Changing trends in national practice for external beam radiotherapy for clinically localized prostate cancer: 1999 Patterns of care survey for prostate cancer
The significantly increased use of ADT for high-risk patients and higher radiation doses, especially for intermediate- and high-risk patients, reflects the penetration and growing acceptance of clinical trial results that have demonstrated the efficacy of these treatment approaches. The relatively high proportion of favorable-risk patients treated with high radiation dose levels was greater than expected. A large increase in brachytherapy was observed compared with prior surveys. Most treated patients with high-risk disease did not undergo elective WPRT, which likely reflects the influences of prior trials, stage migration, and the commonly held belief that WPRT provides minimal benefit in the setting of higher radiation doses.
