State-of-the-art radiotherapy in the management of clinically localized prostate carcinoma.
Four Phase III trials demonstrating higher prostate-specific antigen control rates in prostate cancer patients treated with higher doses of radiation have changed the standard of care. Emerging on-line technologies, improved imaging and computer algorithms, combined with an improved understanding of how best to apply them, have allowed radiation oncologists to move ever closer to the optimal application of curative radiation. This technology allows a higher dose to be delivered to tumor-bearing areas while minimizing the dose delivered to surrounding normal tissues. Real-time adaptive techniques have made each step more accurate, and commercialization has increasingly moved these advances further into the community setting. Phase III trials have also helped to define the role of hormonal therapy in combination with radiation and the benefits of prophylactic pelvic nodal radiotherapy in subsets of patients. We have also learnt how to optimize the use of prostate-specific antigen to better determine success and failure following radiotherapy.
