Design outcomes

Secondary

MeasureTime frame
Secondary end point(s): Events free survival in patient with ABCB1/P-glycoprotein over-expression, and who do not over-express ABCB1/P-glycoprotein.;Timepoint(s) of evaluation of this end point: The events free survival will be evaluated by means of interim analysis after 2 and 3 years from the start of study. A further evaluation will be performed at the end of enrollment and after 2 years form the last enrolled patient.

Primary

MeasureTime frame
Main Objective: To assess the survival in patient with non metastatic osteosarcoma of the extremities treated with different chemotherapy protocols, according to the expression of ABCB1/P-glycoprotein;Primary end point(s): Overall survival;Timepoint(s) of evaluation of this end point: The overall survival will be evaluated at the end of study period (5 enrollment years and 2 years miminum follow-up from the last enrolled patient);Secondary Objective: To assess the survival in patient who over express ABCB1/P-glycoprotein, with chemotherapy protocol based on all the 5 available active drugs (Methotrexate, cisplatinum, doxorubicine, ifosfamide and mifamurtide) To assess the survival in patient who do not over express ABCB1/P-glycoprotein, treated with a 3-drugs regimen (methotrexate, cisplatinum and doxorubicine)
