Three-year Follow-up on the Safety and Effectiveness of Rituximab Plus Chemotherapy as First-Line Treatment of Diffuse Large B-Cell Lymphoma and Follicular Lymphoma in Real-World Clinical Settings in China: A Prospective, Multicenter, Noninterventional Study / 中华医学杂志(英文版)

Background@#Prospective real-life data on the safety and effectiveness of rituximab in Chinese patients with diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL) are limited. This real-world study aimed to evaluate long-term safety and effectiveness outcomes of rituximab plus chemotherapy (R-chemo) as first-line treatment in Chinese patients with DLBCL or FL. Hepatitis B virus (HBV) reactivation management was also investigated.@*Methods@#A prospective, multicenter, single-arm, noninterventional study of previously untreated CD20-positive DLBCL or FL patients receiving first-line R-chemo treatment at 24 centers in China was conducted between January 17, 2011 and October 31, 2016. Enrolled patients underwent safety and effectiveness assessments after the last rituximab dose and were followed up for 3 years. Effectiveness endpoints included progression-free survival (PFS) and overall survival (OS). Safety endpoints were adverse events (AEs), serious AEs, drug-related AEs, and AEs of special interest. We also reported data on the incidence of HBV reactivation.@*Results@#In total, 283 previously untreated CD20-positive DLBCL and 31 FL patients from 24 centers were enrolled. Three-year PFS was 59% (95% confidence interval [CI]: 50-67%) for DLBCL patients and 46% (95% CI: 20-69%) for FL patients. For DLBCL patients, multivariate analyses showed that PFS was not associated with international prognostic index, tumor maximum diameter, HBV infection status, or number of rituximab treatment cycles, and OS was only associated with age >60 years (P < 0.05). R-chemo was well tolerated. The incidence of HBV reactivation in hepatitis B surface antigen (HBsAg)-positive and HBsAg-negative/hepatitis B core antibody-positive patients was 13% (3/24) and 4% (3/69), respectively.@*Conclusions@#R-chemo is effective and safe in real-world clinical practice as first-line treatment for DLBCL and FL in China, and that HBV reactivation during R-chemo is manageable with preventive measures and treatment.@*Trial Registration@#ClinicalTrials.gov, NCT01340443; https://clinicaltrials.gov/ct2/show/NCT01340443.

Correlation of Gemin 3 SNP in the microRNA Biosynthesis Pathway with Risk and Prognosis of Patients with Non-Hodgkin's Lymphoma / 中国实验血液学杂志

<p><b>OBJECTIVE</b>To evaluate the correlation of single nucleotide polymorphisms (SNP) of Gemin 3(rs197412) in the miRNA biosynthesis with NHL cancer risk and overall prognosis.</p><p><b>METHODS</b>miR-SNP were genotyped using PCR-ligase detection reaction(LAR, LCR) in NHL group of 230 non-Hodgkin lymphoma (NHL) patients and in control group of 120 healthy persons. The survival curves were drawn using the Kaplan-Meier method, and comparisons between the curves were made using the log-rank test. Multivariate survival analysis was performed by using a Cox proportional hazards model.</p><p><b>RESULTS</b>The rs197412 genotype distribution difference was not statistically significant, in NHL and control group; the survival time of patients carrying the rs197412 TT genotype was significantly longer than that of the patients carrying the CC+CT genotype (P=0.007). In addition, rs197412 was independent from the survival of NHL patients by multivariate analysis (RR: 2.138,95% CI: 1.303-3.508, P<0.01).</p><p><b>CONCLUSION</b>The single nucleotide polymorphisms of Gemin 3 (rs197412) in the miRNA processing are not related with NHL risk, but that may affect NHL survival.</p>
