Abstract

Nerve-sparing (NS) radical prostatectomy (RP) results in better functional outcomes. Intraoperative neurovascular structure-adjacent frozen section examination (NeuroSAFE) significantly increases the frequency of NS surgery. The effect of NeuroSAFE on postoperative erectile function (EF) and continence is not yet clear.

ICIQ: a brief and robust measure for evaluating the symptoms and impact of urinary incontinence.

Kerry NL Avery, Jenny L Donovan, Tim Peters … (2004)

To develop and evaluate the International Consultation on Incontinence Questionnaire (ICIQ), a new questionnaire to assess urinary incontinence and its impact on quality of life (QoL). A developmental version of the questionnaire was produced following systematic literature review and views of an expert committee and patients. Several studies were undertaken to evaluate the psychometric properties of the questionnaire, including content, construct and convergent validity, reliability and sensitivity to change. The ICIQ was easily completed, with low levels of missing data (mean 1.6%). It was able to discriminate among different groups of individuals, indicating good construct validity. Convergent validity was acceptable, with most items demonstrating 'moderate' to 'strong' agreement with other questionnaires. Reliability was good, with 'moderate' to 'very good' stability in test-retest analysis and a Cronbach's alpha of 0.95. Items identified statistically significant reductions in symptoms from baseline following surgical and conservative treatment. Item reduction techniques were used to determine the final version and scoring scheme, which also demonstrated good psychometric properties. The final ICIQ comprises three scored items and an unscored self-diagnostic item. It allows the assessment of the prevalence, frequency, and perceived cause of urinary incontinence, and its impact on everyday life. The ICIQ is a brief and robust questionnaire that will be of use in outcomes and epidemiological research as well as routine clinical practice. Copyright 2004 Wiley-Liss, Inc.

Development and validation of an abbreviated version of the expanded prostate cancer index composite instrument for measuring health-related quality of life among prostate cancer survivors.

Konrad Szymanski, John Wei, Rodney L Dunn … (2010)

Widespread implementation of health-related quality-of-life (HRQOL) measurement in prostate cancer practice and research requires concise instruments. With 50 questions, the full-length Expanded Prostate Cancer Index Composite (EPIC) is cumbersome to administer outside of studies focusing exclusively on HRQOL. To facilitate HRQOL measurement in a broad range of prostate cancer research and practice settings, we developed and validated an abbreviated version of the EPIC. The 50 questions that constitute the full-length EPIC-50 were evaluated to identify the items suitable for elimination while retaining the ability to measure the 5 prostate cancer-specific HRQOL domains of the EPIC-50. The resulting abbreviated version (EPIC-26) was validated using question responses from 252 subjects who had undergone brachytherapy, external beam radiotherapy, or prostatectomy for prostate cancer. The EPIC-26 internal consistency was measured by Cronbach's α coefficient and reliability using test-retest correlation. Using the high item-scale correlations, clinically relevant content, and preservation of domain psychometrics, 26 items were retained in the EPIC-26 from the 50 questions in the full-length EPIC-50. A high correlation was observed between the EPIC-50 and EPIC-26 versions for the urinary incontinence, urinary irritation/obstruction, bowel, sexual, and vitality/hormonal domain scores (all r ≥ 0.96). The correlations between the different domains were low, confirming that EPIC-26 retained the ability to discern the 5 distinct HRQOL domains. The internal consistency and test-retest reliability for EPIC-26 (Cronbach's α ≥ 0.70 and r ≥ 0.69, respectively for all 5 HRQOL domains) supported its validity. EPIC-26 is a brief, valid, and reliable subjective measure of health quality among patients with prostate cancer and is suitable for measuring the HRQOL among patients undergoing treatment of early-stage prostate cancer.

Anatomical grades of nerve sparing: a risk-stratified approach to neural-hammock sparing during robot-assisted radical prostatectomy (RARP).

Ashutosh K Tewari, Abhishek Srivastava, Michael Huang … (2011)

• To report the potency and oncological outcomes of patients undergoing robot-assisted radical prostatectomy (RARP) using a risk-stratified approach based on layers of periprostatic fascial dissection. • We also describe the surgical technique of complete hammock preservation or nerve sparing grade 1. • This is a retrospective study of 2317 patients who had robotic prostatectomy by a single surgeon at a single institution between January 2005 and June 2010. • Included patients were those with ≥ 1 year of follow-up and who were potent preoperatively, defined as having a sexual health inventory for men (SHIM) questionnaire score of >21; thus, the final number of patients in the study cohort was 1263. • Patients were categorized pre-operatively by a risk-stratified approach into risk grades 1-4, where risk grade 1 patients received nerve-sparing grade 1 or complete hammock preservation and so on for risk grades 2-4, as long as intraoperative findings permitted the planned nerve sparing. • We considered return to sexual function post-operatively by two criteria: i) ability to have successful intercourse (score of ≥ 4 on question 2 of the SHIM) and ii) SHIM >21 or return to baseline sexual function. • There was a significant difference across different NS grades in terms of the percentages of patients who had intercourse and returned to baseline sexual function (P < 0.001), with those that underwent NS grade 1 having the highest rates (90.9% and 81.7%) as compared to NS grades 2 (81.4% and 74.3%), 3 (73.5% and 66.1%), and 4 (62% and 54.5%). • The overall positive surgical margin (PSM) rates for patients with NS grades 1, 2, 3, and 4 were 9.9%, 8.1%, 7.2%, and 8.7%, respectively (P = 0.636). • The extraprostatic extension rates were 11.6%, 14.3%, 29.3%, and 36.2%, respectively (P < 0.001). • Similarly, in patients younger than 60, intercourse and return to baseline sexual function rates were 94.9% and 84.3% for NS grade 1 as compared to 85.5% and 77.2% for NS grades 2, 76.9% and 69% for NS grades 3, and 64.8% and 57.7% for NS Grade 4 (P < 0.001). • The risk-stratified approach and anatomical technique of neural-hammock sparing described in the present manuscript was effective in improving potency outcomes of patients without compromising cancer control. • Patients with greater degrees of NS had higher rates of intercourse and return to baseline sexual function without an increase in PSM rates. © 2011 THE AUTHORS.
