Translation and validation of the Portuguese version of the International Consultation on Incontinence Questionnaire (ICIQ) Bladder Diary.

INTRODUCTION AND HYPOTHESIS: The International Consultation on Incontinence Questionnaire (ICIQ) Bladder Diary (BD) is a standardized and validated diary, developed in the English language, designed to assess lower urinary tract symptoms (LUTS) in men and women. This study reports the translation, cross-cultural adaptation and validation process of this diary to the Portuguese language. METHODS: After translation and back-translation of the ICIQ-BD to Portuguese, 140 urologic patients were asked to fill in this 3-day diary as well as the Overactive Bladder questionnaire Short Form (OABqSF) and a questionnaire evaluating the difficulties in filling out the ICIQ-BD. A subset of 60 patients filled out a second diary with/without LUTS treatment in between (30 patients in each group). In addition, content validity, internal consistency, criterion and construct validity were tested. RESULTS: The Portuguese version of the ICIQ-BD showed adequate internal consistency (Cronbach's alpha of 0.78), and patients reported few difficulties in filling out this tool, answering most commonly 1 on a 1-6 scale of difficulty. Excellent test-retest reliability and responsiveness of the diary were observed when comparing the first diary to a second completed 2-6 weeks later. Criterion validity was also confirmed, given the good correlation with the OABqSF (Pearson's 0.386-0.447). Finally, construct validity was established through statistically significant concordance between data obtained in the BD with generally accepted theories. CONCLUSION: The present version of the ICIQ-BD is the first bladder diary successfully validated in the Portuguese language. It is a suitable and standardized tool for scientific research and diagnostic assessment of LUTS in adult men and women.

Prostate Ewing Sarcoma/PNET: A case of long survival in a highly aggressive malignancy.

Prostate Ewing sarcoma/peripheral primitive neuroectodermal tumor (ES/PNET) is extremely rare. Currently, a multimodal approach is recommended, although there is no standard treatment. Nevertheless, this tumor has a very poor prognosis, with the longest reported survival of 24 months. We present a case of locally advanced prostate ES/PNET in a 29-year-old male who was treated with a multimodal approach. The patient is alive and disease free, with a seven year follow-up, with very good quality of life. This exceptionally long survival may be the result of the very aggressive multimodal treatment chosen and described herein.

Circulating tumor cell detection methods in renal cell carcinoma: A systematic review.

Circulating tumor cells (CTCs) have a potential role as the missing renal cell carcinoma (RCC) biomarker. However, the available evidence is limited, and detection methods lack standardization, hindering clinical use. We performed a systematic review on CTC enrichment and detection methods, and its role as a biomarker in RCC. Full-text screening identified 54 studies. Reviewed studies showed wide heterogeneity, low evidence level, and high risk of bias. Various CTC detection platforms and molecular markers have been used, but none has proven to be superior. CTC detection and CTC count seem to correlate with staging and survival outcomes, although evidence is inconsistent. CTC research is still in an exploratory phase, particularly in RCC. Further studies are still necessary to achieve a standardization of techniques, molecular markers, CTC definitions, and terminology. This is essential to ascertain the role of CTCs as a biomarker and guide future liquid biopsy research in RCC.
