Abstract Background Bladder cancer is the most common cancer in the urinary system and the fourth most common cancer in males. This study aimed to examine differences in the survival of bladder cancer patients of different ethnicities. Method We used the SEER database to obtain data pertaining to bladder cancer patients from 2010 to 2015. Univariate and multivariate Cox proportional hazards regression analyses were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between ethnicity and death. Kaplan–Meier survival and nomogram analyses were used to compare survival differences among patients with different ethnicities. Results Among 101,364 bladder cancer patients, 90,910 were white, 5893 were black, 337 were American Indian/Alaska Native (AIAN), and 4224 were Asian or Pacific Islander (API). Our multivariate analysis identified differences between different ethnicities. Compared to the API group, the AIAN (HR = 1.31, 95% CI = 1.09–1.57, P < 0.001), black (HR = 1.56, 95% CI = 1.46–1.67, P < 0.001), and white (HR = 1.18, 95% CI = 1.12–1.25, P < 0.001) groups showed lower survival probabilities. Based on data from all Kaplan–Meier survival curves, there was no significant difference in survival between the black and AIAN groups, but the survival of these two races was worse than that of the white and API groups. We also used a nomogram to estimate patient survival and validated its predictive value. Conclusion Our results suggest that ethnic differences exist in patients with bladder cancer, that the survival of black and AIAN bladder cancer patients is worse than that of other ethnicities and that the survival of API patients is the best. The significant prognostic factors of overall survival, which include age, sex, ethnicity, summary stage, American Joint Committee on Cancer stage, surgery type, and histologic type, should be applied to bladder cancer patient prognostication.

455 Background: We started in 2008 a Multidisciplinary Bladder Cancer Clinic (MDBCC), where complex bladder cancer patients are assessed concurrently by urologic and radiation oncologists, with support from medical oncologists. Patients have the opportunity to discuss various treatment options including radical cystectomy (RC) or bladder sparing trimodal therapy (TMT; endoscopic resection, radiotherapy and chemotherapy). Although reports have shown comparable outcomes of TMT to cystectomy, no direct comparison to RC has been published and no randomized studies are available. We report our long term outcomes of multidisciplinary care, comparing TMT to surgery using propensity-matched analyses. Methods: Patients seen in our MDBCC receiving TMT for MIBC from 2008 to 2012 were identified and matched, using propensity scores, to patients operated by RC. Matching occurred on age, ECOG status, Charlson comorbidity score, cT stage, cN stage and date of treatment. Overall survival (OS) and disease-specific survival (DSS) were assessed with Cox Proportional hazards modeling and competing risk analysis, respectively. Results: Between 2008 and 2012, 248 patients were assessed in the MDBCC. Of these, 162 (65%) had MIBC. Nearly half (80) opted for radiotherapy +/- concurrent cisplatin chemotherapy and 49 underwent full bladder preservation with TMT as their primary therapy. We matched 48 TMT patients with 48 RC patients with no imbalances. Median age of the cohort was 67.5 years with 29.2% cT3/cT4. With a median follow up time of 3.62 years, there were 19 (39.6%) deaths (7 from bladder cancer) in the RC group and 15 (31.3%) deaths (6 from bladder cancer) in the TMT group. 5 year DSS was 85.2% and 84.7% with TMT and surgery, respectively (p > 0.05). There was no statistically significant difference in DSS between the two groups (HR for TMT 1.31 (0.40-4.23), p = 0.66) or in OS (HR for TMT 0.77 (0.34-1.75), p = 0.53). Conclusions: Bladder cancer patients benefit from a multidisciplinary approach.. In selected patients with MIBC, chemo-radiation yields survival outcomes similar to matched RC patients. BC patients should be offered the possibility to discuss various treatment options.

The Impact

Data supporting the use of etoposide-based therapy in hemophagocytic lymphohistiocytosis (HLH) arise largely from pediatric studies. There is a lack of comparable data among adult patients with secondary HLH. We conducted a retrospective study to assess the impact of etoposide-based therapy on outcomes in adult secondary HLH. The primary outcome was overall survival. The log-rank test was used to compare Kaplan-Meier distributions of time-to-event outcomes. Multivariable Cox proportional hazards modeling was used to estimate adjusted hazard ratios (HRs) with 95% confidence intervals (CIs). Ninety adults with secondary HLH seen between January 1, 2009, and January 6, 2020, were included. Forty-two patients (47%) received etoposide-based therapy, while 48 (53%) received treatment only for their inciting proinflammatory condition. Thirty-three patients in the etoposide group (72%) and 32 in the no-etoposide group (67%) died during follow-up. Median survival in the etoposide and no-etoposide groups was 1.04 and 1.39 months, respectively. There was no significant difference in survival between the etoposide and no-etoposide groups (log-rank <i>p</i> = 0.4146). On multivariable analysis, there was no association between treatment with etoposide and survival (HR for death with etoposide = 1.067, 95% CI: 0.633–1.799, <i>p</i> = 0.8084). Use of etoposide-based therapy was not associated with improvement in outcomes in this large cohort of adult secondary HLH patients.

Objective: The aim of this study was to investigate the clinicopathological prognostic factors of malignant ovarian germ cell tumors (MOGCT) and evaluate the survival trends of MOGCT by histotype. Methods: We extracted data on 1,963 MOGCT cases diagnosed between 2000 and 2014 from the Surveillance, Epidemiology, and End Results (SEER) database and the histological classification of MOGCT, including 5 categories: dysgerminoma, embryonal carcinoma (EC), yolk sac tumor, malignant teratoma, and mixed germ cell tumor. We examined overall and disease-specific survival of the 5 histological types. Kaplan-Meier and Cox proportional hazards regression models were used to estimate survival curves and prognostic factors. We also estimated survival curves of MOGCT according to different treatments. Results: There was a significant difference in prognosis among different histological classifications. Age, histotype, grade, SEER stage, and surgery were independent prognostic factors for survival of patients with MOGCT. For all histotypes, 1-, 3-, and 5-year survival rate estimates were >85%, except for EC, which had the worst outcomes at 1 year (55.6%), 3 years (44.4%), and 5 years (33.3%). In the distant SEER stage, both chemotherapy and surgery were associated with improved survival outcomes compared with surgery- and chemotherapy-only groups. Conclusions: Dysgerminoma patients had the most favorable outcomes, whereas EC patients had the worst survival. A young age, low grade, and surgery were all significant predictors for improved survival. In contrast, a distant SEER stage was a risk factor for poor survival. Chemotherapy combined with surgery contributed to longer survival times of patients with MOGCT in the distant SEER stage.

Abstract Background Academic medical centers invest considerably in faculty development efforts to support the career success and promotion of their faculty, and to minimize faculty attrition. This study evaluated the impact of a faculty development program called the Leadership in Academic Medicine Program (LAMP) on participants’ (1) self-ratings of efficacy, (2) promotion in academic rank, and (3) institutional retention. Method Participants from the 2013–2020 LAMP cohorts were surveyed pre and post program to assess their level of agreement with statements that spanned domains of self-awareness, self-efficacy, satisfaction with work and work environment. Pre and post responses were compared using McNemar’s tests. Changes in scores across gender were compared using Wilcoxon Rank Sum/Mann-Whitney tests. LAMP participants were matched to nonparticipant controls by gender, rank, department, and time of hire to compare promotions in academic rank and departures from the organization. Kaplan Meier curves and Cox proportional hazards models were used to examine differences. Results There were significant improvements in almost all self-ratings on program surveys (p < 0.05). Greatest improvements were seen in “understand the promotions process” (36% vs. 94%), “comfortable negotiating” (35% vs. 74%), and “time management” (55% vs. 92%). There were no statistically significant differences in improvements by gender, however women faculty rated themselves lower on all pre-program items compared to men. There was significant difference found in time-to-next promotion (p = 0.003) between LAMP participants and controls. Kaplan-Meier analysis demonstrated that LAMP faculty achieved next promotion more often and faster than controls. Cox-proportional-hazards analyses found that LAMP faculty were 61% more likely to be promoted than controls (hazard ratio [HR] 1.61, 95% confidence interval [CI] 1.16–2.23, p-value = 0.004). There was significant difference found in time-to-departure (p < 0.0001) with LAMP faculty retained more often and for longer periods. LAMP faculty were 77% less likely to leave compared to controls (HR 0.23, 95% CI 0.16–0.34, p < 0.0001). Conclusions LAMP is an effective faculty development program as measured subjectively by participant self-ratings and objectively through comparative improvements in academic promotions and institutional retention.

Introduction: Anemia has been reported to be associated with poor prognosis in patients with atrial fibrillation (AF). Concomitant thrombocytopenia (TP) may or may not affect the prescription of antithrombotic drugs and clinical outcomes in these patients. Methods: The Fushimi AF Registry is a community-based prospective survey of AF patients in Fushimi-ku, Kyoto. We defined TP as platelet counts less than 150,000/μL and anemia as hemoglobin less than 11 g/dL. Among 666 patients with anemia, we compared the clinical backgrounds and outcomes of those with TP (n=183) and those without (n=483). Results: Compared with patients without TP, patients with TP were more likely to have chronic kidney disease (75.4% vs. 61.8%, p=0.001), and less likely to have hypertension (58.5% vs. 67.0%, p=0.0393), and less likely to have dyslipidemia (27.3% vs. 38.3%, p=0.0079). Age, sex, body weight, CHADS 2 score, CHA 2 DS 2 -VASc score, HAS-BLED score, and previous major bleeding were comparable between the groups. Furthermore, prescription of anti-thrombotic drugs was comparable (Figure A). On Kaplan-Meier analysis, the incidence of all-cause death was higher in TP group (hazard ratio [HR] 1.52; 95% confidence interval [CI] 1.20-1.91, p<0.05) (Figure B-1). There was no significant difference in other adverse events between patients with and without TP (major bleeding: HR 1.11; 95% CI 0.41-3.31, p=0.8, hospitalization for heart failure: HR 1.11; 95% CI 0.74-1.61, p= 0.61 and stroke or systemic embolism: HR 0.91; 95% CI 0.43-1.78, p=0.80) (Figure B-2, 3, 4). Multivariate Cox proportional hazards regression analysis adjusting for potential confounders revealed that TP was an independent determinant of all-cause death (adjusted HR: 1.41, 95% CI; 1.11-1.78, p=0.006). Conclusions: Concomitant TP in AF patients with anemia did not affect the prescription of antithrombotic drugs, and was independently associated with all-cause death in the Fushimi AF Registry.

Abstract Abstract 2789 Poster Board II-765 Background: Cancer patients often experience comorbidities that may affect their therapeutic options, prognosis, and outcome (1). Limited studies have evaluated the characteristics and impact of comorbidities in myelodysplastic syndromes (MDS). The aim of this study was to determine the effect of comorbidities on the survival of patients with MDS. Methods: We reviewed the medical records of 500 consecutive MDS patients who presented to MD Anderson Cancer Center from January 2002 to June 2004. The Adult Comorbidity Evaluation-27 (ACE-27), a validated 27-item comorbidity index for cancer patients (2), was used to assess the severity of comorbid conditions. For each patient, we obtained demographic data and specific staging information based on the International Prognostic Scoring System (IPSS). We also collected information on stem cell transplantation (SCT), mortality and survival. Kaplan-Meier methods and log-rank tests were used to assess survival. Multivariate analysis was performed using the Cox Proportional Hazards Model. Results: Of the 500 patients included in this study, 327 (65.4%) were male, and 436 (87.9%) were white; median age at presentation was 66.6 years (17.7, 93.5); mean duration of follow-up was 23.5 months (0, 88). A total of 49% of patients had IPSS intermediate-1 or lower risk. The ACE-27 comorbidity scores were as follows: none, 106 patients (21.2%); mild, 213 (42.6%); moderate, 108 (21.6%); and severe, 73 (14.6%). Three hundred and eighty one (76.2%) patients died, and 44 (8.8%) patients underwent SCT. Overall median survival using the Kaplan-Meier method was 17.6 months. Median survival according to ACE-27 scores was: 27.9 months for no comorbidity, 18.9 months for mild comorbidity, 15.2 months for moderate comorbidity, and 9.7 months for severe comorbidity. This trend reached statistical significance (p < 0.0001). The median survival by IPSS ranged from 40.9 months for patients in the low risk group versus 8.1 months for those in the high risk category (p < 0.0001). The hazards ratio obtained from the multivariate Cox Proportional Hazards Model was 1.5 and 2.0 for moderate and severe comorbidity scores when adjusted for age and IPSS (p < 0.0001). A linear trend was also observed between the severity of comorbidity and having received SCT (p = 0.001). Of the 44 patients who had SCT, 21 (47.7%) died. The median survival of patients who did not undergo stem cell transplantation ranged from 22.7 months for patients with no comorbidity to 9.3 months for patients with severe comorbidity (p = 0.0002). Conclusion: Comorbidities had a significant impact on the survival of patients with myelodysplastic syndrome. Patients with higher ACE-27 comorbidity scores had a shorter survival than those with no comorbidity, independent of their age and the IPSS risk group. Also patients with comorbid conditions received SCT less often than those without comorbidity. A comprehensive assessment of comorbidity is therefore needed to determine the prognosis in patients with MDS. References: (1) Extermann M.

5042 Background: Most pts with bladder cancer will be treated with immunotherapy. There is concern for increased TE risk with CPIs in this already high risk population. We present the first analysis of the incidence and outcomes of venous (VTE) and arterial (ATE) thromboembolism in pts with bladder cancer treated with CPIs. Methods: Consecutive pts with bladder cancer treated with CPIs at the Cleveland Clinic from 1/2015 to 12/2019 were identified and TE events noted. Overall survival (OS) was estimated using Kaplan-Meier method and the impact of VTE on OS was evaluated using Cox proportional hazards regression. Results: Of 274 pts, 72% were men (median age 73.3 years, 89% white), 82% had pure UC, 92% had lower tract disease, and 67% had a Bajorin score ≥1 (median KPS 90, 61% visceral metastases), 59% had prior systemic therapy (median 1, range 0-4) and 36% had prior TE (14% ATE, 19% VTE, 0.4% both). At CPI initiation, 24% were on antiplatelet therapy, and 15% on therapeutic anticoagulation. CPI (median doses 5, range 8.5-59) included: 40% atezolizumab, 3% nivolumab, 57% pembrolizumab. VTE occurred in 14% (n = 37), including 8% DVT, 4% PE, 2% both. DVT locations were 56% lower limb, 26% upper limb, 15% visceral vein, 4% visceral+upper limb. 2% (n = 5) had ATE (1% CVA, 0.4% visceral, 0.4% left subclavian). 92% of VTE and all ATE occurred within 6 months of CPI initiation. The incidence of TE was 10.9% (95%CI 6.6%—15.1%) at 6 months and 19.8% (95%CI 13.3%-26.4%) at 12 months. 82% of VTE (mean 6 days) and all ATE (mean 5 days) resulted in hospitalization. Multivariate analysis showed TE (HR 2.296, 95%CI 1.451-3.632, p = 0.0004), Bajorin score 1 (HR 1.490, 95%CI 1.036-2.142, p = 0.0315), and Bajorin score 2 (HR 3.50, 95%CI 2.14-5.74, p < 0.0001) were independently associated with worse OS. Conclusions: CPIs in bladder cancer pts are associated with a high TE risk, especially within six months of initiation. TE is associated with worsened survival. Further investigation into the risk factors for CPI-associated TE is needed to identify if benefits exist from thromboprophylaxis.

Abstract Background: Studies on the correlation between serum uric acid (SUA) and all-cause mortality in peritoneal dialysis (PD) patients were mainly based on the results of baseline SUA. We aimed to analyze the change of SUA level post PD, and the correlation between follow-up SUA and prognosis in PD patients. Methods: All patients who received PD catheterization and maintaining PD in our center from March 2, 2001 to March 8, 2017 were screened. Kaplan-Meier and Cox proportional-hazards regression models were used to analyze the effect of SUA levels on the risks of death. We graded SUA levels at baseline, 6 months, 12 months, 18 months and 24 months post PD by mean of SUA plus or minus a standard deviation as cut-off values, and compared all-cause and cardiovascular mortality among patients with different SUA grades. Results: A total of 1402 patients were included, 763 males (54.42%) and 639 females (45.58%). Their average age at PD start was 49.50±14.20 years. The SUA levels were 7.97±1.79mg/dl at baseline, 7.12±1.48mg/dl at 6 months, 7.05±1.33mg/dl at 12 months, 7.01±1.30mg/dl at 18 months, and 6.93±1.26mg/dl at 24 months. During median follow-up time of 31 (18, 49) months, 173 (12.34%) all-cause deaths occurred, including 68 (4.85%) cardiovascular deaths. There were no significant differences on all-cause mortality among groups with graded SUA levels at baseline, 12 months, 18 months and 24 months during follow-up or on cardiovascular mortality among groups with graded SUA levels at baseline, 6 months, 12 months, 18 months and 24 months during follow-up. At 6 months post PD，Kaplan Meier analysis showed there was significant difference on all-cause mortality among graded SUA levels (c2=11.315, P=0.010), and the all-cause mortality was lowest in grade of 5.65mg/dl≤SUA<7.13mg/dl. Conclusion: SUA level decreased during follow up post PD. At 6 months post PD, a grade of 5.65mg/dl≤SUA<7.13mg/dl was appropriate for better patients’ survival.

5604 Background: The aim of this study is to examine changes over time in survival for African-American (AA) and white women diagnosed with cervical cancer (CeCa). Methods: Surveillance, Epidemiology, and End Results (SEER) Program data 9 for 1983-2007 were used for this analysis. Kaplan–Meier and Cox proportional hazards survival methods were used to assess differences in survival by race at 5-year intervals. Results: The study included 23,722 women; including 19,777 whites and 3,945 AA. AAs were older (51.4 vs. 49 years; p<0.001), had a higher rate of regional (38.3% vs. 31.7; p<0.001) and distant metastasis (10.5% vs. 8.5; p<0.001). AAs received less frequently cancer-directed surgery (53.1% vs. 65.7%; p<0.001), and more frequently radiotherapy (56.9% vs. 47.3%; p<0.001). AAs had a hazard ratio (HR) of 1.40 (95% CI, 1.31-1.49) of CeCa mortality compared to whites. Adjusting for SEER registry, marital status, stage, age, surgery, radiotherapy, grade and histology, AA women had a HR of 1.15 (95% CI, 1.07-1.24) of CeCa related mortality. AAs had a higher HR of all cause mortality and CeCa related mortality for all the five-year diagnosis cohorts (Table). After adjusting for the same variables, there was a significant difference in survival in the 1988-1992 group (HR 1.26; 95% CI 1.09-1.47). Conclusions: The present data indicates significant survival differences by race for women with invasive CeCa. After adjusting for SEER registry, marital status, stage, age, surgery, radiotherapy, grade and histology, only between 1988-1992 there was a difference in survival between the groups.

Abstract Background: Studies reported the hormonal receptor (HR) status was not associated with survival in metaplastic breast cancer (MBC). In addition, MBC patients cannot benefit from chemotherapy (CT). The present study aimed to evaluate the efficacy of CT on MBC patients with high risk (T1-4N2-3M0 and T4N0-1M0) by propensity-score matching (PSM). Methods: A retrospective study was performed to analyze MBC from the SEER database. Breast cancer-specific survival (BCSS) rates were analyzed using the Kaplan–Meier curve and differences assessed by log-rank tests. Cox proportional hazard models were used to assess BCSS. PSM was used to make 1:1 case-control matching.Results: We identified 3116 patients. The median follow-up time was 44 months (range, 1–321 months). 23.0% of patients were HR-positive. About 62.5% of patients received CT, which seem not to relate to HR status. Recurrence risk had a significant difference between HR-negative and HR-positive groups. In the multivariable Cox proportional hazards regression model, HR status was not associated with a better BCSS. CT had no benefit for MBC. Multivariate analyses after PSM (n=1274) confirmed that both CT and HR status were not associated with prognosis. The Kaplan–Meier curve before PSM showed that HR-negative MBC with intermediate-risk benefited from CT. For HR-positive MBC, patients with intermediate and high risk benefited from CT. However, CT could only benefit for HR-positive MBC with high risk after PSM.Conclusion: PSM analysis showed that CT could only benefit for HR-positive MBC with high risk.
