计算机乳腺摄影对30～39岁妇女早期乳腺癌的诊断价值

The Diagnostic Value of Computerized Mammography for Early Breast Cancer in 30～39 Years Old Women

目的:探讨计算机乳腺摄影对30～39岁年龄组妇女早期乳腺癌的诊断价值。方法:应用意大利IMS公司生产的Giotto高频钼靶乳腺机和日本富士公司的CR系统对30～39岁年龄组妇女进行计算机乳腺摄影检查,回顾性分析由计算机乳腺摄影检出的乳腺癌和摄影发现异常继而活检的病理结果,并与同期40～49岁年龄组妇女计算机乳腺摄影及活检病理结果相对照。对127例手术病理证实的30～39岁年龄组妇女普通钼靶乳腺片及计算机乳腺摄影片采用双盲法进行对比研究。结果:对1020例30～39岁年龄组妇女进行计算机乳腺摄影检查,检出乳腺癌104例,873例无恶性肿瘤征象,对12例摄影发现的可疑病变进行了立体定位穿刺活检,7例为乳腺癌,其中2例导管原位癌,其余5例为浸润性癌。普通钼靶乳腺摄影及计算机乳腺摄影对早期乳腺癌的诊断有显著差异(P<0.05),计算机乳腺摄影优于普通钼靶乳腺摄影。结论:对30～39岁年龄组妇女进行计算机乳腺摄影检查,是发现年轻女性早期乳腺癌的有效方法。

Objective:To evaluate the clinical value of computerized mammography for diagnosing early breast cancer in younger women.Methods:We have reviewed the results of mammography in30～39years old women from December1998to September2000,and pathologi-cal outcome from biopsies recommended on the basis of computerized mammography also were reviewed.Data were compared with the results of computerized mammography and pathological findings in40～49years old women during the same period.The outcome from both molybdenum mammography and computerized mammography were contrasted using double～blind method in35～39years old breast cancer patients who were pathologically confirmed.Results:In a total of1020cases of30～39years old women,104patients were diagnosed breast cancer by computer-ized mammographic examination.In overall series,873cases showed no abnormalities.Twelve suspicious patients received stereotactic needle biopsy,7of them had breast cancer in which2intra ductal and5infiltrating cancer.Comparing molybdenum mammography with computerized mam mography,there was significant difference in early breast cancer(P<0.05).The results showed that computerized mammography was better than molybdenum mammography.Conclusion:Early breast cancer can be detected on computerized mammography.
