Filter by: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.
Prostate cancer (PC) remains the most-common non-cutaneous cancer diagnosed in American males, accounting for an estimated 174,560 estimated new cases and 31,620 estimated deaths in 2019. Up to 40% of the patients with prostate cancer develop biochemical recurrence within 10 years after initial treatment. Usually an increase of the prostate-specific antigen (PSA) llevel precedes a clinically detectable recurrence by months to years, and this is currently used as a screening test before and subsequent to treatment. However, disease advancement can be local, regional or systemic, and each has significantly different approaches to disease management. Unfortunately, PSA level does not differentiate between these disease stages. This phase 2-3 study explores the utility of radiolabel 68Ga-RM2, a 68-gallium (68Ga)-labeled gastrin-releasing peptide receptor (GRPr) antagonist, for positron emission tomography (PET) / magnetic resonance imaging (MRI) (collectively, PET/MRI) as a potential tool to help discriminate between disease stages in participants after treatment with surgery or radiation, who present persistently elevated PSA levels (ie, may have prostate cancer), but were negative for cancer with a diagnostic regular medical care computed tomography (CT) scan 68Ga-RM2 (BAY86-7548) is also identified as a synthetic bombesin receptor antagonist. PET/MRI is the collective result of 2 scan processes (PET and MRI ) conducted during the same scan procedure (ie, a combined scan). After a regular medical care computed tomography (CT) scan, participants will be scanned with 68Ga-RM2 PET/MRI scan procedure. PET/MRI is used to assess the location, size, and metabolic activity of a suspected tumor. The 68Ga-RM2 radiolabel consisted of a ligand (the synthetic bombesin receptor antagonist) and the radioisotope 68Ga. The RM2 ligand targets gastrin-releasing peptide receptors (GRPr), commonly expressed by prostate cancer cells, and the radioisotope distinguishes those cells from the background. The criteria for scan "positivity" will be, when compared to background level of the liver (control), the 68Ga signal is stronger (positive - malignant) or weaker (negative - benign). This study will assess how well 68Ga-RM2 works in detecting prostate cancer in patients with 68Ga-RM2 PET/MRI may be able to see smaller tumors than the standard of care contrast-enhanced CT or MRI scan.
This pilot phase I trial studies copper Cu 64 TP3805 (Cu-64-TP3805) positron emission tomography (PET)/computed tomography (CT) in detecting cancer in patients with prostate cancer undergoing surgery to remove the entire prostate and some of the tissue around it (radical prostatectomy). Many patients with benign lesions must undergo biopsy to test the lesion. Cu-64-TP3805 is a radioactive substance that attaches to cancer cells but not normal cells. PET/CT uses a scanner to make detailed, computerized pictures of areas inside the body where the radioactive substance is lighting up. Using Cu-64-TP3805 PET/CT scans and comparing them with cancer tissue obtained from surgery may help doctors learn whether Cu-64-TP3805 PET/CT can accurately detect prostate lesions and determine whether they are cancerous or benign, which may minimize the need for prostate biopsies.
This randomized pilot trial studies vaccine therapy and pembrolizumab in treating patients with prostate cancer that does not respond to treatment with hormones (hormone-resistant) and has spread to other places in the body (metastatic). Vaccines made from deoxyribonucleic acid (DNA), such as pTVG-HP plasmid DNA vaccine, may help the body build an effective immune response to kill tumor cells. Monoclonal antibodies, such as pembrolizumab, may find tumor cells and help kill them. Giving pTVG-HP plasmid DNA vaccine and pembrolizumab may kill more tumor cells.
Patients with locally confined prostate adenocarcinoma (clinical stage T1c - T2bN0M0, Gleason score 7, PSA 20 ng/ml) are assigned to one of two treatment arms. Low risk patients (T1c-T2a and PSA <10 ng/ml and Gleason Score 6 or less) will receive 5 fractions of 8.0 Gy for a total of 40 Gy. Intermediate risk patients (T2b or PSA >10 ng/ml orGleason Score 7) will receive 1.8 Gy of IMRT for 25 fractions over 5 weeks for a total of 45 Gy. They will then receive a boost consisting of 4, 5.5 Gy fractions after IMRT for a total of 22 Gy.
The goal of this clinical research study is to evaluate the safety of PEG-BCT- 100 given as an infusion to treat patients who bear advanced solid tumors that are dependent on arginine (melanoma, renal cell carcinoma, prostate cancer and hepatocellular carcinoma), and who have progressed after receiving approved or established therapies. This is a Phase 1 study; PEG-BCT-100 is an enzyme that degrades arginine and is an investigational drug.
This study is comparing the effectiveness of enzalutamide with or without abiraterone acetate for men with high-risk, localized prostate cancer.
This research trial studies molecular features and pathways in predicting drug resistance in patients with castration-resistant prostate cancer that has spread to other parts of the body and who are receiving enzalutamide. Studying samples of blood and tissue in the laboratory from patients receiving enzalutamide may help doctors learn more about molecular features and pathways that may cause prostate cancer to be resistant to the drug.
This phase I trial studies the side effects and the best dose of stereotactic body radiation therapy in treating patients with breast cancer, non-small cell lung cancer, or prostate cancer that has spread to other parts of the body. Stereotactic body radiation therapy delivers fewer, tightly-focused, high doses of radiation therapy to all known sites of cancer in the body while minimizing radiation exposure of surrounding normal tissue.
The present study is a phase III randomized and multicentric trial evaluating the potential additional impact effect of two years adjuvant androgen deprivation when combined with neoadjuvant (4 months) and high-dose (76 Gy) conformal radiotherapy in moderate high-risk prostate cancer patients. Stratification will be performed by prognostic factors and by participating institution.
