Area of Science:

  • Oncology
  • Radiation Oncology
  • Medical Physics

Background:

  • Radiotherapy has significantly evolved, impacting oncological practice.
  • It contributes to increased organ-sparing treatments, improved local control, and enhanced survival rates.

Purpose of the Study:

  • To review major advancements in radiotherapy over recent years.
  • To highlight the impact of these changes on cancer treatment and patient outcomes.

Main Methods:

  • Review of recent developments in radiotherapy.
  • Discussion of innovations in radiobiology, fractionation schedules, and accelerator technology.
  • Examination of advancements in computerized treatment planning and quality control.

Main Results:

  • Approximately 50% of breast cancer patients now receive breast-conserving therapy.
  • Organ preservation strategies have advanced for head and neck, anus, bladder, and soft tissue sarcoma cancers.
  • New fractionation schedules (hyperfractionation, accelerated fractionation) optimize tumor dose and manage proliferation.
  • Three-dimensional conformal radiotherapy (3D-CRT) allows for precise dose escalation to tumors while sparing normal tissues.
  • Improved quality control and standardization enhance treatment delivery and results.

Conclusions:

  • Radiotherapy innovations have led to significant improvements in cancer treatment.
  • These advancements facilitate organ preservation, better local tumor control, and improved patient survival.
  • Continued progress in technology and standardization promises further enhancements in oncological care.
