The study is to examine a moderate hypofractionation regimen of proton beam therapy for high risk or unfavorable intermediate risk prostate cancer. The prostate and seminal vesicles are treated with 6750 centigray (RBE) in 25 fractions (i.e. 270 centigray/fraction), while the regional pelvic nodes receive 4500 centigray (RBE) in 25 fractions (i.e. 180 centigray/fraction) simultaneously. The overall treatment time is 5 weeks.
30-40% of patients who undergo radical prostatetecomy (RP) with curative intent for their localized prostate cancer experience relapse of their disease. Thus, improved therapeutic approaches are needed in this patient population. Enhancing the patient's anti-tumor immune response prior to surgery may improve long-term outcomes following RP.
The benefit of dose escalation in radiotherapy (RT) for biochemical control of prostate cancer is a clearly established fact based on the results of different published prospective trials. This benefit, acquired with three-dimensional conformal radiation technique is counterbalanced by an increase in urinary and gastrointestinal toxicity. The joint progress of dose planning systems and multileaf collimators (MLC) technology have enabled the Intensity Modulated Radiation Therapy (IMRT). Recently the contribution of "spacers" positioned in the septum between the rectum and the prostate could improve the functional results of IMRT in terms of rectal toxicity. The aim of the investigators study is to assess the dosimetric gain from the contribution of the implantable BioProtect balloon on organs at risk.
This study evaluates the dose received by the prostate with in vivo dosimetry when delivering image guided radiation therapy (IGRT) associated with intensity modulated radiation therapy (IMRT) for patients with localized prostate cancer using two repositioning techniques: fiduciary markers or soft tissues.
The purpose of this study is to evaluate the effectiveness of the two most established primary treatments for patients with clinically localized prostate cancer: radical retropubic prostatectomy, and external-beam radiotherapy. The primary aim is assessing biochemical disease-free survival, overall survival, and prostate cancer-specific survival. As secondary objectives quality of Life impact of treatments' side effects will be also assessed.
Mild cognitive impairment (MCI) with ageing is thought in part to be related to reduced serum sex hormones which is well-recognized, especially in females, but poorly understood. International studies assessing hormone replacement therapy (HRT) to prevent/reduce MCI are ongoing. MCI leads to morbidity, reduced quality of life and substantial healthcare costs. The commonest therapeutically induced reduction in sex hormone level in men is treatment of prostate cancer (PCa). PCa is androgen dependent and androgen deprivation therapy (ADT) suppressing testosterone to castrate levels is key therapy for advanced disease. About one million men worldwide have received ADT for PCa, mostly using luteinising hormone releasing hormone agonists (LHRHa) although oral oestrogens were used in the past; eventually perhaps 4% of Caucasians may be castrated. MCI as a side effect of castration in men remains poorly researched. This study aims to demonstrate that pathological changes occur in the brains of a significant proportion of prostate cancer patients subjected to ADT that correlate with MCI symptoms. Highlighting the pathological changes of MCI should improve understanding and interventions for slowing/preventing MCI in PCa survivors. Brain scans employing positron emission tomography (PET) imaging technique will be used to detect the presence of pathological changes in the brain that relate to ADT induced MCI. MCI will be assessed by neuropsychological assessments (standard paper-based questionnaires and online) and its neural basis will be investigated using magnetic resonance imaging (MRI).
The purpose of our study is to image human prostate tissue using a transrectal photoacoustic imaging probe.
1. The investigators hypothesize that increasing radiation dose to the functional MRI-defined lesion in the prostate bed will result in an improved initial complete response (reduction in prostate-specific antigen (PSA) to < 0.1 ng/mL), which is related to long-term outcome biochemically. 2. Biomarker expression levels differ in the DCE-MRI enhancing and non-enhancing tumor regions. 3. 10-15% of men undergoing RT have free circulating DNA (fcDNA) or tumor cells (CTC) that are related to an adverse treatment outcome. 4. Prostate cancer-related anxiety will be reduced in the MRI targeted SRT arm, because the patients will be aware that the dominant tumor will be targeted with higher radiation dose.
To evaluate the clinical impact of an online video simulator during the learning period of laparoscopic radical prostatectomy.
The purpose of this study is to assess the safety and effectiveness of natural killer (NK) cell and natural killer T (NKT) cell-based autologous adoptive immunotherapy in subjects with metastatic, treatment-refractory breast cancer, glioma, hepatocellular carcinoma, squamous cell lung cancer, pancreatic cancer, colon cancer or prostate cancer.
