RESUMO

OBJECTIVE: To characterize changes in body composition following cytotoxic chemotherapy for germ cell carcinoma of the testis (GCT) and quantify associations between body composition metrics and chemotherapy-associated adverse events (AEs) and post-retroperitoneal lymph node dissection (RPLND) complications. MATERIALS AND METHODS: This retrospective multi-center study included 216 men with GCT treated with cytotoxic chemotherapy and/or RPLND (2005-2020). We measured body composition including skeletal muscle (SMI), visceral adipose (VAI,), subcutaneous adipose (SAI), and fat mass (FMI) indices on computed tomography. We quantified chemotherapy-associated changes in body composition and evaluated associations between body composition and incidence of grade 3 + AEs and post-RPLND complications on multivariable logistic regression analyses. RESULTS: One hundred and eighty-two men received a median of 3 cycles of cisplatin-based chemotherapy. Following chemotherapy, median change in SMI was -6% (P = <.0001), while VAI, SAI, and FMI increased by +13% (P = <.0001), +11% (P = <.0001), and +6% (P = <.0001), respectively. Seventy-nine patients (43%) experienced at least one grade 3 + AE. A decrease in SMI following chemotherapy was associated with increased risk of grade 3 + AEs (P = .047). One hundred and 3 men with a median age of 28.5 years (IQR 23-35.5) underwent RPLND of whom 22 (21.3%) experienced at least 1 grade 3 + post-RPLND complication. No baseline body composition metrics were associated with post-RPLND complications. CONCLUSION: In men with GCT of the testis, chemotherapy was associated with 6% loss of lean muscle mass and gains in adiposity. Lower skeletal muscle was associated with a higher incidence of chemotherapy-associated AEs. Body composition was not associated with the incidence of post-RPLND complications.

RESUMO

Introduction: Bladder preservation with concurrent chemoradiotherapy after maximum transurethral resection of bladder tumor is an alternative to radical cystectomy in select patients with muscle invasive bladder cancer (MIBC). Concurrent administration of radio-sensitizing chemotherapy and radiation therapy (RT) has been shown to have superior disease control compared with RT alone and can often be administered with modest added toxicity. We sought to describe national patterns of chemotherapy use. Methods: The linked surveillance, epidemiology, and end results (SEER)-Medicare database was used to identify patients with cT2-4, N0/X, M0/X BC who received radiation between 2004 and 2018. Data on demographics, clinicopathologic factors, therapy and outcomes were extracted. Concurrent utilization of chemotherapy with RT was also identified (CRT). Multivariate logistic regression (MVA) models were used to explore factors associated with receipt of chemotherapy and overall survival (OS). Results: 2190 patients met inclusion criteria. Of these, 850 (38.8%) received no chemotherapy. Among those receiving chemotherapy, the most frequent regimens were single agent carboplatin, cisplatin, or gemcitabine. Factors that were independently associated with decreased likelihood of chemotherapy use were increasing age (OR 0.93, CI 0.92 - 0.95), Hispanic race (compared with White, OR 0.62, CI 0.39 - 0.99), cT3 or T4 (compared with cT2, OR 0.70, CI 0.55 - 0.90), and lower National Cancer Institute comorbidity index (OR 0.60, CI 0.51 - 0.70) (p < 0.05). Variables independently associated with increased likelihood of receipt of chemotherapy were married status (OR 1.28, CI 1.06 - 1.54), higher socioeconomic status (OR 1.31, CI 1.06 - 1.64), and later year of diagnosis (OR 1.09, CI 1.06 - 1.12). Receipt of concurrent chemotherapy with RT was associated with superior OS compared with RT alone. Conclusion: Over a third of patients >/65 years old receiving curative-intent RT for MIBC do not receive concurrent chemotherapy. Considering the improvement in oncologic outcomes with CRT over RT alone and more options, such as low dose gemcitabine which can be administered with modest toxicity, efforts are needed to identify barriers to utilization and increase the use of radio-sensitizing chemotherapy.

RESUMO

BACKGROUND: Treatment-related dose-limiting dysuria and irritative bladder symptoms are common in patients receiving intravesical bacillus Calmette-Guérin (BCG) to treat non-muscle-invasive bladder cancer (NMIBC). Acupuncture has been shown to reduce pain and urinary urgency/frequency in other patient populations. OBJECTIVE: To evaluate the feasibility, safety, and tolerability of weekly in-clinic preprocedural acupuncture among patients receiving induction BCG. DESIGN, SETTING, AND PARTICIPANTS: Patients with high-risk NMIBC undergoing induction BCG were randomized 2:1 to a standardized acupuncture protocol (acupuncture) versus the standard-of-care control arm. INTERVENTION: In-office acupuncture prior to each BCG instillation. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSES: Feasibility was assessed via recruitment, retention, and intervention adherence. Acupuncture safety and tolerability were assessed via physician-reported Common Terminology Criteria for Adverse Events version 5.0 and adverse events (AEs). Secondary endpoints included BCG treatment adherence, patient-reported BCG-related toxicity, and bladder cancer-specific and generic (European Organisation for Research and Treatment of Cancer [EORTC]-QLQ-NMIBC-24 and EORTC-QLQ-NMIBC-C30) quality of life (QOL). Subjective assessments of acupuncture acceptability were performed through patient surveys. RESULTS AND LIMITATIONS: A total of 43 individuals were randomized 2:1 to the acupuncture (n = 28) versus control (n = 15) group. The median age was 70.3 yr, and 76% were male. Week 7 follow-up surveys were completed by 93%; six participants withdrew early due to disease progression, refractory gross hematuria, or preference. Acupuncture was delivered successfully prior to each BCG treatment, with no acupuncture-related AEs or interruptions to induction BCG. BCG-attributed AEs were reported by 91% acupuncture and 100% control individuals, including pain (28% vs 43%, p = 0.34) and urinary symptoms (62% vs 79%, p = 0.31). Comparing acupuncture patients with controls, change in QOL over the study period demonstrated greater improvements in median urinary symptoms (9.5, interquartile range [IQR] 0.0-19.0 vs 0.0, IQR -14.3 to 7.1; p = 0.02) among patients in the acupuncture arm. Of the acupuncture patients, 96% reported that acupuncture was "very/extremely helpful," and 91% would recommend acupuncture to other patients. Limitations include modest sample size and single-institution design. CONCLUSIONS: Acupuncture prior to induction BCG treatments is feasible and safe. In this phase 1/2 trial, improved urinary function scores were observed among patients undergoing acupuncture. Patients receiving acupuncture reported high degrees of satisfaction with treatments. PATIENT SUMMARY: We evaluated the safety and feasibility of delivering acupuncture in a urology clinic prior to weekly intravesical bladder cancer treatments with bacillus Calmette-Guérin (BCG) in a randomized controlled trial. We found that acupuncture could be delivered safely prior to weekly BCG instillations and that the use of acupuncture was associated with high patient satisfaction and a decrease in patient-reported urinary symptoms compared with usual care.

RESUMO

BACKGROUND: American Indian and Alaska Native (AIAN) health issues are understudied despite documentation of lower-than-average life expectancy. Urgent surgery is associated with higher rates of postsurgical complications and postoperative death. We assess whether American Indian and Alaska Native (AIAN) patients in Washington State are at greater risk of requiring urgent rather than elective surgery compared with non-Hispanic Whites (NHW). METHODS: We accessed data for the period 2009-2014 from the Washington State Comprehensive Hospital Abstract Reporting System (CHARS) database, which captures all statewide hospital admissions, to examine three common surgeries that are performed both urgently and electively: hip replacements, aortic valve replacements, and spinal fusions. We extracted patient race, age, insurance status, comorbidity, admission type, and procedures performed. We then constructed multivariable logistic regression models to identify factors associated with use of urgent surgical care. RESULTS: AIAN patients had lower mean age at surgery for all three surgeries compared with NHW patients. AIAN patients were at higher risk for urgent surgery for hip replacements (OR = 1.49, 95% CI 1.19-1.88), spinal fusions (OR = 1.39, 95% CI 1.04-1.87), and aortic valve replacements (OR = 2.06, 95% CI 1.12-3.80). CONCLUSION: AIAN patients were more likely to undergo urgent hip replacement, spinal fusion, and aortic valve replacement than NHW patients. AIAN patients underwent urgent surgery at younger ages. Medicaid insurance conferred higher risks for urgent surgery across all surgeries studied. Further research is warranted to more clearly identify the factors contributing to disparities among AIAN patients undergoing urgent surgery.

RESUMO

MATERIALS AND METHODS: An Institutional Review Board-exempt REDCap survey was distributed through the Society of Academic Urologists to all 508 applicants registered for the 2023 Urology Match following the rank list submission deadline on January 10, 2023. The survey closed on February 1, 2023. Responses were anonymized, aggregated, and characterized using descriptive statistics. Thematic mapping of open text comments was performed by 2 reviewers. RESULTS: The response rate was 42% (215/508). Eighty-eight percent of respondents disapproved of the Dobbs ruling. Twenty percent of respondents (15% male/24% female) eliminated programs in states where abortion is illegal. Fifty-nine percent (51% male/70% female) would be concerned for their or their partner's health if they matched in a state where abortion was illegal, and 66% (55% male/82% female) would want their program to assist them or their partner if they required abortion care during residency. Due to the competitive nature of Urology, 68% of applicants reported feeling at least somewhat obligated to apply in states where abortion legislation conflicts with their beliefs. Of the 65 comments provided by respondents, 4 common themes emerged: (1) avoidance of states with restrictive abortion laws; (2) inability to limit applications because of the competitiveness of urology; (3) impacts on personal health care; and (4) desire for advocacy from professional urology organizations. CONCLUSION: The Dobbs ruling will impact the urology workforce by affecting urology applicants' decision-making regarding residency selection and ranking. Although the competitiveness of the Urology Match pressures applicants to apply broadly, many are taking reproductive health care access into consideration.

RESUMO

BACKGROUND: Black individuals in the United States are less likely than White individuals to receive curative therapies despite a 2-fold higher risk of prostate cancer death. While research has described treatment inequities, few studies have investigated underlying causes. METHODS: We analyzed a cohort of 40,137 Medicare beneficiaries (66 and older) linked to the Surveillance Epidemiology and End Results (SEER) cancer registry who had clinically significant, non-metastatic (cT1-4N0M0, grade group 2-5) prostate cancer (diagnosed 2010-2015). Using the Kitagawa-Oaxaca-Blinder decomposition, we assessed the contributions of patient health and health care delivery on the racial difference in localized prostate cancer treatments (radical prostatectomy or radiation). Patient health consisted of comorbid diagnoses, tumor characteristics, SEER site, diagnosis year, and age. Health care delivery was captured as a prediction model with these health variables as predictors of treatment, reflecting current treatment patterns. RESULTS: A total of 72.1% and 78.6% of Black and White patients received definitive treatment, respectively, a difference of 6.5 percentage points. An estimated 15% [95% confidence interval (CI): 6-24] of this treatment difference was explained by measured differences in patient health, leaving the remaining estimated 85% (95% CI: 74-94) attributable to a potentially broad range of health care delivery factors. Limitations included insufficient data to explore how specific health care delivery factors, including structural racism and social determinants, impact differential treatment. CONCLUSIONS: Our results show the inadequacy of patient health differences as an explanation of the treatment inequity. IMPACT: Investing in studies and interventions that support equitable health care delivery for Black individuals with prostate cancer will contribute to improved outcomes.

RESUMO

BACKGROUND: Prostate cancer is the most diagnosed cancer in African American men, yet prostate cancer screening regimens in this group are poorly guided by existing evidence, given underrepresentation of African American men in prostate cancer screening trials. It is critical to optimize prostate cancer screening and early detection in this high-risk group because underdiagnosis may lead to later-stage cancers at diagnosis and higher mortality while overdiagnosis may lead to unnecessary treatment. METHODS: We performed a review of the literature related to prostate cancer screening and early detection specific to African American men to summarize the existing evidence available to guide health-care practice. RESULTS: Limited evidence from observational and modeling studies suggests that African American men should be screened for prostate cancer. Consideration should be given to initiating screening of African American men at younger ages (eg, 45-50 years) and at more frequent intervals relative to other racial groups in the United States. Screening intervals can be optimized by using a baseline prostate-specific antigen measurement in midlife. Finally, no evidence has indicated that African American men would benefit from screening beyond 75 years of age; in fact, this group may experience higher rates of overdiagnosis at older ages. CONCLUSIONS: The evidence base for prostate cancer screening in African American men is limited by the lack of large, randomized studies. Our literature search supported the need for African American men to be screened for prostate cancer, for initiating screening at younger ages (45-50 years), and perhaps screening at more frequent intervals relative to men of other racial groups in the United States.

RESUMO

BACKGROUND: Examine the relationship between exposure to systemic glucocorticoids (steroids) and advanced prostate cancer (PCa) at presentation. Prior work suggested that steroid use may be associated with increased PCa risk. MATERIALS AND METHODS: We queried the linked SEER-Medicare database (2004-2015) to identify PSA screened patients diagnosed with PCa. Criteria for screening included a PSA lab test or DRE exam in both the 12 month and 13 to 36 month periods prior to diagnosis of PCa. Steroid exposure was determined using Medicare Part D and groups were divided based on duration of use in the 3 years prior to diagnosis: controls with no exposure, <30 days, 30 days - 1 year, 1 to 2 years, and >2+ years. Advanced PCa was defined as systemic metastases or regional lymph node metastasis at presentation. Risk estimates for advanced PCa at presentation for steroid exposure groups vs. controls were assessed with univariable and multivariable logistic regression models. RESULTS: We identified 22,920 PSA screened patients diagnosed with PCa of which 29% used glucocorticoids in the exposure period. The mean (SD) duration for glucocorticoid use (in days) among all steroid users was 76.7 days (192.1). On univariable and multivariable analyses, > 2 years of steroid exposure was associated with significantly increased risk for advanced PCa (OR 2.06, 95% CI 1.35-3.14 and OR 1.74, 95% CI 1.12-2.69, respectively). CONCLUSION: In this population-based PSA-screened cohort, prolonged steroid use was associated with increased risk of advanced PCa at diagnosis. With the widespread use of glucocorticoids, it is important to consider the role steroids may play in PCa pathogenesis.

RESUMO

PURPOSE: US states eased licensing restrictions on telemedicine during the COVID-19 pandemic, allowing interstate use. As waivers expire, optimal uses of telemedicine must be assessed to inform policy, legislation, and clinical care. We assessed whether telemedicine visits provided the same patient experience as in-person visits, stratified by in- vs out-of-state residence, and examined the financial burden. MATERIALS AND METHODS: Patients seen in person and via telemedicine for urologic cancer care at a major regional cancer center received a survey after their first appointment (August 2019-June 2022) on satisfaction with care, perceptions of communication during their visit, travel time, travel costs, and days of work missed. RESULTS: Surveys were completed for 1058 patient visits (N = 178 in-person, N = 880 telemedicine). Satisfaction rates were high for all visit types, both interstate and in-state care (mean score 60.1-60.8 [maximum 63], P > .05). More patients convening interstate telemedicine would repeat that modality (71%) than interstate in-person care (61%) or in-state telemedicine (57%). Patients receiving interstate care had significantly higher travel costs (median estimated visit costs $200, IQR $0-$800 vs median $0, IQR $0-$20 for in-state care, P < .001); 55% of patients receiving interstate in-person care required plane travel and 60% required a hotel stay. CONCLUSIONS: Telemedicine appointments may increase access for rural-residing patients with cancer. Satisfaction outcomes among patients with urologic cancer receiving interstate care were similar to those of patients cared for in state; costs were markedly lower. Extending interstate exemptions beyond COVID-19 licensing waivers would permit continued delivery of high-quality urologic cancer care to rural-residing patients.

RESUMO

Objective: US patients have increased access to their medical records, yet the information is not always understandable. To improve patient understanding, we tested a patient-centered pathology report (PCPR) containing results for recent colon cancer screening or surveillance colonoscopy. Methods: A pilot randomized trial assessed the impact of addition of the PCPR to a standard pathology report on knowledge accuracy, decisional self-efficacy and control, and therapeutic alliance. Results: 55 participants were enrolled; 20 participants in the intervention group and 24 controls completed follow-up. There was no significant difference in polyp knowledge between groups at baseline or 30-days, with similar confidence in understanding their diagnoses, decisional self-efficacy, and therapeutic alliance. Most participants receiving a PCPR felt that it helped them understand their diagnosis better and should always be provided with the standard pathology report. Conclusion: Although patient attitudes toward the PCPR were positive, receiving it did not significantly improve knowledge accuracy or measures of self-efficacy. Further iterations should be explored to communicate key knowledge about colorectal polyp results. Innovation: A stakeholder-driven approach to PCPR development facilitated construction of a personalized document that has potential to increase patient's understanding for their results and needed follow-up.

RESUMO

BACKGROUND: Some reports suggest that women with type 1 diabetes (T1D) have a greater burden of female sexual dysfunction (FSD) than women without T1D, but the etiology of this elevated risk is poorly understood. AIM: To examine the associations between FSD and urinary incontinence/lower urinary tract symptoms (UI/LUTS) in women with T1D and to evaluate how depression may mediate these relationships. METHODS: LUTS and UI symptoms were assessed in women with T1D who participated in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Study. Multivariable logistic regression models estimated associations between FSD and UI/LUTS (overall and specific domains) and the impact of depression on these associations. OUTCOMES: FSD was measured with the Female Sexual Function Index-Reduced. RESULTS: In total, 499 self-reported sexually active women completed validated assessments of sexual and urinary function (mean ± SD age, 47.7 ± 7.6 years; T1D duration, 23.4 ± 5.15 years). FSD was reported in 232 (46%) responders. The frequency of UI and LUTS was 125 (25.1%) and 96 (19.2%), respectively. Neither UI nor its subcategories (urge, stress) were associated with FSD. Although LUTS (odds ratio [OR], 1.75; 95% CI, 1.09-2.77) and its symptoms of urgency (OR, 1.99; 95% CI, 1.09-3.61) and incomplete emptying (OR, 2.44; 95% CI, 1.23-4.85) were associated with FSD, these associations were attenuated following adjustment for depression and antidepressant medication use. Depression indicators were independently associated with FSD overall and across domains. CLINICAL IMPLICATIONS: The complex interplay of voiding dysfunction, mental health, and sexual function warrants further investigation to understand the potential implications for patient assessment, goal setting, treatment, and care planning. STRENGTHS AND LIMITATIONS: Data are from a prospective study of individuals with T1D. These results are unable to explore cause-and-effect relationships among LUTS, UI, depression, and FSD. The sample may not be representative of the general population of women with T1D. Because participants in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Study are mostly White, generalizing the findings to other races and to type 2 diabetes may not be appropriate. While exclusion of sexually inactive women likely biases our findings toward the null, this design element permitted study of LUTS and UI in relation to aspects of FSD, the primary objective of this study. CONCLUSIONS: The significant associations between LUTS/UI and FSD among middle-aged women with T1D were greatly attenuated when depression was considered a mediating factor.

RESUMO

OBJECTIVES: Early identification of lung cancer on chest radiographs improves patient outcomes. Artificial intelligence (AI) tools may increase diagnostic accuracy and streamline this pathway. This study evaluated the performance of commercially available AI-based software trained to identify cancerous lung nodules on chest radiographs. DESIGN: This retrospective study included primary care chest radiographs acquired in a UK centre. The software evaluated each radiograph independently and outputs were compared with two reference standards: (1) the radiologist report and (2) the diagnosis of cancer by multidisciplinary team decision. Failure analysis was performed by interrogating the software marker locations on radiographs. PARTICIPANTS: 5722 consecutive chest radiographs were included from 5592 patients (median age 59 years, 53.8% women, 1.6% prevalence of cancer). RESULTS: Compared with radiologist reports for nodule detection, the software demonstrated sensitivity 54.5% (95% CI 44.2% to 64.4%), specificity 83.2% (82.2% to 84.1%), positive predictive value (PPV) 5.5% (4.6% to 6.6%) and negative predictive value (NPV) 99.0% (98.8% to 99.2%). Compared with cancer diagnosis, the software demonstrated sensitivity 60.9% (50.1% to 70.9%), specificity 83.3% (82.3% to 84.2%), PPV 5.6% (4.8% to 6.6%) and NPV 99.2% (99.0% to 99.4%). Normal or variant anatomy was misidentified as an abnormality in 69.9% of the 943 false positive cases. CONCLUSIONS: The software demonstrated considerable underperformance in this real-world patient cohort. Failure analysis suggested a lack of generalisability in the training and testing datasets as a potential factor. The low PPV carries the risk of over-investigation and limits the translation of the software to clinical practice. Our findings highlight the importance of training and testing software in representative datasets, with broader implications for the implementation of AI tools in imaging.

RESUMO

INTRODUCTION: Patients with mental health disorders are at risk for receiving inequitable cancer treatment, likely resulting from various structural, social, and health-related factors. This study aims to assess the relationship between mental health disorders and the use of definitive treatment in a population-based cohort of those with localized, clinically significant prostate cancer. METHODS: We conducted a cohort study analysis in SEER (Surveillance, Epidemiology, and End Results)-Medicare (2004-2015). History of a mental health disorder was defined as presence of specific ICD (International Classification of Diseases)-9 or ICD-10 diagnostic codes in the 2 years preceding cancer diagnosis. Descriptive statistics were performed using Wilcoxon rank-sum and χ2 testing. Multivariable logistic regression was used to evaluate the relationship between mental health disorders and definitive treatment utilization (defined as surgery or radiation). RESULTS: Of 101,042 individuals with prostate cancer, 7,945 (7.8%) had a diagnosis of a mental health disorder. They were more likely to be unpartnered, have a lower socioeconomic status, and less likely to receive definitive treatment (61.8% vs 68.2%, P < .001). Definitive treatment rates were >66%, 62.8%, 60.3%, 58.2%, 54.3%, and 48.1% for post-traumatic stress disorder, depressive disorder, bipolar disorder, anxiety disorder, substance abuse disorder, and schizophrenia, respectively. After adjusting for age, race and ethnicity, marital status and socioeconomic status, history of a mental health disorder was associated with decreased odds of receiving definitive treatment (OR 0.74, 95% CI 0.66-0.83). CONCLUSIONS: Individuals with mental health disorders and prostate cancer represent a vulnerable population; careful attention to clinical and social needs is required to support appropriate use of beneficial treatments.

RESUMO

OBJECTIVE: To evaluate attitudes of women in urology regarding the Supreme Court ruling Dobbs v. Jackson Women's Health Organization, including impacts on personal/professional decision-making and the urology workforce. METHODS: An IRB-exempt survey including Likert questions on participant views and free text questions was distributed to 1200 members of the Society of Women in Urology on 9/2/2022. Participants were medical students, urology residents, fellows, and practicing/retired urologists over 18. Responses were anonymous and aggregated. Quantitative responses were characterized with descriptive statistics and free-text responses were analyzed using thematic mapping. To complement this analysis, urologist density was mapped by county using 2021 National Provider Identifier data. State abortion laws were categorized based on Guttmacher Institute data on 10/20/2022. Data were analyzed using logistic regression, Poisson regression, and multiple linear regression. RESULTS: 329 respondents completed the survey. 88% disagree/strongly disagree with the Dobbs ruling. 42% of trainees may have changed their rank list if current abortion laws existed during their match. 60% of respondents said Dobbs will impact where they choose their next job. 61.5% of counties had zero urologists in 2021, 76% of which were in states with restrictive abortion laws. Urologist density was inversely associated with abortion law restrictiveness compared with the most protective counties. CONCLUSION: The Dobbs ruling will significantly impact the urology workforce. Trainees may change how they rank programs in states with restrictive abortion laws, and urologists may consider abortion laws when choosing jobs. Restrictive states are at higher risk for worsening access to urologic care.

RESUMO

BACKGROUND: Patients residing in rural areas with urologic cancers confront significant obstacles in obtaining oncologic care. In the Pacific Northwest, a sizeable portion of the population lives in a rural county. Telehealth offers a potential access solution. METHODS: Patients receiving urologic care through telehealth or an in-person appointment at the Fred Hutchinson Cancer Center in Seattle, Washington, were surveyed to assess appointment-related satisfaction and travel costs. Patients' residences were classified as rural or urban based on their self-reported ZIP code. Median patient satisfaction scores and appointment-related travel costs were compared by rural versus urban residence within telehealth and in-person appointment groups using Wilcoxon signed-rank or χ2 testing. RESULTS: A total of 1091 patients seen for urologic cancer care between June 2019 and April 2022 were included, 28.7% of which resided in a rural county. Patients were mostly non-Hispanic White (75%) and covered by Medicare (58%). Among rural-residing patients, telehealth and in-person appointment groups had the same median satisfaction score (61; interquartile ratio, 58, 63). More rural-residing than urban-residing patients in the telehealth appointment groups strongly agreed that "Considering the cost and time commitment of my appointment, I would choose to meet with my provider in this setting in the future" (67% vs. 58%, p = .03). Rural-residing patients with in-person appointments carried a higher financial burden than those with telehealth appointments (medians, $80 vs. $0; p <.001). CONCLUSIONS: Appointment-related costs are high among rural-residing patients traveling for urologic oncologic care. Telehealth provides an affordable solution that does not compromise patient satisfaction.

RESUMO

INTRODUCTION: To examine oncologic outcomes and response to neoadjuvant chemotherapy (NAC) in patients with sarcomatoid urothelial carcinoma (SUC) treated with radical cystectomy (RC). MATERIALS AND METHODS: We retrospectively queried our institutional database (2003-18) and Surveillance, Epidemiology, and End Results (SEER)-Medicare (2004-2015) for patients with cT2-4, N0-2, M0 SUC and conventional UC (CUC) treated with RC. Clinicopathologic characteristics were described using descriptive statistics (t test, χ2-test and log-rank-test for group comparison). Overall (OS) and recurrence-free-survival (RFS) after RC were estimated with the Kaplan Meier method and associations with OS were evaluated with Cox proportional hazards models. RESULTS: We identified 38 patients with SUC and 287 patients with CUC in our database, and 190 patients with SUC in SEER-Medicare. In the institutional cohort, patients with SUC versus CUC had higher rates of pT3/4 stage (66% vs. 35%, P < 0.001), lower rates of ypT0N0 (6% vs. 35%, P = .02), and worse median OS (17.5 vs. 120 months, P < .001). Further, patients with SUC in the institutional versus SEER-Medicare cohort had similar median OS (17.5 vs. 21 months). In both cohorts, OS was comparable between patients with SUC undergoing NAC+RC vs. RC alone (17.5 vs. 18.4 months, P = .98, institutional cohort; 24 vs. 20 months, P = .56, SEER cohort). In Cox proportional hazards models for the institutional RC cohort, SUC was independently associated with worse OS (HR 2.3, CI 1.4-3.8, P = .001). CONCLUSION: SUC demonstrates poor pathologic response to NAC and worse OS compared with CUC, with no OS benefit associated with NAC. A unique pattern of rapid abdominopelvic cystic recurrence was identified.

RESUMO

Importance: Early pregnancy loss (EPL), or miscarriage, is the most common complication of early pregnancy, and many patients experiencing EPL present to the emergency department (ED). Little is known about how patients who present to the ED with EPL differ from those who present to outpatient clinics and how their management and outcomes differ. Objective: To compare the management and outcomes of patients with EPL who present to the ED vs outpatient clinics. Design, Setting, and Participants: This retrospective cohort study used the IBM MarketScan Research Database, a national insurance claims database. Participants were pregnant people aged 15 to 49 years in the US who presented to either an ED or outpatient clinic for initial diagnosis of EPL from October 2015 through December 2019. Data analysis was performed from May 2021 to March 2022. Exposures: The primary exposure was location of service (ED vs outpatient clinic). Other exposures of interest included demographic characteristics, current pregnancy history, and comorbidities. Main Outcomes and Measures: The primary outcome was EPL management type (surgical, medication, or expectant management). Complications, including blood transfusion and hospitalization, and characteristics associated with location of service were also evaluated. Bivariable analyses and multivariable logistic regression were used for data analysis. Results: A total of 117 749 patients with EPL diagnoses were identified, with a mean (SD) age of 31.8 (6.1) years. Of these patients, 20 826 (17.7%) initially presented to the ED, and 96 923 (82.3%) presented to outpatient clinics. Compared with the outpatient setting, patients in the ED were less likely to receive surgical (2925 patients [14.0%] vs 23 588 patients [24.3%]) or medication (1116 patients [5.4%] vs 10 878 patients [11.2%]) management. In the adjusted analysis, characteristics associated with decreased odds of active (surgical or medication) vs expectant management included ED (vs outpatient) presentation (adjusted odds ratio [aOR], 0.46; 95% CI, 0.44-0.47), urban location (aOR, 0.87; 95% CI, 0.82-0.91), and being a dependent on an insurance policy (vs primary policy holder) (aOR, 0.71; 95% CI, 0.67-0.74); whereas older age (aOR per 1-year increase 1.01; 95% CI, 1.01-1.01), established prenatal care (aOR, 2.35; 95% CI, 2.29-2.42), and medical comorbidities (aOR, 1.05; 95% CI, 1.02-1.09) were associated with increased odds of receiving active management. Patients in the ED were more likely than those in outpatient clinics to need a blood transfusion (287 patients [1.4%] vs 202 patients [0.2%]) or hospitalization (463 patients [2.2%] vs 472 patients [0.5%]), but complications were low regardless of location of service. Conclusions and Relevance: In this cohort study of privately insured patients with EPL, differences in management between the ED vs outpatient setting may reflect barriers to accessing comprehensive EPL management options. More research is needed to understand these significant differences in management approaches by practice setting, and to what extent EPL management reflects patient preferences in both outpatient and ED settings.

RESUMO

BACKGROUND: US Black men are twice as likely to die from prostate cancer as men of other races. Lower quality care may contribute to this higher death rate. METHODS: Sociodemographic and clinical data were obtained for men in Surveillance, Epidemiology, and End Results-Medicare diagnosed with clinically localized prostate cancer (cT1-4N0/xM0/x) and managed primarily by radical prostatectomy (2005-2015). Surgical volume was determined for facility and surgeon. Relationships between race, surgeon and/or facility volume, and characteristics of treating facility with survival (all-cause and cancer-specific) were assessed using multivariable Cox regression and competing risk analysis. RESULTS: Black men represented 6.7% (n = 2123) of 31,478 cohort. They were younger at diagnosis, had longer time from diagnosis to surgery, lower socioeconomic status, higher prostate-specific antigen (PSA), and higher comorbid status compared with men of other races (p < .001). They were less likely to receive care from a surgeon or facility in the top volume percentile (p < .001); less likely to receive surgical care at a National Cancer Institute-designated cancer center and more likely seen at a minority-serving hospital; and less likely to travel ≥50 miles for surgical care. On multivariable analysis stratified by surgical volume, Black men receiving care from a surgeon or facility with lower volumes demonstrated increased risk of prostate cancer mortality (hazard ratio, 1.61; 95% confidence interval, 1.01-2.69) adjusting for age, clinical stage, PSA, and comorbidity index. CONCLUSIONS: Black Medicare beneficiaries with prostate cancer more commonly receive care from surgeons and facilities with lower volumes, likely affecting surgical quality and outcomes. Access to high-quality prostate cancer care may reduce racial inequities in disease outcomes, even among insured men. PLAIN LANGUAGE SUMMARY: Black men are twice as likely to die of prostate cancer than other US men. Lower quality care may contribute to higher rates of prostate cancer death. We used surgical volume to evaluate the relationship between race and quality of care. Black Medicare beneficiaries with prostate cancer more commonly received care from surgeons and facilities with lower volumes, correlating with a higher risk of prostate cancer death and indicating scarce resources for care. Access to high-quality prostate cancer care eases disparities in disease outcomes. Patient-centered interventions that increase access to high-quality care for Black men with prostate cancer are needed.

RESUMO

INTRODUCTION: Cisplatin-based neoadjuvant chemotherapy (NAC) followed by cystectomy is the standard for muscle-invasive bladder cancer (MIBC), however, NAC confers only a small survival benefit and new strategies are needed to increase its efficacy. Pre-clinical data suggest that in response to DNA damage the tumor microenvironment (TME) adopts a paracrine secretory phenotype dependent on mTOR signaling which may provide an escape mechanism for tumor resistance, thus offering an opportunity to increase NAC effectiveness with mTOR blockade. PATIENTS & METHODS: We conducted a phase I/II clinical trial to assess the safety and efficacy of gemcitabine-cisplatin-rapamycin combination. Grapefruit juice was administered to enhance rapamycin pharmacokinetics by inhibiting intestinal enzymatic degradation. Phase I was a dose determination/safety study followed by a single arm Phase II study of NAC prior to radical cystectomy evaluating pathologic response with a 26% pCR rate target. RESULTS: In phase I, 6 patients enrolled, and the phase 2 dose of 35 mg rapamycin established. Fifteen patients enrolled in phase II; 13 were evaluable. Rapamycin was tolerated without serious adverse events. At the preplanned analysis, the complete response rate (23%) did not meet the prespecified level for continuing and the study was stopped due to futility. With immunohistochemistry, successful suppression of the mTOR signaling pathway in the tumor was achieved while limited mTOR activity was seen in the TME. CONCLUSION: Adding rapamycin to gemcitabine-cisplatin therapy for patients with MIBC was well tolerated but failed to improve therapeutic efficacy despite evidence of mTOR blockade in tumor cells. Further efforts to understand the role of the tumor microenvironment in chemotherapy resistance is needed.
