Background: The current standard therapy for patients with diffuse large B-cell lymphoma (DLBCL) is rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone (RCHOP). The role of radiotherapy (RT) after complete response (CR) to RCHOP in patients with DLBCL remains unclear. This systematic review with a meta-analysis is an attempt to evaluate this role. Methods: Studies that evaluated RT versus no-RT after CR to RCHOP for DLBCL patients were searched in databases. Hazard ratios (HR) with their respective 95% confidence intervals (CI) were calculated using a random-effects model. Results: A total of 4 qualified retrospective studies (633 patients) were included in this review. The results suggested that RT improved overall survival (OS; HR 0.33, 95% CI 0.14-0.77) and progression-free/event-free survival (PFS/EFS; HR 0.24, 95% CI 0.11-0.50) in all patients compared with no-RT. In a subgroup analysis of patients with stage III-IV DLBCL, RT improved PFS/EFS (HR 0.19, 95% CI 0.07-0.51) and local control (HR 0.12, 95% CI 0.03-0.44), with a trend of improving OS (HR 0.35, 95% CI 0.12-1.05). Conclusion: Consolidation RT could significantly improve outcomes of DLBCL patients who achieved a CR to RCHOP. However, the significance of these results was limited by these retrospective data. Further investigation of the role of consolidation RT in the rituximab era is needed.

Abstract Aim: Composite histologies of diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL) may be present synchronously at diagnosis or metachronously at the time of transformation of a formerly diagnosed FL. The aim of this study was to examine their clinico-pathological characteristics and treatment outcomes. Method: Patients who were consecutively diagnosed with composite FL/DLBCL (n=120) and FL (n=346) from 2001-2017 at the National Cancer Centre Singapore were retrospectively analyzed. Chi-squared tests and multivariate logistic regression were performed to evaluate clinico-pathological associations between the two cohorts. Survival analysis was performed using the Kaplan-Meier method and the log-rank test. Results: Amongst the FL cases, 21 patients (6.1%) with metachronous transformed FL/DLBCL were identified. The median lag time from diagnosis of FL to DLBCL transformation was 47 months (range, 7.8-168). Clinico-pathological features in synchronous and metachronous FL/DLBCL were similar, with both entities demonstrating a male preponderance (67% male and 33% female). Median age at diagnosis was 67 years (range, 41-81) and 60 years (range, 24-90) for metachronous and synchronous FL/DLBCL, respectively. The cell-of-origin by Han's criteria was similar (metachronous: GCB 52%, ABC 43%, unknown 5%; synchronous: GCB 38%, ABC 57%, unknown 5%; p = 0.21), as were the occurrence of C-MYC/BCL2/BCL6 double-hit rearrangements. However, survival from the time of DLBCL development was significantly worse (median, 3 vs 12 years) for metachronous compared to synchronous FL/DLBCL (HR 2.20, 95%CI 0.88-5.49, p = 0.022). Double-hit, advanced stage, and use of non-RCHOP regimens (OR 7.54, 95%CI 2.84-20.1, p = 0.0001) were associated with lack of complete response to chemotherapy. In metachronous FL/DLBCL, the R-CHOP regimen was less commonly used (77% vs 56%, p = 0.049). Correspondingly, complete response to chemotherapy was less likely in metachronous cases (38% vs 63%, p = 0.037). Conclusion: Metachronous and synchronous FL/DLBCL share similar clinico-pathological characteristics. A preceding diagnosis of FL however, predicts for significantly worse survival outcomes and suboptimal responses to chemotherapy. Disclosures No relevant conflicts of interest to declare.

8082 Background: Absolute lymphocyte counts (ALCs) at diagnosis has been shown to be an independent prognostic factor in patients with follicular lymphoma (FL) although the precise mechanism was not fully elucidated. The current study evaluated the impact of Absolute lymphocyte counts (ALCs) at diagnosis in patients with diffuse large B-cell lymphoma (DLBCL) on the response to chemotherapy and survival. Methods: The treatment outcomes of the patients receiving CHOP (n=101) or R-CHOP chemotherapy (n=122) were compared according to ALCs at diagnosis (<1.0 vs. = 1.0×109/L). Results: Forty-two patients (19%) had a lower ALC count at diagnosis (CHOP, 23 [23%]; R-CHOP, 19 [16%]). The lower ALCs showed a good correlation with IPI (p<0.001), performance (p<0.001), LDH (p<0.001), stage (p=0.004), extranodal involvement (p=0.011), but not with age or sex. A significant difference of response rate was noted according to ALCs in favor of a higher ALCs (CR: 80% vs. 60%, p=0.005; ORR: 93% vs. 78%, p=0.003). In addition, event-free survival (EFS) was worse in a lower ALC group than higher ALC group: median duration of EFS, 1,773 days vs. 326 days (p<0.001). The OS was also in favor of a higher ALC group: median duration of OS, 3,000 days vs. 695 days (p<0.001). In multivariate analysis, ALC at diagnosis was an independent predictive factor for CR (HR 2.717, p=0.009) and prognostic factor for EFS (HR 2.148, p=0.004) or OS (HR 2.863, p=0.002). Conclusion: The ALCs at diagnosis appears to predict the survival of DLBCL patients. Our findings suggested that the ALCs at diagnosis may reflect host's immune status against DLBCL, implying that immune system of host will play a critical role on survival of DLBCL patients.
