Multipoint Costriking Nanodevice Eliminates Primary Tumor Cells and Associated‐Circulating Tumor Cells for Enhancing Metastasis Inhibition and Therapeutic Effect on HCC
Eliminating primary tumor (“roots”) and inhibiting associated‐circulating tumor cells (associated‐CTCs, “seeds”) are vital issues that need to be urgently addressed in cancer therapy. Associated‐CTCs, which include single CTCs, CTC clusters, and CTC–neutrophil clusters, are essential executors in metastasis and the cause of metastasis‐related death in cancer patients. Herein, a “roots and seeds” multipoint costriking nanodevice (GV‐Lipo/sorafenib (SF)/digitoxin (DT)) is developed to eliminate primary tumors and inhibit the spread of associated‐CTCs for enhancing metastasis inhibition and the therapeutic effect on hepatocellular carcinoma (HCC). GV‐Lipo/SF/DT eliminates primary tumor cells by the action of SF, thus reducing CTC production at the roots and improving the therapeutic effect on HCC. GV‐Lipo/SF/DT inhibits associated‐CTCs effectively via the enhanced identification and capture effects of glypican‐3 and/or vascular cell adhesion molecule 1 (VCAM1) targeting, dissociating CTC clusters using DT, blocking the formation of CTC–neutrophil clusters using anti‐VCAM1 monoclonal antibody, and killing CTCs with SF. It is successfully verified that GV‐Lipo/SF/DT increases the CTC elimination efficiency in vivo, thus effectively preventing metastasis, and shows enhanced antitumor efficacy in both an H22‐bearing tumor model and orthotopic HCC models. Overall, the “roots and seeds” multipoint costriking strategy may open a new cancer treatment model for the clinic.
