目的分析微小乳腺癌的直接数字化X线征象,并探讨其与临床查体及病理的关系。方法回顾性分析经手术、病理证实的微小乳腺癌68例。采用直接数字化乳腺X线机后处理工作站屏幕阅读方式。结果X线征象为结节者39例,单纯钙化14例,结构紊乱8例,致密影7例,除单纯钙化外,其他征象伴有钙化者37例。临床触诊阳性42例,阴性26例。本组15例(占22%)为非浸润性癌,不可触及微小癌中46%为非浸润性癌。结论微小乳腺癌X线表现为结节、单纯钙化、结构紊乱或致密影,细钙化是微小癌重要X线征象。直接数字化X线摄影对诊断临床触诊阴性的微小乳腺癌有重要价值。
Objective To analyze the direct digital X-ray signs of minimal breast cancer and to explore its relationship with clinical examination and pathology. Methods Retrospective analysis of 68 cases of micro-breast cancer confirmed by surgery and pathology. Using direct digital mammography post-processing workstation screen reading. Results X-ray showed nodules in 39 cases, simple calcification in 14 cases, structural disorder in 8 cases and dense shadow in 7 cases. In addition to simple calcification, other signs were associated with calcification in 37 cases. 42 cases of clinical palpation positive, negative in 26 cases. The group of 15 cases (22%) of non-invasive cancer, 46% of non-invasive micro-cancer is non-invasive cancer. Conclusion Small breast cancer is characterized by nodules, simple calcification, structural disorder or dense shadow. Fine calcification is an important X-ray sign of micro-cancer. Direct digital radiography for the diagnosis of clinical palpation-negative breast cancer has important value.
