Predictors of high-intensity care at the end of life among older adults with solid tumors: A population-based study.

INTRODUCTION: High-intensity end-of-life (EoL) care can be burdensome for patients, caregivers, and health systems and does not confer any meaningful clinical benefit. Yet, there are significant knowledge gaps regarding the predictors of high-intensity EoL care. In this study, we identify risk factors associated with high-intensity EoL care among older adults with the four most common malignancies, including breast, prostate, lung, and colorectal cancer. MATERIALS AND METHODS: Using SEER-Medicare data, we conducted a retrospective analysis of Medicare beneficiaries aged 65 and older who died of breast, prostate, lung, or colorectal cancer between 2011 and 2015. We used multivariable logistic regression to identify clinical, demographic, socioeconomic, and geographic predictors of high-intensity EoL care, which we defined as death in an acute care hospital, receipt of any oral or parenteral chemotherapy within 14 days of death, one or more admissions to the intensive care unit within 30 days of death, two or more emergency department visits within 30 days of death, or two or more inpatient admissions within 30 days of death. RESULTS: Among 59,355 decedents, factors associated with increased likelihood of receiving high-intensity EoL care were increased comorbidity burden (odds ratio [OR]:1.29; 95% confidence interval [CI]:1.28-1.30), female sex (OR:1.05; 95% CI:1.01-1.09), Black race (OR:1.14; 95% CI:1.07-1.23), Other race/ethnicity (OR:1.20; 95% CI:1.10-1.30), stage III disease (OR:1.11; 95% CI:1.05-1.18), living in a county with >1,000,000 people (OR:1.23; 95% CI:1.16-1.31), living in a census tract with 10%-<20% poverty (OR:1.09; 95% CI:1.03-1.16) or 20%-100% poverty (OR:1.12; 95% CI:1.04-1.19), and having state-subsidized Medicare premiums (OR:1.18; 95% CI:1.12-1.24). The risk of high-intensity EoL care was lower among patients who were older (OR:0.98; 95% CI:0.98-0.99), lived in the Midwest (OR:0.69; 95% CI:0.65-0.75), South (OR:0.70; 95% CI:0.65-0.74), or West (OR:0.81; 95% CI:0.77-0.86), lived in mostly rural areas (OR:0.92; 95% CI:0.86-1.00), and had poor performance status (OR:0.26; 95% CI:0.25-0.28). Results were largely consistent across cancer types. DISCUSSION: The risk factors identified in our study can inform the development of new interventions for patients with cancer who are likely to receive high-intensity EoL care. Health systems should consider incorporating these risk factors into decision-support tools to assist clinicians in identifying which patients should be referred to hospice and palliative care.

Primary Palliative Care in Urology: Quality Improvement Summit 2021-2022.

INTRODUCTION: The AUA convened a 2021-2022 Quality Improvement Summit to bring together interdisciplinary providers to inform the current state and to discuss potential strategies for integrating primary palliative care into urology practice. We hypothesized that the Summit findings would inform a scalable primary palliative care model for urology. METHODS: The 3-part summit reached a total of 160 interdisciplinary health care professionals. Webinar 1, "Building a Primary Palliative Care Model for Urology," focused on a urologist's role in palliative care. Webinar 2, "Perspectives on Increasing the Use of Palliative Care in Advanced Urologic Disease," addressed barriers to possible implementation of a primary palliative care model. The in-person Summit, "Laying the Foundation for Primary Palliative Care in Urology," focused on operationalization of primary palliative care, clinical innovations needed, and relevant metrics. RESULTS: Participants agreed that palliative care is needed early in the disease course for patients with advanced disease, including those with benign and malignant conditions. The group agreed about the important domains that should be addressed as well as the interdisciplinary providers who are best suited to address each domain. There was consensus that a primary "quarterback" was needed, encapsulated in a conceptual model-UroPal-with a urologist at the hub of care. CONCLUSIONS: The Summit provides the field of urology with a framework and specific steps that can be taken to move urology-palliative care integration forward. Urologists are uniquely positioned to provide primary palliative care for their many patients with serious illness, both in the surgical and chronic care contexts.

Risk Factors for Relapse in Nonseminomatous Testicular Cancer After Postchemotherapy Retroperitoneal Lymph Node Dissection With Viable Residual Cancer.

PURPOSE: No consensus exists on the management of men with nonseminoma and viable nonteratomatous germ cell tumor in the postchemotherapy retroperitoneal lymph node dissection (pcRPLND) specimen after first-line chemotherapy. We analyzed surveillance versus different adjuvant chemotherapy regimens and the influence of time to pcRPLND on oncologic outcomes. METHODS: Data on 117 men treated with cisplatin-based first-line chemotherapy between 1990 and 2018 were collected from 13 institutions. All patients had viable nonteratomatous germ cell tumor in the pcRPLND specimen. Surgery was performed after a median of 57 days, followed by either surveillance (n = 64) or adjuvant chemotherapy (n = 53). Primary end points were progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS). RESULTS: After controlling for International Germ Cell Cancer Cooperative Group risk group and percent of viable malignant cells found at RPLND, no difference was observed between men managed with surveillance or adjuvant chemotherapy regarding PFS (hazard ratio [HR], 0.72 [95% CI, 0.32 to 1.6]; P = .4), CSS (HR, 0.69; 95% CI, 0.20 to 2.39; P = .6), and OS (HR, 0.78 [95% CI, 0.25 to 2.44]; P = .7). No statistically significant differences for PFS, CSS, or OS were observed on the basis of chemotherapy regimen or in men treated with pcRPLND ≤57 versus >57 days after first-line chemotherapy. Residual disease with <10% versus ≥10% viable cancer cells were associated with a longer PFS (HR, 3.22 [95% CI, 1.29 to 8]; P = .012). Relapse in the retroperitoneum was observed in 34 (29%) men. CONCLUSION: Men with a complete resection at pcRPLND and <10% viable cells have favorable outcomes without further treatment. Complete retroperitoneal resection seems more important than early pcRPLND.

Predicting Limited Survival Following Inguinal Lymph Node Dissection in Penile Cancer: Should We Revisit the Goals of Care?

OBJECTIVE: Patients with advanced penile squamous cell cancer have a poor prognosis and can benefit from early palliative care consultation. We built a model to identify those patients most likely to benefit. METHODS: Patients with penile squamous cell cancer undergoing inguinal lymph node dissection were identified from the National Cancer Database (NCDB) and a multi-institutional international dataset (INT). A multivariable Cox proportional hazards model for overall survival (OS) was developed using the NCDB and applied to the INT dataset. Parameters were used to make receiver operating characteristic (ROC) curves. ROC-related criteria were optimized to identify a predictive probability cut point and dichotomize patients from INT into risk groups for limited OS of <6 and <12 months. RESULTS: NCDB had 860 deaths; 105 (5%) at 6 months and 296 (15%) at 12 months. INT had 257 deaths; 56 (8%) at 6 months and 124 (18%) at 12 months. Limited OS was associated with older age, greater T and N stage, and fewer lymph nodes removed. Optimized ROC criteria using the OS <6 months curve best dichotomized INT patients into high-risk group with median OS of 24 months (95% CI 18-34) and low-risk group with median OS of 174 months (95% CI 120-NE). CONCLUSION: We developed a simple model that could be used as a screening tool for early palliative care referral.

Exploring knowledge, perspectives, and misperceptions of palliative care: A mixed methods analysis.

OBJECTIVES: To better understand palliative care knowledge and beliefs of patients with stage II or greater bladder cancer and their caregivers. SUBJECTS AND METHODS: Participants were primarily patients diagnosed with muscle-invasive or locally advanced bladder cancer. All were encouraged to enroll with a caregiver (defined as the individual who most closely assists with a patient's care). Participants completed a survey and semistructured interview. Applied thematic analysis techniques were used to analyze the interview data. In total, we recruited 16 dyads, 11 patients who participated alone, and 1 caregiver who participated alone. RESULTS: Patients and caregivers had high levels of palliative care knowledge and there was no difference in baseline knowledge. Palliative care receptivity was also high, with most participants stating that they would be "very likely" to consider palliative care for themselves or a loved one. However, based on the analysis of multiple-choice palliative care questions and interview transcripts, many participants lacked a nuanced understanding of palliative care and harbored many common misconceptions of the basic tenants. Five main themes emerged related to palliative care: (1) Participants have a general lack of awareness of it, (2) Participants associate it with hospice and death, (3) Participants view it as primarily emotional or psychological support, (4) Participants believe it is for patients without a strong support system, and (5) Participants believe it is for people who have "given up." CONCLUSIONS: High educational attainment and baseline palliative care knowledge did not preclude the most common misperceptions related to palliative care. These study results indicate that patients need clearer counseling regarding the definition, goals, benefits, and availability of palliative care.

Palliative care knowledge, attitudes, and experiences amongst patients with bladder cancer and their caregivers.

OBJECTIVES: Palliative care is underutilized amongst patients with bladder cancer despite guideline recommendations and known benefits. In order to uncover potential access barriers, we sought to describe patient and caregiver knowledge, attitudes and experiences surrounding palliative care. METHODS: We surveyed 272 patients with bladder cancer and their caregivers through the Bladder Cancer Advocacy Network Patient Survey Network. In addition to collecting demographic, socioeconomic, and clinical characteristics, previously studied and validated questionnaires on palliative care knowledge and beliefs were administered. Patients and caregivers were also queried regarding their experiences with palliative care consultation. RESULTS: Survey respondents demonstrated highly accurate knowledge of palliative care services. Attitudes and beliefs surrounding palliative care were overall positive. Caregivers demonstrated better knowledge and more positive beliefs of palliative care compared to patients. Despite an overall positive sentiment toward palliative care, only 9% of the cohort had palliative care consultation as part of their cancer treatment plan. Most patients with muscle-invasive or metastatic bladder cancer wished that palliative care had been discussed by their providers. CONCLUSIONS: A subset of bladder cancer patients possess accurate knowledge and positive beliefs of palliative care. Palliative care is infrequently discussed during the treatment of bladder cancer, with patients and their caregivers expressing desire for palliative care to be discussed more often. Provider education surrounding palliative care services is imperative to improving access for bladder cancer patients and caregivers.

New Mental Health Diagnosis as a Prognostic Factor for Muscle-Invasive Bladder Cancer.

BACKGROUND: To examine differences in survival outcomes for muscle-invasive bladder cancer patients stratified by new mental health diagnosis. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER)-Medicare data, we identified patients diagnosed with muscle-invasive bladder cancer between 2008 and 2014. Our primary outcome was cancer-specific and overall hazards of mortality. As a secondary outcome, we reported predictors of developing a new mental health diagnosis after bladder cancer diagnosis. We used Cox proportional hazards models to determine the impact of palliative care and mental health diagnoses on survival outcomes after adjusting for grade, stage, comorbidity index, and baseline demographics. RESULTS: Of the 3794 patients who met inclusion criteria, 1193 (31%) were diagnosed with a mental health illness after their bladder cancer diagnosis during the 6 years in the study period. The most common diagnoses were depression (13%), alcohol and drug abuse (12%), and anxiety (11%). Patients with a post-bladder cancer mental health diagnosis had a 57% higher hazard of overall mortality (HR 1.57, P = .048) and an 80% higher hazard of bladder cancer-specific mortality (HR 1.81, P = .037) CONCLUSIONS: New mental health diagnoses are associated with worse survival in patients with muscle invasive bladder cancer. This suggests that a multimodal approach to bladder cancer treatment should include addressing the non-oncologic needs of the patient to optimize survival outcomes.

Survival Outcomes Associated With Cytoreductive Nephrectomy in Patients With Metastatic Clear Cell Renal Cell Carcinoma.

Importance: Level I evidence has failed to demonstrate an overall survival (OS) advantage for cytoreductive nephrectomy in patients with metastatic clear cell renal cell carcinoma (ccRCC) in the modern era, which is at odds with observational studies reporting a marked OS benefit associated with these operations. These observational studies were not designed to adjust for unmeasured confounding. Objective: To assess whether cytoreductive nephrectomy is associated with improved OS in patients with metastatic ccRCC. Design, Setting, and Participants: This cohort study identified patients with metastatic ccRCC in the National Cancer Database from January 1, 2006, to December 31, 2016, who received systemic targeted therapy. The analysis was finalized on July 23, 2021. Exposures: Receipt of cytoreductive nephrectomy. Main Outcomes and Measures: The primary outcome was OS from the date of diagnosis to death or censoring at last follow-up. Distance from the patients' zip code of residence to the treating facility was identified as a valid instrument and was used in a 2-stage residual inclusion instrumental variable analysis. Conventional adjustments for selection bias, multivariable Cox proportional hazards regression, and propensity score matching were performed for comparison. Measured covariates adjusted for in all analyses included age, sex, race, Charlson-Deyo score, facility type, year of diagnosis, clinical T stage, and clinical N stage. Results: The final study population included 12 766 patients (median age, 63 years; IQR, 56-70 years; 8744 [68%] male; 11 206 [88%] White). Cytoreductive nephrectomy was performed in 5005 patients (39%). Conventional adjustments for selection bias demonstrated a significant OS benefit associated with cytoreductive nephrectomy (multivariable Cox proportional hazards regression: hazard ratio [HR], 0.49; 95% CI, 0.47-0.51; propensity score matching: HR, 0.48; 95% CI, 0.46-0.50). Instrumental variable estimates did not demonstrate an association between cytoreductive nephrectomy and OS (HR, 0.92; 95% CI, 0.78-1.09). Conclusions and Relevance: Instrumental variable analysis did not demonstrate a survival advantage associated with cytoreductive nephrectomy for patients with metastatic ccRCC. This discrepancy likely reflects the fact that surgical indication for cytoreductive nephrectomy is primarily driven by factors that are not commonly measured or available in observational data sets.

Is There a Role for Palliative Services and Supportive Care in Managing Advanced Penile Cancer?

OBJECTIVES: We aim to review the benefits of palliative care, describe why a palliative approach to care is needed for patients with advanced penile squamous cell carcinoma and propose ways in which oncology nurses can improve access to and provision of palliative care. DATA SOURCES: A review of the literature was performed and identified a range of randomized trials and systematic reviews regarding the benefits of palliative care in this patient group. Cohort studies of patients with penile cancer were used to describe the psychosocial and physical disease burden of penile cancer. CONCLUSION: Throughout each phase of penile cancer and its treatment, oncology nurses can engage in care that goes beyond cancer-directed treatments to address the whole person, thereby improving quality of life by delivering person-centered palliative care in line with individual needs. IMPLICATIONS FOR NURSING PRACTICE: Oncology nurses are in key positions to explore many concerns that patients with penile cancer have for themselves or their caregivers. Through speaking directly with patients and caregivers, oncology nurses can uncover sources of distress, assess for unmet needs, and advocate for improved primary palliative care or early referral to specialty palliative care teams.

Minimally invasive retroperitoneal lymph node dissection for men with testis cancer: a retrospective cohort study of safety and feasibility.

PURPOSE: To describe the perioperative safety, functional and immediate post-operative oncological outcomes of minimally invasive RPLND (miRPLND) for testis cancer. METHODS: We performed a retrospective multi-centre cohort study on testis cancer patients treated with miRPLND from 16 institutions in eight countries. We measured clinician-reported outcomes stratified by indication. We performed logistic regression to identify predictors for maintained postoperative ejaculatory function. RESULTS: Data for 457 men undergoing miRPLND were studied. miRPLND comprised laparoscopic (n = 56) or robotic (n = 401) miRPLND. Indications included pre-chemotherapy in 305 and post-chemotherapy in 152 men. The median retroperitoneal mass size was 32 mm and operative time 270 min. Intraoperative complications occurred in 20 (4%) and postoperative complications in 26 (6%). In multivariable regression, nerve sparing, and template resection improved ejaculatory function significantly (template vs bilateral resection [odds ratio (OR) 19.4, 95% confidence interval (CI) 6.5-75.6], nerve sparing vs non-nerve sparing [OR 5.9, 95% CI 2.3-16.1]). In 91 men treated with primary RPLND, nerve sparing and template resection, normal postoperative ejaculation was reported in 96%. During a median follow-up of 33 months, relapse was detected in 39 (9%) of which one with port site (< 1%), one with peritoneal recurrence and 10 (2%) with retroperitoneum recurrences. CONCLUSION: The low proportion of complications or peritoneal recurrences and high proportion of men with normal postoperative ejaculatory function supports further miRPLND studies.

Comparative effectiveness analysis of first-line immunotherapy versus chemotherapy in metastatic urothelial carcinoma of the bladder.

BACKGROUND: Clinical trials have not shown a significant overall survival (OS) difference between chemotherapy and immunotherapy as first-line agents in metastatic urothelial carcinoma (UC). However, the generalizability of these findings in a real-world setting has not yet been evaluated in comparative effectiveness studies. OBJECTIVE: To assess the effectiveness of first-line immunotherapy compared with chemotherapy regimens on OS in patients with metastatic UC of the bladder. DESIGN, SETTING, AND PARTICIPANTS: This retrospective propensity-matched study identified metastatic bladder UC patients in the National Cancer Database from 2014 to 2017 who received either first-line immunotherapy-monotherapy or multi-agent chemotherapy, and who were not treated on a clinical trial protocol. OUTCOME MEASURES AND ANALYSIS: The primary outcome was OS from the date of diagnosis to date of death or censoring at last follow-up. Patients were stratified into first-line immunotherapy and chemotherapy treatment groups. After 1:1 nearest-neighbor caliper-matching of propensity scores, the survival analysis was conducted using Cox regression modeling and Kaplan-Meier estimates. RESULTS AND LIMITATIONS: A total of 2,796 patients were included in the final study population, and 960 in the matched cohort (480 per treatment group). Utilization of immunotherapy increased over the time period studied as chemotherapy decreased (Immunotherapy: 3%-37%; Chemotherapy: 97%-63%; P < 0.001). In the overall cohort, patients who received first-line immunotherapy were older and more comorbid than those who received first-line chemotherapy (Age: 73 v. 67, respectively, P < 0.001; Charlson-Deyo score ≥2: 17% v. 11.5%, respectively, P < 0.001). In the matched cohort, patients who were treated with first-line immunotherapy had similar OS to those who were treated with first-line chemotherapy (HR: 0.91, 95CI 0.72-1.15). Due to the retrospective nature of the study, interpretation is limited by potential selection bias from unmeasured confounding. CONCLUSIONS AND RELEVANCE: Metastatic bladder UC patients who received first-line immunotherapy had similar OS to those who received first-line chemotherapy.

Incorporating palliative care principles to improve patient care and quality of life in urologic oncology.

Palliative care - specialized healthcare focused on improving quality of life for patients with serious illnesses - can help urologists to care for patients with unmet symptom, coping and communication needs. Society guidelines from the American Society of Clinical Oncology and the National Comprehensive Cancer Network recommend incorporating palliative care into standard oncological care, based on multiple randomized trials demonstrating that it significantly improves physical well-being, patient satisfaction and goal concordant care. Misconceptions regarding the objective and ideal timing of palliative care are common; a key concept is that palliative care and treatments seeking to cure or prolong life are not mutually exclusive. Urologists are well positioned to champion the integration of palliative care into surgical urologic oncology and should be aware of palliative care guidelines, indications for palliative care use and how the field of urologic oncology can adopt best practices.

Pathological Downstaging and Survival Outcomes Associated with Neoadjuvant Chemotherapy for Variant Histology Muscle Invasive Bladder Cancer.

PURPOSE: Patients with muscle invasive bladder cancer (MIBC) of variant histology have a poor prognosis. It is unclear if neoadjuvant chemotherapy prior to radical cystectomy is associated with pathological downstaging or improved overall survival (OS) for patients with variant histology. Our objective was to assess for associations between receipt of neoadjuvant chemotherapy, pathological downstaging and OS for patients with variant histology MIBC. MATERIALS AND METHODS: Patients were identified in the National Cancer Database from 2004 to 2017 with MIBC, without metastases, who underwent radical cystectomy. Patients were stratified by histological subgroup, and receipt or nonreceipt of neoadjuvant chemotherapy. Pathological downstaging was defined as pT0N0 or pT ≤1N0, and OS from the time of diagnosis to date of death or censoring at last followup. Multivariable logistic regression analysis determined associations between neoadjuvant chemotherapy and pathological downstaging. Multivariable Cox regression analysis determined associations between neoadjuvant chemotherapy and OS. RESULTS: A total of 31,218 patients were included in the final study population (urothelial carcinoma [UC]: 27,779; sarcomatoid UC: 501; micropapillary UC: 418; squamous cell carcinoma: 1,141; neuroendocrine carcinoma: 629; adenocarcinoma: 750). Neoadjuvant chemotherapy was associated with pathological downstaging to pT0N0 in all histological subgroups (UC: OR 5.1 [4.6-5.6]; sarcomatoid UC: OR 13.8 [5.5-39.0]; micropapillary UC: OR 9.7 [2.8-46.8]; squamous cell carcinoma: OR 7.4 [2.1-24.5]; neuroendocrine: OR 4.7 [2.6-9.2]; adenocarcinoma: OR 23.3 [8.0-74.2]). Neoadjuvant chemotherapy was associated with improved OS for UC (HR 0.8 [0.77-0.84]), sarcomatoid UC (HR 0.64 [0.44-0.91]) and neuroendocrine carcinoma (HR 0.55 [0.43-0.70]). CONCLUSIONS: Neoadjuvant chemotherapy was associated with pathological downstaging for all MIBC histological variants, with improved OS for patients with UC, sarcomatoid variant UC and neuroendocrine carcinoma.

Real-World Survival Outcomes Associated With First-Line Immunotherapy, Targeted Therapy, and Combination Therapy for Metastatic Clear Cell Renal Cell Carcinoma.

Importance: Clinical trials have shown an overall survival (OS) benefit associated with first-line immunotherapy (IT) and combination targeted therapy (TT) and IT regimens compared with TT among patients with metastatic clear cell renal cell carcinoma (RCC). Generalizability of these findings in a real-world cohort outside of a clinical trial setting is unclear. Objective: To assess the association of first-line TT, IT, and combination TT and IT regimens with OS in a real-world cohort of patients with metastatic clear cell RCC. Design, Setting, and Participants: This retrospective propensity-matched cohort study identified 5872 patients with metastatic clear cell RCC in the National Cancer Database from January 1, 2015, to December 31, 2017, who received first-line TT, IT, or combination TT and IT and were not treated on a clinical trial protocol. Patients were stratified by first-line systemic treatment. Statistical analysis was conducted from October 1 to December 1, 2020. Main Outcomes and Measures: The primary outcome was OS from the date of diagnosis to death or censoring at last follow-up. After 1:1:1 nearest-neighbor caliper matching of propensity scores, survival analyses were conducted using Cox proportional hazards regression and Kaplan-Meier estimates. Results: The final study population included 5872 patients (TT group: n = 4755 [81%]; 3332 men [70%]; median age, 64 years [interquartile range, 57-71 years]; IT group: n = 638 [11%]; 475 men [74%]; median age, 61 years [interquartile range, 54-69 years]; and combination TT and IT group: n = 479 [8%]; 321 men [67%]; median age, 62 years [interquartile range, 55-69 years]), and the matched cohort included 1437 patients (479 per treatment group). Patients in the IT and combination TT and IT groups were younger than those in the TT group, had fewer comorbid conditions (Charlson-Deyo score of 0, 480 of 638 [75%] in the TT group, 356 of 479 [74%] in the IT group, and 3273 of 4755 [69%] in the combination TT and IT group), and were more often treated at academic centers (315 of 638 [49%], 216 of 479 [45%], and 1935 of 4755 [41%], respectively). Both first-line IT and combination TT and IT were associated with improved OS compared with first-line TT for patients with metastatic clear cell RCC (IT group: hazard ratio [HR], 0.60 [95% CI, 0.48-0.75]; P < .001; combination TT and IT group: HR, 0.74 [95% CI, 0.60-0.91]; P = .005). No survival difference was seen between the IT and combination TT and IT groups (combination TT and IT: HR, 1.24 [95% CI, 0.98-1.56]; P = .08). Conclusions and Relevance: This study suggests that both first-line IT and combination TT and IT were associated with improved OS compared with first-line TT for patients with metastatic clear cell RCC. These findings are similar to those identified in recently reported clinical trials, lending confidence to the broader applicability of these findings outside of a clinical trial setting.

High-intensity end-of-life care among Medicare beneficiaries with bladder cancer.

OBJECTIVES: To quantify the proportion of patients receiving high-intensity end-of-life care, identify associated risk factors, and assess how receipt of palliative care impact end-of-life care; as the delivery of such care, and how it relates to palliative care, has not been reported in bladder cancer SUBJECTS AND METHODS: We conducted a retrospective cohort study of patients with bladder cancer who died within 1 year of diagnosis using Surveillance, Epidemiology, and End Results linked Medicare data. The primary outcome was a composite measure of high-intensity end-of-life care (>1 hospital admission, >1 ED visit, or ≥1 ICU admission within the last month of life; receipt of chemotherapy within the last 2 weeks of life; or acute care in-hospital death). Secondary outcomes included the use of such care over time and any association with the use of palliative care. A generalized linear mixed model assessed for independent determinants. RESULTS: Overall, 45% of patients received high-intensity end-of-life care. This proportion decreased over time. Patients receiving high-intensity care had higher rates of comorbidities, advanced bladder cancer, and nonbladder cancer cause of death. These patients more often received palliative care but, compared to those not receiving high-intensity care, this occurred farther removed from bladder cancer diagnosis and closer to death. CONCLUSIONS: Nearly half of Medicare beneficiaries with bladder cancer who die within 1 year of diagnosis receive high-intensity care at the end of life. Palliative care was seldom used and only very near the time of death.

Immunotherapy in Bacillus Calmette-Guerin (BCG) unresponsive nonmuscle invasive bladder cancer.

PURPOSE OF REVIEW: A number of promising therapies for Bacillus Calmette-Guerin (BCG) unresponsive nonmuscle invasive bladder cancer (NMIBC) are in the pipeline. In this review, we discuss the history of immunotherapy for the treatment of NMIBC and future developments, focusing on novel intravesical treatments. RECENT FINDINGS: The term BCG unresponsive NMIBC encompasses patients with both BCG refractory and BCG relapsing disease. This definition was adopted to standardize inclusion criteria for patients enrolling in clinical trials in this setting. A host of intravesical immuno-oncologic therapies that include gene therapies, oncolytic viruses, cell surface molecule delivered immunotoxins, and cytokine driven agonism of cellular immunity, are in various phases of the drug development pipeline. In addition, pembrolizumab, an immune-checkpoint inhibitor, has recently been approved as a treatment option for BCG unresponsive NMIBC. SUMMARY: Patients with BCG unresponsive disease face many difficulties. Although radical cystectomy is the most effective treatment option for these patients, it is associated with significant morbidity, difficult recovery challenges, and refusal by many patients. Cancer immunotherapies may provide bladder sparing options for some patients who develop BCG unresponsive disease.

Resurrecting immortal-time bias in the study of readmissions.

OBJECTIVE: To compare readmission rates as measured by the Centers for Medicare and Medicaid Services and the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) methods. DATA SOURCES: 20 percent sample of national Medicare data for patients undergoing cystectomy, colectomy, abdominal aortic aneurysm (AAA) repair, and total knee arthroplasty (TKA) between 2010 and 2014. STUDY DESIGN: Retrospective cohort study comparing 30-day readmission rates. DATA COLLECTION/EXTRACTION METHODS: Patients undergoing cystectomy, colectomy, abdominal aortic aneurysm repair, and total knee arthroplasty between 2010 and 2014 were identified. PRINCIPAL FINDINGS: Cystectomy had the highest and total knee arthroplasty had the lowest readmission rate. The NSQIP measure reported significantly lower rates for all procedures compared to the CMS measure, which reflects an immortal-time bias. CONCLUSIONS: We found significantly different readmission rates across all surgical procedures when comparing CMS and NSQIP measures. Longer length of stay exacerbated these differences. Uniform outcome measures are needed to eliminate ambiguity and synergize research and policy efforts.

Trends in renal calculus composition and 24-hour urine analyses in patients with neurologically derived musculoskeletal deficiencies

ABSTRACT Purpose: To better characterize metabolic stone risk in patients with neurologically derived musculoskeletal deficiencies (NDMD) by determining how patient characteristics relate to renal calculus composition and 24-hour urine parameters. Materials and Methods: We performed a retrospective cohort study of adult patients with neurologically derived musculoskeletal deficiencies presenting to our multidisciplinary Kidney Stone Clinic. Patients with a diagnosis of NDMD, at least one 24-hour urine collection, and one chemical stone analysis were included in the analysis. Calculi were classified as primarily metabolic or elevated pH. We assessed in clinical factors, demographics, and urine metabolites for differences between patients who formed primarily metabolic or elevated pH stones. Results: Over a 16-year period, 100 patients with NDMD and nephrolithiasis were identified and 41 met inclusion criteria. Thirty percent (12 / 41) of patients had purely metabolic calculi. Patients with metabolic calculi were significantly more likely to be obese (median body mass index 30.3kg / m2 versus 25.9kg / m2), void spontaneously (75% vs. 6.9%), and have low urine volumes (100% vs. 69%). Patients who formed elevated pH stones were more likely to have positive preoperative urine cultures with urease splitting organisms (58.6% vs. 16.7%) and be hyperoxaluric and hypocitraturic on 24-hour urine analysis (37mg / day and 265mg / day versus 29mg / day and 523mg / day). Conclusions: Among patients with NDMD, metabolic factors may play a more significant role in renal calculus formation than previously believed. There is still a high incidence of carbonate apatite calculi, which could be attributed to bacteriuria. However, obesity, low urine volumes, hypocitraturia, and hyperoxaluria suggest an underrecognized metabolic contribution to stone formation in this population.
