BackgroundVenous thromboembolic events (VTE) are commonly encountered in patients with lymphoma. Several risk assessments models (RAM) had attempted to identify higher risk patients with varying success. The International Prognostic Index (IPI) is a clinicopathological tool developed to help predict both response to treatment and prognosis of patients with diffuse large B-cell lymphoma (DLBCL).ObjectiveIn this study, we utilize the IPI index to identify group of patients with DLBCL at higher risk for VTE.Patients/MethodsPatients with pathologically-confirmed diagnosis of DLBCL and with image-confirmed VTE, treated and followed at our institution were included. Rates of VTE was calculated for each risk category.ResultsA total of 373 patients, median age 49 (range: 18-90) years were included. VTE were reported in 56 (15.0%) patients; 51 (91.1%) had active disease while 29 (51.8%) were ambulatory at time of VTE diagnosis. VTE rates were particularly high among patients with poor performance status (26.2%, P=0.028) and high LDH (19.0%, P=0.023). Applying the age-adjusted IPI separated patients into two risk categories; VTE were diagnosed in 9.7% in patients with “low and low-intermediate” scores compared to 19.8% in patients with “high and high-intermediate” scores, P=0.020.ConclusionsThe original IPI and its modified versions, routinely used at diagnosis as a prognostic and predictive tool for patients with DLBCL, can also be utilized to define high risk patients for VTE; the risk of whom might be high enough to recommend thromboprophylaxis even in the ambulatory settings. More work is needed to refine and improve currently available RAMs.

Abstract Venous thromboembolic events (VTE) are common after the diagnosis of lymphoma. Although various risk factors have been associated with VTE in cancer patients, there is no specific VTE risk prediction score for diffuse large B cell lymphoma (DLBCL) patients. The Khorana score is a prediction-model of VTE in cancer patients receiving chemotherapy that incorporates clinical and laboratory parameters. We evaluated the risk factors for VTE, the effect of VTE on the outcomes of DLBCL patients and the utility of the Khorana score in DLBCL patients. Methods: We searched the Hematologic Malignancies Database of University Hospitals Seidman Cancer Center for newly diagnosed DLBCL patients between 2002 and 2014. Data on patient characteristics including risk factors, disease characteristics, treatment, outcomes and VTE was collected. The Khorana score was calculated using clinical (disease type, body mass index) and laboratory (hemoglobin level, platelet and leukocyte count) parameters. Risk factors identified as having statistical significance on univariate Cox proportional hazards analysis (p <0.05) were selected for multivariate analysis. Cumulative incidence (with death as competing risk) was used to estimate the incidence of VTE. Overall survival (OS) and progression free survival (PFS) were calculated using the Kaplan-Meier method; comparison between groups was done using the log-rank test. Results: Four hundred DLBCL patients were included for analysis. Median age at diagnosis was 63 with 235 patients above the age of 60. Two hundred and thirty seven patients (59.3 %) had advanced stage at diagnosis and 14 patients (3.5%) had a prior history of VTE. Baseline characteristics are listed in Table 1. Sixty percent of patients had a Khorana score of 1 with no risk factors in addition to the diagnosis of lymphoma. At median follow up of 33 months, 70 patients (18%) presented a VTE, with 1-year and 3-year cumulative incidence of 10.1% (95% CI 7.1-13.6) and 14% (95 % CI 10.8-18), respectively. Fifty-seven VTE (81% of all VTEs) were diagnosed in patients with active disease (at diagnosis, relapse or during active therapy). The Khorana score separated DLBCL patients in three VTE risk groups: intermediate (1 point), high (2 points) and very high (3 or more points) with 1 year cumulative incidence of VTE of 6.4%, 11.6% and 22.2%, respectively (p = 0.009) (Figure 1). On univariate analysis, bone involvement by lymphoma, elevated corrected calcium (>12g/dL), increased white cell count (>11,000/mcl), hemoglobin (<10g/dL), monocytosis (>800/mcl) and chromosomal translocations involving MYC presented statistically significant increases in hazard of VTE (Table 2). On multivariate analysis only bone involvement (p=0.017) and anemia (p=0.035) retained statistical significance as risk factors for VTE. Three-year OS for patients presenting with VTE within 1 year of DLBCL diagnosis was 46.7 % (95% CI 30-63.3) vs. 72.3% (95% CI 67.4-77.3) in subjects without early VTE (p=0.05) (Figure 2). Presence of VTE at any time after DLBCL diagnosis was also associated with worse OS rates, with estimated 3-year OS of 52.2 % (95 % CI 39.8-64.7) for subjects experiencing VTE and 74 % (95 % CI 69-79) for those without VTE after DLBCL diagnosis (p<0.0001). Conclusion: Venous thromboembolic events are common after diagnosis of DLBCL and are associated with worsened outcomes. The Khorana score is capable of identifying patient subgroups with increased risk of VTE. Additional parameters associated with aggressive disease and advanced stages could further help in VTE risk stratification for selection of patients who may benefit from antithrombotic prophylaxis. Prospective validation of VTE risk assessments and clinical trials of VTE prevention are needed in this high=risk population.

The International Prognostic Index (IPI) identifies poor- and good-risk patients with diffuse large B cell lymphoma (DLBCL); however, the majority of patients have an intermediate IPI, with an uncertain prognosis. To determine whether cellular factors can be combined with the IPI to more accurately predict outcome, we have analyzed 177 presentation nodal DLBCLs for the expression of bcl-2 and a germinal center (GC) phenotype (defined by expression of bcl-6 and CD10). P53 gene band shifts were detected using single-stranded conformational polymorphism polymerase chain reaction analysis of exons 5-9 and were correlated with protein expression. In a Cox regression analysis, IPI (R = 0.22, P &lt; .0001) and bcl-2 (R = 0.14, P = .0001) were independent poor prognostic factors and a GC phenotype predicted a favorable outcome (R = −0.025, P = .02). Neither p53 expression nor band shifts had a significant effect on survival. Using the IPI alone, 8% of patients were identified as high risk. Expression of bcl-2 in the intermediate IPI group identified a further 28% of patients with an overall survival comparable to the high IPI group. In the intermediate IPI, bcl-2− group, the presence of a GC phenotype improved overall survival to levels approaching the IPI low group. Following this analysis only 15% of patients failed to be assigned to a favorable- or poor-risk group. Sequential addition of bcl-2 expression and GC phenotype into the IPI significantly improves risk stratification in DLBCL. For the 36% of high-risk patients with a 2-year overall survival of 19%, alternative treatment strategies should be considered in future trials.

BackgroundThe International Prognostic Index (IPI) is widely used to discriminate the prognosis of patients with diffuse large B-cell lymphoma (DLBCL). However, there is a significant need to identify novel valuable biomarkers in the context of targeted therapy, such as immune checkpoint blockade (ICB).MethodsGene expression data and clinical DLBCL information were obtained from The Cancer Genome Atlas and Gene Expression Omnibus datasets. A total of 371 immune-related genes in DLBCL patients associated with different IPI risk groups were identified by weighted gene co-expression network analysis, and eight genes were selected to construct an IPI-based immune prognostic model (IPI-IPM). Subsequently, we analyzed the somatic mutation and transcription profiles of the IPI-IPM subgroups as well as the potential clinical response to immune checkpoint blockade (ICB) in IPI-IPM subgroups.ResultsThe IPI-IPM was constructed based on the expression of CMBL, TLCD3B, SYNDIG1, ESM1, EPHA3, HUNK, PTX3, and IL12A, where high-risk patients had worse overall survival than low-risk patients, consistent with the results in the independent validation cohorts. The comprehensive results showed that high IPI-IPM risk scores were correlated with immune-related signaling pathways, high KMT2D and CD79B mutation rates, and upregulation of inhibitory immune checkpoints, including PD-L1, BTLA, and SIGLEC7, indicating a greater potential response to ICB therapy.ConclusionThe IPI-IPM has independent prognostic significance for DLBCL patients, which provides an immunological perspective to elucidate the mechanisms of tumor progression and sheds light on the development of immunotherapy for DLBCL.

AbstractThe reliable identification of diffuse large B-cell lymphoma (DLBCL)-specific targets owns huge implications for its diagnosis and treatment. Long non-coding RNAs (lncRNAs) are implicated in DLBCL pathogenesis; however, circulating DLBCL-related lncRNAs are barely investigated. We investigated plasma lncRNAs; HOTAIR, Linc-p21, GAS5 and XIST as biomarkers for DLBCL diagnosis and responsiveness to R-CHOP therapy. Eighty-four DLBCL patients and thirty-three healthy controls were included. Only plasma HOTAIR, XIST and GAS5 were differentially expressed in DLBCL patients compared to controls. Pretreatment plasma HOTAIR was higher, whereas GAS5 was lower in non-responders than responders to R-CHOP. Plasma GAS5 demonstrated superior diagnostic accuracy (AUC = 0.97) whereas a panel of HOTAIR + GAS5 superiorly discriminated responders from non-responders by ROC analysis. In multivariate analysis, HOTAIR was an independent predictor of non-response. Among patients, plasma HOTAIR, Linc-p21 and XIST were correlated. Plasma GAS5 negatively correlated with International Prognostic Index, whereas HOTAIR positively correlated with performance status, denoting their prognostic potential. We constructed the lncRNAs-related protein–protein interaction networks linked to drug response via bioinformatics analysis. In conclusion, we introduce plasma HOTAIR, GAS5 and XIST as potential non-invasive diagnostic tools for DLBCL, and pretreatment HOTAIR and GAS5 as candidates for evaluating therapy response, with HOTAIR as a predictor of R-CHOP failure. We provide novel surrogates for future predictive studies in personalized medicine.

Purpose Diffuse large B-cell lymphoma (DLBCL) is curable in 60% of patients treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). MYC translocations, with or without BCL2 translocations, have been associated with inferior survival in DLBCL. We investigated whether expression of MYC protein, with or without BCL2 protein expression, could risk-stratify patients at diagnosis. Patients and Methods We determined the correlation between presence of MYC and BCL2 proteins by immunohistochemistry (IHC) with survival in two independent cohorts of patients with DLBCL treated with R-CHOP. We further determined if MYC protein expression correlated with high MYC mRNA and/or presence of MYC translocation. Results In the training cohort (n = 167), MYC and BCL2 proteins were detected in 29% and 44% of patients, respectively. Concurrent expression (MYC positive/BCL2 positive) was present in 21% of patients. MYC protein correlated with presence of high MYC mRNA and MYC translocation (both P < .001), but the latter was less frequent (both 11%). MYC protein expression was only associated with inferior overall and progression-free survival when BCL2 protein was coexpressed (P < .001). Importantly, the poor prognostic effect of MYC positive/BCL2 positive was validated in an independent cohort of 140 patients with DLBCL and remained significant (P < .05) after adjusting for presence of high-risk features in a multivariable model that included elevated international prognostic index score, activated B-cell molecular subtype, and presence of concurrent MYC and BCL2 translocations. Conclusion Assessment of MYC and BCL2 expression by IHC represents a robust, rapid, and inexpensive approach to risk-stratify patients with DLBCL at diagnosis.

271 Background: The Windsor Regional Cancer Program (WRCP) was determined to have consistently been a top performer in time to treatment of diffuse large B cell lymphoma in this Canadian province (http://www.csqi.on.ca/by_type_of_cancer/lymphoma/lymphoma_treatment/). We endeavored to determine whether faster time to diagnosis and treatment for diffuse large B-cell lymphoma (DLBCL) influenced the IPI score (International Prognostic Score), thereby predicting an improved clinical outcome in these presenting patients. Methods: The WRCP services a catchment area of 650,000 people. A retrospective chart review was conducted for patients diagnosed with DLBCL at the Windsor Regional Cancer Program (WRCP) between 2006-2012. Information collected included the five factors for scoring by the International Prognostic Index (IPI) – age, performance status, LDH, stage, and number of extranodal sites – chemotherapy regimen, relapses, existence of second malignancies, cause of death, and dates of diagnosis, last follow-up, and death. We analyzed the relationship between prognostic factors and these clinical outcomes, and also compared the IPI scores for this cohort of patients against a similar population in another Canadian province, British Columbia. Results: It is established that compared to other cancer centres in Ontario, the WRCP is consistently reporting a shorter diagnosis to treatment metric when compared to their counterparts in Ontario, Canada. When compared to historical Canadian data, presenting IPI scores for DLBCL patients were lower on average for patients treated at the WRCP than those reported in British Columbia, Canada by Sehn et al. [Sehn, L. H., et al. (2007). The revised International Prognostic Index is a better predictor of outcome than the standard IPI for patients with diffuse large B-cell lymphoma treated with R-CHOP. Blood, 109(5), 1857-1861.]. Conclusions: A lower presenting IPI score is known to be correlated improved lymphoma related outcome. With attention to the metric of diagnosis to treatment < 30 days for diffuse large B cell lymphoma, we expect an improved lymphoma related outcome for our patients. We recommend ongoing attention to this metric, in order to improve outcomes for our patients.
