Stereotactic Body Radiotherapy for Stage I-III Prostate Cancer

July 11, 2019 updated by: Swedish Medical Center

Function-Preserving Stereotactic Body Radiotherapy for Clinical State I-III Prostate Cancer

The purpose of this study is to find out the effects (good and bad) of highly focused radiation on you and your prostate cancer. The purpose of this evaluation is to see if this treatment causes fewer side effects that other standard treatment approaches, and to evaluate the effect of this treatment on your prostate tumor and your quality of life over time.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: CyberKnife Stereotactic Radiosurgery
This treatment concentrates large doses of radiation onto the tumor so that injury from radiation to the nearby normal tissue will be minimal. CyberKnife Stereotactic Radiosurgery is not investigational and is considered standard of care.
Radiation: CyberKnife Stereotactic Radiosurgery
Five treatments given over about one week.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Quality of life outcomes (low- and intermediate-risk prostate cancer groups)
Time Frame: 8 years
In the low- and intermediate-risk prostate cancer groups, to determine whether study treatment improves patient-reported quality of life outcomes compared to the approach used in a previous multi-center cyberknife stereotactic radiosurgery trial.
8 years
Rates of acute and late grade 3-5 gastrointestinal and genitourinary toxicities (high-risk group)
Time Frame: 8 years
In the high-risk group, to estimate rates of acute and late grade 3-5 gastrointestinal and genitourinary toxicities following cyberknife stereotactic radiosurgery.
8 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Rates of toxicities related to treatment
Time Frame: 5 years
After five years following cyberknife stereotactic radiosurgery, estimate rates of toxicities related to treatment.
5 years
Disease free survival
Time Frame: 5 years
Measure disease free survival after five years following cyberknife stereotactic radiosurgery.
5 years
Overall survival
Time Frame: 5 years
Measure overall survival after five years following cyberknife stereotactic radiosurgery.
5 years

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Quality of life
Time Frame: 5 years

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
