Active clinical trials for "Prostatic Neoplasms"

Rationale: This prospective study investigates the outcomes of daily online stereotactic MR-guided adaptive radiation therapy (SMART) in patients with localized prostate cancer (cT1c-T3bN0M0). Visualization of the prostate, rectum and bladder prior to and during radiation delivery can be used to deliver "gated" treatment (beam-on only when the prostate is in the predetermined position) using small uncertainty margins. The novel MRIdian treatment delivery system (ViewRay, USA), which will be used for this study, allows for the immediate generation of an optimal radiotherapy plan based on the current anatomy of the prostate and surrounding normal organs prior to each fraction. These major advances will (i.e. dosimetrically) allow for an optimisation of normal tissue radiation doses, which should theoretically decrease toxicity to surrounding organs such as the rectum or bladder. Another advantage of this approach is that online MR-based prostate imaging does not rely on implanted gold markers, avoiding an invasive procedure to insert such markers. If proven feasible, this approach could set a new standard of care for patients with localized prostate cancer. The main goal of this phase II study of SMART for prostate cancer is to evaluate the early and early-delayed toxicity, i.e. within the first year after treatment. An established 5-fraction hypofractionated radiation scheme will be used in this trial. Main outcome parameters will include gastro-intestinal, genitourinary and sexual symptoms, which will be monitored at fixed time points using CTCAE criteria. In addition, patient-reported outcomes will be evaluated using EORTC-QOL questionnaires. Objective: To investigate the early and early-delayed toxicity profile of SMART in patients with localized prostate cancer. Study design:phase II observational study Study population: 100 consecutive patients with localized prostate cancer (cT1c-T3bN0M0). Study intervention: Study patients will be treated with an online MR-guided hypofractionated course of radiotherapy in 5 fractions of 7.25 Gy per fraction delivered on the prostate with a simultaneous integrated sparing of the urethra with a dose of 32.5 Gy in 5 fractions Main study parameters: Early and early-delayed toxicity (CTCAE v. 4.0); (IPSS) and Qol C30 PR25. Secondary endpoint will be the offline evaluation of the dosimetric benefit of SMART by comparing cumulative doses to organs at risk.

To evaluate the negative predictive value of mpMRI in the detection of prostate cancer using cystoprostatectomy specimen as the reference

The Be-RALP database is Belgian prospective multicenter database governed by the Belgian cancer registry. This database investigates the status after robot assisted laparoscopic prostatectomy (RALP) in prostate cancer patients. It was established by a collaboration between the Belgian association of Urology (BAU), the National Institute for Health and Disability Insurance (NIHDI) and the Belgian cancer registry. Between 2009 and 2016, 9235 patients were included in this patient registry. The studied outcomes covered quality of life measures as well as variables covering urinary and erectile function.

This prospective study of comparing between Transrectal and transperineal prostate MRI targeted biopsy to provide evidence for clinicians to select the appropriate biopsy approach under different conditions.

The aim of this non interventional study is to describe the proportion of Belgian mCRPC patients which were treated with 1 to 4 and 5 to 6 Radium-223 injections and the patient characteristics which are potentially associated with this proportion.

The purpose of this study is to collect additional safety data until apalutamide is commercially available for participants with non-metastatic castrate-resistant prostate cancer (NM-CRPC).

The aim of the study was to evaluate the prevalence, the prognostic and predictive value of gene alterations in unselected patients with prostate cancer. Patients with histologically confirmed prostate cancer, treated at Hellenic Cooperative Oncology Group (HeCOG)-affiliated departments, were included. The presence of gene alterations was assessed using the ForeSENTIA® Prostate panel developed by NIPD Genetic.

Patients with advanced prostate cancer are often treated with the chemotherapy drug docetaxel. The manufacturers of this drug suggest using the same dose of drug per m² body surface area for all patients. However we know that individuals end up with more or less of the drug circulating in their blood even after they have been given the same dose. A software program (a "Dosing Tool") has been developed to provide information to doctors on how docetaxel will affect individual patients. The program may help doctors to make informed decisions about exactly how much drug to give to different people. The purpose of the PARTNER study is to gather information from blood tests on patients being treated with docetaxel to help in the further development of the Dosing Tool. Some of these blood tests would have been taken anyway as part of patients' routine treatment. Others are extra for this study. Apart from the additional blood tests, everyone who enters the study is treated just as they would normally be if they were not taking part in the study.

Single-center evaluation of all patients treated for primary localized prostate cancer with focal HIFU from November 2009 to December 2016. To evaluate midterm oncological outcomes of focal HIFU therapy in low an intermediate risk prostate cancer.

Patients with primary low and intermediate risk prostate cancer (PCa) for whom radical prostatectomy are indicated, will be invited to participate to the present study. The aim of this study is to investigate the clinical value of 68Ga-GRP positron emission tomography / computed tomography (PET/CT) compared to 68Ga-PSMA PET/CT in patients with low and intermediate risk PCa.
