Filter by:The current standard for Prostate Cancer (PCa) detection remains taking 10-12 systematic biopsies of the prostate. This approach leads to overdiagnosis of insignificant PCa on the one hand and underdiagnosis and undergrading of significant PCa on the other. multiparametric Magnetic Resonance Imaging (mpMRI) has seen an increasing uptake in the clinics for biopsy targeting, but the value in biopsy naive patients remains controversial. With Contrast Enhanced UltraSound (CEUS) cancer induced neovascularisation can be visualised with the potential to improve ultrasound imaging for prostate cancer detection and localisation significantly. The past years numerous studies have been performed with CEUS, all basing their results on subjective judgement of the investigator. To overcome these difficulties CEUS quantification techniques have been used with encouraging first results. These imaging techniques have been proposed to improve the yield of prostate biopsies and possibly replacing systematic biopsies. In this trial mpMRI imaging and CEUS + quantification are performed before primary biopsy. Using a fusion device, targeted biopsies are taken from predefined MRI lesions and CEUS lesions, together with standard systematic biopsies in the same patients by separate blinded clinicians. The main outcome measure is the per-patient (significant) prostate cancer detection rate for each of the biopsy regimens.
The main objective of study is to describe the priorities of elderly patients (70 years and over) undergoing a first medical treatment for cancer, at initiation of treatment and after 3 months of treatment. The main criterion is a prioritization of 4 items per patient from a list of 8 expectations regarding the objectives of their treatment: treatment efficacy, life expectancy, autonomy, daily activities, social activities, heaviness of treatment, toxicity, economics.
Add-Aspirin aims to assess whether regular aspirin use after standard curative therapy can prevent recurrence and improve survival in individuals with non-metastatic common tumours. The question will be assessed in four different tumour types (breast, colorectal, gastro-oesophageal and prostate) by means of parallel cohorts within an overarching trial protocol. Eligible participants will be randomly assigned (double-blind) to either aspirin 100mg, aspirin 300mg or a matched placebo, to be taken daily for at least 5 years. Disease recurrence and survival will be assessed, along with adherence, toxicity, and other potential effects of aspirin (eg. cardiovascular). There is a large body of evidence indicating that aspirin has anti-cancer effects. Meta-analyses of cardiovascular trials of aspirin have shown short-term effects on cancer mortality and a decrease in risk of metastases, suggesting a role for aspirin in the treatment as well as prevention of cancer. Additionally, large observational studies of individuals taking aspirin after cancer treatment have shown improved disease-specific and overall mortality for specific tumour types. In the treatment setting, the risks of side effects associated with aspirin are expected to be outweighed by potential benefits. However, this has not yet been assessed in a randomised trial. As a low cost, generic and widely available drug, which is generally safe, if aspirin is shown to be effective, it could have a huge impact on cancer outcomes globally.
In this open randomized controlled trial, we seek to study whether prostate cancer screening using multiparametric prostate magnetic resonance imaging (mpMRI) improves the detection rate of clinically-significant prostate cancer (defined as Gleason score ≥7 on prostate biopsy) compared with prostate cancer screening using prostate-specific antigen (PSA). The current paradigm of prostate cancer screening relies upon an initial PSA blood test, with subsequent investigations driven by the serum PSA level. This model has proven highly controversial due to the inability of PSA level to discern between indolent and aggressive forms of prostate cancer. As a result, numerous government-sponsored bodies have recommended against PSA screening. Evidence suggests that prostate cancer screening has led to an increased proportion of men being diagnosed with potentially curable prostate cancer. However, due to the inability of the PSA level to accurately distinguish patients with indolent and lethal forms of prostate cancer, it has led to a significant rate of over-diagnosis of indolent disease. Magnetic resonance imaging has been gaining an increasingly large role in the management of patients with clinically-localized prostate cancer including diagnosis in patients with abnormal PSA levels, monitoring of patients on active surveillance and staging prior to definitive interventions. MRI-based prostate cancer risk assessment has been shown to better distinguish between clinically-significant and insignificant tumors than PSA test. Therefore, a randomized controlled trial of MRI-based prostate cancer screening and PSA-based prostate cancer screening is warranted.
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.
