摘要
目的:探讨乳腺癌MRI间接征象与腋窝淋巴结转移的关系。方法:回顾性分析230例乳腺癌的MRI间接征象及间接征象的个数,术后腋窝淋巴结转移情况,根据淋巴结转移个数的多少分为pN0、pN1、pN2、pN34组。分析乳腺癌MRI间接征象及个数与N病理分期中淋巴结转移的关系,用Kruskal-Wallis秩和检验,P<0.05有统计学意义。结果:230例乳腺癌间接征象共442个,分别为水肿101例、血管增多152例、皮肤增厚及凹陷61例、乳头回缩69例、漏斗征16例、大导管征29例、彗星尾征4例、胸大肌受浸10例。pN0组乳腺癌有121例,间接征象191个;pN156例,间接征象109个;pN227例,间接征象65个;pN326例,间接征象77个。pN0-pN34组中乳腺癌MRI间接征象总体分布不等,Hc=20.09,P<0.010;pN0-pN34组中间接征象个数总体分布不等,统计结果Hc=26.41,P<0.005。结论:乳腺癌皮肤增厚凹陷、乳头凹陷及间接征象个数的多少对预测腋窝淋巴结转移有临床价值。
Objective: To explore the relationship between MRI indirect signs and axillary lymph node metastasis in breast cancer. Methods: MRI indirect signs and postoperative axillary lymph node metastasis of 230 with breast cancer patients were retrospectively analyzed.According to the number of lymph node metastasis,the cases were divided into four groups:pN0,pN1,pN2 and pN3.Kruskal-Wallis rank sum test was used to analyze the differences of MRI indirect signs of breast cancer among four groups. P <0.05 indicated statistical significance. Results: There were 442 indirect signs in 230 cases of breast cancer,including 101 cases of edema,152 cases of angiogenesis,61 cases of skin thickening and depression,69 cases with papillary retraction,16 cases with funnel sign,29 cases with large duct sign,4 cases of the comet tail sign and 10 cases of pectoralis major muscle infiltration.There were 121 cases of breast cancer in group pN0,with a total of 191 indirect signs;56 cases of breast cancer in group pN1 with a total of 109 indirect signs;27 cases of breast cancer in group pN2 with a total of 65 indirect signs;26 cases of breast cancer in group pN3 with a total of 77 indirect signs.The overall distribution of MRI indirect signs of breast cancer in pN0-pN3 four groups was different (Hc=20.09, P < 0.010),and the overall distribution of the number of indirect signs in pN0-pN3 groups was unequal (Hc=26.41, P <0.005). Conclusion: The number of cases of skin dimpling and thickening,crater nipples and indirect signs of breast cancer is clinical valuable in predicting axillary lymph node metastasis.
