Active clinical trials for "Prostatic Neoplasms"

Prostate cancer has been the most common neoplastic disease in men in Finland over the last ten years. Prostate-specific antigen (PSA) plays an important role in screening of prostate cancer. However, PSA has a limited sensitivity and specificity for prostate cancer detection. Commonly, the diagnosis of prostate cancer is done by transrectal ultrasonography (TRUS) guided biopsy. Because of the low accuracy of TRUS a systematic biopsy is usually performed instead of targeted TRUS biopsy. As biopsy carries a significant risk of complications, there is an increasing interest in developing more accurate non-invasive imaging modalities. This prospective multi-institutional study will enroll 400 men with clinical suspicion of prostate cancer due to higher serum level of PSA than 2.5 ng/ml and/or abnormal digital rectal examination. Anatomical magnetic resonance imaging (MRI) and diffusion weighted imaging (DWI) at 1.5/3 Tesla (T) magnetic field using surface coils will be used to non-invasively predict the presence or absence of prostate cancer. Targeted TRUS guided biopsy based on MRI findings will be performed in addition to routine twelve core TRUS biopsy. Moreover, selected serum and urine biomarkers as well as biomarkers extracted from fresh biopsy sample will be collected and correlated with the presence or absence of prostate cancer.

The aim of the present phase III study is two-folded: 1) to show a superiority of external beam radiotherapy combined with a brachytherapy boost versus exclusive external beam radiotherapy and 2) to evaluate the economic impact of each treatment. The study includes 33 cancer centres, the inclusion time is of 2 years and the follow-up is of 5 years.

This study will assess the impact of the novel oral hormonal agents (abiraterone acetate or enzalutamide) among elderly metastatic prostate cancer patients. This study will assess the influence of treatments on patients' cognitive functions on a longitudinal basis and evaluate the quality of life and the adherence of patients who had or develop cognitive disorders.

The purpose of this study is to evaluate the effort and resources (incl. costs) required to detect 20 clinically relevant prostate cancer (PCA) in a screening program based on bpMRI of the prostate.

STHLM3 is a paired diagnostic trial aiming to assess whether a panel of biomarkers for prostate cancer can substantially reduce the proportion of men referred to biopsy whilst maintaining sensitivity for aggressive prostate cancer

The principal aim of this study is to determine if PET/MRI imaging with 18-F fluciclovine (Axumin) identifies those men with false negative MRI fusion targeted biopsy (MRFTB) of PI-RADS 4 and 5 lesions. PI-RADS 4 and 5 MRI lesions are highly suspicious for clinically significant prostate cancer and require future repeat MRI imaging and possible repeat prostate biopsy depending on the results of the repeat MRI. Men, who had negative MRFTB within past 12 months of PI- RADS 4 or 5 MRI lesion will be included in this diagnostic study. The repeat MRI is standard of care at NYU Langone Health. The investigation aspect of the study is to perform an Axumin scan the same day as the MRI. Those men with persistent highly suspicious lesions will under MRFTB. The biopsy results will be compared with intensity of Axumin uptake within the prostate. The urologist will have the discretion to biopsy Axumin avid lesions not detected by MRI.

The promoter propose a pilot study evaluating the feasability of robot-assisted radical prostatectomy on outpatient in patients with localized prostate cancer. This study will enrole a total of 20 patients over one center, followed for 1 month. The total study duration will be 15 months, including statistical analysis and publication.

This pilot clinical trial studies how well gallium Ga 68-DOTATATE positron emission tomography (PET)/computed tomography (CT) works in treating patients with castration resistant prostate cancer that has spread to other placed in the body. Gallium Ga 68-DOTATATE PET/CT may help doctors to identify those patients with early neuroendocrine transdifferentiation and who are at greater risk for poor outcomes.

68Ga-HBED-CC-PSMA is a radiopharmaceutical allowing a new imaging modality for the detection of prostate cancer recurrences, used in recent years in clinical studies by some teams mainly in Europe (1-6 ). The aim of this study is to study the diagnostic performance of 68Ga-HBED-PSMA PET / CT in occult recurrent carcinoma (PCa) by prospectively comparing it to the standard techniques used in this indication: optimized bone scintigraphy with double TEMP / CT systematic and abdominopelvic MRI. The therapeutic impact and tolerance of this examination will also be evaluated. The expected results are a demonstration of the superiority of 68Ga-HBED-PSMA PET compared to the standard assessment, with a potential impact on the therapeutic management of patients

A promising imaging technique involving new prostate specific membrane antigen (PSMA) positron emission tomography (PET) tracers is emerging in metastatic prostate cancer (PCa). This approach has demonstrated higher sensitivity in detecting metastases, prior to and during therapy, than current imaging standard of care (CT and bone scan). PSMA is expressed in the vast majority of PCa tissue specimens and its degree of expression correlates with a number of important metrics of PCa tumor aggressiveness. [18F]DCFPyL is a promising high-sensitivity second generation PSMA-targeted urea-based PET probe. Studies employing second-generation PSMA PET/CT imaging in men with biochemical progression after definitive therapy suggest detection of metastases in over 60% of men imaged. In fact, PSMA-based PET has so far proven to have higher sensitivity than any other modality for localization of the site of recurrence. Applications that show promise and require further investigation include the characterization and risk stratification of primary PCa, complete staging of metastatic PCa to allow for PSMA-targeted radiotherapy and improved identification of patients with oligometastatic disease. The objective of this study is to explore the detection yield of PSMA-PET in a pilot cohort of patients at CHUM and establish the repeatability of the technique before investigating it more widely.
