Comparison of iron isomaltoside ferumoxytol with iron sucrose for iron deficiency anemia: a meta-analysis of randomized controlled trials.

Introduction: The efficacy of iron isomaltoside ferumoxytol versus iron sucrose to treat iron deficiency anemia remains controversial. We conduct this meta-analysis to explore the influence of iron isomaltoside ferumoxytol versus iron sucrose on iron deficiency anemia. Methods: We have searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through March 2021 for randomized controlled trials (RCTs) assessing the effect of iron isomaltoside ferumoxytol versus iron sucrose on iron deficiency anemia. Meta-analysis was performed using the random-effect model. Results: Four RCTs involving 3892 patients were included in the meta-analysis. Overall, compared with iron sucrose for iron deficiency anemia, iron isomaltoside showed similar change of Hb (SMD=0.14; 95% CI=-0.07 to 0.35; P=0.18), Hb responder (SMD=1.41; 95% CI=0.71 to 2.81; P=0.33), serum ferritin (SMD=15.13; 95% CI=-23.45 to 53.71; P=0.44), and transferrin saturation (SMD=1.20; 95% CI=-1.08 to 3.47; P=0.30). However, iron isomaltoside further improved serum-ferritin at week 2 than iron sucrose (SMD=204.79; 95% CI=38.23 to 371.35; P=0.02). Conclusions: Iron isomaltoside ferumoxytol showed comparable efficacy to iron sucrose for the treatment of iron deficiency anemia.

Comparisons of effects of SOX and mFOLFOX6 chemotherapy regimens on patients with locally advanced gastric cancer.

The neoadjuvant chemotherapy plays an important role in locally advanced gastric cancer, but its efficacy, safety profiles and clinical outcomes among different regimens still remain controversial. In this study, totally 231 eligible patients with locally advanced gastric cancer were enrolled. These patients were divided into the observation group (SOX regimen, n = 123) and control group (mFOLFOX6 regimen, n = 108) according to different chemotherapy regimens. Then, the differences in chemotherapy efficacy, adverse reactions, surgical characteristics, complications and survival condition were compared. No significant differences were observed in clinical efficacy of chemotherapy, the rate of D2 lymph node clearance, R0 resection, complications, responses of neoadjuvant chemotherapy and survival condition between two groups (P > 0.05). The incidence of abdominal pain, diarrhoea, nausea and vomiting in the observation group were significantly lower than those in the control group (16.26% vs 29.63%, χ2 = 5.893, P < 0.05; 11.38% vs 26.85%, χ2 = 9.084, P < 0.05; 35.77% vs 53.70%, χ2 = 7.499, P < 0.05). The SOX regimen and mFOLFOX6 regimen have similar chemotherapy efficacy for locally advanced gastric cancer, but SOX regimen has a lower risk of gastrointestinal adverse reactions comparing with mFOLFOX6 regimen.

Adjuvant Temozolomide for the Treatment of Glioblastoma: A Meta-analysis of Randomized Controlled Studies.

INTRODUCTION: The efficacy of adjuvant temozolomide to radiotherapy for glioblastoma remained elusive. This meta-analysis aimed to explore the influence of radiotherapy plus adjuvant temozolomide on the efficacy and safety for glioblastoma. METHODS: We have searched several databases including PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through November 2020 and included randomized controlled trials assessing the efficacy and safety of adjuvant temozolomide to radiotherapy for glioblastoma. RESULTS: Seven randomized controlled trials and 1900 patients were included in the meta-analysis. Overall, compared with radiotherapy for glioblastoma, adjuvant temozolomide was associated with significantly increased survival rate [odds ratio (OR), 4.04; 95% confidence interval (CI), 2.61-6.24; P < 0.00001], median progression-free survival (mean difference, 0.55; 95% CI, 0.03-1.07; P = 0.04), and hematological complications (OR, 4.12; 95% CI, 1.43-11.88; P = 0.009), but revealed no remarkable influence on adverse events (OR, 0.87; 95% CI, 0.36-2.09; P = 0.75) or serious adverse events (OR, 2.20; 95% CI, 0.55-8.70; P = 0.26). CONCLUSIONS: Adjuvant temozolomide in combination with radiotherapy may improve the treatment efficacy for glioblastoma.
