Abstract Background: The primary cause of treatment failure in patients with refractory or relapsed B-cell non-Hodgkin lymphoma (r/r B-NHL) is resistance to current therapies, and therapy-induced senescence (TIS) stands out as a crucial mechanism contributing to tumor drug resistance. Here, we analyzed SENEX/Rho GTPase Activating Protein 18 (ARHGAP18) expression and prognostic significance in doxorubicin-induced B-NHL-TIS model and r/r B-NHL patients, investigating its target in B-NHL cell senescence and the effect of combining specific inhibitors on apoptosis resistance in B-NHL-TIS cells. Methods: Raji cells were transfected with the human SENEX shRNA recombinant lentiviral vector (Sh-SENEX) and the empty vector negative (NC) to… More >

Abstract Background: Dihydroartemisinin (DHA) is reported to be a potential anticancer agent, and the mechanisms underlying the effects of DHA on diffuse large B cell lymphoma however are still obscure. This study aimed to assess the antitumor effect of DHA on diffuse large B cell lymphoma cells and to determine the potential underlying mechanisms of DHA-induced cell apoptosis. Methods: Here, the Cell Counting Kit 8 assay was conducted to study cell proliferation. We performed Annexin V-FITC/propidium iodide staining, real-time polymerase chain reaction, and western blot analysis to analyze cell apoptosis and potential molecular mechanisms. Results: The results showed that DHA substantially… More >

Abstract Background: Intracranial lymphoma remains a challenging differential diagnosis in daily neurosurgical practice. We analyzed our early experience with a surgical series of frameless neuronavigated biopsies in Primary CNS Lymphomas (PCNSLs), highlighting the importance of using an intraoperative combined imaging protocol (5-ALA fluorescence, i-CT and ¹¹C-MET-PET) to overcome potential targeting errors secondary to tumor volume reduction after corticosteroid therapy. Materials and Methods: All patients treated for PCNLSs at our center in a 24-month period (1/1/2019 to 31/12/2020) were analyzed. Our cohort included 6 patients (4 males), with a median age of 67 years (59–82). A total of 45 samples were evaluated… More >

Abstract Chemotherapy-induced peripheral neuropathy (CIPN) frequently occurs in lymphoma patients receiving R-CHOP, a drug combination therapy. Although severe CIPN may lead to reduction and/or discontinuation of the medication, predictive factors of CIPN have not been investigated sufficiently to date. We performed a retrospective exploratory research to determine associations between prevalence of severe CIPN and sociodemographic data, health characteristics, and medical conditions such as anemia at initial diagnosis. Forty patients (indolent lymphoma, n=9; diffuse large B-cell lymphoma; n=31) received R-CHOP therapy from September 2009 to July 2014. The median age of patients was 58 years (range=27–76 years). Statistical analyses were applied to… More >

Abstract Despite therapeutic advances, the effective treatment for relapsed or refractory diffuse large B-cell lymphoma (DLBCL) remains a major clinical challenge. Evasion of apoptosis through upregulating antiapoptotic B-cell lymphoma-2 (BCL-2) family members and p53 inactivation, and abnormal activation of B-cell receptor signaling pathway are two important pathogenic factors for DLBCL. In this study, our aim is to explore a rational combination of BCL-2 inhibitor plus Bruton’s tyrosine kinase (BTK) blockade or p53 activation for treating DLBCL with the above characteristics. We demonstrated that a novel BCL-2 selective inhibitor APG-2575 effectively suppressed DLBCL with BCL-2 high expression via activating the mitochondrial apoptosis… More >

Abstract There have been great advances in the therapy of cancer and leukemia. However, there are still many neoplastic diseases that are difficult to treat. For example, it is often difficult to find effective therapies for aggressive cancer and leukemia. An NF- B inhibitor named dehydroxymethylepoxyquinomicin (DHMEQ) was discovered in 2000. This compound was designed based on the structure of epoxyquinomicin isolated from a microorganism. It was shown to be a specific inhibitor that directly binds to and inactivates NF- B components. Until now, DHMEQ has been used by many scientists in the world to suppress animal models of cancer and… More >

Abstract Hairy cell leukemia (LT) accounts for 2% of all leukemias. The diagnosis is based on the presence in the blood and/ or the marrow of hairy cells expressing CD103, CD123, CD11c and CD25. The BRAF^V600E mutation, a molecular marker of the disease, is present in more than 80% of cases. LT should be distinguished from other chronic B-cell lymphoproliferative disorders, including the variant form of hairy cell leukemia (HCL-V) and diffuse splenic red pulp lymphoma (DSRPL). Progress has recently been made in the management of patients. The purine analogues (PNAs) in monotherapy, deoxycoformycin (DCF) or 2-chloro-deoxyadenosine (CDA), remain the first-line… More >

Abstract Current cancer diagnosis procedure requires expert knowledge and is time-consuming, which raises the need to build an accurate diagnosis support system for lymphoma identification and classification. Many studies have shown promising results using Machine Learning and, recently, Deep Learning to detect malignancy in cancer cells. However, the diversity and complexity of the morphological structure of lymphoma make it a challenging classification problem. In literature, many attempts were made to classify up to four simple types of lymphoma. This paper presents an approach using a reliable model capable of diagnosing seven different categories of rare and aggressive lymphoma. These Lymphoma types… More >

Abstract Objective: The purpose was to explore the value of multi-slice spiral CT (MSCT) multiplanar reconstruction technique in the diagnosis and clinicopathological analysis of gastrointestinal lymphoma (GIL). Methods: 82 GIL patients treated in our hospital from February 2018 to February 2019 were selected as the experimental group of this study, and 82 patients with other gastrointestinal tumors diagnosed by pathology during the same period were selected as the control group. Both groups of patients were scanned by MSCT and analyzed by multiplanar reconstruction technique to compare the diagnostic results and clinicopathological indexes of the two groups. Results: The diagnostic accuracy of… More >

Abstract The present study aimed to clarify the role of SENEX in malignant cell proliferation in diffuse large B-cell lymphoma (DLBCL). 22 DLBCL patients (6 newly diagnosed cases, 7 cases at complete remission, and 9 relapsed cases) were included in the study. Our results indicated that both SENEX gene and protein were significantly increased in peripheral blood mononuclear cells (PBMCs) and tumor cells of relapsed DLBCL patients, accompanied by overexpression of p21, p16, and phosphorylated retinoblastoma (Rb). Silencing the SENEX gene in a DLBCL cell line caused a significant decrease in cell proliferation and inhibited cell cycle progression in the G1… More >
