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.

Influence of co-stimulatory molecules B7-H4 expression on the prognosis of patients with gastric cancer treated with cytokine-induced killer cells adoptive immunotherapy / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the influence of co-stimulatory molecules B7-H4 expression on prognosis of gastric cancer patients treated by cytokine-induced killer cells (CIK cells) adoptive immunotherapy.</p><p><b>METHODS</b>Clinical data of 156 cases of gastric cancer patients were retrospectively analyzed. Patients were divided into chemotherapy group(n=81) and chemotherapy combined with CIK cell therapy group(n=75). B7-H4 expression was detected in the surgical specimens of gastric cancer patients by immunohistochemistry assay. Disease-free survival was compared between the chemotherapy group and the CIK group at different expression levels of B7-H4.</p><p><b>RESULTS</b>The difference was not statistically significant in all clinical and pathological data between the chemotherapy group and the CIK treatment group (P>0.05). The postoperative median tumor-free survival in two groups was 18.0 and 45.0 months, respectively, and the difference was statistically significant (chi(2)=11.631, P=0.001). The postoperative median survival time was 27.0 and 49.0 months, respectively, and the difference was statistically significant (chi(2)=10.907, P=0.001). In 86 patients with low B7-H4 expression, the median tumor-free survival time was 32.0 and 62.0 months, respectively, and the difference was statistically significant (chi(2)=4.663,P=0.03). In 70 patients with high B7-H4 expression, the median tumor-free survival time was 11.0 and 18.0 months, respectively, and the difference was statistically significant (chi(2)=11.971, P=0.001).</p><p><b>CONCLUSION</b>The median tumor-free survival time of patients with gastric cancer may be further improved by chemotherapy combined with CIK cell therapy, regardless of the level of B7-H4 expression.</p>

Expression and clinical significance of costimulatory molecule B7-H3 mRNA and B7-H3 protein in gastric carcinoma / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To study the expression of B7-H3 mRNA and B7-H3 protein in gastric carcinoma and their clinical significance.</p><p><b>METHODS</b>The expression of B7-H3 mRNA and B7-H3 protein in gastric carcinoma and the nearby normal tissue of 38 patients was detected by real-time RT-PCR and immunohistochemical assay respectively.</p><p><b>RESULTS</b>B7-H3 mRNA was expressed both in gastric carcinoma and nearby normal tissue, but the expression level in gastric carcinoma was much lower than that in nearby normal tissue. There were no significant differences of B7-H3 mRNA expression among gender, age, histological type, tumor size, lymph node metastasis and invasive depth (all P >0.05). The positive rate of B7-H3 protein expressed in gastric carcinoma was 39.5%. There were no significant differences of B7-H3 protein expression among gender, age, histological type, tumor size, lymph node metastasis and invasive depth (all P >0.05), but there were significant differences among groups of clinical stage (P=0.022) and pathological grade (P=0.039). Kaplan-Meier analysis revealed that disease-free survival or overall survival of the patients with positive B7-H3 expression were significantly longer than those with negative B7-H3 expression (P=0.009 and P=0.010 respectively).</p><p><b>CONCLUSION</b>Detection of B7-H3 expression in gastric carcinoma will be beneficial to the judgment of the prognosis of gastric carcinoma and the choice of individualized treatment.</p>

Lipids changes in liver cancer / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Liver is one of the most important organs in energy metabolism. Most plasma apolipoproteins and endogenous lipids and lipoproteins are synthesized in the liver. It depends on the integrity of liver cellular function, which ensures homeostasis of lipid and lipoprotein metabolism. When liver cancer occurs, these processes are impaired and the plasma lipid and lipoprotein patterns may be changed. Liver cancer is the fifth common malignant tumor worldwide, and is closely related to the infections of hepatitis B virus (HBV) and hepatitis C virus (HCV). HBV and HCV infections are quite common in China and other Southeast Asian countries. In addition, liver cancer is often followed by a procession of chronic hepatitis or cirrhosis, so that hepatic function is damaged obviously on these bases, which may significantly influence lipid and lipoprotein metabolism in vivo. In this review we summarize the clinical significance of lipid and lipoprotein metabolism under liver cancer.

Multicenter phase II study of modified FOLFIRI regimen in the advanced colorectal cancer patient refractory to fluoropyrimidine and oxaliplatin / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of modified FOLFIRI regimen in advanced colorectal cancer (CRC) patients refractory to fluoropyrimidine and oxaliplatin.</p><p><b>METHODS</b>The modified FOLFIRI regimen consisted of intravenous infusion of irinotecan 180 mg/m2 d1 + LV 200 mg/m2 dl + 5-Fu 400 mg/m2 bolus dl plus 46-hour intravenous infusion of 5-Fu 2.4 g/m2, every 2 weeks as one cycle.

The median time to progression was 96 days. Safety analysis was based on the data of 83 evaluable patients. The most frequently observed grade 3 or 4 toxicities were neutropenia (24.1%), nausea/vomiting (8.4%), and diarrhea (2.4%).</p><p><b>CONCLUSION</b>Modified FOLFIRI regimen is effective and well tolerated in patients with advanced colorectal cancer refractory to fluoropyrimidine and oxaliplatin.</p>
