Tidsramme |
|---|---|---|
|
To estimate the rate of chronic grade 3 - 5 genitourinary (GU) and gastrointestinal (GI) toxicity of SBRT either as a boost following conventionally fractionated IMRT or as a monoradiotherapy
Tidsramme: Periodical (baseline, during treatment, and at 1 month, 3 months, 6 months, 9 months, and 12 months post treatment. For the second and third years after therapy completion, follow-up visits will be every 6 months. Then annually for ____ years.
