Abstract
Importance Understanding the adverse effects of contemporary approaches to localized prostate cancer treatment could inform shared decision making. Objective To compare functional outcomes and adverse effects associated with radical prostatectomy, external beam radiation therapy (EBRT), and active surveillance. Design, Setting, and Participants Prospective, population-based, cohort study involving 2550 men (≤80 years) diagnosed in 2011-2012 with clinical stage cT1-2, localized prostate cancer, with prostate-specific antigen levels less than 50 ng/mL, and enrolled within 6 months of diagnosis. Exposures Treatment with radical prostatectomy, EBRT, or active surveillance was ascertained within 1 year of diagnosis. Main Outcomes and Measures Patient-reported function on the 26-item Expanded Prostate Cancer Index Composite (EPIC) 36 months after enrollment. Higher domain scores (range, 0-100) indicate better function. Minimum clinically important difference was defined as 10 to 12 points for sexual function, 6 for urinary incontinence, 5 for urinary irritative symptoms, 5 for bowel function, and 4 for hormonal function. Results The cohort included 2550 men (mean age, 63.8 years; 74% white, 55% had intermediate- or high-risk disease), of whom 1523 (59.7%) underwent radical prostatectomy, 598 (23.5%) EBRT, and 429 (16.8%) active surveillance. Men in the EBRT group were older (mean age, 68.1 years vs 61.5 years, P < .001) and had worse baseline sexual function (mean score, 52.3 vs 65.2, P < .001) than men in the radical prostatectomy group. At 3 years, the adjusted mean sexual domain score for radical prostatectomy decreased more than for EBRT (mean difference, -11.9 points; 95% CI, -15.1 to -8.7). The decline in sexual domain scores between EBRT and active surveillance was not clinically significant (-4.3 points; 95% CI, -9.2 to 0.7). Radical prostatectomy was associated with worse urinary incontinence than EBRT (-18.0 points; 95% CI, -20.5 to -15.4) and active surveillance (-12.7 points; 95% CI, -16.0 to -9.3) but was associated with better urinary irritative symptoms than active surveillance (5.2 points; 95% CI, 3.2 to 7.2). No clinically significant differences for bowel or hormone function were noted beyond 12 months. No differences in health-related quality of life or disease-specific survival (3 deaths) were noted (99.7%-100%). Conclusions and Relevance In this cohort of men with localized prostate cancer, radical prostatectomy was associated with a greater decrease in sexual function and urinary incontinence than either EBRT or active surveillance after 3 years and was associated with fewer urinary irritative symptoms than active surveillance; however, no meaningful differences existed in either bowel or hormonal function beyond 12 months or in in other domains of health-related quality-of-life measures. These findings may facilitate counseling regarding the comparative harms of contemporary treatments for prostate cancer.

Abstract
PURPOSE "Me-too" drugs are new pharmaceuticals with the mechanism of action of an existing drug and are considered less innovative than breakthrough drugs. The objective of this study was to evaluate whether the adoption patterns of the breakthrough drug sitagliptin and the "me-too" drug saxagliptin differed; and to assess whether the patterns differed between Medicare stand-alone (PDP) and Medicare-Advantage Part D (MA-PD) plans. METHODS Pharmacy claims from a 5% random sample of Medicare Part D beneficiaries were used to identify all prescriptions filled for sitagliptin (breakthrough drug) and saxagliptin ("me-too" drug) between October 1, 2006 and December 31, 2011. The number of new sitagliptin and saxagliptin users by month and type of plan were plotted, and Bass diffusion models were constructed to estimate the rate of diffusion. RESULTS Sitagliptin had a longer adoption life than saxagliptin, and its adoption was quicker among MA-PD than PDP beneficiaries: it peaked at 51 and 66.7 months after its approval, respectively. However, the adoption of saxagliptin did not differ by type of plan: it peaked at 20.5 months in PDP and 22.9 months in MA-PD. At the end of our study, the market share of the innovative drug sitagliptin measured as the cumulative number of users since market entry was almost nine times higher than the "me-too" drug, saxagliptin. CONCLUSIONS The breakthrough drug sitagliptin had a much longer adoption life compared to the "me-too" drug saxagliptin, and the breakthrough drug sitagliptin was adopted quicker among managed care plans compared to PDP plans.

Abstract
BACKGROUND AND PURPOSE Ureteropelvic junction obstruction is a common urologic condition that accounts for approximately $12 million in inpatient spending annually. Few studies have assessed the costs related to treatment. We sought to examine the cost of care for patients treated for ureteropelvic junction obstruction. PATIENTS AND METHODS We used the MarketScan® database to identify adults from 18 to 64 years old treated with minimally invasive pyeloplasty, open pyeloplasty, and endopyelotomy for ureteropelvic junction obstruction between 2002 and 2010. Our primary outcome was total expenditures related to the surgical episode, defined as the period from 30 days prior until 30 days after the index surgery. We fit a multinomial linear regression model to evaluate cost of the surgical episode, adjusting for age, gender, comorbidity, benefit plan type, and region of residence. RESULTS We identified 1251 endopyelotomies, 717 open pyeloplasties, and 1048 minimally invasive pyeloplasties. The adjusted mean costs were $16,379 for endopyelotomy, $22,421 for open pyeloplasty, and $22,843 for minimally invasive pyeloplasty (p < 0.0001, ANCOVA). Both open and minimally invasive pyeloplasties were more costly than endopyelotomy (both p < 0.0001, comparison between groups). However, the cost of open and minimally invasive pyeloplasties was similar (p = 0.57, comparison between groups). CONCLUSIONS Among the three treatments, endopyelotomy was the least expensive in the immediate perioperative period. Open and minimally invasive pyeloplasties were similar in cost, but both more expensive than endopyelotomies. The similar cost between the two pyeloplasty approaches provides additional evidence that minimally invasive pyeloplasty should be considered the standard treatment for ureteropelvic junction obstruction.

Abstract
Intensity-modulated radiation therapy (IMRT), an innovative treatment option for prostate cancer, has rapidly diffused over the past decade. To inform our understanding of racial disparities in prostate cancer treatment and outcomes, this study compared diffusion of IMRT in African American (AA) and Caucasian American (CA) prostate cancer patients during the early years of IMRT diffusion using the Surveillance, Epidemiology and End Results (SEER)-Medicare linked database. A retrospective cohort of 947 AA and 10,028 CA patients diagnosed with localized prostate cancer from 2002 through 2006, who were treated with either IMRT or non-IMRT as primary treatment within 1 year of diagnoses was constructed. Logistic regression was used to examine potential differences in diffusion of IMRT in AA and CA patients, while adjusting for socioeconomic and clinical covariates. A significantly smaller proportion of AA compared with CA patients received IMRT for localized prostate cancer (45% vs. 53%, p < .0001). Racial differences were apparent in multivariable analysis though did not achieve statistical significance, as time and factors associated with race (socioeconomic, geographic, and tumor related factors) explained the preponderance of variance in use of IMRT. Further research examining improved access to innovative cancer treatment and technologies is essential to reducing racial disparities in cancer care.

Abstract
OBJECTIVE Robotic prostatectomy has rapidly disseminated over the past decade. How managed care, thought by many to be a barrier to new technology, influences the dissemination of robotics is unknown. We sought to better understand the relationship between a market's managed-care penetration and the dissemination of robotic prostatectomy. METHODS We used SEER-Medicare data from 2003 through 2007 to identify men ≥66 years of age treated with radical prostatectomy for prostate cancer. We categorized Health Service Areas (HSAs) according to the degree of managed-care penetration (ie, low vs high). We assessed adoption of robotic prostatectomy and utilization among adopting HSAs using Cox proportional-hazards and Poisson regression models, respectively. RESULTS Compared with markets with little managed care, highly penetrated markets had more racial diversity (24% vs 15% nonwhite, P < .01), higher population densities (1987 vs 422 people/square mile, P < .01), and higher median incomes ($49 374 vs $36 236, P < .01). Robotic prostatectomy adoption and utilization increased over time in both HSA categories. Compared with low managed-care markets, those with high managed care adopted robotic prostatectomy more rapidly (eg, probability 0.37 [low] vs 0.52 [high] in 2007; P < .01). However, the postadoption utilization of robotic prostatectomy was constrained in these highly penetrated markets (eg, probability 0.66 [low] vs 0.52 [high] in 2007; P < .01). CONCLUSIONS High managed-care penetration was associated with more rapid robotic prostatectomy adoption. However, once adopted, utilization increased more slowly in these markets. Understanding this paradox is important as more technologies are unveiled in an increasingly cost-conscious health care environment.

Radical Cystectomy after BCG Immunotherapy for High-Risk Nonmuscle-Invasive Bladder Cancer in Patients with Previous Prostate Radiotherapy. ISRN UROLOGY 2013; 2013:405064. [PMID: 23956880 PMCID: PMC3730135 DOI: 10.1155/2013/405064] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/22/2013] [Accepted: 06/20/2013] [Indexed: 11/17/2022]
Abstract
Purpose. Intravesical Bacillus Calmette-Guerin (BCG) immunotherapy is indicated for high-grade nonmuscle-invasive bladder cancer (NMIBC). The efficacy of BCG in patients with a history of previous pelvic radiotherapy (RT) may be diminished. We evaluated the outcomes of radical cystectomy for BCG-treated recurrent bladder cancer in patients with a history of RT for prostate cancer (PC). Methods. A retrospective chart review was performed to identify patients with primary NMIBC. We compared the outcomes of three groups of patients who underwent radical cystectomy for BCG-refractory NMIBC: those with a history of RT for PC, those who previously underwent radical prostatectomy (RP), and a cohort without PC or RT exposure. Results. From 1996 to 2008, 53 patients underwent radical cystectomy for recurrent NMIBC despite BCG. Those with previous pelvic RT were more likely to have a higher pathologic stage and decreased recurrence-free survival compared to the groups without prior RT exposure. Conclusion. Response rates for intravesical BCG therapy may be impaired in those with prior prostate radiotherapy. Patients with a history of RT who undergo radical cystectomy after failed BCG are more likely to be pathologically upstaged and have decreased recurrence-free survival. Earlier consideration of radical cystectomy may be warranted for those with NMIBC who previously received RT for PC.
