeP) and anlotinib (AL) was designed to form a versatile platform for molecularly targeted photothermal-immune checkpoint blockade (ICB) trimodal combination therapy. The patches possess hydrophilic, satisfactory mechanical, and excellent photothermal conversion properties. Moreover, they achieve a penetrating and sustained drug release. The near-infrared light-assisted GeP-induced temperature increase regulates AL release, downregulating the expression of vascular-related factor receptors, triggering immunogenic cell death of tumor cells, and inducing dendritic cell maturation. Simultaneously, ICB therapy (programmed cell death ligand 1, PD-L1) was introduced to improve treatment outcomes. Notably, this trimodal combination therapy significantly inhibits vascular hypergrowth, enhances effector T-cell infiltration, and sensitizes the PD-L1 antibody response, boosting immunotherapy to suppress residual HCC recurrence and metastasis. Further validation of the genome sequencing results revealed cell pathways related primarily to regulatory immune effects. This study demonstrates the use of an effective and practical nanofiber patch to improve multimodal therapy of postoperative HCC, with high clinical translation value.
