Active clinical trials for "Prostatic Neoplasms"

This phase 2 waitlist-controlled, randomized trial is designed to compare the difference in proliferative index (Ki67) between carbohydrate restricted diet and usual care over a 6 month period in men with prostate cancer who have been placed on Active Surveillance. Eligible patients include men over 18 years old, BMI >25, with their most recently performed biopsy pathologically confirming prostate adenocarcinoma who have been placed on AS. Arms of the trial will be randomized 1:1 in a crossover approach, with Arm A receiving a carb restricted diet over 6 months then SOC and Arm B receiving the waitlist control arm (i.e. SOC then allowed to go on diet after 6 months). Ki67 will be performed on tissue from the most recent biopsy at the beginning of the study and again on tissue obtained in the 6 month SOC biopsy. Every patient will be on the study for 12 months, and the study will continue for approximately 3.5 years.

The Trans-Atlantic Prostate Group (TAPG) was established to examine the hypothesis that through a detailed retrospective analysis of outcome in a group of men with clinically localised prostate cancer at diagnosis, variables such as biological, pathological and clinical markers, could be identified that might accurately predict the prognosis of clinically localised prostate cancer.

This is an open-label, phase II trial in patients with PSA recurrence after prostatectomy. Patients entering the study will all receive initial 50 Gray (Gy) radiotherapy (25 x 2Gy) to the prostate bed and thereafter be classified as either responders or non-responders depending on PSA response at fifth week of radiotherapy. A 68-Ga- PSMA-PET is done before start of radiotherapy, and analyzed before fifth treatment week in order to identify cancer lesions in patients with poor PSA response. Patients with PSA response after 5 weeks of radiotherapy will not receive any subsequent therapy, whilst patients with poor PSA response may be in need for additional therapy such as radiotherapy to lymph node metastases and/or boost fractions to local recurrence. Patients with more than 3 lymph node metastases or distant metastases will not receive any more radiotherapy, but individualized systemic therapy will be started.

A randomized comparison clinical trial will be conducted in laparoscopic radical prostatectomy patients in the Weinberg PACU at the Johns Hopkins Hospital. 50 patients will be recruited and randomly assigned by a table of random numbers to either the music listening group (n=35) or the relaxation breathing group (n=35).

We aim to employ targeted DNA NGS to evaluate the prevalence of germline and somatic mutations in cancer predisposing genes, such as BRCA1 and BRCA2, and other HR and DDR genes, including also a few additional clinically relevant genes, in patients with metastatic, locally advanced or high-grade prostate cancer. In addition, we will investigate the prognostic role of these mutations as well as their association with various clinicopathological parameters. This will be the first study investigating the prevalence of germline and somatic pathogenic mutations in Greek patients with prostate cancer.

This study seeks to analyse MRI images and biological samples from 60 men diagnosed as having intermediate risk prostate cancer at baseline and one year afterwards to compare the molecular, genetic and transcriptomic differences between cancers that progress and cancers which do not.

This is an open label phase II, single-arm, biomarker multi-institutional pilot study. Men with progressive metastatic castration-resistant prostate cancer (mCRPC) who have been treated with androgen deprivation therapy (ADT) and at least one prior second generation AR-targeted therapy (either abiraterone or enzalutamide) will be enrolled in this study. All patients will receive treatment with testosterone cypionate 400 mg, intramuscular, every 28 days for a maximum of 3 cycles or limiting toxicity, if it occurs before the end of the scheduled therapy. After 3 cycles of BAT (12 weeks), patients may continue receiving this therapy off study at the discretion of the treating physician, if clinical/radiographic benefit. During the study period, patients will have plasma collected for cell-free tumor DNA analysis and CTC ARV7 status and also will perform 68Gallium-PSMA PET at baseline and then every 6 weeks.

ReIMAGINE Prostate Cancer Risk is a multi-centre, prospective, observational, longitudinal cohort study of men referred to secondary care with a suspicion of prostate cancer. The aim of the study is to develop a robust baseline risk stratification system for men at risk of prostate cancer. Men whose serum Prostate Specific Antigen (PSA) level is 20ng/ml or less, whose multi-parametric magnetic resonance imaging (mpMRI) scan has been scored as Prostate Imaging Reporting and Data System (PIRADS)/LIKERT score 3, 4 or 5, and who have been advised and accepted the need for a targeted and systematic prostate biopsy will be invited to take part in the study and be asked to donate blood, urine, imaging files and prostate biopsy for biomarker analysis.

The purpose of this study is to demonstrate the pharmacodynamic equivalence of triptorelin pamoate (Pamorelin® LA 11.25 mg), applied either IM or SC, in terms of the area under the curve [AUC1-85day] for serum testosterone in patients with advanced prostate cancer.

Standard treatment of locally-advanced prostate cancers consists in the association of radiotherapy of prostate and seminal vesicles (SV) and androgen deprivation (AD) for 3 years. This treatment is usually preceded by pelvic lymphadenectomy to assess the possible extension to lymph nodes of prostatic cancer and to avoid irradiating the pelvis in case of no lymph node involvement. However, radiotherapy leads usually to about 30% of grade ≥2 risk of bladder and/or rectal toxicity. This risk particularly depends on the radiation volume. In the aim of lowering the toxicity, the treatment in this study will associate: pelvic lymph node dissection and resection of seminal vesicles, allowing decreasing the radiation target volume to the prostate only (and not to irradiate the SV); a high-precision radiotherapy technique combining Intensity Modulated Radiation Therapy (IMRT) and Image-Guided Radiation Therapy (IGRT).
