    Summary

    Neoadjuvant chemotherapy in osteosarcoma showed a 53% disease-free survival rate in 19 patients. Further studies are needed to confirm the value of this treatment approach for non-metastatic osteosarcoma.

    Area of Science:

    • Oncology
    • Medical Research

    Background:

    • Osteosarcoma is a rare bone cancer primarily affecting children and young adults.
    • Effective treatment strategies for non-metastatic osteosarcoma are crucial for improving patient outcomes.

    Purpose of the Study:

    • To evaluate the efficacy of two different neoadjuvant chemotherapy regimens in patients with non-metastatic osteosarcoma.
    • To determine the disease-free survival rate following pre- and postoperative chemotherapy.

    Main Methods:

    • A total of 19 unselected patients with non-metastatic osteosarcoma received two different chemotherapy combinations.
    • Chemotherapy was administered both preoperatively and postoperatively.
    • The median follow-up duration after chemotherapy cessation was 26 months.

    Main Results:

    • Nine out of 19 patients experienced treatment failure, with all cases developing pulmonary metastases.
    • Six patients died despite receiving salvage chemotherapy regimens.
    • The overall disease-free survival rate was 53%.

    Conclusions:

    • Neoadjuvant chemotherapy demonstrated a 53% disease-free survival rate in this cohort of non-metastatic osteosarcoma patients.
    • Longer follow-up and larger studies, such as the European Osteosarcoma Intergroup Study, are necessary to definitively establish the role of neoadjuvant chemotherapy.
