    Summary

    The Japanese Registry of Bone Tumors tracked over 27,000 bone tumors. Adjuvant multidrug chemotherapy for osteosarcoma showed a nearly 70% five-year survival rate, while malignant fibrous histiocytoma had a 50.3% rate.

    Area of Science:

    • Oncology
    • Orthopedic Surgery
    • Cancer Research

    Background:

    • The Japanese Registry of Bone Tumors collected data on 27,665 bone tumors between 1964 and 1980.
    • Bone tumors represent a significant challenge in orthopedic oncology.

    Purpose of the Study:

    • To analyze treatment outcomes and survival rates for bone tumors in Japan.
    • To evaluate the efficacy of adjuvant multidrug chemotherapy for osteosarcoma.
    • To assess the prognosis of malignant fibrous histiocytoma.

    Main Methods:

    • Data compilation from the Japanese Registry of Bone Tumors (1964-1980).
    • Retrospective analysis of treatment and survival data for osteosarcoma patients receiving adjuvant multidrug chemotherapy.
    • Investigation of treatment and prognosis for 82 patients with malignant fibrous histiocytoma.

    Main Results:

    • The five-year cumulative survival rate for osteosarcoma treated with adjuvant multidrug chemotherapy was approximately 70%.
    • The five-year cumulative survival rate for malignant fibrous histiocytoma was 50.3%.

    Conclusions:

    • Adjuvant multidrug chemotherapy demonstrates considerable efficacy in improving osteosarcoma survival rates.
    • Malignant fibrous histiocytoma presents a poorer prognosis compared to osteosarcoma in this cohort.
    • Long-term data from national registries are crucial for understanding bone tumor treatment outcomes.
