Active clinical trials for "Prostatic Neoplasms"

Although the number of recommendations against systematic screening of prostate cancer, 70% of patients still request testing because they overestimate the benefits and are unaware of the limitations. The investigators aim is to assess the impact of a short printed decision aid presenting benefits and limits of screening, on patients' intent to undergo prostate cancer screening.

Toward personalised treatment in early metastatic prostate cancer based on the assessment of biomarkers in cancer tissue samples and circulating tumour cells.

In this study, the investigators aim to determine if the Vienna nomogram increases the detection rate of TRUS-guided prostate biopsies by conducting a prospective randomized study comparing the Vienna nomogram with a 10-core biopsy protocol.

The objective of the study is to assess the design features of a modified stainless steel access needle (single use disposable) in a clinical setting and a disposable, single use, custom-made, polymer needle guide used in conjunction with a rectal ultrasound probe. The disposable stainless steel access needle may be used with or without the disposable needle guide, but will always be used with ultrasound image guidance and a biopsy gun. The primary purpose of the single-use disposable access needle is to guide the use of a biopsy gun to obtain a tissue sample from the patient's prostate gland through a percutaneous puncture of the perineum. The primary purpose of the disposable needle guide is to stabilize the needle biopsy and better approximate the most direct path to the prostate.

Inclusion criteria: Patients with biochemical recurrence (Phoenix criteria: PSA nadir + 2 ng/ml) after radiation therapy for prostate cancer addressed for prostate biopsy OR Patients referred to our institution for biopsy-proven local recurrence after radiation therapy for prostate cancer but needing a re-assessment with biopsy (insufficient number of biopsy and/or imprecise location of positive biopsy and/or questionable diagnostic of recurrence) Study Design: Included patients will undergo an endorectal US examination with a Histoscanning™ acquisition and a multiparametric (T2-weighted, diffusion-weighted and dynamic contrast-enhanced) MRI. Two independent operators will separately define suspicious focal lesion on Histoscanning™ images and on MR images. Random biopsies (at least 2 cores) will be performed in sextants negative at Histoscanning™ and at MRI ; In sextants positive at Histoscanning™ and/or at MRI, targeted biopsies will be performed in the suspicious part of the sextant (at least two cores per suspicious lesion). Histoscanning™ and MRI results will be compared to biopsy results. A total of 30 patients will be included

The present Phase II study aims to assess the rates of late rectal toxicities of grade ≥ 2 after hypofractionated radiotherapy of prostate cancer of 62 Gy in 20 fractions of 3.1 Gy with an injection of hyaluronic acid (HA) in the space between the rectum and the prostate. Thirty-six patients with a low- to intermediate-risk prostate cancer according to the D'Amico classification are included in the present protocol. The main characteristics of the study are that the patients benefit of a reduction of the treatment duration from 40 to 20 fractions, due to the hypofractionated irradiation, and of an injection of 3 to 10 cc of hyaluronic acid in the perirectal fat between the rectum and the prostate.

The study includes the recruitment of patients with advanced prostate cancer resistant to chemical castration This is a multicenter prospective trial randomized phase III

The purpose of this study is to compare the toxicity of two new radiation schedules for the treatment of prostate cancer. Patients will be randomized to receive 5 treatments delivered every other day over 11 days, or once per week over 29 days. Both of these schedules are shorter than the standard treatment which is usually 39 treatments over 8 weeks.

National multicentric prospective open study, comparing two current surgical methods: laparoscopic way versus open retropubic way among patients requiring a radical prostatectomy for a localised prostate cancer.

Positron emission tomography using carbon-11 acetate (AC-PET) may help find local or distant metastases from prostate cancer. This clinical trial is studying how this imaging test may help influence the choice and extent of initial treatments, and subsequent treatments.
