Comparison of Digital Rectal Examination and Serum Prostate Specific Antigen in the Early Detection of Prostate Cancer: Results of a Multicenter Clinical Trial of 6,630 Men.

To compare the efficacy of digital rectal examination and serum prostate specific antigen (PSA) in the early detection of prostate cancer, we conducted a prospective clinical trial at 6 university centers of 6,630 male volunteers 50 years old or older who underwent PSA determination (Hybritech Tandom-E or Tandem-R assays) and digital rectal examination. Quadrant biopsies were performed if the PSA level was greater than 4 µg./l. or digital rectal examination was suspicious, even if transrectal ultrasonography revealed no areas suspicious for cancer. The results showed that 15% of the men had a PSA level of greater than 4 µg./l., 15% had a suspicious digital rectal examination and 26% had suspicious findings on either or both tests. Of 1,167 biopsies performed cancer was detected in 264. PSA detected significantly more tumors (82%, 216 of 264 cancers) than digital rectal examination (55%, 146 of 264, p = 0.001). The cancer detection rate was 3.2% for digital rectal examination, 4.6% for PSA and 5.8% for the 2 methods combined. Positive predictive value was 32% for PSA and 21% for digital rectal examination. Of 160 patients who underwent radical prostatectomy and pathological staging 114 (71%) had organ confined cancer: PSA detected 85 (75%) and digital rectal examination detected 64 (56%, p = 0.003). Use of the 2 methods in combination increased detection of organ confined disease by 78% (50 of 64 cases) over digital rectal examination alone. If the performance of a biopsy would have required suspicious transrectal ultrasonography findings, nearly 40% of the tumors would have been missed. We conclude that the use of PSA in conjunction with digital rectal examination enhances early prostate cancer detection. Prostatic biopsy should be considered if either the PSA level is greater than 4 µg./l. or digital rectal examination is suspicious for cancer, even in the absence of abnormal transrectal ultrasonography findings.

Comparative Effectiveness of a Patient Centered Pathology Report for Bladder Cancer Care.

PURPOSE: Patients have unprecedented access to their medical records. However, many documents, such as pathology reports, may be beyond the health literacy of most patients. We compared the effectiveness of bladder biopsy patient centered pathology reports with standard reports. MATERIALS AND METHODS: Local bladder cancer experts reached consensus on the important elements of a bladder biopsy pathology report to inform prognosis and counseling. Patient focus groups identified the patient centered formats and language to convey these elements and constructed a pilot patient centered pathology report. A total of 40 patients undergoing bladder biopsy were block randomized to receive the standard report with or without the patient centered report. We assessed patient self-efficacy, and provider communication and empathy, and tested bladder cancer knowledge at pathology disclosure and 1 month later. We compared study groups with descriptive statistics. RESULTS: Experts identified stage, grade and histology as the most important elements of a bladder biopsy pathology report. Patients prioritized 3 themes, including narrative format, tumor stage illustration and risk stratification for recurrence. A total of 39 patients completed initial and followup assessments. Patients with the patient centered pathology report had improved ability to identify cancer stage compared to those with the standard report. Initially 58% of patients with the standard report vs 20% with the patient centered report were unable to describe stage but at followup this incidence was 47% vs 15% (p = 0.02 and 0.03, respectively). Those with the patient centered report also trended toward improved identification of cancer grade. Provider communication trended toward improvement for the patient centered report. Ratings of patient self-efficacy did not differ by report. CONCLUSIONS: Patient centered pathology reports are associated with greater patient knowledge about the bladder cancer diagnosis. The reports may aid patient-provider communication. This pilot study may serve as a model for the development of patient centered pathology reports for other cancers.

ERG overexpression and PTEN status predict capsular penetration in prostate carcinoma.

BACKGROUND: This study examines the combined effect of two common genetic alterations, ERG and PTEN, in prostate carcinoma progression. METHODS: Prostate tissue from 90 patients having unilateral capsular penetrating lesions, and a contra-lateral organ confined second lesion, were examined by immunohistochemistry for the expression of the TMPRSS2:ERG transformation product ERG and the loss of expression of PTEN, a powerful phosphatase inhibiting the PI3 kinase pathway. Multivariate logistic regression was carried out to analyze the data. RESULTS: After adjusting for Gleason score, the odds of having capsular penetration were 5.19 times higher (P = 0.015) for ERG+/PTEN- group as compared to the wild type (ERG-/PTEN+). CONCLUSIONS: This study presents the first evidence that ERG over expression and PTEN deletion is associated with greater risk of capsular penetration. Although further studies are needed, these results have the potential to change clinical assessment for prostate cancer.

Phase 3 clinical trial investigating the effect of selenium supplementation in men at high-risk for prostate cancer.

PURPOSE: This study was conducted to investigate the effect of Se supplementation on prostate cancer incidence in men at high risk for prostate cancer. METHODS: A Phase 3 randomized, double-blind, placebo-controlled clinical trial was conducted in 699 men at high risk for prostate cancer (prostate specific antigen (PSA) >4 ng/ml and/or suspicious digital rectal examination and/or PSA velocity >0.75 ng/ml/year), but with a negative prostate biopsy. Participants were randomized to receive daily oral placebo (N = 232), 200 µg selenium (N = 234), or 400 µg selenium (N = 233) as selenized yeast. They were followed every 6 months for up to 5 years. The time to diagnosis of prostate cancer was compared between treatment groups using the Cox proportional hazards model. RESULT: Compared to placebo, the hazard ratios [95% confidence intervals] for risk of developing prostate cancer in the selenium 200 µg/day or the selenium 400 µg/day group were 0.94 [0.52, 1.7] and 0.90 [0.48, 1.7], respectively. PSA velocity in the selenium arms was not significantly different from that observed in the placebo group (P = 0.18 and P = 0.17, respectively). CONCLUSION: Selenium supplementation appeared to have no effect on the incidence of prostate cancer in men at high risk. In conjunction with results of other studies, these data indicate that selenium supplementation may not have a role in prostate cancer chemoprevention.

Positive surgical margins at radical prostatectomy predict prostate cancer specific mortality.

PURPOSE: Positive surgical margins in men undergoing radical prostatectomy for prostate cancer are associated with an increased risk of biochemical recurrence. Few data are available on the role of positive surgical margins in prostate cancer specific mortality. Using a large, population based national cancer registry we evaluated the risk of prostate cancer specific mortality associated with margin status. MATERIALS AND METHODS: The SEER cancer registry data for patients diagnosed between 1998 and 2006 were used to identify men undergoing radical prostatectomy for prostate cancer. Margin status, pathological stage, Gleason grade and postoperative radiation therapy were recorded along with demographic data. Multivariate Cox regression analysis was used to estimate the risk of prostate cancer specific mortality associated with positive surgical margins. RESULTS: A total of 65,633 patients comprised the cohort in which 291 (0.44%) prostate cancer specific deaths occurred during an average followup of 50 months. Positive surgical margins were reported in 21.2% of cases and were more common in pT3a than pT2 tumors (44% vs 18%, p <0.001) and higher grade tumors (28% vs 18%, p <0.001). The 7-year disease specific survival rates for those at highest risk for prostate cancer specific mortality (higher grade pT3a) were 97.6% for cases with negative surgical margins and 92.4% for those with positive surgical margins. Positive surgical margins were associated with a 2.6-fold increased unadjusted risk of prostate cancer specific mortality (HR 2.55, 95% CI 2.02-3.21). Positive surgical margins remained an independent predictor of prostate cancer specific mortality on multivariate analysis (HR 1.70, 95% CI 1.32-2.18). CONCLUSIONS: These data demonstrate the independent role of positive surgical margins in prostate cancer specific mortality. These findings support the importance of optimizing surgical techniques to achieve a sound oncological surgical outcome with negative surgical margins when possible.

Potent men undergoing radical prostatectomy: a prospective study measuring sexual health outcomes and the impact of erectile dysfunction treatments.

INTRODUCTION: Radical prostatectomy (RP) can have a significant impact on sexual health. The purpose of this study was to measure changes in sexual health after RP, assess the impact of various treatments for erectile dysfunction, and define an appropriate endpoint for maintaining sexual health after surgery. METHODS: One hundred sixteen men with good preoperative sexual health undergoing RP completed a validated anonymous survey preop and annually thereafter. Subgroup analysis was performed based on the use of erectile dysfunction (ED) treatments. Endpoints for evaluation included an erection adequate for intercourse and a return to baseline in sexual domain scores. RESULTS: Overall there was a significant reduction in scores after surgery for each of the sexual health questions and the function and bother domains. ED treatments providing an erection adequate for intercourse resulted in domain scores significantly higher than those in men unable to achieve such an endpoint, and comparable to those of men returning to good native erectile function, but still lower than preop. Even in men with good preoperative sexual health, with erections adequate for intercourse postop, the return to baseline rate was only 26% in sexual function and 40% in sexual bother. CONCLUSION: RP appears to have a significant impact on sexual health. Overall, ED treatments, when providing a functional erection, improve sexual health scores, even comparable to men returning to spontaneous erectile function. Although, men functioning well prior to surgery infrequently returned to their preoperative level of sexual health, even with return of native erectile function or the successful use of an ED treatment.

Urinary Catheter Management for Nonurologists: A Resident Driven Educational Initiative.

INTRODUCTION: Prevention of catheter associated urinary tract infection relies on timely catheter removal and care of indwelling catheters. Educational and quality improvement initiatives to prevent catheter associated urinary tract infection should address the basics of urinary catheter placement and management. Internal medicine residents are an appropriate target for these efforts and they may lack formal training in these issues. We developed a resident driven orientation session that covers basic Foley catheter management principles called the TIPS (Troubleshooting, Indications and Practice Sessions) program. METHODS: Urology residents at our institution were queried on common consultations for urinary catheter related issues. The incoming intern internal medicine class at our institution completed a pre-TIPS survey that evaluated their baseline urological experience and knowledge. A 1-hour didactic session led by urology residents was followed by hands-on directed practice with mannequins. The web based survey was repeated 1 month later. RESULTS: Of the total of 60 residents 54 (90%) completed the initial survey. In medical school 38 of 54 residents (70%) had never rotated in urology. Upon repeating the survey at 1 month the response rate was 34 of 60 residents (57%). The proportion of residents confident in their ability to troubleshoot catheter problems increased from 50% to 88% (p <0.05). Knowledge of indications, clot retention and proper catheter technique also improved (p <0.05). CONCLUSIONS: A focused educational session about common urological catheter management scenarios resulted in improved internal medicine resident confidence in catheter troubleshooting and knowledge of basic urinary catheter placement indications. These educational sessions may be a method to improve nonurology resident education and awareness of common urological issues.

Health related quality of life outcomes after radical prostatectomy: attention to study design and the patient-based importance of single-surgeon studies.

OBJECTIVE: To define accurately health related quality of life outcomes in men undergoing radical prostatectomy (RP) by a single surgeon. MATERIALS AND METHODS: Since September 1999, men undergoing RP were asked to complete the Medical Outcomes Study Short Form-36 (SF-36) and University of California Los Angeles Prostate Cancer Index preoperatively, returning it to a third party data center. Anonymous surveys were mailed to each patient at 1 and 2 years. RESULTS: We captured 90% and 82% of men at 1 and 2 years, respectively. Mean scores in the SF-36 domains and bowel function/bother were unchanged from preoperative at 1 and 2 years. Urinary function and bother scores were lower at year 1, but stable at year 2. Men wearing > or = 1 pad/d scored significantly lower in urinary function and bother than those noted as pad-free. Pad-free rates were 82% at year 1 and 89% at year 2. Sexual function and bother scores were significantly lower at years 1 and 2. In men younger than 60 years with unilateral nerve-sparing surgery, at 2 years, 50% had erections adequate for intercourse. CONCLUSIONS: This single-surgeon outcomes study after RP showed stability in the SF-36 and bowel domains to 2 years. At 2 years, the vast majority of men were pad-free (89%), and the majority of young men after unilateral nerve-sparing surgery had erections adequate for intercourse (50%). Accurate outcomes measurement can assist in comparing treatments and physicians, and in counseling patients on expected outcomes for localized prostate cancer interventions.

Design and feasibility of integrating personalized PRO dashboards into prostate cancer care.

OBJECTIVE: Patient-reported outcomes (PROs) are a valued source of health information, but prior work focuses largely on data capture without guidance on visual displays that promote effective PRO use in patient-centered care. We engaged patients, providers, and design experts in human-centered design of "PRO dashboards" that illustrate trends in health-related quality of life (HRQOL) reported by patients following prostate cancer treatment. MATERIALS AND METHODS: We designed and assessed the feasibility of integrating dashboards into care in 3 steps: (1) capture PRO needs of patients and providers through focus groups and interviews; (2) iteratively build and refine a prototype dashboard; and (3) pilot test dashboards with patients and their provider during follow-up care. RESULTS: Focus groups (n = 60 patients) prioritized needs for dashboards that compared longitudinal trends in patients' HRQOL with "men like me." Of the candidate dashboard designs, 50 patients and 50 providers rated pictographs less helpful than bar charts, line graphs, or tables (P < .001) and preferred bar charts and line graphs most. Given these needs and the design recommendations from our Patient Advisory Board (n = 7) and design experts (n = 7), we built and refined a prototype that charts patients' HRQOL compared with age- and treatment-matched patients in personalized dashboards. Pilot testing dashboard use (n = 12 patients) improved compliance with quality indicators for prostate cancer care (P < .01). CONCLUSION: PRO dashboards are a promising approach for integrating patient-generated data into prostate cancer care. Informed by human-centered design principles, this work establishes guidance on dashboard content, tailoring, and clinical use that patients and providers find meaningful.

Extreme Gleason Upgrading From Biopsy to Radical Prostatectomy: A Population-based Analysis.

OBJECTIVE: To examine the risk factors associated with the odds of extreme Gleason upgrading at radical prostatectomy (RP) (defined as a Gleason prognostic group score increase of ≥2), we utilized a large, population-based cancer registry. MATERIALS AND METHODS: The Surveillance, Epidemiologic, and End Results database was queried (2010-2011) for all patients diagnosed with Gleason 3 + 3 or 3 + 4 on prostate needle biopsy. Available clinicopathologic factors and the odds of upgrading and extreme upgrading at RP were evaluated using multivariate logistic regression. RESULTS: A total of 12,459 patients were identified, with a median age of 61 (interquartile range: 56-65) and a diagnostic prostate-specific antigen (PSA) of 5.5 ng/mL (interquartile range: 4.3-7.5). Upgrading was observed in 34% of men, including 44% of 7402 patients with Gleason 3 + 3 and 19% of 5057 patients with Gleason 3 + 4 disease. Age, clinical stage, diagnostic PSA, and % prostate needle biopsy cores positive were independently associated with odds of any upgrading at RP. In baseline Gleason 3 + 3 disease, extreme upgrading was observed in 6%, with increasing age, diagnostic PSA, and >50% core positivity associated with increased odds. In baseline Gleason 3 + 4 disease, extreme upgrading was observed in 4%, with diagnostic PSA and palpable disease remaining predictive. Positive surgical margins were significantly higher in patients with extreme upgrading at RP (P < .001). CONCLUSION: Gleason upgrading at RP is common in this large population-based cohort, including extreme upgrading in a clinically significant portion.

Preliminary Comparative Effectiveness of Robotic Versus Open Radical Cystectomy in Elderly Patients.

INTRODUCTION: Treatment for muscle-invasive bladder cancer (MIBC) remains highly morbid despite improving surgical techniques. As the median age of diagnosis is 73, many patients are elderly at the time of cystectomy. We compare perioperative surgical outcomes in elderly patients undergoing robotic vs open radical cystectomy (RC). MATERIALS AND METHODS: Patients >75 years at time of RC were identified. Demographic, clinicopathologic, and perioperative variables were examined. Estimated blood loss (EBL) and length of stay (LOS) data were collected with multivariate linear regression analysis performed to assess whether technique was independently associated with outcomes. RESULTS: Eighty-seven patients >75 years of age underwent cystectomy for MIBC (58 open, 29 robotic). Mean age was 79.6 (±3.2) and 79.2 (±3.5) for open and robotic groups, respectively (p = 0.64). There were no significant differences in baseline comorbidities, clinical or pathologic stage, or use of neoadjuvant chemotherapy. The mean number of lymph nodes removed was similar (p = 0.08). Robotic cystectomy had significantly longer mean OR times (p < 0.001). On multivariate analyses, robotic surgery was associated with -389cc less EBL (95% CI -547 to -230, p < 0.001) and a -1.5-day-shortened LOS (95%CI -2.9 to -0.2, p = 0.02) compared with open surgery. There were no significant differences in surgical complications or 90-day readmission rates between the two groups. CONCLUSIONS: Robotic cystectomy is safe and feasible in an elderly population. We observed longer OR times with robotic surgery, but with decreased EBL, shorter hospital stays, and comparable complication and readmission rates with open RC. Larger prospective studies are required to confirm these findings.

Relevance of graph literacy in the development of patient-centered communication tools.

OBJECTIVE: To determine the literacy skill sets of patients in the context of graphical interpretation of interactive dashboards. METHODS: We assessed literacy characteristics of prostate cancer patients and assessed comprehension of quality of life dashboards. Health literacy, numeracy and graph literacy were assessed with validated tools. We divided patients into low vs. high numeracy and graph literacy. We report descriptive statistics on literacy, dashboard comprehension, and relationships between groups. We used correlation and multiple linear regressions to examine factors associated with dashboard comprehension. RESULTS: Despite high health literacy in educated patients (78% college educated), there was variation in numeracy and graph literacy. Numeracy and graph literacy scores were correlated (r=0.37). In those with low literacy, graph literacy scores most strongly correlated with dashboard comprehension (r=0.59-0.90). On multivariate analysis, graph literacy was independently associated with dashboard comprehension, adjusting for age, education, and numeracy level. CONCLUSIONS: Even among higher educated patients; variation in the ability to comprehend graphs exists. PRACTICE IMPLICATIONS: Clinicians must be aware of these differential proficiencies when counseling patients. Tools for patient-centered communication that employ visual displays need to account for literacy capabilities to ensure that patients can effectively engage these resources.

External beam radiation therapy and abiraterone in men with localized prostate cancer: safety and effect on tissue androgens.

PURPOSE: Optimizing androgen suppression may provide better control of localized prostate cancer (PCa). Numerous trials have supported the benefit of combining androgen deprivation therapy with definitive radiation therapy in men with locally advanced or high-grade disease. Addition of abiraterone to luteinizing hormone-releasing hormone agonist (LHRHa) with radiation has not been reported. We examined the safety of this combination as well as its impact on androgen suppression. METHODS AND MATERIALS: A prospective, phase 2 study was conducted in men with localized PCa treated with 6 months of neoadjuvant and concurrent abiraterone with LHRHa and radiation. Duration of adjuvant LHRHa was at the discretion of the treating clinician. Prostate biopsy assays were obtained prior to the start of therapy and prior to radiation. Sera and tissue androgen levels were measured by liquid chromatography-tandem mass spectrometry. RESULTS: A total of 22 men with intermediate- (n=3) and high-risk PCa (n=19) received study therapy. Sixteen men completed the intended course of abiraterone, and 19 men completed planned radiation to 77.4 to 81 Gy. Radiation to pelvic nodes was administered in 20 men. The following grade 3 toxicities were reported: lymphopenia (14 patients), fatigue (1 patient), transaminitis (2 patients), hypertension (2 patients), and hypokalemia (1 patient). There were no grade 4 toxicities. All 21 men who complied with at least 3 months of abiraterone therapy had a preradiation prostate-specific antigen (PSA) concentration nadir of <0.3 ng/mL. Median levels of tissue androgen downstream of CYP17A were significantly suppressed after treatment with abiraterone, and upstream steroids were increased. At median follow-up of 21 months (range: 3-37 months), only 1 patient (who had discontinued abiraterone at 3 months) had biochemical relapse. CONCLUSIONS: Addition of abiraterone to LHRHa with radiation is safe and achieves effective prostatic androgen suppression. Preliminary analysis of the clinical data is also promising, with excellent PSA nadir and no relapse to date in this high-risk population.

Different phenotypes in human prostate cancer: alpha6 or alpha3 integrin in cell-extracellular adhesion sites.

The distribution of alpha6/alpha3 integrin in adhesion complexes at the basal membrane in human normal and cancer prostate glands was analyzed in 135 biopsies from 61 patients. The levels of the polarized alpha6/alpha3 integrin expression at the basal membrane of prostate tumor glands were determined by quantitative immunohistochemistry. The alpha6/alpha3 integrin expression was compared with Gleason sum score, pathological stage, and preoperative serum prostate-specific antigen (PSA). The associations were assessed by statistical methods. Eighty percent of the tumors expressed the alpha6 or alpha3 integrin and 20% was integrin-negative. Gleason sum score, but not serum PSA, was associated with the integrin expression. Low Gleason sum score correlated with increased integrin expression, high Gleason sum score with low and negative integrin expression. Three prostate tumor phenotypes were distinguished based on differential integrin expression. Type I coexpressed both alpha6 and alpha3 subunits, type II exclusively expressed alpha6 integrin, and type III expressed alpha3 integrin only. Fifteen cases were further examined for the codistribution of vinculin, paxillin, and CD 151 on frozen serial sections using confocal laser scanning microscopy. The alpha6/alpha3 integrins, CD151, paxillin, and vinculin were present within normal glands. In prostate carcinoma, alpha6 integrin was colocalized with CD 151, but not with vinculin or paxillin. In tumor phenotype I, the alpha6 subunit did not colocalize with the alpha subunit indicating the existence of two different adhesion complexes. Human prostate tumors display on their cell surface the alpha6beta1 and/or alpha3beta1 integrins. Three tumor phenotypes associated with two different adhesion complexes were identified, suggesting a reorganization of cell adhesion structures in prostate cancer.

Effect of patient age on early detection of prostate cancer with serum prostate-specific antigen and digital rectal examination.

This study was designed to determine the effects of age by decade on the efficacy of digital rectal examination (DRE) and serum prostate-specific antigen (PSA) for early detection of prostate cancer in men aged fifty and over. A prospective multicenter clinical trial was conducted at six university centers. All 6,630 male volunteers underwent a serum PSA (Hybritech, Tandem) determination and DRE. Quadrant biopsies of the prostate were performed if PSA was > 4 ng/mL or DRE suspicious. A total of 1,167 biopsies were performed, and 264 cancers were detected. The cancer detection rate increased from 3 percent in men aged fifty to fifty-nine to 14 percent in men eighty years or older (p < 0.0001). PSA detected significantly more of the total cancers than DRE at all age ranges (p < 0.05). The positive predictive values (PPV) for PSA were 32 percent (50-59 years), 30 percent (60-69 years), 34 percent (70-79 years), and 38 percent (80+ years). The corresponding PPVs for DRE were 17 percent, 21 percent, 25 percent, and 38 percent. Eighteen percent of the cancers were detected solely by DRE, whereas 45 percent of cancers were detected solely by PSA. Thus, the use of both tests in combination provided the highest rate of detection in all age groups. One hundred-sixty patients underwent radical prostatectomy and pathologic staging. Cancer was organ-confined in 74 percent (25/34) of men aged fifty to fifty-nine, 76 percent (65/86) of men aged sixty to sixty-nine, and 60 percent (24/40) of men aged seventy or over (chi 2, < 70 vs. > or = 70, p < 0.05). Early detection programs yield a lower, yet still substantial, cancer detection rate in younger men, and there is a greater likelihood for detection of organ-confined disease in this age range. Younger men have the longest projected life expectancy and, therefore, the most to gain from early prostate cancer detection.

User-centered design of quality of life reports for clinical care of patients with prostate cancer.

BACKGROUND: Primary treatment of localized prostate cancer can result in bothersome urinary, sexual, and bowel symptoms. Yet clinical application of health-related quality-of-life (HRQOL) questionnaires is rare. We employed user-centered design to develop graphic dashboards of questionnaire responses from patients with prostate cancer to facilitate clinical integration of HRQOL measurement. METHODS: We interviewed 50 prostate cancer patients and 50 providers, assessed literacy with validated instruments (Rapid Estimate of Adult Literacy in Medicine short form, Subjective Numeracy Scale, Graphical Literacy Scale), and presented participants with prototype dashboards that display prostate cancer-specific HRQOL with graphic elements derived from patient focus groups. We assessed dashboard comprehension and preferences in table, bar, line, and pictograph formats with patient scores contextualized with HRQOL scores of similar patients serving as a comparison group. RESULTS: Health literacy (mean score, 6.8/7) and numeracy (mean score, 4.5/6) of patient participants was high. Patients favored the bar chart (mean rank, 1.8 [P = .12] vs line graph [P < .01] vs table and pictograph); providers demonstrated similar preference for table, bar, and line formats (ranked first by 30%, 34%, and 34% of providers, respectively). Providers expressed unsolicited concerns over presentation of comparison group scores (n = 19; 38%) and impact on clinic efficiency (n = 16; 32%). CONCLUSION: Based on preferences of prostate cancer patients and providers, we developed the design concept of a dynamic HRQOL dashboard that permits a base patient-centered report in bar chart format that can be toggled to other formats and include error bars that frame comparison group scores. Inclusion of lower literacy patients may yield different preferences.

Prostate cancer that is within 0.1 mm of the surgical margin of a radical prostatectomy predicts greater likelihood of recurrence.

Surgical margin status at prostatectomy is an important predictor of biochemical recurrence (BCR). The current convention is to categorize a margin as negative if tumor cells are not at the inked margin, even if they are within a few cells of the margin. We hypothesized that cancer within 0.1 mm of the margin conferred an increased risk for BCR. We determined the risk for BCR on the bass of surgical margin status in a cohort of 1588 patients who underwent radical prostatectomy for prostate cancer (PCa) between 1998 and 2011. Surgical margins were categorized as positive, close (<0.1 mm from tumor cells), or negative. Multivariate hazard ratios (HRs) for BCR were determined by margin status. We identified 1588 patients, of whom 193 had PCa recurrence. The margin status was negative in 1058 (67%), close in 232 (15%), and positive in 298 (19%). Cancer that was close to the margin was a significant and independent predictor of BCR (HR 1.53; 95% confidence interval, 1.00-2.32) and was not statistically different than a positive surgical margin (HR 2.10; 95% confidence interval, 1.48-2.99). Cancer that is within 0.1 mm of the surgical margin of a prostatectomy is associated with an increased risk for PCa recurrence. Patients with that margin status may be reasonable candidates for adjuvant local therapy.
