Filter by:This study evaluates the value of Gallium-68 labeled PSMA (68Ga-PSMA) for PET/CT imaging of prostate cancer recurrence. 68Ga-PSMA is a radioactive molecule, which binds to prostate cancer cells. Together with a PET/CT scanner, the distribution of 68Ga-PSMA can be determined in the body. To test this new drug, participants will receive an intravenous injection of Ga-68-PSMA and then have a PET/CT scan. The scan results will be made available to study participants and treating physicians.
This is a single-center, randomized, open-label study to assess the feasibility of a low-protein diet intervention in patients with metastatic castrate-resistant prostate cancer (CRPC) who are receiving treatment with sipuleucel-T. Subjects will be randomized (1:1 ratio) to either Arm 1 or Arm 2 (Fig. 1). Arm 1: Subjects randomized to Arm 1 will be treated with sipuleucel-T infusion on Day 1, every two weeks for a total of three infusions. Subjects on this arm will receive a control diet containing 20% protein. Arm 2: Subjects randomized to Arm 2 will be treated with sipuleucel-T infusion on Day 1, every two weeks for a total of three infusions. Subjects on this arm will receive a low-protein diet containing 10% protein. Patients with metastatic, asymptomatic or minimally symptomatic CRPC that has progressed despite androgen deprivation therapy will be eligible for the study. After informed consent eligible patients will be scheduled to receive sipuleucel-T (three infusions two weeks apart) with normal-protein diet vs. low-protein diet. Each cycle will be every 14 days. Diet intervention will commence 1 week prior to the first apheresis (Day -7) and will continue until 10 days after the last infusion of sipuleucel-T (Day +42) (Fig. 2).
Despite continuous technical improvements in urologic surgery, up to 40% of prostate cancer patients will develop biochemical recurrence after radical prostatectomy (RP), potentially because of micro metastasis at the time of the primary surgery. With improved radiological modalities and nuclear medicine tracers like 68Ga-PSMA PET/CT, which allow the localization of the site of recurrence, there is increasing interest in metastasis directed therapies, such as salvage lymph node dissection. The pelvic extended salvage lymph node dissection (sLND) is a promising option for treating prostate cancer patients with local recurrence after radical prostatectomy with curative intent. Several retrospective series has been published to determine the local value of sLND. Despite the first data seem to be feasible and promising, to date no prospective evaluation has been made. Thus sLND is still experimental according to the guidelines and is considered as an off label therapy. This prospective single center phase I/II study was conducted to investigate the safety and early efficacy of salvage lymph node dissection in prostate cancer patients with local pelvic recurrence after radical prostatectomy (RP) with curative intention.
Simultaneous PET/MRI has the potential to improve the detection accuracy in recurrent prostate cancer, since it combines the excellent soft-tissue contrast of MRI with the high molecular sensitivity of PET in a single imaging session. The aim of this study is to evaluate the sensitivity and specificity of simultaneous 18F-Fluciclovine PET/MRI for detection of recurrent prostate cancer.
Radiation therapy is considered a standard treatment option for the management of localized prostate cancer. Among the 20-30% of patients who recur, there is no consensus on the optimal salvage therapy. Salvage options available for isolated local recurrence include; temporary or permanent implantation of radioactive seeds into the prostate, complete removal of the prostate gland, use of low temperatures to treat the disease (cryotherapy), and high frequency ultrasound to treat the disease. There are risks of complications associated with all these treatments, and there is presently no consensus as to which treatment is the best. The aim of this pilot study is to look at the feasibility and toxicities of whole gland salvage treatment of the prostate using temporary implantation of radioactive seeds into the prostate.
This is a Phase II clinical study to determine if Metformin can increase Prostate Specific Antigen (PSA) doubling time for patients with Prostate Cancer who have failed primary treatment with radiation, or surgical patients that are at high risk for recurrence based on surgical pathology. Men with confirmed prostate cancer and rising serum PSA levels will receive Metformin and will be monitored for PSA response and disease progression.
To development of clinical assessment technique using multi-radiotracer positron emission tomography/magnetic resonance (PET/MR) in prostate cancer - to establish the optimal imaging technique of PET/MR using multiple radioactive tracers for prostate cancer - to establish the imaging biomarker using PET/MR for clinical assessment of prostate cancer and early detection of recurrent prostate cancer
Inclusion criteria: - Patients with biochemical recurrence (Phoenix criteria: PSA nadir + 2 ng/ml) after radiation therapy for prostate cancer addressed for prostate biopsy OR - Patients referred to our institution for biopsy-proven local recurrence after radiation therapy for prostate cancer but needing a re-assessment with biopsy (insufficient number of biopsy and/or imprecise location of positive biopsy and/or questionable diagnostic of recurrence) Study Design: - Included patients will undergo an endorectal US examination with a Histoscanning™ acquisition and a multiparametric (T2-weighted, diffusion-weighted and dynamic contrast-enhanced) MRI. - Two independent operators will separately define suspicious focal lesion on Histoscanning™ images and on MR images. - Random biopsies (at least 2 cores) will be performed in sextants negative at Histoscanning™ and at MRI ; In sextants positive at Histoscanning™ and/or at MRI, targeted biopsies will be performed in the suspicious part of the sextant (at least two cores per suspicious lesion). - Histoscanning™ and MRI results will be compared to biopsy results. A total of 30 patients will be included
Men with localized prostate cancer requiring intermittent androgen deprivation therapy for biochemical recurrence following radical therapy will be asked to participate in a phase 4 safety and efficacy clinical trial comparing 10 months versus 4 months of degarelix (Firmagon®) therapy with the endpoint of prolonging the off treatment interval.
