To investigate the role of transrectal ultrasound guidance in interstitial brachytherapy for cervical cancer.
Forty-eight patients who underwent interstitial brachytherapy treatment for cervical cancer between January 2017 and January 2018 were enrolled in the study. The distances between each inserted needle and the lesion were measured at seven sites by ultrasound (D1-D7) and compared to the corresponding distances (M1-M7) when visualised with nuclear magnetic resonance imaging (MRI). Measurements were paired on the basis of the observation sites, e.g. D1 and M1, D2 and M2. The statistical differences, intraclass correlation coefficients (ICCs), and linear relationships for the paired measurements were calculated.
No significant differences were found between the paired M and D measurements, with all ICCs showing high levels of concordance (0.81-0.93).
Transrectal ultrasound showed strong agreement with MRI results in determining the position of the inserted needles. Transrectal ultrasound is a useful tool for guided interstitial brachytherapy and is appropriate for widespread use in the treatment of locally advanced cervical cancer.
探讨经直肠超声引导在宫颈癌组织间近距离治疗中的作用。
纳入2017年1月至2018年1月期间接受宫颈癌组织间近距离治疗的48例患者。通过超声在七个部位测量每根插入针与病变之间的距离（D1-D7），并与磁共振成像（MRI）显示时的相应距离（M1-M7）进行比较。测量值根据观察部位进行配对，例如D1和M1、D2和M2。计算配对测量的统计差异、组内相关系数（ICC）和线性关系。
配对的M和D测量值之间未发现显著差异，所有ICC均显示出高度一致性（0.81-0.93）。
经直肠超声在确定插入针位置方面与MRI结果高度一致。经直肠超声是引导组织间近距离治疗的有用工具，适用于局部晚期宫颈癌治疗的广泛应用。
