Bladder Cancer Survivors Who Do Not Smoke Have Better Longitudinal Health-Related Quality of Life Measures: An Assessment of the Comparative Effectiveness of Survivorship Health in Bladder Cancer (CEASE-BC) Study.

PURPOSE: Cigarette smoking is the most common risk factor for the development of bladder cancer (BC), yet there is a paucity of data characterizing the relationship between smoking status and longitudinal health-related quality of life (HRQoL) outcomes in patients with BC. We examined the association between smoking status and HRQoL among patients with BC. MATERIALS AND METHODS: Data were sourced from a prospective, longitudinal study open between 2014 and 2017, which examined HRQoL in patients aged ≥ 18 years old diagnosed with BC across North Carolina. The QLQ-C30 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire core instrument) was administered at 3, 12, and 24 months after BC diagnosis. Our primary exposure of interest was current smoking status. Linear regression using generalized estimating equations was used to analyze the relationship between smoking status and various domains of the QLQ-C30. RESULTS: A total of 154 patients enrolled in the study. Eighteen percent were classified as smoking at 3 months from diagnosis, and packs per day ranged from < 0.5 to 2. When controlling for time from diagnosis, demographic covariates, cancer stage, and treatment type, mean differences for physical function (7.4), emotional function (5.6), and fatigue measures (-8.2) were significantly better for patients with BC who did not smoke. CONCLUSIONS: Patients with BC who do not smoke have significantly better HRQoL scores in the domains of physical function, emotional function, and fatigue. These results underscore the need to treat smoking as an essential component of BC care.

Smoking characteristics and years since quitting smoking of US adults diagnosed with lung and bladder cancer: A national health and nutrition examination survey analysis.

PURPOSE: Smoking is a recognized risk factor for bladder BC and lung cancer LC. We investigated the enduring risk of BC after smoking cessation using U.S. national survey data. Our analysis focused on comparing characteristics of LC and BC patients, emphasizing smoking status and the latency period from smoking cessation to cancer diagnosis in former smokers. MATERIALS AND METHODS: We analyzed data from the National Health and Examination Survey (2003-2016), identifying adults with LC or BC history. Smoking status (never, active, former) and the interval between quitting smoking and cancer diagnosis for former smokers were assessed. We reported descriptive statistics using frequencies and percentages for categorical variables and median with interquartile ranges (IQR) for continuous variables. RESULTS: Among LC patients, 8.9% never smoked, 18.9% active smokers, and 72.2% former smokers. Former smokers had a median interval of 8 years (IQR 2-12) between quitting and LC diagnosis, with 88.3% quitting within 0-19 years before diagnosis. For BC patients, 26.8% never smoked, 22.4% were active smokers, and 50.8% former smokers. Former smokers had a median interval of 21 years (IQR 14-33) between quitting and BC diagnosis, with 49.3% quitting within 0-19 years before diagnosis. CONCLUSIONS: BC patients exhibit a prolonged latency period between smoking cessation and cancer diagnosis compared to LC patients. Despite smoking status evaluation in microhematuria, current risk stratification models for urothelial cancer do not incorporate it. Our findings emphasize the significance of long-term post-smoking cessation surveillance and advocate for integrating smoking history into future risk stratification guidelines.

Primary Retroperitoneal Lymph Node Dissection for Seminoma Metastatic to the Retroperitoneum.

PURPOSE: Primary surgical treatment with retroperitoneal lymph node dissection aims to accurately stage and treat patients with node-positive pure seminoma while avoiding long-term risks of chemotherapy or radiation, traditional standard-of-care treatments. MATERIALS AND METHODS: We reported the pathologic and oncologic outcomes of patients with pure seminoma treated with primary retroperitoneal lymph node dissection in a retrospective, single-institution case series over 10 years. The primary outcome was 2-year recurrence-free survival stratified by adjuvant management strategy (surveillance vs adjuvant chemotherapy). RESULTS: Forty-five patients treated with primary retroperitoneal lymph node dissection for pure testicular seminoma metastatic to the retroperitoneum were identified. Median size of largest lymph node before surgery was 1.8 cm. Viable germ cell tumor, all of which was pure seminoma, was found in 96% (n=43) of patients. The median number of positive nodes and nodes removed was 2 and 54, respectively. Median positive pathologic node size was 2 cm (IQR 1.4-2.5 cm, range 0.1-5 cm). Four of 29 patients managed with postoperative surveillance experienced relapse; 2-year recurrence-free survival was 81%. Median follow-up for those managed with surveillance who did not relapse was 18.5 months. There were no relapses in the retroperitoneum, visceral recurrences, or deaths. Among the 16 patients who received adjuvant treatment, 1 patient experienced relapse in the pelvis at 19 months. CONCLUSIONS: Primary retroperitoneal lymph node dissection for pure seminoma with low-volume metastases to the retroperitoneum is safe and effective, allowing most patients to avoid long-term toxicities from chemotherapy or radiation.

Surgical outcomes of cytoreductive nephrectomy in patients receiving systemic immunotherapy for advanced renal cell carcinoma.

PURPOSE: The use of systemic immune checkpoint blockade before surgery is increasing in patients with metastatic renal cell carcinoma, however, the safety and feasibility of performing consolidative cytoreductive nephrectomy after the administration of systemic therapy are not well described. PATIENTS AND METHODS: A retrospective review of patients undergoing nephrectomy was performed using our prospectively maintained institutional database. Patients who received preoperative systemic immunotherapy were identified, and the risk of postoperative complications were compared to those who underwent surgery without upfront systemic treatment. Perioperative characteristics and surgical complications within 90 days following surgery were recorded. RESULTS: Overall, we identified 220 patients who underwent cytoreductive nephrectomy from April 2015 to December 2022, of which 46 patients (21%) received systemic therapy before undergoing surgery. Unadjusted rates of surgical complications included 20% (n = 35) in patients who did not receive upfront systemic therapy and 20% (n = 9) in those who received upfront systemic immunotherapy. In our propensity score analysis, there was no statistically significant association between receipt of upfront immunotherapy and 90-day surgical complications [odds ratio (OR): 1.82, 95% confidence interval (CI): 0.59-5.14; P = 0.3]. This model, however, demonstrated an association between receipt of upfront immunotherapy and an increased odds of requiring a blood transfusion [OR: 4.53, 95% CI: 1.83-11.7; P = 0.001]. CONCLUSION: In our cohort, there was no significant difference in surgical complications among patients who received systemic therapy before surgery compared to those who did not receive upfront systemic therapy. Cytoreductive nephrectomy is safe and with low rates of complications following the use of systemic therapy.

Bladder cancer patient and provider perspectives on smoking cessation.

BACKGROUND: Smoking is the most common risk factor for bladder cancer and is associated with adverse clinical and cancer-related outcomes. Increasing understanding of the patient and provider perspectives on smoking cessation may provide insight into improving smoking cessation rates among bladder cancer survivors. We sought to inform strategies for providers promoting cessation efforts and help patients quit smoking. METHODS: Using a modified Delphi process with multidisciplinary input from bladder cancer providers, researchers, and a patient advocate, 2 surveys were created for bladder cancer patients and providers. Surveys included multiple-choice questions and free answers. The survey was administered electronically and queried participants' perspectives on barriers and facilitators associated with smoking cessation. Survey responses were anonymous, and participants were provided with a $20 Amazon gift card for participating. Patients were approached through the previously established Bladder Cancer Advocacy Network (BCAN) Patient Survey Network, an online bladder cancer patient and caregiver community. Providers were recruited from the Society of Urologic Oncology (SUO) and the Large Urology Group Practice Association (LUGPA). RESULTS: From May to June 2021, 308 patients and 103 providers completed their respective surveys. Among patients who quit smoking, most (64%) preferred no pharmacologic intervention ("cold turkey") followed by nicotine replacement therapy (28%). Repeated efforts at cessation commonly occurred, and 67% reported making more than one attempt at quitting prior to eventual smoking cessation. Approximately 1 in 10 patients were unaware of the association between bladder cancer and smoking. Among providers, 75% felt that barriers to provide cessation include a lack of clinical time, adequate training, and reimbursement concerns. However, 79% of providers endorsed a willingness to receive continuing education on smoking cessation. CONCLUSIONS: Bladder cancer patients utilize a variety of cessation strategies with "cold turkey" being the most used method, and many patients make multiple attempts at smoking cessation. Providers confront multiple barriers to conducting smoking cessation, including inadequate time and training in cessation methods; however, most would be willing to receive additional education. These results inform future interventions tailored to bladder cancer clinicians to better support provider efforts to provide smoking cessation counseling.

Novel approaches to redesign surveillance strategies following orchiectomy for localized testicular cancer: a narrative review.

Background and Objective: Surveillance is the preferred management strategy for most men with clinical stage I testicular cancer after orchiectomy. However, frequent office visits, imaging tests, and laboratory studies place a significant burden on patients, which may contribute to poor compliance with guideline-recommended surveillance regimens. Identifying strategies to overcome these barriers may help improve quality of life, reduce costs, and improve adherence for patients. We reviewed evidence for three strategies that may help with surveillance redesign: telemedicine, implementing microRNA (miRNA) as a biomarker, and novel imaging protocols. Methods: A web-based literature search for novel imaging strategies, diagnostic utility of miRNA, and telehealth as they relate to early-stage testicular germ cell cancer was completed during the month of August 2022. We focused our search on contemporary PubMed-indexed and Google Scholar-registered manuscripts written in English. Supportive data sourced from current guideline statements were also included. Evidence was compiled for narrative review. Key Content and Findings: Telemedicine is a safe and acceptable platform for urologic cancer follow-up care, but it requires further study specifically among men with testicular cancer. Access to care may either be improved or reduced depending on system- and patient-level characteristics and should be implemented with this in mind. miRNA may potentially be a helpful biomarker for men with localized disease, but further research on diagnostic accuracy and marker kinetics are needed before implementing it into routine surveillance strategies or using it to deviate from long-standing surveillance regiments. Novel imaging strategies with less frequent imaging and the use of magnetic resonance imaging (MRI) instead of computed tomography (CT) appear to be non-inferior in clinical trials. However, use of MRI requires expert radiologist availability and may be more costly with a lower ability to detect small, early recurrences when used in routine practice. Conclusions: Using telemedicine, integrating miRNA as a tumor marker, and adopting less intensive imaging strategies may improve guideline-concordant surveillance for men with localized testicular cancer. Future studies are needed to assess the risks and benefits of using these novel approaches separately or together.

Toward the Deimplementation of Computed Tomography Urogram for Patients With Low- to Intermediate-risk Microscopic Hematuria: A Mixed-method Study of Factors Influencing Continued Use.

INTRODUCTION: Citing high costs, limited diagnostic benefit, and ionizing radiation-associated risk from CT urogram, in 2020 the AUA revised its guidelines from recommending CT urogram for all patients with microscopic hematuria to a deintensified risk-stratified approach, including the deimplementation of low-value CT urogram (ie, not recommending CT urogram for patients with low- to intermediate-risk microscopic hematuria). Adherence to revised guidelines and reasons for continued low-value CT urogram are unknown. METHODS: With the overarching objective of improving guideline implementation, we used a mixed-method convergent explanatory design with electronic health record data for a retrospective cohort at a single academic tertiary medical center in the southeastern United States and semistructured interviews with urology and nonurology providers to describe determinants of low-value CT urogram following guideline revision. RESULTS: Of 391 patients with microscopic hematuria, 198 (51%) had a low-value CT urogram (136 [69%] pre-guideline revision, 62 [31%] postrevision). The odds of ordering a low-value CT urogram were lower after guideline revisions, but the change was not statistically significant (OR: 0.44, P = .08); odds were 1.89 higher (P = .06) among nonurology providers than urology providers, but the difference was not statistically significant. Provider interviews suggested low-value CT urogram related to nonurology providers' limited awareness of revised guidelines, the role of clinical judgment in microscopic hematuria evaluation, and professional and patient influences. CONCLUSIONS: Our findings suggest low-value CT urogram deimplementation may be improved with guidelines and implementation support directed at both urology and nonurology providers and algorithms to support guideline-concordant microscopic hematuria evaluation approaches. Future studies should test these strategies.

Urologists' Perceptions and Practices Related to Patient Smoking and Cessation: A National Assessment From the 2021 American Urological Association Census.

OBJECTIVE: To assess urologists' perceptions and practices related to smoking and smoking cessation. MATERIALS AND METHODS: Six survey questions were designed to assess beliefs, practices, and determinants related to tobacco use assessment and treatment (TUAT) in outpatient urology clinics. These questions were included in an annual census survey (2021) offered to all practicing urologists. Responses were weighted to represent the practicing US population of nonpediatric urologists (N = 12,852). The primary outcome was affirmative responses to the question, "Do you agree it is important for urologists to screen for and provide smoking cessation treatment to patients in the outpatient clinic?" Practice patterns, perceptions, and opinions of optimal care delivery were assessed. RESULTS: In total, 98% of urologists agreed (27%) or strongly agreed (71%) that cigarette smoking is a significant contributor to urologic disease. However, only 58% agreed that TUAT is important in urology clinics. Most urologists (61%) advise patients who smoke to quit but do not provide additional cessation counseling or medications or arrange follow-up. The most frequently identified barriers to TUAT were lack of time (70%), perceptions that patients are unwilling to quit (44%), and lack of comfort prescribing cessation medications (42%). Additionally, 72% of respondents stated that urologists should provide a recommendation to quit and refer patients for cessation support. CONCLUSION: TUAT does not routinely occur in an evidence-based fashion in outpatient urology clinics. Addressing established barriers and facilitating these practices with multilevel implementation strategies can promote tobacco treatment and improve outcomes for patients with urologic disease.

Bladder Cancer Carcinogens: Opportunities for Risk Reduction.

Bladder cancer at an individual level is likely to be the consequence of repeated, long-term exposure to one or more known bladder carcinogens, some of which are endemic or unavoidable in daily life, in addition to host factors. This Mini-Review highlights exposures that are associated with higher risk of bladder cancer, summarizes the evidence for each association, and suggests strategies to decrease risk at both individual and population levels. PATIENT SUMMARY: Tobacco smoking, exposure to certain chemicals in your diet, environment, or workplace, urinary infections, and certain medications can increase your risk of bladder cancer.

Attitudes, Perceptions, and Use of Cancer-based Genetic Testing Among Healthy U.S. Adults and Those With Prostate or Breast/Ovarian Cancer.

INTRODUCTION: Differences in public awareness and uptake of genetic testing among patients with inheritable cancers are not well understood. The purpose of this study is to examine self-reported rates of undergoing cancer-specific genetic testing in patients with breast/ovarian cancer vs prostate cancer from a nationally representative sample of U.S. PATIENTS: Secondary objectives include examining sources of genetic testing information and perceptions of genetic testing for both patient populations as well as the general public. METHODS: Data from the National Cancer Institute's Health Information National Trends Survey 5, Cycle 4 were used to generate nationally representative estimates of adults living in the U.S. Our exposure of interest was patient reported cancer history categorized as having: (1) either breast or ovarian cancer, (2) prostate cancer, or (3) no history of cancer. χ2 testing was used to compare differences among categorical variables. RESULTS: In a nationally representative sample of 231.7 million adults, 3.7 million adults reported a history of breast/ovarian cancer while 1.5 million patients reported a history of prostate cancer; 52.3% of patients with breast/ovarian cancer vs 1.0% with prostate cancer reported undergoing cancer-specific genetic testing (P = .001). Patients with prostate cancer were less aware of cancer-specific genetic testing than either individuals with breast/ovarian cancer or adults without a cancer history (19.7% vs 64.7% vs 35.8%, respectively; P = .003). Health care professionals were the most common source of genetic testing information for patients with breast/ovarian cancer whereas the Internet was the most common source for patients with prostate cancer. CONCLUSIONS: Our results suggest a lack of awareness and limited utilization of genetic testing among patients with prostate cancer relative to breast/ovarian cancer. Patients with prostate cancer cite the Internet and social media as sources of information, which may be an avenue for more optimal dissemination of evidence-based information.

Diversity, equity, and inclusion in genitourinary clinical trials leading to FDA novel drug approval: An assessment of the FDA center for drug evaluation and research drug trials snapshot.

To determine the distribution of race and ethnicity among genitourinary oncology trial participants leading to FDA approval of novel molecular entities/biologics. Secondarily, we evaluated whether the proportion of Black participants in clinical trials increased over time. We quired the FDA Center for Drug Evaluation and Research Drug Trials Snapshot (DTS) between 2015 and 2020 for urologic oncology clinical trials leading to FDA approval of novel drugs. Enrollment data was stratified by race and ethnicity. Cochran-Armitage Trend tests were used to examine changes in Black patient participation over years. Nine clinical trials were identified that led to FDA approval of 5 novel molecular entities for prostate and 4 molecular entities for urothelial carcinoma treatment. Trials for prostate cancer included 5202 participants of which 69.8% were White, 4.0% Black, 11.0% Asian, 3.6% Hispanic, <1% American Indian/Alaska Native or Native Hawaiian/Pacific Islander, 3% other. Trials in urothelial carcinoma had 704 participants of which 75.1% were male, 80.8% White, 2.3% Black, 2.4% Hispanic, <1% American Indian/Alaska Native or Native Hawaiian/Pacific Islander, 5% other. Black participation rates over time did not change for urothelial (P = 0.59) or the combined cancer cohort (P = 0.29). Prostate cancer enrollment trends among Black participant declined over time (P = 0.03). Participants in genitourinary clinical trials leading to FDA approval of novel drugs are overwhelmingly white. Involving stakeholders who represent the needs and interests of underrepresented populations in the design and implementation of clinical trials of novel agents may be a strategy to increase diversity, equity, and inclusion among genitourinary clinical trials.

Impact of smoking on urologic cancers: a snapshot of current evidence.

PURPOSE: The purpose of this paper is to present evidence regarding the associations between smoking and the following urologic cancers: prostate, bladder, renal, and upper tract urothelial cancer (UTUC). METHODS: This is a narrative review. PubMed was queried for evidence-based analyses and trials regarding the associations between smoking and prostate, bladder, renal, and UTUC tumors from inception to September 1, 2022. Emphasis was placed on articles referenced in national guidelines and protocols. RESULTS: Prostate-multiple studies associate smoking with higher Gleason score, higher tumor stage, and extracapsular invasion. Though smoking has not yet been linked to tumorigenesis, there is evidence that it plays a role in biochemical recurrence and cancer-specific mortality. Bladder-smoking is strongly associated with bladder cancer, likely due to DNA damage from the release of carcinogenic compounds. Additionally, smoking has been linked to increased cancer-specific mortality and higher risk of tumor recurrence. Renal-smoking tobacco has been associated with tumorigenesis, higher tumor grade and stage, poorer mortality rates, and a greater risk of tumor recurrence. UTUC-tumorigenesis has been associated with smoking tobacco. Additionally, more advanced disease, higher stage, lymph node metastases, poorer survival outcomes, and tumor recurrence have been linked to smoking. CONCLUSION: Smoking has been shown to significantly affect most urologic cancers and has been associated with more aggressive disease, poorer outcomes, and tumor recurrence. The role of smoking cessation is still unclear, but appears to provide some protective effect. Urologists have an opportunity to engage in primary prevention by encouraging cessation practices.

Untargeted Metabolomics to Characterize the Urinary Chemical Landscape of E-Cigarette Users.

The health and safety of using e-cigarette products (vaping) have been challenging to assess and further regulate due to their complexity. Inhaled e-cigarette aerosols contain chemicals with under-recognized toxicological profiles, which could influence endogenous processes once inhaled. We urgently need more understanding on the metabolic effects of e-cigarette exposure and how they compare to combustible cigarettes. To date, the metabolic landscape of inhaled e-cigarette aerosols, including chemicals originated from vaping and perturbed endogenous metabolites in vapers, is poorly characterized. To better understand the metabolic landscape and potential health consequences of vaping, we applied liquid chromatography-mass spectrometry (LC-MS) based nontargeted metabolomics to analyze compounds in the urine of vapers, cigarette smokers, and nonusers. Urine from vapers (n = 34), smokers (n = 38), and nonusers (n = 45) was collected for verified LC-HRMS nontargeted chemical analysis. The altered features (839, 396, and 426 when compared smoker and control, vaper and control, and smoker and vaper, respectively) among exposure groups were deciphered for their structural identities, chemical similarities, and biochemical relationships. Chemicals originating from e-cigarettes and altered endogenous metabolites were characterized. There were similar levels of nicotine biomarkers of exposure among vapers and smokers. Vapers had higher urinary levels of diethyl phthalate and flavoring agents (e.g., delta-decalactone). The metabolic profiles featured clusters of acylcarnitines and fatty acid derivatives. More consistent trends of elevated acylcarnitines and acylglycines in vapers were observed, which may suggest higher lipid peroxidation. Our approach in monitoring shifts of the urinary chemical landscape captured distinctive alterations resulting from vaping. Our results suggest similar nicotine metabolites in vapers and cigarette smokers. Acylcarnitines are biomarkers of inflammatory status and fatty acid oxidation, which were dysregulated in vapers. With higher lipid peroxidation, radical-forming flavoring, and higher level of specific nitrosamine, we observed a trend of elevated cancer-related biomarkers in vapers as well. Together, these data present a comprehensive profiling of urinary biochemicals that were dysregulated due to vaping.

Association of smoking history on health-related quality of life in patients undergoing radical cystecomy.

PURPOSE: Radical cystectomy (RC) has the potential to impact health-related quality of life (HRQOL). Many patients who undergo RC are current or former smokers. To better inform preoperative patient counseling, we examined the association between smoking status and HRQOL after RC. MATERIALS AND METHODS: A secondary analysis was performed on a prospective, longitudinal study (2008-2014) examining HRQOL in patients undergoing RC for bladder cancer. We analyzed 12 validated patient-reported outcome measures that focused on functional, symptomatic, psychosocial, and global HRQOL domains. Measures were collected pre-operatively and 3-, 6-, 12-, 18-, and 24-months postoperatively. For each HRQOL domain, we estimated the mean domain scores using a generalized estimation equation linear regression model. Each model included survey time, smoking status, and time-smoking interaction as covariates. Pairwise comparisons of current, former, and never smokers were estimated from the models. RESULTS: Of the 411 patients available for analysis, 29% (n = 119) never smoked, 59% (n = 244) were former smokers, and 12% (n = 48) were current smokers. Over the follow-up period, never smokers compared to current smokers had better global QOL scores (mean difference = +8.9; 95% CI 1.3-16; p = 0.023) and lower pain levels (mean difference = -10; 95% CI -19 to -0.54; p = 0.036). Compared to current smokers, former smokers had marginal improvements in global QOL (+6.9 points) and pain (-7.5 points) during the follow-up period. CONCLUSIONS: Current smokers reported worse HRQOL recovery in the 24-months after RC. These findings can be used to counsel patients who smoke on recovery expectations.

Integrating Tobacco Treatment Into Oncology Care: Reach and Effectiveness of Evidence-Based Tobacco Treatment Across National Cancer Institute-Designated Cancer Centers.

PURPOSE: Quitting smoking improves patients' clinical outcomes, yet smoking is not commonly addressed as part of cancer care. The Cancer Center Cessation Initiative (C3I) supports National Cancer Institute-designated cancer centers to integrate tobacco treatment programs (TTPs) into routine cancer care. C3I centers vary in size, implementation strategies used, and treatment approaches. We examined associations of these contextual factors with treatment reach and smoking cessation effectiveness. METHODS: This cross-sectional study used survey data from 28 C3I centers that reported tobacco treatment data during the first 6 months of 2021. Primary outcomes of interest were treatment reach (reach)-the proportion of patients identified as currently smoking who received at least one evidence-based tobacco treatment component (eg, counseling and pharmacotherapy)-and smoking cessation effectiveness (effectiveness)-the proportion of patients reporting 7-day point prevalence abstinence at 6-month follow-up. Center-level differences in reach and effectiveness were examined by center characteristics, implementation strategies, and tobacco treatment components. RESULTS: Of the total 692,662 unique patients seen, 44,437 reported current smoking. Across centers, a median of 96% of patients were screened for tobacco use, median smoking prevalence was 7.4%, median reach was 15.4%, and median effectiveness was 18.4%. Center-level characteristics associated with higher reach included higher smoking prevalence, use of center-wide TTP, and lower patient-to-tobacco treatment specialist ratio. Higher effectiveness was observed at centers that served a larger overall population and population of patients who smoke, reported a higher smoking prevalence, and/or offered electronic health record referrals via a closed-loop system. CONCLUSION: Whole-center TTP implementation among inpatients and outpatients, and increasing staff-to-patient ratios may improve TTP reach. Designating personnel with tobacco treatment expertise and resources to increase tobacco treatment dose or intensity may improve smoking cessation effectiveness.
