Longitudinal Assessment of Health-Related Quality of Life in Men With Localized Prostate Cancer
The purpose of this study is to assess quality-of-life of men with prostate cancer. "Quality-of-life" means how you feel about your life as a result of your disease and its treatment. We hope that this questionnaire will help show how prostate cancer treatments affect quality-of-life. It will help doctors and future patients to make better treatment choices. Some men may wish to have a more demanding treatment with a higher risk of harmful effects. Others may prefer a treatment that will have the smallest effect on their quality-of-life.
This questionnaire will help us measure these effects and decide which is the best treatment for a given patient.
The intent of the protocol is to assess health-related quality-of-life (HRQOL) in men treated for localized prostate cancer with 1 of 6 established management alternatives: external (XRT)or interstitial radiotherapy (IRT), open radical prostatectomy (RP), laparoscopic radical prostatectomy (LRP), combined radiotherapy and brachytherapy (Combined RT) or watchful waiting (WW). HRQOL is an important aspect of any treatment for prostate cancer due to the beliefs by many that cancer control rates are similar across common modalities and HRQOL reduction from treatment is substantial (1-5). Therefore, HRQOL appears to occupy a central role in the decision making process related to treatment selection.

Medical and Biotech [MESH] Definitions
Predetermined sets of questions used to collect data - clinical data, social status, occupational group, etc. The term is often applied to a self-completed survey instrument.
Systematic gathering of data for a particular purpose from various sources, including questionnaires, interviews, observation, existing records, and electronic devices. The process is usually preliminary to statistical analysis of the data.
Information application based on a variety of coding methods to minimize the amount of data to be stored, retrieved, or transmitted. Data compression can be applied to various forms of data, such as images and signals. It is used to reduce costs and increase efficiency in the maintenance of large volumes of data.
Any deviation of results or inferences from the truth, or processes leading to such deviation. Bias can result from several sources: one-sided or systematic variations in measurement from the true value (systematic error); flaws in study design; deviation of inferences, interpretations, or analyses based on flawed data or data collection; etc. There is no sense of prejudice or subjectivity implied in the assessment of bias under these conditions.
A field of biology concerned with the development of techniques for the collection and manipulation of biological data, and the use of such data to make biological discoveries or predictions.
