Filter by:The investigators propose is to perform a pragmatic, multicenter, open-label, randomised clinical trial to demonstrate the efficacy and safety of either continuing or further de-escalating BMA after a minimum of two years of BMA treatment in patients with bone metastases from breast cancer and castration-resistant prostate cancer
This is a master protocol for a prospective Phase I-II study evaluating feasibility and efficacy of incorporating magnetic resonance imaging (MRI) simulation into the planning of radiation treatments.
This study will use polysomnography, alongside other methodologies such as questionnaires, actigraphic measurements and salivary melatonin samples used in previous studies to investigate sleep quality in patients with i) localized, locally advanced or metastatic hormone sensitive prostate cancer or ii) with full-resected early (stage I-III) epithelial breast cancer. The measurements will be taken before androgen deprivation therapy (ADT - for prostate cancer patients) or endocrine therapy (for breast cancer patients) is initiated, at 6 months and some measures again at 12 months.The groups, defined by cancer type and whether or not treatment includes ADT / endocrine therapy, will be compared to see if there are differences in the prevalence of the lowered sleep quality in the groups.
This phase I/II escalation dose study is assessing the efficacy of the recommended dose of stereotactic re-irradiation (SBRT) of relapses within the prostatectomy bed, potentiated by metformin
The investigators hypothesize that an increase in dietary fiber intake during radiation therapy may provide better long-term intestinal health for the cancer survivor. If the hypothesis is not correct, the increased intake may only mean an increase in acute side effects. All participants are advised to consume at least 16 g of dietary fiber/day via food. In addition, participants are invited to take capsules that together contain either 5.5 g of dietary fiber from psyllium husk or placebo.
Prostate cancer is the first cancer in men. The treatment of metastatic prostate cancer with chemotherapy is based on the intravenous administration of docetaxel chemotherapy. Symptoms of anticipatory nausea, linked to anxiety caused by the treatment, may occur. Hypnosis is already used to treat the anxiety of people with cancer and can help treat the symtoms of nausea and vomiting of women with breast cancer. The purpose of the study is to evaluate the effect of medical hypnosis in virtual reality on the anxiety of patients with metastatic prostate cancer receiving Docetaxel chemotherapy treatment in comparison with a control group.
Apalutamide is an anti-androgen that blocks the effect of testosterone on prostate cancer growth. This phase IIa trial is designed to determine whether very low doses of apalutamide, given for 3 to 4 weeks before prostate surgery to men with prostate cancer confined to the prostate gland, reduces plasma levels of PSA (a biomarker of apalutamide's ability to block testosterone). If low dose apalutamide lowers PSA levels in this setting, further study of this agent in men with localized prostate cancer who wish to delay definitive therapy with surgery or radiation may be warranted.
Dose escalation is nowadays a standard strategy in radiotherapy for prostate cancer. Besides, it is believed that due to the radiobiology characteristics of prostate cells (low alpha/beta ratio), the delivery of higher radiation doses per fraction could theoretically improve the efficacy of the treatment. In this context, the combination of prostate brachytherapy and external beam radiotherapy (EBRT) has proven to be the most effective method of dose escalation significantly improving disease control in randomized clinical trials. Unfortunately, this strategy is also associated with an increased risk of acute and late adverse events compared to conventional EBRT alone. It has been proposed that this increase in adverse events could be related to the use Low-Dose-Rate (LDR) brachytherapy and that High-Dose-Rate (HDR) brachytherapy (a more modern and accurate procedure) could reduce this risk. On the other hand, Stereotactic Ablative Radiotherapy (SABR) is a high-precision radiation technique that allows the delivery of higher doses per fraction in fewer sessions, reducing the total treatment time. The investigators hypothesized that the combination of two highly conformal radiation techniques (HDR brachytherapy and SABR) could be well tolerated, while reducing total treatment time and therefore improving patient quality of life. This is a single arm Phase II clinical trial designed to test the feasibility, tolerability and impact on quality of life of the combination of High-Dose-Rate prostate brachytherapy and SABR for patients with intermediate and high-risk prostate cancer.
Prostate cancer (PCa) is the most common type of malignant tumor and the third leading cause of cancer-associated mortality among men worldwide. The biological behaviors of PCa at different degrees of malignancy also largely differ, directly impacting disease outcomes and responses to treatment. Therefore, accurate risk stratification of PCa before treatment and the development of an individualized treatment regimen, play a vital role to improve the clinical outcome of patients. However, overdiagnosis and unnecessary biopsies, which are invasive examinations associated with higher costs and adverse effects. When the PSA is less than 20ng/mL, less than 1% of PCa patients have a positive bone scan, and routine bone scans are not recommended for asymptomatic or low-risk PCa patients. Interestingly, due to the variations among evaluators that often occur when defining the T stage, biopsies operate inaccuracy, also low-PSA level can also occur metastasis, there is a need for an objective and accurate imaging biomarker for the diagnosis of different grade PCa. Prostate-specific membrane antigen (PSMA) is a type II transmembrane protein, which has higher expression in cancerous prostate cells than in normal prostate cells. Meanwhile, its expression level is positively correlated with the degree of malignancy, the tendency of metastasis, and the risk of early recurrence. In recent years, 18F-PSMA positron emission tomography/computerized tomography (PSMA PET/CT) has earned widespread attention as a novel imaging modality based on molecular-level analysis, rather than morphological or physiological analysis, to assist in PCa diagnosis and tumor burden evaluation. Currently, Maximum Standardized Uptake Value (SUVmax) is the most commonly used semi-quantitative parameter in PET/CT, which is used to assess tumor burden of PCa, and thus can be used as an imaging biomarker to assess the degree of malignancy of prostate cancers. However, prior studies mainly focused on the correlation between patients' biochemical recurrence lesions and the PSA levels and Gleason score. There is a lack of research to explore the correlation among primary PCa burden, PSA levels, and the degree of prostate cancer malignancy. The aim of this project is to use 18F-PSMA PET/CT SUVmax to analyze the correlation among primary PCa imaging, and clinical indicators, and to evaluate the predictive value for PCa risk stratification, metastasis risk, and biochemical recurrence.
This phase II trial studies how well white button mushroom supplement works in reducing prostate-specific antigen (PSA) levels in patients with prostate cancer that has come back (recurrent) or has favorable risk and has not undergone any therapy (therapy naive). PSA is a blood marker of prostate growth. White button mushroom supplement may affect PSA level, various parameters of immune system and levels of hormones that may have a role in prostate cancer growth.
