Active clinical trials for "Prostatic Neoplasms"

The cone beam image is a part of the radiotherapy treatment machine and uses lower energy xrays as the head of the radiotherapy machine moves around the patient in a circle. This takes pictures that give 3-dimensional information, somewhat like a CT scan. These images are better at showing the position of the tumour and surrounding soft tissues than the standard xrays that were previously used. Cone Beam Imaging Technology is not new and has been used regularly at The Christie for many years. The standard cone beam scan is taken before the actual radiotherapy treatment or after the treatment has been delivered. Volumetric Modulated Arc Therapy (VMAT or Arc Radiotherapy) is a novel method of delivering radiotherapy that involves the continuous movement of the radiotherapy treatment machine head around the patient and MLC during radiation. Arc radiotherapy has been clinically implemented at The Christie for prostate radiotherapy treatments and work is in progress for implementation in lung radiotherapy. The continuous gantry rotation inherent to VMAT delivery makes this simultaneous imaging possible, although there are concerns associated with the impact that this may have on patient dose and image quality. The aim of this research is to assess whether the image quality of cone beam scans taken during treatment are as good as standard cone beam scans taken before or after treatment used to determine the accuracy of patient position and the tumour coverage by radiotherapy.

This prospective study evaluates the clinical utility of a novel real-time localization system allowing for smaller volumes of normal tissue to be included in radiation field and determines dosimetric parameters and adverse effect profiles of radiation therapy using this technology. Subjects will have beacon transponders implanted into the prostate to more precisely localize the position of the organ during radiation therapy. Hypothesis: 1. Treatment with highly targeted radiation therapy can be delivered in a daily treatment time consistent with routine clinical practice. 2. Highly targeted radiation therapy with reduced PTV margin will result in a significant decrease in rectal and bladder volume treated.

The goal of this clinical research study is to create a registry (research database) of clinical data about patients who receive radiation therapy, with or without hormone therapy, to treat prostate cancer that has come back after surgical removal of the prostate. This treatment is standard and the actual treatment is not part of this protocol. The goal of this clinical research study is to create a registry (research database) of clinical data about patients who receive radiation therapy, with or without hormone therapy, to treat prostate cancer that has come back after surgical removal of the prostate. This treatment is standard and the actual treatment is not part of this protocol. Researchers want to collect data and use this registry to learn about the long-term status of prostate cancer after these treatments. This is an investigational study. Up to 500 patients will take part in this study. All will be enrolled at MD Anderson, Spartanburg Regional Healthcare System, and/or MD Anderson Cancer Center Albuquerque. Researchers want to collect data and use this registry to learn about the long-term status of prostate cancer after these treatments.

RATIONALE: Studying samples of blood and urine from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This clinical trial is studying blood and urine samples in patients with newly diagnosed localized prostate cancer treated with hormone therapy and radiation therapy.

This study enrolled men with prostate cancer who had failed hormone therapy (as shown by rising prostate-specific antigen [PSA] levels) and who were about to start a new line of chemotherapy. Blood was drawn prior to the patient receiving chemotherapy and then monthly thereafter for up to 18 months or until disease progression, whichever occurred first. The blood was tested to find circulating tumor cells (CTC) and to count them. The circulating tumor cell levels were studied in relation to the patient's overall survival. Serum was also collected for PSA testing, and additional blood samples were drawn to test for circulating endothelial cells and RNA was isolated for future gene expression testing.

Observational prospective study investigating the plasmatic levels of miRNA according to AR-V7 mutational status in mCRPC patients receiving standard of care therapy. At the time of the enrollment, patients will undergo determination of AR-V7 splice variants on circulating tumor cells and periodic assessment of circulating levels of miRNA at different time points during the treatment course (initiation, 8-weeks assessment, progression); irrespectively of AR-V7 status patients will be allocated to endocrine therapy with enzalutamide or abiraterone plus LHRH agonist (decapeptyl every 3 months) according to standard of care. Integration of local treatment (in particular radiotherapy) will be allowed on oligoprogressive sites of disease and its impact on overall outcome and miRNA levels will be assessed.

The aim of the study is to identify the specific patterns of communication between doctors and oncological patients during medical consultations and develop recommendations to improve its effectiveness.

This is a prospective observational study on a cohort of patients with castration-resistant prostate cancer M0, treated with Apalutamide, at the Oncology Unit of the "Andrea Tortora" Hospital of Pagani. Data will be collected on the patient's clinical history and the treatments carried out until the start of therapy with Apalutamide. At that time the study will be described to the patient and informed consent will be given. In case of a favorable opinion from the patient, the CRF will be filled in. Patients with CRPC M0 treated with Apalutamide, belonging to the Oncology Unit of the Pagani Hospital "Andrea Tortora" and of the other Oncology Units of the ASL of Salerno (Hospital of Vallo della Lucania) will be studied with the possibility of enrollment also from other Centers outside the Salerno ASL.

Prospective observational research study to evaluate the role of wearable activity monitors to predict physical function decline among prostate cancer survivors receiving ADT.

The purpose of this study was to explore the effectiveness of 68Ga-PSMA PET/MRI for improving the detection of csPCa in lesions with PI-RADS score 3. This study is a prospective, observational study, single-center research. After recruiting patients who are suspected prostate cancer with a mpMRI PI-RADS version2 score of 3 and willing to perform prostate biopsy to identify the diagnosis, 68Ga-PSMA PET/MRI will be performed. Lesions will be reaccessed based on PET/MRI findings and compared with the pathological results.
