e18525 Background: Several recurrent genetic mutations have been described in acute myeloid leukemia (AML), which have both prognostic and therapeutic implications. Recurrent mutations in the Neurofibromin 1 ( NF1) gene are reported in 1-5 % of AML patients; however, there are limited data regarding its prognostic implications. Here, we report the outcomes for patients with newly diagnosed AML with a somatic NF1 mutation at our center. Methods: A retrospective chart review included patients with newly diagnosed AML at KUMC from 01/2016 through 09/2018. All patients had targeted next-generation sequencing (NGS) at diagnosis. Baseline characteristics were compared between patients with NF1 mutations and those who were wild-type using Fisher’s exact test for categorical variables, and the Wilcoxon rank-sum test for continuous variables. The primary outcome was overall survival (OS), which was measured from the time of diagnosis to the time of death from any cause. A stepwise Cox proportional-hazard model was used to adjust for potential confounders. Results: Data on 110 patients were included. Out of the 110 patients, 15 (13.6%) had a delectable NF1 mutation, while 95 (86.4%) patients were NF1 wild-type. The baseline characteristics of the two groups are displayed below. Median OS for patients with an NF1 mutation was 7.3 months, while it was 18.4 months for patients with NF1 wild-type, Log-rank test p-value 0.02. After adjusting for potential confounders, including age, ELN risk category, induction regimen, presence of other mutations such as TP53, the hazard of death remained significantly higher for patients with NF1 mutations, HR 2.4, CI (1.05-5.6), p-value 0.04. Conclusions: In this single-center retrospective study, the presence of a NF1 mutation was associated with worse overall survival in patients with newly diagnosis AML. [Table: see text]

e16547 Background: African American (AA) patients with metastatic castrate-resistant prostate cancer (mCRPC) represent a high-risk population with higher mortality. Recent data suggested that abiraterone acetate (AbA) is more effective in AA in comparison to white patients. There are limited data regarding enzalutamide (Enz) use in AAs. Here, we report the outcomes of (AbA) and (Enz) in AA patients with mCRPC at our center. Methods: A retrospective chart review included AA patients who had a diagnosis of mCRPC and were prescribed AbA and/or Enz at KUMC from 09-01-2008 through 09-01-2018. Patients were divided into two groups: those who started with AbA (abiraterone group) and those who started with Enz (enzalutamide group). Baseline characteristics were compared between the two groups using Fisher’s exact test for categorical variables and the Wilcoxon rank-sum test for continuous variables. The primary outcome was progression-free survival (PFS) on AbA and Enz. PFS was measured from the time of starting either of the two medications to the time of formal relapse, defined by relapse that required therapy change or prostate-cancer-related death. A stepwise Cox proportional-hazard model was used to adjust for potential confounders. Results: During the study period, 28 AA patients with mCRPC received AbA and/or Enz. Twenty-two patients received AbA first, while six patients received Enz first. There were no significant differences in the baseline characteristics between the two groups. Median PFS for the abiraterone group was 24.3 months, while it was 11.7 months for the enzalutamide group, Log-rank test p-value 0.04). After adjusting for potential confounders, the hazard ratio of progression remained significant, favoring the abiraterone group, HR: 0.11, p-value 0.009. Median PFS on AbA after progression on previous Enz was 5.7 months, while it was 4.5 months for Enz after progression on previous AbA, p-value 0.2. Conclusions: In this single-center retrospective study, AA patients with mCRPC who were started on AbA rather than Enz had longer PFS. More studies are needed to understand the best sequence of the two medications in this population.

Abstract Abstract 197 We and others have used gene expression profiling to classify multiple myeloma into high and low risk groups; here, we report the first combined GEP and proteomics study of a large number of baseline samples (n=85) of highly enriched tumor cells from patients with newly diagnosed myeloma. Peptide expression levels from MS data on CD138-selected plasma cells from a discovery set of 85 patients with newly diagnosed myeloma were used to identify proteins that were linked to short survival (OS < 3 years vs OS ≥ 3 years). The proteomics dataset consisted of intensity values for 11,006 peptides (representing 2,155 proteins), where intensity is the quantitative measure of peptide abundance; Peptide intensities were normalized by Z score transformation and significance analysis of microarray (SAM) was applied resulting in the identification 24 peptides as differentially expressed between the two groups (OS < 3 years vs OS ≥ 3 years), with fold change ≥1.5 and FDR <5%. The 24 peptides mapped to 19 unique proteins, and all were present at higher levels in the group with shorter overall survival than in the group with longer overall survival. An independent SAM analysis with parameters identical to the proteomics analysis (fold change ≥1.5; FDR <5%) was performed with the Affymetrix U133Plus2 microarray chip based expression data. This analysis identified 151 probe sets that were differentially expressed between the two groups; 144 probe sets were present at higher levels and seven at lower levels in the group with shorter overall survival. Comparing the SAM analyses of proteomics and GEP data, we identified nine probe sets, corresponding to seven genes, with increased levels of both protein and mRNA in the short lived group. In order to validate these findings from the discovery experiment we used GEP data from a randomized subset of the TT3 patient population as a training set for determining the optimal cut-points for each of the nine probe sets. Thus, TT3 population was randomized into two sub-populations for the training set (two-thirds of the population; n=294) and test set (one-third of the population; n=147); the Total Therapy 2 (TT2) patient population was used as an additional test set (n=441). A running log rank test was performed on the training set for each of the nine probe sets to determine its optimal gene expression cut-point. The cut-points derived from the training set were then applied to TT3 and TT2 test sets to investigate survival differences for the groups separated by the optimal cutpoint for each probe. The overall survival of the groups was visualized using the method of Kaplan and Meier, and a P-value was calculated (based on log-rank test) to determine whether there was a statistically significant difference in survival between the two groups (P ≤0.05). We performed univariate regression analysis using Cox proportional hazard model with the nine probe sets as variables on the TT3 test set. To identify which of the genes corresponding to these nine probes had an independent prognostic value, we performed a multivariate stepwise Cox regression analysis. wherein CACYBP, FABP5, and IQGAP2 retained significance after competing with the remaining probe sets in the analysis. CACYBP had the highest hazard ratio (HR 2.70, P-value 0.01). We then performed the univariate and multivariate analyses on the TT2 test set where CACYBP, CORO1A, ENO1, and STMN1 were selected by the multivariate analysis, and CACYBP had the highest hazard ratio (HR 1.93, P-value 0.004). CACYBP was the only gene selected by multivariate analyses of both test sets. Disclosures: No relevant conflicts of interest to declare.

e16661 Background: Nivolumab received accelerated approval by the FDA in 2017 for the treatment of advanced hepatocellular carcinomas (HCC). This study is aimed at evaluating the relationship between serious irAEs leading to treatment pause and survival of patients treated with nivolumab in our center. Methods: we performed a retrospective analysis of the patients treated at our center. The Kaplan Meir method was used to evaluate overall survival(OS). Log-rank test was conducted to compare groups in terms of OS. Adverse events were assessed using NCI CTCAE version 4.03 criteria. Results: Twenty patients with advanced HCC received nivolumab as palliative therapy between 2017-2019. 12/20 received nivolumab as first line treatment, 7/20 as second line. 6/20 patients stopped nivolumab due to serious irAEs including pancreatitis, kidney dysfunction and colitis leading to definitively stop of the therapy. The majority of patients received nivolumab in second line (5/6). The 1 year OS was 44% at the non-serious irAEs group and 84% in the serious irAEs group (p value = 0.0166). Median overall survival for the entire cohort was 11.4 months. The median OS was 8.11 months in patients without serious irAEs and 18.2 months in the group with toxicity. Conclusions: the occurrence of serious irAEs was associated with longer OS at our single center review. These results are in line with reports in other diseases such as lung cancer and melanoma. These retrospective data warrant further evaluation.

Abstract Background: Patients with newly diagnosed multiple myeloma is at increased risk of thrombotic events, primarily venous thrombosis. The risk is significantly increased in patients receiving certain therapeutic regimens such as the combination of thalidomide and dexamethasone. Deep vein thrombosis, especially if complicated by pulmonary embolism, can result in death. It is not clear if venous thrombotic events can result in compromised survival in this group of patients. Methods: We studied patients enrolled in the Eastern Co-operative Group trial (E1A00) that randomized patients with newly diagnosed myeloma to single agent dexamethasone or thalidomide and dexamethasone. Patients with grade 3 or greater thrombotic events (DVT, or myocardial ischemia, or stroke) were identified. Wilcoxon rank sum test (for continuous variables) or Fisher’s exact test (for categorical variables) was used to compare age, baseline M-protein, hemoglobin, WBC, platelets count, creatinine, beta2-microglobulin, or ECOG PS between patients with and without thrombotic events. Results: Among the 207 patients enrolled, 36 patients (17.4%) had grade 3 or greater thrombotic events with any treatment attribution, of whom, 27 patients had DVT, 3 patients had an MI and 6 pts had a stroke. However, in only 31 of these patients were the event considered treatment-related (possible, probable, or definite) and among these 24 had a DVT. The baseline characteristics did not differ between the patients with thrombosis and those without, irrespective of its relationship to treatment. Similarly, the baseline characteristics did not diff for those with venous or arterial thrombosis. The overall survival was similar among the patients developing a DVT compared to those without a thrombotic event, when all DVT events were considered irrespective of the treatment attribution (Figure). However, majority of the patients with an arterial event (3 patients with MI and 6 with stroke) had a short overall survival. Conclusion: Venous thrombosis remains a common complication in patients with myeloma, especially when treated with thalidomide and dexamethasone. While occurrence of thrombosis clearly contributes to morbidity and often leads to dose reductions and missed doses, it does not appear to have an adverse impact on the overall survival of these patients.

AbstractThis phase 3, multicenter, open-label study evaluated the efficacy and safety of tipifarnib compared with best supportive care (BSC), including hydroxyurea, as first-line therapy in elderly patients (≥70 years) with newly diagnosed, de novo, or secondary acute myeloid leukemia. A total of 457 patients were enrolled with 24% 80 years of age or older. Tipifarnib 600 mg orally twice a day was administered for the first 21 consecutive days, in 28-day cycles. The primary endpoint was overall survival. The median survival was 107 days for the tipifarnib arm and 109 days for the BSC arm. The hazard ratio (tipifarnib vs BSC) for overall survival was 1.02 (P value by stratified log-rank test, .843). The complete response rate for tipifarnib in this study (8%) was lower than that observed previously, but with a similar median duration of 8 months. The most frequent grade 3 or 4 adverse events were cytopenias in both arms, slightly more infections (39% vs 33%), and febrile neutropenia (16% vs 10%) seen in the tipifarnib arm. The results of this randomized study showed that tipifarnib treatment did not result in an increased survival compared with BSC, including hydroxyurea. This trial was registered at www.clinicaltrials.gov as #NCT00093990.

A new paradigm in cancer chemotherapy derives from the interaction between chemotherapeutics, including irinotecan and 5-fluorouracil (5-FU), and the immune system. The patient’s immune response can modulate chemotherapy effectiveness, and, on the other hand, chemotherapeutic agents can foster tumor cell immunogenicity. On these grounds, the analysis of the cancer patients’ immunogenetic characteristics and their effect on survival after chemotherapy represent a new frontier. This study aims to identify genetic determinants in the immuno-related pathways predictive of overall survival (OS) after FOLFIRI (irinotecan, 5-FU, leucovorin) therapy. Two independent cohorts comprising a total of 335 patients with metastatic colorectal cancer (mCRC) homogeneously treated with first-line FOLFIRI were included in the study. The prognostic effect of 192 tagging genetic polymorphisms in 34 immune-related genes was evaluated using the bead array technology. The IL15RA rs7910212-C allele was associated with worse OS in both discovery (HR: 1.57, p = 0.0327, Bootstrap p-value = 0.0280) and replication (HR:1.71, p = 0.0411) cohorts. Conversely, SMAD3 rs7179840-C allele was associated with better OS in both discovery (HR:0.65, p = 0.0202, Bootstrap p-value = 0.0203) and replication (HR:0.61, p = 0.0216) cohorts. A genetic prognostic score was generated integrating IL15RA-rs7910212 and SMAD3-rs7179840 markers with inflammation-related prognostic polymorphisms we previously identified in the same study population (i.e., PXR [NR1I2]-rs1054190, VDR-rs7299460). The calculated genetic score successfully discriminated patients with different survival probabilities (p < 0.0001 log-rank test). These findings provide new insight on the prognostic value of genetic determinants, such as IL15RA and SMAD3 markers, and could offer a new decision tool to improve the clinical management of patients with mCRC receiving FOLFIRI.

BackgroundInflammatory response in unintended tissues and organs associated with the use of immune checkpoint inhibitors also known as immune related adverse events (irAEs) is a management challenge, and renal irAEs are associated with increased patient morbidity and mortality. The most common renal toxicity is acute interstitial nephritis (AIN), characterized by infiltration of renal tissue with immune cells, and may be analogous to kidney transplant rejection. Using both clinical variables and tissue findings we evaluated a large cohort of ICI cases to determine predictors of renal response and overall survival.MethodsWe retrospectively reviewed all patients treated with ICI (August 2007 to August 2020) at MD Anderson Cancer Center. A total of 38 patients with biopsy confirmed AIN and available tissue were identified. All slides were reviewed by two board certified renal pathologists and the severity of inflammation and chronicity was graded using transplant rejection BANFF criteria. Patients were categorized as renal responders if creatinine improved or returned to baseline after treatment and non-responders if it did not. Fisher’s exact tests for categorical variables and t-test/ANOVA or the counterparts of the non-parametric approaches (Wilcoxon rank-sum or Kruskal-Wallis) for continuous variables were used to compare patient‘s characteristics between groups. The distribution of overall survival (OS) was estimated by the Kaplan-Meier method. Log-rank test was performed to test the difference in survival between groups.ResultsBased on the detailed pathological findings, patients with increased interstitial fibrosis were less likely to have renal response with treatment compared to patients with less fibrosis, (p < 0.05). Inflammation, tubulitis, number of eosinophils and neutrophils had no impact on renal response. Patients with response within 3 months of AKI treatment had a superior OS in comparison to patients who responded late (12-month OS rate: 77% vs 27%, p < 0.05). Notably, patients who received concurrent ICI and achieved renal response within 3 months had the best OS while those who did not receive concurrent ICI nor achieved renal response had worst OS (12-month OS rate: 100% (renal response and concurrent ICI) vs 72% ( renal response with no concurrent ICI), vs 27% ( no renal response and nonconcurrent ICI) (p < 0.05).ConclusionsThis is the first analysis of ICI induced nephritis where a detailed pathological and clinical evaluation was performed to predict renal response. Our findings highlight the importance of early diagnosis and treatment of ICI-AIN while continuing concurrent ICI therapy.Ethics ApprovalThis retrospective study was approved by the institutional review board at The University of Texas MD Anderson Cancer Center, and the procedures followed were in accordance with the principles of the Declaration of Helsinki.

Objective: To know the efficacy of Bronchoalveolar Lavage (BAL) in establishing diagnosis and its impact on overall health status of the patients. Methods: A single center, longitudinal study involving 40 patients aged > 18 years old with septic shock with similar baseline characteristics was conducted. Two study arms, 20 patients in intervention arm - patient with utilization of Bronchoscopy and BAL in aiding diagnosis and 20-patients in conservative- arm without Bronchoscopy were compared in terms of establishing diagnosis primarily and secondarily in terms of length of stay and 30-day mortality. We were able to identify following organisms in BAL sample: Mycobacterium tuberculosis- 4, Acinetobacter baumanii- 3, Pseudomonasaeruginosa- 2, Klebsiella oxytica- 2, E. coli- 2, Streptococcus pneumoniae- 2, Staphyloccus aureus- Results: We were able to identify various infectious agents as mentioned above 16/20 in BAL group compared to 8/20 in conventional arm; neoplasm in 4 out of 20 subjects in BAL group. In 80% of cases, BAL helped in identifying the organisms compared to only 40% in tracheal aspirate group. In addition, six cases in Intervention arm vs. nine cases in conventional arm had more than > 14 days hospital stay with the p-value 0 .492091. Interventional arm had lesser mortality 5 cases vs. 7 cases in Conventional arm with the p-value of 0.490153 which was not statistically significant. Conclusion: We conclude that the diagnostic bronchoscope and related procedures among critically ill patients are helpful in identifying the pathogens and in detecting malignancy.

Abstract Several studies have been conducted to determine the relationship between post-treatment total lymphocyte count (TLC) and overall survival (OS) in patients with malignant tumors including glioblastomas (GBMs). In this retrospective study, whether patients with newly diagnosed GBM experience significant lymphopenia after concomitant chemoradiation (CCRT) was evaluated, and whether TLC after this treatment is associated with OS in the treated population was examined. Using electronic medical records, all patients newly diagnosed with GBM between 2008 and 2016 at Seoul St. Mary’s Hospital were retrospectively examined. The eligible criteria included the following: 1) craniotomy with surgical resection or biopsy, 2) completion of CCRT, 3) accessible baseline and/or follow-up complete blood count (CBC). Median TLC significantly decreased after completion of CCRT, compared to TLC at baseline (1,742 versus 1,319 cells/mm3, P-value &lt; 0.001). Patients with TLC &lt; 1,200 cells/mm3 at 4 weeks after the completion of CCRT showed shorter survival than those with TLC ≥ 1,200 cells/mm3 with median OS of 14.5 versus 21.0 months (P-value = 0.017). Also, in multivariate analysis for OS, TLC &lt; 1,200 cells/mm3 at 4 weeks after the completion of CCRT (HR 1.97, 95% CI 1.61 – 2.25, P-value = 0.004) were significantly associated with shorter survival. The results from the present study indicate that treatment-related total lymphocyte counts after CCRT is associated with worse survival in patients with newly diagnosed GBM.

Abstract Background: Epidemiology and outcome of myelodysplastic syndromes (MDS) in the United States is not well recognized. MDS became reportable to the Surveillance, Epidemiology, and End Results program (SEER) in 2001. Only one study is published examining the SEER data between 2001–2003 on MDS incidence, epidemiology and outcome. We report first study of MDS among large population in the Veteran Affair system. Methods: There are approximately 127 VA Medical Centers diagnosing and/or treating Cancer patients. The data collected by the medical centers cancer registries is aggregated as the VA Central Cancer Registry (VACCR) and is maintained by the Chief Program Office for Oncology at VA in Washington DC. We used the VACCR to analyze VA patients with MDS diagnosed between 1995 and 2005. The data was downloaded from the database using ICD-03 histology codes for MDS. Data was entered and analyzed using bio-statistical software SPSS. Kaplan-Meier curves were used for estimates of overall survival, chi square for comparison of categorical variables and t-test for continuous variables. Results: Between 1995 and 2005, 1411 MDS cases were registered in the VACCR database. The median age was 75 years. Among those 1379 (97.7%) were males and 1196 (84.4%) were white patients, 171 (12.1%) black, and 44 (3.5%) other race. Majority of cases were reported as MDS, NOS 935 (66.3%), Refractory anemia (RA) 180 (12.8%), Refractory anemia with ring sideroblasts (RARS) 105 (7.4%), Refractory anemia with multilineage dysplasia (RCMD) 22 (1.6%), 5 q syndrome 13 (0.9%), Refractory anemia with excess blasts (RAEB) 105 (7.4%), Refractory anemia with excess blast in transformation 17 (1.2%), and therapy related MDS (t-MDS) 34 (2.4%). No IPSS data were available. The median overall survival (OS) was 1.8 year (95% CI 1.5–2.1). The 3 year and 5 year overall survival was 30% and 22% respectively. The median OS for RA patients was 3.7 year, RARS 4.9 year and for RAEB was 0.8 year. No difference was observed in OS between whites and black (median OS 1.73 versus 2.65, p value 0.28). Their was a non statistically significant trend for improvement of OS in patients diagnosed in 2004–2005 compared to 1995–2003 (time where azacitidine and lenalidomide were approved) median OS of 3.2 versus 1.8 (p value 0.64). Conclusion: This is the first report of MDS case series in the VA system. Outcome is similar to what is described in literature and SEER data (3 Year OS was 30% in our VA population study compared to 35% in recently published SEER data). No racial disparities are observed in outcome. A trend towards better overall survival is noted in the last 2 years since approval of new treatment options. Coding for WHO subtypes, IPSS and treatment options should be considered in all large MDS registries.
