摘要: Osteosarcoma (OS), the most common malignant tumor of bone, is presently treated with multidrug neoadjuvant chemotherapy protocols, which allow to cure 60-65% patients but also induce toxicity events that cannot be predicted or efficiently prevented. The identification and validation pharmacogenomic biomarkers is, therefore, absolutely warranted provide bases for planning personalized treatments aim increase therapeutic benefits avoid limit unnecessary toxicities. As several targeted therapies against molecular immunological markers in OS are under clinical investigation, it may speculated some new agents innovative emerge next years. However, real improvement perspectives strictly connected stratify responders non-responders identify those individuals higher susceptibility treatment-associated toxicity. This review provides an overview identified so far OS, appear promising candidates a translation practice, after further investigation and/or prospective validation.
