ABSTRACT

Objective To explore the essentiality of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) examination before breast-conserving surgery (BCS) in breast cancer patients with young women.Methods The data of DCE-MRI and mammography X-ray in 30 breast cancer patients with young women (＜ 40 years old) who received surgery with pathology-proven were retrospectively analyzed.The detection rate of breast lesion,number,size,extent of invasive and lymph node metastasis of preoperative were observed.The DCE-MRI was assessed accuracy of BCS in accordance with indications for BCS and histopathology results.Results The breast cancer detection rate of DCE-MRI was significantly higher than mammography X-ray [100.00％(30/30) vs.73.33％(22/30),P =0.002].The maximum tumor diameter of DCE-MRI was (3.55 ± 1.50) cm,mammography X-ray was (3.38 ± 1.70) cm,postoperative pathology was (3.51 ± 1.20) cm,and DCE-MRI was closer to postoperative pathology than mammography X-ray.The discovery of additional lesions of DCE-MRI was more than mammography X-ray (P ＜ 0.05).The surrounding tissue invasion of DCE-MRI was detected in 22 cases,mammography X-ray was in 9 cases,postoperative pathology was in 19 cases,there was no significant difference between DCE-MRI and postoperative pathology (P =0.598),there was significant difference between mammography X-ray and postoperative pathology (P =0.010).The number of axillary fossa lymph node metastasis of DCE-MRI was in 127,mammography X-ray was in 48,compared with postoperative pathology (91),there was significant difference (P =0.026,0.034).The detection of microcalcification of mammography X-ray was better than DCE-MRI (7 cases vs.0 case,P =0.001).The number of BCS of postoperative pathology was in 12 cases,DCE-MRI was in 11 cases,mammography X-ray was in 8 cases,DCE-MRI was higher than mammography X-ray,but there was no significant difference (P=0.132).Conclusion DCE-MRI provides comprehensive and accurate information for breast cancer patients with young women for BCS,and it is feasible to assess them using DCE-MRI preoperative for BCS.
