e20063 Background: There is a lack of data available regarding the distribution of Non-Hodgkin lymphoma (NHL) subtype, according to a recent WHO- 2016 classification and outcome of diffuse large B cell lymphoma (DLBCL) on the basis of cell of origin (COO) from developing country in Rituximab era. Methods: This is an ambispective study of newly diagnosed patients with NHL, treated in the Department of Medical Oncology, AIIMS, New Delhi. A total of 775 cases of adult ( > 18 years) lymphoma were registered over a period of 5 years (January 2014 to December 2018). Outcome of DLBCL patients who have received uniform RCHOP protocol separately analysed. The patients were classified as germinal center B-cell like (GCB) or activated B-cell (ABC) type using the Hans classification Results: NHL constituted 622 (80.26%) and Hodgkin's lymphoma 153 (19.74%) of the cases. B- cell constituted 553 (88.9%) among all NHL and rest 69 (11.1%) cases were T cell in origin.. Diffuse large B cell lymphoma (DLBCL) was the most common NHL 417(67%) followed by follicular lymphoma 60 (9.64%), mantle cell lymphoma 35 (5.62%), PTCL-NOS 25 (4.01%), ALCL 16 (2.57%),marginal zone lymphoma 14 (2.25%), T-LBL 13(2.1%) and the rest of the cases were rare NHL( < 1% cases each) for e.g. SLL, NK-T, BL, SLVL, AITL etc. Among the 417 cases of DLBCL, 262 (62.8%) cases received rituximab along with CHOP regimen. The median age of RCHOP treated patients was 47.6 years with male female ratio of 2.3:1. B symptoms were seen in 39% patients and bulky disease in 33%. ECOG performance status of 0-2 was present in 67% and 51% presented with advanced disease. GCB was seen in 42% and 44% were ABC. Low risk IPI was seen in 48 % and 40% were intermediate risk IPI. The overall response rate (ORR) was 82 % with a complete response rate (CR) of 75.6 %. Presence of bulky disease and non-radiotherapy treatment protocols were associated with inferior CR rate. After a median follow up of 30 months, the 3-year event free (EFS) survival and overall survival (OS) were 78 % and 88 % respectively. Low albumin ( < 4 gm/dl) and age > 60 years were associated with inferior EFS whereas high IPI risk score was associated with inferior OS. Pre-phase was used in 20% of cases. Grade III/ IV anaemia, neutropenia and thrombocytopenia were seen in 5%, 13% and 2% of patients respectively. Febrile neutropenia was seen in 7 % of patients and there were 3 treatment related death. Rituximab infusion related toxicity was seen in 7 patients. Conclusions: DLBCL is the most common NHL ( GC-42%, ABC-44%). The distribution according to COO dose not impact on CR rate and EFS and OS . RCHOP is well tolerated in our patients and results are comparable with the western data.

Abstract Background: The main mechanism of action of rituximab is through antibody-dependent cellular cytotoxicity via Fc receptors for immunoglobulin G. Recently a polymorphism of Fc was reported, which consists in the substitution of phenylalanine for valine in position 158. Patients with homozygous 158 valine/valine (V/V) alleles of Fc showed a higher response rate to rituximab treatment in contrast to patients with phenylalanine/valine (F/V) or homozygous phenilalanine (F/F). It would have clinical value to know which patients could have a greater benefit from the treatment with rituximab. Aims: 1-to determine the Fc genotype in patients with Non-Hodgkin lymphoma (NHL) in our population. 2- to analyze the response rate to rituximab of these patients according to the Fc polymorphism. Methods: DNA was isolated from peripheral blood. Genotyping of FCyIIIa polymorphism was performed using a polymerase chain reaction and were confirmed by direct sequencing of the region of interest. To analyse the results the patients were divided into two groups: with valine expression: V/V or V/F, and without valine expression F/F. The response was evaluated after 3 months of treatment and at the end of it. Chi-square and Fisher’s exact tests were used for statistical analysis. Results: 34 patients with NHL: 19 follicular lymphoma, 12 diffuse large B-cell lymphoma, 3 mantle lymphoma. The FcyIIIa polymorphism expression was 11.8% V/V, 52.9% V/F and 35.3% F/F. The complete response (CR) after 3 months of treatment was 50% and 41.7% for V/V-V/F and F/F respectively (not statistically significant (ns)). After end of treatment CR was 86.7% in V/V-V/F and 72.7% in F/F(ns). In patients with follicular lymphoma the CR after end of treatment was 87.5% in V/V-V/F and 79% in F/F (ns). In patients with diffuse large B-cell lymphoma the CR was reached in all patients regardless of polymorphism. Conclusions: FcyIIIa gene polymorphism did not help in predicting response after treatment with rituximab in our group of patients with NHL. A large number of patients would be necessary to draw conclusions, especially in the group with follicular lymphoma.

e20079 Background: Primary extranodal diffuse large B cell lymphoma (DLBCL) forms upto 40-50% of all cases of DLBCL . Clinicopathological features and outcome of extranodal DLBCL patients especially in the rituximab era are scarce from developing countries. Methods: We carried out an ambispective analysis of newly diagnosed DLBCL patients (n = 417) over a period of 5 years (2014-2018).Of this total cohort 224 (53.7%) were found to have primary or predominant extranodal involvement. Prognostic factors were identified using Cox-regression analyses. Results: Median age was 50 years (18-86) with male female ratio of 2:1. B symptoms were seen in 48% patients and bulky disease in 39%. ECOG performance status of 0 or 1 was present in 50% and 63% presented with advanced disease. Bone was the most common site of extranodal involvement (32%) in our study followed by gastrointestinal tract ( 30%).Cell of origin (based on Hans algorithm) was available in 80% patients with Germinal center subtype (GCB) forming 44% and non-GCB forming 36% of all patients. Bone marrow involvement was present in 13 % patients. Low risk International Prognostic Index (IPI) was seen in 32 % and 41% were having intermediate risk IPI, the remaining being high risk. CHOP based treatment was used in 80 % of cases and rituximab was used in 76% of all cases. The overall response rate was 76% with a complete response rate (CR) of 65.5%. Presence of B-symptoms, central nervous system (CNS) involvement, non R-CHOP regimen and non-radiotherapy treatment protocols were associated with inferior CR rate. After a median follow up of 26 months, the 3-year event free survival and overall survival were 65 % and 82.7 % respectively. Involvement of specific extranodal sites (kidney, adrenals and CNS), high IPI score and use of non R-CHOP regimens were associated with poor EFS and OS on multivariate analysis Conclusions: This is one of the largest studies from India on extranodal DLBCL in the rituximab era. Involvement of specific extranodal sites, high IPI score and use of non R-CHOP regimens were associated with inferior survival.

Abstract Non-Hodgkin lymphoma (NHL) consists of a heterogeneous group of tumors. Population-based data on the familial risk for specific histopathologic subtypes have not been established. Such data are useful for clinical counseling and for searching tumor subtypes sharing common genetic pathways. We used the Swedish Family-Cancer Database to calculate standardized incidence ratios (SIRs) for histopathology-specific subtypes of NHL in 4455 offspring with NHL whose parents or siblings were affected with different types of lymphoproliferative malignancies. A familial history of NHL significantly increased the risk for NHL (SIRparent = 1.8; SIRsibling = 1.9) and for diffuse large B-cell lymphoma (SIRparent = 2.3), follicular lymphoma (SIRsibling = 2.3), and B-cell lymphoma not otherwise specified (NOS) (SIRsibling = 3.4). For a parental history of histopathology-specific concordant cancer, the risks were significantly increased for diffuse large B-cell lymphoma (SIR = 11.8), follicular NHL (SIR = 6.1), plasma cell myeloma (SIR = 2.5), and chronic lymphocytic leukemia (SIR = 5.9). Familial clusters for NHL seemed stronger in females and in siblings. Our study provides the first quantification of the familial risks for NHL by histopathology. The present findings give evidence for a strong familial association of NHL, with little differences in the magnitude of risks for various histopathologic subtypes. The patterns of risks in parents and siblings support the hypothesis of an autosomal-dominant component for diffuse large B-cell NHL and a recessive one for follicular NHL. (Blood. 2005;106:668-672)

Background: Follicular lymphoma grade 3 has a natural history that is more akin to that of diffuse large B-cell lymphoma. The addition of rituximab to standard CHOP has resulted in improved response and survival in diffuse large B-cell lymphoma. Information about outcomes in follicular lymphoma grade 3 is lacking. Methods: A single institution retrospective review of patients with follicular grade 3 lymphoma evaluated at the UTMDACC from 1999 to 2004. Patients were located from the UTMDACC lymphoma database. All patients were initially treated with R-CHOP. Results: Forty-five patients were identified: 51% male, 47% ≥60 years, and 87% follicular grade 3b. The LDH was elevated in 24%, ECOG performance status was >1 in 2%, and >1 site of extranodal involvement was present in 10%. Stage distribution was 11% stage I, 11% stage II, 42% stage III, and 36% stage IV, bulky disease (>7cm) was present in 11%, and B symptoms occurred in 13%. Beta-2 microglobulin was elevated in 57% with values >3 μg/dL in over 50%. IPI distribution was: 46% IPI Low, 38% LI, 11% IH, and 4% IPI High. Overall response rate was 100% with 96% complete responses. Relapse rate by IPI category was 24% for Low IPI, 18% for IPI LI, and 40% for IPI IH, and 100% for the two patients with High IPI. With median follow-up of 33 months, three year failure-free survival (FFS) is 73% (95% CI: 59 to 87%). One patient died (2%) with an overall survival (OS) at three years of 97% (95% CI: 93 to 100%). Conclusion: The addition of rituximab to CHOP provided a high response rate and excellent early survival in this group of mostly good prognosis patients. Relapses were still seen; longer follow-up is needed.

Abstract Background In the rituximab era, there are several studies that have reported the risk factors for central nervous system (CNS) involvement in non-Hodgkin lymphoma, but the same factors emerge, such as high international prognostic index (IPI) score, >1 extranodal site, elevated lactate dehydrogenase (LDH) level, poor performance status (PS), advanced stage, bone marrow involvement. Macrophages are an important component of the tumor microenvironment and the immune response to malignancy. Recently, elevated peripheral blood monocyte counts have been shown to be an independent marker associated with poor prognosis in patients with both non-Hodgkin and Hodgkin lymphoma. Patients and methods We reviewed data from a total of 1238 lymphoma patients(1185 non-Hodgkin lymphoma, 53 Hodgkin lymphoma) at our institution between February 2005 and May 2013. Of these, 42 patients (3.4%) developed CNS complications during the clinical course. Thirty patients out of these 42 (71.4%) were diagnosed with diffuse large B-cell lymphoma (DLBCL). Therefore, we focused on DLBCL. In this study, we retrospectively analyzed data from a total of 557 DLBCL patients, 30 patients (5.4%) who developed CNS involvement and 527 patients with DLBCL but without CNS involvement. This study was approved by the Institutional Review Board of the Cancer Institute Hospital of the Japanese Foundation for Cancer Research. The clinical features of all 557 DLBCL patients, including 30 patients with CNS involvement, are summarized in Table 1. CNS involvement was defined by the presence of at least one histologically confirmed CNS involvement; neuroimaging findings compatible with CNS involvement with lymphoma, in conjunction with consistent clinical presentation; and the absence of other clinically feasible diagnosis or positive cerebrospinal fluid (CSF) (lymphoma cells detected by cytology). The absolute monocyte counts (AMC) and monocyte ratio were derived from pre-treatment complete blood counts. Pathological studies Immunohistochemical analysis was carried out using mAbs against CD68 at our institution. Results The incidence of CNS involvement was 5.4%, 1.3% having CNS involvement at diagnosis with DLBCL. Intriguingly, absolute monocyte counts (AMC) ≥0.6 (×109/L) at diagnosis were significantly frequent in 30 DLBCL patients (p=0.0420) with CNS involvement, compared with in 527 DLBCL patients without CNS involvement. Furthermore, the monocyte ratio ≥8% in peripheral blood at diagnosis was significantly frequent in 30 DLBCL patients (p=0.0325) with CNS involvement, compared with in 527 DLBCL patients without CNS involvement. DLBCL patients with CNS involvement showed age ≤60 years, stage III-IV, IPI score ≥3, and PS ≥2, elevated soluble IL-2 receptor levels was significantly frequent, compared with in DLBCL patients without CNS involvement. Neither gender, elevated LDH level, white blood cell counts (WBC) differed significantly in the two groups. With regard to pathological immunohistochemistry, the numbers of CD68 positive cells in or around lymphoma samples did not differ in the 14 DLBCL patients with CNS involvement that we were able to analyze, compared with DLBCL patients without CNS involvement. CNS involvement free survival rate in DLBCL patients was significantly lower in AMC ≥0.6 (×109/L) and/or the monocyte ratio ≥8% (Log-rank test, P=0.0102) in peripheral blood at diagnosis, compared with in AMC less than 0.6 (×109/L) and the monocyte ratio less than 8%. Conclusions These results suggest that in DLBCL patients, AMC and monocyte ratios in peripheral blood at diagnosis are closely correlated with the risk of eventual CNS involvement. AMC and monocyte ratios in peripheral blood at diagnosis in DLBCL patients could be a useful prognostic marker for the risk of CNS involvement during the clinical course.

Abstract Objective Diffuse Large B Cell Lymphoma (DLBCL) is the most common type of Non-Hodgkin Lymphoma (NHL). The aim of this study was to assess the clinico pathological characteristics of DLBCL specifically, among the affected individuals residing in Northern areas of Pakistan who had not been previously included in major lymphoma studies due to their remote location. Results Mean age of the patients was 49.7 years. Male: female ratio was 1.5:1. Primary site was lymph node in 99 (71.74%) patients, out of which, 36 (26.09%) patients had B symptoms and 19 (13.77%) patients had stage IV disease. 39 (28.26%) patients had primary extra nodal involvement, 4 (2.90%) patients had B symptoms and 3 (2.17%) had stage IV disease. Extra nodal sites involved in primary extra nodal DLBCL were gastrointestinal tract (GIT) 19 (48.72%), tonsils 6 (15.38%), spine 4 (10.26%), soft tissue swelling 3 (7.69%), parotid gland 2 (5.13%), thyroid 2 (5.13%) central nervous system (CNS) 1 (2.56), breast 1 (2.56%) and bone marrow 1 (2.56%). Our study revealed increased percentage of patients with nodal DLBCL in stage IV and with B symptoms. Few patients with primary extra nodal DLBCL had B symptoms and stage IV disease at presentation. GIT was the most common site of involvement in primary extra nodal DLBCL.

Abstract We evaluated the prevalence and clinical significance of CNS involvement in childhood and adolescence Non-Hodgkin Lymphoma (NHL). Between 10/86 and 12/02, 2,086 eligible patients (pts) were registered in the subsequent multicenter trials NHL-BFM86, −90, −95. Median follow up was 6.5 years (0.3–17.7 years). Initial staging included examination of cerebrospinal fluid (CSF) and cranial CT or MRI. CNS involvement was diagnosed in case of CSF blasts, and/or intracerebral mass (ICM), and/or cranial nerve palsy (CNP), not caused by an extradural mass. Epidural NHL without any of the above criteria was not considered as CNS disease. CNS positive (pos) pts with lymphoblastic lymphoma (LBL) received an 8-drug induction, consolidation, re-intensification, and maintenance up to 2 years. CNS therapy included dexamethason, methotrexate (MTX) 5 g/m2 i.v., 13 dosis of intrathecal (i.th.) MTX, and cranial radiotherapy (CRT). CNS pos pts with non-LBL received six 5-day courses based upon vincristine, vindesine, dexamethason, oxazophorins, cytarabine, etoposide, doxorubicin, MTX 5 g/m2 i.v., and intraventricularely or i.th. applied chemotherapy. CRT was omitted since study BFM90, except for pts with anaplastic large cell lymphoma (ALCL). 111 of the 2,086 analyzed NHL pts were initially diagnosed as CNS pos. 1,933 pts were CNS negative (neg) and in 42 pts the CNS status was questionable or not evaluable due to incomplete diagnostics. Prevalence and outcome of CNS pos pts according to NHL subtypes were as follows. In the total group, the probability of event free survival at 5 years (pEFS) was 63 ± 5% for CNS pos pts compared to 81 ± 1% for CNS neg pts with stage III/IV NHL (n=1,323) (p&lt; 0.0001). In LBL pts pEFS was 81 ± 10% for CNS pos pts and 84 ± 2% for CNS neg pts with stage III/IV (n=359) (p=0.54), while in Burkitt/B-ALL pEFS was 60 ± 5 % for CNS pos pts versus 85 ± 1% for CNS neg pts with stage III/IV (n=599) (p&lt;0.0001). For CNS pos Burkitt/B-ALL pts pEFS was 57 ± 7% for 57 pts with and was 67 ± 10% for 24 pts without bone marrow involvement (p=0.31).

Abstract We report the first case of composite Nodular Sclerosis Hodgkin and Diffuse Large B-Cell Non-hodgkin’s lymphoma of the mediastinum. We present a case of an inmunocompetent patient operated on for a mediastinal tumor similar to a Thymoma, which the histological examination morphological, and immunophenotyping were performed and confirmed the existence of 2 independent, unrelated tumors. The pathology blocks submitted show a composite lymphoma, with components of both classical Hodgkin lymphoma (Hodgkin’s disease), nodular sclerosis type, grade 2 of 2 in all three blocks. One block also shows non-Hodgkin lymphoma, namely diffuse large B-cell lymphoma, with a distinct immunophenotype. The Hodgkin-Reed-Sternberg cells were positive for CD15, CD20, CD30, PAX-5 (weak/partial), and EBV (EBERs), and negative for CD45. In contrast, the large B-cells are positive for CD20, PAX-5 (strong), CD45, and CD30 (very focal), and negative for CD15 and EBERs. The large B-cell area had an increased mitotic rate. Taken together, these data indicate that these Hodgkin and the Non-Hodgkin’ lymphomas arose as a consequence of independent malignant transformation events.
