Active clinical trials for "Prostatic Neoplasms"

Many prostate cancer patients required the use of androgen deprivation therapy (ADT) for the control of disease. In this study, the investigators aim at assessing the different in various parameters between PCa patients received ADT and those without ADT. 60 patients diagnosed with PCa and planned for hormonal therapy will be recruited for study (active arm) and 30 PCa patients that do not planned to receive hormonal therapy (based on the clinical assessment by the investigators) will be recruited as control arm. After written consent obtained from study subject, a series of investigation will be arranged to assess the following aspect of the subjects before the commenced of ADT: General condition - symptoms, general health, Body composition - BMI and body composition Mental state assessment by Mini-Mental State Examination (MMSE) Blood for fasting lipid, sugar, hsCRP and other hormones (about 15cc) Cardiovascular status - BP, Ankle-brachial index (ABI), Arterial stiffness, ECG, Bone status - bone mineral density by dual-energy X-ray absorptiometry (DEXA) scan The assessment of general condition, body composition, blood parameter and cardiovascular status will be performed every 26weeks +/- 1 weeks for two years. Bone density measurement will be performed every 52 weeks +/- 2 weeks. Appropriate medical referral will be made if subject was found to have abnormal metabolic or cardiovascular parameters.

The purpose of this study is to investigate the prevalence of tissue homologous recombination repair (HRR)-related gene mutations (positive/negative/Variant of uncertain significance (VUS)), clinical outcome such as prostate-specific antigen-progression free survival (PSA-PFS), overall survivals (OS) and treatment pattern in mCRPC patients. <Methods> Study design: multi-center, prospective cohort study Data Source(s): In this study, 155 patients (expected recruitment patients: maximum 205 patients) will be enrolled from approximately 20~30 sites in Japan. Study Population: mCRPC patients who diagnosed between 2014 and 2018. Exposure(s): N.A Outcome(s): Prevalence of tissue HRR-related gene mutations, clinical outcomes such as Over survival and PSA-PFS, Treatment pattern Sample Size Estimations: The target population is 155 patients based on the prevalence of HRR-related genes (BRCA1, BRCA2 and ATM) which is reported in previous global study (PROfound study). Statistical Analysis: This study is not intended to verify specific hypotheses, and the results are evaluated descriptively. There is no plan of interim analyses before the final analysis.

Retrospective monocentric analysis performed on patients treated with salvage HIFU for isolated macroscopic recurrence in the prostatic bed after radical prostatectomy and salvage or adjuvant EBRT. The oncological outcomes (treatment failure-free survival, progression-free survival), the adverse events and urinary incontinence will be evaluated.

Investigators are building an empirical evidence base for real world data through large-scale replication of randomized controlled trials. The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.

18F-PSMA-1007 is a new radiopharmaceutical for the detection of prostate cancer with potential benefits over the registered 18F-Fluciclovine (Axumin). The main potential benefit is the higher detection rate of PSMA compared to Fluciclovin in the low PSA range. It may therefore be more sensitive in detecting local disease in case of biochemical recurrens. The investigators aim to compare the detection efficacy of 18F-PSMA-1007 to 18F-Fluciclovin in prostate cancer patients with biochemical recurrence (PSA levels 0.2-5 ng/ml).

This is a pilot phase 2 single-arm study, of men with metastatic castration-resistant prostate cancer (mCRPC). Patients will be treated with any of the approved life-prolonging therapies: abiraterone 1000 mg daily plus prednisone 5 mg (or dexamethasone 0.5 mg) daily, enzalutamide 160 mg daily, or docetaxel 50 mg/m2 every two weeks or 75 mg/m2 every three weeks.

In 2018 the Unity MR-linac was approved for treating patients with online magnetic resonance (MR)-guided radiotherapy. With the MR-linac it is possible to get real-time MR images with high soft tissue contrast, adapt the radiotherapy plan and subsequently irradiate at each treatment fraction. Patients with prostate cancer is one of the patient groups referred for this new treatment and potentially they will benefit with decreased margins around the tumour and increased local tumor control rates. The acute toxicity is important when evaluating treatment tolerability. A prospective longitudinal observation of the acute treatment toxicity to online MR-guided radiotherapy is therefore essential in the evaluation of this new technology. Patient-reported outcomes (PRO) are disease symptoms and treatment toxicity reported directly by patients themselves without clinician interpretation. Several studies have indicated that clinicians tend to underreport the incidence and severity of patient symptoms, thus a systematic use of PROs in clinical trials can provide valuable evidence to the clinicians. As online MR-guided radiotherapy (MRgRT) is a new technology there is limited research worldwide on patient-reported symptoms and quality of life. The objective of this study is therefore to prospectively investigate the patient-reported acute toxicity and changes in quality of life during and after online MR-guided radiotherapy.

Prostate cancer is a type of cancer that can occur in men, especially in the fifth and sixth decades of their lives, and various side effects occur depending on the treatments applied in the diagnosed patients. The treatments applied and the decreased level of physical activity also cause a decrease in the quality of life. Recent studies have focused on treatment-related side effects. Before treatment planning, there is a need for clinically validated clinical evaluations specific to prostate cancer patients in order to determine the current status of the patients or to measure the effectiveness of the treatment applied. In addition, tests with a minimal detectable amount of change will be guiding in order to understand that the effectiveness of the applied treatment is significant. The aim of our study is to investigate the validity, reliability and minimal detectable changes of the two-minute walk, sit up and time up and go tests validated in different disease groups for patients with prostate cancer.

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.
