Background: Interstitial pneumonitis (IP), a fatal complication of DLBCL treatment, can bring great challenges to clinicians. We retrospectively investigated clinical characteristics and risk factors of previous IP patients, and analyzed their survival data.
Methods: 556 DLBCL patients receiving CHOP-like regimens were enrolled between 2013 and 2018 in Sichuan Cancer Hospital.
Findings: The IP incidences were 4.9 % (27/556), 1.1 % (2/186), 5.2 % (10/191) and 8.4 % (15/179) in CHOP, R-CHOP and R-CDOP groups respectively (P = 0.005). When IP was diagnosed, monocyte and IL-6 were significantly higher while CD4 and CD4/CD8 significantly lower compared to baseline. 81.5 % (22/27) of IP patients were pathogen-negative with good response to glucocorticoid monotherapy. Only one patient died while the others recovered from IP and subsequently underwent previous chemotherapy. 19.2 % (5/26) of IP patients experienced IP recurrence, likely due to the reason of lower initial dose or faster withdrawal speed of glucocorticoid. Multivariate analysis identified male, in addition to G-CSF, rituximab and pegylated liposomal doxorubicin as risk factors. The 3-year PFS and OS were 74.1 % and 46.9 % respectively for patients with IP.
Interpretation: We suggest that IL-6, monocyte and CD4 should be monitored closely, especially in R-CHOP/R-CDOP group. Sufficient initial dose and slow decrease of glucocorticoid based on radiographic remissions were critical strategies to reduce IP recurrence. We speculate that drug-induced immune imbalance could be trigger of developing IP, causing a lower intensity cytokine storm, resulting in a potential immunotherapy. This complication might bring benefit in patients' survival through a mechanism similar to PD-1.

Objectives: To analyze the CT imaging features of extranodal natural killer/T (NK/T)-cell lymphoma, nasal type (ENKTCL-NT) involving the gastrointestinal tract (GI), and to compare them with those of Crohn's disease (CD) and diffuse large B-cell lymphoma (DLBCL).
Materials And Methods: Data were retrospectively collected from 17 patients diagnosed with GI ENKTCL-NT, 68 patients with CD, and 47 patients with DLBCL. The CT findings of ENKTCL-NT were analyzed and compared with those of CD and DLBCL.

Background: Whole-body magnetic resonance imaging (wbMRI) allows general assessment of systemic cancers including lymphomas without radiation burden.
Aim: To evaluate the diagnostic performance of wbMRI in the staging of diffuse large B-cell lymphoma (DLBCL), determine the value of individual MRI sequences, and assess patients' concerns with wbMRI.
Methods: In this single-center prospective study, adult patients newly diagnosed with systemic DLBCL underwent wbMRI on a 3T scanner [diffusion weighted images with background suppression (DWIBS), T2, short tau inversion recovery (STIR), contrast-enhanced T1] and fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) (reference standard).
Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma, and a sizable fraction of the DLBCL patients presents with advanced, relapsed, and refractory disease, demonstrating poor response to standard chemotherapy regimens. Radioimmunotherapy (RIT) has shown to be clinically effective in refractory DLBCL. We present the case of a patient with DLBCL with [18F]FDG-avid widespread skeletal as well as splenic involvement as poor prognostic extranodal disease on FDG PET/CT.

Background: Dexrazoxane has been studied for its ability to prevent anthracycline-induced cardiac dysfunction (AICD) in several trials but its use in clinical practice remains limited. This is related to the low to moderate quality of the generated evidence, safety concerns and restricted prescribing indications. Additional randomized trials are needed before this drug can be routinely integrated into cardio-oncology clinical practice.
View Article and Find Full Text PDFDiffuse large B-cell lymphoma (DLBCL) is a highly heterogeneous metastatic lymphoma that can be treated by targeting angiogenesis. Apolipoprotein C1 (APOC1) plays a significant role in the proliferation and metastasis of various malignant tumors; however, its role in DLBCL-particularly its effects on angiogenesis-remains largely unexplored. This study investigates the correlation between APOC1 expression and patient prognosis in DLBCL.
