Brief Summary
This is a single-arm prospective non-randomized, non-blinded trial to assess the safety of neoadjuvant stereotactic body radiation therapy (SBRT) before surgery in high risk prostate cancer patients. Radiation therapy will be delivered over 5 treatment sessions for approximately 1.5 weeks total.

Outcome Measures
Primary Outcomes (1)
Maximum Tolerated Dose (MTD) of Neoadjuvant SBRT
The MTD is defined as the SBRT dose that with radical prostatectomy induces dose-limiting toxicity in 28% of subjects or less.
6-week post-prostatectomy
Secondary Outcomes (6)
Incidence of Urinary Incontinence
up to one year post treatment
Incidence of Urinary Stricture
up to one year post treatment
Incidence of Urinary Bother
up to one year post treatment
Rectal Toxicity
up to one year post treatment
Number of Patients with Positive Surgical Margins
4-10 weeks post radiation therapy
- +1 more secondary outcomes
Study Arms (1)
SBRT
EXPERIMENTALStereotactic Body Radiation Therapy (SBRT) will be delivered over 5 treatment sessions for approximately 1.5 weeks total.
Interventions
Delivered over 5 treatment sessions for approximately 1.5 weeks total.
Open, laparoscopic, or robotic radical prostatectomy and pelvic lymph node dissection to remove the prostate, seminal vesicles, and pelvic lymph nodes.
Eligibility Criteria
You may qualify if:
- Subjects must have biopsy-confirmed adenocarcinoma of the prostate.
- Subjects must have a negative bone scan.
- Subjects must have one of the following risk factors:
- PSA ≥20 and/or
- Gleason score ≥8 and/or
- Clinical or radiographic stage ≥T3a per AJCC (American Joint Committee on Cancer) 7th Edition Staging Manual and/or
- Radiographic pelvic lymph node positive disease and/or
- At least two out of four of the following: PSA (Prostate Specific Antigen) 10-19.9, GS (Gleason Score) = 3+4, clinical stage = T2b/T2c, ≥50% positive biopsy cores.
- Subjects must freely sign informed consent to enroll in the study.
- Subjects must be medically fit to undergo surgery determined by the PI.
- Age ≥ 18
- KPS Karnofsky Performance Status (performance status is an attempt to quantify cancer patients' general well-being and activities of daily life, scores range from 0 to 100 where 100 represents perfect health and 0 represents death): ≥70.
- No prior invasive malignancy in the past 3-years, except non-melanomatous skin cancer unless disease free for a minimum of 2 years. Carcinoma in-situ of the bladder or head and neck region is permissible.
- Subjects must not have had prior pelvic radiation therapy,
- Subjects must not have had prior androgen deprivation therapy in the past 6 months.
You may not qualify if:
- Metastatic disease as demonstrated by bone scan, CT scan or MRI (Magnetic Resonance Imaging) of the pelvis, or chest x-ray.
- Declared high-risk for anesthesia by attending anesthesiologist, cardiologist, or other physician.
- History of prior pelvic radiation therapy.
- History of androgen deprivation therapy within the past 6 months.
