RESUMO
OBJECTIVES: To test the validity of an Internet-based version of Expanded Prostate Cancer Index Composite (EPIC-26) versus the phone-based version. Most men will survive for years after treatment for localized prostate cancer (PCa) and may experience lasting treatment-related toxicities affecting health-related quality of life. The EPIC-26 is a validated instrument that measures health-related quality of life across 5 PCa-specific domains. Previously, EPIC-26 was administered via phone in a large multicenter clinical trial. METHODS: We developed an Internet-based version of EPIC-26. We recruited subjects from two prospective longitudinal study cohorts of PCa patients undergoing local therapy: PROST-QA, and PROSTQA-RP2. Subjects were randomized to either an "Internet-first" or "phone-first" group. Subjects were offered the alternate questionnaire modality 2 weeks after completing the initial modality. RESULTS: 181 subjects were offered enrollment; 133 agreed to participate. 65 subjects were randomized to the "Internet- first" group and 68 subjects to the "phone-first" group. Of these, 37 and 26 subjects respectively completed both questionnaire versions (response rate: 44.4%). Test-retest analysis showed significant intraclass correlations in all 5 domains of EPIC-26: urinary incontinence (râ¯=â¯0.96), urinary irritation (râ¯=â¯0.85), bowel function (râ¯=â¯0.61), sexual function (râ¯=â¯0.94), and hormonal function (râ¯=â¯0.89). There was no effect of order of questionnaire administration. CONCLUSION: This study demonstrates excellent correlation of responses between Internet-based and phone-based EPIC-26 administration. All domains demonstrated test-retest reliability between modalities, without ordering effect. This validates the use of internet-based EPIC-26 in international registries as part of the International Consortium for Health Outcomes Measurement effort, and may facilitate its use in clinical practice and quality improvement.

INTRODUCTION: Hospital-related costs of renal cancer surgery have been described, but the societal costs of surgery-related lost productivity are poorly understood. We estimated the societal cost of renal cancer surgery by assessing surgery-related time off work (TOW) taken by patients and their caretakers. MATERIALS AND METHODS: A total of 413 subjects who underwent partial or radical nephrectomy enrolled in an IRB-approved prospective study received an occupational survey assessing employment status, work physicality, income, surgery-related TOW, and caretaker assistance. We excluded subjects with incomplete occupational information or metastatic disease. We estimated potential wages lost using individual income and TOW, and used logistic regression to evaluate for factors predictive of TOW > 30 days. RESULTS: Of the 219 subjects who responded, 138 were employed at time of surgery. Ninety-seven subjects returned to work, met the inclusion criteria, and were analyzed. Mean age was 54 and 56% of subjects had sedentary jobs. TOW ranged from 7 to 92 days; mean and median TOW was 35 and 33 days, respectively and 58% of subjects took > 30 days off. Mean potential wages lost for TOW was $10,152. Eighty-three percent of subjects had at least one caretaker take TOW (mean/median caretaker TOW: 11/7 days, respectively) to assist in recovery. Subjects with sedentary jobs were less likely to take > 30 days off (OR 0.30; 95% CI 0.09-0.99). CONCLUSIONS: Most renal cancer surgery patients take over 1 month off work. Recognizing the associated societal costs may allow better adjustment of patient expectations, and more comprehensive cost-effectiveness analyses in renal cancer care.

PURPOSE: Harms of prostate cancer treatment on urinary health related quality of life have been thoroughly studied. In this study we evaluated not only the harms but also the potential benefits of prostate cancer treatment in relieving the pretreatment urinary symptom burden. MATERIALS AND METHODS: In American (1,021) and Spanish (539) multicenter prospective cohorts of men with localized prostate cancer we evaluated the effects of radical prostatectomy, external radiotherapy or brachytherapy in relieving pretreatment urinary symptoms and in inducing urinary symptoms de novo, measured by changes in urinary medication use and patient reported urinary bother. RESULTS: Urinary symptom burden improved in 23% and worsened in 28% of subjects after prostate cancer treatment in the American cohort. Urinary medication use rates before treatment and 2 years after treatment were 15% and 6% with radical prostatectomy, 22% and 26% with external radiotherapy, and 19% and 46% with brachytherapy, respectively. Pretreatment urinary medication use (OR 1.4, 95% CI 1.0-2.0, p = 0.04) and pretreatment moderate lower urinary tract symptoms (OR 2.8, 95% CI 2.2-3.6) predicted prostate cancer treatment associated relief of baseline urinary symptom burden. Subjects with pretreatment lower urinary tract symptoms who underwent radical prostatectomy experienced the greatest relief of pretreatment symptoms (OR 4.3, 95% CI 3.0-6.1), despite the development of deleterious de novo urinary incontinence in some men. The magnitude of pretreatment urinary symptom burden and beneficial effect of cancer treatment on those symptoms were verified in the Spanish cohort. CONCLUSIONS: Men with pretreatment lower urinary tract symptoms may experience benefit rather than harm in overall urinary outcome from primary prostate cancer treatment. Practitioners should consider the full spectrum of urinary symptom burden evident before prostate cancer treatment in treatment decisions.
