Active clinical trials for "Prostatic Neoplasms"

The goal of this observational study is to establish an evaluation system for accurate identification of prostate cancer and prostatic hyperplasia in patients in the PSA gray zone. The main questions it aims to answer are: proportion of men who could have avoided biopsy with positive PSMA-PET and no clinically significant cancer detected on biopsy; develop a nomogram of biomarkers (PSA) + imaging (PSMA) to predict the likelihood of clinically significant prostate cancer in men pre-biopsy. Participants will: 1. undergo PSMA PET/CT and multiparameter MRI; 2. undergo biopsy; and 3. undergo radical prostatectomy for biopsy-proven clinically significant prostate cancer. Researchers will compare the PSMA PET/CT-based features between prostate cancer and benign prostatic hyperplasia to see if there are differences in semiquantitative parameters.

The purpose of this study is to assess the real-world outcomes differences between apalutamide or enzalutamide plus androgen deprivation therapy (ADT) for the treatment of participants with metastatic hormone-sensitive prostate cancer (mHSPC).

The diagnostic tools for detecting patients with early prostate cancer are limited due to poor diagnostic performance. The positron emission tomography (PET) combination with the diagnostic radiopharmacy is a non-invasive tool to provide the molecular imaging of the whole body and offer more comprehensive physiological information and then can raise the diagnostic performance. Prostate-specific membrane antigen (PSMA)-targeting pharmaceuticals have been regarded as the most promising diagnostic tool to diagnose patients with prostate cancer. Currently, the 18F-PSMA-1007 as PSMA-targeting 18F-radiolabeled pharmaceuticals have developed and successfully used in patients with intermittent- and high-risk prostate cancer or recurrent prostate cancer. The study aims to understand the diagnostic performance of 18F-PSMA-1007 PET/CT in different-stage prostate cancer patients by initiating the first multicenter clinical trial of 18F-PSMA-1007 in Taiwan.

The purpose of this study is to collect prostate cancer tissue from males with metastatic prostate cancers in order to study the tumor microenvironment (TME), which is the area surrounding the tumor including cells, blood vessels, etc., in men with metastatic prostate cancer. The type of research performed on these tissue samples include genetic & molecular analyses.

This study collects blood and tissue samples from patients with cancer and without cancer to evaluate tests for early cancer detection. Collecting and storing samples of blood and tissue from patients with and without cancer to study in the laboratory may help researchers develop tests for the early detection of cancers.

Multispectral imaging of the lymphatic draining pattern of the tumor and the abdominall wall/lower limb to evaluate technical feasibility to differentiate these patterns and in the future reduce the amount of complications that result from damage to lymphatic structures.

Before prostate puncture, the patient's serum was collected for PHI detection, and multi-parameter MRI was performed to obtain the PI-RADS score. The sensitivity and specificity of PHI combined with PI-RADS score in the diagnosis of clinically significant prostate cancer were explored.

Prior to treatment, it is essential to assess not only the extent of prostate cancer within the prostate, but also to determine whether the disease has initiated metastatic spread. Whole-body MRI has become a viable option for the detection of metastatic disease derived from a number of cancers, but is typically performed in a separate scanning session to an initial dedicated prostate MRI in which the local disease is assessed. In patients known to be at high risk for significant prostate cancer prior to this initial MRI, and thus highly likely to proceed to treatment, this delays arriving at a definitive treatment decision. The investigators will evaluate the sensitivity of a protocol that combines bi-parametric prostate MRI, performed according to PI-RADS v2.1 guidelines, with a whole-body MRI based on the METastasis Reporting and Data System for Prostate Cancer (MET-RADS-P) guidelines, for an All-in-One, local and systemic staging of intermediate-favorable or high risk prostate cancer patients. The resulting staging decisions will be compared to the results of systemic staging with those obtained by computed tomography and bone scintigraphy in the standard staging pathway.

The benefit of dose escalation in radiotherapy (RT) for biochemical control of prostate cancer is a clearly established fact based on the results of different published prospective trials. This benefit, acquired with three-dimensional conformal radiation technique is counterbalanced by an increase in urinary and gastrointestinal toxicity. The joint progress of dose planning systems and multileaf collimators (MLC) technology have enabled the Intensity Modulated Radiation Therapy (IMRT). Recently the contribution of "spacers" positioned in the septum between the rectum and the prostate could improve the functional results of IMRT in terms of rectal toxicity. The aim of the investigators study is to assess the dosimetric gain from the contribution of the implantable BioProtect balloon on organs at risk.

The investigators hypothesize that this single-cell analysis can be used to evaluate prostate needle-core biopsies prospectively even in non-homogenous samples by providing profiles of proteomic and phenotypic signatures. These profiles will in turn enable better predictions of the malignant progression of prostate cancers in the settings of current clinical practice.
