Active clinical trials for "Prostatic Neoplasms"

The integration of magnetic resonance imaging (MRI) in the treatment planning process for prostate cancer will reduce uncertainties in delineation of the prostate gland, and will enable delineation of the urethra, penile bulb, and internal pudendal artery. The integration of daily cone-beam computed tomography (CBCT) will markedly reduce set-up uncertainties, thereby reducing the minimum planning target volume (PTV) margin. By combining MRI simulation and daily CBCT, and by adapting radiation delivery accordingly, the investigators will reduce dose delivered to the rectum, bladder, urethra, and erectile structures. In this study, the investigators seek to determine whether this dose reduction translates to improved patient outcomes. In a prospective, 2-stage design, up to 190 patients will be enrolled. In the first stage, advanced imaging will be integrated without altering dose planning techniques. Stage 2 will reduce dose delivered to normal tissues, and will collect toxicity outcome measures. This clinical trial will be conducted over 3 years.

This study examines information from patients with prostate cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). By collecting biological samples (like blood, urine, and tissue), and health information (such as treatment, diet, and quality of life) researchers hope to learn more about prostate cancer and ways to improve outcomes in the future.

Under the prostate cancer screening protocol of the project 'Prevention of Obesity-related Cancers', men with elevated PSA with higher prostate cancer risk (PSA 4-10 ng/mL with high Prostate Health Index (PHI) ≥35, or PSA>10 ng/mL) will be offered a prostate biopsy. In the current study, we would like to offer all screened men with elevated PSA in the range of 4-50 ng/mL a biparametric non-contrast MRI prostate (screening protocol) for any suspicious lesion in the prostate. If there is MRI lesion seen, additional targeted biopsies can be performed on top of the standard systematic prostate biopsies. It has been shown in a clinical Caucasian cohort that doing MRI-targeted biopsies resulted in improved detection of clinically significant prostate cancer compared with standard systematic biopsies. In this study investigators would like to investigate the benefits of adding MRI prostate and MRI-targeted biopsy in the diagnostic pathway for prostate cancer in a screened cohort of Chinese men at risk of prostate cancer.

PyL, also known as [18F]DCFPyL, is a second-generation fluorinated prostate-specific membrane antigen (PSMA) targeted PET imaging agent. In preliminary studies it demonstrates a higher detection of metastatic prostate lesions compared to standard imaging. Its ability to image metastatic prostate cancer sites was comparable to 68Ga-PSMA with high tumor-to-background ratios.Additionally, [18F] PyL demonstrated higher mean tumor-to-background ratios when using kidney, spleen, or parotid as reference organs. However, the role of [18F] PyL in tumor response to therapy has not been evaluated, specifically the potential to serve as a predictive biomarker of response. Given the high cost of current therapeutic agents in mCRPC, there is a need for an early response biomarker to stratify which patients will benefit from therapy and which will not. This will also allow for earlier change in management of patients who will not response to these therapies, potentially improving patient outcomes.

The goal of this observational study is to test whether the ExoDx Prostate test add value in biopsy decision making to patients with prostate cancer on an active surveillance regimen.

This study collects urine from male patients seen at the urology clinic to detect prostate cancer cells, shed in voided urine, using the optical imaging method developed in the laboratory, which targets certain biomarkers expressed on prostate cancer cells. The information learned from this study may allow researchers develop a simple diagnostic test for the management of those patients who have elevated prostate specific antigen (PSA) and are suspected to have prostate cancer. It may also help researchers understand the genetic risk factors associated with prostate cancer.

The purpose of this study is to compare two different techniques to perform the standard of care surgery to treat prostate cancer. This surgery is called robotic radical prostatectomy. There are two robotic surgical systems approved by the Food and Drug Administration (FDA) to perform this surgery. First system is called the Da Vinci ® Xi system. With this system, six small incisions are made during the surgery. Second system is called the Da Vinci ® SP system. With this system a single incision is made during the surgery. Same surgery is done with each surgical system. This study aims to understand whether a single incision surgery ends up with better recovery after surgery.

This prospective phase II study assesses the accuracy of second generation prostate specific membrane antigen (PSMA) positron emission tomography (PET; utilizing 18F-PSMA-1007)) and multiparametric magnetic resonance imaging (MRI) for locoregional staging of clinically significant prostate cancer in men undergoing radical prostatectomy and bilateral pelvic lymph node dissection. The design will be a multicenter validating-paired cohort study using radical prostatectomy and pelvic lymph node dissection as the gold standard comparator. Each patient will undergo both 18F-PSMA-1007 PET and 3T MRI allowing comparison of each imaging modality within each subject. Furthermore, PET and MRI will be compared to standard-of-care imaging techniques (CT abdomen/pelvis and 99mTc-MDP Bone scan).

Survival outcomes in metastatic prostate cancer in the population Brazilian - analysis of individual characteristics and modalities of treatment in different national health institutions

This study assesses the health literacy and understanding of radiation therapy information during consultation in patients with prostate or breast cancer undergoing definitive radiation therapy. Health literacy is defined as "the capacity to obtain, process, and understand health information and services to enable sound health decisions." Information gained from this study, may help researchers develop appropriate modalities to enhance comprehension of radiation therapy, and therefore allow for improved patient decision making with medical treatment.
