Abstract Abstract 4945 Introduction Clinical trials describing LPD therapy and outcomes overwhelmingly exclude individuals ≥80 years of age. Thus, ability to deliver LPD therapy to this age group is not defined, and tolerance to therapy and response rates and survival data are not available. Methods We retrospectively identified all individuals diagnosed with any LPD at ≥80 years of age at our institution between 1997 and 2010. Data included age at diagnosis, diagnosis, therapy for LPD, comorbidities (disease count), survival from date of diagnosis of LPD, chemotherapy dose intensity (percent of 100% dose based on standard regimen dosing), hospitalization for any reason during chemotherapy, and response. Survival was analyzed by Kaplan-Meier analysis and data sets were compared using Student's t-test or Chi-square as appropriate. Results Of a total of 518 individuals diagnosed with any LPD, we identified 33(6.4%) who were diagnosed ≥80 years of age. All were male consistent with our veteran population. Data is illustrated in tables 1 and 2. Fifteen (15) had Large B-cell lymphoma, 4 CLL/SLL, 2 follicular, 2 mantle zone, 1 marginal zone, 2 lymphoplasmacytic, 3 T-cell. Two (2) could not be classified despite AFIP review. Twenty-two (22) individuals were treated with 73 cycles of chemotherapy (25 CHOP, 30 R-CHOP, 3 CVP, 11 R-CVP, 4 PO cyclophosphamide). One (1) individual with LBCL had no evidence of disease following excisional biopsy and declined further therapy, and 1 received radiotherapy. A total of 27 (82%) patients died during observation. Deaths were predominantly due to LPD. Of those not treated, 5 of 9 had low-grade LPD and were among longer-term survivors. Median survival, illustrated in the figure, was 18.8 months and was not different between treated and untreated group. This compares with 72.7 months predicted survival for an average 84-year old (WWW.SSA.GOV). Discussion LPD is common in individuals ≥80 years of age with large B-cell lymphoma being most common in our population. Despite multiple co-morbidities, the data show that reasonable dose intensity combination chemotherapy may be delivered to treat octogenarians, however hospitalization was required for 1/3 patients during chemotherapy. While survival was not different between treated and untreated groups, the individuals who were treated likely had more severe or advanced stage LPD. Prospective studies with sufficient number of individuals within each diagnostic category should be done to clarify benefits of chemotherapy in ≥80 year old patients with LPD. Disclosures: No relevant conflicts of interest to declare.

Introduction: Cardiac lymphomas are very rare with diffuse large B-cell lymphoma (DLBCL) considered to be the most common histology. These lymphomas can be either local "primary cardiac" disease, or part of dissemination by systemic lymphoma. There is limited data regarding outcomes of patients with this disease. We sought to evaluate the outcomes of cardiac DLBCL in both pre- and rituximab eras using a large retrospective database. Methods: The public Surveillance, Epidemiology and End Results (SEER) database was used to identify all patients diagnosed with DLBCL and heart as the primary disease site. Data cutoff in the database was in 2016. Patients with missing date of diagnosis or survival data were excluded. Patients were divided into two groups based on diagnosis year, with rituximab cohort included all DLBCLs diagnosed in 2006 and later (2006 was FDA approval year of rituximab in untreated DLBCL). Treatment effect (surgery, radiation, chemotherapy) was analyzed when available. survival was estimated using the Kaplan-Meier method, and compared using Log-Rank test. Cox proportional hazards models were used for adjusted survival analyses. Results: Total of 106 patients were included in the final analysis, baseline characteristics are summarized in table 1. Median age at diagnosis was 69.5 years with only about 10% of patients being 50 years or younger. Most patients were white 71 (67%), had local stage I/II disease 68 (64.2%), and belonged to the rituximab era group 71 (67%). Most patients had chemotherapy 82 (77.4%), while only 25 (23.6%) had surgery, and 16 (15.1%) had radiotherapy. Median overall survival (OS) for the entire cohort was 22 months (0-292). Median OS was 16 months (95% CI, 0.55 -31) for the pre-rituximab group, and was 26 months (95% CI, 7.5 - 45) for the rituximab group which were not statistically different (p-value =0.340). Median lymphoma-specific survival (LCS) was 30 months (95% CI, 8.0 -52) for the pre-rituximab group, and was 36 months (95% CI, 16 - 158) for the rituximab group which were not statistically different (p-value =0.295). OS and LCS were also not different between the two era groups when stratified by chemotherapy (figure 1). On univariate analysis, Chemotherapy was associated with better OS [HR = 0.472, 95% CI (0.277-0.806); p-value = 0.006] but not LCS [HR = 0.690, 95% CI (0.341-1.396); p-value = 0.302]. Using a multivariate analysis model, both OS and LCS were associated with lymphoma stage, insurance status and age but not with diagnosis era or chemotherapy (table 2). Conclusion: Cardiac DLBCLs are rare and affecting mostly the elderly. No significant improvement in outcomes were noted in the current rituximab era. Age, disease stage, and having health insurance were associated with better outcomes. The role of chemotherapy needs further evaluation in larger studies.

Introduction: Patients with diffuse large B cell lymphoma (DLBCL) arising from the testis have a relatively poor outcome. Age, stage and use of radiation and surgery are important prognostic factors in patients with primary testicular DLBCL. Additionally, the study by Gundrum et al suggested that laterality was also an important predictor of outcomes in patients with primary testicular DLBCL, with left side involvement being associated poorer prognosis. However, most patients included in the study by Gundrum et al were diagnosed in the pre-rituximab era, therefore, the role of laterality in the prognostification of patients with primary testicular DLBCL remains to be explored. In this study, the Surveillance, Epidemiology, and End Results (SEER) database was used to evaluate the prognostic roles of laterality in patients with primary testicular DLBCL. Methods: Data from the SEER 18 Registries were used to conduct this study. Cases with newly-diagnosed testicular (International Classification of Diseases for Oncology, 3rd Edition [ICDO-3] codes 9823, sites: C62.0-C63.2) in the time period between 1973 and 2015 were included. Exclusion criteria included history of cancer, unknown laterality, unknown survival data and unknown cause of death. For each case we included age at the time of diagnosis, laterality (left, right, bilateral), SEER cause-specific death classification, survival months and vital status. Overall survival (OS) was defined as time from diagnosis to death or last follow-up and cancer-specific survival (CSS) was calculated as time from diagnosis to death from DLBCL or last follow-up. Survival curves were plotted by the Kaplan-Meier method and the log-rank test was used for comparison. P value was 2-sided and P<0.05 was considered to be statistically significant. All analyses were conducted using Graphpad Prism 6. Results: A total of 1213 patients were included in this analysis. The median follow-up was 43 months (interquartile range[IQR]: 13-90 months). Of these patients, 372 patients were diagnosed from 1973-2000 (pre-rituximab era) and 841 patients were diagnosed from 2001-2015 (rituximab era). We found that patients with bilateral testis involvement had a significantly decreased CSS (median CSS: 53 vs. 142 months, P=0.0035) and OS (median OS: 32 vs. 77 months, P=0.0008) compared with those with unilateral involvement. Patients with left-side involvement had a similar CSS (median CSS: 136 vs. 153 months, P=0.2997) and OS (median OS: 76 vs. 80 months, P=0.7360) compared to those with right-side involvement. For patients with left-side involvement, patients diagnosed in the rituximab era had a significantly longer CSS(hazards ratio[HR]: 0.4140, 95% confidence interval[CI]: 0.3065 to 0.5593, P<0.0001) (Figure 1A)and OS (HR: 0.5522, 95% CI: 0.3926 to 0.6340, P<0.0001 ) (Figure 1B) than those diagnosed in the pre-rituximab era. For patients with right-side involvement, patients diagnosed in the rituximab era had a significantly longer CSS (HR: 0.7146, 95% CI: 0.5218 to 0.9029, P=0.0057) (Figure 1A)and OS (HR: 0.7116, 95% CI: 0.5407 to 0.8311, P=0.0011) (Figure 1B)than those diagnosed in the pre-rituximab era. The different HRs suggested patients with left-side primary testicular DLBCL benefited more from the introduction of rituximab. Additionally, the improvement in median OS from the pre-rituximab era to the rituximab era was 68 months for patients with left-side involvement but only 35 months for patients with right-side involvement. Conclusion: our study demonstrated that laterality was not a prognostic factor for patients with primary testicular DLBCL. And the improvement in the prognosis from pre-rituximab era to rituximab era was more remarkable in primary testicular DLBCL patients with left-side involvement than those with right-side involvement. These data suggest primary testicular DLBCL from different sides had different responses to therapy and may have different biological characteristics.

Diffuse large B-cell lymphoma (DLBCL) can be molecularly subtyped as either germinal center B-cell (GCB) or non-GCB. The role of rituximab(R) in these two groups remains unclear. We studied 204 patients with de novo DLBCL (107 treated with first-line CHOP; 97 treated with first-line R-CHOP), patients being stratified into GCB and non-GCB on the basis of BCL-6, CD10, and MUM1 protein expression. The relationships between clinical characteristics, survival data, and immunophenotype (IHC) were studied. The 5-year overall survival (OS) in the CHOP and R-CHOP groups was 50.4% and 66.6% (P=0.031), respectively. GCB patients had a better 5-year OS than non-GCB patients whether treated with CHOP or not (65.0% versus 40.9%;P=0.011). In contrast, there is no difference in the 5-year OS for the GCB and non-GCB with R-CHOP (76.5% versus 61.3%;P=0.141). In non-GCB subtype, additional rituximab improved survival better than CHOP (61.3% versus 40.9%;P=0.0303). These results indicated that addition of rituximab to standard chemotherapy eliminates the prognostic value of IHC-defined GCB and non-GCB phenotypes in DLBCL by improving the prognostic value of non-GCB subtype of DLBCL.

AbstractLineage switch involves change in the phenotypic characteristics from one type to another. It is a rare phenomenon described in mature lymphoid neoplasms which transform to histiocytic/dendritic cell tumor, more commonly described in low-grade lymphoma like follicular, chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), wherein the neoplasm loses the phenotypic characteristics of non-Hodgkin lymphoma and acquires the markers of histiocytic differentiation. Here, we present a case of diffuse large B cell lymphoma transforming to histiocytic sarcoma post 6 months of start of therapy. Histiocytic sarcoma being a very aggressive tumor, the patient had a very rapid deteriorating course and succumbed to disease.

Abstract Hepatitis C virus (HCV) has been implicated in the pathogenesis of a subset of low-grade non-Hodgkin lymphomas. Furthermore, diffuse large B-cell lymphoma (DLBCL) has been correlated to HCV infection in several series from our geographical area (north-east of Italy), but little is known about the characteristics of such high-grade tumors. We analyzed presentation features of 147 previously untreated HCV-positive patients with DLBCL who presented to the three participating centers between 1993 and 2004. All patients were provided with complete clinical information, were HIV negative, and had been tested at tumor onset for HCV antibodies by ELISA and RIBA. Median age at presentation was 64 years old (range 29–88), 47% were males, ECOG performance status was >1 in 20%, Ann Arbor stage was I in 20%, II in 27%, III in 26%, IV in 27%, and B-symptoms were present in 37% of patients. The International Prognostic Index (IPI) value at diagnosis was low in 18%, int/low in 23%, int/high in 32%, and high in 27% of patients. Surprisingly, DLBCL transformed from a low-grade histology represented only 7% of the whole population, while primary mediastinal DLBCL were extremely rare (1/147, <1%). Patients frequently presented as primary extranodal DLBCL (65/147, 44%). Most involved extranodal sites were skin, liver, stomach, and spleen, with the latter being the most represented syte (33% of patients). Remarkably, spleen was the only extranodal involved organ in 20% of patients. Treatment was delivered with cure-intent, and consisted of CHOP-like regimens +/− Rituximab for the large majority of patients, except for 16 (11%) patients with cirrhosis or severe hepatic dysfunction, who received mono-chemotherapy or radiotherapy. Only three (2%) HCV-positive patients had to discontinue chemotherapy due to liver function impairment. The addition of Rituximab to chemotherapy did not seem to affect patients’ tolerance to treatment. With a median follow-up of 48 months for survivors, 5-year overall survival (OS) was 75%, while 5-year failure-free survival (FFS) was 51%. In particular, the 65 patients with primary extranodal DLBCL shared a better 5-year OS (83% vs 71%, p=0.01) and FFS (75% vs 39%, p=0.009) than their nodal counterpart. Nodal origin of the tumor resulted the strongest independent adverse factor both in terms of OS and FFS in multivariate analysis. The peculiar clinical behavior shared by HCV-positive DLBCL may disclose relevant biological features of these tumors, and may be relevant for future studies aiming to clarify the link between HCV infection and aggressive lymphoproliferative disorders.

Abstract Introduction: The achievement of a clinical response to the first induction chemotherapy has been considered for predicting survival in patients (pts) with aggressive non-Hodgkin lymphoma (NHL). Reduced dose intensity of chemotherapy has been likely to compromise long-term outcome of the patients with aggressive NHL treated with a standard chemotherapy of cyclophosphamide (CY), doxorubicin (ADR), vincristine and prednisone (CHOP). In particular, recent studies have revealed the relevance of relative dose intensity (RDI) to clinical outcomes, with reduced RDI leading to a poor survival, as well as the impact of RDI<85% for aggressive NHL with detailed analysis of risk factors influencing reduce RDI<85% (Gary H. Lyman, J. Clin Oncol22: 4302, 2004). This study was conducted to investigate the impact of RDI<85% of CHOP on outcomes of the pts with diffuse large B-Cell lymphoma (DLCL). Methods: Data were retrospectively collected on 100 pts with DLCL who had been initially treated with more than 3 courses of CHOP (n=70) or CHOP plus rituximab (CHOP-R, n=30) at our institution between 1995 and 2006. We evaluated whether RDI might affect clinical outcomes, including complete response (CR) and event free survival (EFS). The average RDI derived from CY and ADR (referred to as RDI-CY/ADR) was determined for each patient, with classified into 2 populations according to the differences from the value of 85%, including RDI-CY/ADR<85% (n=60), and RDI-CY/ADR≥85% (n=40). Results: The median age of the study population was 54 years (range, 17 to 76), with 36 pts older than 60 years (yrs) of age. According to International Prognostic Index (IPI) score, pts were classified into 2 groups of low/ low-intermediate (n=46) and high/ high-intermediate (n=54). The overall CR rate reached 62%, and the probability of overall survival (OS) or EFS at 5 years estimated 77% or 43%, respectively with a median follow-up of 13.3 months. Multivariate analysis identified RDI-CY/ADR<85%, as well as IPI score to be associated with CR rate and EFS. Thus, RDI-CY/ADR<85% and IPI score of high/ high-intermediate were significant factors for lower CR rate (as RDI-CY/ADR≥85%, HR=0.3, 95% CI 0.1 to 0.7, p=0.009, and HR=5.5, 95% CI 2.2 to 14, p<0.001, respectively), and for reduced EFS (HR=1.9, 95% CI 1.0 to 3.7, p=0.048, and as IPI score of low/ low-intermediate HR=0.3, 95% CI 0.2 to 0.6, p<0.001, respectively). Furthermore, logrank analysis revealed that CY/ADR-RDI<85% was the significant factor for reduced EFS in non elderly pts (≤60 yrs of age), or in pts with IPI score of low/ low-intermediate (p=0.01, p=0.02, respectively). Conclusion: These data thus suggested the impact of RDI-CY/ADR<85% in influencing outcomes of the pts with DLCL, in terms of CR rate and EFS. Further investigation is currently planned to confirm this promising results with longer follow-up in larger numbers of pts with NHL.
