将１８４例乳腺疾病患者分为乳腺癌组与非癌组，观察和比较两组钙化出现的频率和形态特征，分析乳腺癌组的钙化与病理分型，钙化与乳腺肿块的关系。乳腺癌组Ｘ线摄影显示钙化者为６４％（６０／９３），非癌组为２８％（２６／９１）。有钙化者患乳腺癌的相对危险性（ＲＲ）是没有钙化的４．５倍（Ｐ＜０．０１）。在显示钙化的乳腺癌组，４７％为浸润性导管癌，没有显示钙化的乳腺癌中，浸润性导管癌为２４％（Ｐ＜０．０５）；仅显示钙化但不伴有明显肿块影的占３８％（２３／６０）。典型的恶性钙化如泥沙样，细线样钙化有助于对Ｘ线摄影未显示肿块影的乳腺癌的诊断。
184 breast cancer patients were divided into breast cancer group and non-cancer group. The frequency and morphological characteristics of calcification in the two groups were observed and compared. The relationship between calcification and pathological type, calcification and breast mass in breast cancer group was analyzed. Mammograms showed a 64% (60/93) calcification in the breast cancer group and 28% (26/91) in the non-cancer group. The relative risk of breast cancer in patients with calcification (RR) was 4.5-fold less than that in patients without calcification (P <0.01). In the group showing calcified breast cancer, 47% were invasive ductal carcinomas, and no invasive ductal carcinomas were found in 24% of invasive ductal carcinomas (P <0.05); only calcifications were found but not accompanied by significant mass Accounting for 38% (23/60). Typical malignant calcifications such as sediment-like and fine-line calcification help to diagnose breast cancer that does not show mass in radiography.
