BACKGROUND A previous study has shown that shorter bevacizumab infusions (0.5 mg/kg/min) can be safely administered without increasing the risk of infusion-related hypersensitivity reactions (HSRs). However, the risk of proteinuria and hypertension in patients receiving shorter infusions of bevacizumab is undetermined. PATIENTS AND METHODS This was a multicenter, prospective, observational st...
Colorectal cancer (CRC) is a common tumor type with a high mortality rate, in part due to intrinsic drug resistance. Although bevacizumab, a VEGF-directed neutralizing antibody, is particularly active in this pathology, some patients never respond for reasons not well understood. We here wish to clarify the role of autocrine VEGF signaling in the response of CRC cells to angiogenesis inhibition...
OBJECTIVE The SOFT study previously demonstrated that S-1 and oxaliplatin (SOX) plus bevacizumab was non-inferior to l-leucovorin, fluorouracil and oxaliplatin (mFOLFOX6) plus bevacizumab in terms of the primary end point of progression-free survival (PFS) as first-line chemotherapy for metastatic colorectal cancer (mCRC). The overall survival (OS) data were immature at the time of the primary ...
Bevacizumab (Avastin, Genentech) is a potent inhibitor of vascular endothelial growth factor A that has demonstrated modest antitumor activity across a broad range of malignancies when combined with chemotherapy. In colorectal cancer, bevacizumab in combination with chemotherapy is a standard of care for first-line therapy, and is used as second-line therapy in both bevacizumab-naive patients a...
AIM Bevacizumab has been reported to result in increased tumor invasion when used to treat malignant glioma. We hypothesized that BMP4 would prevent diffuse tumor infiltration induced by bevacizumab for malignant glioma in a xenograft model. METHODS Human glioblastoma (GBM) tumor cells were implanted in the striatum of immunocompromised mice. The animals were treated with bevacizumab and BMP4...
BACKGROUND Bevacizumab is an antiangiogenic compound developed to target tumour vessels. Its off-label use in ophthalmology requires in vitro testing on ocular cells. AIM To quantify the antipermeability and antiproliferative effects of bevacizumab on cultured choroidal endothelial cells (CECs). It was examined whether deep-freezing of bevacizumab attenuates its antiangiogenic activity. MET...
OBJECTIVE Bevacizumab has been shown to be effective in the treatment of recurrent glioblastoma in combination with chemotherapy compared with historic controls but not in randomized trials. METHODS We conducted a retrospective analysis of patients treated for recurrent glioblastoma with bevacizumab vs a control group of patients, comparing progression-free survival (PFS) and overall survival...
Women with high-risk HER2-negative breast cancer do not benefit from the addition of bevacizumab (Avastin, Genentech) to standard chemotherapy, according to results from the Eastern Cooperative Oncology Group 5103 (E5103) trial. “Our results are quite similar to those reported previously for the BEATRICE and the BETH trials, which enrolled patients with HER2-positive disease,” said presenter Dr...
OBJECTIVE This retrospective study investigated the efficacy and safety of bevacizumab treatment for refractory brain edema. METHODS Between March 2009 and December 2015, bevacizumab was used to treat 59 cases of brain metastatic patients with refractory brain edema. The median dose of bevacizumab was 4.68 mg/kg (range 2.8-6.52 mg/kg). The clinical-pathological data, the efficacy, and the sid...
Intravenous bevacizumab decreased mucosal bleeding in some patients with hereditary hemorrhagic telangiectasia (HHT). We treated a 47-year-old male who had HHT, severe epistaxis, and gastrointestinal bleeding, alcoholic cirrhosis, and portal hypertension with intravenous bevacizumab 2.5 mg/kg every 2 weeks. We tabulated these measures weekly during weeks 1-33 (no bevacizumab); 34-57 (bevacizuma...
