Filter by:Rationale: Understanding the mechanisms of enzalutamide as an androgen receptor inhibitor in early prostate cancer could lead to improved patient selection for treatment. Objective: To study the effects of enzalutamide on surgical margin status and AR / DNA interaction and gene expression. Intervention : Men with localized prostate cancer will undergo an additional set of targeted tumor biopsies and will be subsequently treated with 3 months of enzalutamide. The prostatectomy specimen will be additionally sampled, ex vivo.
Retrospective Review Study for Prognostic Transcriptional Output Related to Androgen Receptor Expression in Patients Treated for High Risk Prostate Cancer with Proton Therapy
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.
This feasibility exploratory study objective is to assess the ability of combined MRI BOLD and 18F-MISO PET imaging to visualize tumor hypoxia compare to histological results obtained after radical prostatectomy in order to, in time, be able to identify patient with bad prognostic and to offer them the best therapeutic strategy.
This high resolution MRI (hrMRI), along with stand MRI (sMRI) will be obtained at baseline and again in approximately 1 year in patients on prostate cancer active surveillance. Changes in lesion size and ADC values will be assessed on the serial studies. This study evaluates the hypothesis that hrMRI will detect changes that sMRI cannot detect and that these changes will correlate with prostate cancer progression as determined on prostate biopsy.
This is a long-term prospective registry study to determine whether Prolaris testing in patients with favorable intermediate risk prostate cancer influences physician management decisions toward conservative treatment in patients with Prolaris low-risk scores without negatively impacting patient oncologic outcomes, thereby sparing low-risk patients from unnecessary treatments and associated side-effects.
The purpose of this study is to see if eating vitamin D, omega 3 and turmeric (curcumin) slows the growth of prostate cancer in men on active surveillance.
The aim of this study was to determine the kinetics of perioperative circulating DNA in three types of cancer. This first step will enable further studies comparing the potential impact of certain techniques or anesthetic products on cancer surgery.
