Intraoperative radiation therapy (IORT) allows safe, high-dose irradiation for improved local tumor control in specific situations. Integrating IORT into multimodality treatments enhances outcomes for advanced cancers.

Area of Science:

  • Oncology
  • Radiation Oncology
  • Surgical Oncology

Background:

  • Modern intraoperative radiation therapy (IORT) originated from studies at the University of Kyoto.
  • Extensive research in Japan, Europe, and the US followed, establishing IORT's clinical potential.
  • Experience demonstrates the safety of delivering single high doses of irradiation during surgery.

Purpose of the Study:

  • To review the established role and future potential of intraoperative radiation therapy (IORT).
  • To highlight IORT's contribution to improved local control and survival rates in specific malignancies.

Main Methods:

  • Review of clinical investigations and treatment programs involving IORT.
  • Analysis of outcomes for patients with rectal carcinoma and retroperitoneal sarcoma treated with IORT.

Related Experiment Videos

  • Evaluation of IORT integration within multimodality treatment paradigms.

    • Main Results:

    • Single high doses of irradiation via IORT are safe in select clinical scenarios.
    • IORT, combined with surgery and external beam radiation, improves local control for rectal cancer and sarcomas.
    • Excellent local control and survival rates have been achieved in treated patient cohorts.

    Conclusions:

    • Intraoperative radiation therapy (IORT) is a valuable tool for improving local tumor control.
    • The future of IORT lies in its synergistic integration with chemotherapy, external beam radiation, and surgery.
    • Multimodality treatment programs incorporating IORT offer promising outcomes for locally advanced malignancies.
