摘　　要：目的:探究应用MR诊断宫颈癌侵犯周围结构与肿瘤分期的关系。方法:选取2019年1月—2023年2月在梧州市红十字会医院经病理证实的宫颈癌患者共51例,依据2018年宫颈癌的FIGO分期,以病理结果为参照,观察其侵犯周围结构的MR表现。结果:宫颈癌向周围结构的侵犯:累及阴道上2/3有43例,宫颈基质环不完整29例,累及阴道下1/3者2例,转移至盆腔淋巴结15例,转移至腹主动脉旁淋巴结、累及输尿管、侵犯直肠均为1例,侵犯膀胱2例。肿瘤分期分布:MR评价满足阴道上2/3受累的有40例合并Ⅱ期以上结构受累,以病理结果为金标准,准确度达93.02%(40/43);MR评价宫颈基质环不完整的有27例合并Ⅱb期以上结构受累,准确度达93.10%(27/29);MR评价转移至盆腔淋巴结的有14例合并Ⅲ期以上结构受累,准确度达93.33%(14/15);MR评价累及阴道下1/3、转移至主动脉旁淋巴结、累及输尿管引起肾积水、侵犯膀胱及直肠的病例同病理诊断一致。结论:MR对于宫颈癌侵犯周围结构及淋巴结转移显示好,可提高肿瘤分期的诊断准确率,是宫颈癌治疗前分期的重要手段。Objective MR Was used to investigate the relationship between cervical cancer invasion surrounding structure and tumor stage.Methods A total of 51 cervical cancer patients confirmed by pathology at the Red Cross Hospital in Wuzhou City from January 2019 to February 2023 were selected.According to the FIGO staging of cervical cancer in 2018 and the pathological results as a reference,the MR manifestations of invasion of surrounding structures were observed.Results The invasion of cervical cancer to the surrounding structures:43 cases involved the superior vaginal 2/3,29 cases with incomplete cervical stroma ring,2 cases with involved the inferior vaginal 1/3,15 cases with metastasis to pelvic lymph nodes,1 case with metastasis to para-abdominal aortic lymph nodes,1 case with ureter involvement,and 2 cases with bladder invasion.Staging distribution of tumors:40 cases were complicated with more than stageⅡinvolvement in MR evaluation,and the accuracy was 93.02%(40/43)according to the gold standard of pathological results,and the accuracy was 93.10%in 27 cases with incomplete cervical matrix ring evaluated by MR,with an accuracy of 93.10%(27/29).14 cases with metastasis to pelvic lymph nodes were evaluated by MR,with an accuracy of 93.33%(14/15).MR evaluation was consistent with pathological diagnosis in cases involving inferior vaginal 1,metastatic to paraaortic lymph nodes,hydronephrosis caused by ureter,and invasion of bladder and rectum.Conclusion MR can well demonstrate the invasion of surrounding structures and lymph node metastasis of cervical cancer,which can improve the diagnostic accuracy of tumor staging and is an important means of pre-treatment staging of cervical cancer.
