Filter by:There is no randomized controlled trial (RCT) comparing Conformal Radiotherapy (3DCRT) versus the Intensity Modulated Radiotherapy (IMRT) in terms of toxicity and disease control. Data from retrospective studies show that IMRT reduces the risk of severe late complications. More recently, the results from the RTOG 0126 study have also confirmed the benefit from IMRT in reducing acute toxicity for prostate cancer treated with conventional dose escalation. Therefore, to investigate the real clinical benefit of the IMRT over 3DCRT using a hypofractionated schedule in prostate cancer, the investigators developed a RCT.
The purpose of this study is to evaluate the effectiveness of a weight management program for men undergoing a prostatectomy by seeing if the program is easy to follow, impacts weight gain, and reduces risk of cancer recurrence in the participants.
This main purpose of this study is to examine the effects of an exercise intervention to counteract adverse side effects related to Androgen Deprivation Therapy (ADT) in prostate cancer patients. Specifically, a supervised and home-based exercise program will be used to assess its impact on clinical and behavioral variables related to ADT in prostate cancer patients.
Prostate cancer has been the most common neoplastic disease in men in Finland over the last ten years. Prostate-specific antigen (PSA) plays an important role in screening of prostate cancer. However, PSA has a limited sensitivity and specificity for prostate cancer detection. Commonly, the diagnosis of prostate cancer is done by transrectal ultrasonography (TRUS) guided biopsy. Because of the low accuracy of TRUS a systematic biopsy is usually performed instead of targeted TRUS biopsy. As biopsy carries a significant risk of complications, there is an increasing interest in developing more accurate non-invasive imaging modalities. This prospective multi-institutional study will enroll 400 men with clinical suspicion of prostate cancer due to higher serum level of PSA than 2.5 ng/ml and/or abnormal digital rectal examination. Anatomical magnetic resonance imaging (MRI) and diffusion weighted imaging (DWI) at 1.5/3 Tesla (T) magnetic field using surface coils will be used to non-invasively predict the presence or absence of prostate cancer. Targeted TRUS guided biopsy based on MRI findings will be performed in addition to routine twelve core TRUS biopsy. Moreover, selected serum and urine biomarkers as well as biomarkers extracted from fresh biopsy sample will be collected and correlated with the presence or absence of prostate cancer.
The purpose of this study is to collect some parameters which may help to provide guidance on how Androgen Deprivation Therapy (ADT) drugs are renewed and physician satisfaction.
The purpose of this protocol is perform comprehensive immune monitoring studies in patients with castration-resistant prostate cancer receiving Sipuleucel-T in an effort to better understand the mechanism of action of this treatment.
The purpose of this registry is to document the characteristics and management of patients with metastatic castrate resistant prostate cancer (mCRPC) in routine clinical practice, independent of treatment used. Given the rapidly evolving landscape in mCRPC treatments, there is a need for a current and improved understanding of how these treatments fit into the current treatment paradigm for mCRPC, how they are combined and sequenced, and how their relative effectiveness profiles emerge outside of a clinical trial setting. This will be based on documentation and description of sequencing of treatment initiation, termination, and duration; relative effectiveness of treatments; defined medical resource utilization (MRU) and quality-of-life parameters and follow-up for survival.
Background: - People who have cancer might have more medical problems if they smoke. Some studies show that smoking even makes cancer treatment less effective. Researchers want to teach people about how tobacco use affects people after a cancer diagnosis. They want to come up with questions for people who have cancer and who have survived cancer. The questions will be about using cigarettes and other tobacco products and about second-hand smoke. The questions will be used to understand how using tobacco affects people with cancer before, during, and after treatment. This will help doctors plan how to treat people with cancer and create programs to help people quit smoking in the future. Objective: - To evaluate and refine questions that assess tobacco use. Eligibility: - Adults age 21 or older who have cancer or are cancer survivors. The cancer can be at any site and any stage. Design: - This study will take about 1 hour. - Participants will meet one-on-one with an interviewer. They will fill out a questionnaire and talk about the questions. Participants will explain how easy or hard it was to answer the questions and how they decided on their answers. - All participants will be asked the same or very similar questions. Specific questions will be based on the participant s own experiences with tobacco products. - There will be no follow-up activities.
Prostate cancer is currently the leading newly diagnosed cancer in the industrialized world. Treatment of prostate cancer is highly dependent on the stage of the disease. Current methods for staging of bone metastases are known to be inaccurate. Staging of lymph nodes requires surgery associated with risk of bleeding etc. Prior studies from our department suggest that PET/CT is useful in staging of bone metastases in patients with prostate cancer. The aim of this study is to compare the usefulness of Dual time point FDG PET/CT with current methods for the staging of bone and lymph node metastases in patients with newly diagnosed prostate cancer. Better initial staging will result in better treatment of the individual patient. If we are able to develop a more accurate and non-invasive method of staging patients with undetected metastases on current staging will be spared of the side-effects associated with current treatment and staging- impotence, incontinence, radiation damage, bleeding, infection etc.

Current methods for staging are known to be inaccurate. Prior studies from our department suggest that PET/CT is useful in staging of bone metastases in patients with prostate cancer. The aim of this study is to test the usefulness of Choline PET/CT for the staging of bone metastases compared to current standard methods in patients with newly diagnosed prostate cancer. Better initial staging will result in better treatment of the individual patient. If we are able to develop a more accurate method of staging patients with undetected metastases on current staging will be spared of the side-effects associated with current treatment - impotence, incontinence, radiation damage etc.
