Radiotherapy effectively manages bone metastases, with single or multiple fractions showing comparable efficacy. This review evaluates pain relief, reduced medication needs, bone healing, and re-irradiation requirements for optimal treatment strategies.

Area of Science:

  • Oncology
  • Radiation Oncology
  • Palliative Care

Background:

  • Bone metastases are a common complication of cancer, significantly impacting patient quality of life.
  • Radiotherapy is a cornerstone treatment for painful bone metastases.
  • Current practice often involves single-fraction (6-10 Gy) or multifraction (e.g., 30 Gy in 10 fractions) regimens.

Purpose of the Study:

  • To review and evaluate the efficacy of different radiotherapy fractionation schemes for bone metastases.
  • To assess key outcomes including pain response, analgesic reduction, bone recalcification, and need for re-irradiation.
  • To consider prognostic factors influencing treatment outcomes.

Main Methods:

  • Systematic review of randomized trials comparing radiotherapy fractionation for bone metastases.

  • Evaluation of efficacy based on pain response (partial/complete), reduction in analgesic intake, bone recalcification, and re-irradiation rates.
  • Analysis of influencing factors: primary tumor site, metastatic burden, performance status, and prognosis.

    • Main Results:

    • Evidence suggests comparable efficacy between single and multifraction radiotherapy for pain relief and functional improvement.
    • Multifraction schedules may offer advantages in bone recalcification and potentially reduce the need for re-irradiation in select cases.
    • Patient-specific factors significantly influence treatment outcomes and the risk of side effects.

    Conclusions:

    • Both single and multifraction radiotherapy are effective for managing bone metastases.
    • The choice of fractionation scheme should be individualized based on patient prognosis, symptom burden, and treatment goals.
    • Further research is needed to optimize radiotherapy protocols and minimize long-term side effects.
