Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
I. To compare the difference in the biochemical progression-free survival rate (bPFS) at 2-years between immediate androgen deprivation therapy (ADT) for nine months in high risk prostate cancer patients following radical prostatectomy and a similar high risk patient population followed without initiation of immediate ADT treatment.
SECONDARY OBJECTIVES:
I. To determine the difference in bPFS, prostate cancer specific survival, and overall survival between immediate ADT for nine months and observation for high risk prostate cancer patients following radical prostatectomy.
II. To evaluate the toxicity profile and quality of life (QOL) measured by Functional Assessment of Cancer Therapy-Prostate (FACT-P) and linear analogue self assessment (LASA) between two treatment arms.
TERTIARY OBJECTIVES:
I. To explore if serum and urine biomarker(s) levels at study entry, 9 months, or 24 months in the two treatment arms are correlated with biochemical progression-free survival rate.
II. To explore if \> 5 circulating tumor cells (CTCs) or circulating endothelial cells (CECs) following study treatments are associated with biochemical progression-free survival rate.
III. To explore the prognostic and predictive value of tissue based biomarkers in high risk prostate cancer patients.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM A: Patients receive leuprolide acetate intramuscularly (IM) on day 1 OR goserelin acetate subcutaneously (SC) on day 1. Courses repeat every 3 months for 9 months in the absence of disease progression or unacceptable toxicity.
ARM B: Patients undergo observation every 3 months for 9 months.
After completion of study treatment, patients are followed up every three months for 2 years.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Informed consent explained and signed prior to any study related procedures
* Patients with any one of the following "high risk" criteria:
* Clinical or pathological Gleason score 8-10
* Prostate-specific antigen (PSA) \> 20 ng/ml at initial presentation prior to radical prostatectomy
* Willingness to provide mandatory tissue for research purposes
* Willingness to provide mandatory blood for research purposes
* Has no history of androgen deprivation therapy within the past 6 months or has been treated neoadjuvantly up to 6 months prior to radical prostatectomy with the following agents; luteinizing hormone-releasing hormone (LHRH) agonists, anti-androgens, 5 alpha-reductase inhibitors, and peripheral anti-androgens
* REGISTRATION:
* Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2; or Karnofsky performance of \> 60%
* Patients with any one of the following "high risk" criteria:
* Gleason, prostate specific antigen, seminal vesicle and margin status (GPSM) score \>= 10 \[GS + 1\*(PSA 4-10)+2\*(PSA 10.1-20)+3\*(PSA \> 20)+2\*(seminal vesicular or nodal involvement) +2\*(margin)\](determined post radical prostatectomy)
* Post prostatectomy seminal vesicle invasion (pT3b) or pT4
* Two or less microscopic lymph nodal metastasis determined at the time of prostatectomy OR
* Gleason 4+3 at the time of prostatectomy with margin positivity
* Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase (SGOT) =\< 2 x institutional upper limit of normal (ULN)
* Total bilirubin =\< 2 x institutional ULN
* For patients identified as high-risk on the basis of pathological criteria after undergoing radical prostatectomy: interval time for study enrollment after radical prostatectomy will be =\< 28 days of the prostatectomy
* For patients identified as high-risk prior to undergoing radical prostatectomy: patients presenting with a high Gleason score (8-10) and/or a PSA \> 20 ng/ml are deemed eligible for study participation and study registration as long as the eligibility criteria is reconfirmed post radical prostatectomy; these patient groups may choose to register prior to or after prostatectomy
* Study randomization must occur =\< 28 days of radical prostatectomy; all patients consented on the trial, whether consented in the pre-prostatectomy or post-prostatectomy period, will be randomized to study treatments =\< 28 days of prostatectomy
* Ability to complete questionnaire(s) by themselves or with assistance
Exclusion Criteria
* Transitional cell, small cell, or squamous cell carcinoma of the prostate; NOTE: patients consented for participation prior to prostatectomy, if detected to have above listed histo-pathologies after prostatectomy will be deemed ineligible and not proceed to study randomization
* History of primary prostate cancer treatment
* Evidence of clinical nodal disease (N1) or grossly evident metastasis at the time of enrollment
* History of bilateral orchiectomy; unilateral orchiectomy with normal range serum testosterone levels will be allowed for enrollment
* Evidence of metastasis on radiographic metastatic workup within a preceding period of 4 months from the time of study entry, including whole body radionuclide bone scan, computed tomography (CT) and/or magnetic resonance (MR) scan of the pelvis and abdomen; otherwise will perform at the time of the baseline tests and result must be normal to continue on study; results of ProstaScint or other radionuclide scans, excluding radionuclide bone scans, will NOT be used to establish metastatic disease if all other studies are negative
* Receiving other experimental drugs =\< 4 weeks prior to consenting
* Uncontrolled infection
* History of other cancer, excluding squamous cell and basal cell skin cancers, within the preceding 2 years
* Documented history of human immunodeficiency virus (HIV) positivity or other acquired immunodeficiency disorder, congenital immunodeficiency disorder, or history of organ transplantation
* Unable to follow up every three months for the first year to Mayo Clinic, Rochester for receiving LHRH analogues or study monitoring
* REGISTRATION:
* Uncontrolled infection
* Unable to follow up every three months for the first year to Mayo Clinic, Rochester for receiving LHRH analogues or study monitoring
