目的应用间质磁共振淋巴造影术(IMRL)对宫颈癌Ⅰa1期患者宫颈锥切术后进行随访,了解盆腔淋巴系统的转移情况。方法经宫颈锥切病理确诊为宫颈癌Ⅰa1期的患者8例,术后6个月开始行IMRL复查,每年1次,观察盆腔淋巴系统变化。结果 1例已复查4年,3次MR检查均未见盆腔淋巴转移;7例完成2年以上MR淋巴造影随访。1例随访1年11个月,其中1例术后半年左侧淋巴系统显影不良,6个月后再次复查显影良好。8例均未出现盆腔淋巴转移。结论 IMRL能很好反映宫颈癌Ⅰa1期锥切术后盆腔淋巴系统情况,是重要的随访方法。
Objective To observe the metastasis of pelvic lymphatic system after cervical conization by stage Ia1 cervical lymph node dissection by interstitial magnetic resonance lymphadenectomy (IMRL). Methods Eight cases of cervical cancer Ⅰa1 diagnosed by cervical conization were retrospectively reviewed at 6 months after operation. The changes of pelvic lymphatic system were observed once a year. Results One case had been reviewed for 4 years. No pelvic lymphatic metastasis was observed in 3 MR examinations. Seven cases were followed up for more than 2 years. One case was followed up for 1 year and 11 months. One case of the left lymphatic system developed poorly after six months, and was reexamined well after 6 months. No pelvic lymphatic metastasis was found in 8 cases. Conclusion IMRL can well reflect the situation of pelvic lymphatic system after Ⅰa1 conization in cervical cancer, which is an important follow-up method.
