Filter by:This purpose of this study is designed to compare two types of images; magnetic resonance imaging (MRI) and Trans-Rectal Ultrasound (TRUS) to see which one performs more accurately for the image-guided insertion of Fiducial Markers(FMs) within the tumour. Though effective for guiding FM placement at the poles of the prostate gland due to excellent visualization of the prostatic boundaries, TRUS may not be ideally suited for marking the GTV. Conventional TRUS is neither sufficiently sensitive nor specific for accurate visualization of intra-prostatic tumor. A new interventional MRI technique enables needle guidance to the gross tumour Volume (GTV) for FM placement. It is of particular importance that both techniques be evaluated to enable which one is more effective so that it can be implemented in the designs of future trials involving dose-escalation to prostate.
Patients with diagnosis of HPIN were enrolled. Patients were randomized into two groups: dutasteride treatment group and watchful waiting strategy group. According to the study protocol the subjects would undergo 10 core biopsies after 6, 12, 24, and 36 months after randomization. There are assessed the rate of prostate cancer at repeated transrectal ultrasound guided biopsies and the effect of 5 alfa reductase inhibitor (dutasteride) on prevention of prostate cancer development for patients with high grade intraepithelial neoplasia (HPIN).
The PROTECT-PROvenge Treatment and Early Cancer Treatment trial was a Phase III trial for patients with hormone sensitive prostate cancer. The study was conducted at over 15 participating centers throughout the US. The purpose of the study was to determine if sipuleucel-T was effective for treatment of early stage, non-metastatic prostate cancer. The study compared the active vaccine to control to determine whether the product delayed the time until cancer progression.
RATIONALE: White button mushroom extract may stop or delay the development of recurrent prostate cancer. PURPOSE: This phase I trial is studying the side effects and best dose of white button mushroom extract in treating patients with recurrent prostate cancer after local therapy.
This study will look to see if the combination of ridaforolimus and bicalutamide works better than placebo and bicalutamide in men with prostate cancer.
to prospectively assess the health-related quality of life (HRQOL) changes during the first year after different treatment modalities for localized prostate cancer.
In this study we will test a new procedure to guide needle biopsies into the prostate gland based on MRI. This study will be conducted in patients who may have recurrence of their cancer in the prostate gland after radiation therapy in order to map out the location of the recurrence. Using this technique, we will be able to measure the accuracy of MR images in identifying the site of tumour recurrence.
The purpose of this study is to find out if men, with low-risk prostate, can have the small amount of cancer within their prostate removed by freezing, called Focal Cryoablation or Cryotherapy.
This is a prospective, serum proteomics study of men who are to undergo prostate biopsy. The purpose is to determine if proteomic profiles can be used to distinguish between men with prostate cancer on biopsy from men with no cancer on biopsy.
Background: Between 2000 and 2006, 433 patients were overexposed (8% to 10%) during a course of conformal radiotherapy for a prostate adenocarcinoma in Jean MONNET hospital, Epinal, France. Among them, twenty four patients received an additional mean dose about 20%, due to an inappropriate use of the treatment planning system. Severe adverse events (proctitis, cystitis, and tissue necrosis) have occurred among most of these overexposed patients. We propose to develop several research programs in order to increase the scientific knowledge on iatrogenic effects related to overexposure of ionizing radiation, by studying their relationship with dosimetric, clinical, biologic and genetic characteristics. Aim of the study: To correlate the received doses, the volume of irradiated normal tissues, the events, with biologic, phenotypic and genetic data. Primary study endpoint: Incidence and severity of adverse events related to radiotherapy (according to SOMA - LENT and CTCAE scales).
