The authors determined the mammographic appearance of breast carcinoma in African-American women and compared it with that in a white cohort.
The authors reviewed the mammograms, clinical records, and pathology records of 97 consecutive African-American women with 100 confirmed breast cancers and 110 white women with 111 confirmed breast cancers.
The mammograms obtained in African-American women were positive in 94 cases (94%), and those obtained in white women were positive in 99 cases (89%). Forty-seven percent of malignancies in African-American women appeared as calcifications, alone or with a mass, and 41% appeared as a mass only. There was no statistically significant difference in the frequency of these two findings between the African-American and the white populations. There was no statistically significant difference in the breast parenchymal pattern between the two groups. The most common tumor location in both races was the upper outer quadrant.
Breast carcinoma in African-American women is similar to that in white women in terms of mammographic appearance, location, and breast density. The mammographic appearance should not be an impediment to the detection of breast cancer in African-American women.
作者确定了非裔美国女性乳腺癌的乳腺X线表现，并将其与白人队列中的表现进行比较。
作者回顾了97例连续的患有100例确诊乳腺癌的非裔美国女性以及110例患有111例确诊乳腺癌的白人女性的乳腺X线照片、临床记录和病理记录。
非裔美国女性的乳腺X线照片94例（94%）呈阳性，白人女性的乳腺X线照片99例（89%）呈阳性。非裔美国女性中47%的恶性肿瘤表现为钙化，单独出现或伴有肿块，41%仅表现为肿块。这两种表现的频率在非裔美国人和白人人群之间无统计学显著差异。两组之间的乳腺实质模式无统计学显著差异。两个种族中最常见的肿瘤位置均为外上象限。
非裔美国女性乳腺癌在乳腺X线表现、位置和乳腺密度方面与白人女性相似。乳腺X线表现不应成为非裔美国女性乳腺癌检测的障碍。
