简要总结
RATIONALE: Quality of life assessment in patients undergoing prostate cancer treatment may help determine the intermediate and long-term effects of the treatment on these patients.
PURPOSE: Clinical trial to study the effectiveness of two questionnaires in assessing quality of life of patients who have prostate cancer.
详细描述
OBJECTIVES:
- Assess the scale structure, psychometric validity, and reliability of quality of life measurements using the EORTC QLQ-C30 and the prostate cancer-specific QLQ-PR25 questionnaires in patients with stage I-IV prostate cancer.
OUTLINE: This is a multicenter study. Patients are stratified according to stage of disease (local or locally advanced disease vs metastatic disease).
Patients complete EORTC QLQ-C30 and prostate cancer-specific QLQ-PR25 questionnaires before therapy and at 3 months after the start of therapy. Patients in stratum II also complete questionnaires at 6 months after the start of therapy.
PROJECTED ACCRUAL: A total of 375 patients will be accrued for this study.

结局指标
主要结局
psychometric validity of the PR25 module
时间窗: before start of treatment, three months after the start of primary treatment and six months after the start of primary treatment.
Quality of life scores will be evaluated for psychometric validity by: * Scale structure using multi-trait scaling analysis * Reliability using tests of internal consistency * Test-retest reliability * Validity using inter-scale correlations and known group comparisons * Sensitivity to change using two measurements of Quality of Life and ANOVA to look for the significance of changes in quality of life scores as a function of observed changes in clinical status over time.
次要结局
- debriefing questionnaire information(at baseline)
