A proportion of prostate cancer (PCa) patients develop relapse following curative local treatment. Regional nodal recurrence is an emerging clinical situation since the introduction of new molecular imaging methods in the restaging of recurrent prostate cancer. More specifically, a subgroup of these patients is being diagnosed with a recurrence confined to the regional lymph nodes and limited in number (oligorecurrence) using choline or PSMA PET-CT. As there are no specific treatment recommendations for these type of patients, different treatment approaches are currently used, mostly focusing on local ablative treatments using radiotherapy or surgery. These treatments are coined metastasisdirected therapy (MDT). MDT in combination with or without temporary ADT could delay the subsequent risk of progression, and even cure limited regional nodal recurrences. Consequently, lifelong palliative ADT, with its toxicity and excess in non-cancer mortality might be postponed. The proposed trial randomizes patients with oligorecurrent nodal prostate cancer following primary PCa treatment to either metastasis-directed therapy (MDT) (salvage lymph node dissection, sLND or stereotactic body radiotherapy, SBRT) or MDT plus whole pelvis radiotherapy (WPRT: 45 Gy in 25 fractions).
The aim of the focal treatment HIFU is to destroy the cancer without causing side effects in contrast to radical treatments. Radical treatments (surgery or radiation therapy) are the standard therapies for patient with intermediate risk localized prostate cancer and good life expectancy (prostatectomy if life expectancy10 years) By destroying only the part of the gland that harbors cancer, it may indeed be possible to provide efficient cure of the disease while minimizing treatment-induced morbidity (incontinence and loss of potency). Around 20% of patients presented with a unilateral tumor: this patients are currently treated radically. No study published papers reported outcomes of a large population (>100) with intermediate risk cancers treated with Focal-HIFU (conducted with the Focal One® device). Focal therapy must be only offer within clinical trial setting (EAU (European Association of Urology) Guidelines ). The aim of this cohort will be to determine the success rate of Focal-HIFU in this intermediate risk population. The result the study will be used for calculation the arms of a future random study
This multicenter study aimed at assessing the feasibility of Probe-based Confocal Laser Endomicroscopy (pCLE) during Robotic-Assisted Radical Prostatectomy or Laparoscopic Radical Prostatectomy for intra-operative characterisation of surgical margins.
This study is a large, prospective, pragmatic, controlled comparison of patient-centric outcomes [quality of life (QOL), toxicity, and disease control] between parallel cohorts of men with prostate cancer treated simultaneously at proton therapy facilities and at geographically similar conventional (photon-based) radiation facilities using intensity-modulated radiation therapy (IMRT) techniques.
Prostate cancer is the most frequently occurring male cancer in Belgium. Patients who have been treated for prostate cancer, i.e. by surgery and/or radiotherapy, in a substantial degree suffer from a tumor recurrence, often diagnosed by an increase in serum tumor marker PSA (prostate specific antigen) within the first few years. In these patients with evidence of a tumor recurrence after primary treatment, it is important to most exactly define the location(s) of tumor, to guide appropriate therapy by surgery, radiotherapy and/or hormonotherapy. In so-called oligo-metastatic disease targeted therapy may still be curative and prevent the disease from spreading to distant locations. Therefore it is of paramount importance to have an accurate tool of medical imaging to localize all possible locations to be treated. With some patients, the PSA-value is so low, that conventional nuclear medicine bone scanning or radiological CT or MRI cannot determine where the metastases are. Therefore, [18F]-Choline PET-CT was introduced to improve diagnostic imaging performance. However, in 30 to 40 percent of patients choline-PET does not localize tumor either, especially in small tumors and/or very low PSA values. The PSMA PET is already routinely used in many European centres, and has shown a superior accuracy in these patients as compared to conventional imaging techniques. This has been a very consistent finding in scientifically reported patient studies. Most of these investigations have been performed with PSMA labeled with Gallium-68. The investigators in Ghent, as others, have labeled PSMA with Fluor-18. This tracer provides many advantages, including a higher production yield enabling more patients to be scanned. Also from a perspective of radioprotection and financial costs, Fluor-18 is a better choice. Moreover, several recent studies, comparing Fluor with Gallium modalities seem to suggest equivalent or better diagnostic results, possibly because of a lower aspecific background activity.
This study will measure PSA values in men with IBD before, during, and following a flare. In addition, the effect of any PSA increase will be analyzed and correlated to the location of disease (rectal vs. other). Study findings may help men with IBD by identifying pitfalls in prostate cancer screening for this population and help to stratify and understand the effect IBD has on the prostatic milieu. By optimizing how men with IBD are screened for prostate cancer, future unnecessary healthcare encounters and expenditures may be reduced for this patient group.
This clinical trial will determine whether the addition of radiotherapy to standard of care first line systemic therapy improves objective progression-free survival rate (combined radiographic and clinical) at 18 months, compared to first line systemic therapy alone.
This is an Expanded Access Program (EAP) available to patients who have advanced cancers, who have failed or progressed on standard of care systemic therapy and do not qualify for ongoing clinical trials.
Single arm, multicenter, open-label Phase II study of the effects of parenteral testosterone in combination with nivolumab in men with metastatic castration-resistant prostate cancer who previously progressed on at least one novel androgen-receptor targeted therapy (i.e. Abiraterone acetate, Enzalutamide). Up to one taxane agent is permitted.
A randomized, prospective study to compare the direct and indirect costs, functional and oncologic results of 3D laparoscopic and robot assisted radical prostatectomy procedures.
