数字化X线摄影在触诊阴性乳癌中的诊断价值

The value of full-field digital mammography in the diagnosis of nonpalpable breast cancer

目的探讨数字化乳腺X线摄影对隐性乳癌的诊断价值。方法回顾性分析我院2004年2月-2006年12月门诊体检中遇到的32例未触及肿块乳癌。术前均行金属丝定位,并经病理证实。结果X线呈现单纯钙化16例,其中癌前病变3例,导管原位癌6例,浸润性导管癌7例;微结节或致密影伴钙化5例,其中癌前病变1例,导管原位癌2例,浸润性导管癌2例;呈现不对称性致密影5例,1例为小叶原位癌,4例为浸润性导管癌;微结节伴浅分叶或毛刺4例,其中1例为导管原位癌,3例为浸润性导管癌;结构紊乱2例,均为浸润性导管癌。结论数字化乳腺X线摄影对诊断未触及肿块的触诊阴性乳癌、提高患者生存率、降低病死率、以及开展保乳手术具有重大价值。

Objective To investigate the evaluaton of full-field digital mammography in the diagnosis of nonpalpable breast cancer.Methods During Feb.2004 to Dec.2006,32 cases of nonpalpable breast cancer were found on digital mammogram in physical examination,all were verified by pathology.X-ray guided wire localization was conducted before operation.Results Microcalcifications were found on digital mammogram in 16 cases, 3 of these was disease before cancer, 6 were ductal carcinoma in situ, 7 were infiltrating ductal carcinoma; Micronodule or increase of local density on mammogram with calcification was found in 5 cases, 1 was disease before cancer and 2 were lobubar carcinoma in situ,2 were DCIS; Of 5 cases with asymmetrical increase of local density on mammogram,one was lobubar carcinoma in situ, another 4 were infiltrating ductal carcinoma;Multilobular small nodes was found in 4 cases, 1 of these was DCIS,3 were infiltrating ductal carcinoma;Architectural distortion was found in 2 case, pathological examination were infiltrating ductal carcinoma. Conclusion There was important evaluation of full-field digital mammography for diagnosing nonpalpable breast cancer, improving subsistence rate,decreasing mortality rate and performing partial breast operation.
