研究概览
简要总结
This study is being done to test the safety of a single high-dose of radiation therapy before radical prostatectomy (removal of the prostate). The investigators want to find out what effects, good and/or bad, the radiation will have on men undergoing prostatectomy. The investigators are especially interested in men who are at risk for having cancer cells that have spread outside the prostate.

入选标准
- •Biopsy-proven prostate cancer verified at MSKCC. The biopsy will include a minimum of 10 cores
- •Radical Prostatectomy (RP) chosen as the therapeutic method
- •The size of the prostate will be < 70 cc by transrectal ultrasound or endorectal MRI imaging
- •No radiographic evidence of lymph node metastases, bone metastases or soft tissue disease
- •Risk of extraprostatic cancer of > 40% based on the MSKCC surgical nomogram
- •Age > or = to 18 years
- •KPS > or = to 80
- •Able to tolerate immobilization cradle positioning
排除标准
- •Allergic reaction to intravenous CT contrast (if premedicated, pt will not be excluded)
- •Prior radiation to the planned target region
- •Patients receiving concurrent chemotherapy
- •Neoadjuvant hormonal therapy Luteinizing-hormone-releasing hormone(LHRH)agonist and/or antiandrogen)
- •Prior transurethral resection of the prostate
- •Normal tissue directly overlying target precluding ability to limit the bowel, bladder, rectum or other tissue to less than or equal to 15-16 Gy dose constraints
- •Dominant prostatic lesion within 3 mm from the anterior rectal wall by imaging studies
- •Creatinine clearance <60 ml/min/1.73m2
结局指标
主要结局
To assess the feasibility and safety of single-fraction image-guided intensity modulated radiotherapy (IG-IMRT).
时间窗: 1 year
Given prior to radical prostatectomy (RP) in men at high risk for extraprostatic cancer.
次要结局
- To assess the effect of IG-IMRT on the anticipated positive margin rate at the time of RP.(1 year)
- To assess the long-term toxicity of intensity modulated radiotherapy (IG-IMRT)(weeks 3, 6, 9, 12, 18, 24, 30, and 36 months after RP)
- To analyze the changes in prostate perfusion induced by single-fraction IG-IMRT.(1 before radiation simulation, 1 after radiation treatment)
