The main purpose of this study is to find out whether adding radiation therapy to the standard treatment of chemotherapy for prostate cancer is tolerated well and is more effective than the standard treatment of chemotherapy alone
Most physicians would consider chemotherapy to be the standard for prostate cancer. In this study all participants will receive the standard chemotherapy. In addition, half the participants will also receive radiation therapy. It is hoped that the radiation therapy will provide additional benefit. The use of radiation therapy and chemotherapy for patients with this kind of cancer is not considered standard treatment at the present time.
Participants will be randomized into groups (or Arms) by a computer program. Participants randomized to Arm 1 will receive chemotherapy alone. Participants in Arm 2 will receive chemotherapy and radiation therapy. Participants in both groups (Arm 1 and Arm 2) will receive standard chemotherapy with docetaxel and prednisone. Docetaxel is given through a needle in a vein in the arm every 3 weeks or 21 days. Participants will take a prednisone tablet once per day until 21 days after the last dose of docetaxel. In addition, all participants will be given a drug called dexamethasone twice daily for 6 doses to help with the side effects of docetaxel. Participants in Arm 2 will first receive radiation therapy to the pelvis and prostate gland. Radiation therapy will be delivered once a day, five days a week for a total of 8-9 weeks. Then beginning 4-6 weeks after the end of radiation therapy, chemotherapy will be given, as described above. In both Arms, the total number of cycles of docetaxel and prednisone will depend upon how the tumor responds to these drugs. All patients should receive a minimum of three cycles of chemotherapy.

| Estimation of progression free survival(PFS) and response rate | The primary objective is to estimate the progression free survival (PFS) and treatment response of patients with non-metastatic or oligometastatic CRPC in the two study arms of either chemotherapy alone (ARM 1) or a combination of RT and chemotherapy (ARM 2). | Day one of each treatment cycle. cycles are every 21 days and at the end of post-treatment |
| Measure | Description | Time Frame |

| Overall survival of patients | One secondary objective is to estimate the overall survival of patients with non-metastatic or oligometastatic castrate resistant prostate cancer in the two study arms of either chemotherapy alone (ARM 1) or a combination of RT and chemotherapy (ARM 2). | at study completion and during follow-up (At least every 3 months (12 weeks) until evidence of progression or relapse for a maximum of 2 years, subsequently every 4 months for 2 years, then every 6 months for 2 years from the time of registration) |

| Multiple gene profiles will be analyzed. | Gene profiles using microarray techniques will be compared in order to identify genes important in governing the response to chemotherapy and radiation therapy in non-metastatic or oligometastatic castrate resistant prostate cancer. The expression and mutation of p53 gene, expression of androgen receptor (AR), PSA and neuroendocrine differentiation in non-metastatic or oligometastatic CRPC using immunohistochemical analysis will also be studied. | At Study Completion |
| Measure of prostate antigen-specific immune response | This secondary objective will determine if treatment of patients with non-metastatic or oligometastatic castrate resistant prostate therapy with chemotherapy, with or without radiation therapy, elicits prostate antigen-specific immune responses. | Every 21 days during treatment.
