Area of Science:

  • Oncology
  • Radiation Therapy
  • Health Economics

Background:

  • External beam radiotherapy is a primary curative treatment for localized prostate cancer, the most prevalent cancer in men.
  • Conventional radiotherapy courses are lengthy (8-9 weeks), posing significant burdens on patients and healthcare systems, particularly in low- and middle-income countries.
  • Limited healthcare resources and patient finances in these regions exacerbate the challenges associated with prolonged treatments.

Purpose of the Study:

  • To evaluate the clinical and economic advantages of hypofractionated radiotherapy schedules compared to conventional fractionation for localized prostate cancer.
  • To assess the feasibility and potential benefits of implementing hypofractionation in resource-constrained healthcare settings.

Main Methods:

  • Review of clinical trials comparing hypofractionated and conventionally fractionated radiotherapy for prostate cancer.
  • Analysis of economic evaluations assessing the cost-effectiveness of different fractionation schedules.
  • Consideration of practical implementation factors for hypofractionation in low- and middle-income countries.

Main Results:

  • Clinical trials demonstrate equipoise between hypofractionated and conventionally fractionated radiotherapy, with hypofractionation drastically reducing treatment duration.
  • Economic evaluations indicate improved cost-effectiveness for hypofractionated therapy.
  • Modern consensus guidelines support the clinical implementation of hypofractionated schedules.

Conclusions:

  • Hypofractionated radiotherapy offers a shorter, cost-effective treatment for localized prostate cancer, supported by clinical evidence and guidelines.
  • While demanding advanced infrastructure and training, hypofractionation presents substantial potential gains for patients, especially in low- and middle-income countries.
  • Careful consideration of practical implementation challenges is necessary to maximize the benefits of hypofractionation in diverse healthcare settings.
