彩色多普勒超声在评估乳腺癌手术前辅助性化疗效果的价值

目的探讨彩色多普勒超声检查在评估乳腺癌手术前辅助性化疗效果的价值。方法选取2015年1月~2021年1月安徽省肿瘤医院术前采取辅助化疗方式治疗的88例乳腺癌患者作为研究对象，根据化疗效果将患者分为有效组（n=60）和无效组（n= 28），对比两组化疗前后的原发病灶大小、病灶内血流分级特征、超声声像特征差异。结果化疗前，有效组和无效组患者的病灶长、宽、厚、病灶面积、病灶体积测定值差异无统计学意义（P>0.05）；化疗后，有效组患者的病灶长、宽、厚、病灶面积、病灶体积测定值均低于无效组（P < 0.05），两组患者的病灶长、宽、厚、病灶面积、病灶体积测定值较化疗前均降低（P < 0.05）；化疗前，有效组和无效组患者的病灶形态、边界、强回声带、后方回声构成情况差异无统计学意义（P>0.05）；化疗后，有效组患者肿瘤病灶规则形态、边界清晰、后方回声无异常的占比均高于化疗无效组，差异具有统计学意义（P < 0.05）；化疗前，有效组和无效组患者的肿瘤病灶血流分级构成情况差异无统计学意义（P>0.05）；化疗后，有效组患者肿瘤病灶血流分级达到（0级+Ⅰ级）占比高于无效组，差异具有统计学意义（P < 0.05）。结论彩色多普勒超声可以从病灶大小、血流分级、声像特征变化3个方面评估乳腺癌术前辅助性化疗效果，对于指导临床治疗及手术具有重要价值。

The value of color doppler ultrasonography in evaluating the efficacy of neoadjuvant chemotherapy in patients with breast cancer

ObjectiveTo explore the value of color Doppler ultrasonography (CDFI) in evaluating the effect of adjuvant chemotherapy before breast cancer surgery.MethodsFrom January 2015 to January 2021, 88 patients with breast cancer who were treated with adjuvant chemotherapy before surgery in our Hospital were selected. According to the effect of chemotherapy, the patients were divided into effective group of 60 cases and ineffective group of 28 cases. The two groups of chemotherapy were compared. The size of the primary lesion, the grading characteristics of blood flow in the lesion, and the characteristics of ultrasound imaging before and after were compared.ResultsBefore chemotherapy, the differences of the length, width, thickness, lesion area, and volume of the lesion between two groups were not significant (P>0.05). After chemotherapy, the length and width of the lesion, thickness, lesion area, and lesion volume in effective group were lower than those of ineffective group (P < 0.05). The measured values of lesion length, width, thickness, lesion area, and lesion volume of the two groups were all lower than those before chemotherapy (P < 0.05). Before chemotherapy, the differences of the morphology, border, hyperechoic band, and posterior echo composition between two groups were not significant (P>0.05). After chemotherapy, the tumor lesions in the effective group had regular morphology and borders. The proportions of clear and no abnormal back echoes were higher than those in the chemotherapy-ineffective group(P < 0.05). Before chemotherapy, there was no difference of the blood flow classification of tumor lesions between two groups (P>0.05). After chemotherapy, the proportion of patients in the effective group with tumor lesion blood flow classification (grade 0+Ⅰ) was higher than that in the ineffective group(P < 0.05).ConclusionColor Doppler ultrasonography can evaluate the effect of adjuvant chemotherapy before surgery for breast cancer from three aspects: lesion size, blood flow grade, and changes in acoustic and image characteristics. It is of great value for guiding clinical treatment and surgery.
