Detailed Description
Prostate cancer remains the most commonly diagnosed, solid organ tumor and the second most common cause of cancer death in U.S. men. Technological advances have enabled new treatment options, such as stereotactic body radiation therapy (SBRT) and partial gland ablation (PGA). Although heavily marketed as more convenient with fewer side effects, there is an absence of high-level, comparative effective research (CER) to discern relative outcomes to traditional therapies such as active surveillance (AS), radical prostatectomy (RP) and intensity modulated radiation therapy (IMRT).
Investigators hypothesize that PGA will be associated with less reduction of urinary and sexual function compared to before treatment than both RP and IMRT. SBRT is hypothesized to be associated with less reduction of urinary and sexual function before treatment compared to RP and IMRT. SBRT is hypothesized to be associated with less reduction in bowel function compared to IMRT. PGA hypothesized to be associated with better overall quality of life at 12 months compared to AS. Investigators hypothesize PGA and SBRT will be associated with fewer adverse events compared to RP and IMRT.
The investigators will conduct a pragmatic, population-based cohort study of men with newly diagnosed low and intermediate risk prostate cancer in Southern California (SCa) and New York State (NYS) Surveillance Epidemiology and End Results (SEER) regions to bridge the evidence gap concerning adverse events and patient reported outcomes. This study will inform multiple stakeholders, who contributed to the study design. Stakeholders include prostate cancer survivors, payers, medical device manufacturers, professional organizations, community and academic prostate cancer experts and the Food and Drug Administration (FDA).

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Active Surveillance (AS)
Doctor will monitor the patient without directly treating the cancer.
|
Validated questionnaires administered at baseline, 8 months following treatment, and 12 months following treatment.
|
Stereotactic Body Radiation Therapy (SBRT)
Radiation treatment of prostate cancer requiring less than 2 weeks of treatment.
|
Validated questionnaires administered at baseline, 8 months following treatment, and 12 months following treatment.
|
Intensity-Modulated Radiation Therapy (IMRT)
Radiation treatment of prostate cancer requiring more than 2 weeks of treatment.
|
Validated questionnaires administered at baseline, 8 months following treatment, and 12 months following treatment.
|
Partial Gland Ablation (PGA)
Prostate cancer treatment that involves only treating part of the prostate that has cancer.
Examples include, but are not limited to, high intensity focused ultrasound (HIFU) and cryotherapy.
|
Validated questionnaires administered at baseline, 8 months following treatment, and 12 months following treatment.
|
Radical Prostatectomy (RP)
Prostate surgery that removes the whole prostate.

Time Frame |
---|---|---|
Assessment of Adverse Events following Treatment by Common Terminology Criteria for Adverse Events (CTCAE) v5.0
Time Frame: 8 months
|
All adverse events will be graded according to the Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Grade refers to the severity of the adverse event. The CTCAE displays Grades 1 through 5 with unique clinical descriptions of severity for each adverse event based on the general guideline: Grade 1 - Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 - Moderate; minimal, local or noninvasive intervention indicated; limiting age appropriate instrumental activities of daily living. Grade 3 - Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care activities of daily living. Grade 4 - Life-threatening consequences; urgent intervention indicated. Grade 5 - Death related to adverse event. |

Change in Patient-Reported Urinary, Sexual, Bowel, and Hormonal Function as Measured on Expanded Prostate Cancer Index Composite (EPIC-26)
Time Frame: Baseline, 8 months, 12 months
|
The Expanded Prostate Cancer Index Composite (EPIC-26) is a 26-item questionnaire, dichotomized by severity, assessing four domains: urinary, sexual, bowel, and hormonal function.
Each domain is scored 0-100, with higher scores indicating greater dysfunction.

Time Frame: Baseline, 8 months, 12 months
|
The Male Sexual Health Questionnaire - Ejaculatory Function and Related Distress (MSHQ-EjD) is a 4-item questionnaire measuring severity of ejaculatory dysfunction.
Degrees of bother, ejaculatory force, ejaculatory volume, and frequency of ejaculation are measured on a scale of 0-5, with higher scores indicating greater dysfunction.
