简要总结
The purpose of this research study is to determine if the combination of chemotherapy and hormone therapy is safe and helpful for patients who plan to have their high-risk prostate cancer surgically removed. Some physicians believe that patients with high risk cancer that is located in one area, may have an early but small spread of the cancer outside of the prostate, and perhaps even to distant organs. Therefore, better treatments for the entire body are needed to improve the ability of surgery or other local therapies to cure prostate cancer. Since chemotherapy is beginning to demonstrate increasing activity in advanced prostate cancer patients, it is possible that using chemotherapy combined with hormonal therapy earlier in the course of localized but high risk patients might improve the outcomes for these patients.
详细描述
- Participants will receive treatment in the outpatient clinic, where the docetaxel chemotherapy will be placed in a bag of fluid and will be given by vein every three weeks. Participants will take Decadron (dexamethasone) by mouth 12 hours and 1 hour before docetaxel and again 12 hours after docetaxel. They will also take estramustine and casodex by mouth at home. Zoladex (or lupron) will be given subcutaneously (under the skin) 4 times every three months. They will also be started on coumadin beginning at the time of the first docetaxel infusion and continuing until 3 weeks after the 4th cycle of chemotherapy.
- After 2 months (or cycles) of therapy, participants will be evaluated in order to assess the response and toxicity of treatment, including a review of medical history, physical examination, blood tests, including PSA. If there is no evidence of progression or excessive toxicity, treatment will continue for 2 more months in the same manner.
- At the end of 4 months of chemotherapy, participants will be reassessed by the medical oncologist and urologist regarding surgery to remove the prostate.

结局指标
主要结局
Pathologic Complete Response Was Assessed by Rigorous Pathological Examination by One of Two Pathologists
时间窗: status post prostectomy
One of two pathologists (SR, EG), assigned the Gleason scores for each patient from pre-treatment prostate biopsies and assessed pathological staging on post- prostatectomy specimens. Staging including a description of all tumor foci within the gland, presence or absence of perineural invasion and/or lymphovascular invasion, presence of extraprostatic extension of tumor (including seminal vesicle invasion), and margin status. The pathologists reviewed the presence or absence of cancer in each prostate gland removed on the study patients. RECIST has to my knowledge not been used for pathological examination in neoadjuvant studies. 0 out of 28 participants acheived complete response. RECIST is not appropriate as cancer within the gland at the time of treatment is not measurable by RECIST. The primary outcome is a pathological complete response.
