The
brain tumor is a kind of malignant
tumor with brutal treatment, high recurrence rate, and poor prognosis, and the incidence and death rate is increasing yearly. Surgery is often used to remove the primary
tumor, supplemented by
radiotherapy and
chemotherapy, which have highly toxic side effects. Therefore, there is an urgent need to explore new strategies, methods, and technologies that can genuinely improve the treatment of
brain tumors. Ferroptosis differs from traditional apoptosis's morphological and biochemical characteristics, and ferroptosis possesses its unique characteristics and mechanisms, opening up a new field of ferroptosis treatment for
cancer. It has been found that there is a close relationship between ferroptosis and
brain tumors, and a novel
nano-drug delivery system based on ferroptosis has been used for the ferroptosis treatment of
brain tumors with remarkable effects. This review firstly analyzes the characteristics of ferroptosis, summarizes the mechanism of its occurrence and some factors that can be involved in the regulation of ferroptosis, introduces the potential link between ferroptosis and
brain tumors, and clarifies the feasibility of ferroptosis in the treatment of
brain tumors. It then presents the ferroptosis
nano drug delivery systems developed under different metabolic pathways for ferroptosis treatment of
brain tumors. Finally, it summarizes the current problems and solutions of ferroptosis nano drugs for
brain tumor treatment, aiming to provide a reference for developing ferroptosis nano drugs against
brain tumors.
