3.0T磁共振成像在早中期宫颈癌术前评估中的应用

摘要

Objective To evaluate the value of 3.0T magnetic resonance imaging (MRI) in preoperative assessment of cervical cancer in the early_middle stage. Methods A total of 53 patients with cervical cancer in the early_middle stage in Affili_ated Hospital of Jiangsu University from January 2008 to June 2014 were selected ,which were conducted by MRI routine scan and enhanced scanning,MRI staging and lymphatic metastasis judging. The International Federation of Gynecology and Obstetrics (FIGO) staging was performed according to clinicopathological information. The reliability of MRI staging and lymphatic metastasis judg_ing on cancer was compared with FIGO and postoperative pathologic results ,which were used as gold standard. Results It was suspected Ia in 5 cases,Ⅰb in 22 cases,Ⅱa in 22 cases,Ⅱb in 4 cases by preoperative MRI staging,whileⅠa in 6 cases,Ⅰb in 23 cases,Ⅱa in 21 cases,Ⅱb in 3 cases diagnosed by FIGO stage. There was no statistically significant difference between MRI staging and FIGO(P>0.05). 38 of 51 lymph node metastasis suspected by MRI was confirmed pathologically. It was also found 11 metastasis lymph nodes pathologically while MRI failed to detect,which had no statistically significant difference between them (P>0.05). Conclusion MRI may make more accurate evaluation to staging and lymph node metastasis of cervical cancer.%目的：评价3.0T磁共振成像（MRI）在早中期宫颈癌术前评估中的应用价值。方法选择2008年1月至2014年6月在江苏大学附属医院经手术治疗的53例早中期宫颈癌患者，术前行MRI平扫及增强扫描，并行MRI分期和淋巴结转移判断。术后综合临床及病理行国际妇产科联盟（FIGO）分期。以FIGO分期为“金标准”，评价MRI分期可靠性；以术后病理为“金标准”，评价MRI判断淋巴结转移的可靠性。结果术前MRI拟诊Ⅰa期5例、Ⅰb期22例、Ⅱa期22例、Ⅱb 期4例，术后FIGO分期Ⅰa期6例、Ⅰb期23例、Ⅱa期21例、Ⅱb 期3例，二者比较，差异无统计学意义（P>0.05）。术前MRI拟诊51枚淋巴结转移中38枚被病理证实，病理另发现MRI未发现的11枚淋巴结转移，二者比较，差异无统计学意义（P>0.05）。结论术前MRI能对宫颈癌分期及淋巴结转移作出准确评估。
