Preoperative chemoradiotherapy may be beneficial for patients with advanced sinonasal cancer when primary radical surgery is challenging. Survival outcomes were comparable to outcomes reported in the literature despite conservative surgery and relatively low radiation doses in patients with locally advanced tumors.
To our knowledge, this is the first time ECM-related proteins have been shown to be affected by cranial radiotherapy in patients with cancer. These findings may help us to get a better understanding of the mechanisms behind side effects following radiotherapy.
Immunofluorescence quantification of γH2AX foci is a powerful approach to quantify DNA double-strand breaks induced by cancer therapy or accidental exposure to ionizing radiation. Here we report a modification to the γH2AX immunofluorescence labeling method, whereby cells are stained in-solution before being spotted and fixed onto microscope slides. Our modified method allows arraying of 16 patient samples/slide ready for foci counting in 2 h and demonstrated reliably detection of γH2AX foci in mononuclear cells prepared from patients who had undergone radiation therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
