Nanoparticle-based drug delivery systems: opportunities and challenges in the treatment of esophageal squamous cell carcinoma (ESCC)

Esophageal squamous cell carcinoma (ESCC) is an aggressive malignancy characterized by limited treatment options and poor prognosis. Nanoparticle-based drug delivery systems have emerged as a promising strategy to enhance cancer therapy efficacy by improving drug targeting, reducing toxicity, and enabling multifunctional applications. This review highlights some key types of nanoparticles, including liposomes, polymeric nanoparticles, metallic nanoparticles, dendrimers, and quantum dots, which could effectively improve the delivery of various drugs used in chemotherapy, radiotherapy, and immunotherapy, offering more precise and effective treatment options. With the ability to improve drug stability and overcome biological barriers, nanoparticle-based systems represent a transformative strategy for ESCC treatment. Despite some challenges, such as biocompatibility and scalability, the future of nanoparticle-based drug delivery holds great promise, particularly in the development of personalized nanomedicine and novel therapeutic approaches targeting the tumor microenvironment. With ongoing advancements, nanoparticle-based drug delivery systems hold immense potential to revolutionize ESCC treatment and improve patient outcomes.
