In an effort to determine the impact of race on the stage of prostate cancer at presentation, the records of 2102 patients diagnosed in Chicago between 1985 and 1987 were reviewed. For each of three age groups (less than 65, 65 to 75, and greater than 75 years), blacks had a significantly (P less than .05) lower percentage of localized stage disease than whites. Inasmuch as stage at diagnosis is inversely related to survival, these data may explain in part why prostate cancer mortality in every age category is higher for blacks than whites nationally.
为了确定种族对前列腺癌初诊时分期的影响,我们回顾了1985年至1987年在芝加哥确诊的2102例患者的记录。在三个年龄组(小于65岁、65至75岁、大于75岁)中,黑人局限性疾病分期的比例均显著低于白人(P<0.05)。鉴于确诊时的分期与生存率呈负相关,这些数据可能部分解释了为何在全国范围内,各年龄段黑人的前列腺癌死亡率均高于白人。
