To determine the clinical presentation and outcomes of prostate cancer in human immunodeficiency virus (HIV)-infected men compared with HIV-uninfected men in an urban setting.
A retrospective cohort study of prostate cancer stage at diagnosis and mortality comparing HIV-infected patients with HIV-uninfected patients from 2000 to 2011 was carried out. Clinical features, HIV history, cancer presentation, and outcomes were reviewed. Cox proportional hazards analysis was performed to estimate the association between HIV status and mortality.
A total of 54 HIV-infected subjects were identified and reviewed, and 49 of them had complete data available; they were compared with 1496 HIV-uninfected subjects with prostate cancer. HIV-infected subjects were younger (median age, 60.7 vs 64 years) and had a higher proportion of African Americans (92% vs. 45%). An elevated prostate-specific antigen (PSA) level (76%) was the predominant indication for biopsy; 10 patients (27%) with an elevated PSA level had normal findings on digital rectal examination. Eighteen men (37%) presented with stage III and IV disease compared with 14% in the general population (P <.001). Eight patients (16%) died of prostate cancer. Subjects with HIV progressed to death at a significantly faster rate than those in the general population (adjusted hazard ratio, 2.02; 95% confidence interval, 1.14-3.58).
HIV-infected patients in this cohort presented with more advanced stage disease compared with the general population even though the majority were detected by screening PSA. The overall mortality rate was higher for HIV-infected patients with prostate cancer after controlling for race, tumor stage at diagnosis, and age. Prostate cancer screening methods may need to be individualized for HIV-infected men.
在城市环境中,比较 HIV 感染者和未感染者前列腺癌的临床表现和结局。
对 2000 年至 2011 年期间诊断时前列腺癌分期和死亡率的 HIV 感染者和未感染者进行回顾性队列研究。回顾了临床特征、HIV 病史、癌症表现和结局。采用 Cox 比例风险分析估计 HIV 状态与死亡率之间的关联。
共确定并回顾了 54 例 HIV 感染者,其中 49 例有完整数据;并与 1496 例患有前列腺癌的 HIV 未感染者进行比较。HIV 感染者年龄较小(中位数年龄,60.7 岁 vs. 64 岁),且非裔美国人的比例较高(92% vs. 45%)。升高的前列腺特异性抗原(PSA)水平(76%)是活检的主要指征;10 例 PSA 升高的患者(27%)直肠指检未见异常。18 例(37%)男性表现为 III 期和 IV 期疾病,而一般人群中这一比例为 14%(P <.001)。8 例(16%)死于前列腺癌。与一般人群相比,HIV 感染者进展为死亡的速度明显更快(调整后的危险比,2.02;95%置信区间,1.14-3.58)。
即使大多数患者是通过筛查 PSA 检测出来的,该队列中的 HIV 感染者的疾病分期仍比一般人群更为晚期。在控制种族、诊断时肿瘤分期和年龄后,HIV 感染的前列腺癌患者的总体死亡率更高。可能需要针对 HIV 感染者个体化制定前列腺癌筛查方法。
