目的提高钼铑双靶X线对早期乳腺癌诊断的准确性。方法对11例经手术及病理证实早期乳腺癌X线征象进行回顾性分析。结果早期乳腺癌征象:泥沙样微细钙化6例,X线未见明确肿块或结节而钙化灶为惟一恶性征象4例;非对称性密度增高3例;乳腺结构扭曲紊乱1例;局限性皮肤增厚伴乳头下陷1例。结论(1)泥沙样微细钙化仍是早期乳腺癌重要的诊断依据,甚至比直接征象(肿块)更具特异性。(2)非对称性局限性致密、乳腺结构局部扭曲紊乱,在排除炎症和手术史后,应考虑乳腺癌可能。(3)除恶性钙化外,大于两种间接征象并存时,应高度重视,予以进一步检查或短期复查。
Objective To improve the accuracy of dual-target molybdenum-rhodium X-ray in the diagnosis of early breast cancer. Methods Retrospective analysis of 11 cases of early breast cancer confirmed by surgery and pathology. Results Early signs of breast cancer: sediment-like calcification in 6 cases, no clear mass or nodules in X-ray and calcification as the only malignant sign in 4 cases; 3 cases of asymmetric density increase; 1 case of breast structure distortion disorder; Thickening of the skin with papillae in 1 case. Conclusions (1) Fine sediment-like calcification is still an important diagnostic basis for early breast cancer and even more specific than the direct signs (lumps). (2) Asymmetric limitations Dense, local distortion of the breast structure disorders, in the exclusion of inflammation and surgical history, breast cancer may be considered. (3) In addition to malignant calcification, more than two indirect signs coexist, we should attach great importance to further examination or short-term review.
