Laterality was examined in 10,702 cases of breast cancer in Israeli Jewish women. The overall left-right ratio was 1.04 and was higher in women over 60. The only population group with a left-right ratio less than 1 was the group of women born in Asian and Middle Eastern countries outside of Israel. There were no differences between the survival curves of women with right- or left-sided breast cancers at any stage. It is concluded that laterality of tumor is not an indicator of survival in breast cancer.
对10702例以色列犹太女性乳腺癌患者的肿瘤位置偏向性进行了研究。总体左右比例为1.04,60岁以上女性的该比例更高。左右比例小于1的唯一人群是出生在以色列以外亚洲和中东国家的女性群体。在任何阶段,右侧或左侧乳腺癌女性的生存曲线均无差异。研究得出结论,肿瘤位置偏向性并非乳腺癌生存的指标。
