RESUMEN

INTRODUCTION: Delayed healing of pressure ulcers (PUs) in long-term care facilities (LTCFs) is associated with increased morbidity and expense. OBJECTIVE: The authors hypothesize that guideline-based, weekly coordinated care using specialized wound care surgeon-led bedside teams (SLBTs) may improve PU time-to-heal (TTH) outcomes when compared with usual care (UC). MATERIALS AND METHODS: Using a deidentified United States nationwide database, the authors retrospectively compared TTH outcomes of PUs diagnosed in LTCFs treated by either weekly SLBTs or UC. The SLBTs included an external specialized wound care surgeon (with or without a physician assistant and nurse practitioner) collaborating with facility nurses. Usual care was defined as all patient encounters not known to incorporate this team process. Variables assessed included patient age, gender, and comorbidities. The primary outcome measure was TTH; the TTH outcomes then were compared graphically and statistically between groups. Statistical significance was double-sided P ⟨ .05. RESULTS: In 2014, there were 39 459 consecutive PUs treated by UC and 5985 by SLBTs. The 5985 SLBT wounds originated from 3435 patients in 10 states and all geographic regions (mean age, 76.6 years; 55.9% female; 42.8% with hypertension; 23.7% with diabetes). The mean TTH for wounds managed by SLBTs was 47.5 days (median, 21 days) versus 69.0 days (median, 28 days) for wounds managed by UC, corresponding to an absolute TTH decrease of 21.5 days in wounds managed by SLBTs versus UC. Wounds managed by SLBTs also were significantly more likely to heal in less than 28 days (P ⟨ .0001). CONCLUSIONS: Pressure ulcers managed by coordinated nursing and weekly SLBTs appear to heal significantly faster than wounds managed by UC. Further studies are required to confirm these hypothesis-generating results.

RESUMEN

We report changes in the histopathology of prostate cancer diagnosed in a large urology group practice after the final United States Preventive Services Task Force (USPSTF) Grade D recommendation against prostate-specific antigen screening. All prostate biopsies performed from 2011 through 2015 in a large urology group practice were retrospectively reviewed; 2012 was excluded as a transition year. The changes in biopsy data in years following the USPSTF decision (2013-2015) were then compared with baseline (2011). A total of 10,944 biopsies were evaluated during the study period. Positive biopsy rates rose from 39.1% at baseline to 45.2% in 2015 (P < 0.01) with a marked shift toward more aggressive cancer throughout the study period. The absolute number of patients presenting with Gleason Grade Group 4 or 5 increased from 155/year at baseline to 231, 297, and 285 in 2013, 2014, and 2015, respectively (P < 0.05), unrelated to age or racial changes over time. Black men represented 16% of the cohort. Since the USPSTF recommendation against prostate cancer screening, trends toward a substantial upward grade migration and increased volume of cancers were noted in a cohort of nearly 11,000 patients in a real-world clinical practice. Additionally, continuing reductions in cancer detection in the United States may exacerbate these trends.

RESUMEN

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.

RESUMEN

BACKGROUND: UroVysion fluorescence in situ hybridization (uFISH) was reported to have superior sensitivity to urine cytology. However uFISH studies are limited by varying definitions of what is considered a positive result, absence of histopathology and small sample size. The aim of our study was to better determine the performance characteristics of uFISH and urine cytology by overcoming some of the deficiencies of the current literature. METHODS: Intraoperative bladder wash cytology and uFISH were collected prospectively on all patients. Strict definitions for positivity of uFISH and cytology were determined before initiating the study. A re-review of false-negative uFISH specimens was performed to analyze potential sources of error. Sixteen bladder tumors embedded in paraffin were analyzed by uFISH and compared with the result in the urine. RESULTS: One hundred and twenty-nine specimens were analyzed. Sensitivity was 67% and 69% (p = 0.54); specificity was 72% and 76% (p = 1.0), for uFISH and cytology, respectively. Thirty-two false negative uFISH samples were re-reviewed. Low grade tumors often showed cells with abnormal morphology and patchy DAPI staining but diploid chromosomal counts and a few high grade tumors had tetraploid counts but less than needed to interpret uFISH as positive. uFISH study of the tumors revealed three categories; positive in both tumor and urine (9), negative in both tumor and urine (5) and positive in tumor but negative in urine (2). CONCLUSION: In a pathologically-confirmed analysis of bladder washed urine specimens, uFISH does not outperform urine cytology in cancer detection.

RESUMEN

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.

RESUMEN

AIMS: This study was designed to assess lower urinary tract symptoms (LUTS) following robotic-assisted laparoscopic prostatectomy. METHODS: In a single surgeon series, 938 patients underwent robotic prostatectomy and completed International Prostate Symptom Score surveys at baseline and 6-month follow-up. Patients preoperative LUTS were categorized as mild, moderate, or severe according to the original International Prostate Symptom Score validation. Patient demographics, in addition to clinical and pathologic outcomes were obtained from an Institutional Review Board-approved database. RESULTS: Preoperatively, 55.8% of patients presented with mild, 36.4% with moderate, and 7.8% with severe LUTS. Increased prostate size trended with increased LUTS severity (P < 0.001). Patients who had severe preoperative LUTS witnessed a 57% reduction in International Prostate Symptom Score (from 24.1 to 10.7, P < 0.001). Men with moderate preoperative LUTS also witnessed a significant decrease in postoperative LUTS (from 12.1 to 8.3, P < 0.001). CONCLUSIONS: The majority of patients with moderate or severe LUTS improved significantly following robotic prostatectomy, with the largest improvements seen in the severe group. Prostate cancer patients with severe LUTS should be counseled on the beneficial role of robotic prostatectomy in an effort to improve their voiding dysfunction and as a viable cancer treatment.

RESUMEN

Introducing the topic of comparative effectiveness for prostate cancer treatments with a reminder of the disease's heterogeneity risks tautology. However, the profound variation both in this cancer's biology and its clinical course is increasingly widely recognized, while management alternatives for clinically localized prostate cancer have exploded. Available options now include active surveillance, multiple surgical approaches to prostatectomy, various forms of external-beam and interstitial radiation, and a growing list of energy ablative technologies. Each treatment option has its own efficacy rate as well as its own set of complications, side effects and financial costs. Difficulties comparing these options, together with the high prevalence of the disease, led the Institute of Medicine to include localized prostate cancer among the top 25 priority conditions for future comparative effectiveness research. The sheer volume of possible treatment options, with their individual risks and benefits, can be confusing for patients and clinicians to research, understand and explain. To help clinicians navigate these treatment options, we have assembled this Urologic Oncology Seminar on the comparative effectiveness of treatments for clinically localized prostate cancer. The articles focus on high quality evidence-based medicine and most have included useful tables summarizing seminal trials and available resources.

RESUMEN

Next-generation sequencing (NGS) of the genetic information of cancer cells has revolutionized the field of cancer biology, including prostate cancer (PCa). New recurrent alterations have been identified in PCa (e.g., TMPRSS2-ERG translocation, SPOP and CHD1 mutations, and chromoplexy), and many previous ones in well-established pathways have been validated (e.g., androgen receptor overexpression and mutations; PTEN, RB1, and TP53 loss/mutations). With its highly heterogeneous nature, PCa continues to pose a tremendous challenge in terms of diagnosis and prognosis. Combining the information gained through NGS studies with clinicopathological and radiological data will help diagnose the aggressiveness of the cancer with greater accuracy. Furthermore, understanding the heterogeneity of tumor through single-cell or single-molecule sequencing technology will also strengthen the prognosis and provide better, patient-specific drug identification. As this research becomes more prominent, it is important that urologic oncologists become familiar with the various NGS technologies and the results generated using them. We highlight the commonly used NGS tools and summarize recent discoveries relevant to PCa.

RESUMEN

A 32-year-old patient sustained a penetrating injury to the left flank and kidney after a fall backward onto a glass table. On computed tomography imaging, a 12×10×4 cm glass shard was identified penetrating the renal cortex. The patient was taken to the operating room to remove the foreign object. A rubber-shodded clamp was used to successfully remove the glass shard without complication. Although we commonly encounter stab wounds at our trauma center, the penetrating object is rarely present. The presence of the glass object resulted in a technically challenging and rare case.

RESUMEN

PURPOSE: Several large, randomized, controlled trials provide evidence that neoadjuvant chemotherapy improves the outcome of radical cystectomy for muscle invasive urothelial bladder cancer. We analyzed the designs, methods and observations of these trials to identify patient subgroups that appeared most likely to benefit. We also identified distinguishing features compared to groups that did not achieve improved outcomes. MATERIALS AND METHODS: We analyzed initial and updated methods and results of the 4 main prospective trials of neoadjuvant chemotherapy (SWOG, Medical Research Council, and Nordic I and II) and subsequent meta-analyses. These series are the basis for advocating neoadjuvant chemotherapy in all patients with muscle invasive urothelial bladder cancer who undergo radical cystectomy. RESULTS: The greatest apparent benefit was seen in patients free of cancer at radical cystectomy (pT0). They had markedly improved overall and disease specific survival compared to patients with residual disease. However, improvements occurred regardless of whether there was down-staging from muscle invasive urothelial bladder cancer to pT0 after transurethral resection alone (controls) or after resection plus neoadjuvant chemotherapy. Thus, the major benefit of chemotherapy appeared to be that more patients achieved pT0. We also explored the study limitations that may have influenced outcomes and considered the potential for overtreatment in patients not likely to benefit from chemotherapy. Finally, we used risk stratification to create a decision tree model for selecting patients for neoadjuvant chemotherapy that could conceivably maximize oncologic outcome and minimize overtreatment. CONCLUSIONS: Patients with pT0 in the 4 main neoadjuvant chemotherapy trials and their subsequent meta-analyses experienced similar survival, far exceeding that in groups that did not achieve pT0. The benefit of neoadjuvant chemotherapy appears to be the larger number of cases than in the transurethral resection only group that were down-staged to pT0, suggesting that variables other than chemotherapy may have influenced outcomes. Therefore, strategies to selectively administer neoadjuvant chemotherapy to certain patients at risk have the potential to maintain improved bladder cancer outcomes while reducing overtreatment and its associated toxicity.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

PURPOSE: The Gleason scoring system has been the traditional basis for studies on the assessment and treatment of prostate cancer. Recent reports of long-term prostate cancer outcomes stratified by Gleason score based on the 2005 ISUP (International Society of Urological Pathology) update suggest that important aspects of the biology of prostate cancer correlate with commonly available histopathological information. In this review we present a conceptual framework for the possible existence of distinct but interrelated developmental pathways in the context of the Gleason score in considering various biological and clinical aspects of prostate cancer. This may be useful in characterizing prostate cancer as an indolent condition in some and an aggressive disease in others, in decision making for treatment, and in the interpretation of the biological course and treatment outcomes. MATERIALS AND METHODS: A comprehensive review of clinical, pathological and investigational biological literature on this topic was conducted. In addition, the biological behavior of prostate cancer as interpreted from this survey was compared to that of other solid neoplasms in developing a schema for characterizing the pathogenesis of various forms of the disease. RESULTS: The Gleason scoring system has been found to have fundamental value in predicting the behavior of prostate cancer and assessing outcomes of its treatment. Increasingly, the proportion of Gleason pattern 4 in a prostatectomy specimen is being recognized as a critical factor in predicting the rates of biochemical recurrence and prostate cancer specific mortality. Under the current Gleason classification, a Gleason 3 + 3 = 6 cancer carries a minimal long-term risk of progression or mortality. Risk of biochemical recurrence and prostate cancer specific mortality increases with increasing proportions of the Gleason 4 component in the prostatectomy specimen, from 3 + 3 = 6 with tertiary 4 (ie less than 5% of a 4 component) to 3 + 4 = 7, 4 + 3 = 7 and 4 + 4 = 8. Assuming that the Gleason 4 component increases in volume more rapidly with time than well differentiated components, it can be inferred that a smaller proportion of Gleason 4 could mean that the cancer has been identified at an earlier phase in the natural history of the disease. This could explain the improved prognosis on the basis of length and lead time biases, and conceivably on the basis of a decreased likelihood of cancer cells having metastasized. Correspondingly, increasing amounts of Gleason 4 cancer in a prostate specimen might be explained in 2 ways, as the preferential growth of a single clone of Gleason 4 cells, possibly with intraprostatic spread, or the evolution of Gleason 3 cancer cells to become Gleason 4. These hypotheses have been examined by genetic analysis of metastatic deposits and by comparisons of multiple foci of cancer within individual prostates. The clinical significance of these concepts in regard to disease status at diagnosis, treatment selection, outcomes of treatment, and implications for future research on the basis of clinical and molecular observations are the basis of the developmental schemata we propose. CONCLUSIONS: Given the relatively benign nature of homogeneous, low volume Gleason 3 tumors, and the progressive risk of biochemical recurrence and prostate cancer specific mortality with increasing quantities of Gleason 4 components, we propose that Gleason 4 (and 5) cancers constitute cancer diatheses distinct from that of Gleason 3 cancer. This distinction may contribute to the understanding of the prognosis intrinsic to these biological behavioral patterns, and help guide the translation of findings at molecular and histological levels to a more precise selection of treatments.

RESUMEN

BACKGROUND: The utility of lymph node dissection (LND) during radical nephrectomy for renal cell carcinoma (RCC) continues to be controversial, yet its use by urologists in the United States is unknown. We analyzed the incidence of and trends in LND from a large, nationally representative cancer registry. METHODS: Using the Surveillance, Epidemiology, and End Results registry we identified 37,279 patients with RCC who underwent radical nephrectomy from 1988 to 2005. LND was defined as a surgeon removing ≥5 nodes; however, sensitivity tests were performed using cutoffs of ≥3 and ≥1 nodes. We analyzed changes in LND rates over time and used multivariable logistic regression to predict those who underwent LND. RESULTS: Of the 37,279 patients with RCC, 2,463 (6.6 %) received a LND. There was a gradual decline in LND beginning in 1988 that accelerated after 1997, with the period of 1998-2005 having significantly decreased odds of LND compared with the period 1988-1997 (odds ratio [OR]: 0.65; 95 % confidence interval [95 % CI]: 0.59-0.71). This decline was driven primarily by a 63 % reduction in LND rates among localized tumors (p < .001). CONCLUSIONS: There has been a significant decline in LND rates during radical nephrectomy for localized kidney cancer over the past 7 years. In contrast to prior estimates, very few urologists in the United States are removing ≥5 nodes during lymph node dissection for RCC.

RESUMEN

OBJECTIVE: Given the higher likelihood of extraprostatic extension in high-risk patients, many urologists will sacrifice the neurovascular bundles in such patients in an attempt to decrease the risk of positive surgical margins. In contrast, we frequently perform nerve-sparing in high-risk patients. We analyzed our outcomes in patients with preoperatively high-risk prostate cancer according to the D'Amico risk group classification, and stratified by nerve-sparing status. MATERIALS AND METHODS: An institutional database of 1,503 robotic-assisted laparoscopic prostatectomies (RALP) was queried for patients presenting with PSA > 20 ng/ml, Gleason 8 or higher on biopsy, or clinical stage T2c or higher. Interfascial nerve-sparing was performed whenever oncologically feasible. Validated questionnaires were used to assess baseline and postoperative functional outcomes. RESULTS: Adequate follow-up was available in 123 high-risk patients. Mean serum PSA was 10.8. Bilateral, unilateral, and non-nerve-sparing was performed on 58%, 15%, and 27%, respectively. On final histopathology, 42% were organ confined; 55 patients had extraprostatic extension, and 35 had seminal vesicle invasion. Positive surgical margins occurred in 31%: 15% focal and 16% extensive. Favorable pathologic outcomes (organ-confined and negative surgical margins) were observed in 40%. Biochemical recurrence occurred in 20%. Nerve-sparing was associated with more favorable pathologic features, possibly due to selection bias. When controlling for adverse pathologic features, nerve-sparing was not associated with higher rates of positive surgical margins or biochemical recurrence. At a median follow-up of 13 months, 78% were continent and 56% were potent. The "trifecta" of continence, potency, and freedom from recurrence was achieved in 28 patients (23%). CONCLUSIONS: Nerve-sparing robotic-assisted laparoscopic prostatectomy can be safely performed in patients with preoperatively high risk prostate cancer. Histopathologic and short-term oncologic outcomes at 13-month median follow-up are comparable to those in open surgical series from similar cohorts.

RESUMEN

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 site's $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.
