Prostate cancer navigation: initial experience and association with time to care.

OBJECTIVE: To evaluate factors associated with use of patient navigation in a prostate cancer population and identify whether navigation is associated with prolonged time to care. Cancer patient navigation has been shown to improve access to cancer screening, diagnosis, and treatment, but little is known about patient navigation in prostate cancer care. METHODS: All men diagnosed with localized prostate cancer between 2009 and 2015 were abstracted from the MaineHealth multi-specialty tumor registry. Regression analyses controlling for patient-, disease-, and system-level factors evaluated characteristics associated with navigation utilization. The association between navigation utilization, barriers to care, and longer time to treatment was assessed with Cox proportional hazards regression. RESULTS: Of the patient population (n = 1587), 85% of men were navigated. Navigation use was associated with earlier year of diagnosis, treatment by a high-volume urologist, and lower risk disease (p < 0.05). Treatment delay was associated with low-risk disease (vs: intermediate OR 0.62, 95% CI 0.46-0.85 and high OR 0.16, 95% CI 0.1-0.25) and receipt of navigation services (OR 1.65, 95% CI 1.12-2.45) but not distance to care, insurance, or treatment choice. CONCLUSIONS: We observed that patients with low-risk prostate cancer were more likely to utilize navigation, but traditional barriers to care were not associated with utilization. Navigation was associated with longer time to treatment, which likely reflects clinically appropriate delays associated with greater shared decision making. Time to treatment may not be the ideal metric for evaluating navigation in prostate cancer; shared decision making, patient satisfaction, and psychosocial outcomes may be more appropriate.

Societal costs of localized renal cancer surgery.

INTRODUCTION: Hospital-related costs of renal cancer surgery have been described, but the societal costs of surgery-related lost productivity are poorly understood. We estimated the societal cost of renal cancer surgery by assessing surgery-related time off work (TOW) taken by patients and their caretakers. MATERIALS AND METHODS: A total of 413 subjects who underwent partial or radical nephrectomy enrolled in an IRB-approved prospective study received an occupational survey assessing employment status, work physicality, income, surgery-related TOW, and caretaker assistance. We excluded subjects with incomplete occupational information or metastatic disease. We estimated potential wages lost using individual income and TOW, and used logistic regression to evaluate for factors predictive of TOW > 30 days. RESULTS: Of the 219 subjects who responded, 138 were employed at time of surgery. Ninety-seven subjects returned to work, met the inclusion criteria, and were analyzed. Mean age was 54 and 56% of subjects had sedentary jobs. TOW ranged from 7 to 92 days; mean and median TOW was 35 and 33 days, respectively and 58% of subjects took > 30 days off. Mean potential wages lost for TOW was $10,152. Eighty-three percent of subjects had at least one caretaker take TOW (mean/median caretaker TOW: 11/7 days, respectively) to assist in recovery. Subjects with sedentary jobs were less likely to take > 30 days off (OR 0.30; 95% CI 0.09-0.99). CONCLUSIONS: Most renal cancer surgery patients take over 1 month off work. Recognizing the associated societal costs may allow better adjustment of patient expectations, and more comprehensive cost-effectiveness analyses in renal cancer care.

Pathologic nodal downstaging in men with clinically involved lymph nodes undergoing radical prostatectomy: Implications for definitive locoregional therapy.

A prostate cancer (CaP) patient with nonmetastatic but clinical positive lymph nodes (cN+) represents a difficult clinical scenario. We compare overall survival (OS) between cN+ men that underwent radical prostatectomy (RP) and were found to have negative node status (pN) with those found to have positive nodal status (pN+), and assess predictors of discordant nodal status. We queried the National Cancer Data Base between 2004 and 2015 for patients that were cT1-3 cN+ cM0 CaP treated with RP. Patients with 0 nodes, cT4, or cM1 disease were excluded. We compared groups based on pathologic nodal status: Discordant (cN+ -> pN) & Concordant (cN+ -> pN+). Kaplan Meier estimations were used to compare OS. Logistic regression was used to determine possible predictors of nodal status. We find that of 6470 cN+ patients, 1,367 (21.1%) underwent RP, 866 (13.4%) had confirmed nodal status. Discordant status was found in 159 (18.4%) and concordant staging in 707 (81.6%). Differences exist in PSA at diagnosis (7.3 vs. 11.2), biopsy group, # of nodes examined (7 vs. 10), race, and Charlson index. Discordant staging had longer OS compared to Concordant staging (P = 0.007) and similar OS to a 3:1 matched cohort of high risk localized CaP patients used as reference (P = 0.46). Lower Gleason Score (GG1-3) was associated with an increased likelihood of discordant staging. Clinical nodal staging is associated with a substantial false positive rate. Discordant status had better OS than Concordant status and similar OS to matched patients with localized CaP. Clinical nodal staging may inappropriately lead to noncurative therapy in a substantial number of men with potentially curable disease.

Robot-assisted radical prostatectomy: learning rate analysis as an objective measure of the acquisition of surgical skill.

OBJECTIVE: To adapt an industrial definition of learning-curve analysis to surgical learning, and elucidate the rate at which experienced open surgeons acquire skills specific to robot-assisted radical prostatectomy (RARP) at a community-based medical centre. PATIENTS, SUBJECTS AND METHODS: The total procedure time (TPT) of the first 75 RARPs, performed by three surgeons experienced with retropubic RP, was analysed to determine the point at which their learning rate stabilised. Operative characteristics were compared before and after this point to isolate the plateau of learning rate as a mark of acquiring surgical skill. The operative characteristics examined were TPT, estimated blood loss (EBL), bladder neck contractures (BNC), positive margins (PM) and length of hospital stay (LOS). RESULTS: The mean rate of TPT decrease, for procedures 1-75, was 13.4% per doubling of RARPs performed. After the first 25 procedures the TPT decreased at a rate of 1.8% per doubling, not significantly different from 0 (P > 0.05). There was no significant difference between procedures 1-25 and 26-75 in rates of EBL, BNC and PM. There was a significant change for all surgeons in TPT, with a mean of 303.1 min (RARPs 1-25) vs 213.6 min (26-75) (P < 0.001), and LOS, of 2.1 days (1-25) vs 1.4 days (26-75) (P < 0.001). CONCLUSIONS: An industrial definition of learning-curve analysis can be adapted to provide an objective measure of learning RARP. The average learning rate for RARP was found to plateau by the 25th procedure. Also, the learning rate plateau can serve as an objective measure of the acquisition of surgical skill.

Review of the comparative effectiveness of radical prostatectomy, radiation therapy, or expectant management of localized prostate cancer in registry data.

Evidence regarding the effectiveness of treatment for prostate cancer is primarily based on randomized controlled trials. Long-term outcomes are generally difficult to evaluate within experimental studies and may benefit from large pools of observational data. We conducted a systematic review of administrative and registry studies to evaluate the comparative effectiveness of treatment for clinically localized prostate cancer on overall and prostate-cancer specific mortality. MATERIALS AND METHODS: In accordance with the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P, 2015), we conducted a systematic search of Ovid Medline and Embase (1946-February 2017) and identified studies that evaluated the relationship between types of treatment for localized prostate cancer and mortality. Additional articles were identified through manual search. Randomized, prospective, and single institution studies were excluded. The risk of bias for each study was evaluated with the Newcastle Ottawa scale. Multivariable adjusted hazard ratios were reported to evaluate overall and cancer-specific mortality. RESULTS: We screened 4,721 studies and included for review, 19 that were published between 2001 and 2015. The pooled population included 228,444 patients. Countries of origin included the United States, Canada, China, Switzerland, the Netherlands, and Sweden, and the sources included administrative (n = 6) and cancer registry or prostate databases (n = 11). Overall and cancer-specific mortality were lowest among definitive treatment arms as compared to conservative therapy with no treatment, observation, or active surveillance. Radiotherapy was associated with worse overall and cancer-specific mortality than radical prostatectomy. CONCLUSION: Although observational studies using large, population-based cohorts have the potential for bias, we found consistent evidence that high-quality observational studies may be used to evaluate the comparative effectiveness of prostate cancer treatment. Methodologic limitations of observational data should be considered.

Systematic Review of the Volume-Outcome Relationship for Radical Prostatectomy.

CONTEXT: Radical prostatectomy (RP) is one of the most complex urological procedures performed. Higher surgical volume has been found previously to be associated with better patient outcomes and reduced costs to the health care system. This has resulted in some regionalization of care toward high-volume facilities and providers; however, the preponderance of RPs is still performed at low-volume institutions. OBJECTIVE: To provide an updated systematic review of the association of hospital and surgeon volume on patient and system outcomes after RP, including robot-assisted RP. EVIDENCE ACQUISITION: A systematic review of literature was undertaken, searching PubMed (1959-2016) for original articles. Selection criteria included RP, hospital and/or surgeon volumes as predictor variables, categorization of hospital and/or surgeon volumes, and measurable end points. EVIDENCE SYNTHESIS: Overall 49 publications fulfilled the inclusion criteria. Most of the studies demonstrated that higher-volume surgeries are associated with better outcomes including reduced mortality, morbidity, postoperative complications, length of stay, readmission, and cost-associated factors. The volume-outcome relationship is maintained in robotic surgery. Eleven studies assessed hospital and surgeon volume simultaneously, and findings reflect that neither is an independent predictor variable affecting outcomes. The studies varied in how volume cutoffs were categorized as well as how the volume-outcome relationship was methodologically evaluated. CONCLUSIONS: Contemporary evidence continues to support the relationship between high-volume surgeries with improved RP outcomes. Recent studies demonstrate that the volume-outcome relationship applies to robot-assisted RP and may be applied for potential cost savings in health care. An increase in the number of international studies suggests reproducibility of the association. Although regionalization of surgical care remains a contentious issue, there is an increasing body of evidence that short-term outcomes are improved at high-volume centers for RP. PATIENT SUMMARY: This systematic review of the latest literature found that higher surgical volume was associated with improved outcomes for radical prostatectomy.

Urologic Emergencies.

The diagnosis and management of urologic emergencies are incorporated into the basic training of all urology residents. In institutions without access to urologic services, it is usually left to the General Surgeon or Emergency Medicine physician to provide timely care. This article discusses diagnoses that are important to recognize and treatment that is practically meaningful for the non-Urologist to identify and treat. The non-Urology provider, after reading this article, will have a better understanding and a higher comfort level with treating patients with urologic emergencies.
