Filter by:The number of metastases in a patient with primary or recurrent prostate cancer has major prognostic implication. The purpose is to compare, in a pilot study, the diagnostic performance of 18F-NaF-PET/MR with respect to the results of the scintigraphy 99mTc-MDP-SPECT/CT (routine exam) for determining the presence or absence of bone lesions in prostate cancer patient, with up to five metastases (oligo-bone metastatic) based on scintigraphy 99mTc-MDP-SPECT/CT. The gold standard will be a combination of clinical follow-up, additional imaging and biopsy, as indicated by the multidisciplinary discussion at the tumor board. The findings from whole-body 99mTc-MDP-SPECT/CT, 18F-NaF-PET/MR, and the combination of the 2 modalities will be categorized by 2 teams of 2 readers as benign or probably benign, equivocal, or malignant or probably malignant and compared with the results of follow-up for JAFROC and ROC analysis.
This is a phase II single center study using contrast-enhanced ultrasound to identify aggressive forms of prostate cancer with subharmonic imaging. The following are the study objectives: 1. To implement subharmonic imaging technology on a transrectal probe suitable for prostate imaging and biopsy 2. To demonstrate visualization of prostatic vascularity using subharmonic contrast-enhanced imaging. 3. To provide a preliminary estimate of the diagnostic accuracy of contrast-enhanced subharmonic imaging for detection of clinically significant PCa. The study will include 50 subjects who are scheduled for prostate biopsy. Each subject will receive an intravenous infusion of microbubble contrast material immediately prior to a prostate biopsy procedure. The study will demonstrate whether subharmonic imaging with a microbubble contrast agent allows for detection of clinically significant prostate cancer.
Gas exchange disturbance frequently occurs in steep Trendelenburg position during robot-assisted laparoscopic prostatectomy or cystectomy. Due to increased intrathoracic pressure and absorbed carbon dioxide (CO2) gas insufflated into abdominal cavity, hypercapnia as well as hypoxia may occur. Inverse ratio ventilation or prolonged inspiratory time during mechanical ventilation has been reported to be improve gas exchange in adult respiratory distress syndrome. The investigators attempt to test the hypothesis that prolonged inspiratory time may improve the gas exchange during robot-assisted laparoscopic urologic surgery.
This study is conducted to obtain information about prostate cancer patients with bone metastases before the end of 2013. The incidence of second primary malignancies and overall survival in patients with castration resistant prostate cancer are of particular interest. Information from this study will serve as a historical reference for the REASSURE study (Background incidence study)
This is an open-label, single-arm, multi-center extension study to evaluate safety in patients with mCRPC of YONSA 500 mg (4 x 125 mg qd) with methylprednisolone (4 mg bid). Patients will have successfully completed an 84-day treatment with abiraterone acetate in a previous trial. Results from the final visit of the previous study will be used to determine patient's eligibility for this study. Patients in this study will be eligible to receive open-label YONSA with methylprednisolone for up to 12 months. Pharmacodynamic parameters of serum testosterone and PSA levels will be monitored. Disease progression will be assessed by PCWG2 criteria.
The purpose of this study is to evaluate the incidence of grade ≥ 3 neutropenia and/or neutropenic complications (febrile neutropenia, neutropenic infection) with two schedules of cabazitaxel (bi-weekly versus tri-weekly) plus prednisone in elderly men (≥ 65 years) with mCRPC previously treated with a docetaxel-containing regimen.
Prostate cancer patients have a number of excellent treatment options to consider, and quality of life following treatment is often a consideration in treatment choice. One critical quality of life concern for patients diagnosed with prostate cancer is sexual function. Previous studies point to a vascular mechanism of impotence post-radiation therapy, as opposed to a nerve-based mechanism following surgery. In this study, the critical vascular structures (internal pudendal artery and corpus cavernosum) are defined by MRI-based imaging and included in treatment planning for radiation treatments, hopefully preserving critical artery function. This study will collect erectile function preservation rates at 5-years post-vessel-sparing radiotherapy with or without aids using the patient reported using the simplified three-question erectile function scale.
Through this study, the investigators seek to identify the benefits (improved survival) and harms (more procedures, more treatment, side effects, and quality-of-life impact) from different surveillance frequencies-every three vs. six vs. 12 months. Using the National Cancer Database and quality-of-life data from a large group of prostate cancer survivors, the investigators aim to compare survival, procedures/tests, treatments, and side effects in prostate cancer survivors who are followed with alternative surveillance frequencies and compare quality-of-life outcomes. The overall goal of the study is to provide high-quality data that will allow development of a personalized, risk-based tailored approach to post-treatment surveillance for prostate cancer.
Can platelet rich plasma applied to nerve bundles at time of surgery help the nerve bundles heal? Subjects undergoing a Radical Prostatectomy who meet study inclusion/exclusion criteria will be consented to receive an intraoperative application of platelet-rich plasma, made from their own blood at the time of surgery, for application onto their neurovascular bundles in an effort to improve the healing process. Subjects will be followed for an additional 18 months to determine the efficacy and safety of this procedure.
Background and purpose: The purpose of this study is to investigate the effect of exercise on intratumoral natural killer (NK)-cell variability in patients with localized prostate cancer undergoing radical prostatectomy. The primary hypothesis is that exercise induces epinephrine-mediated intratumoral natural killer (NK)-cell infiltration in patients with localized prostate cancer, and that the infiltration is greater in patients performing High Intensity Interval Training compared to usual care controls. Currently there is a lack of randomized controlled trials examining different types of exercise in patients with localized prostate cancer. Moreover there is a need for studies including biological measurements to allow a full assessment of the effect of exercise on diverse biomarkers and mechanistic pathways, which may influence cancer survival. Subjects: Patients with histologically verified prostate adenocarcinoma scheduled for radical prostatectomy at Urologic Department, Rigshospitalet, Copenhagen, Denmark. Methods: In this randomized controlled pilot study 30 patients with localized prostate cancer undergoing radical prostatectomy will be included and randomized 2:1 to either High Intensity Interval Training (HIIT) exercise intervention or observational control receiving usual care from inclusion and until planned surgery (radical prostatectomy). All patients will undergo assessments at inclusion (baseline) and at follow-up after the exercise intervention period (maximum 8 weeks) 3-5 days prior to surgery. Assessments include: anthropometrics; blood pressure; resting hearth rate; cardiorespiratory fitness by cardiopulmonary exercise test (VO2 peak.); body composition by DXA scan; quality of life by self-report questionnaires; fasting blood sample measuring cholesterol, triglycerides, insulin, c-peptide, HbA1c, glucose, hormones and inflammatory markers. Biological tissue from tumor (primary prostate biopsies) will be retrieved from the respective local pathological departments and from the perioperative prostate specimen and sent to protocol analyses.
