Filter by:The Trans-Atlantic Prostate Group (TAPG) was established to examine the hypothesis that through a detailed retrospective analysis of outcome in a group of men with clinically localised prostate cancer at diagnosis, variables such as biological, pathological and clinical markers, could be identified that might accurately predict the prognosis of clinically localised prostate cancer.
The prostate gland is a clinically important male accessory sex gland and vital for its production of semen. Prostate cancer (PCa) is now ranked 3th in annual incidence of male cancer and ranked 5th for cancer-related death in men in Hong Kong which accounts for about 10.9 deaths per 100,000 persons. Its incidence is rising rapidly, almost tripled in the past 10 years. Fortunately, with the improvement in awareness of the disease and also increasing use of serum prostate specific antigen for early case identification, many patients are diagnosed at an earlier stage. However, unlike other malignancy, PCa is characterized by its slow progression nature. Therefore, some patients with low grade low volume disease might never suffered from PCa related complications or mortality. As a result, recent year, there is an increase use a more conservative approach, active surveillance (AS), for management of early prostate cancer. The principle of AS is selecting patients with low risk of disease and offered them regular monitoring, instead of radical local therapy, unless patient's cancer was noticed to progressing. By using this approach, patients might avoid possible complications related to treatment. Currently, people could use some clinical parameters, imaging and repeated prostate biopsy to assess and monitor the aggressiveness/ progression of PCa. However, these parameters suffered from defects, such as low correlation to the final PCa pathology or not readily repeatable for patients. Therefore, there is a need to identify more easy, safe and repeatable monitoring of the aggressiveness of prostate cancer. Exosome is genetic materials secreted by cells and could be measured in various body fluid. There are some studies suggested it is a potential marker for PCa diagnosis and monitoring. The aim of this study is to investigate the relationship of urinary exosome and the aggressiveness of prostate cancer.
Prostate cancer (PCa) is the most frequently occurring male cancer in Belgium. After treatment with surgery and/or radiotherapy, almost half of the patients suffer from a tumor recurrence, often diagnosed by an increase in serum tumor marker Prostate Specific Antigen (PSA) within the first few years after primary treatment. However, for salvage therapy to be successful, precise localization of metastases is necessary to determine the most appropriate treatment. In so-called oligo-metastatic disease targeted therapy may still be curative and prevent the disease from spreading to distant locations. Therefore it is of paramount importance to have an accurate tool of medical imaging to localize all possible locations to be treated. Recently, prostate specific membrane antigen (PSMA) has gained interest for PCa-specific imaging. Due to overexpression of PSMA in both primary and metastatic PCa, radiotracers targeting this protein have shown an increased selectivity and sensitivity compared to conventional imaging. The main objective of this phase 3 trial is to determine the position of [18F]PSMA-11 PET/CT within the field of available radiotracers for diagnosis of prostate cancer. For this, the diagnostic performances of [18F]PSMA-11 will be compared to those of the current state-of-the-art radiotracer [68Ga]PSMA-11.
An open-label, multicenter, Phase 1b/2 study to identify the recommended Phase 2 dose and assess the efficacy and safety of BXCL701 administered orally, as monotherapy and in combination with PEMBRO, in patients with mCRPC. Patients enrolled in the Phase 2a portion of the study will have either Small Cell Neuroendocrine Prostate Cancer(SCNC)(Cohort A) or adenocarcinoma phenotype (Cohort B), while the Phase 2b randomized portion of the study will enroll only the histologic subtype(s) showing preliminary evidence in Phase 2a. The study will also assess other efficacy parameters, such as rPFS, PSA PFS, OS, and DOR, as well as the safety of the combined treatment. The study will consist of three components.
Radical radiation therapy for prostate cancer is a common treatment that has shown to improve clinical outcomes in a post-operative setting. However, radiation therapy after surgery poses a greater risk for bladder and rectum injury for patients with prostate or bladder cancer. For prostate cancer patients, the risk is further amplified when pelvic nodes are part of the target irradiated volume. For bladder cancer patients, the risk of injury increases when more of the bladder is part of the target volume. Using an adaptive radiation therapy approach allows for correcting any shifts in the target volume. ART approach uses images from treatment to adapt the treatment plan. This study will use Adaptive Radiation Therapy for patients who receive pelvic nodal radiotherapy for either prostate or bladder cancer. Their treatment plans will adapted using MRI scans and CBCT scans taken during their first week of radiotherapy to account for any shifts in the target volume. The purpose of this study is to evaluate the feasibility of ART approach and its and on treatment plan quality metrics for pelvic radiotherapy. Acute and late toxicities will also be evaluated. 40 participants (minimum of 10 bladder cancer patients) will be enrolled. The participants will be followed for a period of 5 years post radiation therapy, during which they will have PSA as per standard practice, along with follow-up questionnaires (EPIC for prostate cancer patients and BUSS for bladder cancer patients).
Our objective in this study is to identify an optimal ultrasound spectroscopy parameter that can be used as an early predictor of pathological complete or partial response in men with prostate cancer and men and women with rectum and head and neck cancers receiving treatment radiotherapy. We have previously demonstrated that high-frequency ultrasound and spectroscopy, and recently conventional-frequency ultrasound and spectroscopy may be used to detect cell death in vitro, in situ and in vivo. The method can detect different forms of cell death and has been demonstrated to be sensitive to apoptotic, necrotic and mitotic cell death. The main goal, as described above, is to select the best ultrasound spectroscopy parameter to use as an early predictor of pathological complete response
Firefighters, police, military personnel and pilots are all shown to have a higher incidence of prostate cancer than the general population. A possible explanation for this is that these four groups of employees need regular mandatory health-checkups. If these checkups increase the chances of having a PSA or DRE performed one could expect the workers in question to have a higher probability than the general population of being diagnosed with prostate cancer. If this is the case the four groups should have cancers that are lower grade and have better survival. The investigators wish to examine this by comparing the four groups with a control group made up of all other workers with regards to prognostic factors at the time of diagnosis and survival rates. This will be done by extracting data from the Cancer Registry of Norway, coupled with employment data from Statistics Norway. This study is also a part of a project on cancer in firefighters. If the prostate cancers in firefighters differ significantly from the other three specified groups, this could point to an exposure specific for firefighters, e.g. fire smoke, as an etiologic factor.
Prostate cancer (PC) is highly prevalent worldwide and is currently the 3rd most commonly diagnosed prostate cancer in Hong Kong male population with more than 1600 new cases diagnosed per year. However, the current use of serum PSA as a diagnostic marker is unsatisfactory. Many patients has elevated serum PSA is actually due to other causes and also the level of serum PSA do not correlate with the staging and grading of prostate cancer. Moreover, the current risk stratification system, based on PSA, clinical staging and Gleason score is of only limited value, as a significant proportion of patients with high-risk nonmetastatic PC have incurable disease due to locally advanced and/or occult metastasis,, whilst others with indolent disease may never suffer morbidity or mortality from PC. Therefore, in order to improve patient management and outcome, there is a need to identify newer markers and also validate some potential markers in Chinese population.
Under the prostate cancer screening protocol of the project 'Prevention of Obesity-related Cancers', men with elevated PSA with higher prostate cancer risk (PSA 4-10 ng/mL with high Prostate Health Index (PHI) ≥35, or PSA>10 ng/mL) will be offered a prostate biopsy. In the current study, we would like to offer all screened men with elevated PSA in the range of 4-50 ng/mL a biparametric non-contrast MRI prostate (screening protocol) for any suspicious lesion in the prostate. If there is MRI lesion seen, additional targeted biopsies can be performed on top of the standard systematic prostate biopsies. It has been shown in a clinical Caucasian cohort that doing MRI-targeted biopsies resulted in improved detection of clinically significant prostate cancer compared with standard systematic biopsies. In this study investigators would like to investigate the benefits of adding MRI prostate and MRI-targeted biopsy in the diagnostic pathway for prostate cancer in a screened cohort of Chinese men at risk of prostate cancer.
The purpose of this study is to learn the long term efficacy and side effects associated with utilizing Stereotactic Body Radiation Therapy (SBRT) radiation for prostate cancer utilizing the Elekta Versa or Agility System. SBRT uses advanced imaging techniques to deliver targeted radiation to a tumor. The Elekta Versa and Agility Systems are approved by the Food and Drug Association (FDA) for SBRT treatment of cancer. Traditional External beam radiation therapy (EBRT) for prostate carcinoma is typically done over the course of approximately 42-45 daily treatments SBRT is a way to condense this treatment into a course of 5 treatments, delivering more dose per day.
