Active clinical trials for "Prostatic Neoplasms"

To determine if fBT+sRT is superior to standard care in terms of urinary toxicity by having fewer patients experience a minimal important decline (MID) in urinary irritation/obstructive QoL

This trial will evaluate whether the following aspect of surgical technique influence outcome: Lymph node dissection. In some patients, scans taken before surgery show that a lymph node has cancer. Surgeons make sure to remove those affect lymph nodes and all other lymph nodes in the area. However, it is not known whether removing lymph nodes helps prostate cancer patients whose scans do not show positive nodes. In this study, patients with clear scans will either receive a lymph node dissection or not."

Stereotactic Ablative Radiation (SABR/SBRT) will be prescribed to a dose of 35 Gy in 5 fractions, once weekly to prostate with a simultaneous intra-prostatic boost to the MR detected nodule up to 50Gy. The pelvic lymph nodes and seminal vesicles will also receive 25 Gy in 5 weekly fractions.

An extended pelvic lymph node dissection (ePLND) is the most accurate staging method to assess the presence of lymph node metastases in prostate cancer (PCa) patients. The therapeutic value, however remains unclear. Prospective randomized trials to address this void are lacking. Since in intermediate and a proportion of high risk PCa the risk of nodal metastases is generally below 25%, the vast majority of men undergo a procedure that has no oncological benefit, but is not without toxicity. Therefore, the investigators aim to compare the oncologic outcomes of intermediate- and high-risk PCa patients with an estimated risk of lymph node invasion of 5-20% undergoing a radical prostatectomy (RP) with or without an ePLND.

To clarify the role of short-term Androgen deprivation therapy (ADT) in the context of intermediate unfavorable and a subclass of high-risk patients treated with prostate Stereotactic radiotherapy (SRT). In intermediate unfavorable risk group, when choosing standard external beam radiotherapy, short term ADT is superior in terms of biochemical disease free survival (bDFS) to EBRT alone. In high risk disease, results of the combination therapy are even more clear. Prostate SRT has been endorsed as option for primary radical treatment for prostate cancer. In such patients, the benefit of ADT is still unknown and the decision is left to clinical judgement. For these reasons, it seems to be relevant to propose a randomized, open label, phase III clinical trial of prostate SBRT + 6 months ADT versus prostate SBRT alone in intermediate unfavorable and a subgroup of high risk prostate cancer patients.

According to the guidelines of the European Association of Urology (EAU), the first-line treatment for newly diagnosed mPC consists of immediate castration with the addition of docetaxel or abiraterone acetate. As seen in other well-known solid tumours - such as ovarian, colon and renal cancer - local treatment (LT) of the primary tumour could lead to a survival benefit compared to standard of care (SOC). Several retrospective studies have suggested a survival benefit of local treatment of the primary tumour with SOC versus SOC only in mPC. These patients also have less local symptoms of their disease, which has a major impact on quality of life (QoL). Several prospective studies have already been set up to compare either surgery or radiotherapy with the SOC. In expectation of their results and because randomization seems challenging, the investigators want to set up a trial to evaluate the feasibility of randomization between both local treatment groups.

This study is being proposed to evaluate the use of moderate hypofractionated proton therapy in low and intermediate risk prostate cancer patients. Quality of life outcomes as well as gastrointestinal and genitourinary early and late toxicities will be analyzed and compared to conventional proton therapy regimens. It is thought that this regimen will produce comparable findings and would result in substantial health care cost savings, as well as, be more convenient for patients.

This is a prospective study to determine if the adjuvant use of Curcumin improves recurrence-free survival.

This trial studies how well resistance training with or without creatine monohydrate supplement works in improving body composition and health outcomes in patients with prostate cancer that has spread to other places in the body. Resistance training, with or without creatine monohydrate supplement, may help to improve feelings of tiredness and overall physical function in patients with prostate cancer.

Hypofractionated radiosurgery has been investigated in a few trials and appears to be safe and feasible. Investigators initiated this multicenter phase II prospective trial to analyse feasibility (toxicity) of hypofractionated radiosurgery with 5 fractions in patients with localised prostate cancer under the hypothesis that the ratio of patients with late toxicity ≥ grade 2 after 3 years amounts 4.1% and is significant lower than 12.3% and 8.7% currently.
