Meta Analysis Comparative Study
A study-level meta-analysis of efficacy data from head-to-head first-line trials of epidermal growth factor receptor inhibitors versus bevacizumab in patients with RAS wild-type metastatic colorectal cancer.
Head-to-head trials comparing first-line epidermal growth factor receptor inhibitor (EGFRI) versus vascular endothelial growth factor inhibitor (bevacizumab) therapy yielded differing results, and debate remains over optimal first-line therapy for patients with RAS wild-type (WT) metastatic colorectal cancer (mCRC). ⋯ This meta-analysis supports a potential benefit for first-line EGFRI plus chemotherapy versus bevacizumab plus chemotherapy with respect to OS, ORR and ETS in patients with RAS WT mCRC. A patient-level meta-analysis is awaited.

To conduct a quantitative analysis of microcirculation blood perfusion in patients with hepatocellular carcinoma (HCC) before and after transcatheter arterial chemoembolisation (TACE) using contrast-enhanced ultrasound (CEUS). From 2013 June to 2105 October, a total of 106 HCC patients undergoing TACE were recruited. CEUS was performed before and after TACE to determine time-intensity curve (TIC) and perfusion quantitative parameters of the HCC lesions and surrounding liver parenchyma. ⋯ However, no significant differences were found in MVD between well-differentiated and poor-differentiated HCC lesions under a light microscope at 100× and 200× magnifications. The PI, ISI, AUC and BF of poor-differentiated HCC lesions were significant lower than those of well-differentiated HCC lesions, but there were no differences in AT, TTP, ACU, MTT, a2 and a3. In conclusion, these results indicate that quantitative CEUS perfusion parameters could be useful tools for assessing the efficacy of TACE for HCC.
