Abstract
We herein report a case of diffuse large B-cell lymphoma (DLBCL) involving multiple renal and bone infiltrations presenting with giant cell arteritis (GCA)-like manifestations. One month prior, the present patient had left-sided temporal headache, jaw claudication, and renal failure. The patient was diagnosed with DLBCL based on a renal biopsy. After rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone plus intrathecal methotrexate/cytarabine/prednisone and rituximab, high-dose methotrexate, and cytarabine chemotherapy, the patient's clinical manifestations improved, and complete remission was achieved. DLBCL rarely but occasionally presents with GCA-like manifestations or multiple renal and bone infiltrations, highlighting the need for prompt and aggressive combination chemotherapy.

Abstract
Advanced diffuse large B cell lymphoma (DLBCL) is a common malignant tumor with aggressive clinical features and poor prognosis. At present, there is lack of effective prognostic tool for patients with advanced (stage III/IV) DLBCL. The aim of this study is to identify prognostic indicators that affect survival and response and establish the first survival prediction nomogram for advanced DLBCL. A total of 402 patients with advanced DLBCL were enrolled in this study. COX multivariate analysis was used to obtain independent prognostic factors. The independent prognostic factors were included in the nomogram, and the nomogram to predict the performance of the model was established by R rms package, C-index (consistency index), AUC curve and calibration curve. The training and validation cohorts included 281 and 121 patients. In the training cohort, multivariate analysis showed that Ki-67 (70% (high expression) vs ≤ 70% (low expression), p < 0.001), LDH (lactate dehydrogenase) (elevated vs normal, p = 0.05), FER (ferritin) (elevated vs normal, p < 0.001), and β2-microglobulin (elevated vs normal, p < 0.001) were independent predictors and the nomogram was constructed. The nomogram showed that there was a significant difference in OS among the low-risk, intermediate-risk and high-risk groups, with 5-year survival rates of 81.6%, 44% and 6%, respectively. The C-index of the nomogram in the training group was 0.76. The internal validation of the training group showed good consistency. In the internal validation cohort of the training group, the AUC was 0.828, and similar results were obtained in the validation group, with a C-index of 0.74 and an AUC of 0.803. The proposed nomogram provided a valuable individualized risk assessment of OS in advanced DLBCL patients.

LncRNA CHROMR/miR-27b-3p/MET axis promotes the proliferation, invasion, and contributes to rituximab resistance in diffuse large B-cell lymphoma. J Biol Chem 2024; 300:105762. [PMID: 38367665 PMCID: PMC10940993 DOI: 10.1016/j.jbc.2024.105762] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 01/11/2024] [Accepted: 02/05/2024] [Indexed: 02/19/2024] Open
Abstract
Long non-coding RNAs (LncRNAs) could regulate chemoresistance through sponging microRNAs (miRNAs) and sequestering RNA binding proteins. However, the mechanism of lncRNAs in rituximab resistance in diffuse large B-cell lymphoma (DLBCL) is largely unknown. Here, we investigated the functions and molecular mechanisms of lncRNA CHROMR in DLBCL tumorigenesis and chemoresistance. LncRNA CHROMR is highly expressed in DLBCL tissues and cells. We examined the oncogenic functions of lncRNA CHROMR in DLBCL by a panel of gain-or-loss-of-function assays and in vitro experiments. LncRNA CHROMR suppression promotes CD20 transcription in DLBCL cells and inhibits rituximab resistance. RNA immunoprecipitation, RNA pull-down, and dual luciferase reporter assay reveal that lncRNA CHROMR sponges with miR-27b-3p to regulate mesenchymal-epithelial transition factor (MET) levels and Akt signaling in DLBCL cells. Targeting the lncRNA CHROMR/miR-27b-3p/MET axis reduces DLBCL tumorigenesis. Altogether, these findings provide a new regulatory model, lncRNA CHROMR/miR-27b-3p/MET, which can serve as a potential therapeutic target for DLBCL.

Abstract
A 59-year-old woman diagnosed with a Grade I chondrosarcoma in T7 underwent total en bloc vertebrectomy. Analysis of the surgical piece established diagnosis of a Grade 1 chondrosarcoma confined to T7. Surprisingly, an infiltration with diffuse large B-cell lymphoma was found. Systemic disease was ruled out and diagnosis was established as intracompartmental Grade 1 chondrosarcoma colliding with intraosseous extranodal diffuse large B-cell lymphoma. Resection of chondrosarcoma was considered complete and treatment with four cycles of RCHOP was indicated. Two years after surgery, the patient remains at complete metabolic response. To date, this is the first reported case of chondrosarcoma colliding with lymphoma. Although Grade 1 chondrosarcoma is typically managed with local control through complete surgical resection, the mentioned finding of the lymphoma indicated the need for systemic treatment with immunochemotherapy.

Abstract
BACKGROUND The introduction of rituximab significantly improved the prognosis of diffuse large B-cell lymphoma (DLBCL), emphasizing the importance of evaluating the long-term consequences of exposure to radiotherapy, alkylating agents and anthracycline-containing (immuno)chemotherapy among DLBCL survivors. METHODS Long-term risk of subsequent malignant neoplasms (SMNs) was examined in a multicenter cohort comprising 2373 5-year DLBCL survivors treated at ages 15-61 years in 1989-2012. Observed SMN numbers were compared with expected cancer incidence to estimate standardized incidence ratios (SIRs) and absolute excess risks (AERs/10 000 person-years). Treatment-specific risks were assessed using multivariable Cox regression. RESULTS After a median follow-up of 13.8 years, 321 survivors developed one or more SMNs (SIR 1.5, 95% CI 1.3-1.8, AER 51.8). SIRs remained increased for at least 20 years after first-line treatment (SIR ≥20-year follow-up 1.5, 95% CI 1.0-2.2, AER 81.8) and were highest among patients ≤40 years at first DLBCL treatment (SIR 2.7, 95% CI 2.0-3.5). Lung (SIR 2.0, 95% CI 1.5-2.7, AER 13.4) and gastrointestinal cancers (SIR 1.5, 95% CI 1.2-2.0, AER 11.8) accounted for the largest excess risks. Treatment with >4500 mg/m2 cyclophosphamide/>300 mg/m2 doxorubicin versus ≤2250 mg/m2/≤150 mg/m2, respectively, was associated with increased solid SMN risk (hazard ratio 1.5, 95% CI 1.0-2.2). Survivors who received rituximab had a lower risk of subdiaphragmatic solid SMNs (hazard ratio 0.5, 95% CI 0.3-1.0) compared with survivors who did not receive rituximab. CONCLUSION Five-year DLBCL survivors have an increased risk of SMNs. Risks were higher for survivors ≤40 years at first treatment and survivors treated with >4500 mg/m2 cyclophosphamide/>300 mg/m2 doxorubicin, and may be lower for survivors treated in the rituximab era, emphasizing the need for studies with longer follow-up for rituximab-treated patients.

Primary breast diffuse large B-cell lymphoma characterized by CNS relapse and successful hematopoietic stem cell transplantation salvage therapy. J Formos Med Assoc 2024:S0929-6646(24)00053-6. [PMID: 38296697 DOI: 10.1016/j.jfma.2024.01.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 01/02/2024] [Accepted: 01/20/2024] [Indexed: 02/02/2024] Open
Abstract
BACKGROUND Primary breast diffuse large B-cell lymphoma (PB-DLBCL) is rare, with a high incidence of central nervous system (CNS) relapse. This study aims to investigate clinical characteristics, prognostic factors, and outcomes in Taiwanese PB-DLBCL patients and review the literature on PB-DLBCL. METHODS Thirty-one PB-DLBCL patients diagnosed between 2000 and 2021 were retrospectively enrolled for analysis. RESULTS The median age was 49 (range 26-79) years. The complete remission (CR) rate was 90.3%. Nine (90%) of the ten patients who experienced relapse had CNS involvement at the time of relapse. The one-year, two-year, and five-year progression-free survival (PFS) rates were 86.6% (95% confidence interval [CI] 75.2-99.8), 75.8% (95% CI 61.6-93.2), and 45.1% (95% CI 29.5-68.9), respectively. The five-year overall survival (OS) rate was 64.1% (95 % CI 48.4-85.0). A stage-modified International Prognostic Index (mIPI) less than two (five-year PFS rate 52.5% vs. 17.1%, P = 0.02) and the achievement of CR after first-line treatment (two-year PFS rate 80.3% vs. 33.3%, P < 0.001) were significant favorable prognostic factors for PFS. Hematopoietic stem cell transplantation (HSCT) after the first relapse was associated with significantly improved post-relapse OS (five-year OS rate 85.7% vs. 20.0%, P = 0.02) and PFS (five-year PFS rate 85.7% vs. 20.0%, P = 0.02). CONCLUSION Patients with low-risk mIPI scores, CR after first-line treatment, and those who underwent HSCT after the first relapse had significantly better survival. Intrathecal chemotherapy conferred no benefit in preventing CNS relapse. Further research is needed to assess frontline HSCT's effectiveness in improving outcomes and preventing CNS relapses in PB-DLBCL patients.

However, the value of hypofractionated RT in this setting has not been confirmed. METHODS We retrospectively analyzed patients with R/R aggressive B-cell lymphoma who received hypofractionated RT between January 2020 and August 2022 at a single institution. The objective response rate (ORR), overall survival (OS), progression-free survival (PFS) and acute side effects were analyzed. RESULTS A total of 30 patients were included. The median dose for residual disease was 36 Gy, at a dose per fraction of 2.3-5 Gy. After RT, the ORR and complete response (CR) rates were 90% and 80%, respectively. With a median follow-up of 10 months (range, 2-27 months), 10 patients (33.3%) experienced disease progression and three died. The 1-year OS and PFS rates for all patients were 81.8% and 66.3%, respectively. The majority (8/10) of post-RT progressions involved out-of-field relapses. Patients with relapsed diseases, no response to systemic therapy, multiple lesions at the time of RT, and no response to RT were associated with out-of-field relapses. PFS was associated with response to RT (P = 0.001) and numbers of residual sites (P < 0.001). No serious non-hematological adverse effects (≥ grade 3) associated with RT were reported. CONCLUSION These data suggest that hypofractionated RT was effective and tolerable for patients with R/R aggressive B-cell lymphoma, especially for those that exhibited localized residual disease.

Decreased lymphoma-related deaths and improved long-term relative survival with radiotherapy for early-stage diffuse large B-cell lymphoma in the rituximab era. Radiother Oncol 2023; 188:109902. [PMID: 37678622 DOI: 10.1016/j.radonc.2023.109902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 08/30/2023] [Accepted: 08/31/2023] [Indexed: 09/09/2023]
Abstract
BACKGROUND We aimed to investigate the incidence of lymphoma-related death (LRD) and the long-term net survival benefit of radiotherapy (RT) for early-stage diffuse large B-cell lymphoma (DLBCL) in the rituximab era. METHODS 10,841 adults diagnosed with early-stage DLBCL between 2002-2015 were retrospectively analyzed using data from the Surveillance, Epidemiology, and End Results database. Primary therapy was categorized into combined-modality treatment (CMT, n = 3,631) and chemotherapy alone (n = 7,210). Competing risk analysis was used to evaluate the cumulative incidence of mortality. Inverse probability of treatment weighting (IPTW) was used to balance groups. The net survival benefit of RT was estimated through relative survival (RS), standardized mortality ratio (SMR), and transformed Cox regression, while controlling for background mortality. RESULTS Patients initially treated with CMT had a lower cumulative incidence of LRD compared to those who received chemotherapy alone (HR 0.63, 95%CI: 0.57-0.69; P < 0.001). The 10-year overall survival (OS), RS, and SMR for CMT were 66.1%, 85.0%, and 1.71 respectively, which were significantly better than those for chemotherapy alone (53.0%; 69.8%; 2.62; all P < 0.001). IPTW and multivariable analysis revealed that the addition of RT led to better OS (HR 0.67, 95%CI: 0.62-0.71; P < 0.001) and RS (HR 0.69, 95%CI: 0.65-0.74; P < 0.001). Moreover, compared with chemotherapy alone, the benefit of OS and RS for CMT increased over time within 10 years of diagnosis. CONCLUSION RT reduced LRD and improved the long-term net survival in early-stage DLBCL in the rituximab era. Further prospective studies are warranted to assess the specific patient population that would benefit the most from consolidative RT in early-stage DLBCL.

Abstract
Hexokinase 2 (HK2) has been associated with carcinogenic growth in numerous kinds of malignancies as essential regulators during the processing of glucose. This study aimed to explore the effects of HK2 on diffuse large B-cell lymphoma (DLBCL) cells via the ERK1/2 signaling. Expressions of HK2 and ERK1/2 were examined in DLBCL cell lines using quantitative reverse transcription polymerase chain reaction and western blotting. HK2 and ERK1/2 were attenuated through HK2 small-interfering RNA (siRNA) and ERK inhibitor FR180204, respectively, in U2932 and SU-DHL-4 cells. Cell Counting Kit-8, clone formation, transwell, and flow cytometry assays were used in evaluating the effects of HK2 and ERK1/2 on cell proliferation, migration, and apoptosis. Moreover, a xenograft model was created to assess the roles of HK2 in vivo. HK2 and ERK1/2 were evidently up-regulated in DLBCL cell lines. HK2 knockdown and FR180204 markedly suppressed the proliferation and clonogenesis of U2932 and SU-DHL-4 cells and promoted cell apoptosis in vitro. We also found that HK2 silencing suppressed tumor growth in vivo. Notably, HK2 knockdown inactivated the ERK1/2 signaling pathway both in vitro and in vivo. These data indicate that inhibition of HK2 may suppress the proliferation, migration, and invasion of DLBCL cells, partly via inhibiting the ERK1/2 signaling pathway.

Abstract
BACKGROUND Primary intramedullary spinal cord lymphoma (PISCL) is rare and easily misdiagnosed with the lack of typical clinical features and non-specific imaging manifestations. CASE PRESENTATION A 49-year-old man was admitted to our hospital because of persistent limbs numbness, pinprick-like pain in the posterior neck and unsteady gaits. He has brisk tendon reflexes and positive Babinski's sign. Magnetic resonance imaging (MRI) of the cervical spine showed an abnormal signal with aberrant reinforcement at medulla oblongata and the level of C1-C7. He was clinically diagnosed as longitudinally extensive transverse myelitis (antibody-negative). Steroid pulse therapy was administered and resulted in reduced symptoms. One month later, his situation was exacerbated compared to the onset. We launched a new cascade of steroid pulse therapy. But it did not improve his symptoms. Finally, the biopsy pathology confirmed PISCL. Chemotherapy, radiotherapy and zanubrutinib were administered and until now about 3 years into treatment the patient is still survival. CONCLUSIONS Based on our case and literature review, we recommend that spinal onset patients react ineffectively to standard immunoglobulins or hormonal treatments or experience a relapse after a short time relief should take PISCL into consideration.

Abstract
Diffuse large B-cell lymphoma (DLBCL) represents the commonest subtype of non-Hodgkin lymphoma and encompasses a group of diverse disease entities, each harboring unique molecular and clinico-pathological features. The understanding of the molecular landscape of DLBCL has improved significantly over the past decade, highlighting unique genomic subtypes with implications on targeted therapy. At the same time, several new treatment modalities have been recently approved both in the frontline and relapsed settings, ending a dearth of negative clinical trials that plagued the past decade. Despite that, in the real-world setting, issues like drug accessibility, reimbursement policies, physician and patient preference, as well as questions regarding optimal sequencing of treatment options present difficulties and challenges in day-to-day oncology practice. Here, we review the recent advances in the therapeutic armamentarium of DLBCL and discuss implications on the practice landscape, with a particular emphasis on the context of the healthcare system in Singapore.

Zinc oxide nanoparticles induce toxicity in diffuse large B-cell lymphoma cell line U2932 via activating PINK1/Parkin-mediated mitophagy. Biomed Pharmacother 2023; 164:114988.

Abstract
Diffuse large B-cell lymphoma (DLBCL) is the most common type of lymphoma. Zinc oxide (ZnO) nanoparticles have excellent anti-tumor properties in the biomedical field. The present study aimed to explore the underlying mechanism by which ZnO nanoparticles induce toxicity in DLBCL cells (U2932) via the PINK1/Parkin-mediated mitophagy pathway. After U2932 cells were exposed to various concentrations of ZnO nanoparticles, the cell survival rate, reactive oxygen species (ROS) generation, cell cycle arrest, and changes in the expression of PINK1, Parkin, P62, and LC3 were monitored. Moreover, we investigated monodansylcadaverine (MDC) fluorescence intensity and autophagosome and further validated the results using the autophagy inhibitor 3-methyladenine (3-MA). The results showed that ZnO nanoparticles could effectively inhibit the proliferation of U2932 cells and induce cell cycle arrest at the G0/G1 phases. Moreover, ZnO nanoparticles significantly increased ROS production, MDC fluorescence intensity, autophagosome formation, and the expression of PINK1, Parkin, and LC3, and decreased the expression of P62 in U2932 cells. In contrast, the autophagy level was reduced after the intervention of the 3-MA. Overall, ZnO nanoparticles can trigger PINK1/Parkin-mediated mitophagy signaling in U2932 cells, which may be a potential therapeutic approach for DLBCL.

Abstract
Non-Hodgkin lymphomas represents a heterogeneous group of lymphoproliferative disorders characterized by different clinical courses, varying from indolent to highly aggressive. 18F-FDG-PET/CT is the current state-of-the-art diagnostic imaging, for the staging, restaging and evaluation of response to treatment in lymphomas with avidity for 18F-FDG, despite it is not routinely recommended for surveillance. PET-based response criteria (using five-point Deauville Score) are nowadays uniformly applied in FDG-avid lymphomas. In this review, a comprehensive overview of the role of 18F-FDG-PET in Non-Hodgkin lymphomas is provided, at each relevant point of patient management, particularly focusing on recent advances on diffuse large B-cell lymphoma and follicular lymphoma, with brief updates also on other histotypes (such as marginal zone, mantle cell, primary mediastinal- B cell lymphoma and T cell lymphoma). PET-derived semiquantitative factors useful for patient stratification and prognostication and emerging radiomics research are also presented.

Cancer Med 2023. [PMID: 37081761 DOI: 10.1002/cam4.5957] [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: 01/28/2023] [Revised: 03/25/2023] [Accepted: 04/01/2023] [Indexed: 04/22/2023] Open
Abstract
BACKGROUND Optimization of risk stratification is important for facilitating prognoses and therapeutic decisions regarding diffuse large B-cell lymphoma (DLBCL). However, a simple and applicable prognostic tool is lacking for individuals with human immunodeficiency virus (HIV)-related DLBCL in the era of combined antiretroviral therapy (cART). METHODS This retrospective multicenter observational study included 147 HIV-related DLBCL patients with histologically confirmed DLBCL from 2013 to 2020. The total group was divided into training (n = 78) and validation (n = 69) cohorts to derive the best prognostic score. Clinicopathological and characteristic biomarkers correlated with clinical outcomes were analyzed. RESULTS Age, Ann Arbor stage, lactate dehydrogenase (LDH) ratio, bulky disease, and red blood cell distribution width (RDW) ratio retained robust independent correlations with overall survival (OS) in multivariate analysis. A new and practical prognostic model was generated and externally validated, classifying patients into three categories with significantly different survival rates. Moreover, the new index outperformed the International Prognostic Index (IPI) score (area under the curve values of 0.94 vs. 0.81 in the training cohort and 0.85 vs. 0.74 in the validation cohort, C-indices of 0.80 vs. 0.70 in the training cohort and 0.74 vs. 0.70 in the validation cohort, and integrated discrimination improvement values of 0.203 in the training cohort and 0.175 in the validation cohort) and was better at defining intermediate- and high-risk groups. The calibration curves performed satisfactorily for predicting 3-year OS in the training and validation cohorts. CONCLUSIONS We developed and validated a simple and feasible prognostic model for patients with HIV-related DLBCL that had more discriminative and predictive accuracy than the IPI score for risk stratification and individualized treatment in the cART era.

Abstract
Previous studies have identified several ICAM3 transcript variants and mainly investigated the function of the longest transcript of ICAM3 in various tumor progressions. However, the role of the other ICAM3 transcript variants remains unclear. Herein, we detected the expression of ICAM3 transcript variants 1-4 in DLBCL cells and tumor tissues, disclosed that variants 1, 3, and 4 were expressed in normal B cell lines and 3 DLBCL cell lines except SU-DHL-2 as well as tumor tissues, while variant 2 was not detected. Moreover, we found that ectopic expression of variants 1-4 enhanced cell proliferation by accelerating the cell cycle in SU-DHL2 cells in vitro. In addition, variants 1-4 overexpression showed no effects on SU-DHL2 cell apoptosis. Interestingly, the expression of variants 1, 3, and 4 promoted cell migration and EMT process while variant 2 had no effects. Collectively, the above results displayed the different roles of ICAM3 transcript variants in mediating DLBCL progression.

Abstract
Wilms' tumor 1-associating protein (WTAP) is required for N6-methyladenosine (m6A) RNA methylation modifications, which regulate biological processes such as RNA splicing, cell proliferation, cell cycle, and embryonic development. m6A is the predominant form of mRNA modification in eukaryotes. WTAP exerts m6A modification by binding to methyltransferase-like 3 (METTL3) in the nucleus to form the METTL3-methyltransferase-like 14 (METTL14)-WTAP (MMW) complex, a core component of the methyltransferase complex (MTC), and localizing to the nuclear patches. Studies have demonstrated that WTAP plays a critical role in various cancers, both dependent and independent of its role in m6A modification of methyltransferases. Here, we describe the recent findings on the structural features of WTAP, the mechanisms by which WTAP regulates the biological functions, and the molecular mechanisms of its functions in various cancers. By summarizing the latest WTAP research, we expect to provide new directions and insights for oncology research and discover new targets for cancer treatment.

Eur Radiol 2022; 33:77-88. [PMID: 36029345 DOI: 10.1007/s00330-022-09031-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 05/30/2022] [Accepted: 07/13/2022] [Indexed: 11/28/2022]
Abstract
OBJECTIVES The prediction of primary treatment failure (PTF) is necessary for patients with diffuse large B-cell lymphoma (DLBCL) since it serves as a prominent means for improving front-line outcomes. Using interim 18F-fluoro-2-deoxyglucose ([18F]FDG) positron emission tomography/computed tomography (PET/CT) imaging data, we aimed to construct multimodal deep learning (MDL) models to predict possible PTF in low-risk DLBCL. METHODS Initially, 205 DLBCL patients undergoing interim [18F]FDG PET/CT scans and the front-line standard of care were included in the primary dataset for model development. Then, 44 other patients were included in the external dataset for generalization evaluation. Based on the powerful backbone of the Conv-LSTM network, we incorporated five different multimodal fusion strategies (pixel intermixing, separate channel, separate branch, quantitative weighting, and hybrid learning) to make full use of PET/CT features and built five corresponding MDL models. Moreover, we found the best model, that is, the hybrid learning model, and optimized it by integrating the contrastive training objective to further improve its prediction performance. RESULTS The final model with contrastive objective optimization, named the contrastive hybrid learning model, performed best, with an accuracy of 91.22% and an area under the receiver operating characteristic curve (AUC) of 0.926, in the primary dataset. In the external dataset, its accuracy and AUC remained at 88.64% and 0.925, respectively, indicating its good generalization ability. CONCLUSIONS The proposed model achieved good performance, validated the predictive value of interim PET/CT, and holds promise for directing individualized clinical treatment. KEY POINTS • The proposed multimodal models achieved accurate prediction of primary treatment failure in DLBCL patients. • Using an appropriate feature-level fusion strategy can make the same class close to each other regardless of the modal heterogeneity of the data source domain and positively impact the prediction performance. • Deep learning validated the predictive value of interim PET/CT in a way that exceeded human capabilities.

Abstract
Diffuse large B-cell lymphoma and follicular lymphoma are the most commonly encountered non-Hodgkin lymphomas in clinical practice. Both are biologically heterogeneous, with management strategies that are becoming increasingly complex. Diffuse large B-cell lymphoma typically exhibits aggressive behavior but can be cured in the majority of cases with immunochemotherapy. While R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) has been the standard of care for decades, the recent combination of polatuzumab-vedotin-R-CHP (rituximab plus cyclophosphamide, doxorubicin, and prednisone) has demonstrated improved progression-free survival for patients with intermediate- and intermediate-high-risk disease. Numerous novel therapies, including targeted agents and immunotherapy-based approaches, have recently been approved for relapsed/refractory disease and have led to improved outcomes. Follicular lymphoma is an indolent lymphoma that remains incurable with standard approaches. Overall survival in most patients is excellent, although a proportion of patients will have early relapsing disease and poorer outcomes. The availability of novel agents in the relapsed/refractory setting has shifted the treatment algorithm, which requires thoughtful consideration of sequencing. This article will review recent developments in the treatment of diffuse large B-cell lymphoma and relapsed/refractory follicular lymphoma.
