目的观察X线钼靶乳腺摄像在乳腺癌新辅助化疗疗效评价中的作用。方法对比分析31例乳腺癌新辅助化疗前后钼靶乳腺摄像病灶各主要征象的变化,比较化疗前后乳腺肿块大小、形状、钙化、病灶周围等变化,并对其疗效进行判定。结果化疗后有31个病灶(占病灶总数81.6%)出现明显的变化,表现为肿块缩小、边界清晰、周围毛刺减少或消失、钙化减少或聚集;3个模糊形肿块、2个毛刺形肿块及2个钙化肿块未发生改变。结论钼靶摄像可清晰显示乳腺癌病灶及其化疗后变化,对乳腺癌新辅助化疗疗效评价具有一定的临床价值。
Objective To observe the role of mammography in mammography in evaluating the efficacy of neoadjuvant chemotherapy in breast cancer. Methods The changes of the main signs of mammography in 31 cases of breast cancer before and after neoadjuvant chemotherapy were analyzed. The changes of the size, shape, calcification and surrounding lesions were compared before and after chemotherapy. The curative effect was also evaluated. Results After chemotherapy, 31 lesions (81.6% of the total number of lesions) showed obvious changes, which showed that the tumor was reduced, the boundary was clear, the surrounding burr was reduced or disappeared, and the calcification was reduced or aggregated. Three fuzzy-shaped tumors, two prickles, Two calcified masses did not change. Conclusion Molybdenum target imaging can clearly show the location of breast cancer and its changes after chemotherapy. It has certain clinical value for evaluating the efficacy of neoadjuvant chemotherapy in breast cancer.
