Active clinical trials for "Prostatic Neoplasms"

Most prostate cancer treatment research in the last decade has been focused on trying to improve quality of life, while maintaining a high level of cancer control. However, the concept of Focal treatment is proposed as an intermediate option between active surveillance and treatment of the whole prostate. Focal ablation aims to efficiently treat the localized cancer while reducing complications related to standard treatments, including the risks of incontinence and impotence. Focal Irreversible Electroporation (IRE) delivered by NanoKnife System is composed of the NanoKnife Generator and NanoKnife Single Electrode Probes. With IRE, an electrical current is delivered between a pair of probes in a series of pulses. These pulses create irreversible pores in cell membranes and lead to cell death which allow for only the tissue between these probes being destroyed. The aim of this study is to analyze the safety and efficacy of transperineal IRE treatments in intermediate risk anteriorly localized prostate cancer patients.

This serves as a registration trial. It aims to record short, intermediate, and long-term outcomes of patients treated with targeted laser ablation of biopsy confirmed prostate cancer. Outcomes will be categorized as: 1- Procedure Related, 2- Perioperative - Adverse Events that may occur within 90 days, 3-Oncologic: Recurrence of cancer in treatment area, de-novo tumors, conversion to radical surgery, radiation or cryoablation, emergence of metastasis, 4- Functional: Sexual and Urinary function following treatment

Radiotherapy (RT) is an established treatment option for localized prostate cancer (PCa), with cure rates similar to those of radical prostatectomy. In the last decade, conventionally fractionated RT (1.8-2.0 Gy per fraction to 78-80 Gy) has been replaced by moderately hypofractionated RT (2.3-3.65 Gy per fraction to 56-70 Gy). The rationale behind this change is the scientific level 1 evidence that a higher dose per fraction may improve the cost-benefit of RT due to the specific radiobiology of PCa (a lower alpha/beta than that of adjacent healthy tissues). Additionally, there is a practical advantage both for patients and the radiation department due to a reduced number of fractions. More recently, extreme hypofractionation or stereotactic body radiotherapy (SBRT) (7-9.5 Gy per fraction to 36-43 Gy in 4-7 fractions) has been introduced as RT modality, and proved to be an effective and safe treatment option for patients with low and intermediate clinically-localized PCa, with similar incidence of late toxicity and 5-year disease free survival outcomes when compared to hypofractionated and conventional radiotherapy regimens. International guidelines endorse extreme hypofractionated SBRT as routine treatment option for low and intermediate risk PCa patients. For high-risk prostate cancer, preliminary results of ongoing prospective studies are promising, but these data are not yet mature enough to recommend extreme hypofractionated SBRT in high-risk prostate cancer. Upon this, ongoing prospective trials handle strict eligibility criteria hereby selecting patients with few comorbidities. This may not necessarily fully reflect the real life patient population. Indeed, patients with a large prostate size, a history of transurethral resection of the prostate (TURP), or 'significant' urinary baseline symptoms may be at risk for experiencing increased toxicity. Based on this concern, these patients were excluded from ongoing clinical trials. However, whether these patients will really develop more toxicity, is a theoretical concern, not yet based on clinical evidence. It is our hypothesis that using modern radiotherapy such as volumetric arc therapy (VMAT) and image-guided radiotherapy (IGRT) - both standard technologies at the Radiation-Oncology department in Leuven University Hospitals - extreme hypofractionated SBRT can be successfully implemented in the treatment of intermediate risk and a select group of high-risk PCa patients and/or patients with pre-existing urinary morbidity.

GENPROS aims to analyse the outcomes of patients with rare gene mutations in the cancer predisposition genes, BRCA1, BRCA2, HOXB13, and Lynch Syndrome, after a diagnosis of and treatment for prostate cancer (PCa). The study includes a cohort of gene mutation carriers with PCa matched with a control group of men with PCa who are known not to carry a mutation in the same gene. Clinical data regarding treatment and patient outcome will be collected retrospectively and prospectively. Archived tumour samples will also be collected for tumour profiling. A blood or saliva sample will be taken, if the participant consents to this part of the study, for genetic profiling to investigate any association of other inherited factors with PCa outcomes. Information obtained from this study will be of critical importance to support clinical trials investigating the most appropriate management of PCa in this group of patients at increased risk of prostate cancer.

Registration of Prostate Cancer patients undergoing Prostate Cryotherapy guided by Mutiparametric-MRI (MP-MRI) highlighting biopsy confirmed regions. The primary outcome measure is 5 year oncological control. Secondary aim is lack of progression beyond the prostate gland. The aim of intervention is to eradicate prostate cancer disease in the treated area while imposing no or minimal deleterious effects in quality of life.

Imaging and staging of prostate cancer is critical for surgical and treatment planning. In this protocol we will image patients with suspected metastatic prostate cancer using 11C-Choline PET and Gallium-68 labeled HBED-CC PSMA (more commonly called 68Ga-PSMA-11) or F-18 labeled PSMA 1007 in order to demonstrate their utility in detecting prostate cancer.

The purpose of this study is to find out in the real-world setting, if darolutamide is safe and effective for patients diagnosed with prostate cancer that has not spread to other parts of the body. When a patient is enrolled to the study, his/her physician would have already made the decision to treat patient with darolutamide per local standard practice.

This study will evaluate whether a lifestyle intervention focused on weight loss, EMPOWER, reduces prostate cancer progression at 12 months among men with biochemical recurrence following local treatment for prostate cancer. Half of the men will be randomized to receive the EMPOWER intervention, while the other half will receive standard of care.

Prostate cancer (PCa) is the most frequently diagnosed cancer in men and second leading cause of cancer-related death. Men with PCa have a wide range of possible outcomes if the cancer has not spread and is classified as Intermediate-Risk PCa (IR-PCa). The standard treatment for IR-PCa is radiation therapy (RT) with or without hormone therapy which can result in cure in some men. In other men, the cancer can come back or spread to other areas of the body. Treatment response in men with IR-PCa is highly variable. This uncertainty has led to significant under- and over-treatment. This study aims to find out if the addition of intensive treatment (hormonal therapy: darolutamide + degarelix) to standard treatment for PCa will work better than standard treatment alone. To do this, some participants will receive hormone therapy and others will not. All participants will receive RT. Currently, it is difficult to identify men who may require more intensive therapy. Current methods, such as using prostate specific antigen (PSA) alone, may not give the doctor enough information about who requires more intensive treatment. The researchers conducting this study believe that a particular arrangement of cancer cells [called intraductal carcinoma (IDC)] and the presence of a genetic marker called SChLAP1 can be used to identify people who would benefit from more intensive therapy. Hormonal therapy such as with drugs called darolutamide (new drug for PCa) and Degarelix, reduce androgens (male hormones, such as testosterone) or block their effect on the cells. PCa cells require androgens to grow and divide, so removal of androgens may be effective in preventing the return of cancer following radiation therapy. Although darolutamide has been studied in about 1000 men with PCa and seems promising and well tolerated it is considered an experimental drug, therefore it can only be used in a research study such as this one. Degarelix has been approved by Health Canada to treat PCa. This is a phase 2, open label, randomized, controlled study and will be conducted across sites in Canada. To qualify, men must have IR-PCa and have both SChLAP1 and IDC present or both absent. Participants will be randomized to receive RT with hormone therapy or RT only. The study treatment period is 6 months for the RT + hormone therapy group. RT will take about 1-2 weeks. All participants will be followed for 5 years with multiple visits to assess safety and treatment effects.

Prostate cancer is the most common cancer in France (54,000 cases in 2011). About 20,000 radical prostatectomies (PR) per year are performed. Despite the progress of PR over the past 20 years, the rate of erectile dysfunction post PR varies between 30 and 90% and only 16% of operated men recover their pre-treatment erections. There is currently no validated post-prostatectomy rehabilitation protocol. The associations of patients, including the National Association of Prostate Cancer Patients have a very strong demand for treatment of sexual problems after treatment.
