Filter by:This study will evaluate the local control rate as well as acute and late toxicity rates of stereotactic body radiotherapy (SBRT) for the treatment of organ confined prostate cancer.
The primary aim of study is to gain an initial assessment of safety and tolerability of AZD3514 in Japanese patients together with assessing Pharmacokinetics (PK) and gaining a preliminary assessment of anti-tumour action. In this study, AZD3514 will be administered to Japanese patients with metastatic castration resistant prostate cancer.
One of the biggest problems facing prostate cancer patients and their treating physicians is who needs to be treated and when. Common clinical and pathological parameters are useful (PSA, Gleason score, etc.) but do not clearly predict who will benefit from treatment and who will fail. Genetic markers for tumor aggressivity would be of greater value. The finding that the TMPRSS2-ERG gene fusion is associated with an increase risk of cancer progression is important. TMPRSS2 is controlled by androgen (testosterone) and ERG is part of a family of proteins which have a role in controlling cell growth, cell specialization and producing tumors. As a consequence of this gene fusion, production of the ERG protein increases in the presence of testosterone and could be key to the development of prostate cancer, resistance to treatment and poor outcome. The PTEN gene is known to have a role as a tumor suppressor. Its deletion is a contributing factor in the development of prostate cancers and poor outcome. The coexistence of the two markers could be associated with a higher risk of recurrence. To date there have been no studies regarding the presence of either of these two markers or their coexistence in high risk prostate cancer patients who, despite radiation therapy and androgen suppression, develop biochemical failure (their PSA levels rise once again). Patients participating in the PCS IV study (high risk prostate cancer treated with radiation therapy plus either 18 or 36 months of hormonal suppression) who have had biochemical failure or 3 years of follow-up post hormonal therapy will be approached. Tumor blocks from consenting patients will be collected and analyzed for the presence of the TMPRSS2-ERG gene fusion and the PTEN deletion at the Pathology Department of the Jewish General Hospital. Statistical analysis will be carried out to see whether either or both markers are present, whether they are associated with certain clinical and pathological high risk factors, and whether they can be used to predict which patients will fail treatment.
The investigators want to evaluate if preoperative MRI improves the surgical results, especially in respect to surgical margins. The impact on the surgical procedure will be evaluated. In addition the investigators will examine the accuracy of tumor detection, localization and staging.
Diagnostic delays in ambulatory care are often due to breakdowns of related care processes. Electronic systems can improve follow-up and reduce delays by detecting missed appointments or incomplete procedures so that patients are called back to conduct timely investigations when appropriate. To achieve high standards of patient safety in cancer diagnosis, the investigators not only need to use information technology appropriately but also improve the processes, policies, and procedures of monitoring, communication, and coordination of care. Given the importance of cancer-related diagnostic delays in ambulatory care, the investigators need effective methods to detect them, understand their causes, and intervene to reduce them. Manual techniques to detect these delays, such as spontaneous reporting and random chart reviews, have limited effectiveness. Our proposed study focuses on testing methods to proactively identify delays using certain "triggers" as they occur and intervene in a timely manner.
The purpose of this study is to determine if patients initiating androgen deprivation therapy (ADT) for prostate cancer can be transitioned from degarelix acetate to leuprolide acetate after an initial three-month period without a rise in serum testosterone. The investigators expect testosterone will quickly and reliably reach castrate levels after initiation of ADT and will remain castrate during the transition, and there will be no "testosterone surge" after leuprolide injection.
The purpose of this study is see if quality of life is improved in patients receiving oral hormone therapy compared to standard of care. The study will also compare survival rates between patients receiving oral hormone therapy and those receiving standard of care.
The investigators are trying to find new methods to treat prostate cancer. The approach the investigators are taking is to try to enhance patients' own immune response against the cancer. In this study the investigators will be testing the effectiveness of a vaccine that may be able to help the body fight prostate cancer.
A robotic brachytherapy device will be used to assist physicians in performing seed implantation to the prostate. EUCLIDIAN is the first robotic system designed to allow automatic placement of radioactive seeds by robot and thus reduce operator dependence. The clinical study is designed to evaluate the dosimetric quality, accuracy and patient self-reported quality of life scores after robotic brachytherapy.
Multicenter open label, uncontrolled study that enrolled men with metastatic castrate resistant prostate cancer previously treated with sipuleucel-T in the androgen dependent setting in the Dendreon P-11 study. The study was divided into Active and Long Term Follow-up (LTFU) Phases.
