Active clinical trials for "Prostatic Neoplasms"

Although brachytherapy toxicity data on erectile dysfunction, urethral dysfunction and bladder and bowel impact has been collected for a number of years, there is limited information on its effect on male fertility. This study aims to investigate the effect of brachytherapy on fertility

The initial staging of locally advanced prostate cancer is made with Computed Tomography scan (CT), Magnetic Resonance Imaging (MRI), and bone scan (BS). For this type of cancer, reference treatment is radiotherapy combined with hormone therapy. The added value of MRI in the delineation of volumes for radiotherapy is known, especially for the definition of extra-prostatic extensions and prostatic apex. However, its regular use is difficult. Indeed, acquisition of Magnetic Resonance Imaging parameters for diagnostic are not adapted to be fused with the planning Computed Tomography. The literature shows that Positron Emission Tomography-Computed Tomography with Fluorocholine is better in terms of diagnostic performance compared to bone scan for bone metastases and to pelvic Magnetic Resonance Imaging for nodal extension. It would therefore improve staging for these patients with a high risk of locoregional and metastatic invasion even if its use is currently not recommended in the initial staging. Thanks to Magnetic Resonance Imaging acquisition parameters adapted to Radiotherapy and additional functional information, an acquisition in tri-modality Positron Emission Tomography/computed Tomography/ Magnetic Resonance Imaging could have an impact on the volumes definition for radiotherapy or even on the therapeutic strategy. The aim of the study is to evaluate the volume modifications obtained on the trimodality evaluation, compared to the standard initial staging (geometric comparison). In addition, it would be a preliminary study for a project using Prostate-specific membrane antigen (PSMA) in trimodality, and / or for a therapeutic interventional study.

Kidney transplantation is considered the standard of care for patients with end-stage kidney disease under chronic dialysis treatment. Today, modern surgical techniques have dramatically improved the quality of life and the overall survival of renal transplant recipients (RTRs) . Besides, the use of novel immunosuppressors have increased the 1-year graft survival rate and decreased acute rejection rate . Unfortunately, several transplantation-related diseases including cancer, cardiovascular disease and infection may affect the survival of renal transplant recipients. It has been estimated that RTRs are 2- to 5- fold more likely to develop cancer compared to the general population. Therefore, the development of cancer has become a major concern as it is currently one of the main causes of death in RTRs. The increasing incidence of post-transplant malignancies is generally attributed to immunosuppression which leads to impaired immunosurveillance of cancer cells and virals infections capable of cancer development. Additionally, it has been observed a direct and specific pro-oncogenic effect on RTRs of immunosuppressive drugs and other immunosuppression-independent factors such as the increased age of RTRs, the male gender and the pre-transplant dialysis duration . Prostate cancer is the second most diagnosed cancer in men and the most common non-skin solid neoplasm in RTRs. Generally, the vast majority of post kidney transplantation prostate cancers are localised; however, due to the lack of randomized studies, no specific guidelines for the management of localized prostate cancer are available and, consequently, RTR patients are being treated with surgery or radiotherapy according to national or local guidelines. The concomitant use of immunosuppressors and the presence of the kidney graft in the pelvic cavity make the treatment of localised prostate cancer post kidney transplantation more challenging, highlighting the need for these patients to be addressed to urological oncology centres with surgeons familiar with oncological and transplant surgery. Prostate cancer is the second most diagnosed cancer in men and the most common non-skin solid neoplasm in RTRs, however, little studies describe the real incidence of prostate cancer in RTRs. The aim of this study is to retrospectively review a 25-year experience at the Florence Transplant Center in order to evaluate the incidence of prostate cancer and its possible clinical/pathological factors able to influence the survival.

The general aim of the study is to describe the use of elective pelvic node irradiation (ENI) in Italy, in patients with intermediate/high/very high-risk prostate cancer patients submitted to adjuvant or radical Radiation Therapy (RT) with or without concomitant Androgen Deprivation hormone Therapy (ADT). The study aims at the definition of survival, toxicity and QoL data in a representative sample of intermediate, high and very high risk prostate cancer patients consecutively recruited in Italian Radiation Oncology Center over two years.

PROSABI is a prospective multicentre observational study in metastatic Castration-Resistant Prostate Cancer (mCRPC), designed to explore prognostic biomarkers in patients undergoing treatment with abiraterone

To assess patient preference between ODM-201 and enzalutamide by patient preference questionnaire

To evaluate the use of the CAMbridge PROstate Biopsy devicE (CAMPROBE) as a method of undertaking prostate biopsy as part of their clinical management.

A single arm phase II study of prostate motion for prostate cancer to primarily compare prostate motion between different treatment duration for IMRT and VMAT.

This project is about the detection of occult tumor cells in surgical margins of radical prostatovesiculectomy by analysing the methylation status of Glutathione S-transferase P 1 (GSTP1). After gland excision specimens are obtained from 9 defined areas of the prostatic fossa. The biopsies are divided into two parts. One part used for histopathological analysis and the other part for moleculargenetic analysis. Results will be correlated e.g. with tumor stage, Gleason Score and prostate specific antigen (PSA). The prostate-cancer-negative control group with bladder cancer.

Prostate cancer is a common disease in men. In prostate 35% of biopsies, usually done due to increased PSA levels or clinical suspicion, are false negative, despite malignancy. Multi-parametric prostate MRI detects malignant neoplasm lesions better than other imaging devices. A sonar-guided prostate biopsy based on multi-parametric MRI images improves detection of malignancy. Ga68 PSMA-PET test uses a radioactive marker that binds to the prostate's cells and is shown to be a primary prostate tumor site in addition to metastasis. We believe that the combination of measures from a single Ga68 PSMA and multi-parametric MRI test can lead to further improvement in malignancy, better biopsy guidance, and optimal treatment for the patient.
