RESUMO
Osteosarcoma (OS) is the most common primary malignant bone tumor in clinic. It has high mortality and disability rate. Effective neoadjuvant chemotherapy combined with limb salvage surgery can improve the 5-year survival rate of OS patients. Drug resistance or low sensitivity of tumor cells is the most common cause of postoperative local recurrence and metastasis. Therefore, the sensitivity of OS cells to chemotherapy drugs is of great value to the prognosis of the patients. In recent years, traditional Chinese medicine has been widely used because of high efficiency and low toxicity. A large number of studies have confirmed that part of traditional Chinese medicine can reverse the chemotherapy resistance of OS cells by regulating the ABC transmembrane transport protein system. This article gives an overview of its related mechanisms and latest developments.
