宫颈癌原发灶磁共振影像特征预测淋巴结转移的初步探讨

目的：探讨磁共振成像（MRI）在预测宫颈癌淋巴转移的应用价值。方法：对南京大学附属鼓楼医院2011年1月至2015年6月宫颈癌患者的 MRI 及病理资料进行回顾性分析。结果：肿瘤最大径、宫颈浸润深度、宫旁侵犯的差异均有统计学意义（P 均＜0.05）。肿瘤最大径＞4 cm、宫颈浸润深度＞1／2、存在宫旁侵犯是淋巴结转移的独立影响因素（P 均＜0.05）。结论：肿瘤最大径、宫颈浸润深度、宫旁侵犯与宫颈癌淋巴结转移存在相关性，上述宫颈癌原发灶 MRI 影像特征有助于宫颈癌淋巴结转移的预测。

Prediction of Lymph Node Metastasis in Patients with Uterine CervicalCancer by MRI

Objective:To study the value of magnetic resonance imaging(MRI)in the prediction of metastatic lymph nodes in patient withuterine cervical cancer.Methods:The MRI and pathological data of patients with cervical cancer who underwent operation between January 2011 and June 2015 in Nanjing Drum Tower Hospital were retrospected and selected.Results:Single factor analysis showed that the differences of the biggest tumor diameter,cervical infiltration depth, parametrial invasion had statistical significance (P <0.05).Multi -factor analysis showed that tumor maximum diameter >4 cm,cervical infiltration depth >1 /2,existence ofparametrial invasion were independent impact factors for lymph node metastasis(P <0.05).Conclusions:The biggest tumor diameter,cervical infiltration depth and parametrial invasion were correlated with lymph node metastasis.The MRIcharacteristics of primary lesion of cervical cancer can help predict lymph node metastasis.
