摘要: 目的:研究磁共振成像(MRI)测量和评估口腔黏膜鳞状细胞癌(oral squamous cell carcinoma,OSCC)临床分期指标的准确性。方法:纳入2020年2月—2022年9月就诊于中国科学技术大学附属第一医院的OSCC患者71例,记录MRI测量的肿瘤最大直径(maximum tumor diameter,MTD)、浸润深度(depth of invasive,DOI)以及最大值截面,按相应截面制作病理切片,测量病理MTD和DOI值并进行统计分析,将MRI图像评估的患者颈淋巴结状态与术后病理证实的淋巴结状态进行比较,分析术前MRI测量和评估临床分期的准确性。采用SPSS 26.0软件包对数据进行统计学分析。结果:MRI Gd-T1WI序列测量的DOI平均较病理结果高出2.54 mm(95%CI: 3.56~1.53,P<0.05),相关系数r为0.984;T2WI序列测量的DOI平均较病理结果高出3.09 mm(95%CI: 4.88~1.29,P<0.05),相关性系数r为0.953。Bland-Altman散点图显示,Gd-T1WI序列的测量结果与病理DOI值一致性更高。临床测量的MTD较病理结果高出0.85 cm(95%CI: 0.78~0.91,P<0.05),相关性系数r为0.958;MRI测量的MTD较病理结果高出0.21 cm(95%CI:0.10~0.32,P<0.05),相关性系数r为0.878。MRI测量肿瘤的MTD值较临床目测的结果误差显著降低。通过MRI术前评估患者颈淋巴结状态,真阳性率为69.6%,真阴性率为89.6%。结论:MRI在测量OSCC患者临床分期指标DOI和MTD的准确性较高,可作为评估患者临床分期的一种可靠的参考方法。

Abstract: PURPOSE: To investigate the accuracy of magnetic resonance imaging (MRI) for measuring and assessing the clinical staging of oral squamous cell carcinoma (OSCC). METHODS: A total of 71 patients with OSCC in The First Affiliated Hospital of University of Science and Technology of China from February 2020 to September 2022 were enrolled. The MRI measurements of maximum tumor diameter(MTD), depth of invasion(DOI), and maximum cut sections were recorded, pathological sections were made on the sections, the pathological MTD and DOI were measured and statistically analyzed, and the cervical lymph node status assessed by MRI was compared with the postoperative pathological lymph node status to analyze the accuracy of preoperative MRI measurements and clinical staging. SPSS 26.0 software package was used for data analysis. RESULTS: The mean DOI measured on the MRI was 2.54 mm(95%CI: 3.56-1.53, P<0.05), higher for Gd-T1WI sequence, with correlation coefficient r=0.984; the mean DOI measured on T2WI sequence was 3.09 mm(95%CI: 4.88-1.29, P<0.05) higher, with correlation coefficient r=0.953. Bland-Altman dot plots showed that the measurements of Gd-T1WI sequence were more consistent with pathological DOI values. At the same time, the clinical measurements of MTD were 0.85 cm (95%CI: 0.78-0.91, P<0.05), higher than the histologic findings, with correlation coefficient r of 0.958; the MRI measurements of MTD were 0.21 cm(95%CI: 0.10-0.32, P<0.05), higher than the histologic findings, with correlation coefficient r of 0.878. The MTD measured by MRI was significantly lower than that measured by clinical visualization. The preoperative assessment of cervical lymph node status by MRI was true-positive in 69.6% and true-negative in 89.6% of patients. CONCLUSIONS: MRI has a high accuracy in measuring clinical stage in patients with OSCC and can be used as a reliable reference method for assessing clinical stage.
