Active clinical trials for "Prostatic Neoplasms"

To prospectively evaluate the radiodrug biodistribution of a novel PET imaging agent [68Ga]Ga-PSMA-D5 in different organs of prostate cancer patients and its diagnostic efficacy in the diagnosis, recurrence and metastasis of prostate cancer, and to compare with [68Ga]Ga-PSMA-11.

The study is a non-randomized, prospective trial of men scheduled for radical prostatectomy for treatment of prostate cancer as standard of care and will undergo a series of pre-operative multi-modality imaging studies. Pre-operative imaging will be correlated with actual pathology results and statistical modeling performed to determine the most informative imaging biomarkers in predicting cancer location and aggressiveness (Gleason Score).

This study will enroll 60 patients previously enrolled to MCC#18523, "A Validation Study on the Impact of Decipher® Testing on Treatment Recommendations in African-American and Non-African American Men with Prostate Cancer: (VANDAAM)" that had high risk Decipher test results (Decipher score >0.45). Patients with a high genomic classifier (GC) score at diagnosis will be approached for formal consenting for PSMA-PET imaging at 2 years post treatment.

The current study aims to examine the hypothesis that combining the focal effects of HIFU with the systemic effects of androgen deprivation therapy might eradicate the prostatic cancer cells by targeting the 'visible' index focus (by HIFU) and the tumour surrounding microenvironment which may contain 'invisible' foci and aberrant PCa related signalling (by androgen deprivation therapy) to enhance oncological outcomes of HIFU hemi-ablation in men with localized PCa, and consequently reducing treatment failures.

The purpose of this study is to evaluate if a diet with a high content of phytoestrogens can slow down the prostate tumor proliferation. Phytoestrogens are found in food items such as soy, rye, and seeds. Two hundred thirty men with prostate cancer will be included in the study and followed until surgery (at least 6 weeks). Half of the study participants will receive general information about healthy food choices and a package of foods with high content of phytoestrogens to add to their food. The other half will get the same information but not receive the food-package.

This is a study of the Wolverhampton Assessment Tool (WATapp), a five-item questionnaire for patients with advanced or metastatic prostate cancer to say how they feel normally in terms of pain, urinary frequency, eating, and tiredness. It is widely recognised that patient-reported outcomes give a measure of overall effect of clinicians' actions on patients and that they can be used to guide the management of the patient's condition. WATapp is designed to reduce the need for the patient to attend hospital so much for routine follow-up consultations (an important aspect in light of COVID-19), to give the patient some sense of agency and control and to inform his clinician of just he feels he is coping with his treatment. Now the investigators want to find out just how the results from WATapp correspond to, for example, changes in the patient's PSA, testosterone or other blood results which are routinely measured; and to find out how patients and clinicians feel about using WATapp. Men with advanced or metastatic prostate cancer will be eligible to take part in the study and participation is in addition to whatever treatment they are on. Clinicians who choose to offer WATapp to their patients will also be invited to take part and they will be asked to share with the researchers anonymised, linked patient data and scores from WATapp.

This phase II trial studies how well green tea catechins work in preventing progression of prostate cancer from a low risk stage to higher risk stages in men who are on active surveillance. Green tea catechins may stabilize prostate cancer and lower the chance of prostate growing.

The investigators hypothesize that an increase in dietary fiber intake during radiation therapy may provide better long-term intestinal health for the cancer survivor. If the hypothesis is not correct, the increased intake may only mean an increase in acute side effects. All participants are advised to consume at least 16 g of dietary fiber/day via food. In addition, participants are invited to take capsules that together contain either 5.5 g of dietary fiber from psyllium husk or placebo.

Researchers think that exercise may be able to prevent cancer from coming back by lowering ctDNA levels. The purpose of this study is to explore how aerobic exercise (exercise that stimulates and strengthens the heart and lungs and improves the body's use of oxygen) can reduce the level of ctDNA found in the blood. During the study, the highest level of exercise that is practical, is safe, and has positive effects on the body that may prevent the return of cancer (including a decrease in ctDNA levels) will be found. Each level of exercise tested will be a certain number of minutes each week. Once the best level of exercise is found, it will be tested further in a new group of participants. All participants in this study will have been previously treated for breast, prostate, or colorectal cancer.

The purpose of this study is to evaluate the diagnostic performance of [18F]CTT1057 as a PET imaging agent for detection and localization of PSMA positive tumors using histopathology as Standard of Truth (SoT). Tissue specimens from both the primary tumor and pelvic lymph nodes dissected during surgery from patients with newly-diagnosed high-risk prostate cancer (PCa) will be used for the histopathology assessments. Approximately 195 participants will be enrolled to ensure that at least 156 participants are evaluable (i.e. have both an evaluable PET/CT scan and histopathology assessment and have not received any prohibited systemic antineoplastic therapy before the completion of PET/CT and surgery), which will be required for the calculation of the co-primary endpoints.
