Racial disparities in stage at bladder cancer diagnosis in the US Veterans Affairs healthcare system.

OBJECTIVE: To describe patient characteristics and pathological stage at bladder cancer (BCa) diagnosis in a diverse population within a national, equal-access healthcare system. METHODS: This retrospective cohort study identified 15 966 men diagnosed with BCa in the Veterans Affairs (VA) healthcare system from 2000 to 2020. The primary outcome was pathological stage at diagnosis, determined by index transurethral resection of bladder tumour. Logistic regression was used to assess the relationship between race and stage. Competing risk models tested the association between race and BCa-specific mortality with cumulative incidence estimates. RESULTS: Of 15 966 BCa patients, 12 868 (81%), 1726 (11%), 493 (3%) and 879 (6%) were White, Black, Hispanic and Other race, respectively. Black patients had significantly higher muscle-invasive bladder cancer (MIBC) rates than White patients (35% vs 32%; P = 0.009). In multivariable analysis, the odds of presenting with MIBC did not differ significantly between Black and White patients (odds ratio [OR] 1.10, 95% confidence interval [CI] 0.98-1.22) or between Hispanic patients (OR 0.82, 95% CI 0.67-1.01) and White patients. Compared to White patients, Black patients had a similar risk of BCa-specific mortality (hazard ratio [HR] 0.89, 95% CI 0.75-1.06), whereas Hispanic patients had a lower risk (HR 0.56, 95% CI 0.38-0.82). CONCLUSIONS: Black patients presented with the highest rates of de novo MIBC. However, in a large, equal-access healthcare system, this did not result in a difference in BCa-specific mortality. In contrast, Hispanic patients had lower risks of MIBC and BCa-specific mortality.

Geographic distribution of racial differences in mortality in muscle-invasive bladder cancer patients: an opportunity for improvement.

OBJECTIVES: To determine the geographic distribution of muscle-invasive bladder cancer mortality according to race in the United States (US). African Americans (AAs) have up to two times the risk of bladder cancer mortality compared to Caucasians. Bladder cancer mortality increases exponentially once it invades the muscle. Geographic heterogeneity in bladder cancer mortality according to race remains to be determined. DESIGN: Analysis of Surveillance, Epidemiology, and End Results (SEER)-Medicare data for 6,044 patients aged 66-85 diagnosed with clinical stage T2-T4 N0M0 bladder cancer from 1 January 2002 to 31 December 2011. Fine and Gray-competing risks regression models were used to assess the association of race with bladder cancer-specific mortality (BCSM) according to tumor registry. RESULTS: Out of 6,044 patients, 5,408 (89.5%) were Caucasian, 352 (5.82%) were non-Hispanic AA, 85 (1.4%) were Hispanic, and 199 (3.29%) were other. Of the 18 registries, AAs with bladder cancer were largely concentrated in Louisiana (19%), New Jersey (17.9%), and Georgia (17.6%). New Jersey was the only registry where AAs had increased risk of BCSM than Caucasians and only for stage T2 disease: (AHR, 1.74; 95% CI 1.22-2.47, p = 0.002). According to treatment, AAs in New Jersey had worse BCSM than Caucasians when they underwent radical cystectomy (AHR, 2.05; 95% CI 1.26-3.35, p = 0.0039) and radiotherapy or chemotherapy alone (AHR, 1.55; 95% CI 1.03-2.35, p = 0.0367). CONCLUSIONS: We observed geographic variation in bladder cancer mortality which impacted only one registry with one of the largest population of AAs. These findings support further investigation into the social determinants of race (i.e., socioeconomic status and distance to healthcare facility) and culturally centered healthcare decision making which may drive these results.

Race reporting and disparities regarding clinical trials in bladder cancer: a systematic review.

PURPOSE: To systematically review the literature to investigate racial disparities among bladder cancer clinical trial enrollees. METHODS: A systematic review was conducted using Ovid, MEDLINE® to identify clinical trials between 1970 and 2020. Articles were reviewed and were included if they assessed race in their outcomes reporting among bladder cancer patients enrolled in clinical trials. The review was conducted in accordance with the PRISMA statement. RESULTS: We identified 544 clinical trials meeting our initial search criteria, with only 24 (4.4%) studies reporting racial demographic data. Enrollees were largely Caucasian (81-98%), with a strikingly small proportion of enrolled patients consisting of African-Americans (2-8%) and Hispanics (2-5%). Only one of the studies reported results on the efficacy and safety/tolerability of the tested treatment separately for racial groups and performed analyses stratified by race. CONCLUSION: Race is poorly studied in bladder cancer clinical trials. Trial cohorts may not reflect multicultural populations. The potential association between race and efficacy, safety or tolerability of the tested interventions is unknown. Given the up to twofold increase in bladder cancer-specific death among African-Americans, further research is needed to address the impact of race in clinical trials, while encompassing socioeconomic factors and disease risk factor exposures.

Critical analysis of quality of life and cost-effectiveness of enhanced recovery after surgery (ERAS) for patient's undergoing urologic oncology surgery: a systematic review.

PURPOSE: Enhanced recovery after surgery (ERAS) protocols have been implemented across a variety of disciplines to improve outcomes. Herein we describe the impact of ERAS on quality of life (QOL) and cost for patients undergoing urologic oncology surgery. METHODS: A systematic literature search using the MEDLINE, Scopus, Clinictrials.gov, and Cochrane Review databases for studies published between 1946 and 2020 was conducted. Articles were reviewed and assigned a risk of bias by two authors and were included if they addressed ERAS and either QOL or cost-effectiveness for patients undergoing urologic oncology surgery. RESULTS: The literature search yielded a total of 682 studies after removing duplicates, of which 10 (1.5%) were included in the review. Nine articles addressed radical cystectomy, while one addressed ERAS and QOL for laparoscopic nephrectomy. Six publications assessed the impact of ERAS on QOL domains. Questionnaires used for assessment of QOL varied across studies, and timing of administration was heterogeneous. Overall, ERAS improved patient QOL during early phases of recovery within the realms of bowel function, physical/social/cognitive functioning, sleep and pain control. Costs were assessed in 4 retrospective studies including 3 conducted in the United States and one from China all addressing radical cystectomy. Studies demonstrated either decreased costs associated with ERAS as a result of decreased length of stay or no change in cost based on ERAS implementation. CONCLUSION: While limited studies are published on the subject, ERAS implementation for radical cystectomy and laparoscopic nephrectomy improved patient-reported QOL during early phases of recovery. For radical cystectomy, there was a decreased or neutral overall financial cost associated with ERAS. Further studies assessing QOL and cost-effectiveness over the entire global period of care in a variety of urologic oncology surgeries are warranted.

The impact of the social construct of race on outcomes among bacille Calmette-Guérin-treated patients with high-risk non-muscle-invasive bladder cancer in an equal-access setting.

BACKGROUND: The objective of this study was to describe bladder cancer outcomes as a function of race among patients with high-risk non-muscle-invasive bladder cancer (NMIBC) in an equal-access setting. METHODS: A total of 412 patients with high-risk NMIBC who received bacille Calmette-Guérin (BCG) from January 1, 2010, to December 31, 2015, were assessed. The authors used the Kaplan-Meier method to estimate event-free survival and Cox regression to determine the association between race and recurrence, progression, disease-specific, and overall survival outcomes. RESULTS: A total of 372 patients who had complete data were included in the analysis; 48 (13%) and 324 (87%) were Black and White, respectively. There was no difference in age, sex, smoking status, or Charlson Comorbidity Index by race. White patients had a higher socioeconomic status with a greater percentage of patients living above the poverty level in comparison with Black patients (median, 85% vs 77%; P < .001). A total of 360 patients (97%) received adequate induction BCG, and 145 patients (39%) received adequate maintenance BCG therapy. There was no significant difference in rates of adequate induction or maintenance BCG therapy according to race. There was no significant difference in recurrence (hazard ratio [HR], 1.53; 95% confidence interval [CI], 0.64-3.63), progression (HR, 0.77; 95% CI, 0.33-1.82), bladder cancer-specific survival (HR, 1.01; 95% CI, 0.30-3.46), or overall survival (HR, 0.97; 95% CI, 0.56-1.66) according to Black race versus White race. CONCLUSIONS: In this small study from an equal-access setting, there was no difference in the receipt of BCG or any differences in bladder cancer outcomes according to race.

Use of psychotropic drugs among older patients with bladder cancer in the United States.

OBJECTIVE: Older patients diagnosed with cancer are at increased risk of physical and emotional distress; however, prescription utilization patterns largely remain to be elucidated. Our objective was to comprehensively assess prescription patterns and predictors in older patients with bladder cancer. METHODS: A total of 10,516 older patients diagnosed with clinical stage T1-T4a, N0, M0 bladder urothelial carcinoma from 1 January 2008 to 31 December 2012 from the Surveillance, Epidemiology, and End Results (SEER)-Medicare were analyzed. We used multivariable analysis to determine predictors associated with psychotropic prescription rates (one or more). Medication possession ratio (MPR) was used as an index to measure adherence in intervals of 3 months, 6 months, 1 year, and 2 years. Evaluation of psychotropic prescribing patterns and adherence across different drugs and demographic factors was done. RESULTS: Of the 10,516 older patients, 5621 (53%) were prescribed psychotropic drugs following cancer diagnosis. Overall, 3972 (38%) patients had previous psychotropic prescriptions prior to cancer diagnosis, and these patients were much more likely to receive a post-cancer diagnosis prescription. Prescription rates for psychotropic medications were higher among patients with higher stage BC (p < 0.001). Gamma aminobutyric acid modulators/stimulators and serotonin reuptake inhibitors/stimulators were the highest prescribed psychotropic drugs in 21% of all patients. Adherence for all drugs was 32% at 3 months and continued to decrease over time. CONCLUSION: Over half of the patients received psychotropic prescriptions within 2 years of their cancer diagnosis. Given the chronicity of psychiatric disorders with observed significantly low adherence to medications that warrants an emphasis on prolonged patient monitoring and further investigation.

Intraoperative and early postoperative complications in postchemotherapy retroperitoneal lymphadenectomy among patients with germ cell tumors using validated grading classifications.

BACKGROUND: Postchemotherapy retroperitoneal lymphadenectomy (PC-RPLND) is an essential, yet potentially morbid, therapy for the management of patients with advanced germ cell tumors. In the current study, the authors sought to define the complication profile of PC-RPLND using validated grading systems for intraoperative adverse events (iAEs) and early postoperative complications. METHODS: Between 2000 and 2018, all patients who underwent PC-RPLND were analyzed for iAEs and early postoperative complications using the Kaafarani and Clavien-Dindo classifications, respectively. Logistic regression models were conducted to assess patient and tumor factors associated with iAEs and postoperative complications. RESULTS: Of the 453 patients identified, 115 patients (25%) and 252 patients (56%), respectively, experienced an iAE and postoperative complication. Major iAEs (grade ≥3) were observed in 15 patients (3%) and major postoperative complications (grade ≥3) were noted in 80 patients (18%). The most common iAE was vascular injury (112 of 132 events; 85%), which occurred in 92 patients (20%), and the most frequent postoperative complication was ileus, which occurred in 121 patients (27%). Original and postchemotherapy retroperitoneal mass size, nonretroperitoneal metastases, intermediate and/or poor International Germ Cell Cancer Collaborative Group classification, previous RPLND, elevated tumor markers at the time of RPLND, and anticipated adjuvant surgical procedures increased the risk of both iAEs and postoperative complications. Patients who experienced an iAE were significantly more likely to experience a postoperative complication (odds ratio, 2.50; 95% confidence interval, 1.58-3.97 [P < .001]). CONCLUSIONS: In what to the authors' knowledge is the first analysis of PC-RPLND using validated classifications for both iAEs and postoperative complications, advanced disease and surgical complexity significantly increased the risks of major iAEs and postoperative complications. Standardized reporting of adverse perioperative events allows providers and patients to appreciate the consequences of PC-RPLND during counseling and decision making.

DNA methylation patterns in bladder tumors of African American patients point to distinct alterations in xenobiotic metabolism.

Racial/ethnic disparities have a significant impact on bladder cancer outcomes with African American patients demonstrating inferior survival over European-American patients. We hypothesized that epigenetic difference in methylation of tumor DNA is an underlying cause of this survival health disparity. We analyzed bladder tumors from African American and European-American patients using reduced representation bisulfite sequencing (RRBS) to annotate differentially methylated DNA regions. Liquid chromatography-mass spectrometry (LC-MS/MS) based metabolomics and flux studies were performed to examine metabolic pathways that showed significant association to the discovered DNA methylation patterns. RRBS analysis showed frequent hypermethylated CpG islands in African American patients. Further analysis showed that these hypermethylated CpG islands in patients are commonly located in the promoter regions of xenobiotic enzymes that are involved in bladder cancer progression. On follow-up, LC-MS/MS revealed accumulation of glucuronic acid, S-adenosylhomocysteine, and a decrease in S-adenosylmethionine, corroborating findings from the RRBS and mRNA expression analysis indicating increased glucuronidation and methylation capacities in African American patients. Flux analysis experiments with 13C-labeled glucose in cultured African American bladder cancer cells confirmed these findings. Collectively, our studies revealed robust differences in methylation-related metabolism and expression of enzymes regulating xenobiotic metabolism in African American patients indicate that race/ethnic differences in tumor biology may exist in bladder cancer.

Predictors of skeletal-related events and mortality in men with metastatic, castration-resistant prostate cancer: Results from the Shared Equal Access Regional Cancer Hospital (SEARCH) database.

BACKGROUND: Although skeletal-related events (SREs) are linked with a reduced quality of life and worse outcomes, to the authors' knowledge the factors that predict SREs are minimally understood. The objective of the current study was to identify predictors of SREs and all-cause mortality among men with metastatic castration-resistant prostate cancer (mCRPC). METHODS: Data were collected on 837 men with bone mCRPC at 8 Veterans Affairs medical centers within the Shared Equal Access Regional Cancer Hospital (SEARCH) database from 2000 through 2017. Patients were followed to assess development of SREs (pathological fracture, radiotherapy to bone, spinal cord compression, or surgery to bone). Cox proportional hazards models were used to evaluate predictors of SREs and mortality. RESULTS: Of the 837 men with bone mCRPC, 287 developed a SRE and 740 men died (median follow-up, 26 months). Bone pain was found to be the strongest predictor of SREs (hazard ratio [HR], 2.96; 95% CI, 2.25-3.89). A shorter time from CRPC to the development of metastasis (HR, 0.92; 95% CI, 0.85-0.99), shorter progression to CRPC (HR, 0.94; 95% CI, 0.91-0.98), and visceral metastasis at the time of diagnosis of bone metastasis (HR, 1.91; 95% CI, 1.18-3.09) were associated with an increased risk of SREs. Ten or more bone metastases (HR, 2.17; 95% CI, 1.72-2.74), undergoing radical prostatectomy (HR, 0.73; 95% CI, 0.61-0.89), shorter progression to CRPC (HR, 0.97; 95% CI, 0.94-0.99), older age (HR, 1.03; 95% CI, 1.02-1.04), higher prostate-specific antigen level at the time of diagnosis of metastasis (HR, 1.21; 95% CI, 1.14-1.28), bone pain (HR, 1.44; 95% CI, 1.23-1.70), and visceral metastasis (HR, 1.72; 95% CI, 1.23-2.39) were associated with an increased mortality risk. CONCLUSIONS: Among men with bone mCRPC, bone pain was found to be the strongest predictor of SREs and the number of bone metastases was a strong predictor of mortality. If validated, these factors potentially may be used for risk stratification and for SRE prevention strategies.

Cancer diagnosis and risk of suicide after accounting for prediagnosis psychiatric care: A matched-cohort study of patients with incident solid-organ malignancies.

BACKGROUND: Previous studies have demonstrated an association between a diagnosis of cancer and the risk of suicide; however, they failed to account for psychiatric care before a cancer diagnosis, which may confound this relationship. The objective of this study was to assess the effect of a cancer diagnosis on the risk of suicide, accounting for prediagnosis psychiatric care utilization. METHODS: All adult residents of Ontario, Canada who were diagnosed with cancer (1 of prostate, breast, colorectal, melanoma, lung, bladder, endometrial, thyroid, kidney, or oral cancer) between 1997 and 2014 were identified. Noncancer controls were matched 4:1 based on sociodemographics, including a psychiatric utilization gradient (PUG) score (with 0 indicating none; 1, outpatient; 2, emergency department; and 3, hospital admission). A marginal, cause-specific hazard model was used to assess the effect of cancer on the risk of suicidal death. RESULTS: Among 676,470 patients with cancer and 2,152,682 matched noncancer controls, there were 8.2 and 11.4 suicides per 1000 person-years of follow-up, respectively. Patients with cancer had an overall higher risk of suicidal death compared with matched patients without cancer (hazard ratio, 1.34; 95% CI, 1.22-1.48). This effect was pronounced in the first 50 months after cancer diagnosis (hazard ratio, 1.60; 95% CI, 1.42-1.81); patients with cancer did not demonstrate an increased risk thereafter. Among individuals with a PUG score 0 or 1, those with cancer were significantly more likely to die of suicide compared with controls. There was no difference in suicide risk between patients with cancer and controls for those who had a PUG score of 2 or 3. CONCLUSIONS: A cancer diagnosis is associated with increased risk of death from suicide compared with the general population even after accounting for precancer diagnosis psychiatric care utilization. The specific factors underlying the observed associations remain to be elucidated.

The impact of psychiatric utilisation prior to cancer diagnosis on survival of solid organ malignancies.

BACKGROUND: Among patients with cancer, prior research suggests that patients with mental illness may have reduced survival. The objective was to assess the impact of psychiatric utilisation (PU) prior to cancer diagnosis on survival outcomes. METHODS: All residents of Ontario diagnosed with one of the top 10 malignancies (1997-2014) were included. The primary exposure was psychiatric utilisation gradient (PUG) score in 5 years prior to cancer: 0: none, 1: outpatient, 2: emergency department, 3: hospital admission. A multivariable, cause-specific hazard model was used to assess the effect of PUG score on cancer-specific mortality (CSM), and a Cox proportional hazard model for effect on all-cause mortality (ACM). RESULTS: A toal of 676,125 patients were included: 359,465 (53.2%) with PUG 0, 304,559 (45.0%) PUG 1, 7901 (1.2%) PUG 2, and 4200 (0.6%) PUG 3. Increasing PUG score was independently associated with worse CSM, with an effect gradient across the intensity of pre-diagnosis PU (vs PUG 0): PUG 1 h 1.05 (95% CI 1.04-1.06), PUG 2 h 1.36 (95% CI 1.30-1.42), and PUG 3 h 1.73 (95% CI 1.63-1.84). Increasing PUG score was also associated with worse ACM. CONCLUSIONS: Pre-cancer diagnosis PU is independently associated with worse CSM and ACM following diagnosis among patients with solid organ malignancies.

Perceptions of Barriers Towards Active Surveillance for Low-Risk Prostate Cancer: Results From a National Survey of Radiation Oncologists and Urologists.

PURPOSE: The reasons for low clinical adoption of active surveillance (AS) for low-risk prostate cancer (PCa) remain poorly understood. Thus, we conducted a national survey of radiation oncologists (ROs) and urologists (UROs) to elucidate perceived barriers to AS for low-risk PCa. METHODS: In 2017, we undertook a four-wave mail survey of 1855 ROs and UROs. The survey instrument assessed attitudes about possible barriers towards AS for low-risk PCa. We used Pearson Chi square and multivariable logistic regression analyses to identify physician characteristics associated with attitudes about AS. RESULTS: We received 691 completed surveys for an overall response rate of 37.3%. A majority of respondents indicated that they felt comfortable recommending AS (90.0%), agreed that high-level evidence supports it (82.3%), and considered AS equally effective for survival compared with surgery and radiation therapy (84.4%). UROs were less likely to agree that patients were not interested in AS for low-risk PCa compared with ROs (16.5 vs. 48.9%; adjusted odds ratio [OR] 0.18, p < 0.001). Similarly, UROs were less likely to concur patients avoid AS because of repeat prostate biopsies than ROs (36.3 vs. 55.4%; adjusted OR 0.41, p < 0.001). ROs and UROs were more likely to agree that patients preferred treatments delivered by the respondent's specialty. CONCLUSIONS: Physician perceptions of patient lack of interest in AS, need for repeat prostate biopsies, and biases of patient treatment preferences in favor of their own specialty treatments represent key barriers to AS. Shared decision making may be a meaningful approach to engaging patients in conversations about treatment decisions.

Association of the extent of therapy with prostate cancer in those receiving testosterone therapy in a US commercial insurance claims database.

BACKGROUND: Conflicting evidence remains in the association of testosterone therapy (TTh) with prostate cancer (PCa). This inconsistency maybe due, in part, to the small sample sizes from previous studies and an incomplete assessment of comorbidities, particularly diabetes. OBJECTIVE: We investigated the association of PCa with TTh (injection or gel) and different TTh doses and determined whether this association varies by the presence of diabetes at baseline in a large, nationally representative, commercially insured cohort. DESIGN: We conducted a retrospective cohort study of 189 491 men aged 40-60 years old in the IBM MarketScan® Commercial Database, which included 1424 PCa cases diagnosed from 2011 to 2014. TTh was defined using CPT codes from inpatient and outpatient, and NDC codes from pharmacy claims. Multivariable adjusted Cox proportional hazards models were used to compute hazard ratios for patients with incident PCa. RESULTS: We found a 33% reduced association of PCa after comparing the highest category (>12) of TTh injections with the lowest (1-2 injections) category (HR = 0.67, 95% CI: 0.54-0.82). Similar statistical significant inverse association for PCa was observed for men who received TTh topical gels (>330 vs 1- to 60-days supply). Among nondiabetics, we found significant inverse association between TTh (injection and gel) and PCa, but a weak interaction between TTh injections and diabetes (P = .05). CONCLUSION: Overall, increased use of TTh is inversely associated with PCa and this remained significant only among nondiabetics. These findings warrant further investigation in large randomized placebo-controlled trials to infer any health benefit by TTh.

Radical prostatectomy or radiotherapy for high- and very high-risk prostate cancer: a multidisciplinary prostate cancer clinic experience of patients eligible for either treatment.

OBJECTIVE: To compare radical prostatectomy (RP) vs radiotherapy (RT) with androgen-deprivation therapy (ADT) in the setting of patients with high-risk and very high-risk (VHR) prostate cancer who were deemed eligible for either therapy and made a treatment choice after consultation in a multidisciplinary prostate cancer clinic (MDPCC), and to compare the MDPCC patients' outcomes to a matched Surveillance, Epidemiology and End Results (SEER) cohort. PATIENTS AND METHODS: Prospectively collected, retrospective study comparing patients who underwent RP (231 patients) vs RT+ADT (73) from 2004 to 2013. Biochemical recurrence (BCR), local recurrence, distant metastasis failure, and overall survival (OS) were calculated for each treatment group overall and according to National Comprehensive Cancer Network risk strata. A propensity score matched comparison with a SEER cohort was performed for OS. RESULTS: There was no difference in local recurrence (hazard ratio [HR] 2.7, 95% confidence interval [CI] 1.0-7.9; P = 0.06), distant metastasis failure (HR 2.5, 95% CI 0.8-7.8; P = 0.1) and OS (HR 1.35, 95% CI 0.4-4.8; P = 0.6) between patients undergoing RP vs RT+ADT. Patients treated via the MDPCC survived on average 16.9 months (95% CI 13.1-20.8) longer than those in the matched SEER cohort. CONCLUSIONS: Long-term outcomes appear similar amongst patients with high-risk and VHR prostate cancer deemed eligible for either RP or RT, and treated after consultation in a MDPCC. Outcomes of the MDPCC patients were superior to those of the matched SEER cohort.

Focal Laser Ablation of Prostate Cancer: Results in 120 Patients with Low- to Intermediate-Risk Disease.

PURPOSE: Can focal laser ablation (FLA) of low to intermediate risk prostate cancer preserve sexual and urinary function with low morbidity while providing adequate oncologic outcomes. MATERIALS AND METHODS: Transrectal FLA was done in 120 patients with low- to intermediate-risk prostate cancer. MR imaging thermometry controlled ablation. At 6 and 12 months, patients had clinical and MR imaging follow-up with biopsy of suspicious areas. Patients submitted surveys of sexual and urinary function. Multivariate logistic regression identified determinants of positive imaging and biopsies. Two-sided Wilcoxon signed rank test evaluated scores and laboratory values. RESULTS: Median patient age was 64 years, and median prostate-specific antigen (PSA) was 6.05 ng/mL. Median follow-up period was 34 months (range, 17-55 months). Gleason score was 3+3=6 in 37 (30.8%), 3+4=7 in 56 (46.7%), and 4+3=7 in 27 (22.5%) patients. Tumor stage was T1c in 89 (74.2%), T2a in 26 (21.7%), and T2b in 5 (4.2%) patients. Twenty (17%) patients had additional oncologic therapy 1 year after FLA when biopsy confirmed cancer following abnormal MR imaging. There was no difference between functional scores before and after ablation. Median PSA decreased to 3.25 at 12 months (P < .001). Tumor diameter above the median (odds ratio = 3.36; 95% confidence interval, 1.41-7.97) was the only significant predictor for positive MR imaging after treatment. CONCLUSIONS: One year after FLA, selected patients had low morbidity, no significant changes in quality of life, and 83% freedom of retreatment rate. Sexual and urinary function did not significantly change after FLA.

Biochemical recurrence after radical prostatectomy: Current status of its use as a treatment endpoint and early management strategies.

Prostate cancer is one of the most common urological malignancies managed by a practicing urologist. Treatment strategies are varied, but radical prostatectomy (RP) remains a viable and commonly used option for many patients. A continuing challenge in the management is how to approach a patient who has biochemical recurrence (BCR) after RP. There are no consensus guidelines on the appropriate strategy, and the current recommendations, although useful, are at times confusing. The natural history of BCR is heterogeneous. Published studies aid in the clinician's ability to predict patients most likely to recur; however, this remains inexact. In addition, recent changes in the recommendations for disease screening, as well as technological advances, have added to the already challenging task of the clinician. The objective of this review is to provide an up-to-date summary of the definitions, diagnosis, and management strategies of BCR after RP. This narrative review was conducted by searching Medline for all relevant articles in English with the key terms of biochemical recurrence, prostate cancer, management, and other relevant terms. Information was compiled and reviewed for relevance to the article. Consideration was given to all articles with sufficient evidence including systematic review, retrospective studies, and clinical trials.

Adapting the Elixhauser comorbidity index for cancer patients.

BACKGROUND: This study was designed to adapt the Elixhauser comorbidity index for 4 cancer-specific populations (breast, prostate, lung, and colorectal) and compare 3 versions of the Elixhauser comorbidity score (individual comorbidities, summary comorbidity score, and cancer-specific summary comorbidity score) with 3 versions of the Charlson comorbidity score for predicting 2-year survival with 4 types of cancer. METHODS: This cohort study used Texas Cancer Registry-linked Medicare data from 2005 to 2011 for older patients diagnosed with breast (n = 19,082), prostate (n = 23,044), lung (n = 26,047), or colorectal cancer (n = 16,693). For each cancer cohort, the data were split into training and validation cohorts. In the training cohort, competing risk regression was used to model the association of Elixhauser comorbidities with 2-year noncancer mortality, and cancer-specific weights were derived for each comorbidity. In the validation cohort, competing risk regression was used to compare 3 versions of the Elixhauser comorbidity score with 3 versions of the Charlson comorbidity score. Model performance was evaluated with c statistics. RESULTS: The 2-year noncancer mortality rates were 14.5% (lung cancer), 11.5% (colorectal cancer), 5.7% (breast cancer), and 4.1% (prostate cancer). Cancer-specific Elixhauser comorbidity scores (c = 0.773 for breast cancer, c = 0.772 for prostate cancer, c = 0.579 for lung cancer, and c = 0.680 for colorectal cancer) performed slightly better than cancer-specific Charlson comorbidity scores (ie, the National Cancer Institute combined index; c = 0.762 for breast cancer, c = 0.767 for prostate cancer, c = 0.578 for lung cancer, and c = 0.674 for colorectal cancer). Individual Elixhauser comorbidities performed best (c = 0.779 for breast cancer, c = 0.783 for prostate cancer, c = 0.587 for lung cancer, and c = 0.687 for colorectal cancer). CONCLUSIONS: The cancer-specific Elixhauser comorbidity score performed as well as or slightly better than the cancer-specific Charlson comorbidity score in predicting 2-year survival. If the sample size permits, using individual Elixhauser comorbidities may be the best way to control for confounding in cancer outcomes research.

Impact of psychiatric illness on decreased survival in elderly patients with bladder cancer in the United States.

BACKGROUND: Treatments for muscle-invasive bladder cancer are multimodal, complex, and often carry significant risks of physical and psychological morbidity. The objectives of this study were to define the incidence and types of psychiatric illnesses diagnosed after treatment and to determine their impact on survival outcomes. METHODS: In total, 3709 patients who were diagnosed with clinical stage T2 through T4a bladder cancer from January 1, 2002, to December 31, 2011, from the Surveillance, Epidemiology, and End Results-Medicare were analyzed. Multivariable analysis and Cox proportional-hazards models were used to determine the predictors associated with psychiatric diagnosis and impact on survival outcomes. RESULTS: Of 3709 patients, 1870 (50.4%) were diagnosed with posttreatment psychiatric disorders. Patients who underwent radical cystectomy were identified as being at significantly greater risk of having a posttreatment psychiatric illness compared with those who received radiotherapy and/or chemotherapy (hazard ratio [HR], 1.19; 95% confidence interval [CI], 1.07-1.31; P = .001). In adjusted analyses, diagnosis of a psychiatric disorder resulted in significantly worse overall survival (HR, 2.80; 95% CI, 2.47-3.17; P < .001) and cancer-specific survival (HR, 2.39; 95% CI, 2.05-2.78; P < .001). CONCLUSIONS: One-half of patients with muscle-invasive bladder cancer who underwent treatment were diagnosed with a psychiatric disorder, which resulted in worse survival outcomes compared with patients who did not have a posttreatment psychiatric diagnosis. This information can be used to inform interventions to educate patients with muscle-invasive bladder cancer regarding the impact of different treatments on mental health.

Initial series of magnetic resonance imaging (MRI)-fusion targeted prostate biopsy using the first transperineal targeted platform available in the USA.

OBJECTIVES: To describe a step-by-step guide for using the first transperineal targeted prostate biopsy platform available in the USA. PATIENTS AND METHODS: A total of 32 men with elevated prostate-specific antigen (PSA) levels were diagnosed with a region of interest on multiparametric magnetic resonance imaging (mpMRI) between February 2017 and January 2018. The transperineal targeted prostate biopsy procedure was accomplished via a transperineal approach and used a stepper, combined with advanced mpMRI/transrectal ultrasound fusion software, to perform targeted prostate biopsy. The detection of overall and clinically significant prostate cancer (PCa) was assessed as well as the rate of complications. RESULTS: The median patient age was 68.0 years and the median PSA was 8.0 ng/mL. Two patients (6%) were active surveillance candidates and 16 (50%) had a prior negative prostate biopsy. The detection rates for overall and clinically significant PCa were 81% and 59%, respectively. The two candidates for active surveillance and eight of the patients with a prior negative prostate biopsy had clinically significant PCa confirmed on targeted biopsy. There were no peri-operative complications. CONCLUSION: These results demonstrate the promising potential of the first transperineal targeted prostate biopsy platform in the USA as an alternative diagnostic method for PCa.

Survival and secondary interventions following treatment for locally-advanced prostate cancer.

INTRODUCTION: The utility of radical prostatectomy (RP) for locally-advanced prostate cancer remains unknown. Retrospective data has shown equivalent oncologic outcomes compared to radiation therapy (RT). RP may provide local tumor control and prevent secondary interventions from local invasion, and may decrease costs. MATERIALS AND METHODS: Using SEER-Medicare data from 1995-2011 we identified men with locally-advanced prostate cancer undergoing RP or RT. Rates of post-treatment diagnoses and interventions were identified using ICD-9 and CPT codes. Skeletal related events (SRE), androgen deprivation therapy (ADT) utilization, all-cause mortality, prostate cancer-specific mortality, and costs were compared. RESULTS: A total of 8367 men with locally-advanced prostate cancer were identified (6200 RP, 2167 RT). RT was associated with increased urinary obstruction, hematuria, infection, and cystoscopic intervention while RP was associated with increased urethral stricture intervention and erectile dysfunction. Compared to RT, RP was associated with decreased all-cause mortality (3.1 versus 5.2 deaths/100-person-years, p < 0.001), prostate cancer-specific mortality (0.8 versus 2.0 deaths/100-person-years, p < 0.001), SREs (2.0 versus 3.4 events/100 person-years, p < 0.001), and ADT utilization overall (7.4 versus 33.8 doses/100-person-years, p < 0.001) and > 3 years after treatment (3.6 versus 4.6 doses/100-person-years, p < 0.001). Overall and cancer specific costs were significantly lower for RP versus RT. CONCLUSIONS: RT for locally-advanced prostate cancer has a higher incidence of mortality, secondary diagnoses and interventions, SRE, and ADT utilization compared to RP. This may lead to increased costs and have implications for quality of life. Our findings support the utility of RP in appropriately selected men with locally-advanced prostate cancer given the possible decreased morbidity and survival benefit.
