Recommendations did not agree on the safety of using disease-modifying antirheumatic drugs in RA patients with cancer, except for the contraindication of tumor necrosis factor inhibitors in patients at risk for lymphoma.
While our understanding of the biology of CD30 in lymphoma continues to evolve, our need to detect and measure its expression at the protein level remains critically important for diagnosis and patient care.
Following a broad panel of immunohistochemical stains, the strong positive staining of the spindle cells for LCA (CD45), CD20, and Bcl-6 confirmed the diagnosis of follicle center cell lymphoma.
This was accompanied by a reduction of expression of the B lymphoma Moloney murine leukemia virus (Mo-MLV) insertion region 1 (Bmi1) at both gene and protein levels.
Following a broad panel of immunohistochemical stains, the strong positive staining of the spindle cells for LCA (CD45), CD20, and Bcl-6 confirmed the diagnosis of follicle center cell lymphoma.
Both patients were diagnosed with NMOSD and initiated on anti-CD20 agents prior to lymphoma diagnosis, though the short duration of exposure argues against a direct role.
The gross appearance of the capsules as well as the presence, extent and depth of tumor cells on the luminal side and number of sections involved by lymphoma were determined by review of routine stains and CD30 immunohistochemistry.
Both patients were diagnosed with NMOSD and initiated on anti-CD20 agents prior to lymphoma diagnosis, though the short duration of exposure argues against a direct role.
Patients with abdominal nodal disease had inferior lymphoma specific survival (p=0.04) and presented with higher age adjusted IPI (p<0.001), lactate dehydrogenase (p<0.001) and more often advanced stage (p<0.001), bulky disease (p<0.001), B-symptoms (p<0.001), and double expression of MYC and BCL2 (p=0.02) compared to patients without nodal abdominal involvement, but less often extranodal involvement (p<0.02).
This was a retrospective study of 238 patients, including 92 with type-2 DM (DM2) and 11 with type-1 DM (DM1), having routine whole body FDG PET/CT.Patients with lymphoma were excluded.
Comparisons of CT features and <sup>18</sup>F-FDG metabolic indices between benign and malignant entities, as well as among primary and secondary malignancies and lymphoma, were performed.

IL-6-induced STAT3 or STAT5 activation is a critical mechanism underlying PI3K inhibitor resistance in lymphoma, supporting the utility of IL-6 as an effective biomarker to predict therapeutic response to PI3K inhibitors.
For this, we determined the ABCB1 inhibiting properties of our compounds in a mouse T-lymphoma cell line model and then evaluated the drug-enhancing properties of selected compounds in a co-application with clofazimine in our Mtb strain.
We developed humanized, second-generation CAR T cells against another B cell-specific marker, B cell activating factor receptor (BAFF-R), which demonstrated cytotoxicity against human lymphoma and acute lymphoblastic leukemia (ALL) lines.
Here, we report that myeloid-deficient Becn1 (Becn1ΔM) mice developed neutrophilia, were hypersusceptible to LPS-induced septic shock, and had a high risk of developing spontaneous precursor B cell (pre-B cell) lymphoma with elevated expression of immunosuppressive molecules programmed death ligand 1 (PD-L1) and IL-10.

Adoptive cellular therapies using chimeric antigen receptor T (CAR-T) cells have achieved remarkable clinical responses in B cell leukemia and lymphoma but the effect on solid tumors including lung cancer is limited.
Cytokine release syndrome (CRS) remains to be a major adverse effect of chimeric antigen receptor T (CAR-T) cell therapy in B-cell acute lymphoblastic leukemia (B-ALL) and lymphoma.
New targeted therapies for hematological malignancy include chimeric antigen receptor T cells (CAR T cells), Bi-specific T-cell Engager (BiTE) blinatumomab, and the antibody-drug conjugate (ADC) of calicheamicin inotuzumab ozogamicin for acute lymphoblasic leukemia (ALL) and lymphoma; the Bruton's tyrosine kinase (BTK) inhibitor ibrutinib and phosphatidylinositol 3-kinase (PI3Kδ) inhibitor idelalisib for lymphoma and graft-versus-host disease (GVHD); FMS-like tyrosine kinase 3 (FLT3) inhibitors, such as midostaurin, sorafenib and gilteritinib for acute myeloid leukemia (AML); and the BCL-2 inhibitor venetoclax for a range of hematological malignancies including lymphoma and leukemia.
