Filter by:To compare the toxicity, rate of local control, biochemical failure rate and quality of life of three different radiotherapy techniques (moderate hypofractionation, stereotactic body radiotherapy (SBRT) and standard radiotherapy plus 2 fractions of SBRT (BOOSTER)
A randomized controlled open-label trial in patients with high risk prostate cancer. Eligible and consenting patients will be randomly allocated to receive stereotactic body radiotherapy (SBRT) boost to prostate or conventional radiotherapy boost to prostate in 1:1 ratio. Prostate radiotherapy boost will be administered after standard pelvic radiotherapy. Subjects will be followed for 24 months post radiation treatment for Quality of Life assessment and toxicity.
Background: Prostate cancer is one of the most common cancers for men in the U.S. There are some new ways to take pictures of the cancer. There are also new ways to use image-guided biopsy and therapy. These could help manage prostate cancer. Researchers want to study how imaging can provide a profile of prostate cancer. They want to collect data to make diagnosis and treatments better. Objectives: To gather data about the radiological and clinical course of prostate cancer. To study imaging-based biomarkers of prostate cancer. Eligibility: Men ages 18 and older with diagnosed or suspected prostate cancer Design: Participants will give permission for researchers to use their medical history and records. Their data will be reviewed, collected, and analyzed. These include results of their tests and scans. Sponsoring Institution: National Cancer Institute
Prostate cancer (PCa) is ranked 3rd in annual incidence of male cancer and ranked 5th for cancer-related death in men in Hong Kong which accounts for about 9.1 deaths per 100,000 men in 2011. Its incidence is rising rapidly, almost tripled in the past 10 years. In Hong Kong, the two main screening methods for PCa are digital rectal examination (DRE) and serum prostate-specific antigen (PSA) level blood test, and the gold standard of diagnosis of PCa is transrectal ultrasound (TRUS) with prostate biopsy. For those who diagnosed with PCa, there are different kinds of managements depending on patient's age group and disease stage. Watchful waiting is for older patients who presents with low-risk prostate cancer. And active surveillance is applicable to patients who are eligible for potentially curative management. While radiotherapy or radical prostatectomy are recommended as curative management for early stage PCa, androgen deprivation therapy (ADT) is the main treatment modality for advanced or recurrent prostate cancer. Advanced prostate cancer that recurrence is called castration refractory prostate cancer (CRPC). There are many new agents, including second line hormonal therapy, chemotherapy, androgen biosynthesis inhibitors, immunotherapy, bone targeting agents etc., available for the further management. In this study, investigators would like to establish a local prostate cancer registry to facilitate the collection of clinical information and outcomes of prostate cancer management. Hopefully, this registry can provide information regarding the epidemiology, natural history, and treatment outcomes of local prostate cancer. The information would be helpful for research, public education, health care planning and also international collaboration. Ultimately, patients and public would be benefited from these works.
This study was undertaken to evaluate bone response in metastatic prostate cancer patients treated with Enzalutamide with or without Zoledronic Acid in combination with luteinizing hormone-releasing hormone (LHRH) analogue with the use of Whole Boby (WB) DW-MRI.
This is an Investigator Initiated, non-commercial, single center, non-randomized, single arm, open label pilot study on 194 patients. The patients are affected by prostate cancer but in two different clinical settings. The first group is characterized by patients who are going to be operated of radical prostatectomy and they will undergo the study imaging preoperatively. The second group experiences biochemical relapse after primary treatment.
Phase A: To describe and to determine the maximum standardised uptake values (SUV) in prostate specific membrane antigen positron emission tomography (PSMA-PET) before ADT and 7, 14 and 28 days after ADT. Phase B: To validate phase A results by comparing the PSMA-PET findings to histopathological analysis of regional lymph nodes acquired from radical prostatectomy specimens. PSMA-PET is done before ADT and at maximum SUV defined by the phase A.
The main objective of the phase I/II trial is to determine the safety and efficacy of a single fraction SBRT at a dose of 19 Gy in patients with localized prostate cancer.
The main idea behind MICRO-LEARNER is to provide new insights about the response of healthy tissues to radiation by using information from the micro-environment obtained by biological measurements and imaging. This new knowledge will be included in current available predictive models of radio-induced toxicity, thus allowing to add unique biological characteristics of patients to dosimetry and treatment/clinical related variables. MICRO-LEARNER focuses on prostate cancer (PCa) and head-and-neck cancer (HNCa). For both cancers, radiotherapy is effectively used as curative treatment, in single modality or within a multidisciplinary approach including surgery (PCa) and/or chemotherapy (HNCa). Prediction and reduction of radio-induced side effects are becoming a priority: for PCa, high survival rates should be accompanied by a very low rate of moderate/severe toxicities; for HNCa, there is the need to tailor radiation dose according to disease recurrence risk profile. The shared aim of both cancers is to balance the improvement in outcome with a well-tolerated toxicity profile. Recent research indicates that the intestinal/salivary bacteria are strongly suspected of being very important in mediating the response to inflammation and lesions. Although their balance deeply changes during radiotherapy, studies done so far in the field of the microbiota-host relationship in radiotherapy have not addressed their role in insurgence of radiation toxicity. In this study, the investigators will assess how microbial populations evolve and how this influences the host and radiation induced toxicity in a significant number of patients. Moreover, the individual response at the tissue microstructure level, through analysis of images with advanced bioengineering techniques, will be determined. Results from this research, besides suggesting new ways to predict patients at risk of relevant side-effects, may also suggest possible treatments to change the baseline microbiota of patients at high risk or to modify it during therapy, in order to mitigate toxicity. Understanding the microbiota-radiotherapy interaction may thus lead to novel, effective and inexpensive ways of assessing and managing complications of cancer treatment.
The aim of this project is to determine whether androgen deprivation therapy (ADT) decreases left ventricular function in prostate cancer patients. If found successful, this may lead to improved cardiovascular health via treatment and/or lifestyle interventions in prostate cancer populations.
