Filter by:Background: EP0057 consists of a sugar molecule cyclodextrin linked to a chemotherapy drug called camptothecin. The combined molecule or "nanoparticle drug conjugate" travels through the blood. Once inside cancer cells, the chemotherapy drug is released from the molecule. Olaparib is a drug that may stop cancer cells from repairing the DNA damage caused by chemotherapy. Researchers want to see how safe it is to give EP0057 and olaparib together and to see how well the combination treats a specific type of lung cancer called small cell lung cancer (SCLC). Objectives: To test the safety and maximum dose of EP0057 and olaparib together. To test how well they treat small cell lung cancer. Eligibility: Adults 18 and older with small cell lung cancer. Design: Participants will be screened with standard cancer care tests. Participants will get the 2 study drugs in 28-day cycles. EP0057 will be given every 2 weeks, through a small plastic tube in an arm vein. Olaparib will be taken by mouth twice a day most days. Participants will keep a pill diary. For Cycle 1, participants will have 3 visits. All other cycles will have 2 visits. At study visits, participants may have: - Blood and hair samples taken - History and Physical exam - Questions about health and side effects - Pregnancy test - Optional tumor biopsy where a piece of tumor is removed by needle after numbing the skin. - CT scan - Injection of EP0057 (twice per cycle) - Olaparib prescription <TAB> Participants will have a follow-up visit 4 weeks after finish taking the drugs. They will have a physical exam and blood tests. They may have a tumor biopsy. The study team will call the patient every 3 months for follow up after completing the study treatment.
ProtoChoice-P is a prospective multicenter trial to evaluate proton therapy in patients suffering from prostate cancer. Primary aim of the study is a decrease of moderate or severe genito-urinary or intestinal side effects (Common Terminology Criteria for Adverse Events (CTCAE) 4.0 grade 2 or higher) by the use of proton therapy. Secondary endpoints contain assessment of quality of life, biochemical recurrence and recurrence free survival as well as overall survival and economic comparison between photon and proton therapy.
The purpose of this study is to evaluate if a diet with a high content of phytoestrogens can slow down the prostate tumor proliferation. Phytoestrogens are found in food items such as soy, rye, and seeds. Two hundred thirty men with prostate cancer will be included in the study and followed until surgery (at least 6 weeks). Half of the study participants will receive general information about healthy food choices and a package of foods with high content of phytoestrogens to add to their food. The other half will get the same information but not receive the food-package.
Though the pathogenesis of prostate cancer (PCa) is still obscure, it has been reported, by investigators previous studies and some other researches, that PCa is often combined with tissue inflammation which is closely related to prostate specific antigen (PSA) level. Inflammation could play an important role in the process of occurrence and development of PCa, however the mechanism is unknown. Inflammatory cytokines could not only mediate inflammatory reactions, but also participate in the growth, proliferation, invasion and progression of tumor cells. It has been found that non-steroid anti-inflammatory drugs (NSAIDs), such as aspirin, can effectively prevent several inflammation related tumor, and coincidentally, PCa is also closely associated with inflammation. Moreover, latest researches demonstrated that hormone therapy could induce tissue inflammation in PCa, in which a large quantity of immune B cells were attracted into the focal and then a lot of cytokines, such as IKK-β, NF-κB, were released. These cytokines could inhibit apoptosis and promote the growth of tumor cells, which might be a possible mechanism for long-term inflammatory infiltration inducing the occurrence of PCa and the transformation to castration-resistant prostate cancer (CRPC). Based on these proofs, investigators presume it could be possibly an effective way to prevent the occurrence of PCa and the transformation from androgen-dependent prostate cancer to CRPC by means of long-term oral aspirin. In this study, investigators intend to explore the possible effect of anti-inflammatory therapy on the progress of transformations from inflammation to PCa and from androgen-dependent prostate cancer to CRPC. Investigators plan to conduct both clinical trials in four groups, including the control group, the NSAIDs group, the antibiotics group and the NSAIDs+antibiotics group, and a basic experiment in vitro to assess the effectiveness of anti-inflammatory drugs and elucidate the specific molecular mechanism.
This is an open-label positron emission tomography/computed tomography (PET/CT) study to investigate the diagnostic performance and evaluation efficacy of 68Ga-NOTA-BBN-RGD in prostate cancer patients. A single dose of 111-148 Mega-Becquerel (MBq) 68Ga-NOTA-BBN-RGD will be injected intravenously. Visual and semiquantitative method will be used to assess the PET/CT images.
The aim of this research project is to assess the feasibility and safety of carbon-ion radiotherapy (CIRT) for the treatment of in Chinese localized prostate cancer
1. The overall objective of the study: By evaluating the curative effect of CSAP in localized prostate cancer, locally advanced prostate cancer and metastasis advanced prostate cancer, and the change of state in cellular immunity and humoral immunity before and after CSAP. Validate the clinical therapeutic effect of all kinds of prostate cancer, as well as the change of immune status before and after CSAP. 2. The main content of the study: 1. Included in the samples are patients in hospitals for CSAP. The sample capacity are planned to be 80. The main purpose of the study is to observe the overall survival rate , disease free survival rate, the progress time of the PSA biochemical recurrence as well as the disease progress time. 2. Measure the change of concentration in peripheral blood T lymphocyte subsets (CD3 + T, CD4 + T, CD8 + T, CD4 + / CD8 + T, NK cells) and regulatory T cells before and after cryoablation within 1 month, 3 months and 6 months. 3. Measure the change of concentration in peripheral blood IFN-1, IL-4, IFN-1/IL-4 ratio (Thl/Th2 ratio), and detect the secretion of CD4 + Th tumor-specific IFN-l and the activity of tumor-specific killer CD8 + CTL before and after cryoablation within 2 weeks and 1 month. 4. Before cryoablation, detect the expression and distribution of Follistatin-Like1 (FSTL-1), Besides, verify the connection between the number and activation ratio of tumor local dendritic cells (DC) and the FSTL-1, evaluating the cryoablation effect on the immune response.
MR (Magnetic Resonance Imaging) - based IGRT (image-guided radiotherapy) for patients with prostate carcinoma.
As prostate cancer progresses, tumor cells dissociate and enter the bloodstream. Considered a "liquid biopsy," these circulating tumor cells (CTC) can show how a patient's cancer evolves and responds to treatments. The purpose of this study is to determine whether sequentially analyzing the expression of tumor markers in circulating tumor cells in newly diagnosed metastatic hormone-sensitive prostate cancer patients can predict the outcome of these patients.
The evaluation of the radiological changes in localised or locally advanced prostate cancer after androgen deprivation therapy and external beam radiotherapy using multi-parametric MRI (multi parametric magnetic resonance imaging) and VERDICT (Vascular, Extracellular and Restricted Diffusion for Cytometry in Tumours) sequences.
