RESUMO

Robotic surgery has shown to have numerous benefits over traditional and laparoscopic surgery, namely, superior precision and improved recovery with shorter hospital stays. However, robotic surgery also presents several issues, including hemodynamic changes related to positioning and the use of pneumoperitoneum. These matters can be problematic in patients with neuromuscular conditions such as Friedreich ataxia (FRDA). Due to a baseline weakened musculature and a higher prevalence of cardiac disease and scoliosis, patients with FRDA may not be as likely to tolerate the cardiopulmonary physiologic changes associated with robotic surgery. Additionally, positioning for robotic surgery can be challenging in FRDA patients who have progressed to spasticity and contractures. To the best of our knowledge, there are no case reports of approaches specifically discussing anesthesia management for robotic surgery in the FRDA patient population. Anesthesia in general must be carefully planned in FRDA patients to allow for the best possible recovery and minimize complications. Due to the underlying neuromuscular compromise seen in these patients, their ability to recover from the pharmacologic and physiologic changes associated with anesthesia can be more difficult. They are prone to sensitivity to opioids, sedatives, and neuromuscular blocking agents (NMBAs) and are less likely to tolerate hemodynamic changes. Our review revealed no literature to suggest the routine use of Enhanced Recovery After Surgery (ERAS) protocols in FRDA patients or in patients with neuromuscular disease in general. The use of sugammadex has also been shown to be safe, and literature suggests superiority in both the general population and those with neuromuscular conditions. Our understanding is that there is very limited literature in regard to the safe use of sugammadex in FRDA patients.

RESUMO

OBJECTIVE: To investigate the association of female sex with the selected treatment for patients with nonmetastatic muscle-invasive bladder cancer. Sex is a known independent predictor of death from bladder cancer. A potential explanation for this survival disparity is difference in treatment pattern and stage presentation among males and females. MATERIALS AND METHODS: Using the surveillance, epidemiology, and end results-medicare data set, we identified 6809 patients initially diagnosed with nonmetastatic muscle-invasive bladder cancer between 2004 and 2014. We fit multivariable logistic regression and Cox models to assess the relationship of sex with treatment modality and survival adjusting for differences in patient characteristics. RESULTS: Of the 6809 patients with nonmetastatic muscle invasive bladder cancer, 2528 (37%) received a radical cystectomy while 4281 (63%) received an alternative bladder sparing intervention. Women were significantly more likely to receive a cystectomy (odds ratios [OR] 1.39; 95% confidence intervals [CI] 1.20-1.61), present at an older age with less comorbidities compared to men (P <.001). Women were also found to have worse bladder cancer-specific survival (CSS) than men (hazard ratio [HR] 1.18; 95% CI 1.05-1.32), no difference in overall survival (OS) (female HR 0.93; 0.86-1.01) and lower mortality from other causes (HR 0.78; 95% CI 0.70-0.86). There were no differences in OS and CSS by sex in patients with stage pT4a. CONCLUSION: Female sex predicted more aggressive treatment with radical cystectomy yet worse cancer-specific survival than males. This sex disparity in CSS reduced the known OS advantage observed in women.

RESUMO

BACKGROUND: We use observational methods to compare impact of perioperative chemotherapy timing (ie, neoadjuvant and adjuvant) on overall survival (OS) in muscle-invasive bladder cancer because there is no head-to-head randomized trial, and patient factors may influence decision-making. PATIENTS AND METHODS: Using Surveillance, Epidemiology, and End Results-Medicare data, we identified patients receiving cystectomy for muscle-invasive bladder cancer diagnosed between 2004 and 2013. Patients were classified as receiving neoadjuvant or adjuvant chemotherapy. Propensity of receiving neoadjuvant chemotherapy was determined using gradient boosted models. Inverse probability of treatment weighted survival curves were adjusted for 13 demographic, socioeconomic, temporal, and oncologic covariates. RESULTS: We identified 1342 patients who received neoadjuvant (n = 676) or adjuvant chemotherapy (n = 666) with a median follow-up of 23 months (interquartile range, 9-55 months). Inverse probability of treatment weighted adjustment allows comparison of the groups head-to-head as well as counterfactual scenarios (eg, effect if those getting one treatment were to receive the other). The average treatment effect (ie, "head-to-head" comparison) of adjuvant compared with neoadjuvant on OS was not significant (hazard ratio, 1.14; 95% confidence interval, 0.99-1.31). However, the average treatment effect of the treated (ie, the effect if the neoadjuvant patients were to receive adjuvant instead) was associated with a 33% increase in risk of mortality if they were given adjuvant therapy instead (hazard ratio, 1.33; 95% confidence interval, 1.12-1.57). CONCLUSION: Significant treatment selection bias was noted in peri-cystectomy timing, which limits the ability to discriminate differential efficacy of these 2 approaches with observational data. However, patients with higher propensity to receive neoadjuvant therapy were predicted to have increased OS with approach, in keeping with existing paradigms from trial data.

RESUMO

BACKGROUND: Multiparametric magnetic resonance imaging (mpMRI) may improve prostate cancer risk stratification and decrease the need for repeat biopsies in men on prostate cancer active surveillance (AS). However, the impact of mpMRI on AS-related healthcare spending has not been established. OBJECTIVE: To characterize the impact of mpMRI on AS-related Medicare expenditures. DESIGN, SETTING, AND PARTICIPANTS: Using Surveillance, Epidemiology, and End Results (SEER)-Medicare files, we identified men ≥66 yr old with localized prostate cancer diagnosed during 2008-2013. OUTCOME MEASURES AND STATISTICAL ANALYSIS: With a validated algorithm, we classified men into AS with and without mpMRI groups. We then determined Medicare spending on AS in each group using inflation-adjusted, price-standardized Medicare payments for AS-related procedures (ie, prostate-specific antigen [PSA] tests, prostate biopsies, biopsy complications, and mpMRI). Multivariable median regression compared Medicare spending on AS for men who received mpMRI and those who did not. RESULTS AND LIMITATIONS: We identified 9081 men on AS with a median follow-up of 45 mo (interquartile range 29-64 mo). Thirteen percent (N = 1225) received mpMRI. On multivariable median regression, receipt of mpMRI was associated with an additional $447 (95% confidence interval $409-487) in Medicare spending per year. We observed greater frequency of AS-related procedures and higher spending for identical procedures (eg, PSA or prostate biopsy) in the mpMRI group than in the non-mpMRI group (all p < 0.001). CONCLUSIONS: Among Medicare beneficiaries on AS, mpMRI is associated with additional annual Medicare spending. Future studies are needed to determine optimal use of mpMRI during AS to maximize value. PATIENT SUMMARY: Prostate magnetic resonance imaging (MRI) helps physicians determine which prostate cancers are aggressive and which can be monitored safely. We studied whether using MRI during prostate cancer monitoring (also called active surveillance) resulted in increased healthcare spending. There was a modest increase in spending, but this may be worthwhile if the use of MRI allows physicians to monitor prostate cancer more accurately.

RESUMO

OBJECTIVE: To examine long- and short-term outcomes using cell salvage with a commercially available leukocyte depletion filter following radical cystectomy in an oncologic population. MATERIALS AND METHODS: One hundred and fifty-seven patients, 87 of whom received a cell salvage transfusion, were retrospectively identified from chart review. Ninety-day outcomes as well as long-term mortality and cancer recurrence data were collected. Chi-square, Student's t, or Mann-Whitney U tests were used as appropriate. Multivariable regressions of survival were performed with a Cox proportional-hazards model. RESULTS: Those who received a cell salvage transfusion did not show any differences in rate of cancer recurrence (23%) vs those who did not receive a cell salvage transfusion (24%; P = .85). There were also no differences noted in mortality rates between the 2 populations (12% vs 17%; P = .36). Furthermore, no differences were noted in postoperative complication rates, length of hospital stay, 90-day culture positive infections or readmissions (P >.05). CONCLUSION: There are no significant differences in short-term or long-term patient outcomes between those who did and did not receive an intraoperative cell salvage transfusion. Cell salvage transfusions with a leukocyte depletion filter are safe and effective methods to reduce the need for allogeneic blood transfusions while controlling for the theoretical risk of metastatic spread.

RESUMO

BACKGROUND: Regionalization of complex surgical care results in increasing need for patients to travel for complex oncologic procedures such as cystectomy in bladder cancer. We examined the association between travel distance to a cystectomy center, readmission, and survival. PATIENTS AND METHODS: Using Surveillance, Epidemiology, and End Results (SEER)-Medicare data, we identified bladder cancer patients undergoing radical cystectomy during 2004-2011. Patients were grouped into quartiles of distance to cystectomy center in miles (< 6 [close], 6-16.9 [moderately close], 17-47.9 [moderately far], ≥ 48 [far]). Multivariable logistic regression, accounting for clustering within hospitals, was used to assess the association between travel distance and readmission. A secondary analysis examined the association between travel distance and survival using multivariable proportional hazard regression. RESULTS: Among 4556 patients who underwent cystectomy, 1857 (41%) were readmitted, and 1251 (67%) of readmissions were to the index hospital. With increasing travel distance there was no significant difference in the overall rate of 90-day readmission. However, the farther a patient traveled, the lower the odds of being readmitted to the index hospital (adjusted odds ratio [95% confidence interval] as follows: moderately close, 0.43 miles [0.29-0.63]; moderately far, 0.14 miles [0.10-0.19]; and far, 0.07 [0.05-0.11]). Increasing travel distance was associated with improved survival. CONCLUSION: With greater distance traveled to a cystectomy center, rates of readmission to nonindex centers increased. Survival differences may be explained by the impact of travel burden on processes of care and case mix. Future efforts should focus on improving care coordination between index and nonindex hospitals and ensuring equitable access to cystectomy and other critical cancer services.

RESUMO

INTRODUCTION: Contemporary guidelines recommend cystectomy with neoadjuvant or adjuvant cisplatin-based chemotherapy given with curative intent for patients with resectable muscle-invasive bladder cancer (MIBC). However, rates and appropriateness of perioperative chemotherapy utilization remain unclear. We therefore sought to characterize use of perioperative chemotherapy in older radical cystectomy MIBC patients and examine factors associated with use. METHODS: Using Surveillance, Epidemiology, and End Results (SEER)-Medicare data, we identified patients with MIBC diagnosed between 2004 and 2013 and treated with radical cystectomy. We classified patients into 3 treatment groups: cystectomy alone, neoadjuvant, or adjuvant chemotherapy. Chemotherapy was classified by regimen. We then fit a multinomial multivariable logistic regression model to assess association between patient factors with the receipt of each treatment. RESULTS: We identified 3,826 eligible patients. The majority (484; 65%) received cystectomy alone. Neoadjuvant (676; 18% overall, 69% cisplatin-based), and adjuvant chemotherapy (666, 17% overall, 55% cisplatin-based) were used in similar proportions of cystectomy patients. Over the study period, the odds of receiving adjuvant chemotherapy decreased by 7.5%, whereas neoadjuvant therapy increased by 27.5% (both P < 0.001). There was an increase in use of cisplatin-based regimens in the neoadjuvant setting (35 to 72%, P < 0.001), but not the adjuvant setting. Female gender, lower comorbidity, married status, and lower stage disease were associated with greater odds of receiving neoadjuvant chemotherapy (all P < 0.05). CONCLUSION: From 2004 to 2013 use of neoadjuvant chemotherapy for MIBC increased while use of adjuvant chemotherapy decreased. Future studies examining barriers to appropriate chemotherapy use, and the comparative effectiveness of neoadjuvant versus adjuvant chemotherapy are warranted.

RESUMO

OBJECTIVE: To characterize the use of multiparametric magnetic resonance imaging (mpMRI) in male Medicare beneficiaries electing active surveillance for prostate cancer. mpMRI has emerged as a tool that may improve risk-stratification and decrease repeated biopsies in men electing active surveillance. However, the extent to which mpMRI has been implemented in active surveillance has not been established. METHODS: Using Surveillance, Epidemiology, and End Results registry data linked to Medicare claims data, we identified men with localized prostate cancer diagnosed between 2008 and 2013 and managed with active surveillance. We classified men into 2 treatment groups: active surveillance without mpMRI and active surveillance with mpMRI. We then fit a multivariable logistic regression models to examine changing mpMRI utilization over time, and factors associated with the receipt of mpMRI. RESULTS: We identified 9467 men on active surveillance. Of these, 8178 (86%) did not receive mpMRI and 1289 (14%) received mpMRI. The likelihood of receiving mpMRI over the entire study period increased by 3.7% (P = .004). On multivariable logistic regression, patients who were younger, white, had lower comorbidity burden, lived in the northeast and west, had higher incomes and lived in more urban areas had greater odds of receiving mpMRI (all P < .05). CONCLUSION: From 2008 to 2013, use of mpMRI in active surveillance increased gradually but significantly. Receipt of mpMRI among men on surveillance for prostate cancer varied significantly across demographic, geographic, and socioeconomic strata. Going forward, studies should investigate causes for this variation and define ideal strategies for equitable, cost-effective dissemination of mpMRI technology.

RESUMO

OBJECTIVES: To describe the rate and determinants of palliative care use amongst Medicare beneficiaries with bladder cancer and encourage a national dialogue on improving coordinated urological, oncological, and palliative care in patients with genitourinary malignancies. PATIENTS AND METHODS: Using Surveillance, Epidemiology, and End Results-Medicare data, we identified patients diagnosed with muscle-invasive bladder cancer (MIBC) between 2008 and 2013. Our primary outcome was receipt of palliative care, defined as the presence of a claim submitted by a Hospice and Palliative Medicine subspecialist. We examined determinants of palliative care use using logistic regression analysis. RESULTS: Over the study period, 7303 patients were diagnosed with MIBC and 262 (3.6%) received palliative care. Of 2185 patients with advanced bladder cancer, defined as either T4, N+ , or M+ disease, 90 (4.1%) received palliative care. Most patients that received palliative care (>80%, >210/262) did so within 24 months of diagnosis. On multivariable analysis, patients receiving palliative care were more likely to be younger, female, have greater comorbidity, live in the central USA, and have undergone radical cystectomy as opposed to a bladder-sparing approach. The adjusted probability of receiving palliative care did not significantly change over time. CONCLUSIONS: Palliative care provides a host of benefits for patients with cancer, including improved spirituality, decrease in disease-specific symptoms, and better functional status. However, despite strong evidence for incorporating palliative care into standard oncological care, use in patients with bladder cancer is low at 4%. This study provides a conservative baseline estimate of current palliative care use and should serve as a foundation to further investigate physician-, patient-, and system-level barriers to this care.

RESUMO

OBJECTIVE: To determine the rate and determinants of neoadjuvant chemotherapy noncompletion in patients with muscle-invasive bladder cancer. METHODS: Using Surveillance, Epidemiology, and End Results-Medicare data, we identified all patients who underwent cystectomy between 2008-2013 and received chemotherapy within 6 months. Of these, 594 patients received neoadjuvant chemotherapy, defined as the presence of a claim for chemotherapy within the 180 days preceding cystectomy. Our primary outcome was noncompletion of neoadjuvant chemotherapy. We determined regimen-specific cut points for noncompletion based on clinical trials and national guidelines. RESULTS: Over the study period, 174 of 594 patients (29%) did not complete neoadjuvant chemotherapy. Noncompleters and completers received a median interquartile range of 4.4 (3.0-8.0) and 10.0 (7.7-11.2) weeks of chemotherapy, respectively. A total of 391 (66%) patients received a cisplatin-based regimen and 203 (34%) patients received an alternative regimen, with 27% and 33% not completing chemotherapy, respectively. After adjusting for covariates, age and geographic region were independently associated with failing to complete chemotherapy. CONCLUSION: Nearly 30% of patients who received neoadjuvant chemotherapy did not complete their regimen. Advanced age and nonclinical factors, such as practice patterns in certain geographic regions, may influence a patient's likelihood of successfully completing chemotherapy.

RESUMO

Over the last ten years, active surveillance (AS) has become increasingly utilized for patients with low-risk prostate cancer. Appropriately selected AS patients have a 10-year prostate cancer-specific mortality (PCSM) approaching 99%. Therefore, some institutions have expanded the inclusion criteria for AS to avoid the unnecessary morbidity associated with overtreatment. In this review, data from several high-quality studies were compiled to demonstrate how AS inclusion criteria may be safely expanded. Although AS criteria, data reporting, and statistical methods were heterogeneous across studies, several findings were consistent and provided insight for clinical practice. Gleason score ≥3+4 and prostate specific antigen density (PSAd) ≥0.15 ng/mL were consistently associated poor oncologic outcomes [biopsy reclassification/progression, adverse pathology at prostatectomy, biochemical recurrence (BCR), and PCSM]. Maximum single-core involvement, number of positive cores, and clinical stage were not consistently associated with negative outcomes. These data support the safety of expanded AS inclusion criteria beyond Epstein's very low-risk (VLR) criteria to include patients with clinical stage T2, up to 60% maximum core involvement, and up to 4 positive cores (Gleason 3+3 and ≤ PSAd 0.15 ng/mL). Furthermore, although it is clear that patients with intermediate-risk disease have poorer oncologic outcomes compared to low-risk, the absolute 10-year PCSM remains low and select patients may be optimally managed with AS. Although AS utilization is increasing, many men who might be safely managed with AS are still undergoing morbid and unnecessary definitive treatments. Further research into clinical parameters such as multiparametric magnetic resonance imaging (mpMRI) and genetic testing is required to improve the accuracy of patient stratification.

RESUMO

INTRODUCTION: Multimodal analgesia is an effective way to control pain and limit opioid use after surgery. The quadratus lumborum block and paravertebral block are two regional anesthesia techniques that leverage multimodal analgesia to improve postoperative pain control. We sought to compare the efficacy of these blocks for pain management following radical cystectomy. MATERIALS AND METHODS: We performed a retrospective review of radical cystectomy patients who received bilateral continuous paravertebral blocks (n = 125) or bilateral single shot quadratus lumborum blocks (n = 50) between 2014-2016. The primary outcome was postoperative opiate consumption on day 0. Secondary outcomes included self-reported pain scores and hospital length of stay. RESULTS: Quadratus lumborum block patients had similar opioid use on postoperative day 0 compared with paravertebral block patients (29 mg versus 30 mg, p = 0.90). Pain scores on postoperative day 0 were similar between quadratus lumborum block and paravertebral block groups (4.0 versus 3.8, p = 0.72); however, the paravertebral block group had lower pain scores on days 1-3 compared with the quadratus lumborum block group (all p < 0.05). Hospital length of stay was similar between groups (6.6 days versus 6.2 days, p = 0.41). CONCLUSIONS: There were no differences in opioid consumption among patients receiving bilateral single shot quadratus lumborum blocks and bilateral continuous paravertebral blocks after radical cystectomy. These data suggest that the quadratus lumborum block is a viable alternative for delivering multimodal analgesia in cystectomy patients.

RESUMO

Agent Orange is an herbicide sprayed widely in Vietnam that is linked to a variety of malignancies in as early as 1991.Since then, there has been concern for, and subsequent interest in studying, the potential connection between Agent Orange and other malignancies. In the past 2 decades, there have been significant changes in the opinion of the National Academy of Science regarding Agent Orange and certain genitourinary malignancies. Herein, we review the literature regarding the potential link between Agent Orange and various urological cancers, including prostate, bladder, testicular, and renal cancers.

RESUMO

PURPOSE: After the creation of a neourethra in a "hypospadias cripple," resurfacing the penis with healthy skin is a significant challenge because local tissue is often scarred and unusable. We reviewed our experience with various strategies to resurface the penis of hypospadias cripples. MATERIALS AND METHODS: We retrospectively reviewed the records of 215 patients referred after multiple unsuccessful hypospadias repairs from 1981 to 2014. In 130 of 215 patients we performed resurfacing using local penile flaps using various techniques, including Byars flaps, Z-plasty or double Z-plasty, or a dorsal relaxing incision. Of the 215 patients 85 did not have adequate healthy local penile skin to resurface the penis after urethroplasty. Scrotal skin was used to resurface the penis in 54 patients, 6 underwent tissue expansion of the dorsal penile skin during a 12 to 16-week period prior to penile resurfacing, 23 underwent full-thickness skin grafting and another 4 received a split-thickness skin graft. RESULTS: Of the 56 patients who underwent fasciomyocutaneous rotational flaps, tissue expansion or a combination of both approaches 54 (96.4%) finally had a successful outcome. All 6 patients who underwent tissue expansion had a successful outcome without complications and were reported on previously. All 23 full-thickness skin grafts took with excellent results. All 4 patients who underwent fenestrated split-thickness skin grafting had 100% graft take but secondary contraction and ulceration were associated with sexual activity. CONCLUSIONS: In our experience scrotal skin flaps, tissue expansion of the dorsal penile skin and full-thickness skin grafts serve as reliable approaches in resurfacing the penis in almost any hypospadias cripple lacking healthy local skin.

BACKGROUND: Studies show that enterocystoplasty has a negative effect on bone mineral density (BMD). The aim of this study was to investigate the long-term impact of enterocystoplasty on BMD. We used dual energy x-ray absorptiometry (DEXA) scans to determine BMD and identify patients with osteopenia and osteoporosis who are at potential long-term risk for fracture. MATERIALS AND METHODS: We reviewed our database of >200 individuals, who had undergone enterocystoplasty or continent diversion for both neurogenic and non-neurogenic reasons during childhood. We chose to study the non-neurogenic group first for a number of technical reasons, and identified 24 individuals who had undergone the procedure for non-neurogenic reasons, and had more than 15 years of follow-up. In addition we had a control group of 10 individuals born with bladder exstrophy, who had undergone primary closure before the year 2000, without enterocystoplasty. We used DEXA scan T- and Z-scores to identify patients with osteopenia and osteoporosis. RESULTS: Eleven of 24 patients had normal DEXA scans with normal T- and Z-scores; seven had identifiable osteopenia and increased long-term risk for fracture. Six had osteoporosis; three of whom had reduced glomerular filtration rate (GFR). Eight of the 10 individuals in the control group had a normal DEXA scan. CONCLUSIONS: Enterocystoplasty during childhood can lead to loss of BMD. This does not seem to be related to the enterocystoplasty alone. It is more pronounced in individuals who have other risk factors, such as reduced GFR. The identification of BMD loss makes it possible to intervene before osteoporosis occurs and leads to pathologic fracture.
