摘要
目的:探讨宫颈癌TVCDS影像学表现,并分析其与肿瘤特征的相关性.方法:回顾性分析本院2018 年12 月至2023 年11 月收治的98 例宫颈癌患者的临床资料(宫颈癌组),同期纳入 71 例TVCDS体检正常者作为对照组,收集两组 TVCDS 检查的影像学资料,对比不同人群血流信号分级、病理特征、RI、PSV及EDV值,并采用Spearman秩相关性分析宫颈癌患者 RI、PSV 及 EDV 与血流信号分级的关系.结果:宫颈癌组RI值低于对照组,PSV、EDV 值均高于对照组(P<0.05).宫颈癌不同临床分期患者RI值比较:Ⅰ期>Ⅱ期>Ⅲ期,PSV、EDV值比较:Ⅰ期<Ⅱ期<Ⅲ期,且肿瘤直径<40mm、无淋巴结转移患者RI值明显高于直径≥40mm、有淋巴结转移者(P<0.05).不同血流分级患者RI值比较:Ⅰ级>Ⅱ级>Ⅲ级,PSV、EDV值比较:Ⅰ级<Ⅱ级<Ⅲ级(P<0.05).相关性结果显示,RI与血流信号分级呈负相关(r=-0.411,P<0.001),PSV、EDV 与血流分级均呈正相关(r=0.396、0.408,P<0.001).结论:宫颈癌患者TVCDS检查RI、PSV及EDV值变化与其肿瘤病理特征、血流信号分级密切相关.
Abstract
Objective:To explore the imaging manifestations of cervical cancer on TVCDS(Transvaginal Color Doppler Sonography)and analyze their correlation with tumor characteristics.Methods:A retrospective analysis was conducted on the clinical data of 98 patients with cervical cancer(cervical cancer group)admit-ted to our hospital from December 2018 to November 2023.Concurrently,71 subjects with normal TVCDS re-sults during physical examinations were included as a control group.Imaging data from TVCDS examinations of both groups were collected.Comparisons were made between the groups regarding blood flow signal grading,pathological characteristics,RI(Resistance Index),PSV(Peak Systolic Velocity),and EDV(End-Dias-tolic Velocity).Spearman rank correlation analysis was used to assess the relationship between RI,PSV,EDV,and blood flow signal grading in patients with cervical cancer.Results:The RI value in the cervical cancer group was lower than that in the control group,while PSV and EDV values were higher(P<0.05).A-mong cervical cancer patients at different clinical stages,RI values were compared as follows:Stage I>StageⅡ>Stage Ⅲ.In contrast,PSV and EDV values were compared as follows:Stage I<Stage Ⅱ<Stage Ⅲ.Patients with tumor diameter<40mm and no lymph node metastasis had significantly higher RI values than those with tumor diameter≥40mm and lymph node metastasis(P<0.05).Comparisons of RI values among patients with different blood flow signal grades were as follows:Grade I>Grade Ⅱ>Grade Ⅲ.PSV and EDV values were compared as follows:Grade I<Grade Ⅱ<Grade Ⅲ(P<0.05).Correlation results indica-ted that RI was negatively correlated with blood flow signal grading(r=-0.411,P<0.001),while PSV and EDV were positively correlated with blood flow signal grading(r=0.396,0.408,P<0.001).Conclusion:Changes in RI,PSV,and EDV values on TVCDS in patients with cervical cancer are closely related to their tumor pathological characteristics and blood flow signal grading.
