摘要
目的探讨MRI检出宫颈癌转移淋巴结大小及盆腔内分布特点。方法54例宫颈癌患者，采用PACS记录MRI检出淋巴结的影像特点，分析MRI检出宫颈癌淋巴结转移的敏感性、特异性。结果MRI检出宫颈癌淋巴结中闭孔区淋巴结检出率最高，左侧为88％，右侧为90％；髂内区淋巴结检出率次之，左侧为85％，右侧为88％；腹股沟深区淋巴结检出率左侧为79％，右侧为77％；髂外区淋巴结检出率左侧为45％，右侧为43％；髂总区淋巴结检出率左侧为31％，右侧为17％；转移组中5～10mm淋巴结占检出总数的51．2％；ROC曲线示以淋巴结直径判断检出淋巴结是否转移，取8mm时敏感性为49．5％，特异性为69．6％，AUC为0．669。结论MRI检出宫颈癌淋巴结主要分布在闭孔区及髂内区，腹股沟深区及髂外区次之；淋巴结直径不能判断转移与否。
Objective To explore the distribution characteristics and the sizes of lymph nodes detected by MRI in patients with cervical cancer. Methods Fifty-four patients with cervical cancer were recorded the MRI characteristics of lymph nodes by PACS. The sensitivity and specificity of MRI for lymph node metastases in cervical cancer were evaluated. Results The metastases rate in obturator lymph node was the highest （88% in the left side and 90~~ in the right side）. The internal iliac lymph nodes took the second place （86 % in the left side and 88 % in the right side）. The metastases rate was 79% in the left deep inguinal lymph nodes and 77% in the right side, 45% in the left external iliac lymph nodes and 43% in the right side, and was 31% in the left common iliac lymph nodes and 17% in the right side. Percentage of lymph nodes 5 to 10 mm in diameter was 51.2% in metastases group. According to ROC analysis, when lymph node was 8 mm in diameter, the sensitivity and specificity were 49.5% and 69.6 %, and AUC was 0. 669. Conclusions The metastasized lymph nodes by MRI detection are mainly located in the obturator and internal iliac lymph nodes, followed by the deep inguinal and external iliac lymph nodes lymph nodes. The diameter of lymph nodes could not be applied to estimate whether or not a metastasis develops.
