彩色多普勒超声对乳腺癌癌周脉管癌栓的诊断价值

Value of color Doppler ultrasound in the diagnosis of breast cancer with vessel cancer embolus around carcinoma

目的探讨彩色多普勒超声血流检测技术对乳腺癌癌周脉管癌栓的诊断价值。方法回顾性分析101例乳腺癌,病理提示有癌周脉管癌栓者43例(有癌栓组),无癌栓者58例(无癌栓组),对照分析两组的二维超声图像及彩色多普勒血流显像。结果有癌栓组和无癌栓组比较,患者的年龄、肿块大小、组织学分级、有无腋窝淋巴结转移、彩色多普勒超声血流分级差异有统计学意义(P<0.05)。年轻、肿块大、组织学分级高、有腋窝淋巴结转移、超声血流分级高者,容易出现癌周脉管癌栓。结论乳腺癌癌周脉管癌栓与原发瘤肿块大小、病理组织学分级、超声血流分级、有无腋窝淋巴结转移及患者年龄密切相关,彩色多普勒超声对乳腺癌癌周脉管癌栓的术前评估有一定诊断价值。

Objective To investigate the diagnosis value of color Doppler ultrasound for breast cancer with vessel cancer embolus around carcinoma. Methods A retrospective analysis of 101 patients with breast cancer was performed, of them, 43 patients with breast cancer complicated by cancer embolus around carcinoma while the other 58 patients hadn＇t cancer embolus around carcinoma. Two-dimensional ultrasound images and color Doppler flow im- aging were compared between two groups. Results There were statistically significant difference in patient＇ s age, tumor size, histological grade, axillaries lymph node metastasis, color Doppler ultrasonic flow grade between two groups（P 〈 0. 05 ）. The younger patients, with larger mass size, higher histopathology grading, auxiliary＇ s lymph nodes metastasis and higher ultrasonic flow grade, were more prone to occurring of peritumoral vascular invasion. Conclusion The peritumoral vascular invasion of breast carcinoma had great relativity with size of primary mass, age of the patients, the classification of histopathology, ultrasonic flow grade and the metastasis of auxiliary＇ s lymph nodes. The color Doppler ultrasound had important clinical significance for breast cancer with vessel cancer embolus around carcinoma.
