Measure
Chemohormonal and Definitive Therapy After Prostatectomy
(1st) Systemic chemo-hormonal therapy with up to 6-months (\~24 weeks) of adjuvant androgen deprivation (Leuprolide Acetate) and up to 6 cycles of chemotherapy (Docetaxel), (2nd) definitive local tumor control with adjuvant radiation therapy, and (3rd) consolidative stereotactic radiation to oligometastatic lesions. The men will receive a total of 2 years of androgen deprivation. Androgen blockade (Bicalutamide) will be the same throughout the course of treatment. Leuprolide Acetate: 22.5mg by intramuscular (IM) injection every 3 months Docetaxel: 75 mg/m2 IV will be given on day 1 every 3 weeks, up to 6 cycles. Dose may decreased in the following intervals: 65 mg/M2, 55 mg/M2, 35 mg/M2. Bicalutamide: bicalutamide (Casodex) 50mg by mouth daily Radiation: Radiation will be delivered in 1 to 5 fractions, and the dose and fractionation schedule will depend on the size and location of the lesion and the surrounding normal tissue constraints in accordance with AAPM Task Group 101 recommendations. Typical doses include 16 - 24 Gy in 1 fraction, 48 - 50 Gy in 4 fractions, and 50 - 60 Gy in 5 fractions. Abiraterone Acetate: Abiraterone acetate 1000 mg / day may be given at the investigator's discretion.

SECONDARY outcome

Timeframe: 3 years

Population: Assessed all patients, from time of enrollment until study exit/3 years from enrollment.

To assess the safety of multimodality therapy in men presenting with newly diagnosed oligometastatic prostate cancer after prostatectomy. Toxicities related to neoadjuvant therapy, radiation therapy, or stereotactic body radiation therapy (SBRT) will be assessed using CTCAE version 4 criteria. Surgical toxicities will be assessed using the Clavien-Dindo Classification
