目的使用多普勒彩色超声仪评价乳腺癌患者保乳术后放疗的疗效。方法使用多普勒彩色超声仪对25例女性乳腺癌患者进行疗效评价,主要包括患者放疗前后血管分布分级和血流阻力情况,2年内的双乳、腋下、甲状腺和颈部淋巴结复发情况及放疗后并发症。结果 16例患者疗效为完全缓解,5例患者为部分缓解,3例患者放疗前后比较无变化,只有1例患者出现了进展的情况。放疗前后患者平均血流阻力指数存在明显差异(P<0.05)。在术后放疗和未放疗患者2年内的复发率分别为16%和48%。而患者并发症的情况,放疗组的患者比未进行放疗的对照组患者多。结论多普勒超声检测能够显示绝大多数乳腺癌患者在放疗后病灶变化,放疗后乳腺癌内血管分布分级情况,术后2年内复发率等,可对乳腺癌患者放疗后的疗效进行良好的评价。
Objective To evaluate the efficacy of radiotherapy after breast-conserving surgery in breast cancer patients by using Doppler color sonography. Methods Twenty-five female patients with breast cancer were evaluated by Doppler sonography, including the distribution of blood vessels and blood flow resistance before and after radiotherapy, the relapse of breast, axillary, thyroid and cervical lymph nodes within 2 years and Post-radiotherapy complications. Results The curative effect was completely relieved in 16 patients, partial remission in 5 patients, no change in 3 patients before and after radiotherapy, and only 1 patient showed progress. The mean blood flow resistance index of patients before and after radiotherapy was significantly different (P <0.05). The recurrence rates within two years of postoperative radiotherapy and no radiotherapy were 16% and 48%, respectively. In the case of patient complications, there were more patients in the radiotherapy group than those in the control group who did not receive radiotherapy. Conclusion Doppler ultrasonography can show the changes of lesions in most breast cancer patients after radiotherapy, the blood vessel classification in breast cancer after radiotherapy and the relapse rate in 2 years after operation, which can improve the efficacy of radiotherapy in breast cancer patients Evaluation.
