Treatment Modalities and Survival Outcomes for Sinonasal Diffuse Large B-Cell Lymphoma.

ABSTRACT:

Objectives/hypothesis

This study utilizes a large population national database to comprehensively analyze prognosticators and overall survival (OS) outcomes of varying treatment modalities in a large cohort of sinonasal diffuse large B-cell lymphoma (SN-DLBCL) patients.

Study design

Retrospective database study.

Methods

The National Cancer Database was queried for all SN-DLBCL cases diagnosed from 2004 to 2015. Kaplan-Meier log-rank test determined differences in OS based on clinical covariates. Cox proportional-hazards analysis was used to determine clinical and sociodemographic covariates predictive of mortality.

Results

A total of 2,073 SN-DLBCL patients were included, consisting of 48% female with a mean age of 66.0 ± 16.2 years. Overall, 82% of patients were Caucasian, 74% had early-stage disease, and 49% had primary tumors in the paranasal sinuses. Early-stage patients were more likely to receive multi-agent chemoradiotherapy compared to multi-agent chemotherapy alone (P < .001). Multivariable Cox proportional-hazards analysis revealed chemoradiotherapy to confer significantly greater OS improvements than chemotherapy alone (hazard ratio [HR]: 0.61; P < .001). However, subset analysis of late-stage patients demonstrated no significant differences in OS between these treatment modalities (P = .245). On multivariable analysis of chemotherapy patients treated post-2012, immunotherapy (HR = 0.51; P = .024) demonstrated significant OS benefits. However, subset analysis showed no significant advantage in OS with administering immunotherapy for late-stage patients (P = .326). Lastly, for all patients treated post-2012, those receiving immunotherapy had significantly improved OS compared to those not receiving immunotherapy (P < .001).

Conclusions

Treatment protocol selection differs between early- and late-stage SN-DLBCL patients. Early-stage patients receiving chemotherapy may benefit from immunotherapy as part of their treatment paradigm.

Project description:BackgroundDiffuse large B-cell lymphoma (DLBCL) constitutes 30% of all non-Hodgkin's lymphomas. It can present as a nodal disease or as an extra nodal disease. Based on the site of origin, extra nodal DLBCL (EN-DLBCL) may have a distinct clinical outcome. Apart from the site of origin, factors including demographics, stage, and presence of any other primary malignancy also affect the outcome. The purpose of our study was to characterize prognostically distinct groups based on the site of presentation of EN-DLBCL.MethodsWe used 18 registries in Surveillance, Epidemiology, and End Results database to identify the patients with EN-DLBCL for 2000 - 2015 with last follow-up till December 31, 2018. A total of 30,290 EN-DLBCL patients were selected and categorized based on 13 broad sites grouping. Demographic variables were summarized. We did overall survival analysis with univariate and multivariate Cox-proportional hazard modeling. Short-term survival trend was calculated as well.ResultsThe percentage of EN-DLBCL of all DLBCLs is 34.48%. EN-DLBCL was comparatively seen more in males (54.94%) and non-Hispanic whites (71.52%). In terms of clinical characteristics, patients with EN-DLBCL were mostly diagnosed at age ≥ 60 years (66.11%), early stage (69.33%), and presentation as first primary cancer (81.89%). A higher risk of mortality was seen in non-Hispanic black (hazard ratio (HR) 1.36), with late age of onset (HR 2.69), late stage at presentation (HR 1.42), and with history of other malignancy (HR 1.29). Compared to the intestinal tract, the risk of overall mortality was higher in individuals with involvement of nervous system (HR 1.85), pancreas and hepatobiliary system (HR 1.22), and respiratory system (HR 1.18) and the best outcomes were seen in heart and mediastinal site (HR 0.58) of DLBCL.ConclusionBased upon our population-based study, we conclude that primary site of presentation of EN-DLBCL is an important prognostic factor with significant difference in survival based on histological and epidemiological characteristics.

Project description:BACKGROUNDChronotherapy is a drug intervention at specific times of the day to optimize efficacy and minimize adverse effects. Its value in hematologic malignancy remains to be explored, in particular in adult patients.METHODSWe performed chronotherapeutic analysis using 2 cohorts of patients with diffuse large B cell lymphoma (DLBCL) undergoing chemotherapy with a dichotomized schedule (morning or afternoon). The effect of a morning or afternoon schedule of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) on survival and drug tolerability was evaluated in a survival cohort (n = 210) and an adverse event cohort (n = 129), respectively. Analysis of about 14,000 healthy individuals followed to identify the circadian variation in hematologic parameters.RESULTSBoth progression-free survival (PFS) and overall survival (OS) of female, but not male, patients were significantly shorter when patients received chemotherapy mostly in the morning (PFS HR 0.357, P = 0.033; and OS HR 0.141, P = 0.032). The dose intensity was reduced in female patients treated in the morning (cyclophosphamide 10%, P = 0.002; doxorubicin 8%, P = 0.002; and rituximab 7%, P = 0.003). This was mainly attributable to infection and neutropenic fever: female patients treated in the morning had a higher incidence of infections (16.7% vs. 2.4%) and febrile neutropenia (20.8% vs. 9.8%) as compared with those treated in the afternoon. The sex-specific chronotherapeutic effects can be explained by the larger daily fluctuation of circulating leukocytes and neutrophils in female than in male patients.CONCLUSIONIn female DLBCL patients, R-CHOP treatment in the afternoon can reduce toxicity while it improves efficacy and survival outcome.FUNDINGNational Research Foundation of Korea (NRF) grant funded by the Korean government (grant number NRF-2021R1A4A2001553), Institute for Basic Science IBS-R029-C3, and Human Frontiers Science Program Organization Grant RGY0063/2017.

Project description:BackgroundDiffuse large B-cell lymphoma (DLBCL) of the head-and-neck area primarily involves the Waldeyer ring (WR) and sinonasal area (SN). However, the differential clinical outcomes between patients with WR-DLBCL and those with SN-DLBCL in the rituximab era remain unclear.MethodsTo avoid confounding factors contributed by advanced DLBCL with WR and SN involvement, we assessed the clinical outcomes of patients with stage I/II WR-DLBCL and SN-DLBCL and compared them with those having corresponding stages of DLBCL in the lymph nodes but without other extranodal involvement (LN-DLBCL) in the same period. We compared the patients' clinical characteristics, treatment modalities, event-free survival (EFS), and overall survival (OS) among the three subgroups.ResultsWe analyzed 67, 15, and 106 patients with WR-DLBCL, SN-DLBCL, and LN-DLBCL, respectively, between January 2000 and December 2019. All patients received front-line rituximab-based regimens, and > 80% received rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone-based regimens. More patients with SN-DLBCL had revised International Prognostic Index (R-IPI) score 3 (27%) when compared with those with WR-DLBCL (7%) and those with LN-DLBCL (10%, p = 0.181). Patients with WR-DLBCL, LN-DLBCL, and SN-DLBCL had 5-year EFS and OS rates of 80.7%, 59.5%, and 41.9% (p = 0.021) and 83.7%, 70.8%, and 55.8% (p = 0.032), respectively. Compared to patients with LN-DLBCL, those with WR-DLBCL also had a significantly favorable 5-year EFS rate (p = 0.021) and 5-year OS rate (p = 0.023). Three of the 15 patients with SN-DLBCL experienced lymphoma recurrence in the brain after front-line treatment. In multivariate analyses, R-IPI scores of 1-2 and 3 served as significantly poor prognostic factors for patients with poor EFS and OS.ConclusionsCompared to patients with LN-DLBCL, patients with WR-DLBCL receiving front-line rituximab-based treatments had favorable clinical outcomes; however, patients with SN-DLBCL had worse clinical outcomes. Further studies on molecular prognostic factors and treatment strategies for SN-DLBCL are warranted.

Project description:BackgroundThe prognostic significance of extranodal sites in stage IV diffuse large B-cell lymphoma (DLBCL) remains uncertain, making it challenging to select appropriate treatment strategies for individual patients. In this study, we aimed to evaluate the influence of different extranodal sites on prognosis in young patients with stage IV DLBCL who achieved complete remission (CR) following initial chemo-immunotherapy and to explore the potential of autologous hematopoietic stem cell transplantation (ASCT) as a consolidation treatment for specific patient subgroups.MethodsWe retrospectively reviewed data from 119 patients with DLBCL aged < 60 years who achieved CR after chemo-immunotherapy between 2008 and 2020. Patient survival rates were analyzed in correlation with different extranodal sites using univariate and multivariate models. Additionally, we assessed the effect of ASCT on 5-year progression-free survival (PFS) and overall survival (OS) in patients with different extranodal sites involved.Study designA retrospective bicenter study.ResultsUnivariate analysis revealed a significant decrease in survival rates in patients with a Deauville score of 3 and those with extranodal DLBCL affecting the spleen, bone marrow, nasosinus, and liver. In multivariate analysis, only nasosinusal involvement remained a significant predictor of reduced OS. Patients with spleen involvement benefited significantly from ASCT in terms of 5-year PFS and OS, whereas those with nasosinusal involvement did not demonstrate any survival advantage with ASCT.ConclusionOur findings highlight the influence of specific extranodal sites on the prognosis of patients with stage IV DLBCL. The data indicate a clear need for precise patient stratification based on extranodal involvement for more effective treatment planning. Notably, patients with spleen involvement appear to benefit from ASCT, suggesting that this strategy could be useful in this subgroup. Further prospective studies are needed to confirm and incorporate these findings into clinical practice.
