Abstract:
Great improvement has been made in the 5-year survival of patients with osteosarcoma due to application of novel chemo-agent and progression in surgical techniques. However, the treatment outcome of osteosarcoma was bottlenecked by drug resistance and immuno-escape mechanism. Recent studies showed that some osteosarcoma cells possess the characteristic of tumor stem cells: capable of self-renewal and extensive proliferation. Meanwhile, SP cells, isolated from osteosarcoma cells, have high expression of ABCG2 and can form tumor in NOD/SCID mice, indicating that the drug resistance of osteosarcoma cells might be related to SP cells. Studies on the biomarkers of tumor stem cells and decrease of ABCG2 expression may contribute to the treatment outcome of osteosarcoma. Moreover, research on active and passive immunotherapy and Src protein tyrosine-kinase targeted therapy may provide new pathways for treatment of osteosarcoma.
