Monitoring Validated Quality of Life Outcomes After Prostatectomy: Initial Description of Novel Online Questionnaire

OBJECTIVES To describe a novel, low-cost, online health-related quality of life (HRQOL) survey that allows for automated follow-up and convenient access for patients in geographically diverse locations. Clinicians and investigators have been encouraged to use validated HRQOL instruments when reporting outcomes after radical prostatectomy. METHODS The institutional review board approved our protocol and the use of a secure web site (http://www.SurveyMonkey.com) to send patients a collection of validated postprostatectomy HRQOL instruments by electronic mail. To assess compliance with the electronic mail format, a pilot study of cross-sectional surveys was sent to patients who presented for follow-up after robotic-assisted laparoscopic prostatectomy. The response data were transmitted in secure fashion in compliance with the Health Insurance Portability and Accountability Act. RESULTS After providing written informed consent, 514 patients who presented for follow-up after robotic-assisted laparoscopic prostatectomy from March 2010 to February 2011 were sent the online survey. A total of 293 patients (57%) responded, with an average age of 60 years and a median interval from surgery of 12 months. Of the respondents, 75% completed the survey within 4 days of receiving the electronic mail, with a median completion time of 15 minutes. The total survey administration costs were limited to the web sites

Clinicopathological, functional, and immediate oncologic outcome assessment in men aged≤50 years with prostate cancer after robotic prostatectomy.

200 annual fee-for-service. CONCLUSIONS An online survey can be a low-cost, efficient, and confidential modality for assessing validated HRQOL outcomes in patients who undergo treatment of localized prostate cancer. This method could be especially useful for those who cannot return for follow-up because of geographic reasons.

Candidacy for active surveillance may be associated with improved functional outcomes after prostatectomy

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.

Continuing Robotically? The Completion of a Robot-Assisted Radical Prostatectomy After Laparotomy

OBJECTIVE In an effort to curb overtreatment, active surveillance (AS) has grown in popularity as an option for men with low-risk prostate cancer. We evaluated the histopathologic and functional outcomes of patients who qualified for AS, but opted for robotic-assisted laparoscopic prostatectomy (RALP), and compared them to non-AS candidates. METHODS An institutional database of 1,477 RALP performed by a single surgeon was queried for AS candidates, defined as PSA <10 ng/mL, biopsy Gleason score ≤6 with a minimum of 10 biopsy cores, <3 positive cores with <50% tumor volume in a single core and clinical stage ≤T2a. RESULTS Of the 352 patients who would have qualified for AS, 159 (45%) were upgraded: 143 (41%) to Gl 3 + 4, 16 (4.5%) to 4 + 3, zero to Gleason 8 or higher. Seventeen (4.8%) patients were upstaged to pT3. AS candidates were younger and had more favorable tumor characteristics, but similar preoperative functional status. Bilateral nerve sparing was performed on 96% of AS candidates vs. 86% of non-AS candidates (P < 0.001). After 12 months of follow-up in patients who received bilateral nerve sparing, continence was higher in the AS cohort (98% vs. 92%, P < 0.001) but potency was equivalent (87% in each, P = 0.89). On multivariable analysis, candidacy for AS was independently associated with improved continence, but not potency. CONCLUSIONS In addition to having the expected favorable histopathologic features, AS candidates who desire definitive therapy have a high likelihood of achieving excellent functional outcomes, perhaps superior to non-AS candidates, following RALP.

Does size matter? The significance of prostate size on pathologic and functional outcomes in patients undergoing robotic prostatectomy.

The laparoscopic management of difficult adhesions can be quite challenging for even the most experienced of laparoscopic surgeons. We describe a case of managing a suspected enterotomy with a laparotomy during a robot-assisted radical prostatectomy and the surgical options after repair. The case was complicated by a Meckels diverticulum fused and continuous with a urachal cyst, itself a rare occurrence. After the excision of the Meckels diverticulum–urachal complex, the laparotomy incision was closed, and the prostatectomy was performed robotically. We discuss the controversies regarding continuation of a planned robotic procedure after a midline laparotomy.

Unnecessary imaging for the staging of low-risk prostate cancer is common.

Abstract Background: We examined the effect of prostate weight on perioperative data, and the pathological and functional outcomes of robotic-assisted laparoscopic prostatectomy (RALP). Patients and methods: Data were available from 716 consecutive patients before, during and after undergoing RALP at one institution. Prostate size was arbitrarily stratified by recorded prostate weight into <50, 50–80 and >80 g, corresponding to small, moderate and large glands, respectively. Perioperative data and the histopathological and functional outcomes were compared across these groups by both univariable and multivariable-adjusted analyses. Results: Increased prostate size was associated with increased age, preoperative prostate-specific antigen levels, body mass index, operative duration, blood loss, lower biopsy and pathological Gleason scores, and lower pathological staging (P < 0.05). The incidence of extensive positive surgical margins was 14.8%, 9.7%, and 5.3% in small, moderate and large prostates, respectively (P < 0.001). However, after multivariable adjustment, only Gleason score and pathological stage were significantly associated with the incidence of positive margins (P < 0.05); prostate weight was not significantly associated. Overall, 78% and 92% of patients were potent and continent at 12 months, respectively, which was not affected by prostate size. Conclusion: Patients with larger prostates had favourable pathological outcomes after RALP. When controlling for pathological stage, prostate size was not associated with margin positivity. Functionally, neither continence nor potency at 12 months was affected by prostate size.
