    Treating osteosarcoma during pregnancy requires prompt amputation or resection and adjuvant systemic chemotherapy. Early intervention with chemotherapy after delivery or termination can improve survival rates for pregnant patients with osteosarcoma.

    Area of Science:

    • Oncology
    • Obstetrics & Gynecology
    • Skeletal Oncology

    Background:

    • Osteosarcoma is a rare bone cancer. Pregnancy can complicate its diagnosis and treatment.
    • Limited data exists on managing osteosarcoma in pregnant patients.

    Observation:

    • Four pregnant women with osteosarcoma were treated.
    • Two patients received treatment before delivery, and two after.
    • All patients underwent amputation and received combination chemotherapy.

    Findings:

    • Two of the four patients survived.
    • One survivor was tumor-free, while the other had metastases.
    • Chemotherapy regimens included vincristine-cyclophosphamide or adriamycin-cyclophosphamide, followed by methotrexate with leucovorin rescue.

    Implications:

    • Adjuvant systemic chemotherapy is crucial for preventing metastases in pregnant osteosarcoma patients.
    • Treatment should involve amputation/resection and potentially early termination of pregnancy.
    • Multidisciplinary management is essential for optimizing outcomes in this challenging patient population.
