RESUMO
WHAT IS KNOWN AND OBJECTIVE: Aflibercept, a recombinant protein designed to suppress the vascular endothelial growth factor (VEGF) signalling pathway, has been used in patients with metastatic colorectal cancer (mCRC). We conducted the first meta-analysis to systematically review the efficacy and safety of aflibercept in mCRC. METHODS: PubMed Central/Medline, Embase and cochrane library were systematically searched for randomized controlled trials and single-arm clinical trials on aflibercept plus chemotherapy for the treatment of mCRC through 9 September 2021. RESULTS: Ten studies comprising 2049 patients met the inclusion criteria. The pooled estimate rates were 16.0% for 12mPFS, 64.4% for 12mOS, 32.5% for ORR, 83.5% for DCR, while the rates of III/IV AEs rate were 80.2% respectively. The pooled estimate rates were 16.8% for III/IV diarrhoea, 22.3% for III/IV hypertension, 29.5% for III/IV neutropenia, 7.3% for III/IV proteinuria and 8.6% for III/IV oral mucositis. CONCLUSIONS: Analysis of data from randomized controlled trials(RCT) and single-arm clinical trials confirmed the good efficacy of aflibercept plus chemotherapy in mCRC, while the safety of the treatment is concerning.

A new dammarane triterpenoid glycoside named cyclocarioside J (1) and other three known triterpenoid glycosides were isolated from the leaves of Cyclocarya paliurus. Based on ESI-MS, HR-ESI-MS, (1)H NMR, (13)C NMR, and 2D NMR techniques including (1)H-(1)H COSY, HMBC, HMQC, and NOESY correlations, the structure of cyclocarioside J was elucidated as (20S,24R)-epoxydammarane 3ß,12ß,25-trihydroxy-12-O-ß-d-quinovopyranosyl-3-O-α-l-arabinopyranoside.
