乳腺癌钼靶征象与淋巴结转移的相关性分析

Analysis of correlation between X - ray signs and lymph node metastasis of breast cancer

目的探讨乳腺癌钼靶征象与淋巴结转移的相关性。方法回顾性分析哈尔滨医科大学附属第三医院经过病理证实的乳腺癌病例62例，观察62例乳腺癌患者钼靶影像征象，采用下列5项指标进行分析：（1）病灶的形态；（2）病灶的边缘是否有毛刺；（3）病灶内或病灶邻近是否有钙化；（4）病灶的直径；（5）病灶的位置。统计数据采用SPSS15．0统计软件包，计数资料用X^2检验，P〈0．05认为差异有统计学意义。结果62例乳腺癌病例中，病灶边缘毛刺、病灶直径在淋巴结是否转移不同组中，差异均有统计学意义（P〈0．05）；而病灶的形态、病灶钙化及病灶位置在淋巴结是否转移不同组中，差异均无统计学意义（P〉0．05）。结论乳腺癌常见的钼靶影像表现中病灶边缘有毛刺、病灶的直径大于等于2cem的患者常出现淋巴结转移，有临床诊断意义；而病灶的形态是否为肿块、病灶内是否有钙化及病灶的位置对于乳腺癌患者是否有淋巴结转移无诊断意义。

Objective To study the correlation between X -ray signs and lymph node metastasis of breast cancer. Methods 62 cases of breast cancer who were pathologically confirmed were retrospectively ana-lysed. We observed their molybdenum target image signs by the following 5 indicators for analysis ： （ 1 ） form of the lesions, （2） whether there was burr at the edge of the lesions, （ 3 ） whether there was calcification within the le- sions or nearby, （4） size of the lesions, （5） lesions position. Data were analyzed using SPSS version 15. X^2 test was used for enumeration data,and P 〈 0.05 was considered as statistically significant. Results In the 62 cases of breast cancer,lesion size was greater than or equal to 2 cm, and burr at the edge of the lesion were statistically correlated with lymph node metastasis （ P 〈 0.05 ）. Whether the lesion is a mass, or there is calcification within the lesion or lesions position showed no statistical significance （P 〉 0.05 ）. Conclusion Lymph node metastasis often occur in breast cancer patients with mammography imaging signs of the lesion size greater than or equal to 2cm and burr at the edge of lesion, which are reliable signs for clinical diagnosis of lymph node metastasis. Whether the lesion is a mass or there is calcification within the lesion of lesions position have no significant corre-lation with lymph node metastasis in patients with breast cancer.
