Plain English Summary
Background and study aims
Prostate cancer is a common cancer, where many patients have such a slowly growing tumor that it is uncertain if they need treatment. Other patients have very aggressive tumors, and in Sweden with 10000 newly diagnosed prostate cancer patients 2500 will die each year. No scientific studies had in 1986 shown that any of the treatment options for localized prostate cancer expectancy or radiotherapy or surgery was superior. Expectancy had been the treatment of choice in the beginnings of the 1980s. The aim of this study was to evaluate if radiotherapy could prolong progression free survival and reduce mortality in comparison to expectancy.
Who can participate?
Patients with prostate cancer under the age of 75
What does the study involve?
Participants are followed for the progression of their symptoms and are offered radiotherapy. The use of four-field EBRT, 64 Gy, 2.0 cm margin was increased during the beginning of 1980’s, further technical improvements such as CT-based conformal radiotherapy was developed by the beginning of the 1990ies, dose was increased to 70 Gy with margins around 1-1.5 cm.
