全数字化乳腺X线摄影在乳腺癌新辅助化疗疗效评价上的应用

目的探讨全数字化乳腺X线摄影评价乳腺癌新辅助化疗疗效的应用价值．方法21例经穿刺活检确诊为乳腺癌患者，在新辅助化疗方案前后分别进行全数字化乳腺x线摄影，比较化疗前后乳腺肿块、局部腺体致密、结构扭曲、钙化等病灶变化情况，并对其疗效进行判定．结果化疗后有11例肿块较前减小；5例患者局部腺体致密范围缩小，1例范围扩大；4例结构扭曲较前改善；10例钙化中有6例未发生改变，3例钙化数量减少，1例钙化数量增多．结论全数字化乳腺X线摄影可清晰显示乳腺癌病灶，对乳腺癌新辅助化疗疗效评价具有一定的临床价值．

Application of Full-Field Digital Mammography in Curative Effect Assessment of Neo-adjuvant Chemotherapy of Breast Cancer

Objective To study the application value of response to neo-adjuvant chemotherapy of breast cancer by using full-field digital mammography. Method 21 patients with breast cancer finally diagnosed by needle aspiration examination accepted full-field digital mammography, and the changes of breast turnout,focus density, focal grand architectural distortion and calcifications were compared before and after neo-adjuvant chemotherapy, and the patients＇ curative effects were evaluated. Results 11 breast turnout after NCT were smaller than that before NCT;5 focus density scope reduced,and case enlarged ;4 focal grand architectural distortion improved ;In 10 calcification,6 cases were the same, 3 cases reduced, and 1 case increased. Conclusion Full-field digital mammography can clearly perform breast cancer shape, which has clinicall value for curative effect assessment of neo-adjuvant chemotherapy of breast cancer.
