    Summary

    Radiation-induced bone sarcoma is a rare complication, occurring in 0.035% of survivors. The study concludes that the risk is too low to contraindicate modern radiation therapy.

    Area of Science:

    • Oncology
    • Radiotherapy
    • Bone Sarcoma

    Background:

    • Irradiation-induced sarcoma of bone is a known but rare complication following radiation therapy.
    • Assessing the incidence and risk factors is crucial for optimizing cancer treatment protocols.

    Purpose of the Study:

    • To determine the incidence of radiation-induced bone sarcoma.
    • To evaluate the risk associated with different radiation doses.
    • To assess if this complication contraindicates modern radiotherapy.

    Main Methods:

    • Review of ten cases of bone sarcoma fulfilling Cahan's criteria over twenty years.
    • Inclusion of data from three additional large series from the literature.
    • Deduction of a dose-complication curve based on combined data.

    Main Results:

    • Ten cases of irradiation-induced bone sarcoma were identified.
    • The overall incidence was found to be 0.035% among five-year survivors of radiation therapy.
    • A dose-complication curve was established using pooled data.

    Conclusions:

    • The risk of radiation-induced bone sarcoma is very low within the dose ranges used in contemporary radiotherapy.
    • This low risk does not constitute a contraindication for employing radiation therapy in cancer treatment.
    • Modern radiation therapy practices can be safely utilized despite the potential for rare complications like bone sarcoma.
