Abstract
Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma, accounting for around 30-60% of all cases. The management of DLBCL in Asia has several unmet needs due to the diversity of the population, the heterogeneity of local clinical guidelines for DLBCL and the wide disparity in resources and healthcare systems across different regions. Rituximab combined with cyclophosphamide, doxorubicin, vincristine, and prednisone (RCHOP) is widely recognized as the standard first-line treatment for DLBCL; however, alternative regimens are required to improve patient outcomes in challenging subtypes, such as patients with high International Prognostic Index scores, old/frail patients, and patients with double-hit and double-expressor DLBCL or concurrent central nervous system disease. This review article draws from the expertise of practicing hematologists/oncologists in the region, with the aim of integrating data from current scientific evidence to address the unmet needs and unique socioeconomic challenges faced by challenging high risk patient groups in the Asia-Pacific region.

High G9a Expression in DLBCL and Its Inhibition by Niclosamide to Induce Autophagy as a Therapeutic Approach. Cancers (Basel) 2023; 15:4150. [PMID: 37627178 PMCID: PMC10452841 DOI: 10.3390/cancers15164150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 08/14/2023] [Accepted: 08/15/2023] [Indexed: 08/27/2023] Open
Abstract
BACKGROUND Diffuse large B-cell lymphoma (DLBCL) is a malignant lymphoid tumor disease that is characterized by heterogeneity, but current treatment does not benefit all patients, which highlights the need to identify oncogenic genes and appropriate drugs. G9a is a histone methyltransferase that catalyzes histone H3 lysine 9 (H3K9) methylation to regulate gene function and expression in various cancers. METHODS TCGA and GTEx data were analyzed using the GEPIA2 platform. Cell viability under drug treatment was assessed using Alamar Blue reagent; the interaction between G9a and niclosamide was assessed using molecular docking analysis; mRNA and protein expression were quantified in DLBCL cell lines. Finally, G9a expression was quantified in 39 DLBCL patient samples. RESULTS The TCGA database analysis revealed higher G9a mRNA expression in DLBCL compared to normal tissues. Niclosamide inhibited DLBCL cell line proliferation in a time- and dose-dependent manner, reducing G9a expression and increasing p62, BECN1, and LC3 gene expression by autophagy pathway regulation. There was a correlation between G9a expression in DLBCL samples and clinical data, showing that advanced cancer stages exhibited a higher proportion of G9a-expressing cells. CONCLUSION G9a overexpression is associated with tumor progression in DLBCL. Niclosamide effectively inhibits DLBCL growth by reducing G9a expression via the cellular autophagy pathway; therefore, G9a is a potential molecular target for the development of therapeutic strategies for DLBCL.

Abstract
Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma (NHL); it has a cure rate of approximately 50% with standard anthracycline-based chemoimmunotherapy. However, the clinical outcomes of elderly unfit/frail DLBCL patients remain suboptimal due to poor tolerance of anthracycline-containing regimens. Herein, we report a series of seven elderly unfit patients with DLBCL who were treated with a reduced-intensity anthracycline-free chemoimmunotherapy (rituximab, cyclophosphamide, vincristine, and prednisone) regimen combined with lenalidomide (R2-COP). Five patients received R2-COP as first-line therapy, and two patients were treated for relapsed DLBCL. Four patients with newly diagnosed DLBCL and two with relapsed disease achieved complete remission. The R2-COP regimen was well tolerated. Interim positron emission tomography (PET) scans in four patients after two to three cycles showed a complete metabolic response. At a median follow-up of 24 months, six patients remain in complete remission. R2-COP is an effective anthracycline-free regimen with encouraging clinical activity in elderly DLBCL patients who are unfit for standard anthracycline-containing regimens.

Real-World Estimation of First- and Second-Line Treatments for Diffuse Large B-Cell Lymphoma Using Health Insurance Data: A Belgian Population-Based Study. Front Oncol 2022; 12:824704. [PMID: 35299736 PMCID: PMC8922541 DOI: 10.3389/fonc.2022.824704] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Accepted: 01/27/2022] [Indexed: 11/13/2022] Open
Abstract
We determined first- and second-line regimens, including hematopoietic stem cell transplantations, in all diffuse large B cell lymphoma (DLBCL) patients aged ≥20 yr (n = 1,888), registered at the Belgian Cancer Registry (2013–2015). Treatments were inferred from reimbursed drugs, and procedures registered in national health insurance databases. This real-world population-based study allows to assess patients usually excluded from clinical trials such as those with comorbidities, other malignancies (12%), and advanced age (28% are ≥80 yr old). Our data show that the majority of older patients are still started on first-line regimens with curative intent and a substantial proportion of them benefit from this approach. First-line treatments included full R-CHOP (44%), “incomplete” (R-)CHOP (18%), other anthracycline (14%), non-anthracycline (9%), only radiotherapy (3%), and no chemo-/radiotherapy (13%), with significant variation between age groups. The 5-year overall survival (OS) of all patients was 56% with a clear influence of age (78% [20–59 yr] versus 16% [≥85 yr]) and of the type of first-line treatments: full R-CHOP (72%), other anthracycline (58%), “incomplete” (R-)CHOP (47%), non-anthracycline (30%), only radiotherapy (30%), and no chemo-/radiotherapy (9%). Second-line therapy, presumed for refractory (7%) or relapsed disease (9%), was initiated in 252 patients (16%) and was predominantly (71%) platinum-based. The 5-year OS after second-line treatment without autologous stem cell transplantation (ASCT) was generally poor (11% in ≥70 yr versus 17% in <70 yr). An ASCT was performed in 5% of treated patients (n = 82). The 5-year OS after first- or second-line ASCT was similar (69% versus 66%). After adjustment, multivariable OS analyses indicated a significant hazard ratio (HR) for, among others, age (HR 1.81 to 5.95 for increasing age), performance status (PS) (HR 4.56 for PS >1 within 3 months from incidence), subsequent malignancies (HR 2.50), prior malignancies (HR 1.34), respiratory and diabetic comorbidity (HR 1.41 and 1.24), gender (HR 1.25 for males), and first-line treatment with full R-CHOP (HR 0.41) or other anthracycline-containing regimens (HR 0.72). Despite inherent limitations, patterns of care in DLBCL could be determined using an innovative approach based on Belgian health insurance data.

Abstract
Primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is rare, and the optimal frontline treatment has not taken shape so far. It is still debatable whether the watch-and-wait (W&W) policy is beneficial to patients, especially in the early stage. This study was to compare the efficacy of W&W with rituximab single agent or combined chemotherapy (R/R-Chemo) on primary pulmonary MALT patients with localized disease. Clinical characters and effect on 28 patients with primary pulmonary MALT (IE phase) were analyzed. Among the 28 patients, 14 were grouped into W&W cohort, and 14 were immediately treated with R/R-Chemo. The median follow-up duration was 62 months. The estimated median time to treatment failure (TTF) in the W&W cohort and immediate R/R-Chemo cohort was 29 months and 59 months, which were not significantly different (P = 0.667). The estimated median time of overall survival (OS) in the W&W cohort and immediate R/R-Chemo cohort was 78 months and 76 months, which were also not statistically significant (P = 0.696). Concerning prognosis, there is no difference between patients with primary pulmonary MALT (IE phase) treated with W&W and with timely R/R-Chemo.

Abstract
Treating unfit patients with aggressive B-cell lymphoma poses the dilemma of balancing potential cure while minimizing toxicity because of frailty and comorbidities. Age greater than 80 years and common comorbidities such as cardiovascular disease and poorly controlled diabetes mellitus often preclude the use of full-dose anthracyclines and steroids, the backbones of standard regimens for aggressive B-cell lymphomas. Assessing patient fitness remains subjective, with no consensus on best practice or how to integrate assessment tools into decision making. Incorporation of prephase steroids for all unfit patients may markedly improve performance status with consideration of standard dose therapy, especially in patients less than age 80. Although randomized studies are lacking, current data suggest patients age ≥ 80 years are considered unfit a priori and should receive dose-reduced anthracycline regimens or anthracycline-free regimens. Severe toxicity is highest after the first cycle of chemotherapy. Dose reductions for cycle 1 in unfit patients with plans to escalate as tolerated is often an effective strategy. Unfit patients often benefit from comanagement with gerontologists, cardio-oncologists, and endocrinologists depending on age and the nature of comorbidities. Palliative therapy for patients with newly diagnosed aggressive B-cell lymphoma results in median survivals of less than 3 months, and in general, should only be considered in patients with untreatable comorbidities such as advanced dementia or refractory metastatic solid tumors. Incorporating new, potentially less toxic agents such as novel antibodies, antibody-drug conjugates, and bispecific antibodies into first-line therapy is an exciting future direction with potential for substantial benefit in less fit patients.
