Abstract Rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) therapy is the standard of care for patients with diffuse large B-cell lymphoma (DLBCL). Typically, the dose of rituximab is 375 mg/m2; data obtained from recent clinical trials about the pharmacokinetics of rituximab showed that elderly women have a better outcome than elderly men and a more favorable pharmacokinetics of rituximab than all other patients with DLBCL. Therefore, optimization of the dose and schedule of rituximab is required for the subpopulation of patients with DLBCL that show a fast clearance of rituximab. The metabolism of rituximab, which is mostly excreted through the kidneys, is not completely understood thus far. Renal function, which is determined using creatinine clearance (CCr), at the time of administration may affect the clearance of rituximab, and thus, the therapeutic outcomes. We examined the association between the rate of CCr and survival outcome in patients with DLBCL treated with R-CHOP. We evaluated 653 patients with newly diagnosed de novo DLBCL, excluding those with transformed DLBCL, at the Cancer Institute Hospital of the Japanese Foundation for Cancer Research from January 2005 to December 2015. All patients were treated with R-CHOP or modified regimens. CCr was calculated using the Cockcroft-Gault formula. Tumour staging and response assessment were performed using the revised response criteria for malignant lymphoma and the International Conference on Malignant Lymphomas Imaging Working Group by using positron emission tomography-computed tomography and bone marrow biopsy. Progression-free survival (PFS) and overall survival (OS) were defined as the time from the date of initiation of R-CHOP to the date of disease progression, relapse, last follow-up, or death from lymphoma. Deaths due to reasons other than lymphoma were censored. PFS and OS were estimated using the Kaplan-Meier method, and the differences were compared using the log-rank test. The Cox proportional hazards regression models were used to identify the prognostic factors to predict the PFS and OS. A total of 653 patients with DLBCL were met the inclusion criteria, and the median follow-up for survival was 64 months. Our results showed that 133 (20.3%) patients had a CCr rate less than 60 mL/min. Patients with a low rate of CCr were older, had an advanced stage of DLBCL, extranodal disease, high levels of lactate dehydrogenase (LDH), and high proportion of non-germinal cell (GC) subtype, which are indicators of a poor prognosis. Therefore, patients with a lower rate of CCr showed poorer PFS (5-year PFS 74.2% vs. 80.8%, p = 0.13) and OS (5-year OS 77.1% vs. 86.9%, p=0.013). Further, we performed subgroup analysis according to CCr using the revised International Prognostic Index (R-IPI), which includes of age >60 years, stage III/IV disease, elevated LDH levels, performance status ≥ 2, more than one extranodal site of disease. Although all prognostic groups did not show a significant difference depending on the CCr, the groups with very good and good prognosis showed superior PFS in a low rate of CCr group than high rate of CCr group (Figure 1). The results of subgroup analysis for OS were similar to those observed for PFS. Thus, patients with very good and good prognosis determined using R-IPI may be affected by the subtle difference in the clearance of rituximab, whereas those with poor prognosis may not be affected by this difference. Results of multivariate analysis for PFS and OS showed that a low rate of CCr was not a significant prognostic factor. Thus, our results showed that although CCr may be a factor for clearance of rituximab, no significant association exists between the rate of CCr and survival. Our findings suggest that modification of the dose of rituximab depending on CCr is not recommended for improving survival. Further studies are required to establish an optimal dose and schedule of rituximab in all subgroups of patients with DLBCL.

Purpose To study pharmacokinetics, toxicity, and efficacy of prolonged rituximab exposure in elderly patients with diffuse large B-cell lymphoma (DLBCL). Patients and Methods In the SMARTE-R-CHOP-14 trial, rituximab 375 mg/m2 was administered, together with six cycles of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone on a 14-day schedule (6×R-CHOP-14), on days −4, 0, 10, 29, 57, 99, 155, and 239. Pharmacokinetics and outcome were to be compared with those of patients who had received 6×R-CHOP-14 in combination with eight 2-week applications of rituximab in the RICOVER-60 (Rituximab With CHOP Over Age 60 Years) trial. Results The complete response (CR)/unconfirmed CR rate was 85% in 189 evaluable patients, 90% for 90 good-prognosis patients (International Prognostic Index [IPI], 1 or 2), and 81% for 99 poor-prognosis patients (IPI, 3 to 5); 3-year event-free survival (EFS) was 71%, 75%, and 67%, respectively; and 3-year overall survival (OS) was 84%, 88%, and 80%, respectively, with no differences between men and women. The preplanned historical comparison with 306 RICOVER-60 patients (good prognosis, n = 183; poor prognosis, n = 123) revealed no outcome differences for all and good-prognosis patients; however, the longer exposure time in SMARTE-R-CHOP-14 compared with RICOVER-60 was associated with better 3-year EFS (67% v 54%) and OS (80% v 67%) in poor-prognosis patients. Conclusion Extended rituximab exposure compared with eight 2-week applications in combination with 6×R-CHOP-14 significantly improved outcome of elderly poor-prognosis patients without increasing toxicity. To our knowledge, results obtained with the SMARTE-R-CHOP-14 rituximab schedule are the best reported for elderly patients with DLBCL to date. In the subgroup of poor-prognosis patients treated with extended rituximab exposure, the outcome seemed superior to that of a similar historical cohort of patients treated with 6×R-CHOP-14 plus 2-week rituximab, with similar toxicity. A randomized comparison of the two schedules is warranted.

Myeloid-derived suppressor cells (MDSCs) are defined as negative regulators that suppress the immune response through a variety of mechanisms, which usually cluster in cancer, inflammation, and autoimmune diseases. This study aims to investigate the correlation between M-MDSCs and the clinical features of diffuse large B-cell lymphoma (DLBCL) patients, as well as the possible accumulation mechanism of M-MDSCs. The level of M-MDSCs is significantly increased in newly diagnosed and relapsed DLBCL patients. Regarding newly diagnosed DLBCL patients, the frequency of M-MDSCs is positively correlated with tumor progression and negatively correlated with overall survival (OS). More importantly, the level of M-MDSCs can be defined as a biomarker for a poor prognosis in DLBCL patients. Additionally, interleukin-35 (IL-35) mediates the accumulation of M-MDSCs in DLBCL patients. Anti-IL-35 treatment significantly reduces levels of M-MDSCs in Ly8 tumor-bearing mice. Thus, M-MDSCs are involved in the pathological process of DLBCL. Targeting M-MDSCs may be a promising therapeutic strategy for the treatment of DLBCL patients.

Objective: To evaluate the status of C-MYC protein expression and Ki-67 proliferative index and to clarify their role in predicting relapse of diffuse large B cell lymphoma (DLBL). Materials and Methods: A retrospective study conducted on 50 cases diagnosed as DLBL in a 3 years’ time period from January 2014 till December 2016, collected from the archive of Pathology Departments of the National Cancer Institute Cairo - Egypt, Misr University for Science and Technology and private labs of authors. The diagnosis of DLBL for all cases, both nodal and extranodal, was confirmed by histopathologic examination and immunophenotyping. Automated immunohistochemical staining using antibodies against C-MYC protein and MIB-1 was used to evaluate the C-MYC expression in tumor cells and to assess their proliferative ability by calculating Ki-67 labelling index. The relation between the percentage of C-MYC protein expression, Ki-67 proliferative index, clinical data and the relapse status during the follow up period were analyzed. Results: A total of 50 cases of DLBL in both nodal and extra-nodal sites were included. Twenty-three cases (46%) were expressing the C-MYC protein, and 29 cases (58%) showed high Ki-67 proliferative index. Twenty-two cases (44%) relapsed during the follow-up period. Positive C-MYC protein expression was significantly associated with high Ki-67 proliferative index. C-MYC protein expression and high Ki-67 proliferative index were independently associated with disease relapses in 81.8% and 86.4% of cases respectively. Cases with combined C-MYC protein expression and high Ki-67 proliferative index showed statistical prediction of relapse in 81.8% of cases. Conclusion: C-MYC protein expression and high Ki-67 proliferative index were independently associated with relapse of diffuse large B cell lymphoma. Furthermore, the combined positive C-MYC protein expression and high Ki-67 proliferative index is better than a single positive test in predicting relapses among DLBL patients.

Introduction: The incidence and outcome of Waldenström's macroglobulinemia (WM) patients with transformation to diffuse large B-cell lymphoma (DLBCL) are unclear. We performed a retrospective analysis to determine the incidence, clinicopathological characteristics and treatment outcome of WM patient with histologic transformation to DLBCL in our centre. Methods: Single centre chart review of WM patients in the past 10 years. Patients with histologic diagnosis of DLBCL after the diagnosis WM were included in our analysis. Results: Three of the 79 WM patients had histological transformation to DLBCL, two male and one female. Mean age at DLBCL development was 76,6 years. The mean time to transformation since diagnosis of WM was 8,3 years (14, 8 and 3 years). All three patients received at least one prior line of treatment in relation to WM (2, 1 and 3 prior lines). Different regimens used were cyclophosphamide/dexamethasone, rituximab/bendamustin, chlorambucil monotherapy, fludarabine monotherapy, R-CVP and ibrutinib monotherapy. The patients were in clinical CR from WM at the time of transformation, two patients were still on treatment. All three patients presented with advanced disease (stage IIIB, IVB, and IVA) non-GCB subtype DLBCL with at least 2 extra nodal sites. R-IPI scores were 4,5 and 4. Two patients were treated with R-miniCHOP, one patient received R-CHOP. The first patient achieved a CR at the end of treatment and is now 1,5 years in follow-up. The second patient died from pneumonia one year after achieving a CR. The third patient is in follow op since 3 months after reaching a CR at the end of treatment. Conclusion: Over the past decade transformation of WM to DLBCL was 3.7% in our centre. This is in accordance with previous data suggesting an 2.4% risk of transformation over 10 years.Time to transformation varies and no association with prior WM therapy and response to treatment can be found.All patients presented with more aggressive DLBCL in an advanced stage.All three patients achieved a CR following treatment for DLBCL, one patient died from pneumonia, two others are now in follow-up 1,5 years and 3 months respectively.

Introduction: Large B-cell lymphoma (LBCL) is the most common subtype of non-Hodgkin lymphoma. Frontline treatment is curative in ~60% of patients (pts); however, ~30% of pts relapse and ~10% are refractory to frontline treatment. Treatment options for pts with relapsed/refractory (R/R) disease, especially in the third-line or greater (3L+) setting, have been primarily salvage chemotherapies (CTs). Recently, 2 CAR T cell products, axicabtagene ciloleucel (Yescarta®) and tisagenlecleucel (Kymriah®), and the antibody-drug conjugate, polatuzumab vedotin (Polivy®), were approved in the 3L setting. A systematic literature review (SLR) of R/R LBCL was conducted to identify relevant evidence on clinical outcomes in LBCL pts, including these new therapies, within the second-line and greater (2L+) or 3L+ setting, and to define the unmet medical need. Methods: This SLR was conducted in accordance with the Cochrane Handbook for Systematic Reviews of Interventions and European Union Health Technology Assessment requirements. The review identified randomized and nonrandomized/observational studies within R/R LBCL, including diffuse large B-cell lymphoma (DLBCL), follicular lymphoma grade 3B (FL3B), primary mediastinal large B-cell lymphoma (PMBCL), DLBCL transformed from indolent lymphomas, and R/R DLBCL with secondary central nervous system (SCNS) involvement. Sources were EMBASE, MEDLINE, The Cochrane Library, and clinical conferences (ASCO, ESMO, EHA, ASH, ICML, AACR, and EORTC) from Jan 2000 to Apr 2019. Results : Following screening of 8683 database records and additional sources, 103 publications covering 78 unique studies were identified. Studies identified were characterized by line of treatment and R/R LBCL subtype (Figure). OS, PFS, DOR, OR, and safety observed from the identified studies were described. Disease subtypes, pt eligibility criteria, and length of follow-up varied notably across studies. In the 3L+ population, 11 salvage CT and 2 CAR T cell therapy studies reported survival outcomes. With salvage CT, the reported ORR across studies ranged from 0% to 54%, while CR ranged from 5.6%-31%. Median OS (mOS) ranged between 3-9 months, with one outlying study reporting mOS at 20 months. Median PFS (mPFS) reported within the salvage CT studies ranged from 2-6 months. Among CAR T cell therapies, pts treated with axicabtagene ciloleucel (n=101) reported a CR rate of 58% and median DOR (mDOR) was 11.1 months after a median follow-up of 27.1 months. mPFS was 5.9 months and mOS was not reached. At a median follow-up of 19.3 months, pts treated with tisagenlecleucel (n=115) had a CR of 40% but the mDOR was not reached. mOS was 11.1 months for all infused patients. In the 2L+ transplant-eligible population (36 studies), pts who received high-dose CT + HSCT achieved mOS between 9 months to 5 years. In the transplant noneligible population, 16 studies reported mOS between 3-20 months. Studies involving mixed transplant-eligible and noneligible populations (30 studies) reported mOS of 1-17 months. A few studies with limited sample sizes were found to report outcomes in LBCL subtypes (eg, PMBCL, SCNS lymphoma, DLBCL transformed from non-FL indolent lymphoma, FL3B). In the 3L+ setting, 1 study reported that mOS was not reached after a median of 6.6 months. In the 2L+ setting, 4 studies reported mPFS and mOS outcomes ranging between 2-9 months and 10-16 months, respectively. Among studies assessing safety of salvage CTs in R/R LBCL, neutropenia, leukocytopenia, thrombocytopenia, and infections were the most commonly reported adverse events (AEs), with neutropenia being the most reported. Among the 3 studies reporting safety outcomes of CAR T cell therapy, data suggest that hematologic AEs (possibly related to lymphodepleting CT), cytokine release syndrome, and neurotoxicity are the most reported. Conclusions : Despite the availability of new therapies for 2L+ and 3L + LBCL, examination of the current evidence has shown that there exists a high unmet need for additional therapeutic options that provide favorable benefit/risk and durable response for these patients. Furthermore, limited data are available for the rarer subtypes of LBCL. Both findings represent important treatment gaps for R/R LBCL that must be addressed in future research geared toward improvement of the current treatment landscape.

Background/Aims: Rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) every 14 days seems to achieve better outcomes than R-CHOP every 21 days in diffuse large B-cell lymphoma (DLBCL) patients. Currently, the standard regimen is R-CHOP every 21 days. Methods: This is a phase II clinical trial of treatment with 6 cycles of R-CHOP-14 with pegfilgrastim support in 2 populations of previously untreated DLBCL patients aged ≥65 years (n = 73) or <65 years (n = 51) with low-risk International Prognostic Index scores (0-2). Results: With a median follow-up of 63.7 months, the 5-year event-free survival rate was 53.8% in patients aged ≥65 years and 71.0% in patients aged <65 years. The 5-year overall survival rate was 71.4 and 89.8%, respectively. The complete remission rate was 69.9% for older and 80.4% for younger patients. The median relative dose intensity of cytotoxic drugs was 143.2% in the elderly and 149.1% in the young patients. Febrile neutropenia was the most common grade 3-4 adverse event, being higher in elderly patients (21.3 vs. 9.3%). Eight deaths (7 in elderly patients) were considered treatment related. Conclusion: In conclusion, the R-CHOP-14 regimen is feasible and very active, though it is more toxic in elderly patients mainly due to an increased incidence of infections. New strategies, such as new monoclonal antibodies or new targeted therapies, are needed to improve the outcomes of DLBCL patients.

Primary breast diffuse large B-cell lymphoma (DLBCL) is a rare non-Hodgkin’s lymphoma with limited data. We here report a case of primary breast diffuse large B-cell lymphoma mimicking breast cancer. A 52-year-old woman had a painless mass in her right breast. Fine needle aspiration cytology and core biopsy were performed which suggested malignant features but could not confirm the specific subtype. Excisional biopsy then was conducted revealing non-Hodgkin lymphoma, which was subsequently confirmed with histopathology and diagnosed as diffuse large B-cell lymphoma (DLBCL). A chest computed tomography scan revealed a 3.5 cm sized breast mass with skin thickening and modest lymphadenopathy in the ipsilateral axilla. The patient received six courses of R-CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone plus rituximab) chemotherapy, then whole breast radiation (30Gy in 15 fractions). At 12 months of follow-up, the patient survives with no evidence of disease. No morbidities occurred in this patient during the follow-up period. We briefly review the current practice pattern in patients with primary breast diffuse large B-cell lymphoma.
