September 2, 2020 updated by: Jaymeson Stroud, MD, Mercy Research

Phase IV Trial Evaluating the Use of Stereotactic Body Radiotherapy for the Treatment of Prostate Cancer

This study will evaluate the local control rate as well as acute and late toxicity rates of stereotactic body radiotherapy (SBRT) for the treatment of organ confined prostate cancer.

Detailed Description

This is a single site, non-randomized, prospective, phase IV trial of patients with organ-confined prostate cancer. Data collected will include patient demographics, pathology data, tumor stage, SBRT dose fractionation scheme, dose received by adjacent critical normal tissues,tumor recurrence data, and acute and late toxicities. Follow up data will be collected during the patient's standard office visits. The anticipated duration of this study is 5 years.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
OTHER: Stereotactic Body Radiotherapy
Patients will receive 30 - 40 Gy in 4 - 5 fractions. For high risk patients who also receive external beam radiotherapy, the SBRT will be given as 19 - 21 Gy in 2 - 3 fractions.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Biochemical Control Rate
Time Frame: one year
Serial blood tests for prostate specific antigen (PSA) levels will be obtained at regular intervals (every 3 months).The "Phoenix definition" for biochemical recurrence (nadir + 2 ng/ml) will be used. Biochemical control rate will be expressed based on subjects experiencing tumor control (complete, partial, or stable) vs. subjects experiencing disease progression.
one year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Late Toxicity Rate
Time Frame: one year
Toxicity will be recorded as a measure of patients who experienced adverse events within 1 year of study treatment.
