摘要:

评估基线中年前列腺特异性抗原 (PSA) 作为前列腺癌发生和进展的预测因子的作用的研究主要依赖于 PSA 筛查引入时代的队列。我们研究的目的是通过当代北美队列研究 60 岁之前的基线 PSA 作为发生致命性前列腺癌的预测因子的作用。我们的队列包括所有首次接受 PSA 的 40-59 岁男性1995 年至 2019 年间,我们的卫生系统将患者分为四类:40-44 岁、45-49 岁、50-54 岁和 55-59 岁。基线 PSA 是感兴趣的预测因子。致命性疾病被定义为在诊断时或随访期间因前列腺癌死亡或发生转移性疾病。通过将我们的数据库与密歇根人口记录登记处连接起来,获得了癌症特异性死亡率和总体死亡率。使用竞争风险回归来评估 PSA 与致命性前列腺癌之间的关联。研究期间共有 129067 名男性符合纳入标准。无癌症患者的中位随访时间为 7.4 年。对于 40-44 岁、45-49 岁、50-54 岁和 55-59 岁的男性,PSA <中位数的男性 20 岁时致命性前列腺癌的估计发病率分别为 0.02%、0.14%、0.33% 和 0.51% PSA ≥90% 的男性中,这一比例分别为 0.79%、0.16%、2.5% 和 5.4%。对于同一年龄组,PSA<中位值的男性在 20 岁时患任何前列腺癌的估计比率分别为 1.6%、2.9%、3.9% 和 5.8%,而 PSA < 中位值的男性则为 25%、28%、38% 和PSA ≥90% 的男性为 39%。在多变量分析中,与 PSA < 中位数的男性相比,PSA ≥ 90% 的男性患致命疾病的风险比为 7.48(95% 置信区间 [CI]:6.20-9.03)。在多变量分析中,与 PSA < 中位数的男性相比,PSA ≥ 90% 的男性前列腺癌发病率的风险比为 20.47 倍(95% CI:18.58-22.55)。局限性包括中位随访时间比之前的文献要短。在当代多样化的北美队列中,基线 PSA 是随后发生致命性前列腺癌风险的一个非常强的预测因子,这些队列接受了机会性 PSA 筛查。该关联性远大于多基因风险评分的关联性,证实 60 岁之前的基线 PSA 是调整后续筛查的最有效工具。与未筛查队列的研究相比,事件疾病和致死性疾病之间的区分差异较小,反映了筛查的影响。在这项研究中,我们发现单一基线前列腺特异性抗原(PSA)值可以强烈预测后续疾病患转移性前列腺癌的风险,以及死于前列腺癌的风险。因此,初始 PSA 水平可用于调整后续 PSA 测试的频率。版权所有 © 2024 欧洲泌尿外科协会。由 Elsevier B.V. 出版。保留所有权利。
Studies evaluating the role of baseline midlife prostate-specific antigen (PSA) as a predictor of development and progression of prostate cancer relied predominately on cohorts from the pre-PSA screening introduction era. The aim of our study was to examine the role of baseline PSA prior to the age of 60 yr as a predictor of developing lethal prostate cancer using a contemporary North American cohort.Our cohort included all men aged 40-59 yr who received their first PSA through our health system between the years 1995 and 2019. Patients were divided into four categories based on age: 40-44, 45-49, 50-54, and 55-59 yr. Baseline PSA was the predictor of interest. Lethal disease was defined as death from prostate cancer or development of metastatic disease either at diagnosis or during follow-up. Cancer-specific mortality and overall mortality were obtained by linking our database to the Michigan Vital Records registry. Competing-risk regression was used to evaluate the association between PSA and lethal prostate cancer.A total of 129067 men met the inclusion criteria during the study period. The median follow-up for patients free from cancer was 7.4 yr. For men aged 40-44, 45-49, 50-54, and 55-59 yr, the estimated rates of lethal prostate cancer at 20 yr were 0.02%, 0.14%, 0.33%, and 0.51% in men with PSA
