Preclinical studies have demonstrated increase of cancer cells killing in vitro and marked antitumor efficacy in vivo with presence of these nanoparticles (HfO2-NP) exposed to RT, when compared to RT alone. [\u2026]<\/p>\n<p><strong>Material and Methods:<\/strong> CT26 (murine colorectal cancer cells) were subcutaneously injected in the flank of BALB\/c mice. Once the mean tumors volume reached 115\u00b130 mm3, tumors were intratumor injected with HfO2-NP and irradiated with 2Gyx3 or 4Gyx3, or irradiated only. Tumors were collected 5 days after the last RT fraction and analyzed for immune cell infiltrates by immunohistochemistry (2Gyx3 and 4Gyx3) and cytokines content by flow cytometry (2Gyx3). [\u2026]<\/p>\n<p><strong>Results:<\/strong> In mice bearing CT26 tumors, a marked increase of cytokines content and immune cell infiltrates was observed with HfO2-NP + 2Gyx3 when compared to RT alone. The tumor immune cell infiltrates were<br \/>\nfurther enhanced with HfO2-NP + 4Gyx3. In mice inoculated with 4T1 cells treated with HfO2-NP + 40Gy, a marked increase of immune cell infiltrate (CD8+) was observed in tumors when compared to tumors in mice inoculated with 4T1 cells treated with 40Gy and control.<\/p>\n<p><strong>Conclusions:<\/strong> These in vivo data generated from CT26 and 4T1 tumor models suggest that HfO2-NP + RT triggers immunogenic conversion of the tumor microenvironement when compared to RT alone. HfO2-NP treatment may represent a therapeutical approach for broad applications since it does not rely on any molecular characteristics of the tumor.[\/az_box_icons][vc_empty_space height=\u00a0\u00bb60px\u00a0\u00bb responsive_lg=\u00a0\u00bbhidden\u00a0\u00bb responsive_md=\u00a0\u00bbhidden\u00a0\u00bb][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]<\/p>\n<\/section>","protected":false},"excerpt":{"rendered":"<p>Hafnium oxide, an electron-dense material, was designed at the nanoscale to increase the radiation dose deposited from within the cancer cells: \u201cHot spot\u201d of energy deposit where the nanoparticles are when exposed to radiation therapy (RT).
