乳腺X线与高频彩色多普勒超声术前评估乳腺肿瘤大小的应用价值

目的:评估乳腺X线与高频彩色多普勒超声（超声）术前测量乳腺癌肿瘤大小的准确性。方法:术前乳腺X线、超声测量70例原发性乳腺癌肿瘤大小，以乳腺癌改良根治术后病理学测量的肿瘤大小为参考，进行比较分析。结果:绝经前患者术前乳腺X线所测肿瘤大小与术后病理大小呈正相关关系（P<0.05），而术前超声所测肿瘤大小与术后病理大小无相关关系（P>0.05）；绝经后患者术前乳腺X线、超声所测肿瘤大小与术后病理大小均呈正相关关系（P<0.05和P<0.01）。腋窝淋巴结无转移时，术前乳腺X线、超声所测肿瘤大小与术后病理大小均呈正相关关系（P<0.01和P<0.05）；腋窝淋巴结有转移时，术前乳腺X线、超声所测肿瘤大小与术后病理大小均无相关关系（P>0.05）。不考虑其他临床病理因素时，术前乳腺X线、超声所测肿瘤大小与术后病理大小均呈正相关关系（P<0.01和P<0.05）。结论:术前乳腺X线对乳腺癌肿瘤大小的评估优于乳腺超声。但在部分特殊的乳腺结构及疾病类型中，乳腺X线术前评估肿瘤大小准确性仍需深入研究。

Application value of mammography and color Doppler ultrasonography in the assessment of tumor size of breast cancer before operation

Objective:To evaluate the accuracy of mammography and color Doppler ultrasonography in the assessment of tumor size of breast cancer before operation. Methods:The tumor sizes in 70 patients with primary breast cancer before operation were measured using mammography and color Doppler ultrasonography,which was compared with the size of the tumor pathology after modified radical mastectomy. Results:The tumor size measured by mammography in premenopausal patients before operation was positive correlation with the postoperative breast cancer size measured by pathology(P<0. 05),the tumor size measured by color Doppler ultrasonography in premenopausal patients before operation was not correlation with the postoperative breast cancer size measured by pathology ( P>0. 05). The tumor size measured by mammography and color Doppler ultrasonography in postmenopausal patients before operation were positive correlation with the postoperative breast cancer size measured by pathology(P<0. 05 and P<0. 01). The tumor sizes measured by mammography and color Doppler ultrasonography in patients without axillary lymph node metastasis before operation were positive correlation with the postoperative breast cancer size(P<0. 01 and P<0. 05). The tumor sizes measured by mammography and color Doppler ultrasonography in patients with axillary lymph node metastasis were not correlation with the postoperative breast cancer size (P>0. 05). Excluding other clinical pathological factors,the tumor sizes measured by mammography and color Doppler ultrasonography before operation were positive correlation with the postoperative breast cancer size(P<0. 01 and P<0. 05). Conclusions:The accuracy of mammography in evaluating the tumor size of breast cancer is better than that of color Doppler ultrasonography. For some special structure and type breast,the accuracy of mammography in evaluating the tumor size still need to explore before operation.
