Active clinical trials for "Prostatic Neoplasms"

Assessing the feasibility of implementing real-time multi-leaf collimator (MLC) tracking to account for the relative motion of the moving prostate tumour target and the static pelvic nodal target for high-risk prostate cancer patients. The capability of tracking for the relative motion of multiple targets will ensure that all the treatment targets receive correct dose as prescribed by the doctor and minimise side effects to the critical organs.

The purpose of this study is to compare the diagnostic performance of [89Zr]-Df-IAB2M PET/CT with that of [111In]-capromab pendetide as an immuno PET tracer in the detection of prostate cancer pre-prostatectomy as confirmed by pathology. Individuals participating in this study will have a [111In]-capromab pendetide scan, as well as a PET scan following the injection of [89Zr]-Df-IAB2M.

The purpose of this research study is to see if recurrent prostate cancer can be identified using a special procedure called a positron emission tomography (PET) scan. PET/CT is used to describe information regarding the function, as well as location and size of a tumor.

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.

This clinical study will evaluate the role of combination therapy of Provenge followed by docetaxel for patients with metastatic castration-resistant prostate cancer (CRPC, (prostate cancer that is resistant to medical or surgical treatments that lower testosterone). The purpose of this study is to look at the combination therapy of Provenge followed by docetaxel to correlate the immunological biomarkers with clinical results for therapy. Biomarkers are genes, proteins and other molecules that affect how cancer cells grow, multiply, die and respond to other compounds in the body. The study drugs are approved by the Food and Drug Administration (FDA). Treatment will be administered on an outpatient basis. Patients will receive Provenge followed by 6 cycles of docetaxel. Provenge is an immunotherapy (vaccine made from patient's own blood cells) that reprograms immune cells to attack cancer. A course of therapy consists of three doses of Provenge administered at 2-week intervals. Docetaxel is an antineoplastic (chemotherapy that affects cancer cell growth) agent. Docetaxel dose of 75 mg/m2 will be given intravenously as a 1-hour infusion every 21 days on Day 1 for 6 cycles (21 days). The strategy aims to determine whether cytokine production and T cell infiltration of tumor cells could favor regression using a combination of vaccine plus chemotherapy. Tissue endpoints will include biopsies prior to vaccine therapy and chemotherapy and at the end of therapy. Prostate cancer tissue infiltrates will be studied for expression of CD3, CD4, CD8, CD25/FOX3P, CD56, CTLA-4, PD-1, and Ki67. Additional immunological endpoints will be secondary antigen spread and various cytokine biomarkers.

The primary purpose of this study is to investigate the effect of intravenous magnesium on blood pressure after Trendelenburg position during robot assisted prostatectomy. The secondary purpose of this study is to investigate the effect of intravenous magnesium on pain after robot assisted prostatectomy.

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.

Cabazitaxel is already approved by the Food and Drug Administration (FDA) for use in patients with advanced prostrate cancer, following docetaxel therapy. The purpose of this study is to better understand the response and toxicity of cabazitaxel of elderly men (age 75 years and older) with advanced prostate cancer who have progressed during or after treatment with docetaxel. All patients on this study will receive cabazitaxel by intravenous (through a vein) infusion plus prednisone by mouth twice daily, and following the chemotherapy infusions, an injection of a granulocyte colony-stimulating factor (G-CSF). G-CSF will help the body produce more white blood cells, which should help decrease the risk of getting an infection while being treated with cabazitaxel.

The main object of this multicenter, randomized, double-blind, placebo-controlled phase III trial is to assess impact of maintenance of orteronel on disease progression and hence on quality of life of patients with metastatic castration resistant prostate cancer pretreated with novel hormonal agents who have non-progressive disease after chemotherapy with a taxane.

Background: - Ferumoxytol is an approved iron replacement therapy agent that has some potential for use as a contrast agent in imaging studies of the lymph system, especially involving lymph nodes that have been affected by cancer. Ferumoxytol is taken up by normal lymph nodes, but excluded from cancerous lymph node tissue. Because Ferumoxytol has not yet been approved for use as an imaging agent, researchers are interested in testing its effectiveness as a contrast agent for studies of normal lymph tissue and cancer tissue in lymph nodes of individuals with prostate cancer. Objectives: - To evaluate the safety and effectiveness of Ferumoxytol as a contrast agent in individuals who are scheduled to have prostate removal surgery to treat prostate cancer. Eligibility: - Men at least 18 years of age who have been diagnosed with prostate cancer and are scheduled to have surgery to remove the prostate and surrounding lymph nodes. Design: Participants will be screened with a full medical history and physical examination, blood and urine tests, and tumor imaging studies. Participants will have a magnetic resonance imaging (MRI) scan to provide baseline images for the study. Participants will receive an injection of Ferumoxytol and will return for another MRI scan on the following day (around 24 hours later). Some participants may have a third MRI scan 48 hours after the initial injection of Ferumoxytol. This third MRI scan is optional and not required by the study. Although the scanning and followup portion of the study will last only a few days, participants will be considered to be enrolled on the study until after the prostate removal surgery.
