AbstractDespite a characteristic indolent course, a substantial subset of follicular lymphoma (FL) patients has an early relapse with a poor outcome. Cells in the microenvironment may be a key contributor to treatment failure. We used a discovery and validation study design to identify microenvironmental determinants of early failure and then integrated these results into the FLIPI. In total, 496 newly diagnosed FL grade 1–3 A patients who were prospectively enrolled into the MER cohort from 2002 to 2012 were evaluated. Tissue microarrays were stained for CD4, CD8, FOXP3, CD32b, CD14, CD68, CD70, SIRP-α, TIM3, PD-1, and PD-L1. Early failure was defined as failing to achieve event-free survival at 24 months (EFS24) in immunochemotherapy-treated patients and EFS12 in all others. CyTOF and CODEX analysis were performed to characterize intratumoral immunophenotypes. Lack of intrafollicular CD4 expression was the only predictor of early failure that replicated with a pooled OR 2.37 (95%CI 1.48–3.79). We next developed a bio-clinical risk model (BioFLIPI), where lack of CD4 intrafollicular expression moved patients up one FLIPI risk group, adding a new fourth high-risk group. Compared with BioFLIPI score of 1, patients with a score of 2 (OR 2.17; 95% CI 1.08–4.69), 3 (OR 3.53; 95% CI 1.78–7.54), and 4 (OR 8.92; 95% CI 4.00–21.1) had increasing risk of early failure. The favorable intrafollicular CD4 T cells were identified as activated central memory T cells, whose prognostic value was independent from genetic features. In conclusion, lack of intrafollicular CD4 expression predicts early failure in FL and combined with FLIPI improves identification of high-risk patients; however, independent validation is warranted.

Cell Death Pathways

Lung cancer is one of the leading causes of death worldwide. Cell death pathways such as autophagy, apoptosis, and necrosis can provide useful clinical and immunological insights that can assist in the design of personalized therapeutics. In this study, variations in the expression of genes involved in cell death pathways and resulting infiltration of immune cells were explored in lung adenocarcinoma (The Cancer Genome Atlas: TCGA, lung adenocarcinoma (LUAD), 510 patients). Firstly, genes involved in autophagy (n = 34 genes), apoptosis (n = 66 genes), and necrosis (n = 32 genes) were analyzed to assess the prognostic significance in lung cancer. The significant genes were used to develop the cell death index (CDI) of 21 genes which clustered patients based on high risk (high CDI) and low risk (low CDI). The survival analysis using the Kaplan–Meier curve differentiated patients based on overall survival (40.4 months vs. 76.2 months), progression-free survival (26.2 months vs. 48.6 months), and disease-free survival (62.2 months vs. 158.2 months) (Log-rank test, p < 0.01). Cox proportional hazard model significantly associated patients in high CDI group with a higher risk of mortality (Hazard Ratio: H.R 1.75, 95% CI: 1.28–2.45, p < 0.001). Differential gene expression analysis using principal component analysis (PCA) identified genes with the highest fold change forming distinct clusters. To analyze the immune parameters in two risk groups, cytokines expression (n = 265 genes) analysis revealed the highest association of IL-15RA and IL 15 (> 1.5-fold, p < 0.01) with the high-risk group. The microenvironment cell-population (MCP)-counter algorithm identified the higher infiltration of CD8+ T cells, macrophages, and lower infiltration of neutrophils with the high-risk group. Interestingly, this group also showed a higher expression of immune checkpoint molecules CD-274 (PD-L1), CTLA-4, and T cell exhaustion genes (HAVCR2, TIGIT, LAG3, PDCD1, CXCL13, and LYN) (p < 0.01). Furthermore, functional enrichment analysis identified significant perturbations in immune pathways in the higher risk group. This study highlights the presence of an immunocompromised microenvironment indicated by the higher infiltration of cytotoxic T cells along with the presence of checkpoint molecules and T cell exhaustion genes. These patients at higher risk might be more suitable to benefit from PD-L1 blockade or other checkpoint blockade immunotherapies.

Abstract Introduction: Follicular lymphoma (FL) is an indolent yet heterogeneous B-cell lymphoproliferative disorder. Most people respond to treatment well. However, a particular group of patients has a poor prognosis, and these patients are difficult to define.Patients and methods: We retrospectively analyzed FL patients treated at the University of Debrecen in the past 20 years. We investigated prognostic factors that may influence the survival of FL patients.Results: We found a standardized uptake value (SUV)max cut-off value of 9.85 at the staging PET/CT to significantly separate FL patients’ progression-free survival (PFS) (p=0.0003, HR: 0.2560, 95%CI: 0.1232-0.5318). Lymphocyte/ monocyte (Ly/Mo) ratio of 3.45 drawn at diagnosis also significantly predicted PFS (p=0.0324, HR: 1.806, 95% CI: 1.051-3.104). Combining patients’ with staging SUVmax >9.85 and Ly/Mo < 3.45 a high-risk group of FL patients can be identified (p<0.0001, HR: 0.1033, 95%CI: 0.03719-0.2868). Similarly, a significant difference was shown with a SUVmax cut-off of 3.15 at the interim PET/CT (p<0.0001, HR: 0.1535, 95%CI: 0.06329-0.3720). Combining patients with staging SUVmax >9.85 and interim SUVmax >3.15, a high-risk group of FL patients can be identified (p<0.0001, HR: 0.1037, 95%CI: 0.03811-0.2824). The PFS difference is translated into overall survival advantage (p=0.0506, HR: 0.1187, 95%CI: 0.01401-1.005).Discussion: Biological prognostic factors, such as the Ly/ Mo ratio, may improve the prognostic assessment of staging PET/CT. Nevertheless, PFS difference is translated into OS when using a combination of staging and interim SUVmax. We consider investigating additional biological prognostic factors while currently highlighting PET/CT's role in FL.

Abstract Abstract 846 We had previously reported a well tolerated regimen using single agent arsenic trioxide (ATO) (Blood 2006:107; 2627) leading to durable remissions in patients with newly diagnosed acute promyelocytic leukemia (APL). Briefly, the regimen consisted of ATO (10mg/day for adults and 0.15mg/kg/day for pediatric patients) for up to 60 days in induction; this was followed by a 28 day consolidation after a 4 week break. Four weeks after completion of consolidation, patients received ATO for 10 days/month for 6 months. A concern with the previous report was the relatively short duration of follow up. Here we report the long term follow-up data of the same cohort. As previously reported, 72 newly diagnosed cases of APL were enrolled. 62 patients (86.1%) achieved hematological remission. The remaining died prior to achieving remission. There were no primary induction failures. Twenty two (30.6%) of these patients were considered good risk group (WBC count at diagnosis <5×109/L and a platelet count >20×109/L), the rest were considered high risk. Since publication of the last report an additional 7 patients have relapsed to give a total of 13 relapses, 2 were in the good risk group and the remaining 11 in the high risk group. The relapses in the good risk group were salvaged with an autologous SCT and have durable continued second remissions. The median time to relapse was 1.5 years. Five (38.52%) of these relapses occurred beyond 2 years and included both relapses in the good risk group. At a median follow-up of 58 months the 5-year Kaplan-Meier overall survival (OS), event free survival (EFS) and disease free survival (DFS) of the entire cohort was 74.22±5.26%, 68.93±5.52% and 80.00±5.17% respectively. The 5-year OS and EFS of the good risk and high risk group was 100±00% vs. 63.30±6.9% and 90.00±6.71% vs. 59.66±6.99% respectively. Beyond induction, all deaths followed relapse of disease. There were no second malignancies reported. Besides the previously reported toxicities, which were mild and transient in most cases, there were no new toxicities that were reported on continued follow up of these cases. Since completion of therapy, in spite of counseling and advising against pregnancy, 3 males and 4 females in the reproductive age group have had 8 normal children. No abortions, still births or fetal defects were reported among patients in the reproductive age group in this cohort. Hair and nail samples from 5 cases that had completed maintenance therapy more than 24 months earlier have been collected for analysis, the results of which are awaited. At our center the cost of administering this regimen is a quarter of that of a conventional ATRA plus anthracycline based regimen. Additionally, after the initial induction therapy the rest of the treatment did not require hospital admission nor did it result in any Grade III/IV hematological toxicity. Single agent ATO based regimen as reported previously is well tolerated, results in durable remissions and does not have any significant late side effects. In the good risk group it is associated with excellent clinical outcomes while in the high risk group additional interventions are probably required to reduce the risk of late relapses. In a resource constrained environment it is probably the best option. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 4848 Objectives: the prognosis of patients with cytogenetically normal acute myeloid leukemia (CN-AML) is highly variable and can be influenced by several clinical and biological variables. Nevertheless, some biological data may be conflicting and difficult to combine with the clinical ones. Methods: in order to propose a simple scoring system, we retrospectively analysed the clinical data of 337 patients newly diagnosed with CN-AMLs, aged less than 65 years, consecutively treated in eleven hematological Italian Centres from 1990 to 2005. Two hundred nineteen patients (65%) received a fludarabine-based induction regimen. All the other patients received a conventional induction regimen, including cytarabine, one anthracycline with or without etoposide. Univariate and multivariate analysis on event free survival and overall survival (EFS and OS) were performed. Patients addressed to allogeneic stem cell transplantation were censored at the time of transplant. Factors found to be significant in univariate analysis were tested in multivariate analysis. A numerical score was derived from the regression coefficients of each independent prognostic variable. The Prognostic Index Score (PIS) for each patient was then calculated by totalling up the score of each independent variable. Patients could thus be stratified into low-risk (score = 0–1), intermediate-risk (score = 2) and high-risk group (score grater than 3). The score obtained in this group of patients (training set) was then tested on 193 patients with newly diagnosed with CN-AMLs, aged less than 65 years, enrolled in the GIMEMA LAM99p clinical trial (validation set). Results: the clinical variables that were independent prognostic factors on EFS in the training set of patients were: age > 50 yrs (regression coefficient: 0.39, HR 1.5, score = 1), secondary AML (regression coefficient: 0.90, HR 2.5, score = 2) and WBC > 20 × 10^9/L (regression coefficient: 0.83, HR 2.3, score = 2). For what concerns the OS, the same variables showed the followings statistical data: age > 50 yrs (regression coefficient: 0.48, HR 1.6, score = 1), secondary AML (regression coefficient: 0.99, HR 2.7, score = 2) and WBC > 20 × 10^ 9/L (regression coefficient: 0.87, HR 2.4, score = 2). In the training set of patients, the median EFS was 22, 12 and 8 months in the low, intermediate and high-risk group (p<0.0001). The median OS was not reached in the low-risk group and was 20 and 10 months in the intermediate and high-risk group (p<0.0001). In the validation set of patients, the median EFS was 66, 16 and 3 months in the low, intermediate and high-risk group (p<0.0001). The median OS was 66, 16 and 4 months in the low, intermediate and high-risk group (p<0.0001). Conclusions: this simple and reproducible prognostic score may be useful for clinical-decision making in newly diagnosed patients with CN-AMLs, aged less than 65 yrs. Moreover, it can be clinically useful when the molecular prognostic markers are lacking (e.g. in emerging laboratories of some developing countries) or give contradictory results. Disclosures: No relevant conflicts of interest to declare.

8052 Background: A significant proportion of patients with FL experience an early relapse and a subsequent poor outcome. While several prognostic indices have been developed, none were designed to predict early failure. Recently, we established that lack of intrafollicular CD4+ T-cell expression predicted risk of early failure, and integrating this microenvironment biomarker with the Follicular Lymphoma International Prognostic Index, termed BioFLIPI, further improved identification of FL patients at risk of early failure ( Blood 2019;134(suppl1):121). However, the microenvironment may be influenced by the genetic composition of tumor. We investigated whether the CD4 biomarker and BioFLIPI were impacted by genetic features of the tumor as assessed by a 23-gene expression prognostic score ( Lancet Oncol 2018;19:549-61). Methods: Of the 186 cases with FL grade 1-3A treated with immunochemotherapy (IC) in our prior study, 152 had digital expression quantification of 23 selected genes (23-GEP score), which used RNA from formalin-fixed, paraffin-embedded samples. Event-free survival (EFS) was defined as time from diagnosis to progression, relapse, retreatment, or death. Early failure was defined as failing to achieve EFS at 24 months. Risk of early failure was estimated using odds ratios (ORs) and 95% confidence intervals from logistic regression models. We also used Cox regression to assess associations with continuous EFS and overall survival (OS). Results: 28% of patients failed to achieve EFS24. Lack of CD4+ intrafollicular expression (38% of patients, OR = 2.33, p = 0.024) and high risk 23-GEP score (26% of patients, OR = 3.52, p = 0.001) each predicted early failure, and in a multivariable model that included FLIPI, both CD4+ (OR = 2.26, p = 0.046) and 23-GEP score (OR = 2.26, p = 0.0.057) remained predictors. Similarly, BioFLIPI modeled as a continuous score (1-4, OR per one point increase = 2.31, p < 0.001) predicted early failure, and the association remained (OR = 2.14, p < 0.001) when the high risk 23-GEP score (OR = 2.79, p = 0.013) was included in the model. When stratified on 23-GEP score, BioFLIPI was a stronger predictor of early failure in low risk (74%, OR = 2.51, p = 0.002) relative to high risk (26%, OR = 1.55, p = 0.27) patients. Similar patterns were observed for EFS and OS. Conclusions: CD4+ T-cell infiltrate and tumor gene expression appear to be independently predictive of early failure in newly diagnosed FL patients treated with IC. Future studies should integrate and validate these measures.

Purpose: Hepatocellular carcinoma (HCC) is one of the most prevalent malignant diseases worldwide and has a poor prognosis. Gene-based prognostic models have been reported to predict the overall survival of patients with HCC. Unfortunately, most of the genes used in earlier prognostic models lack prospective validation and, thus, cannot be used in clinical practice.Methods: Candidate genes were selected from GEPIA (Gene Expression Profiling Interactive Analysis), and their associations with patients’ survival were confirmed by RT-PCR using cDNA tissue microarrays established from patients with HCC after radical resection. A multivariate Cox proportion model was used to calculate the coefficient of corresponding gene. The expression of seven genes of interest (MKI67, AR, PLG, DNASE1L3, PTTG1, PPP1R1A, and TTR) with two reference genes was defined to calculate a risk score which determined groups of different risks.Results: Our risk scoring efficiently classified patients (n = 129) with HCC into a low-, intermediate-, and high-risk group. The three groups showed meaningful distinction of 3-year overall survival rate, i.e., 88.9, 74.5, and 20.6% for the low-, intermediate-, and high-risk group, respectively. The prognostic prediction model of risk scores was subsequently verified using an independent prospective cohort (n = 77) and showed high accuracy.Conclusion: Our seven-gene signature model performed excellent long-term prediction power and provided crucially guiding therapy for patients who are not a candidate for surgery.

Pancreatic ductal adenocarcinoma (PDAC) is a highly heterogeneous malignancy. Single-cell sequencing (scRNA-seq) technology enables quantitative gene expression measurements that underlie the phenotypic diversity of cells within a tumor. By integrating PDAC scRNA-seq and bulk sequencing data, we aim to extract relevant biological insights into the ductal cell features that lead to different prognoses. Firstly, differentially expressed genes (DEGs) of ductal cells between normal and tumor tissues were identified through scRNA-seq data analysis. The effect of DEGs on PDAC survival was then assessed in the bulk sequencing data. Based on these DEGs (LY6D, EPS8, DDIT4, TNFSF10, RBP4, NPY1R, MYADM, SLC12A2, SPCS3, NBPF15) affecting PDAC survival, a risk score model was developed to classify patients into high-risk and low-risk groups. The results showed that the overall survival was significantly longer in the low-risk group (p &lt; 0.05). The model also revealed reliable predictive power in different subgroups of patients. The high-risk group had a higher tumor mutational burden (TMB) (p &lt; 0.05), with significantly higher mutation frequencies in KRAS and ADAMTS12 (p &lt; 0.05). Meanwhile, the high-risk group had a higher tumor stemness score (p &lt; 0.05). However, there was no significant difference in the immune cell infiltration scores between the two groups. Lastly, drug candidates targeting risk model genes were identified, and seven compounds might act against PDAC through different mechanisms. In conclusion, we have developed a validated survival assessment model, which acted as an independent risk factor for PDAC.

Background The risk-stratification systems are repeatedly updated in accordance with the emergence of new information about the prognostic impact of anomalies and other factors. The most extensive and modern system in this time is mSMART risk stratification involving many parameters such as genetic anomalies, albumin, beta-2-microglobulin, LDH, Plasma Cell S-phase and GEP levels. It is possible to use risk-adapted treatment programs with or without ASCT. Nevertheless, the role of complex karyotype, combination of genetic abnormalities and ASCT remains unclear. Aims To estimate the genetic abnormalities in patients with newly diagnosed multiple myeloma and define the role of risk-stratification and ASCT in prognosis of disease. Methods The study included 159 patients (median age 63 years, range 28 - 83; male: female ratio - 1:1.37) with NDMM. Metaphase cytogenetics on bone marrow samples was done by standard GTG-method. FISH analyses were performed according to the manufacturer's protocol for detection primary IgH translocations, 13q (13q14/13q34) deletion, 1p32/1q21 amplification/deletion, P53/cen 17 deletion (MetaSystems DNA probes). We additional searched the t(4;14), t(6;14), t(11;14), t(14;16) and t(14;20) in patients with IgH translocation. All patient was treated by bortezomib-based programs (VD, CVD, VMP, PAD). ASCT was performed at 42% patients. Results The frequency of genetic abnormalities in NDMM patients was 49% (78/159). IgH translocation was detected in 26.4% (42/159) patients: t(11;14) - 16.3% (26/159), t(4;14) - 5.0% (8/159); TP53/del17p - 5.6% (9/159); 1p32/1q21 amp/del - 12% (19/159); hypodiploidy - 3.1% (5/159); hyperdiploidy - 1.25% (2/159); del5q - 0,6% (1/159); other - not found. Combination two aberrations was discovered in 11.9% (19/159) patients, complex abnormalities (>3 aberrations) - in 4.4% (7/159) patients. The median OS in "two aberration" and "complex abnormalities" groups were lower than in standard-risk mSMART 3.0 (normal, t(11;14), hypodiploidy, hyperdiploidy and other): 49 months, 26 months and was not reached, respectively (p=.00015). The median PFS for these groups was 12 months, 11 months and 30 months, respectively (p=.011). Differences between "two aberration" and "complex abnormalities" groups were not find (p> .05). We modified high-risk (gain 1q, p53 mutation, del 17p deletion, t(4;14), t(14;16), t(14;20), R-ISS stage III, double and triple hit myeloma) mSMART 3.0 by adding "two aberration" and "complex abnormalities" groups on based the OS and PFS results. The final analysis was based on the results of the complex examination of 87 patients: 53 patients in standard-risk group and 34 patients in high-risk group. The median OS in standard-risk mSMART 3.0 was not reached, in high-risk mSMART 3.0mod - 48 months; 5-years OS was 62% and 38%, respectively (p=0.0073). The median PFS was 43 and 29 months, respectively (p=.09). The best results of OS and PFS were reach in both groups of patient who performed ASCT. The median OS in standard-risk mSMART 3.0 with ASCT (n=37) was not reached, in high-risk mSMART 3.0mod with ASCT - 48 months (n=20); standard-risk mSMART 3.0 without ASCT - 40 months (n=16); in high-risk mSMART 3.0mod without ASCT - 22 months (n=14); 5-years OS was 81%, 60%, 33% and 28%, respectively (p=0.0015). The median PFS was not reached, 46, 22 and 19 months, respectively (p=.017). Conclusions The combination of two aberrations and complex abnormalities is unfavorable prognostic markers. The median OS and PFS was higher in standard-risk than high-risk group according mSMART 3.0mod. The ASCT can improve treatment's outcomes and life expectancy especially in patients with high-risk. It can be useful for update risk stratification in a future. Disclosures Shuvaev: Novartis: Consultancy; Pfize: Honoraria; Fusion Pharma: Consultancy; BMS: Consultancy.

Autophagy has been associated with tumor progression, prognosis, and treatment response. However, an autophagy-related model and their clinical significance have not yet been fully elucidated. In the present study, through the integrative analysis of bulk RNA sequencing and single-cell RNA sequencing, an autophagy-related risk model was identified. The model was capable of distinguishing the worse prognosis of patients with gastric cancer (GC), which was validated in TCGA and two independent Gene Expression Omnibus cohorts utilizing the survival analysis, and was also independent of other clinical covariates evaluated by multivariable Cox regression. The clinical value of this model was further assessed using a receiver operating characteristic (ROC) and nomogram analysis. Investigation of single-cell RNA sequencing uncovered that this model might act as an indicator of the dysfunctional characteristics of T cells in the high-risk group. Moreover, the high-risk group exhibited the lower expression of immune checkpoint markers (PDCD1 and CTLA4) than the low-risk group, which indicated the potential predictive power to the current immunotherapy response in patients with GC. In conclusion, this autophagy-associated risk model may be a useful tool for prognostic evaluation and will facilitate the potential application of this model as an indicator of the predictive immune checkpoint biomarkers.

8614 Background: FN is a frequent life-threatening consequence of cytotoxic chemotherapy (CT). G-CSF reduces the risk of FN, but primary (1ry) prophylaxis using G-CSF may be cost efficient only if FN incidence is ≥20%. The identification of pts at high risk for FN with simple criterias would be useful in clinical practice. Here we report a randomized phase II trial comparing G-CSF in 1ry vs 2ry prophylaxis in a high risk group of pts (based on our risk model JCO 1996;14:737, Br J Cancer 2003;88:181). Methods: Pts ≥18 years with solid tumors or NHL at high risk for FN after CT were incluable: these were pts with day 1 or day 5 lymphocytes (Ly) count ≤700/μL AND “high risk CT” (HRCT) In pts with d1 and d5 Ly ≤700/μL, the observed incidence of FN was 40% and 66% respectively G-CSF (300 to 480μg/d from d6–12) was randomized either as in 1ry prophylaxis (Arm 1), or as 2ry prophylaxis after FN (Arm 2). Primary endpoint was the rate of grade 4 FN. Hypothesis was a reduction of 40% of the risk of FN with 1ry prophylaxis. Results: Between 03/97 and 12/04, 137 pts were included in 7 centers. The median age was 53 years (range 18–80) with 54% males. Most frequent tumors were sarcomas (36%), breast carcinomas (18%), lymphomas (15%), head and neck carcinomas (10%), and lung carcinomas (6%). 23% patients had PS>1 at the first line of chemotherapy. No difference was observed in terms of duration of hospitalization or antibiotherapy. Median number of days of G-CSF administration was 14 days (0–24) vs 0 (0–17) days (p<0.0000). After the 1st course, grade 4 FN was 38% in Arm 2 (2ry prophylaxis) and 25% in Arm 1 (1ry prophylaxis), showing a 34% reduction of FN in arm 1 (p=0.14): 1ry prophylaxis was associated with a significant reduction of FN using logistic regression (p=0.04). Incidence of FN after the 2 course in pts receiving 2ry prophylaxis was 22%. Among the subgroup of pts with PS>2 and Ly ≤700/μL, (a group with a reported 20% risk for early death, Br J Cancer 2001;85:816), 2 of 8 patients (25%) died after the 1st course, vs 0/13 in the G-CSF group (p=0.05). This difference was not significant in the whole group. Conclusions: This study confirms that lymphopenic pts receiving HRCT are a high risk group of pts for FN for whom 1ry prophylaxis with G-CSF reduces the incidence of FN. [Table: see text]
