Time To Antibiotics

e18765 Background: Neutropenic fever (NF) is relatively common oncologic emergency. Present expert consensus is that anti-pseudomonas gram-negative antibiotics should be administered within 60 minutes of detecting NF. To date studies investigating this relationship in neutropenic fever patients have been either limited in size, or have failed to reliably establish a relationship between time to antibiotics (TTA) and clinical outcomes.While some studies have shown an association between TTA and outcomes in NF patients admitted from the Emergency Department, such studies do not control for the time that patients may have been febrile in the community. To address these factors, we conducted a retrospective study on the effect of TTA on mortality in oncologic patients who developed NF as inpatients. Methods: We performed retrospective chart review of all cases of NF at an NCI designated Cancer Center between 7/1/2016 and 3/27/2019. NF was defined as temperature of 101˚ F on one occasion, or 100.4˚ F sustained over 60 minutes, with an absolute neutrophil count (ANC) less than 500. TTA and survival were calculated via chart abstraction; patients lost to follow up within 180 days were censored to the 180-day mortality group. Relationship between TTA and overall survival (OS) was analyzed via multivariable Cox regression. We excluded patients that had non-cancer related NF, were transferred from another institution with NF, were admitted from the ED with NF, or transitioned to hospice. Only the first instance of NF in any admission was analyzed. Results: A total of 187 eligible cases were identified during the study period, mean age was 57.6 +/- 13.6, 100 (53.5%) cases were in males, 114 (61.0%) cases in Caucasians, 53 (28.3%) in Black People. The 3 most common disease subtypes were acute leukemia (42.8%), plasma cell dyscrasias (27.8%), and lymphoma (16.6%). TTA showed no significant correlation with OS at any timeframe studied. Low Charlson Comorbidity Index ( < 3) correlated with increased survival through ̃360 days, however the effect was non-significant at longer timeframes. Immediate antibiotic treatment ( < 40 mins) correlated with poorer patient prognosis and significantly decreased OS (HR 3.08;CI: 1.30-7.28; p 0.010). Conclusions: TTA was not associated with OS in our study. For inpatients with NF, even hours long TTA may not be long enough to result in adverse clinical outcomes. Unlike NF patients presenting to the ED, where true TTA may often be many hours or even days prior to arrival, a few hours-long TTA in the hospital may not be sufficiently long enough to cause significant patient harm. Interestingly, in our cohort, those who received antibiotics quickly had adverse outcomes. It may be that in patients who were clinically unstable, TTA was shorter given the urgency of the situation. Ultimately, this study’s findings question the applicability of the 60-minute guideline when used in the inpatient setting.

Abstract Background: Osteosarcoma is the most common primary malignant bone tumor. The current study was conducted to describe the general condition of patients with primary osteosarcoma in a single cancer center in Tianjin, China and to investigate the associated factors in osteosarcoma patients with lung metastasis. Methods: From February 2009 to October 2020, patients from Tianjin Medical University Cancer Institute and Hospital, China were retrospectively analyzed. The Kaplan–Meier method was used to evaluate the overall survival of osteosarcoma patients. Prognostic factors of patients with osteosarcoma were identified by the Cox proportional hazard regression analysis. Risk factor of lung metastasis in osteosarcoma were investigated by the logistic regression model. Results: A total of 203 patients were involved and 150 patients were successfully followed up for survival status. The 5-year survival rate of osteo-sarcoma patients was 70.0%. Surgery, bone and lung metastasis were the significant prognostic factors in multivariable Cox regression analysis. Twenty-one (10.3%) patients showed lung metastasis at the diagnosis of osteosarcoma and 67 (33%) lung metastases during the later course. T3 stage (OR=11.415, 95%CI 1.362-95.677, P=0.025) and synchronous bone metastasis (OR=6.437, 95%CI 1.69-24.51, P=0.006) were risk factors of synchronous lung metastasis occurrence. Good necrosis (≥90%, OR=0.097, 95%CI 0.028-0.332, P=0.000) and elevated Ki-67 (≥50%, OR=4.529, 95%CI 1.241-16.524, P=0.022) were proved to be significantly associated with metachronous lung metastasis occurrence. Conclusion: The overall survival, prognostic factors and risk factors for lung metastasis in this single center provided insight about osteosarcoma management.

Abstract Abstract 5018 Background: Obesity was associated with a more than 2-fold greater risk of myelodysplastic syndrome (MDS) in a recent epidemiological study (Ma et al, Am J Epidemiol. 2009 June 15; 169(12): 1492–1499). The impact of obesity on outcome of disease in patients with an established diagnosis of MDS has not been studied. We examined the prognostic value of obesity in a large cohort of lower risk MDS patients treated at the Moffitt Cancer Center (MCC). Methods: Data were collected retrospectively from the Moffitt Cancer Center (MCC) MDS database and individual charts reviewed. The primary objective was to evaluate the impact of obesity on overall survival (OS) in lower risk patients with MDS. Patients with low or intermediate-1 (int-1) risk disease by International Prognostic Scoring System (IPSS) were included. Obesity was defined as a body mass index (BMI) ≥ 30 (Standard definition) measured at time of referral to MDS program at MCC. Patients were divided into two groups according to BMI ≥ 30 or BMI < 30. All analyses were conducted using SPSS version 19.0. Chi square and independent t-test were used to compare baseline characteristics between the 2 groups for categorical and continuous variables, respectively. The Kaplan–Meier method was used to estimate median overall survival. Log rank test was used to compare Kaplan–Meier survival estimates between two groups. Cox regression was used for multivariable analysis. Results: Between January 2001 and December 2009, 479 low/int-1 IPSS risk MDS patients were included. Among those, 132 (27.6%) had BMI ≥ 30 and 325 (67.8%) had BMI <30; BMI was missing in 22 patients (4.6%). The baseline characteristics between the two groups were comparable. No difference was noted in mean age, WHO subtype, karyotype, MD Anderson risk model group, red blood cell transfusion dependency (RBC-TD), or serum ferritin (Table-1). The median OS was 59 mo (95%CI 48–70) in patients with BMI <30 compared to 44 (95%CI 38–50) in patients with BMI ≥ 30. (p=0.03). There was no difference in rate of AML transformation according to BMI, 12.9% and 15.7% respectively for BMI ≥ 30 and BMI <30. (P=0.3). In Cox regression analysis obesity predicted inferior OS (Hazard ratio (HR) 1.7 (95%CI 1.15–2.4) (P=0.007) after adjustment for age, MD Anderson risk group, serum ferritin, RBC-TD, use of hypomethylating agents and tobacco use. Conclusion: Our data suggest that obesity is an independent adverse prognostic factor for OS in patients with lower risk MDS. Obesity may be associated with other comorbidities and metabolic dearrangements that contribute to the pathogenesis of the underlying disease.

Abstract 4241 Background: Acute lymphocytic leukemia (ALL) incidence is approximately 4000 cases per year in the USA. Several standard induction regimens are used upfront for the treatment of ALL. The HyperCVAD regimen is currently a widely used upfront treatment option for adult ALL patients based on pioneer work at MD Anderson Cancer Center (MDACC). Here we present our experience with the HyperCVAD regimen treating ALL at Moffitt Cancer Center (MCC), representing the largest cohort treated with this regimen outside MDACC. Methods: Patients who were diagnosed and treated at MCC with ALL were identified through the MCC Total Cancer Care database. Individual charts were reviewed. All patients treated with the HyperCVAD regimen frontline were included in this analysis. The HyperCVAD regimen was administered as originally described at MDACC. Philadelphia positive patients were treated with addition of tyrosine kinase inhibitors (TKI) (imatinib or dasatinib). Descriptive data are reported, t-test was used to compare continuous variables, chi square test for categorical variables, Kaplan Meier curves were used for overall survival (OS). Log rank test was used to compare survival times between groups. Cox regression analysis was used for multivariable analysis. All analyses were conducted using SPSS version 19.0 Results: Between 1/1/2002 and 6/30/2011, 100 ALL patients were treated with HyperCVAD at MCC. The median age was 45 years (range 18–83), 26 were above age of 60 years and 26 were below age of 30 years. Sixty three percent were male and 37% were female. Sixty five percent were white, 6% were African America, 7% were Hispanic and 22% were described as other. B-Cell ALL accounted for 83% of patients, while the other 17% had T-Cell origin. Of the 100 patients, 23% of patients were Philadelphia chromosome positive, while 72% were negative, and in 5% karyotype was unknown. Splenomegaly was present at diagnosis in 18% of patients, while 17% presented with lymphadenopathy. Twenty-three percent of patients presented with a WBC of 50,000 or greater. CNS disease was noted in 9% of patients at diagnosis. Seventy-six percent achieved a complete response (CR), while 12% had refractory disease. Response to frontline was not documented in 12% of patients. The median overall survival was 27 months (95% CI 15.6–38.3). In univariable analysis, no difference in outcome was observed based on gender, race, Philadelphia chromosome positivity, B or T-cell origin, presence of lymphadenopathy, splenomegaly, WBC >50,000 or CNS disease at presentation. Age was a significant prognostic factor. The median OS for patients <60 years old was 34 months (95% CI 20.8–47.), and 16 months for patients >60 years old (95% CI 6.9–25.1) (p= 0.006) (figure-1) The median OS was higher in patients who achieved CR with frontline chemotherapy. OS was 34 months (95% CI 22.5–45.4) compared to 13 months in patients who did not achieve CR after frontline (95% CI 7.3–18.7) (p=< 0.005). Thirty-eight patients proceeded to allogeneic SCT. The median OS was 40 months in patients who proceeded to allogeneic SCT compared with 16 months in patients who did not (p=0.002). In Cox regression analysis, achieving CR with frontline induction, and allogeneic SCT were statistically significant independent variables for OS for adult patients with ALL. The odds ratio was 3.4 in patients achieving CR with frontline therapy, and 3.1 in patients who underwent allogeneic SCT. Conclusion: To our knowledge, this cohort represents the largest group of ALL patients treated outside MDACC with HyperCVAD based regimens, with similar overall results in the setting of tertiary centers. Achievement of CR after frontline therapy, and undergoing allogeneic SCT were statistically significant prognostic indicators. The outcome of elderly patients (age >60) was inferior. In the elderly population there were lower rates of CR and less number of patients proceeded to allogeneic SCT. The outcome in Philadelphia chromosome positive ALL has improved with the introduction of TKI’s and allogeneic SCT. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 3120 Introduction: Chemo-immunotherapy (i.e. rituximab combinations) has clearly had a significant impact on the outcome of all B-cell NHL both in terms of PFS and OS. However in the relapse/refractory setting a large proportion of pts still do very poorly especially in aggressive subtypes including DLBCL and MCL. Salvage therapy followed by HDT-ASCT in relapsed DLBCL remains the standard, though pts with early failures (<1y) and/or prior exposure to rituximab still show dismal results (CORAL data). In MCL the use of HDT-ASCT in the relapse setting is debated given the frequency of chemo-resistance leading to poor results even in second CR. The use of allogeneic transplantation was developed based on observations c/w with a clear GVL effect in NHL as illustrated by pts going into remission after DLI injections. The development of non-myeloablative approaches has allowed expansion of use of allogeneic BMT in relapsed/refractory NHL. We report here one of the largest series (179 consecutive pts) with relapsed/refractory lymphoma focusing on overall survival and outcome predictors. Methods: Utilizing Kaplan-Meier survival and Cox regression methods, we report on the outcome of 179 consecutive pts with relapsed/refractory lymphoma who underwent allogeneic stem cell transplantation at the John Theurer Cancer Center between 1995–2012. The primary study endpoint was overall survival (OS) assessed by chart and SSDI database review. Secondary study endpoints included examination of the association between overall survival and allogeneic stem cell source, donor source, development of GVHD, pre-transplant chemo-sensitivity and prior failure to HDT-ASCT (second transplant). The proportional hazards assumption was met for this analysis. Results: Survival data on 179 pts (median age 48, range 20–71) were analyzed, representing 86 deaths and 5720 total months at risk (median follow up=12.3 months). Baseline characteristics included: ECOG PS (med 1, range 0–2), diagnosis (25% DLBCL, 21% HD, 20% MCL, 13% FCL, 13% PTCL, 8% other), donor source (50% matched SIB, 31% MUD, 19% mismatched MUD), stem cell source (73% PB, 23% BM, 6% Cord) and prior autologous SCT (38%). The median OS for the entire cohort was 31.2 months. OS KM curves by selected aggressive NHL subtypes are represented in Figure 1. We performed COX regression analyses to address outlined secondary endpoints. In univariate analyses statistically significant inferior outcomes were associated with the use of mismatched unrelated donor (HR 1.4, p=.01, Figure 2), bone marrow donor stem cells vs. PBSCT (HR=1.7 p=.04), pre-transplant stable/refractory disease (HR 1.8, p=.03), absence of cGVHD (HR=4.7, p<.001) and presence of acute GVHD (HR 2.8, p=.001). No difference in OS was detected whether pts had undergone allogeneic SCT as a second transplant (med time between auto/allo=20.9 months) following relapse after auto SCT (HR 1.14, CI .75–1.73, p=.5). Conclusions: This series represents a large cohort of poor risk, relapsed/refractory lymphoma pts treated consecutively with allogeneic stem cell transplantation over a > 10-year period at our institution with the following observations: Disclosures: Mato: Celgene: Speakers Bureau; Millennium: Speakers Bureau; Seattle Genetics: Speakers Bureau; Genentech: Speakers Bureau.

559 Background: The race/ethnicity based research in colorectal cancer (CRC) care continues to remain a high priority in developing personalized medicine, and to improve overall clinical outcomes. The role of p53 abnormalities in prognostication of CRC has been evaluated earlier. The incidence of nuclear accumulation of p53 (p53nac) and its prognostic relevance in African American (AA) and non-Hispanic white patients (pts) have been investigated, and it was suggested that the clinical consequences of p53nac in CRC varies with anatomic location of the tumor and the race of the patient. However, the clinical value of p53nac in relation to age, the tumor location, and race together is not assessed. Thus, we evaluated prognostic significance of p53nac by considering the tumor location, age, race/ethnicity and p53nacin CRCs in AA and white pts. Methods: Formalin fixed paraffin embedded CRC tissues from 242 AAs and 346 whites who underwent surgery were assessed for p53nac by routine immunohistochemistry (IHC). The routine (not antigen retrieval) IHC will identify the majority of genetic alterations ( > 95% missense point mutations) and have significant association with patient survival in CRC. The association between phenotypes, p53nac status, clinicopathologic features, and overall survival were evaluated using the x2 test and Cox regression analyses. Results: Approximately equivalent proportions of distal (52%) and proximal adenocarcinomas (48%) were positive for p53nac in AA pts. In contrast, distal CRC from whites more frequently were positive for p53nac than from the proximal colon (67% vs. 34%, x2 P = 0.006). p53nac was found to be a strong predictor of poor overall survival in young ( < 65 yr) white pts with proximal tumors [hazard ratio (HR) = 2.8, 95% Confidence Intervals (CI):1.2-6.4] but not in AAs (HR = 0.7, 95% CI: 0.41-1.21). Conclusions: The findings of this study suggest that p53nac is a strong prognostic marker for young white pts with proximal colon adenocarcinomas. Our findings are clinically relevant because several small-molecule inhibitors of mutant p53 are under investigation. These studies were supported by a pilot project grant by the UAB Comprehensive Cancer center.

2028 Background: Tobacco cessation is essential to high quality oncology care. Many patients smoke when diagnosed and continue to smoke during treatment, which adversely affects treatment response and survival. Although most patients are motivated to quit, few receive effective cessation therapy. The multidisciplinary clinic (MDC), where patients, their caregivers, and key specialists coordinate care, is an ideal setting to integrate a cessation program. To assess the need for cessation services within a MDC setting, we surveyed incoming patients about their smoking status, interest in quitting, and willingness to participate in a clinic-based cessation program. Methods: The study was conducted in the Multidisciplinary Thoracic Oncology Program at Baptist Cancer Center, Memphis TN. We evaluated sociodemographic/clinical characteristics, smoking status, and tobacco dependence of consecutive new patients diagnosed with lung cancer from 2014-2019, who completed a social history questionnaire. Current smokers reported their interest in quitting and their willingness to participate in a cessation program. Chi square tests and logistic regression models were used to compare characteristics of those who would participate vs. those who would not/were unsure. Kaplan-Meier curves and multivariable Cox regression were used to evaluate the association between willingness to participate in a cessation program and overall survival, adjusted for age, sex, race, and total pack-years of smoking. Results: Of 641 patients, the average age was 69 years (range: 32-95), 47% were men, 64% white/34% black, and 17% college graduates; 90% had ever smoked, 34% currently smoked, and 24% quit smoking within the past year. Among current smokers, 60% were very interested in quitting and 37% would participate in a clinic-based cessation program. Willingness to participate was associated with greater interest in quitting (p = 0.0010) and greater overall survival (log rank p = 0.01;HR: 0.48, 95% CI: 0.24-0.95) but was not associated with any sociodemographic, clinical, or smoking-related characteristics. Conclusions: Over half (58%) of patients in a community-based MDC program were current smokers/recent quitters. Willingness to participate in a cessation program was associated with improved survival, suggesting patients with favorable prognoses are especially interested in receiving cessation support. There is considerable need for cessation services and relapse-prevention support within a coordinated, MDC lung cancer care setting.

BackgroundPancreatic ductal adenocarcinoma (PDAC) is one of the most invasive solid malignancies. Immunotherapy and targeted therapy confirmed an existing certain curative effect in treating PDAC. The aim of this study was to develop an immune-related molecular marker to enhance the ability to predict Stages III and IV PDAC patients.MethodIn this study, weighted gene co-expression network (WGCNA) analysis and a deconvolution algorithm (CIBERSORT) that evaluated the cellular constituent of immune cells were used to evaluate PDAC expression data from the GEO (Gene Expression Omnibus) datasets, and identify modules related to CD4+ T cells. LASSO Cox regression analysis and Kaplan–Meier curve were applied to select and build prognostic multi-gene signature in TCGA Stages III and IV PDAC patients (N = 126). This was followed by independent Stages III and IV validation of the gene signature in the International Cancer Genome Consortium (ICGC, N = 62) and the Fudan University Shanghai Cancer Center (FUSCC, N = 42) cohort. Inherited germline mutations and tumor immunity exploration were applied to elucidate the molecular mechanisms in PDAC. Univariate and Multivariate Cox regression analyses were applied to verify the independent prognostic factors. Finally, a prognostic nomogram was created according to the TCGA-PDAC dataset.ResultsA four-gene signature comprising NAPSB, ZNF831, CXCL9 and PYHIN1 was established to predict overall survival of PDAC. This signature also robustly predicted survival in two independent validation cohorts. The four-gene signature could divide patients into high and low-risk groups with disparity overall survival verified by a Log-rank test. Expression of four genes positively correlated with immunosuppression activity (PD-L1 and PD1). Immune-related genes nomogram and corresponding calibration curves showed significant performance for predicting 3-year survival in TCGA-PDAC dataset.ConclusionWe constructed a novel four-gene signature to predict the prognosis of Stages III and IV PDAC patients by applying WGCNA and CIBERSORT algorithm scoring to transcriptome data different from traditional methods of filtrating for differential genes in cancer and healthy tissues. The findings may provide reference to predict survival and was beneficial to individualized management for advanced PDAC patients.

ABSTRACT BACKGROUND: Hospital-based studies recently have shown increases in colorectal cancer survival, and better survival for women, young people, and patients diagnosed at an early disease stage. OBJECTIVE: To describe the overall survival and analyze the prognostic factors of patients treated for colorectal cancer at an oncology center. METHODS: The analysis included patients diagnosed with colon and rectal adenocarcinoma between 2000 and 2013 and identified in the Hospital Cancer Registry at A.C.Camargo Cancer Center. Overall 5-year survival was estimated using the Kaplan-Meier method, and prognostic factors were evaluated in a Cox regression model. Hazard ratios (HR) are reported with 95% confidence intervals (CI). RESULTS: Of 2,279 colorectal cancer cases analyzed, 58.4% were in the colon. The 5-year overall survival rate for colorectal cancer patients was 63.5% (65.6% and 60.6% for colonic and rectal malignancies, respectively). The risk of death was elevated for patients in the 50-74-year (HR=1.24, 95%CI =1.02-1.51) and ≥75-year (HR=3.02, 95%CI =2.42-3.78) age groups, for patients with rectal cancer (HR=1.37, 95%CI =1.11-1.69) and for those whose treatment was started >60 days after diagnosis (HR=1.22, 95%CI =1.04-1.43). The risk decreased for patients diagnosed in recent time periods (2005-2009 HR=0.76, 95%CI =0.63-0.91; 2010-2013 HR=0.69, 95%CI =0.57-0.83). CONCLUSION: Better survival of patients with colorectal cancer improves with early stage and started treatment within 60 days of diagnosis. Age over 70 years old was an independent factor predictive of a poor prognosis. The overall survival increased to all patients treated in the period 2000-2004 to 2010-2013.

Subjects and Methods Among patients with oropharynx cancer and confirmed HPV status, plasma CRP levels were measured with a high-sensitivity ELISA kit. Multivariable logistic regression analysis compared 4 categories of CRP (low, moderate, high, very high) between the HPV-positive and HPV-negative groups. Kaplan-Meier methods and Cox regression models were used to determine overall survival and recurrence-free survival by CRP level in both populations. Results Between 113 HPV-positive and 110 HPV-negative patients, CRP levels were significantly higher in the HPV-positive group, but these levels did not demonstrate a statistically significant dose-response trend. Higher CRP levels were also associated with reduced overall survival ( P = .016) and recurrence-free survival ( P < .001) within the HPV-negative group in univariable analysis; in multivariate analysis, the comparisons were not significantly different. Within HPV-positive oropharynx cancer, CRP levels were not significantly associated with overall survival or recurrence-free survival in univariable or multivariable analyses. Conclusion Circulating CRP was higher in HPV-positive versus HPV-negative oropharynx cancer. Among HPV-negative patients, higher CRP levels were associated with reduced survival.

Background The median age of patients diagnosed with multiple myeloma (MM) is approximately 70 years old. It is an uncommon malignancy in persons younger than 40 years, representing only 2% of all patients diagnosed with MM. It has been suggested that young patients may present with more aggressive and less common disease features, frequently delaying the initial diagnosis and thereby affecting outcomes. With this background, we explored the outcome of young MM patients presenting to our institution over the past thirteen years. Methods We performed a retrospective review of a cohort of 236 patients with MM who received treatment for active MM at the University of California, San Diego Moores Cancer Center between January 2000 and July 2013.  The demographics and disease features of patients up to 40 years of age at diagnosis were analyzed using descriptive statistics. The survival outcomes of these young patients were compared with the remainder of the cohort using the Kaplan-Meier method. Results Nineteen (6.5%) out of the 236 patients with MM were ²40 years of age at diagnosis, with a median age of 35.5 years old. The median follow-up of this group of young patients was 42 months (range 5-92). The patient and disease characteristics are outlined in Table 1. Seven young patients (37%) had MM with no heavy chain component, including light chain only secreting or non-secretory disease.  Seven patients (37%) had a non-IgG paraprotein. Nine (56%) patients presented with extramedullary plasmacytomas. Two (10%) patients had plasma cell leukemia. All patients received at least one treatment regimen that included a novel agent. Fifteen patients (79%) had received high-dose therapy, and four patients (21%) underwent allogeneic stem cell transplantation (SCT) after at least one prior autologous SCT. The 5-year and 7-year overall survival (OS) from diagnosis was 51.7% and 28%, respectively, and the median OS was 60.7 months. In contrast, the median OS of patients ≥41 years old at diagnosis was 78.6 months (p=0.15, figure 1). Conclusion In this single center study with long follow up, we demonstrate that patients diagnosed with MM ²40 years of age exhibit several high-risk features and frequently present with advanced stage disease. Despite the use of novel agents in this population, there is a statistical trend towards a worse outcome with an 18-month difference in median overall survival when compared to older patients with MM. More aggressive treatment strategies are needed to improve survival in this young patient population. Disclosures: No relevant conflicts of interest to declare.
