Filter by:The incidence of prostate cancer is rising however the number of deaths from prostate cancer is stable. Meaning the investigators are diagnosing many men with prostate cancer that will not impact on their life. The rise in incidence is mainly due to increased use of the blood test Prostate Specific Antigen (PSA), as a screening test. Currently men suspected of having prostate cancer, identified by a raised PSA undergo trans-rectal ultrasound guided prostate biopsy (TRUS biopsy). Many men have this test unnecessarily, only 1/3 being diagnosed with prostate cancer. TRUS biopsy is problematic as it is random and performed blind-the operator does not know where the cancer is. Thus many low-risk cancers that do not need treating are diagnosed and many high risk cancers are missed or incorrectly classified. So, men with a negative biopsy or those with low risk disease are usually advised to undergo another TRUS biopsy. An imaging test is needed that could help men and their doctors decide whether the biopsy is a true reflection of what is inside his prostate. The investigators will test the role of two imaging tests. The first, multi-parametric magnetic resonance imaging (mp-MRI) uses magnetic signals from the body to form images. The second, Prostate HistoScanning™ (PHS) uses sound-waves. The investigators will compare the results of these tests with a detailed biopsy map-transperineal template prostate mapping biopsy (which is currently the best way to find out what is in the prostate but requires multiple biopsies to be taken under general anaesthetic. Eligible men will have undergone one or more TRUS biopsies and who have been advised to have further tests on as part of standard of care. They will be recruited from UCLH referral letters and clinics. The investigators aim is to see if either of these tests can confidently rule out the presence of clinically important disease.
Hypofractionated regimen in high-risk prostate cancer will allow the investigators to deliver higher biological doses to targets in order to improve tumor control and with acceptable rectal toxicity compared to conventional fractionation.
The purpose of this study is to assess the androgen deprivation therapy when patients with castration-resistant prostate cancer are treated with docetaxel-based chemotherapy.
This trial is to determine if prostate target delineation obtained through an ultrasound based system is equivalent in accuracy to the MRI image fusion, and if alignment correction vectors obtained from ultrasound imaging are of equivalent accuracy to orthogonal X-ray imaging for daily prostate positioning.
This trial will evaluate whether the following aspect of surgical technique influence outcome: Lymph node dissection. In some patients, scans taken before surgery show that a lymph node has cancer. Surgeons make sure to remove those affect lymph nodes and all other lymph nodes in the area. However, it is not known whether removing lymph nodes helps prostate cancer patients whose scans do not show positive nodes. In this study, patients with clear scans will either receive a lymph node dissection or not."
This is an open-label randomized clinical study comparing primary prostate cryoablation alone (No-ADT group) with cryoablation plus short-term adjuvant androgen-deprivation therapy (Adj-ADT group) in the treatment of patients with high-risk localized prostate cancer.
This study will investigate health related quality of life factors in patients undergoing low dose rate prostate brachytherapy. Patients will be randomized to Iodine-125 Thinstrand (for use with 20 g needles) or Rapidstrand (for use with standard 18 g needles). Urinary, bowel, sexual function and bother will be measured by the EPIC questionnaire at various time intervals.
The pupose of this study is to assess the effectiveness of Samarium 153 administration, as determined by a 30% decline in the PSA within 12 weeks, as compared to baseline, in a population of men with high risk, clinically non-metastatic prostate cancer after a radical prostatectomy.
Given the activity of docetaxel in patients with progressive, metastatic castration-resistant prostate cancer, this study is being undertaken to evaluate the activity of tesetaxel, an orally bioavailable taxane, in chemotherapy-naive and chemotherapy-exposed patients.
To address pertinent questions regarding the utilization of stereotactic Body Radiotherapy (SBRT) to treat prostate cancer. The Florida Robotic Radiosurgery Association (FRRA) launched the first registry for prostate cancer patients treated with SBRT. The registry is designed to track surrogate treatment endpoints including prostate specific antigen (PSA), international prostate symptom score (IPSS),sexual health in men (SHIM), and visual analogue scale (VAS) scores, in addition to physical and survival data. Utilizing an independent vendor (Advertek, Inc.) experienced with the design and implementation of similar electronic registries, FRRA developed a data collection tool that staff members with a basic medical background can use to register and upload pertinent patient data, requiring no more than 20 to 30 minutes per patient. Participating patients will be monitored in follow-up for three years, with analysis and publication of the results semi-annually.
