The optimal duration of hormonal therapy is yet to be determined in the treatment of locally advanced carcinoma of the prostate. The RTOG performed a trial of 4 months of neoadjuvant and concurrent hormones(consisting of Goserelin and Flutamide) compared to radiation alone, and found that there was an improvement in local control and progression-free survival, but no improvement in overall survival. The EORTC performed a similar trial, but used Goserelin alone for a period of 3 years. This trial showed an improvement in local control, disease-free survival, and in contrast to the RTOG trial, an improvement in overall survival. The rate of erectile dysfunction in men who receive a prolonged period of Gosereline (i.e. 2 yrs) is not known, but suspected according to expert opinion, to be significantly higher than a shorter course of hormonal ablation. Therefore the price of of a survival advantage in locally advanced prostate cancer maybe at a cost of increased rates of erectile dysfunction.
The purpose of this study is to determine the ability of functional MRI techniques to detect, measure and locate intra-prostatic cancer.
Hypoxia (low oxygen level) is know to be present in many tumors and may strongly influence the success of treatment and the progression of disease in prostate cancer. The method used to measure tumor oxygen levels in prostate cancer is to place a needle in the prostate itself through the rectum. Blood oxygen level dependent imaging (BOLD MRI) is a special MRI technique that allows indirect assessment of oxygen levels in blood. This technique is non-invasive, involving no needles. BOLD has not been applied in humans in prostate cancer. The purpose of this study is to develop a MRI-BOLD technique that allows us to non-invasively measure changes related to tumor hypoxia in prostate cancer. This technique may provide information that will be an independent predictor of patient survival, tumor recurrence and likelihood of treatment response in prostate cancer
Prostate specific antigen (PSA) and digital rectal exam (DRE) are used to screen for prostate cancer. Patients with abnormal DRE or elevated PSA undergo transrectal ultrasound guided biopsy (TRUS-Bx). There are some men who have a normal TRUS-Bx despite persistent elevated PSA and may harbor occult prostate cancer. The purpose of this study is to determine if MRI using an endorectal coil, and advanced MRI methods called H1 MR Spectroscopy (MRS) and Dynamic MR Perfusion Imaging (dMRI) can help identify and localize prostate cancer in these patients and direct repeat TRUS-Bx to the most suspicious location in the prostate gland. 100 men, currently under observation with elevated PSA but negative TRUS-Bx will be enrolled in the study.
To evaluate activity of gefitinib in subjects with relapsed prostate cancer by estimating PSA response rate at study closure
The primary purpose of this study is to evaluate two treatment regimens for prostate cancer, prostate implant with 20 Gy of external beam radiation therapy versus prostate implant with 0 Gy of external beam radiation therapy. Patients diagnosed with intermediate risk prostate cancer between the ages of 40 and 80 who have chosen brachytherapy with or without external beam radiation therapy as their intended treatment will be eligible and will be offered participation.
Study to determine effectiveness and safety of zoledronic acid and whether it has a pharmaco-economic impact in prostate cancer with bone metastasis.
To estimate the safety and tolerability of 250 mg ZD1839 given concurrently with 3D-CRT in patients with non-metastatic prostate cancer
It is the aim of this clinical study to evaluate the skeletal-related event rate and tolerability of zoledronic acid in patients with prostate cancer patients and bone metastases.
