Advances in controlled release drug delivery systems based on nanomaterials in lung cancer therapy: A review

Lung cancer is one of the most common malignant tumors, with the highest morbidity and mortality rates. Currently, significant progress has been made in the treatment of lung cancer, which has effectively improved the overall prognosis of patients, but there are still many problems, such as tumor recurrence, drug resistance, and serious complications. With the rapid development of nanotechnology in the field of medicine, it breaks through the inherent limitations of traditional cancer treatments and shows great potential in tumor treatment. To address the drawbacks of traditional therapeutic means, nanodrug delivery systems can release drugs under specific conditions, thus realizing tumor-targeted drug delivery, which improves the antitumor effect of drugs. In this paper, we review the current treatments for lung cancer and further discuss the advantages and common carriers of nanodrug delivery systems. We also summarize the latest research progress of nanotargeted drug delivery systems in the field of lung cancer therapy, discuss the problems faced in their clinical translation, and look forward to future development opportunities and directions.
