Progress on medication-related osteonecrosis of the jaw.

Medication-related osteonecrosis of the jaw (MRONJ) is a severe complication of bisphosphonates (BPs) or other targeted agent therapies. MRONJ appears as exposed bone, pus, and swelling in the oral and maxillofacial regions. However, neither surgery nor conservative therapy can eliminate symptoms thoroughly. In addition to BPs, several antiresorptive and antiangiogenic agents, such as denosumab an...

Bilateral Vitreous Hemorrhage Following Bilateral Intravitreal Injections of Bevacizumab in an Infant With Retinopathy of Prematurity.

Since the publication of BEAT-ROP in 2011, intravitreal bevacizumab (IVB) has become increasingly common for the treatment of posterior type 1 retinopathy of prematurity (ROP). However, long-term data on the safety and efficacy of IVB for ROP are lacking. Vitreous hemorrhage following bevacizumab injections have been rarely reported in infants with ROP, and the need for treatment of these hemorrha...

Laparoscopic repair of bevacizumab-induced vesicovaginal fistula in metastatic colon cancer - a video vignette.

Bevacizumab is a humanized monoclonal antibody targeting vascular endothelial growth factor (VEGF). Adding bevacizumab to a variety of first-line regimens used for metastatic colon cancer improves outcomes. Vesicovaginal fistula (VVF) is an extremely rare complication of bevacizumab, which has been reported in a few patients with metastatic cervical cancer. Here, we report a patient with metastat...

Lower-grade gliomas: the wrong target for bevacizumab.

ASO Author Reflections: Surgery and Bevacizumab in Ovarian Cancer.

Glioblastoma endothelium drives bevacizumab-induced infiltrative growth via modulation of PLXDC1.

Bevacizumab, a VEGF-targeting monoclonal antibody, may trigger an infiltrative growth pattern in glioblastoma. We investigated this pattern using both a human specimen and rat models. In the human specimen, a substantial fraction of infiltrating tumor cells were located along perivascular spaces in close relationship with endothelial cells. Brain xenografts of U87MG cells treated with bevacizumab ...
