CD5MYC predicts worse prognosis in diffuse large B-cell lymphoma.

The dual expression of CD5 and MYC protein (DECM) on B-lymphocytes may arise at a specific stage of de novo diffuse large B-cell lymphoma (DLBCL). This study retrospectively reviewed 210 patients with de novo DLBCL at the Affiliated Hospital of Jiangnan University between 2006 and 2017. DECM was significantly correlated with a worse prognosis than that in either the CD5 or MYC or CD5MYC patients.

Prognostic significance of serum aspartic transaminase in diffuse large B-cell lymphoma.

Background: Liver function is routinely assessed in clinical practice as liver function tests provide sensitive indicators of hepatocellular injury. However, the prognostic value of enzymes that indicate hepatic injury has never been systematically investigated in lymphoma, including diffuse large B-cell lymphoma (DLBCL).

Methods: This study examined the prognostic value of baseline aspartic transaminase (AST) in DLBCL patients.

Inflammation marker ESR is effective in predicting outcome of diffuse large B-cell lymphoma.

Background: Systemic inflammation has been implicated in cancer development and progression. This study examined the best cutoff value of erythrocyte sedimentation rate (ESR) in diffuse large B-cell lymphoma (DLBCL) patients.

Methods: The relationship between ESR and clinical characteristics was analyzed in 182 DLBCL patients from 2006 to 2017.

CD30 expression and its correlation with MYC and BCL2 in de novo diffuse large B-cell lymphoma.

Aim: CD30+ diffuse large B-cell lymphoma (DLBCL) has emerged as a new immunophenotypic variant of DLBCLs. However, the prevalence of CD30 positivity is variable according to different studies, and the prognostic significance of CD30 is also controversial. This study aimed to investigate the positive expression rate and prognostic impact of CD30 in DLBCLs and try to find the correlated influences.

Increasing circulating exosomes-carrying TRPC5 predicts chemoresistance in metastatic breast cancer patients.

Chemoresistance, the major obstacle in breast cancer chemotherapy, results in unnecessary chemotherapy and wasting of medical resources. No feasible method has been available to predict chemoresistance before chemotherapy. In our previous study, elevated expression of transient receptor potential channel TRPC5 was found to be an essential element for chemoresistance in breast cancer cells, and it was determined that it could be transferred to chemosensitive breast cancer cells through releasing extracellular vesicles (EV) containing TRPC5 from chemoresistant cells, resulting in acquired chemoresistance.

Elevated expression of TrpC5 and GLUT1 is associated with chemoresistance in colorectal cancer.

Reprogramming of energy metabolism (aerobic glycolysis) is thought to play an essential role in cancer. Compared to oxidative phosphorylation, aerobic glycolysis consumes more glucose through the upregulation of glucose transporters, notably glucose transporter 1 (GLUT1). Elevated glycolysis occurs in chemoresistant cancer cells, but the detailed mechanism is not well understood.

Prevalence and clinicopathologic features of CD30-positive de novo diffuse large B-cell lymphoma in Chinese patients: a retrospective study of 232 cases.

Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease that great efforts had been made in to build up molecular and immunophenotypic subgroups that could relatively accurate indicate prognosis and give clue to therapy. Recently, CD30 was reported as a useful predictor with favorable clinical outcome. However, CD30 expression patterns and the clinicopathologic features of CD30 positive DLBCL are not well described thus far, especially in Asian patients.

The distinct clinical features and prognosis of the CD10⁺MUM1⁺ and CD10⁻Bcl6⁻MUM1⁻ diffuse large B-cell lymphoma.

Using an immunohistochemistry (IHC) based method, diffuse large B-cell lymphoma (DLBCL) can be classified into germinal center B-cell (GCB) and non-GCB subtypes. However, the prognostic value of Hans algorithm was contradictory in the literature. Using IHC and fluorescence in situ hybridization, we analyzed the antibodies applied in Hans algorithm and other genetic factors in 601 DLBCL patients and prognostic value of Hans algorithm in 306 cases who were treated with chemoimmunotherapy.

Association between polymorphism of CD20 gene and chronic lymphocytic leukemia in Chinese population.

Rituximab was widely used in clinical practice. Some chronic lymphocytic leukemia (CLL) patients were primary or secondary resistance to rituximab, but the mechanism has not been yet clear. CD20 gene coding region was amplified by PCR in 92 cases of newly diagnosed CLL patients and 200 healthy donors.

TP53 dysfunction in diffuse large B-cell lymphoma.

The aberrations of TP53 gene and dysregulation of the TP53 pathway are important in the pathogenesis of many human cancers, including malignant lymphomas, especially for diffuse large B cell lymphoma (DLBCL). By regulating many downstream target genes or molecules, TP53 governs major defenses against tumor growth and promotes cellular DNA repair, apoptosis, autophagy, cell cycle arrest, signaling, transcription, immune or inflammatory responses and metabolism. Dysfunction of TP53, including microRNA regulations, copy number alterations of TP53 pathway and TP53 itself, dysregulation of TP53 regulators, and somatic mutations by abnormal TP53 function modes, play an important role in lymphoma generation, progression and invasion.

Epstein-Barr virus positive diffuse large B-cell lymphoma predict poor outcome, regardless of the age.

Epstein-Barr virus (EBV) positive diffuse large B-cell lymphoma (DLBCL) of the elderly is defined as patients older than 50 years alone. However, recent studies showed young patients with sound immune status could also be affected. In this study, we investigated the clinical features and outcomes of patients with EBV positive DLBCL in the different age groups using different EBER cut-off values.

MYC or BCL2 copy number aberration is a strong predictor of outcome in patients with diffuse large B-cell lymphoma.

Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma (NHL). Patients with DLBCL harboring MYC aberrations concurrent with BCL2 or/and BCL6 aberrations constitute a specific group with extremely poor outcome. In this study, we retrospectively investigated the incidence and prognosis of MYC, BCL2, and BCL6 aberrations with DLBCL patients in Chinese population.

Immunohistochemical algorithm alone is not enough for predicting the outcome of patients with diffuse large B-cell lymphoma treated with R-CHOP.

Gene expression profiling (GEP), which can divide DLBCL into three groups, is impractical to perform routinely. Although algorithms based on immunohistochemistry (IHC) have been proposed as a surrogate for GEP analysis, the power of them has diminished since rituximab added to the chemotherapy. We assessed the prognostic value of four conventional algorithms and the genes in each and out of algorithm by IHC and fluorescence in situ hybridization in DLBCL patients receiving immunochemotherapy.

TP53 Pro72 allele potentially increases the poor prognostic significance of TP53 mutation in chronic lymphocytic leukemia.

Previous studies have investigated the associations between TP53 mutations and codon 72 polymorphisms and prognosis in chronic lymphocytic leukemia (CLL). However, the joint effect of TP53 mutations and TP53 codon 72 polymorphisms on CLL prognosis remains uncertain. We used direct sequencing to detect TP53 mutations and codon 72 genotype in 207 patients with CLL.

Polyclonal antibody targeting SOX11 cannot differentiate mantle cell lymphoma from B-cell non-Hodgkin lymphomas.

Objectives: To determine whether SOX11 is a diagnostic marker of mantle cell lymphoma (MCL).

Methods: We analyzed SOX11 expression in 349 B-cell non-Hodgkin lymphomas (B-NHLs) via immunohistochemistry.

Results: Nuclear staining of SOX11 was observed in 54 (93.

The role of SOX11 in mantle cell lymphoma.

The mechanism of SOX11 function has been widely published recently mainly focused on histone modifications. Besides diagnostic value in mantle cell lymphoma (MCL), SOX11 has also prognostic significance. Although it can also be observed in a fraction of other T and B-cell lymphomas, a monoclonal antibody, called SOX11-C1, may improve the function of SOX11 in both diagnosis and prognosis evaluation.
