钼靶乳腺摄像在乳腺癌新辅助化疗疗效评价中的应用

Application of molybdenum target mammography to evaluation of neoadjuvant chemotherapy in breast cancer

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 molybdenum target mammography in the evaluation of neoadjuvant chemo- therapy （NCT） in breast cancer. Methods The major signs of lesions of 31 cases of breast cancer were compared before and after NCT. The changes in the size, shape and calcification of the tumors and other changes around the lesion were also compared. The curative effect was evaluated. Results After chemotherapy,31 of the 38 lesions （81.6%） underwent sigr ~fieant changes. The results showed that tumors shrank, their boundary became clear, the peripheral burr of lesions de- creased or disappeared and calcification was reduced or aggregated. Three unclear margin lesions, two glitch ones and two calcified ones hardly changed. Conclusion Molybdonum target mammography can clearly show lesions and their changes in breast cancer after chemotherapy.
