Filter by:The investigators have used national VHA data to demonstrate real-world efficacy of abiraterone and enzalutamide in Veterans with mCRPC. In the real-world that is the VHA, the investigators have successfully estimated g values that accurately predict OS and the use of this metric in other settings should now be explored. In the egalitarian system that is the VHA the treatment of prostate cancer is excellent, uniform across the US and indifferent to race. The choices made are clearly personalized, given not all men received all therapies and that younger Veterans were treated more aggressively. But with survivals that rival those in registration trials that enroll optimally fit individuals usually not encumbered by the co-morbidities that afflict many Veterans, the outcomes are testimony to the fact that for this common malady of older Veterans with whom VA physicians have broad experience the care administered is unsurpassed. Importantly this care at least as regards Veterans with mCRPC demonstrates that given equal access to health care, African Americans with prostate cancer fared as well if not better than Caucasians and importantly had better outcomes with abiraterone, an observation needing further exploration as these therapies move up front.
The purpose of this study is to look at the effects of a 10-week stress management in-person group program. The program will study emotions, stress, and stress management techniques (such as relaxation and coping techniques) on quality of life, distress, depression, and physical health in Spanish- speaking, Hispanic/Latino men diagnosed with Prostate Cancer (PC).
For the treatment for intermediate- and high-risk prostate cancer, Cyberknife boost will be used after 4 weeks of intensity modulated radiotherapy to pelvis. The boost doses are 18 Gy and 21 Gy in 3 fractions, respectively. The investigators plan to evaluate the toxicity of two dose groups and decide the appropriate dose for Cyberknife boost. Also, PSA control will be evaluated.
Background: Currently, patients suspected of having prostate cancer undergo ultrasound-guided systematic biopsies of the prostate. However, up to a quarter of clinically significant tumors, which may pose a risk to patient's well-being, may be missed on random biopsies. MRI enables detection of further tumors in this patient population, but also has limited accuracy. Study hypothesis: We hypothesize that hybrid PET-MRI, a novel scanner which incorporates MRI with molecular imaging will improve the detection rate of clinically significant tumors. Study design: In this prospective trial, we will recruit 57 men who are suspected of having prostate cancer but have had negative systematic biopsies, who have been diagnosed with low-risk disease but have clinically signs of more aggressive tumor or who have a focal tumor detected and are candidates for minimally-invasive tumor ablation (=tumor destruction with laser or ultrasound waves), in whom it is crucial to exclude other tumor sites. All patients will undergo PET/MRI after injection of a radiopharmaceutical called "18F-DCFPyL". This is a radioactive probe which has been shown in preliminary studies to be sensitive and specific for detection of prostate cancer. All lesions detected on PET/MRI will undergo biopsy under ultrasound using fused PET/MRI and ultrasound images for guidance, and compared to histopathology. The primary outcome measure in this study is the proportion of clinically significant prostate cancers that are detected with PET/MRI compared to MRI alone. Improved detection of clinically significant prostate cancer may enable a tailored, personalized therapeutic approach, decreasing morbidity and potentially improving overall patient outcome.
Objectives I. Compare, in a randomized Phase III multi-institutional setting, symptom-free survival time of patients with asymptomatic carcinoma of the prostate (T0-4, N0-2, M0) not suited for local curative treatment who are randomly assigned to immediate vs. delayed endocrine intervention (orchiectomy or luteinizing hormone releasing hormone (LHRH) agonist therapy). II. Compare the overall survival of these two groups of patients. III. Compare the time to first evidence of distant progression (N4 or M1) of these two treatment groups. IV. Evaluate the prognostic significance of pretreatment laboratory data and monitor these parameters following endocrine therapy. V. Study the prognosis of various sub-groups of patients stratified according to performance status, local tumor extent, nodal status, and choice of endocrine treatment.
Background: - Advanced prostate cancer is treated with surgery or drugs that lower the levels of androgens (male hormones) in the body. However, some cancers become resistant to this treatment. These types of cancers are known as castration-resistant prostate cancers. - Interfering with the growth of blood vessels that feed tumors can slow prostate cancer growth. Trebananib (AMG 386), a new anticancer drug, targets the blood vessels that feed tumors. It has been tested for different types of cancer, but not for prostate cancer. Researchers want to see if AMG 386 can slow disease progression in men with castration-resistant prostate cancer. AMG 386 will be given with abiraterone and prednisone, two drugs that are also used to treat advanced prostate cancer. Objectives: - To test the safety and effectiveness of AMG 386 with abiraterone for castration-resistant prostate cancer. Eligibility: - Men at least 18 years of age with castration-resistant prostate cancer. Design: - Participants will be screened with a physical exam, medical history, and imaging studies. Blood and urine samples will also be collected. - Participants will be separated into two groups. - The first group will have AMG 386 once per week for a total of four doses during a 28-day cycle. They will also take abiraterone once a day and prednisone twice a day, every day of the cycle. - The second group will not have AMG 386. They will take abiraterone once a day and prednisone twice a day, every day of the 28-day cycle. - Treatment will be monitored with frequent blood tests and imaging studies. - Participants will continue to take the study drugs as long as the disease does not progress and there are no severe side effects.
