We investigate the association between Triglyserid-Glucose(TyG) index and prostate cancer in patients undergoing radical prostatectomy.
This study aims to assess the impact of a group intervention combining self-hypnosis and self-care techniques on prostate patients' well-being. More specifically, the investigators want to investigate the effects of that intervention on sleep, fatigue and emotional distress of the patients.
This study examines the effect of a five-year multifactorial lifestyle intervention in the Oslo diet and antismoking study on long-term cancer risk. In 1972-1973, 1232 men with high cardiovascular risk profile were randomised to intervention including cholesterol lowering diet, weight loss and antismoking advice, or control (1:1). This study examines the effect of the intervention on 43-year cancer incidence and mortality.
Prostate cancer is the most common cancer in men over 50 years old and the third leading cause of cancer death. Because of the variety of prostate cancers, different treatments exist. Several criteria guide this management in daily practice: PSA level; TNM stage (digital rectal examination, trans-rectal ultrasound and classical visual imaging) and pathological differentiation with the Gleason score, to which can be added other prognostic criteria: growth and doubling time of the serum PSA, number of positive biopsies and percentage of cancer lesions by biopsy. Functional imaging by PET and MRI is increasingly used in daily clinical practice to characterize prostate cancer, either during initial discovery or during recurrence. In this context, it is the qualitative visual analysis that is mainly used. Quantitative image analysis could add new criteria to guide patient management. Consequently, the objective of this study were: - Optimization of 18F-choline PET/CT Acquisition in Prostate Cancer - Comparison the quantitative parameters obtained by 18F-Choline PET / CT and both perfusion MRI and histological parameters.
Prostate cancer (CAP) is one of the most common malignancies in men, both in Western countries and developing countries. Radiation therapy (RT) is an important therapeutic option. New technologies (3D, IMRT, IGRT, VMAT) have been introduced in the last decades, with a progressive improvement of clinical outcome. However, in many countries the only treatment option is the traditional 2D technique based on standard simulation. The indications for field definition in this treatment are still based on expert's opinions. The aim of this analysis is to propose new indications for 2D fields definition based on three-dimensional simulation in a population of patients with CAP. Twenty patients with CAP consecutively treated with RT in our center were identified. Patients underwent CT-simulation in supine position. Pelvic MRI images were fused with CT-simulation images. In this way, delineation of the prostate and seminal vesicles was performed on MRI images. Clinical Target Volume definition (CTV) was performed according to EORTC guidelines simulating 4 different categories: low-risk CAP, intermediate-risk CAP, high-risk CAP without involvement of the seminal vesicles, and high-risk CAP with involvement of seminal vesicles. The Planning Target Volume (PTV) was defined by adding a margin of 10 mm to the CTV in all directions. For each patient, 8 treatment plans were calculated. In particular, for each of the 4 categories of risk, 2 treatment plans were calculated by using a cobalt source or 10 MV photons. Treatment plans were calculated using the box technique. Progressive optimization was realized with an iterative procedure by evaluating the three-dimensional dose distribution. Once the final plan was achieved (respecting the PTV constraint: D98 > 95%), distances of the fields edges from a set of reference points were measured.
A specific scale allowing the measure of anxiety of patients with protate cancer has been designed and validated but the French version needs to be validated. This study aims at validating the French translation of this scale.
The current study aimed to develop and assess an easy-to-use, highly accessible mobile and web-based application intervention to reduce sedentary behavior and increase physical activity in the hope of reducing the side effects of treatment and improving quality of life for the 13,000 or more prostate cancer survivors who are prescribed ADT each year in Canada. The study was conducted in two phases, where Phase one was focused on finding out about the attitudes and perceptions of sedentary behavior and the use of mobile applications among prostate cancer survivors using semi-structured interviews. Together with professional experts and a group of men who were diagnosed with prostate cancer, we developed RiseForTx - an application that is used on a smartphone or tablet to reduce time spent in, and to change patterns of, sedentary behaviour each day (Phase two). Part of the intervention was also focused on increasing daily steps to improve physical activity. We tested the intervention to examine (i) how the application works, (ii) if prostate cancer survivors like it and use it; and (iii) if sedentary behaviour and physical activity can reduce the impact of the side effects for treatment and improve quality of life among men on ADT.
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.
The purpose of this study was to evaluate the difference between the optic nerve sheath diameter measured during total intravenous anesthesia and the optic nerve sheath diameter measured during inhalation anesthesia in patients undergoing robot-assisted laparoscopic prostatectomy.
To report the outcome of hypo-fractionated radiotherapy after radical prostatectomy (RP) for prostate cancer (PCa) using IMRT-SIB. 124 patients with PCa at high risk of relapse after RP or diagnosis of biochemical relapse were included. Patients received 62.5 Gy to the prostate bed (PB) and 45 Gy to pelvis nodes in 25 fractions. Androgen suppressive therapy was prescribed based on NCCN risk categories. Median follow-up was 30 months.
