Active clinical trials for "Prostatic Neoplasms"

The role of this study is to focus on the potential role of abiraterone acetate in treatment-naive patients newly diagnosed with high-risk localised prostate cancer requiring combined hormonal therapy and radiotherapy.

The purpose of the present study is to investigate if endurance training can be used as a therapeutic action against the adverse metabolic disturbances and unfavourable changes in body composition that accompany the androgen deprivation therapy (ADT) treatment in prostate cancer patients.

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.

This Phase 3 study has been designed to confirm that adding custirsen to cabazitaxel/prednisone treatment can slow tumor progression and enhance survival outcomes compared to standard cabazitaxel/prednisone treatment in men with metastatic castrate resistant prostate cancer (CRPC). This will be a randomized, open-label, multicenter, international trial. Treatment will consist of cabazitaxel/prednisone/custirsen vs. cabazitaxel/prednisone. A total of approximately 630 patients will be randomized with equal probability to the two arms.

The objective of the study is to evaluate 68Ga PSMA 11 PET/MRI and 68Ga RM2 PET/MRI for biopsy guidance in patients with suspected prostate cancer.

Prostate cancer patients have a number of excellent treatment options to consider, and quality of life following treatment is often a consideration in treatment choice. One critical quality of life concern for patients diagnosed with prostate cancer is sexual function. Previous studies point to a vascular mechanism of impotence post-radiation therapy, as opposed to a nerve-based mechanism following surgery. In this study, the critical vascular structures (internal pudendal artery and corpus cavernosum) are defined by MRI-based imaging and included in treatment planning for radiation treatments, hopefully preserving critical artery function. This study will collect erectile function preservation rates at 5-years post-vessel-sparing radiotherapy with or without aids using the patient reported using the simplified three-question erectile function scale.

Focused stereotactic radiation treatment of localized prostatic adenocarcinoma. in order to quantify the delay between the focused treatment and the salvage procedure.

The purposes of this study are: a) to develop a statewide Biobank for prostate cancer among men of African Ancestry in Florida and; b) to examine whether smoking increases the aggressiveness of prostate cancer using several biological approaches. Investigators plan to contact African American prostate cancer patients regarding participation. This project has 3 main components. Eligible patients may choose to participate in any or all parts of the study: Questionnaires; Saliva Samples; Tumor Tissue.

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.

Radiation is delivered to the prostate and seminal vesicles in 5 treatment sessions (fractions). Doses ranging from 35-45 Gy in 5 fractions have demonstrated good outcomes with acceptable toxicity.
