Shorter, Intensive Radiation Can Be Recommended in Early Prostate Cancer

This study has implications for public policy,” said the study’s principal investigator, W. Robert Lee, M.D., a professor in the Department of Radiation Oncology at Duke. “Because the shorter regimen has advantages such as greater patient convenience and lower costs, it’s important to establishing whether we can cure as many patients with the shorter regimen. Our study provides that information for the first time.” Lee and colleagues, working as part of NRG Oncology, a non-profit cancer research organization, enrolled about 1,100 men whose prostate cancer was diagnosed early, before it had spread. Roughly half the patients were randomly assigned to receive the typical regimen of 41 treatments; the other half received the higher dose over just 28 treatments. At five years, disease-free survival was no different between the two groups, with 85.3 percent of men in the traditional group being cancer-free, compared to 86.3 percent of men in the shorter regimen group. Overall survival at five years was also no different, at 93.2 percent and 92.5 percent respectively. Mild gastrointestinal and genitourinary toxicity as reported by doctors was observed more frequently in patients getting the higher daily dose, shorter frequency radiation, but no differences were observed in more severe side effects, which were rare (less than 5 percent) with either regimen. The researchers also asked patients to describe their own experiences of side-effects, but these data have yet to be a...
