Oral conjugated estrogen therapy for treatment of hemorrhagic cystitis.

We report 7 cases of severe hemorrhagic cystitis that required repeated transfusions, surgical intervention and oral conjugated estrogens. Of these 7 cases hematuria resolved completely in 5 during estrogen therapy and decreased sufficiently in 1 to preclude further transfusion. We found conjugated estrogens to be an effective, simple, inexpensive, well tolerated and readily available treatment for hemorrhagic cystitis.

Prostate Cancer Registries: Current Status and Future Directions

CONTEXT Disease-specific registries that enroll a considerable number of patients play a major role in prostate cancer (PCa) research. OBJECTIVE To evaluate available registries, describe their strengths and limitations, and discuss the potential future role of PCa registries in outcomes research. EVIDENCE ACQUISITION We performed a literature review of the Medline, Embase, and Web of Science databases. The search strategy included the terms prostate cancer, outcomes, statistical approaches, population-based cohorts, registries of outcomes, and epidemiological studies, alone or in combination. We limited our search to studies published between January 2005 and January 2015. EVIDENCE SYNTHESIS Several population-based and prospective disease-specific registries are currently available for prostate cancer. Studies performed using these data sources provide important information on incidence and mortality, disease characteristics at presentation, risk factors, trends in utilization of health care services, disparities in access to treatment, quality of care, long-term oncologic and health-related quality of life outcomes, and costs associated with management of the disease. Although data from these registries have some limitations, statistical methods are available that can address certain biases and increase the internal and external validity of such analyses. In the future, improvements in data quality, collection of tissue samples, and the availability of data feedback to health care providers will increase the relevance of studies built on population-based and disease-specific registries. CONCLUSIONS The strengths and limitations of PCa registries should be carefully considered when planning studies using these databases. Although randomized controlled trials still provide the highest level of evidence, large registries play an important and growing role in advancing PCa research and care. PATIENT SUMMARY Several population-based and prospective disease-specific registries for prostate cancer are currently available. Analyses of data from these registries yield information that is clinically relevant for the management of patients with prostate cancer.

Recurrent torsion after previous testicular fixation.

Background: Occasionally patients present with acute testicular pain having undergone a previous testicular fixation for torsion. The aim of this article is to review the literature and determine whether recurrent torsion of the testis is possible and whether the technique used at initial fixation is relevant.

Prostate-specific antigen (PSA) rate of decline post external beam radiotherapy predicts prostate cancer death

BACKGROUND AND PURPOSE To assess the association between PSA velocity (PSAV) in the first 24 months after external beam radiotherapy (EBRT) and prostate cancer-specific mortality (PCSM) and all cause mortality. MATERIALS AND METHODS All eligible patients in the South Australian (SA) Prostate Cancer Clinical Outcomes registry were followed. 848 Patients treated by definitive EBRT with more than one PSA recorded in the two year post-treatment were included. We calculated PSAV by linear regression. RESULTS The mean number of PSA measurements in the 2year period was 4.4 (SD1.9). The median PSAVs across quartiles (Q1-Q4) were -4.17, -1.29, -0.38 and 0.20ng/ml/yr. In multivariable analysis, a U-shaped relationship was seen between PSAV and PCSM with Q1-Q4 hazard ratios (HR) being 3.82 (1.46-10.00), 3.07 (1.10-8.58), 1, 5.15 (1.99-13.30) respectively. HR for all cause mortality in a similar model were 1.79 (1.07-2.98), 1.55 (0.93-2.59), 1.00 and 1.74 (1.04-2.90) for Q1 to Q4 respectively. A rapid PSA decline in the first year was a strong predictor of PCSM. However, in the second year PSA increase was positively associated with PCSM. CONCLUSION A rapid decline in PSA in the first year following EBRT is positively associated with PCSM. This may be a useful early indicator of the need for additional therapies.

Tools for predicting patient-reported outcomes in prostate cancer patients undergoing radical prostatectomy: a systematic review of prognostic accuracy and validity

Background:Radical prostatectomy is a common surgical procedure performed to treat prostate cancer. Patient-reported outcomes after surgery include urinary incontinence, erectile dysfunction, decreased quality of life and psychological effects. Predictive tools to assess the likelihood of an individual experiencing various patient-reported outcomes have been developed to aid decision-making when selecting treatment.Methods:A systematic review was undertaken to identify all papers describing tools for the prediction of patient-reported outcome measures in men with prostate cancer treated with radical prostatectomy. To be eligible for inclusion, papers had to provide a summary measure of accuracy. PubMed and EMBASE were searched from July 2007. Title/abstract screening, and full-text review were undertaken by two reviewers, while data extraction and critical appraisal was performed by a single reviewer.Results:The search strategy identified 3217 potential studies, of which 191 progressed to full-text review and 14 were included. From these studies, 27 tools in total were identified, of which 18 predicted urinary symptoms, six predicted erectile function and one predicted freedom from a group of three outcomes (‘trifecta’) (biochemical recurrence, incontinence and erectile dysfunction). On the basis of tool accuracy (>70%) and external validation, two tools predicting incontinence and two tools predicting erectile dysfunction are ready for implementation.Conclusions:A small number of tools for the prediction of patient-reported outcomes following radical prostatectomy have been developed. Four tools were found to have adequate accuracy and validation and are ready for implementation for the prediction of urinary incontinence and erectile dysfunction.

An appraisal of analytical tools used in predicting clinical outcomes following radiation therapy treatment of men with prostate cancer: a systematic review

BackgroundProstate cancer can be treated with several different modalities, including radiation treatment. Various prognostic tools have been developed to aid decision making by providing estimates of the probability of different outcomes. Such tools have been demonstrated to have better prognostic accuracy than clinical judgment alone.MethodsA systematic review was undertaken to identify papers relating to the prediction of clinical outcomes (biochemical failure, metastasis, survival) in patients with prostate cancer who received radiation treatment, with the particular aim of identifying whether published tools are adequately developed, validated, and provide accurate predictions. PubMed and EMBASE were searched from July 2007. Title and abstract screening, full text review, and critical appraisal were conducted by two reviewers. A review protocol was published in advance of commencing literature searches.ResultsThe search strategy resulted in 165 potential articles, of which 72 were selected for full text review and 47 ultimately included. These papers described 66 models which were newly developed and 31 which were external validations of already published predictive tools. The included studies represented a total of 60,457 patients, recruited between 1984 and 2009. Sixty five percent of models were not externally validated, 57% did not report accuracy and 31% included variables which are not readily accessible in existing datasets. Most models (72, 74%) related to external beam radiation therapy with the remainder relating to brachytherapy (alone or in combination with external beam radiation therapy).ConclusionsA large number of prognostic models (97) have been described in the recent literature, representing a rapid increase since previous reviews (17 papers, 1966–2007). Most models described were not validated and a third utilised variables which are not readily accessible in existing data collections. Where validation had occurred, it was often limited to data taken from single institutes in the US. While validated and accurate models are available to predict prostate cancer specific mortality following external beam radiation therapy, there is a scarcity of such tools relating to brachytherapy. This review provides an accessible catalogue of predictive tools for current use and which should be prioritised for future validation.

Development of Indicators to Assess Quality of Care for Prostate Cancer

BACKGROUND The development, monitoring, and reporting of indicator measures that describe standard of care provide the gold standard for assessing quality of care and patient outcomes. Although indicator measures have been reported, little evidence of their use in measuring and benchmarking performance is available. A standard set, defining numerator, denominator, and risk adjustments, will enable global benchmarking of quality of care. OBJECTIVE To develop a set of indicators to enable assessment and reporting of quality of care for men with localised prostate cancer (PCa). DESIGN, SETTING, AND PARTICIPANTS Candidate indicators were identified from the literature. An international panel was invited to participate in a modified Delphi process. Teleconferences were held before and after each voting round to provide instruction and to review results. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Panellists were asked to rate each proposed indicator on a Likert scale of 1-9 in a two-round iterative process. Calculations required to report on the endorsed indicators were evaluated and modified to reflect the data capture of the Prostate Cancer Outcomes Registry-Australia and New Zealand (PCOR-ANZ). RESULTS AND LIMITATIONS A total of 97 candidate indicators were identified, of which 12 were endorsed. The set includes indicators covering pre-, intra-, and post-treatment of PCa care, within the limits of the data captured by PCOR-ANZ. CONCLUSIONS The 12 endorsed quality measures enable international benchmarking on the quality of care of men with localised PCa. Reporting on these indicators enhances safety and efficacy of treatment, reduces variation in care, and can improve patient outcomes. PATIENT SUMMARY PCa has the highest incidence of all cancers in men. Early diagnosis and relatively high survival rates mean issues of quality of care and best possible health outcomes for patients are important. This paper identifies 12 important measurable quality indicators in PCa care.
