Molecular nuclear imaging in prostate cancer has made significant progress in the last few years. The introduction of tracers that target the prostate-specific membrane antigen (PSMA) has profoundly influenced imaging diagnostics in prostate cancer. In case of relapse after curative treatment (especially after radical prostatectomy), PSMA positron emission tomography (PET) has the ability to detect lesions already at very low prostate-specific antigen (PSA) levels. The improved detection of relapses increases the interest of individualized targeted therapies in patients with prostate cancer recurrence. Thus, this development led to the acceptance of PSMA PET for diagnostics in prostate cancer patients with biochemical relapses in national and international guidelines.
Previous studies have reported that cancer survivors develop age-related chronic conditions like frailty, sarcopenia, cardiac dysfunction, and cognitive impairment earlier and/or at a greater burden than similarly aged individuals never diagnosed with cancer or exposed to cancer therapies. However, the knowledge about aging-associated consequences of cancer treatment and the processes that underlie differential responses to therapy is very limited. In 2018, a think tank established by the National Cancer Institute has defined various research needs to expand the evidence base for aging-related consequences of cancer treatment, such as studies to examine aging-related processes that include regularly performed assessments capturing factors associated with physical function or studies to elucidate pathways that lead to the emergence of aging phenotypes and to understand the relationships between biomarkers of aging and functional outcomes in cancer survivors. In addition, study inclusion of older adults with comorbidities and higher levels of frailty has been proposed to achieve an improved understanding of functional outcomes at any age. Hypotheses / objectives We hypothesize that prostate cancer radiotherapy accelerates aging-related processes, furthermore, aging-related biomarkers may predict functional outcomes and represent early indicators of aging phenotypes. Primary objectives of the proposed study are the determination of the aging-related consequences of radiotherapy in prostate cancer patients and the evaluation of the relationship between biomarkers of aging and age-related clinical conditions.
to compare the efficacy of HIFU treatment with standard treatment in two situations: 1. as first-line cancer treatment, HIFU is compared to radical prostatectomy. 2. for patients with recurrence after external beam radiotherapy, HIFU treatment is compared to radical prostatectomy.
Caregivers of men with prostate cancer report high physical and emotional distress, and there is an urgent need to develop cost-effective programmes to prepare them for their roles. An online tool has been developed recently, aiming to offer a convenient, efficient, and potentially effective solution. However, pilot testing is required to evaluate this dyadic, Tailored, wEb-based, psychosocial and physical activity self-Management PrOgramme (called TEMPO) for caregivers of prostate cancer survivors. This study will assess TEMPO's acceptability, feasibility, cost, and potential efficacy, in addition to documenting the benefits (costs and outcomes) gained from involving both the caregiver and the patient in the intervention. A total of 80 patient-caregiver dyads will be recruited and randomized to a) TEMPO, or b) usual care. Acceptability, feasibility, and cost indicators will also be collected. Quality of life, anxiety, self-management skills, physical activity, self-efficacy, appraisal, and depression will also be assessed at baseline and 3 months post-baseline. In addition, intervention dyads will be invited to participate in an exit interview. This pilot study aims to assess the feasibility of the project, to inform the development and planning of a larger trial.
The interpretation of prostate multiparametric MRI (mpMRI) is difficult and requires expertise. As a result, it suffers from substantial inter-reader variability. The so-called Prostate Imaging Reporting and Data System (PI-RADS) scoring system has been launched in 2012 to try and standardise prostate mpMRI interpretation. It is a 5-level score that assesses the likelihood that suspicious focal prostatic lesions seen on mpMRI are clinically significant prostate cancers. Despite the use of semi-objective criteria for each category of the score, the inter-reader reproducibility of the first two versions (PI-RADS v1 launched in 2012 and PI-RADS v2 launched in 2015) was moderate at best, even for experienced readers. The last version (PI-RADS v2.1) has been launched in March 2019 in an effort to improve the inter-reader reproducibility. This version has not been evaluated yet. The purpose of our study is to evaluate the accuracy and inter-reader reproducibility of the PI-RADS v2.1 score on a large set of 171 prostate MRIs using 21 readers of varying experience. Twenty-one readers (14 seniors and 7 juniors) from 9 different institutions and with varying experience in prostate mpMRI accepted to participate to the study. Reader will assess the dataset independently and will be blinded to the other readers' results. They also be blinded to clinical and biochemical data.
Approximately one third of prostate cancer patients experience biochemical relapse following initial radical prostatectomy or curative radiotherapy. To determine further treatment, it is of utmost importance to accurately differentiate local and regional recurrence from distant metastatic disease. Unfortunately, the currently used medical imaging methods (MRI and bone scan) lack sensitivity for detection of nodal and skeletal metastases, which can lead to over-treatment of patients with occult metastatic disease. PET imaging with prostate specific membrane antigen (PSMA)-ligands has shown a promising potential for improving the detection accuracy in recurrent prostate cancer, especially when combined with the excellent soft-tissue contrast of MRI. However, evidence is mostly based on retrospective single center studies so far, including patients with a wide variety of PSA levels. Improving the sensitivity for detection of metastatic disease is a crucial step in reducing over-treatment of prostate cancer patients with biochemical relapse following radical treatment. The purpose of this prospective multi-center study is to standardize PSMA PET/CT and PET/MRI imaging across three university hospitals in Norway, and investigate its merit for detection of recurrent prostate cancer. The long-term overall goal is offering prostate cancer patients a more personalized treatment plan aiming to improve the chances of survival and quality of life.
This is a single-arm pilot study to evaluate the use of web-based video conferencing as a method of exercise training delivery. This study will include 10 female breast cancer survivors and 10 male prostate cancer survivors. For the first 12 weeks on study (Part 1), participants will train with an exercise physiologist (EP) for 150 minutes/week. This training will be delivered by web-based video conferencing. For the next 12 weeks (Part 2), participants will be instructed to do patient-directed exercise.
This phase I trial studies the impact of monosodium glutamate (MSG) on 68GA-PSMA-11 PET/CT in decreasing the salivary glands uptake in patients with prostate cancer. Prostate specific membrane antigen (PSMA) is a molecule that is overexpressed by the prostate cancer cells. 68GA-PSMA-11 is an imaging radioactive drug that can target this molecule in tissues for imaging and therapy of prostate cancer. Food substances, such as monosodium glutamate, may reduce salivary gland uptake of 68GA-PSMA-11. Ultimately, giving MSG may reduce potential harm and injury to the salivary glands in patients with prostate cancer treated with PSMA-targeted molecular radiotherapy.
Study to gather information about the optimal placement of Ra-223 in the order of different treatments in terms of the effect on patients and in terms of the use of healthcare services for the treatment of Canadian patients with prostate gland cancer which spread to other parts of the body. In order to collect this information real world data from prostate gland cancer patients from four Canadian administrative databases will be analyzed. Data collected from patients treated with their 2nd line of life-prolonging therapy for Non-Metastatic Castration Resistant Prostate Cancer (mCRPC) initiated from 01 Jan 2012 to 31 Dec 2017. For patients included in the study, all available data from the beginning for their record until death, lost to follow-up or database cut-off will be included. The index date is the date of initiation of the 2nd line life-prolonging therapy for mCRPC.
