Fighting metastasis is a major challenge in cancer therapy, and stimulation of the immune system is of particular importance in the treatment of metastatic cancers. Here, an integrated theranostic nanoplatform was developed for the efficient treatment of highly metastatic tumors. Versatile functions including “And” logically controlled drug release, prolonged circulation time, tumor targeting, and anti-metastasis were integrated into doxorubicin (DOX) loaded, highly integrated mesoporous silica nanoparticles (DOX@HIMSNs) for a systemic treatment of highly metastatic triple negative breast cancer (TNBC). It was found that the good therapeutic effect of DOX@HIMSN was only partially attributed to its anticancer cytotoxicity. Most importantly, DOX@HIMSN could induce anticancer immune responses including dendritic cell (DC) maturation and antitumor cytokine release. Compared with the traditional tumor chemotherapy, the integrated theranostic nanoplatform we developed not only improved the tumor specific cytotoxicity but also stimulated antitumor immune responses during the treatment.
