Men with indolent forms of prostate cancer are managed expectantly using active surveillance, with a goal of delaying treatment and its deleterious side effects. However, almost 50% of men experience progression with this approach and require treatment. Elevated body mass index (BMI) is associated with a dramatically increased risk of progression to higher grade prostate cancer. The goal of the proposed research is to gather preliminary data evaluating the effects of a promising dietary strategy to delay cancer progression in overweight and obese prostate cancer patients undergoing active surveillance. The investigators hypothesize that a ketogenic diet intervention may reduce BMI and favorably alter the prostate microenvironment.
Target enrollment is 1000 prospectively enrolled subjects with an initial negative biopsy scheduled for repeat biopsy. Subjects must have had their negative index prostate biopsy procedure within 30 months of being scheduled for their repeat biopsy. All enrolled subjects will have all core tissues from the initial negative biopsy blinded and tested with the assay. All subjects will have serum and plasma samples obtained prior to DRE, and a urine sample collected immediately following DRE but in advance of the repeat biopsy; samples will be blinded and sent to MDxHealth for evaluation.
This study will target patients who have received a histopathological diagnosis of prostate cancer and who are undergoing treatment in various forms, including active PSA surveillance, surgical treatment, radiotherapy, endocrine therapy, and chemotherapy. The study will survey information about the patient at time of diagnosis, clinical staging, details of initial treatment, status of disease progression, and prognosis at the end point of the study. The purpose of the study is to clarify distribution of staging, the actual status of treatment choices and treatment outcomes.
The objectives of this study are to confirm the safety and efficacy of FCH-PET/CT and to establish our ability to reproduce results from the literature using FCH-PET/CT as a diagnostic and decision making tool in the management in two predefined groups of prostate cancer patients, specifically, biochemical recurrence and high risk staging. The primary endpoints of the study are the incidence of adverse events (AE) in the study population up to 24 hours following the scan, and the sensitivity and specificity of FCH-PET/CT vs CT on a per-patient and per-lesion basis.
To study effects Quell has on opioid consumption and pain relief in patients with cancer.
Prostate cancer is the second leading cause of cancer death in North American men older than 50 years. Prostate specific membrane antigen (PSMA) is a unique membrane bound glycoprotein, which is overexpressed manifold on prostate cancer cells and is well-characterized as an imaging biomarker of prostate cancer. Positron emission tomography / computer tomography (PET/CT) is a nuclear medicine procedure based on the measurement of positron emission from radiolabeled tracer molecules. 68Ga-HBED-CC-PSMA (DKFZ-11) (abbreviated 68Ga-PSMA) is a tracer for prostate cancer PET imaging. The strength of functional imaging methods is in distinguishing tissues according to metabolism rather than structure. Studies have shown that PET/CT imaging with 68Ga-PSMA can detect prostate cancer lesions with excellent contrast and a high detection rate even when the level of prostate specific antigen is low. Study Objectives: The objective of this study is to evaluate if the patient-wide SUVmax on 68Ga-PSMA PET/CT in locoregional and metastatic prostate cancer correlates with histopathologic Gleason score at initial biopsy. It is hypothesized that SUVmax will correlate positively with Gleason score. This is of interest because non-invasive risk stratification may be possible in the future. This will be a single-site JGH-only open label study in which one (1) 68Ga-PSMA PET/CT will be performed on study participants. A PET/CT scan takes 2-3 hours.
Background: Prostate cancer is the most common non-skin cancer in U.S. men. Treatments for early or less aggressive disease are limited. Researchers want to test a device that destroys cancerous tissue with laser energy. They want to see if using it with ultrasound is more comfortable than using it with magnetic resonance imaging (MRI). Objectives: To test a cooled laser applicator system to treat prostate cancer lesions. To see if ultrasound imaging is a practical and feasible treatment with laser ablation for focal prostate cancer treatment. Eligibility: Men at least 18 years old with prostate cancer seen on MRI that has not spread in the body. Design: Participants will be screened with standard cancer care tests. These can include physical exam, lab tests, and MRI. For the MRI, they lie in a machine that takes pictures. Participants will have a prostate biopsy. Needle samples will be taken from 12 places in the prostate. This will be guided by MRI and ultrasound, which is obtained through a coil in the rectum. Participants will stay at the clinic for 1 2 days. A cooling catheter (plastic tube) will be put in the bladder. Ultrasound will guide the laser applicator directly to the tumor. The cooling catheter will be removed. A different catheter will be put in the urethra to keep the bladder emptied. The next day, participants will have a physical exam and a PSA blood test. Participants will have 6 follow-up visits over 3 years. At each visit, they will have a physical exam and lab tests. At some visits, they will also have an MRI or other scans and a prostate biopsy.
The study, investigates the current physical activity promotion practices among physicians and nurses, as well as social norms toward physical activity during treatment among cancer patients and among physicians and nurses who treat or counsel cancer patients. For this purpose, four large surveys with health care professionals (specialized practitioners, N=300; general practitioners, N=300; oncology nurses, N=300) and cancer patients (N=1200, 400 patients each with breast, prostate or colorectal cancer) with a cross-sectional research design are conducted. Additionally, a follow-up-study with a sub-sample of cancer patients (N=180) will be conducted.
The purpose of this study is to evaluate the effectiveness of Focal-Fusion Bx at detecting clinically significant prostate cancer in a standard clinical environment.
Excessive tiredness (fatigue) is a common problem in cancer patients and can affect quality of life negatively. There is limited knowledge about the physical mechanisms that cause fatigue, and there is no medical treatment. Physical activity can reduce the inconvenience, but the investigators need to learn more about the type and intensity of exercise that works the best as well as how to motivate patients to exercise. The overall aim, is to evaluate the efficacy and cost-effectiveness of individually tailored high (H) and low/medium (LM) intensity physical training, with or without behavioural medicine (BM) support strategies, during adjuvant oncological treatment on; Cancer Related Fatigue (CRF),Quality of Life (QoL), mood disturbance, adherence to the cancer treatment, adverse effects, disease outcome, return to a daily life after completed treatment and return to work. The investigators will also describe changes in inflammatory markers and cytokines related to physical training and gene expressions following training to investigate whether these serve as mediators for the effects of physical training on CRF and QoL. This will be evaluated in newly diagnosed breast, colorectal and prostate cancer patients during adjuvant therapy at three different centres in Sweden; Uppsala, Lund/Malmö and Linköping. A 2x2 factorial design will be used, 600 patients will be randomised to H, H+BM, LM or LM+BM. Patients will train two times per week during 6 months. This project will give; new knowledge about aspects for individuals to gain improved well-being and quality of life, facilitated return to work, and possibly reduced risk of cancer recurrence. This in turn would result in lower burden on the health care system, reduced societal costs and have a positive impact on public health. Implementation of the results into clinical practice will be facilitated by the close collaboration between researchers and clinicians, and the fact that the study is performed in clinical settings.
