Filter by:This pilot study will explore the prevalence of expression of four immune checkpoint biomarkers on circulating tumor cells (CTCs) from men with metastatic prostate cancer that are captured by EpCAM via the CellSearch method, and specifically defined as co expressing DAPI and cytokeratin, and lacking CD45 expression.
Obesity, known to be associated with a pro-inflammatory, pro-thrombotic humoral milieu, confers a worse prognosis in prostate cancer (PrCa). Circulating tumour cells (CTCs) are identified in the blood in advanced cancer. Their quantitation provides prognostic information. "Cloaking" of CTCs by adherent platelets impedes natural killer (NK)-cell clearance of CTCs from the circulation, enhancing metastatic spread. NK-cell function in blood and in solid organs is quantitatively and qualitatively reduced in obesity. Platelet cloaking may be enhanced in obesity due to the pro-inflammatory, pro-thrombotic state, and may be a mechanism for worse cancer-specific outcomes in this group. Obesity and its biochemical effects may be influenced by lifestyle changes such as exercise. Physical activity reduces levels of systemic inflammatory mediators and so an aerobic exercise intervention may represent an accessible and cost-effective means of ameliorating the pro-inflammatory effects of obesity. The ExPeCT trial will determine if a prescribed exercise intervention can ameliorate the degree of platelet cloaking in obese and non-obese men with advanced prostate cancer.
The aim of this study is to verify if the addition of enzalutamide to docetaxel is able to improve the disease control in first line CRPC patients.
A UCSF PI-initiated study with a primary goal to improve decision quality, anxiety, and uncertainty, thereby increasing appropriate uptake of active surveillance and reducing over-treatment of low-risk prostate cancer. This study involves: completion of questionnaires through the secure website; consultation by a health coach to aid men with prostate cancer in making informed treatment decision (personalized coaching session(s)).
This observational prospective single arm cohort study is designed to assess overall survival, symptomatic skeletal event free survival and quality of life of metastatic Castration Resistant Prostate Cancer (mCRPC) patients receiving Radium- 223 under real life conditions. In addition, time to next tumor treatment (TTNT), mobility, quality of life and selfcare, independence in activities of daily living and safety will be assessed.
Circulating tumor cells (CTCs) have the potential to provide a surrogate for'real-time biopsy' of tumor biological activity. Enumeration and molecular characterization of CTCs in prostatic cancer could play an important role in diagnosis, predicting the risk for tumor recurrence, and providing novel target therapy biomarkers. In view of these facts, the investigators wanted to demonstrate the value of multiparameter flow cytometry in detecting human tumor cells of prostatic cancer in normal peripheral blood after cryosurgery with or without dendritic cell(DC)-cytokine-induced killers(CIK) treatment, and the investigators also compared the specificity with reverse transcriptase polymerase chain reaction (RT-PCR) method.
The goal of this clinical study is to determine the efficacy and safety of Seviteronel, a lyase-selective inhibitor of CYP17 and an androgen receptor antagonist, in patients with castration-resistant prostate cancer (CRPC) who have been previously treated with enzalutamide and/or abiraterone.
This retrospective observational multi centered study has been established to collect the clinical experience relating to the administration of Fluciclovine 18F employed in both investigator initiated studies and named patient/compassionate use programmes in up to 5 sites.
Primary Objective: To assess the tolerability of cabazitaxel 25 mg per body surface area (m^2) with primary prophylactic polyethylene glycol-granulocyte-colony stimulating factor (PEG-G-CSF) in terms of the incidence rate of febrile neutropenia (FN) (defined: absolute neutrophil count [ANC] <1000 per volume [mm^3] and a single temperature of >38.3 degree or a sustained temperature of ≥38 degree Celsius for more than one hour) during Cycle 1. Secondary Objective: To assess overall rate of FN and grade ≥3 neutropenia and diarrhea; frequencies of dose delay due to adverse events (AEs); dose reduction due to AEs; relative dose intensity; incidences of FN-related hospitalization and use of intravenous (IV) anti-infectives; tolerability according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) v4.0; prostate specific antigen (PSA) response (50% decrease); tumor response according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 if available.
The purpose of this study is to better understand how cancer treatment may affect cancer cells. The research will involve genetic, molecular, cellular, and immunologic experiments using blood and tumor specimens. It is hoped that the information gained from these studies will lead to a greater understanding of castrate-resistant prostate cancer and potentially, improvements in cancer treatment. This is a tissue collection protocol requiring image-guided biopsies of metastatic, castration-resistant prostate cancer (mCRPC). The investigators will focus on enrolling patients with metastatic CRPC who have progressed while receiving novel AR-targeted therapeutics such as abiraterone and enzalutamide. This population of patients was selected because resistance develops relatively rapidly following potent inhibitors of AR activity and the mechanisms of resistance have to be better understood. Without comprehensive analysis of mCRPC tumor, the investigators will never gain a full understanding of the biology driving resistance in human disease and developing rational co-targeting approaches will not be possible.
