Filter by:The investigators are attempting to determine if a new form of imaging called 18F-DCFPyL PET/CT is helpful to physicians in deciding how to manage suspected prostate cancer recurrence. This imaging uses a Positron Emission Tomography/Computed Tomography (PET/CT) scan using a radioactive tracer 18F-DCFPyL that is concentrated in prostate cancer cells and can potentially identify cancer cells throughout the body. The combination of 18F-DCFPyL PET/CT can potentially identify areas of prostate cancer recurrence not seen with usual imaging [bone scan, computed tomography (CT) thorax, abdomen and pelvis, plus multi-parametric magnetic resonance imaging (MRI)].
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.
Objective: To focus the high dose radiation to the gross tumor in the prostate while maintaining adequate dose for control of microscopic disease elsewhere in the prostate. In order to test the incorporation of the robust MRI and TRUS fusion algorithm in the clinical setting the investigators planned a study of Focused therapy with a primary endpoint of accurate localization of the high risk region. This is a pilot study of dose painted permanent I-125 seed implant to verify absence of tumor cells outside a high risk region using multi-parametric MRI and deformable TRUS registration. The high risk region will be dose painted to 160 Gy and the rest of the prostate will receive the normal prescription dose.
This is a randomized study to evaluate the efficacy and safety neoadjuvant androgen deprivation therapy with goserelin and abiraterone with or without apalutamide prior to radical prostatectomy for patients diagnosed with localized high-risk prostate cancer.
Prostate cancer is a leading cause of cancer death among men in the Western world. Early detection of prostate cancer has been shown to decrease mortality, but has limitations with low specificity leading to unnecessary biopsies and over-diagnosis of low-risk cancers. The STHLM3 trial has paved the way for improved specificity in early detection of prostate cancer using the blood-based STHLM3 test for identifying men at increased risk of harbouring significant prostate cancer. Targeted prostate biopsies based on MRI images have been shown to increase sensitivity of high-grade cancers compared to the currently used systematic biopsies, but existing evidence are contradictory and not free from methodological flaws. The primary aim of STHLM3-MR/Fusion is to increase the specificity in early detection of prostate cancer without decreasing the sensitivity of aggressive prostate cancers by introducing targeted prostate biopsies and comparing to traditional prostate biopsies. The primary endpoints are the number of performed biopsies and the number of detected high-grade prostate cancers defined as Gleason 7 or higher. Secondary endpoints include the number of low risk prostate cancers diagnosed and the proportion of patients with up-or downgraded disease after assessment of prostatectomy specimen. Additional aims include to assess the health economic consequences of implementing MRI based prostate cancer diagnostics and to improve the quality and effectiveness of prostate cancer diagnosis in the routine health care in Stockholm. The STHLM3-MR/Fusion project will be performed in two separate phases, analyzed separately. Based on power calculations, approximately 500 planned for prostate biopsies will be included in the first phase. Men who have previously been diagnosed with prostate cancer may not take part in the study. The study period of Phase 1 is March 2016 to January 2017. The second phase will start in autumn 2016 and end by December 2017.
The purpose of this study is to find out the effects of giving durvalumab alone or in combination with tremelimumab on this type of cancer. In addition, this study will look at the side effects of durvalumab when given alone or in combination with tremelimumab.
An exploratory, feasibility and proof-of-concept study to evaluate the capability of a rectal probe scintigraphy device (ProxiScanTM) to detect PSMA specific radiopharmaceutical agent (ProstaScint®; as a surrogate marker for prostate cancer) in patients who have undergone a radical prostatectomy for their disease, patients with multiple negative prostate biopsies and patients with known primary prostate cancer. Developed by Hybridyne Imaging Technologies, Inc. ProxiScanTM is a small cadmium zinc telluride (CST)-based compact gamma camera. It is the same size as a trans-rectal ultrasound (TRUS), currently used for prostate biopsy guidance. Men with multiple positive biopsies will be considered controls. Prostate cancer sextant biopsy histology results will be correlated with ProxiScanTM, TRUS, MRI and SPECT/CT. The investigators hypothesize that it will be safe and feasible to utilize a rectal probe scintigraphy (ProxiScanTM) to detect PSMA specific ProstaScint®, thus identifying and localizing the tumour sites within the prostate and surrounding areas.
This is a randomized parallel group trial designed to evaluate the impact of implementing geriatrician-prescribed interventions based on the comprehensive geriatric assessment (CGA), on the ability to deliver adequate chemotherapy treatment, as measured by relative dose intensity (RDI).
In this observational cost efficacy study, the investigator compare the Laparoscopic Radical Prostatectomy (LRP) versus Robotic-Assisted Laparoscopic Prostatectomy (RALP). Every cost of care that include hospitalization related or post operative medical consumption are obtained and recorded up to 5 years follow up. Functional results (continence, potency, quality of life) are obtained through standardised questionnaires. Carcinologic results are estimated by Prostate Specific Antigen (PSA) relapse and salvage treatments. Economic evaluation will be made to estimate direct costs of the four postoperative year along with the incremental cost-effectiveness ratio (ICER) per successful surgical treatment (preserved urinary continence and erectile function and PSA < 0.2).
To determine the impact of Decipher test results on adjuvant treatment decisions of high-risk post-RP patients with undetectable post-op prostate specific antigen (PSA) compared to clinical factors alone.
