"Triple Threat" Conditions Predict Mortality Among Patients With Advanced Cancer Who Present to the Emergency Department.

BACKGROUND: Delirium, poor performance status, and dyspnea predict short survival in the palliative care setting. OBJECTIVE: Our goal was to determine whether these three conditions, which we refer to as a "triple threat," also predict mortality among patients with advanced cancers in the emergency department (ED). METHODS: The study sample included 243 randomly selected, clinically stable patients with advanced cancer who presented to our ED. The analysis included patients who had delirium (Memorial Delirium Assessment Scale score ≥ 7), poor performance status (Eastern Cooperative Oncology Group performance status score of 3 or 4), or dyspnea as a presenting symptom. We obtained survival data from medical records. We calculated predicted probability of dying within 30 days and association with number of symptoms after the ED visit using logistic regression analysis. RESULTS: Twenty-eight patients died within 30 days after presenting to the ED. Death within 30 days occurred in 36% (16 of 44) of patients with delirium, 28% (17 of 61) of patients with poor performance status, and 14% (7 of 50) of patients with dyspnea, with a predicted probability of 30-day mortality of 0.38 (95% confidence interval [CI] 0.25-0.53), 0.28 (95% CI 0.18-0.40), and 0.15 (95% CI 0.07-0.29), respectively. The predicted probability of death within 30 days for patients with two or three of the conditions was 0.49 (95% CI 0.34-0.66) vs. 0.05 (95% CI 0.02-0.09) for patients with none or one of the conditions. CONCLUSIONS: Patients with advanced cancers who present to the ED and have at least two triple threat conditions have a high probability of death within 30 days.

Development and validation of a risk assessment tool for BKPyV Replication in allogeneic stem cell transplant recipients.

BACKGROUND: BK polymavirus (BKPyV), a member of the family Polyomaviridae, is associated with increased morbidity and mortality in allogeneic stem cell transplant recipients. METHODS: In our previous retrospective study of 2477 stem cell transplant patients, BKPyV replication independently predicted chronic kidney disease and poor survival. In this study, using the same cohort, we derived and validated a risk grading system to identify patients at risk of BKPyV replication after transplantation in a user-friendly modality. We used 3 baseline variables (conditioning regimen, HLA match status, and underlying cancer diagnosis) that significantly predicted BKPyV replication in our initial study in a subdistribution hazard model with death as a competing risk. We also developed a nomogram of the hazard model as a visual aid. The AUC of the ROC of the risk-score-only model was 0.65. We further stratified the patients on the basis of risk score into low-, moderate-, and high-risk groups. RESULTS: The total risk score was significantly associated with BKPyV replication (P < .0001). At 30 days after transplantation, the low-risk (score ≤ 0) patients had a 9% chance of developing symptomatic BKPyV replication, while the high-risk (score ≥ 8) of the population had 56% of developing BKPyV replication. We validated the risk score using a separate cohort of 1478 patients. The AUC of the ROC of the risk-score-only model was 0.59. Both the total risk score and 3-level risk variable were significantly associated with BKPyV replication in this cohort (P < .0001). CONCLUSIONS: This grading system for the risk of symptomatic BKPyV replication may help in early monitoring and intervention to prevent BKPyV-associated morbidity, mortality, and kidney function decline.

Ruxolitinib therapy is associated with improved renal function in patients with primary myelofibrosis.

Recent evidence suggests that renal dysfunction may be a direct consequence of primary myelofibrosis (PMF). We performed a retrospective analysis of 100 patients with previously untreated PMF, receiving frontline treatment with single agent ruxolitinib, and compared them to 105 patients, receiving frontline treatment with a non-ruxolitinib-based therapy, matched by age, sex, DIPSS plus, and estimated glomerular filtration rate (eGFR). Use of ruxolitinib associated with a significantly higher rate of renal improvement (RI) > 10% (73% vs 50%, p = 0.01) confirmed on multivariate analysis (MVA) [odds ratio 3, 95% confidence interval (CI) 1.6-5.5, p < 0.001]. After a median follow-up of 41 months (range, 1-159 months), median failure-free survival (FFS) was 14 months (range, 1-117 months). Achievement of a RI > 10% maintained its independent association with prolonged FFS on MVA (hazard ratio 1.4, 95% CI 1.1-2, p = 0.02). Ruxolitinib can significantly improve renal function in patients with PMF, significantly impacting failure-free survival.

Advance Directives, Hospitalization, and Survival Among Advanced Cancer Patients with Delirium Presenting to the Emergency Department: A Prospective Study.

BACKGROUND: To improve the management of advanced cancer patients with delirium in an emergency department (ED) setting, we compared outcomes between patients with delirium positively diagnosed by both the Confusion Assessment Method (CAM) and Memorial Delirium Assessment Scale (MDAS), or group A (n = 22); by the MDAS only, or group B (n = 22); and by neither CAM nor MDAS, or group C (n = 199). MATERIALS AND METHODS: In an oncologic ED, we assessed 243 randomly selected advanced cancer patients for delirium using the CAM and the MDAS and for presence of advance directives. Outcomes extracted from patients' medical records included hospital and intensive care unit admission rate and overall survival (OS). RESULTS: Hospitalization rates were 82%, 77%, and 49% for groups A, B, and C, respectively (p = .0013). Intensive care unit rates were 18%, 14%, and 2% for groups A, B, and C, respectively (p = .0004). Percentages with advance directives were 52%, 27%, and 43% for groups A, B, and C, respectively (p = .2247). Median OS was 1.23 months (95% confidence interval [CI] 0.46-3.55) for group A, 4.70 months (95% CI 0.89-7.85) for group B, and 10.45 months (95% CI 7.46-14.82) for group C. Overall survival did not differ significantly between groups A and B (p = .6392), but OS in group C exceeded those of the other groups (p < .0001 each). CONCLUSION: Delirium assessed by either CAM or MDAS was associated with worse survival and more hospitalization in patients with advanced cancer in an oncologic ED. Many advanced cancer patients with delirium in ED lack advance directives. Delirium should be assessed regularly and should trigger discussion of goals of care and advance directives. IMPLICATIONS FOR PRACTICE: Delirium is a devastating condition among advanced cancer patients. Early diagnosis in the emergency department (ED) should improve management of this life-threatening condition. However, delirium is frequently missed by ED clinicians, and the outcome of patients with delirium is unknown. This study finds that delirium assessed by the Confusion Assessment Method or the Memorial Delirium Assessment Scale is associated with poor survival and more hospitalization among advanced cancer patients visiting the ED of a major cancer center, many of whom lack advance directives. Therefore, delirium in ED patients with cancer should trigger discussion about advance directives.

Poor immune reconstitution is associated with symptomatic BK polyomavirus viruria in allogeneic stem cell transplant recipients.

BACKGROUND: BK polyomavirus (BKPyV) infections are known indicators of immune suppression in hematopoietic stem cell transplant (HSCT) recipients; they can lead to hemorrhagic cystitis, ureteral stenosis, renal dysfunction, and prolonged hospital stays. In this study, we determined transplant-associated variables and immune parameters that can predict for the risk of BKPyV viruria. We hypothesized that BKPyV infection is a marker of poor immune recovery. METHODS: We analyzed all engrafted patients undergoing first allogeneic HSCT at MD Anderson Cancer Center in Houston between January 2004 and December 2012. We evaluated their immune parameters and their transplant-associated factors. BKPyV positivity was defined as BKPyV detection in urine by polymerase chain reaction testing. Cox proportional hazards model, as well as competing risk analysis method using subdistribution hazard models with death as competing risk, were applied to assess risk of BKPyV viruria. RESULTS: We identified a total of 2477 patients with a median age of 52 years. BKPyV viruria was manifest in 25% (n=629) of the patients. The median time from transplantation to BKPyV viruria development was 42 days among the patients who had BKPyV viruria. On multivariate analysis, tumor type, acute GVHD, chronic GVHD, myeloablative conditioning regimen, cord blood as the graft source, CD3+ , CD4+ , CD8+ , CD56+ , NK counts, and low platelet count were shown to be significantly associated with BKPyV infection. These finding were further confirmed when models incorporating the competing risk of death yielded similar findings. CONCLUSION: In this study, we report significant associations between BKPyV reactivation following allogeneic HSCT and suppressed immune variables. In addition, this study provides valuable information on the immune status of HSCT recipients as a predictor of BKPyV infections that may in turn help us formulate plans for more effective prevention and treatment of this infection.

Delirium frequency among advanced cancer patients presenting to an emergency department: A prospective, randomized, observational study.

BACKGROUND: The frequency of delirium among patients with cancer presenting to the emergency department (ED) is unknown. The purpose of this study was to determine delirium frequency and recognition by ED physicians among patients with advanced cancer presenting to the ED of The University of Texas MD Anderson Cancer Center. METHODS: The study population was a random sample of English-speaking patients with advanced cancer who presented to the ED and met the study criteria. All patients were assessed with the Confusion Assessment Method (CAM) to screen for delirium and with the Memorial Delirium Assessment Scale (MDAS) to measure delirium severity (mild, ≤15; moderate, 16-22; and severe, ≥23). ED physicians were also asked whether their patients were delirious. RESULTS: Twenty-two of the 243 enrolled patients (9%) had CAM-positive delirium, and their median MDAS score was 14 (range, 9-21 [30-point scale]). The median age of the enrolled patients was 62 years (range, 19-89 years). Patients with delirium had a poorer performance status than patients without delirium (P < .001); however, the 2 groups did not differ in other characteristics. Ten of the 99 patients who were 65 years old or older (10%) had CAM-positive delirium, whereas 12 of the 144 patients younger than 65 years (8%) did (P = .6). According to the MDAS scores, delirium was mild in 18 patients (82%) and moderate in 4 patients (18%). Physicians correctly identified delirium in 13 of the CAM-positive delirious patients (59%). CONCLUSIONS: Delirium is relatively frequent and is underdiagnosed by physicians in patients with advanced cancer who are visiting the ED. Further research is needed to identify the optimal screening tool for delirium in ED. Cancer 2016. © 2016 American Cancer Society. Cancer 2016;122:2918-2924. © 2016 American Cancer Society.

Is there coronary artery disease in the cancer patient who manifests with chest pain, shortness of breath and/or tachycardia? A retrospective observational cohort.

OBJECTIVE: Cancer therapies lead to chest pain (CP), shortness of breath (SOB), and/or tachydysrhythmias (TACH Y) requiring cardiac risk stratification including coronary computed tomographic angiography (CCTA). We posit that cancer patients with CP, SOB and/or TACH Y have greater odds of having coronary artery disease (CAD) identified by CCTA than those that do not. METHODS: Eligibility for this IRB-approved retrospective observational cohort included those with cancer that had CCTA performed. Groups were stratified with and without CP, SOB, and/or TACH Y. Electronic medical records were mined for appropriate CPT codes from 01012010 to 08312013. Demographics, cancer type, and clinical outcomes were obtained. Standard t tests, odds ratios, and frequencies were used. RESULTS: Of 176 participants identified; 84 were male (48 %) and 118 were Caucasian (67 %). Of those, 100/176 (57 %) had CP, SOB, and/or TACH Y; 72/100 (72 %) had CP; 10/100 (10 %) had TACH Y; and 18/100 (18 %) had SOB. Of the 72 with CP, 40 (56 %) had CAD; of the 10 with TACH Y, 6 (60 %) had CAD; of the 18 with SOB, and 10 (56 %) had CAD. Thus, a 2.6-fold increased odds of having CAD (56/100 = 56 %) compared to 25/76 (33 %) in the group with cancer without CP, SOB, and/or TACH Y (95 % CI = 1.40 to 4.83; p = 0.003). CONCLUSION: Cancer patients with CP, SOB, and/or TACH Y have a 2.6-fold increased odds of having CAD compared to cancer patients without CP, SOB, and/or TACH Y (95 % CI = 1.40 to 4.83; p = 0.003).

Prior Advanced Care Planning and Outcomes of Cardiopulmonary Resuscitation in the Emergency Department of a Comprehensive Cancer Center.

Cardiopulmonary resuscitation (CPR) outcomes vary for patients with cancer. Here, we characterized cancer patients who underwent CPR in the emergency department (ED), their outcomes, and the effects of advanced care planning (ACP). The hospital databases and electronic medical records of cancer patients at a comprehensive cancer center who underwent CPR in the ED from 6 March 2016 to 31 December 2022 were reviewed for patient characteristics, return of spontaneous circulation (ROSC), conversion to do-not-resuscitate (DNR) status afterward, hospital and intensive care unit (ICU) length of stay, mortality, cost of hospitalization, and prior GOC discussions. CPR occurred in 0.05% of all ED visits. Of the 100 included patients, 67 patients achieved ROSC, with 15% surviving to hospital discharge. The median survival was 26 h, and the 30-day mortality rate was 89%. Patients with and without prior ACP had no significant differences in demographics, metastatic involvement, achievement of ROSC, or in-hospital mortality, but patients with ACP were more likely to change their code status to DNR and had shorter stays in the ICU or hospital. In conclusion, few cancer patients undergo CPR in the ED. Whether this results from an increase in terminally ill patients choosing DNR status requires further study. ACP was associated with increased conversion to DNR after resuscitation and decreased hospital or ICU stays without an increase in overall mortality.

Derivation and external validation of a simple risk score for predicting severe acute kidney injury after intravenous cisplatin: cohort study.

OBJECTIVE: To develop and externally validate a prediction model for severe cisplatin associated acute kidney injury (CP-AKI). DESIGN: Multicenter cohort study. SETTING: Six geographically diverse major academic cancer centers across the US. PARTICIPANTS: Adults (≥18 years) receiving their first dose of intravenous cisplatin, 2006-22. MAIN OUTCOME MEASURES: The primary outcome was CP-AKI, defined as a twofold or greater increase in serum creatinine or kidney replacement therapy within 14 days of a first dose of intravenous cisplatin. Independent predictors of CP-AKI were identified using a multivariable logistic regression model, which was developed in a derivation cohort and tested in an external validation cohort. For the primary model, continuous variables were examined using restricted cubic splines. A simple risk model was also generated by converting the odds ratios from the primary model into risk points. Finally, a multivariable Cox model was used to examine the association between severity of CP-AKI and 90 day survival. RESULTS: A total of 24 717 adults were included, with 11 766 in the derivation cohort (median age 59 (interquartile range (IQR) 50-67)) and 12 951 in the validation cohort (median age 60 (IQR 50-67)). The incidence of CP-AKI was 5.2% (608/11 766) in the derivation cohort and 3.3% (421/12 951) in the validation cohort. Each of the following factors were independently associated with CP-AKI in the derivation cohort: age, hypertension, diabetes mellitus, serum creatinine level, hemoglobin level, white blood cell count, platelet count, serum albumin level, serum magnesium level, and cisplatin dose. A simple risk score consisting of nine covariates was shown to predict a higher risk of CP-AKI in a monotonic fashion in both the derivation cohort and the validation cohort. Compared with patients in the lowest risk category, those in the highest risk category showed a 24.00-fold (95% confidence interval (CI) 13.49-fold to 42.78-fold) higher odds of CP-AKI in the derivation cohort and a 17.87-fold (10.56-fold to 29.60-fold) higher odds in the validation cohort. The primary model had a C statistic of 0.75 and showed better discrimination for CP-AKI than previously published models, the C statistics for which ranged from 0.60 to 0.68 (DeLong P<0.001 for each comparison). Greater severity of CP-AKI was monotonically associated with shorter 90 day survival (adjusted hazard ratio 4.63 (95% CI 3.56 to 6.02) for stage 3 CP-AKI versus no CP-AKI). CONCLUSION: This study found that a simple risk score based on readily available variables from patients receiving intravenous cisplatin could predict the risk of severe CP-AKI, the occurrence of which is strongly associated with death.

Infliximab for Treatment of Immune Adverse Events and Its Impact on Tumor Response.

Background: Immune-related adverse events (irAEs) challenge the use of immune checkpoint inhibitors (ICIs). We performed a retrospective study to evaluate response to infliximab for immune-related adverse event management, and infliximab's effect on progression-free survival (PFS) and overall survival (OS) with a focus on melanoma and genitourinary cancers. Methods: We retrospectively reviewed records of all cancer patients exposed to infliximab after immune checkpoint inhibitor (ICI) treatment from 2004 to 2021 at the MD Anderson Cancer Center. Survival was assessed utilizing the Kaplan-Meier method. Univariate and multivariate logistic regression was utilized to evaluate predictors of infliximab response, OS, and PFS. Results: We identified 185 cancer patients (93 melanoma and 37 genitourinary cancers) treated with ICI and who received infliximab to treat irAEs. Within 3 months of treatment initiation, 71% of the patients responded to infliximab, 27% had no response, and 2% had unknown response. Among different irAEs, colitis was associated with increased response to infliximab at 3 months, irrespective of the type of malignancy. We evaluated best tumor response before and after infliximab in the entire cohort and again in the melanoma and genitourinary (GU); the findings were similar in the melanoma cohort and the entire cohort, where best tumor response before and after infliximab was not significantly different. In the melanoma cohort, acute kidney injury (AKI) was associated with increased risk of death, p = 0.0109, and having response to infliximab was associated with decreased risk of death, p = 0.0383. Interestingly in GU cancer patients, myositis was associated with increased risk of death, p = 0.0041, and having a response to infliximab was marginally associated with decreased risk of death, p = 0.0992. As regards PFS, in a multivariate Cox regression model, having a history of cardiovascular disease remained significantly associated with shorter PFS in the melanoma cohort. For patients with GU cancers, response to infliximab was associated with longer PFS. Conclusions: Our study is among the largest retrospective analyses of infliximab use for irAE management. Patients with colitis were the best responders to infliximab. AKI before initiation of infliximab in the melanoma subcohort and myositis in GU subcohort are associated with higher risk of death. Our results indicate no association between infliximab and cancer progression with the exception of genitourinary cancers.

Intranasal fentanyl spray versus intravenous opioids for the treatment of severe pain in patients with cancer in the emergency department setting: A randomized controlled trial.

OBJECTIVE: Intranasal fentanyl (INF) quickly and noninvasively relieves severe pain, whereas intravenous hydromorphone (IVH) reliably treats severe cancer pain but requires vascular access. The trial evaluated the efficacy of INF relative to IVH for treating cancer patients with severe pain in an emergency department (ED) setting. METHODS: We randomized 82 patients from a comprehensive cancer center ED to receive INF (n = 42) or IVH (n = 40). Eligible patients reported severe pain at randomization (≥7, scale: 0 "none" to 10 "worst pain"). We conducted non-inferiority comparisons (non-inferiority margin = 0.9) of pain change from treatment initiation (T0) to one hour later (T60). T0 pain ratings were unavailable; therefore, we estimated T0 pain by comparing 1) T60 ratings, assuming similar group T0 ratings; 2) pain change, estimating T0 pain = randomization ratings, and 3) pain change, with T0 pain = 10 (IVH group) or T0 pain = randomization rating (INF group). RESULTS: At T60, the upper 90% confidence limit (CL) of the mean log-transformed pain ratings for the INF group exceeded the mean IVH group rating by 0.16 points (>pain). Substituting randomization ratings for T0 pain, the lower 90% CL of mean pain change in the INF group extended 0.32 points below (

Renal Replacement Therapy in Patients With Stage IV Cancer Admitted to the Intensive Care Unit With Acute Kidney Injury at a Comprehensive Cancer Center Was Not Associated With Survival.

INTRODUCTION: In patients with advanced cancer, prolongation of life with treatment often incurs substantial emotional and financial expense. Among hospitalized patients with cancer since acute kidney injury (AKI) is known to be associated with much higher odds for hospital mortality, we investigated whether renal replacement therapy (RRT) use in the intensive care unit (ICU) was a significant independent predictor of worse outcomes. METHODS: We retrospectively reviewed patients admitted in 2005 to 2014 who were diagnosed with stage IV solid tumors, had AKI, and a nephrology consult. The main outcomes were survival times from the landmark time points, inpatient mortality, and longer term survival after hospital discharge. Logistic regression and Cox proportional regression were used to compare inpatient mortality and longer term survival between RRT and non-RRT groups. Propensity score-matched landmark survival analyses were performed with 2 landmark time points chosen at day 2 and at day 7 from ICU admission. RESULTS: Of the 465 patients with stage IV cancer admitted to the ICU with AKI, 176 needed RRT. In the multivariate logistic regression model after adjusting for baseline serum albumin and baseline maximum Sequential Organ Failure Assessment (SOFA), the patients who received RRT were not significantly different from non-RRT patients in inpatient mortality (odds ratio: 1.004 [95% confidence interval: 0.598-1.684], P = .9892). In total, 189 patients were evaluated for the impact of RRT on long-term survival and concluded that RRT was not significantly associated with long-term survival after discharge for patients who discharged alive. Landmark analyses at day 2 and day 7 confirmed the same findings. CONCLUSIONS: Our study found that receiving RRT in the ICU was not significantly associated with inpatient mortality, survival times from the landmark time points, and long-term survival after discharge for patients with stage IV cancer with AKI.

Cardiopulmonary resuscitation outcomes in a cancer center emergency department.

BACKGROUND: Cardiopulmonary resuscitation (CPR) after cardiac arrest is utilized indiscriminately among unselected populations. Cancer patients have particularly low rates of return of spontaneous circulation (ROSC) and survival to hospital discharge after CPR. Our study determines rates of ROSC and survival to hospital discharge among cancer patients undergoing CPR in our cancer center. We examined whether these rates have changed over the past decade. METHODS: This IRB-approved retrospective observational study was conducted in our cancer center. The ED and cancer center provide medical care for ≥ 115,000 patients annually. Cases of CPR presenting to the cancer center for years 2003-2012 were identified using Institutional CPR and Administrative Data for Resuscitation and Billing databases. Age, gender, ethnicity, ROSC and Discharge Alive using a modified Utsein template was used to compare proportions achieving ROSC and survival to hospital discharge for two time periods: 2003-2007 (Group 1) and 2008-2012 (Group 2), using traditional Pearson chi-square statistics. RESULTS: One hundred twenty-six cancer center patients received CPR from 2003-2012. Group 1 (N = 64) and Group 2 (N = 62) were similar; age (60 vs. 60 years), gender (63% vs. 58% male), and race/ethnicity (67% vs. 56% White). Proportions achieving ROSC were similar in the two time periods (36% Group 1 vs. 45% Group 2, OR = 1.47, 95% CI 0.72 - 3.00) as was survival to hospital discharge (11% Group 1 vs. 10% Group 2, OR 0.87, 95% CI 0.28 - 2.76). CONCLUSIONS: ROSC after CPR in cancer patients and survival to hospital discharge did not change over time.
