Recent Advances in Nanodrug Delivery System for Tumor Combination Treatment Based on Photothermal Therapy

Although photothermal therapy (PTT) can act on tumors alone, resulting in tumor shrinkage or even eradication, this effect is short-lived, and the tumor may regrow. Thus, the most helpful contribution of PTT to cancer therapy is to employ it in conjunction with other tumor therapies, such as chemotherapy, immunotherapy, photodynamic therapy, gene therapy, radiotherapy therapy, and multiple combination therapy to boost treatment efficacy. This paper covers the benefits and drawbacks of combining photothermal therapy with various therapeutic approaches by the nanodrug delivery system and the possibilities and obstacles of clinical combination therapy.
