Filter by:The Prostate Active Surveillance Study (PASS) is a research study for men who have chosen active surveillance as a management plan for their prostate cancer. Active surveillance is defined as close monitoring of prostate cancer with the offer of treatment if there are changes in test results. This study seeks to discover markers that will identify cancers that are more aggressive from those tumors that grow slowly.
Hamsa-1™ is an anti-angiogenic drug combination designed for the treatment of cancer. The investigational product Hamsa-1™ comprises of four well-known active components. The therapy is administrated at a unique dosing regimen that was found to be effective and advantageous in terms of safety.The product is formulated as an oral suspension, conveniently administrated by the patients at home and not requiring medical staff assistance. This Phase IIb clinical trial aims to evaluate the efficacy of Hamsa-1™ for the treatment of metastatic Castration Resistant Prostate Cancer (CRPC) patients.
The purpose of this research study is to assess outcomes of treatment for early prostate cancer. Current treatments for early (non-metastatic) cancer may cause long-term impairments in the patients quality of life. In this study we will compare the outcomes of patients treated with two alternative brachytherapy (seed implants) techniques using a series of questionnaires.
The objective of this trial is to assess the value of 18F-choline PET/CT for the detection of regional lymph node metastases from prostate cancer. In addition, the investigators want to evaluate whether 18F-choline PET/CT can replace lymphadenectomy for the staging of prostate cancer.
The mechanisms responsible for the development of hormonal refractory prostate cancer (HRPC) have been elusive. Genetic inactivation/loss of the PTEN tumor suppressor gene occurs in 30-60% of advanced prostate cancers and in 20% of the localized form. Researchers hypothesize that PTEN loss is a landmark genetic event in prostate cancer progression into the fatal HRPC form. One consequence of PTEN loss is activation of the oncogenic Akt and phosphorylation of downstream Akt targets including mTOR. mTOR controls many important cellular processes including cell cycle regulation. We propose to evaluate pharmacodynamic assessments of the mTOR inhibitor RAD001 in intermediate and high risk prostate cancer patients in the neoadjuvant setting. Patients will be admitted to 6 weeks treatment with RAD001 10 mg/day followed by either radical prostatectomy or radiotherapy combined with hormonal treatment. Immunohistochemistry with antibodies for phosphorylated p70S6K , pS6, Akt as well as antibodies for VEGF, BCL2 and PTEN in prostate cancer tissues before and after 6 weeks RAD001 treatment will be performed. Additionally, Patients will be evaluated by FDG-PET scan before (as baseline) and after RAD001 treatment. A link between mTOR signaling and glycolysis regulation was established and may provide a mechanism to assess drug-target interaction of RAD001 in prostate cancer. The secondary endpoint of the trial will be to determine the response proportion to RAD001 treatment by assessing time to biochemical failure followed by radiation therapy or radical prostatectomy. The data will be compared to a matched cohort of high and intermediate-risk prostate cancer patients admitted to the same treatments modalities without receiving RAD001.
Participants will be diagnosed with localized prostate or breast cancer and be scheduled to undergo external beam radiation therapy. Participants will either receive a placebo or organic germanium to be taken 5 times a day starting the day of their first radiation and continuing through the 1 month follow-up visit. Weekly Quality of life forms will be completed through the one month follow up visit and then at the 3 month follow up visit. Labs will be done prior to the start of treatment, at the end of treatment and at the one and three month follow-up visits.
The primary objective of this study is to determine the safety and tolerability of a gene-directed enzyme prodrug therapy for prostate cancer. FP253 contains an ovine atadenovirus that expresses the E. coli enzyme purine nucleoside phosphorylase (PNP) under the control of a prostate-directed promoter. PNP converts systemically administered fludarabine (the prodrug) into 2-fluoroadenine (the active agent) at the site where FP253 has been administered (the prostate). This localized conversion is expected to provide organ-targeted chemotherapy that should reduce the systemic side effects associated with classical chemotherapy and also reduce the risk of debilitating damage to tissues surrounding the prostate.
RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This clinical trial is evaluating DNA mutations in predicting the effect of external-beam radiation therapy in patients with early breast cancer, localized prostate cancer, or gynecologic cancer.
This study will use PET scans, which is a type of x-ray test that uses a radiotracer, to see whether these scans may be better able to find places in the body where your prostate cancer may have spread.
Early detection of prostrate cancer and development of metastases. The research will attempt to match the SCM test (structuredness of the cytoplasmic matrix) in lymphocytes as an early cancer detection test using Florescent Activated Cell Sorting (FACS) as a replacement for the CellScan instrument. The test is based on measurement of cellular changes in response to the specific prostate antigen, PSA.
