Tumor relapse after radiotherapy may be due to the upregulation of programmed cell death ligand 1 (PD-L1). We demonstrated that anti-PD-L1 antibody synergizes with radiation to control local and distal tumors. CD8+T cells mediated antitumor effects of the combination therapy by the reduction of myeloid-derived suppressor cells (MDSCs) via tumor-necrosis factor (TNF)-mediated signaling. Our stud...
We report a rare complication following parent-artery occlusion in a patient with radiation-induced carotid pseudoaneurysms. Both the right internal carotid artery pseudoaneurysm and the recurrent external carotid artery pseudoaneurysm were treated by parent-artery occlusion with coils. Although rebleeding was not observed after the second embolization, angiography and endoscopy at the 12-month...
Impact of Angiotensin Blockade on Symptomatic Radiation Necrosis Following Stereotactic Radiosurgery
The effects of thiamine (vitamin B1) on the level of spontaneous or radiation-induced genetic changes in human lymphocytes in vitro were studied. Cultured lymphocytes were exposed to increasing concentrations of thiamine (0-500 microg/ml) and irradiated with X-rays. The DNA damage was estimated as the frequency of micronuclei and apoptotic or necrotic morphological changes in fixed cells. The r...
