Filter by:The purpose of the study is to evaluate whether state-of-the-art technologies such and next generation sequencing and drug sensitivity and resistance testing of patient derived tumour tissue can facilitate research translation and improve outcome of urologic cancers.
A two-arm randomised controlled trial in patients receiving post-prostatectomy radiotherapy in the adjuvant or salvage setting, with patients randomised to receive daily ProSpare (obturator) guided IMRT or Centre standard (non-obturator) guided IMRT.
The present phase I trial evaluates the feasibility of a postoperative stereotactic hypofractionated external beam radiation therapy delivered in patients who underwent radical prostatectomy with adverse pathological features or early biochemical failure. Modern computer-driven technology enables the implementation of ultra-high hypofractionated Image-Guided Radiotherapy (IGRT) safely. Eligible patients for this study are those with: - Adenocarcinoma of the prostate treated with radical prostatectomy (any type of radical prostatectomy is permitted including retropubic, perineal, laparoscopic or robotically assisted; there is no time limit for the date of radical prostatectomy) - Pathologic (p)T3 disease, positive margin(s), Gleason score 8-10, or seminal vesicle involvement - Undetectable post-radical prostatectomy PSA that becomes detectable and then increases on 2 subsequent measurements (PSA of > 0.1 - ≤ 2.0 ng/mL) - Life expectancy: 10 years - ECOG performance status of 0 -1 - No distant metastases, based on the following workup within 60 days prior to registration - Magnetic resonance imaging (MRI) of the pelvis - PSMA/Choline Positron Emission Tomography (PET) to exclude systemic disease in patients with biochemical recurrence - Patients can be on androgen deprivation therapy - Ability to understand and willingness to sign a study-specific informed consent prior to study. Patients enrolled in the study will undergo image-guided, volumetric intensity-modulated arc radiotherapy (IGRT-VMAT) with state-of-the-art treatment-planning and quality assurance procedures with emphasis on normal tissue sparing and delivery accuracy via the use of devices that ensure stability and beam location reproducibility.
Prostate cancer is the most common non-skin cancer diagnosed among men and the second leading cause of male cancer deaths in the United States. In 2013, it is estimated that 29,270 men have died from prostate cancer. Although radiation and surgery are quite effective for localized disease, there is no effective cure for men who present with metastatic prostate cancer as the 5-year relative survival rate is only 28%. Currently, androgen deprivation therapy (ADT) via medical or surgical castration is the standard first-line therapy in men with metastatic disease but castration-recurrent prostate cancer (CRPC) eventually emerges with a median time of 18-24 months. Once CRPC develops, secondary hormonal manipulation, chemotherapy, and immunotherapy are marginally effective. Given the dismal prognosis of metastatic prostate cancer, new ideas and novel approaches must be explored to improve the clinical outcome. In this regard, recently emerging data suggest that local tumor control may enhance the effectiveness of subsequent systemic therapies. Therefore, in this proposal, the investigators have designed a Phase I/II study in which they will prospectively evaluate the safety and feasibility of cytoreductive prostatectomy in men with newly diagnosed mPCa.
In this study, the investigators aim to establish the prostate cancer active surveillance prospective cohort in our institution, and finally investigate the 5 year rates of reclassification during active surveillance as the primary endpoint of the current study.
The purpose of this study is to evaluate the dose of High Dose Rate (HDR) brachytherapy chosen for this study as well as a commonly used alternate form of brachytherapy called low dose rate (or seed) brachytherapy. Investigators would like to understand how these treatments control the prostate cancer and look at their short and long term treatment related side effects. The dose of radiation for HDR brachytherapy for this study has been changed since the study started. Other studies using the dose of radiation for HDR brachytherapy that was originally chosen for this study (Arm 2) found that this dose of radiation may be linked to a greater chance of the cancer coming back in the prostate. Therefore since March 2020, for new participants entering the study, a new HDR brachytherapy arm with a higher amount of radiation given over two doses will be tested in this study
The purpose of this study is to collect long term safety data in subjects who are continuing to derive clinical benefit from treatment with Enzalutamide from the subjects participation in an enzalutamide clinical study sponsored by Astellas or Medivation (i.e., parent study) which has completed, at a minimum, the primary analysis or the study specified evaluation period.
Prostate cancer (PrCa) is one of the commonest cancer in men in the Western world. In the United Kingdom (UK), there were over 52,000 new cases diagnosed in 2016-2018 and a lifetime risk of 1 in 8. Research studies have identified several genetic changes that are thought to increase the risk of developing prostate cancer. Some of these genetic changes occur in deoxyribonucleic acid (DNA) repair genes. The BARCODE 2 trial is formed of two parts that aim to investigate how having genetic changes in DNA repair genes can affect response to carboplatin treatment in patients with metastatic castration resistant prostate cancer (mCRPC). In part 1 of the study, the investigators will invite men with mCRPC who have not had genetic testing before to join the study by initially undergoing genetic screening within the study. The DNA repair gene mutation carrier status of enrolled patients will be assessed using a gene panel. If a pathogenic mutation is confirmed in one of these genes, patients will be given the option to proceed to part 2 of the study. In part 2 of the study, men with mCRPC who are known to be carriers of a mutation in DNA repair gene(s) will be assessed for eligibility for treatment on the study with carboplatin chemotherapy. The aim of the study will be to determine how patients with mCRPC and a germline mutation in a DNA repair gene(s) respond to platinum chemotherapy. This study will help researchers to investigate platinum sensitivity of prostate tumours that have developed due to a germline mutation in a DNA repair gene. This study will provide data to use in a larger clinical trial of platinum chemotherapy based on patients' germline genetic signature and/or tumour genetic profile.
This randomized phase II trial studies how well androgen receptor antagonist ARN-509 works with or without abiraterone acetate, gonadotropin-releasing hormone agonist, and prednisone in treating patients with high-risk prostate cancer undergoing surgery. Androgen can cause the growth of prostate cancer cells. Hormone therapy using androgen receptor antagonist ARN-509, abiraterone acetate, and gonadotropin-releasing hormone analog (GnRH agonist) may fight prostate cancer by lowering the levels of androgen the body makes. Prednisone may either kill the tumor cells or stop them from dividing. Giving androgen receptor agonist ARN-509 with or without abiraterone acetate, GnRH agonist and prednisone may work better in treating patients with prostate cancer.
