Abstract:
Background: Immunotherapy for cancer includes Chimeric Antigen Receptor (CAR)-T
cells, CAR-natural Killer (NK) cells, PD1, and the PD-L1 inhibitor. However, the proportion of
patients who respond to cancer immunotherapy is not satisfactory. Concurrently, nanotechnology
has experienced a revolution in cancer diagnosis and therapy. There are few clinically approved
nanoparticles that can selectively bind and target cancer cells and incorporate molecules, although
many therapeutic nanocarriers have been approved for clinical use. There are no systematic reviews
outlining how nanomedicine and immunotherapy are used in combination to treat cancer.
Objective: This review aims to illustrate how nanomedicine and immunotherapy can be used for
cancer treatment to overcome the limitations of the low proportion of patients who respond to cancer
immunotherapy and the rarity of nanomaterials in clinical use.
Methods: A literature review of MEDLINE, PubMed / PubMed Central, and Google Scholar was
performed. We performed a structured search of literature reviews on nanoparticle drug-delivery
systems, which included photodynamic therapy, photothermal therapy, photoacoustic therapy, and
immunotherapy for cancer. Moreover, we detailed the advantages and disadvantages of the various
nanoparticles incorporated with molecules to discuss the challenges and solutions associated with
cancer treatment.
Conclusion: This review identified the advantages and disadvantages associated with improving
health care and outcomes. The findings of this review confirmed the importance of nanomedicinecombined
immunotherapy for improving the efficacy of cancer treatment. It may become a new way
to develop novel cancer therapeutics using nanomaterials to achieve synergistic anticancer immunity.
