Active clinical trials for "Prostatic Neoplasms"

The CamPROBE study investigates the rate of infective complications using the Cambridge Prostate Biopsy Device method of local anaesthetic transperineal prostate biopsies.

Prostate specific membrane antigen (PSMA) is a unique membrane bound glycoprotein, which is overexpressed on prostate cancer cells and is well-characterized as an imaging biomarker of prostate cancer. Studies have shown that PSMA PET/CT can detect prostate cancer lesions with excellent contrast and a high detection rate even when the level of prostate specific antigen is low. PSMA imaging is considered the gold standard in imaging of biochemical recurrence, with detection rate of recurrence in 79.5% of patients, in the largest series of 1007 patients. Despite these excellent results, there remains approximately 20% of patients in whom the site of biochemical recurrence cannot be identified and further research is needed into improving detection rates. Androgen deprivation therapy (ADT), represents the standard of care treatment for most men with a rising serum PSA and no evidence of disseminated disease on imaging modalities. There has been some preliminary data that imaging patients early after initiation of ADT therapy may increase detection rates of recurrence sites. The objective of this study is to evaluate if prostate cancer patients with biochemical recurrence and negative PSMA PET/CT can demonstrate in-vivo upregulation of PSMA receptors in an attempt to improve detection rates of recurrent prostate cancer. Patients who are started on ADT when clinically indicated, will have repeat PSMA PET/CT at 4 weeks following initiation of ADT therapy.

In this study, the investigators intend to validate 18F-DCFPyL test-retest reproducibility in metastatic lesions, in order to investigate whether it serves as a reliable response assessment tool, both to interpret existing studies and to design future longitudinal trials.

The investigators are imaging patients with prostate cancer using a new Positron Emission Tomography (PET) imaging agent (Ga-68-PSMA-11) in order to evaluate its ability to detect prostate cancer.

The aim of the present feasibility study of a new short palliative radiotherapy regime that apply to patients with metastatic hormone refractory prostate cancer (HRPC) presenting with a dominating debilitating symptom. Diffusion weighted magnetic resonance imaging (DWI) will apply to identify both the lesion and the most aggressive part of the lesion. The symptomatic lesions will be treated with a dose of 4 x 5 Gy, while for the most aggressive part of the lesion the dose will be escalated to 4 x 7 Gy using a simultaneous integrated boost (SIB) technique.

Men with localized prostate cancer are analyzed. Purpose: This randomized study compares outcomes between robotic-assisted radical prostatectomy and laparoscopic radical prostatectomy

Current research suggests that diets rich in multiple food types (such as broccoli, onions and garlic) are beneficial to our health and may reduce the risk of some cancers, including prostate cancer. The purpose of this study is to investigate the relationship between ingestion of the bioactive compounds from broccoli and garlic, and prostate metabolism.

Determine diagnostic accuracy of Axumin-PET positive bone lesion by confirmatory bone biopsy.

The purpose of this study is to assess the detection rate of local relapse after radical prostatectomy with either PSMA or 64Cu-PET/CTs and whether the delineation of relapsed lesions using both methods can facilitate/change the therapeutic strategy of the radiation oncologist

The overall goal is to provide an innovative approach to restage patients with biochemical recurrence of prostate cancer by using hybrid PET/MR with innovative radiotracers (68Ga-PSMA and 68Ga-RM2)
