xrt怎么读

In two of the three patients with xRT-induced early side effects ( cystitis, diarrhea), the MN yield in PBL induced by ex vivo irradiation before xRT was significantly higher than in the other patients without xRT-induced side effects.

3例因xRT引起的早期副反应患者中，2例的PBL微核率明显高于无xRT引起副反应者。

The 3-year overall survival rate and disease-free survival rate in XRT group and RT group were 33.3%, 19.1% and 21.4%, 16.6%, respectively. The median survival time was 19 months and 14 months respectively.

XRT组与RT组的3年总生存率分别为33.3%和19.1%，无肿瘤进展生存率分别为21.4%和16.6%，两组的中位生存期分别为19和14个月。

A higher MN yield in 9 patients than that of their respective pre-xRT level for at least 48 months after the initiation of xRT, indicating the persistence of xRT-induced residual cytogenetic damage.

9例患者在初次放疗后至少48个月，PBL微核率高于相应的放疗前的水平，表明放疗诱导残留的细胞遗传学损害持续存在。
