Curcumin in Treatment of Osteosarcoma： A Review / 中国实验方剂学杂志

ABSTRACT

Osteosarcoma （OS） is the most common primary malignant bone tumor originating from mesenchymal stem cells， which features high degree of malignancy， strong invasiveness， easy early metastasis， and high recurrence rate. The clinical manifestations of OS are pain， local mass， limited movement， and pathological fracture. OS mainly occurs in children， adolescents， and the elderly， seriously threatening physical and mental health of patients， as well as their quality of life. The currently available therapies for OS are surgery， chemoradiotherapy， and the combination of the two. Although the therapeutic effect has been improved， tumor recurrence and metastasis and multidrug resistance still occur. Thus， the therapeutic effect is not satisfactory， especially in improving the overall survival rate of patients with metastatic OS. As a result， clinicians and researchers have been making efforts to find an effective therapy. In recent years， the mechanism of curcumin （CUR） against OS has attracted wide attention. CUR， a pigment extracted from the rhizomes or tubers of many plants， such as Curcuma longa， C. rcenyujin， and C. phaeocaulis， has a variety of pharmacological effects. Scholars have found that CUR has the effects of inhibiting proliferation， inducing apoptosis， and reversing multidrug resistance （MDR） of tumor cells， but also it has poor water solubility and low bioavailability， which limit the clinical application. This paper mainly discusses the mechanism of CUR against OS， the existing problems， new treatment methods， and future research directions， which is expected to provide new ideas for scientific researchers and provide a reference for the development and utilization of CUR in the future.
