signpost iconHigher radiation dose reduces recurrence of local prostate cancer

Bottom Line:

After nearly nine years of follow-up, men with early-stage prostate cancer who received higher doses of radiation were less likely than men who received the conventional dose to have rising levels of prostate-specific antigen (PSA)"”a phenomenon referred to as "biochemical recurrence" that may predict actual recurrence 15 years or more in the future.

Publication details:

This is a news item reporting the findings of a phase III trial that men with early-stage prostate cancer who receive higher doses of radiation were half as likely to see their cancer return in five years as men who received the conventional dose.
