An important question left unanswered is whether transrectal ultrasound will result in earlier diagnosis in African Americans. Tumor registry data for 1985 and 1990 for a predominantly African-American population were reviewed to determine whether transrectal ultrasound influenced the stage at diagnosis of prostate cancer. Diagnosis by ultrasound increased from 0% to 60% of cases in those 5 years. Curable diseases (stages A and B) increased from 38% to 57% of cases. It is concluded that transrectal ultrasound can increase the diagnostic yield of potentially curable disease in a predominantly African-American population.
一个尚未得到解答的重要问题是，经直肠超声检查是否会使非裔美国人得到更早的诊断。回顾了1985年和1990年以非裔美国人为主的人群的肿瘤登记数据，以确定经直肠超声检查是否影响前列腺癌的诊断分期。在这5年中，通过超声诊断的病例从0%增加到了60%。可治愈疾病（A期和B期）的病例从38%增加到了57%。得出的结论是，经直肠超声检查可以提高以非裔美国人为主的人群中潜在可治愈疾病的诊断率。
