Filter by:This phase II trial studies how well atezolizumab works alone or in combination with etrumadenant or tocilizumab in treating men with localized prostate cancer before radical prostatectomy. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Androgens can cause the growth of prostate cancer cells. IL-6 is expressed by prostate cancer and within the tumor microenvironment and shown to enhance prostate cancer and disease progression. Treatment with an anti-IL-6 antibody such as tocilizumab may inhibit cancer progression. Giving atezolizumab in combination with etrumadenant or tocilizumab may work better in treating prostate cancer.
Magnetic resonance imaging (MRI) has improved detection of clinically significant prostate cancer (PCa). MRI-guided transurethral ultrasound ablation (MRI-TULSA) system incorporates precise diagnosis and simultaneous ablation of prostate tissue enabling lesion-targeted treatment of PCa. Lesion-based treatment strategy spares surrounding healthy tissues from injury, which may improve the outcome of genitourinary function. This study further investigates the safety and the efficacy of lesion-targeted ablation of MRI-visible biopsy-proven PCa with MRI-TULSA.
Single center, single-arm, open-label, 60-month follow-up phase IIb clinical trial. Men with localized prostate cancer will receive TOOKAD® Soluble VTP under general anesthesia. To evaluate the absence of biopsy detectable Gleason grade 4 or 5 prostate cancer tumors anywhere in the prostate gland on 12-month, post-treatment biopsy following TOOKAD® Soluble-VTP in men with prostate cancer Gleason score 7(3+4).
Focal treatment of localized prostate cancer aims to destroy the cancerous foci without damaging surrounding tissues to avoid the side effects of radical treatments. This is why focal treatment is positioned as an alternative to radical surgery as well as an alternative to active surveillance. This study is a feasibility study. It aims at treating the index tumor (the most aggressive one) which determines the vital prognosis of patient, while preserving the maximum surrounding prostatic tissue to preserve quality of life. The expected result is the total destruction of aggressive tumor areas by focal or multifocal treatment strategy using the Focal One® device (EDAP-TMS, Vaulx-en-Velin, France). The tumor destruction is validated by the negative biopsy rate between 6 and 12 months post-treatment.
This phase 2, open-label, dual-center, two-arm randomized controlled trial (RCT) investigates the effects of 16 weeks of structured aerobic training, relative to usual care (print material with physical activity guidance). Prostate genomic signatures represent the functional activity of all genes in the genome and are converted into genomic risk scores which correspond to the probability of a progression event (chance of having more aggressive disease). A structured exercise program may alter the genomic risk score and improve prediction of aggressive disease.
The purpose of this study is to test the ability of a new PET scan radiotracer, called FDHT (stands for [18F] Dihydro-Testosterone), to better find and monitor prostate cancer. Radiotracers are a type of drug that carries small amounts of radioactivity that can be seen by the PET scanner. FDHT is a radiotracer that looks for a protein which is present in almost all prostate cancer cells. The investigators want to find out if we can find and monitor changes in cancer using a FDHT PET scan.
This study investigates the pathologic effects of the combination of enzalutamide, abiraterone acetate, dutasteride, and degarelix when given for 12 weeks prior to prostatectomy in men with localized prostate cancer. Enzalutamide, an androgen receptor (AR) antagonist, blocks binding of testosterone to the AR as well as preventing nuclear translocation of the AR and DNA binding. Abiraterone acetate inhibits the CYP17 pathway, which is involved in the formation of androgens. Dutasteride is a 5-alpha-reductase inhibitor which blocks conversion of testosterone to dihydrotestosterone. Degarelix, a gonadotropin-releasing hormone (GnRH) antagonist, binds to GnRH receptors on the pituitary gland thus suppressing testosterone release from the testes. Therefore it is hypothesized that the combination of enzalutamide, abiraterone acetate, dutasteride, and degarelix will result in near-complete AR inhibition and produce favorable pathologic changes after 12 weeks of therapy.
The purpose of this study is to evaluate the safety and effectiveness of AD5-SGE-REIC/Dkk-3 in patients with localized prostate cancer.
This is a pilot prospective biomedical study of interventional type which includes 17 patients on 24 months (12 months of inclusion and 12 months of follow-up). The objective of this study is to verify that the focal therapy technique used (with the help of Koelis® system) allows to obtain optimal dosimetric coverage of the prostate target (ie dose of 160 Gy +-5% delivered on the envelope isodose) evaluated by CT scan performed 30 days after implantation.
Incontinence is one of the most common complications of radical prostatectomy. The continence rate is not significantly improved even by robot-assisted laparoscopic prostatectomy (RALP). However, some reports suggested that posterior reconstruction (PR) behind vesicourethral anastomosis could improve early recovery of continence during open, laparoscopic or robot-assisted radical prostatectomy. But, recent prospective studies reported no benefit of PR after RALP, which was the opposite result of those of previous studies. However the PR techniques used in these prospective studies seem to be quite different from the previous techniques. They seem to have used single-step PR, which opposes the median dorsal fibrous raphe (MDFR) only to the Denonvilliers' fascia (DF). By contrast, the original technique incorporated additional reconstruction between the MDFR and the posterior bladder wall 1-2 cm from the new bladder neck. Our group identified this anatomic structure as the posterior counterpart of the detrusor apron (PDA). The PDA is a strong, thick functional tissue containing muscle that is more appropriate for pulling and fixing the MDFR than the DF. As such, we hypothesized that the key proximal structure for PR is not DF, but rather PDA. Furthermore, single-step reconstruction between MDFR and PDA could be enough for PR. We previously investigated whether our new PR technique, which entails opposition of the MDFR solely to the PDA, would improve continence recovery compared with the standard RALP technique without PR. And our retrospective study demonstrated that this new PR technique during RALP significantly shortens the time to the recovery of continence compared with the standard technique, which does not incorporate PR (Int J Urol, 2012;19:683-7). Thus, we plan to validate this result by a well-designed, prospective, randomized controlled study.
