Abstract

African American men with localized prostate cancer are less likely than White men to receive a radical prostatectomy. This disparity may exist because African American men have prostate cancers that are more biologically aggressive. We investigated if similar stage cancers of African American men and White men show differences in cancer control after radical prostatectomy. Men with localized prostate cancer who underwent radical prostatectomy during a 6-yr period were stratified by race, and time to prostate-specific antigen recurrence was measured. We used Chi-square and t-tests to compare baseline clinical and pathological factors based on race. Cox proportional hazards model was used to determine effects of race on cancer control while controlling for baseline measures of cancer severity. There were 1,228 cases evaluated. At baseline, African American men were treated at a significantly younger age than White men (P = 0.0027) but showed no significant difference in prostate-specific antigen PSA, Gleason score, pathology stage, maximum tumor dimension, and surgical margin status. Multivariable Cox proportional hazards analysis controlling for cancer severity at prostatectomy revealed that cancer-free survival was not worse among African Americans compared to other subjects (P = 0.16). The responsiveness of prostate cancers among African American men to radical prostatectomy was similar to White men of similar stage and grade. Early detection in African American men may facilitate diagnosis of cancer amenable to prostatectomy. Studies are needed to evaluate the possible interaction of prostate cancer stage and grade shift in African American men and the disease free survival in this population.

摘要

患有局限性前列腺癌的非裔美国男性比白人男性接受根治性前列腺切除术的可能性更小。这种差异可能是因为非裔美国男性所患的前列腺癌在生物学上更具侵袭性。我们调查了非裔美国男性和白人男性处于相似分期的癌症在根治性前列腺切除术后的癌症控制情况是否存在差异。对在6年期间接受根治性前列腺切除术的局限性前列腺癌男性按种族进行分层,并测量前列腺特异性抗原复发时间。我们使用卡方检验和t检验来比较基于种族的基线临床和病理因素。在控制癌症严重程度基线指标的同时,使用Cox比例风险模型来确定种族对癌症控制的影响。共评估了1228例病例。在基线时,非裔美国男性接受治疗时的年龄显著低于白人男性(P = 0.0027),但在前列腺特异性抗原(PSA)、 Gleason评分、病理分期、最大肿瘤尺寸和手术切缘状态方面无显著差异。对前列腺切除术中癌症严重程度进行多变量Cox比例风险分析显示,与其他受试者相比,非裔美国人的无癌生存率并不更差(P = 0.16)。非裔美国男性前列腺癌对根治性前列腺切除术的反应与处于相似分期和分级的白人男性相似。非裔美国男性的早期检测可能有助于诊断适合进行前列腺切除术的癌症。需要开展研究来评估非裔美国男性前列腺癌分期和分级变化与该人群无病生存率之间可能存在的相互作用。
