What was measured

Evaluation of delivering SBRT to the prostate using non-uniform dosing. The investigators will evaluate the potential for added grade 3 rectal toxicity with the use of a simultaneous integrated boost (SIB - Arm A). Acute toxicities were defined as occurring on-treatment or within 6 weeks.

Groups in this outcome

Grade 2 Toxicities: Arm A

Incidence of moderate GU toxicities on-treatment or within 6 weeks.

Grade 2 Toxicities: Arm B

Incidence of moderate GU toxicities on-treatment or within 6 weeks.

Grade 3 Toxicities: Arm A

Incidence of severe GU toxicities on-treatment or within 6 weeks.

Grade 3 Toxicities: Arm B

Incidence of severe GU toxicities on-treatment or within 6 weeks.
