Research Advances and Therapeutic Strategies of Human Osteosarcoma

Dear Colleagues,

Osteosarcoma is the most frequent pediatric primary bone tumor. Current treatments that combine conventional chemotherapies and surgery have enabled to reach a five-year remission rate higher than 70%. However, this rate dramatically decreases below 30% if metastases are observed at the time of diagnosis or if the tumor is resistant to chemotherapy. In the last decade, besides researches on new therapeutic targets to eradicate the tumor cells (epigenetic, genetic, or metabolic targets), many studies have been devoted to a better understanding of both metastatic and resistance processes in order to be able, in a near future, to block or reverse them. These studies have mainly focused on the tumor microenvironment and on tumor cell heterogeneity in those two processes.

This Special Issue will discuss recent developments in our understanding of osteosarcoma metastatic and resistance processes and delineate future therapies based on the blockage of these two deleterious processes.
