NCT04383288

Brief Summary

Post-authorization, observational, multicenter and prospective study in patients between 2 and 30 years old diagnosed with non-metastatic high-grade osteosarcoma of the extremities. All patients included in the study will receive the initial neoadjuvant treatment prescribed by the doctor of each center, according to standard practice (involving methotrexate, cisplatin, and adriamycin). This initial treatment precedes surgical treatment. After surgical treatment, the histological response to neoadjuvant chemotherapy will be evaluated. The histological response to primary chemotherapy will be expressed as a percentage of tumor necrosis. In the case of tumor necrosis above 90% the patient is defined as a "good responder" in case of a lower percentage as a "poor responder". As an adjuvant treatment, the following options may be given according to standard practice in each center:

  1. 1.\- If there is overexpression of ABCB1 / P-glycoprotein and poor response to induction treatment, in many sites ifosfamide at high doses and MTP-PE, is incorporated in addition to adriamycin.
  2. 2.\- If there is overexpression of ABCB1 / P-glycoprotein and a good response to induction treatment, in many centers the option of additional administration of methotrexate, CDDP and adriamycin will be chosen.
  3. 3.\- If there is no overexpression of ABCB1 / P-glycoprotein, the administration of methotrexate, adriamycin and cisplatin will be chosen in many sites.

Outcome Measures

Primary Outcomes (1)

  • Overall Survival

    The Overall Survival will be evaluated at the end of the study period (5 enrollment years and 2 years - minimum- follow-up from the last enrolled patient)

    The patients will be followed in term of Overall Survival, for all the study period (expected average: 7 years)

Secondary Outcomes (1)

  • Events free survival

    After 2 and 3 years from the start of study

Study Arms (3)

Overexpression of ABCB1 / P-glycoprotein. Poor response

If there is overexpression of ABCB1 / P-glycoprotein and poor response to induction treatment, in many sites ifosfamide at high doses and MTP-PE (Muramyl tripeptide phosphatidylethanolamine), is incorporated in addition to adriamycin. BEFORE SURGERY TREATMENT: Methotrexate: 12g/m2 (3 cycles) Cisplatinum: 120mg/m2 (3 cycles) Doxorubicin: ADM (Adriamycin) 75mg/m2 (3 cycles) AFTER SURGERY TREATMENT for poor responder patients with positive P-GLYCOPROTEIN Methotrexate 12g/m2; Cisplatinum 120mg/m2; Doxorubicin 90mg/m2 ifosfamide 15g/m2 MEPACT 2 mg/m2 twice a week for the first 3 months the weekly for the next 6 months (total length treatment 44 weeks) All the product are used as commercial formulation Other Names: Methotrexate Cisplatinum doxorubicin ifosfamide mifamurtide

Overexpression of ABCB1 / P-glycoprotein. Good response

If there is overexpression of ABCB1 / P-glycoprotein and a good response to induction treatment, in many centers the option of additional administration of methotrexate, CDDP (Cisplatinum) and adriamycin will be chosen. BEFORE SURGERY TREATMENT: Methotrexate: 12g/m2 (3 cycles) Cisplatinum: 120mg/m2 (3 cycles) Doxorubicin: ADM 75mg/m2 (3 cycles) AFTER SURGERY TREATMENT for good responder patients with positive P-GLYCOPROTEIN Methotrexate 12g/m2 (10 Cycles) Cisplatinum 120mg/m2; Doxorubicin 90mg/m2 MEPACT 2 mg/m2 twice a week for the first 3 months the weekly for the next 6 months (total length treatment 44 weeks) All the product are used as commercial formulation Other Names: Methotrexate Cisplatinum doxorubicin ifosfamide mifamurtide

No overexpression of ABCB1 / P-glycoprotein

If there is no overexpression of ABCB1 / P-glycoprotein, the administration of methotrexate, adriamycin and cisplatin will be chosen in many sites. BEFORE SURGERY TREATMENT: Methotrexate: 12g/m2 (3 cycles) Cisplatinum: 120mg/m2 (3 cycles) Doxorubicin: ADM 75mg/m2 (3 cycles) AFTER SURGERY TREATMENT: Methotrexate 12g/m2 (10 cycles) Cisplatinum 120mg/m2; Doxorubicin 90mg/m2 Total length 34 weeks All the product are used as commercial formulation Other Names: methotrexate cisplatin doxorubicine
