RESUMO
PURPOSE: Previously we reported the development of a novel, inexpensive, online method to collect health related quality of life information to facilitate responses among patients and decrease loss to followup. We validated the practice by comparing responses to the SHIM (Sexual Health Inventory for Men), a representative validated instrument, when administered on line and in the traditional paper form. MATERIALS AND METHODS: Consented patients were administered validated health related quality of life instruments, including the SHIM, in office and via e-mail. Responses to the SHIM were compared between the administration formats. Paired sample testing was done to analyze test-retest reliability, concordance was assessed by intraclass analysis and a Bland-Altman plot, and the Cronbach α was used to examine internal reliability. Criterion validity was measured using SHIM defined erectile function categories and a dichotomized potency definition (SHIM 17 or greater). RESULTS: Of the 508 men who consented to participate 359 (71%) completed the SHIM in person, 277 (55%) completed the online form (p <0.001) and 116 (23%) contemporaneously completed each instrument. Comparison of scores revealed little variation and strong correlation (r(2) = 0.83, p <0.001). Intraclass and Bland-Altman analysis revealed strong agreement between the media. The Cronbach α was excellent (0.97) for the online tool. Erectile function classification was identical in 73% of patients with only 7% differing by more than 1 class. Dichotomized potency was consistently defined in 94% of patients. CONCLUSIONS: The online administered SHIM maintains validity and provides consistent responses. Online administration can capture patients who do not complete paper questionnaires and may serve as a reliable adjunct to paper administration for validated outcomes research.

PURPOSE: Physician knowledge of factors related to patient decisional regret following definitive management for localized prostate cancer is an important but under evaluated element in comprehensive patient counseling. Using validated instruments, we analyzed the relationships of pathological, perioperative and functional health related quality of life variables to treatment related regret following robot-assisted laparoscopic prostatectomy. MATERIALS AND METHODS: Of 953 consecutive patients presenting for followup after robot-assisted laparoscopic prostatectomy 703 (74%) completed validated measures of health related quality of life and treatment decisional regret. Baseline functional measures were assessed with the Sexual Health Inventory for Men and International Prostate Symptom Score. Questionnaires were administered a median of 11.1 months (IQR 4.6-26.1) after surgery. Clinicopathological, perioperative and functional outcomes were analyzed with univariable and multivariable models to examine associations with patient decisional regret. RESULTS: Of the patients 88% did not regret the decision to undergo robot-assisted laparoscopic prostatectomy. Baseline health related quality of life, specifically baseline incontinence and superior erectile function, independently predicted increased postoperative decisional regret. In addition, older age, postoperative incontinence measured by pad use, postoperative erectile dysfunction and longer time from surgery were independent predictors of increased decisional regret. Preoperative cancer risk, and histopathological and short-term biochemical outcomes were unrelated to decisional regret. CONCLUSIONS: Decisional regret following robot-assisted laparoscopic prostatectomy is independently predicted by age, baseline urinary and erectile function, perioperative outcomes, and postoperative urinary and erectile function. These results may be useful to urologists during preoperative patient counseling to set realistic expectations for the postoperative course, potentially improving the surgical experience.

BACKGROUND: To define the pathologic and functional outcomes of men 50 years of age and younger with prostate cancer in a contemporary robotic cohort, this study was designed. METHODS: Patients undergoing robotic-assisted laparoscopic prostatectomy from April 2002 to April 2012 (n = 2,495) formed the base population for the current analyses. The patients were dichotomized according to their age≤50 (n = 271) and>50-year-old (n = 2,224). Clinicopathological and health-related quality-of-life outcomes were recorded and analyzed for differences. Propensity score matching was used when assessing urinary and sexual function outcome. RESULTS: Baseline prostate-specific antigen and clinical stage were similar between men older than 50 years and those younger. Younger patients had less severe disease (D׳Amico risk and Gleason scores) and smaller prostates. Young men had higher rates of erectile function at all time points, including baseline (94% vs. 83% at 12mo, P <0.01). Continence was similar at all time points except for 6 months, where younger patients experienced a faster return than older patients and then remained constant, while older patients continued to improve (96% vs. 89%, P<0.01). After matching process, the difference in erectile function at 6-month follow-up was lost. CONCLUSION: Most men aged 50 years and younger who received robotic-assisted laparoscopic prostatectomy had clinically significant prostate cancer. Although histopathologic and short-term oncologic outcomes were nearly identical when compared to older patients, younger men had a more rapid and superior return of erectile function.

AIM: The aim of this study was to clarify and examine the outcomes of prostate cancer patients classified as intermediate risk (IR) using the D'Amico risk classification system, specifically focusing on the influence of primary and secondary biopsy Gleason score (BGS). PATIENTS AND METHODS: An institutional review board-approved database of robotic-assisted radical prostatectomies performed after 2006 was stratified by standard D'Amico criteria. IR patients were then sub-stratified by BGS. Pathologic and intermediate-term biochemical disease-free survival (BDFS) outcomes were analyzed. RESULTS: Overall, 1,090 patients were classified as D'Amico low-risk, 896 as IR, and 240 as high-risk. Of the 896 IR patients, 63 had BGS 6, 630 were 3 + 4 = 7, and 203 4 + 3 = 7. Among IR patients, as the BGS increased, there was an increasing likelihood of extracapsular extension (21, 28, and 38%, respectively; p = 0.005), positive surgical margins (14, 26, 31%; p = 0.048), and worse 3-year BDFS (96, 94, 88%; p = 0.01). Multivariable logistic regression and Cox regression analyses confirmed differences among IR groups. CONCLUSION: D'Amico IR patients demonstrate significant heterogeneity in both pathologic outcomes and BDFS. IR patients with a BGS of 6 appear to have similar intermediate-term BDFS as low-risk patients. An increasing BGS from 3 + 3 to 3 + 4 to 4 + 3 results in a higher likelihood of locally-advanced disease and intermediate-term biochemical failure.

OBJECTIVE: To investigate whether tumours at threshold values for detection on magnetic resonance imaging (MRI) represent clinically significant tumours or not, and therefore the utility of MRI in active surveillance (AS) protocols. PATIENTS AND METHODS: A retrospective analysis of a single institution database was performed after Institutional Review Board approval. Between 2010 and 2013, 1633 patients underwent robot-assisted laparoscopic prostatectomy (RALP) at a single institution by a single surgeon. Of these, 1361 had complete clinical data and were included in analysis. Multivariate logistic regression was used to assess histopathological grade compared to tumour size whilst controlling for biopsy Gleason score, prostate-specific antigen level, body mass index, race, and age. RESULTS: Of 120 tumours <5 mm in size, four were Gleason score 4 + 3. Of 276 tumours of 5-10 mm, 22 (8.1%) were Gleason score 4 + 3 and one (0.2%) was Gleason score 8. On multivariate regression analyses, tumours of <5 mm were much less likely to be high grade (Gleason score >3 + 4) at RALP compared to larger tumours (3.3% vs 25.1%, P < 0.001), or Gleason score ⩾8 (0.0% vs 7.6%, P < 0.001). Size was further shown to significantly correlate with grade on multivariate regression (P < 0.001). CONCLUSIONS: Prostate tumours below the detection threshold for MRI (5 mm) most probably represent clinically insignificant tumours, which alone would not necessitate leaving AS in favour of more aggressive therapy. These findings point to a possible role of MRI in modern AS protocols.
RESUMO
PURPOSE: The natural history and optimal management strategy for men with human immunodeficiency virus (HIV) and prostate cancer remain to be definitively characterized. This study was conducted to evaluate the clinical characteristics and outcomes of HIV-seropositive men treated with robotic-assisted radical laparoscopic prostatectomy for localized prostate cancer. METHODS: After Institutional Review Board approval, a prospective database of 2175 operative cases of clinically localized prostate adenocarcinoma was reviewed. Thirteen patients were identified as HIV-positive. Tumor characteristics, operative outcomes, postoperative outcomes, histology (Gleason score), local invasion, biochemical recurrence, and surgical complications were compared with HIV-negative patients. RESULTS: There were no preoperative demographic differences between the HIV-positive and HIV-negative patients. HIV-positive patients had higher prostate specific antigen (PSA) levels at time of diagnosis which was not statistically significant. However, HIV-positive patients had higher D'Amico risk assessment (p < 0.05). There was no postoperative complication. HIV-positive patients treated with robotic prostatectomy had similarly favorable perioperative and short-term biochemical recurrence-free survival outcomes. CONCLUSION: Our findings show that minimally invasive prostatectomy can be safely considered as a therapeutic option in otherwise eligible HIV-positive patients with clinically significant prostate cancer. Further research is necessary to outline a diagnostic and treatment guideline for HIV-positive men in detection and treatment of prostate cancer.

OBJECTIVES: Metabolic syndrome (MetS), the constellation of obesity and related risk factors for cardiovascular disease, is an expanding epidemiologic concern in the United States and the developed world. However, the relationship between MetS and prostate cancer remains to be definitively assessed. We evaluated the association between obesity and MetS with prostate cancer pathology and surgical and functional outcomes. MATERIALS AND METHODS: A total of 2,639 patients underwent robotic-assisted laparoscopic prostatectomy (RALP) for localized prostate cancer between March 2003 and July 2012. Of them, 186 patients met the criteria for MetS as defined by the presence of obesity (body mass index [BMI] ≥ 30 kg/m(2)) in conjunction with 2 or more of the following: hypertension (HTN), dyslipidemia (D), and diabetes (DM). Additionally, reference cohorts of (1) 663 nonobese men without HTN, D, or DM; (2) 184 obese patients without HTN, D, or DM; and (3) 211 obese men with solitary risk factors were identified for comparison. Demographic, histopathologic, and perioperative clinical parameters were compared. RESULTS: In comparison with patients without MetS, patients with MetS had larger prostates (Odds Ratio (OR) = 1.609, 95% Confidence Interval (CI) = 1.04-2.49, P = 0.03), increased blood loss (OR = 1.592, 95% CI = 1.15-2.21, P = 0.01), and surgical complexity (OR = 4.940, 95% CI = 2.29-10.69, P<0.001). There was no statistical difference observed between these groups in regard to complication rates, pathologic grade, stage, and postoperative continence or erectile function. With the exception of larger prostates found among men with MetS, men with obesity alone and obesity with 1 additional risk factor appeared similar to those with MetS. CONCLUSIONS: Patients with MetS had similar perioperative, histopathologic, and functional outcomes compared with reference cohorts undergoing RALP. RALP is safe, feasible, and efficacious in men with MetS.

We conducted a retrospective chart review of robotic prostatectomies done by a single surgeon between 2003 and 2012. During that time period, we identified two patients within the year 2012, with ileal pouch-anal anastomosis (IPPA) who also underwent robotic prostatectomies. The demographics and postoperative characteristics of the two patients were assessed. In both patients, prostatectomy, bilateral nerve sparing, and pelvic lymphadenectomy were successfully performed and the integrity of ileal pouch was maintained. There was a mean surgical time of 144.5 minutes, and an average estimated blood loss was 125 mL. Both patients were discharged on the second day postoperatively. In both patients there was a Gleason upgrade to 3 + 4, with negative margins, and preservation of fecal and urinary continence by their six-month followup. Owing to surgical modifications, these two surgeries represent the first successful robotic prostatectomies in patients with a J-pouch.
RESUMO
OBJECTIVES: Longitudinal studies report racial disparities in prostate cancer (PCa) including greater incidence, more aggressive tumor biology, and increased cancer-specific mortality in African American (AA) men. Regret concerning primary treatment selection is underevaluated in patients with PCa. We investigated the relationships between clinicopathologic variables across racial and socioeconomic lines following robotic-assisted laparoscopic prostatectomy. MATERIALS AND METHODS: We assessed treatment decisional regret using a validated questionnaire in a total of 484 white and 72 AA patients with PCa who were followed up for a median of 16.6 months post-robotic-assisted laparoscopic prostatectomy. Socioeconomic status (SES) information was aggregated from 2010 US census zip code data. Perioperative clinicopathologic characteristics and functional outcomes were compared between groups. Univariate and multivariate regression analyses were used to evaluate the influence of race, aggregate SES, and other clinical and demographic characteristics on decisional regret. RESULTS: The majority (87.7%) of the population was not regretful of their decision to undergo treatment. However, a greater proportion of AA vs. white patients were regretful (20.6% vs. 11.2%, respectively; P = 0.03). AA and white men were similar on all functional, clinical, and pathologic features with the exception of younger age among AA men (56 vs. 60 y, respectively; P<0.001). Although there were significant differences in SES by race (P<0.001), regret did not differ by SES (ß =-1.53; P = 0.15). Race, postoperative sexual dysfunction, pad usage, and length of hospital stay, however, were significantly associated with decisional regret. CONCLUSIONS: AA men were more regretful than white men, after adjusting for clinicopathologic characteristics and postoperative functional outcomes.

Previous abdominal or prostate surgery can be a significant barrier to subsequent minimally invasive procedures, including radical prostatectomy (RP). This is relevant to a quarter of prostatectomy patients who have had previous surgery. The technological advances of robot-assisted laparoscopic RP (RALP) can mitigate some of these challenges. To that end, our objective was to elucidate the effect of previous surgery on RALP, and to describe a multidisciplinary approach to the previously entered abdomen. One-thousand four-hundred and fourteen RALP patients were identified from a single-surgeon database. Potentially difficult cases were discussed preoperatively and treated in a multidisciplinary fashion with a general surgeon. Operative, pathological, and functional outcomes were analyzed after stratification by previous surgical history. Four-hundred and twenty (30 %) patients underwent previous surgery at least once. Perioperative outcomes were similar among most groups. Previous major abdominal surgery was associated with increased operative time (147 vs. 119 min, p < 0.001), as was the presence of adhesions (120 vs. 154 min, p < 0.001). Incidence of complications was comparable, irrespective of surgical history. Major complications included two enterotomies diagnosed intraoperatively and one patient requiring reoperation. All cases were performed robotically, without conversion to open-RP. There was no difference in biochemical disease-free survival among surgical groups and continence and potency were equivalent between groups. In conclusion, previous abdominal surgery did not affect the safety or feasibility of RALP, with all patients experiencing comparable perioperative, functional, and oncologic outcomes.
