摘要

这项研究是在 DNA 损伤修复抑制剂中寻找使恶性肿瘤对质子辐射敏感的方法。研究发现，在存在 1-β-D-arabinofuranosylcytosine (AraC) 的情况下，每周五次总病灶剂量为 50 Gy 的质子辐照对 B16 小鼠黑色素瘤生长的抑制作用比不含 AraC 的相同辐照更明显（p < 0.05）。这种效应与AraC+Protons组一般细胞的增殖活性降低和癌症干细胞数量减少有关，有望进一步改善质子放疗。

Effects of Fractionated Proton Irradiation in Combination with 1-β-D-Arabinofuranosylcytosine on B16 Murine Melanoma In Vivo

This study is a search for means of sensitization of malignant tumors to proton radiation among DNA damage repair inhibitors. It has been found that in the presence of 1-β-D-arabinofuranosylcytosine (AraC), five weekly proton irradiations at a total focal dose of 50 Gy lead to a more pronounced inhibition of B16 murine melanoma growth than the same irradiation without AraC (p < 0.05 ). This effect, associated with a decrease in the proliferative activity of cells in the general population and a decrease in the number of cancer stem cells specifically in the AraC+Protons group, is promising for further improvement of proton radiotherapy.
