Prostate cancer is the most diagnosed noncutaneous malignancy and the second most common cause of cancer death among men in the United States. Risk factors include older age, family history of prostate cancer, and Black race. Screening via prostate-specific antigen testing may lead to a small reduction in prostate cancer-specific mortality, with no reduction in all-cause mortality, but it can cause significant harms related to false-positive test results, unnecessary biopsies, overdiagnosis, and overtreatment. Shared decision-making is strongly recommended by all national guidelines before initiating screening. Most guidelines recommend screening every 2 to 4 years in men 55 to 69 years of age at average risk. After a positive prostate-specific antigen test result (more than 4 ng/mL), the test should be repeated. If the prostate-specific antigen level is still elevated, next steps include multiparametric magnetic resonance imaging, assessment of urine or blood biomarkers, and referral to urology. Active surveillance is increasingly accepted as the preferred standard of care for patients with newly diagnosed low-risk prostate cancer, because it is associated with similar long-term survival and better quality of life than curative treatment. The primary intent of screening is to identify patients with clinically significant prostate cancer who may benefit from curative treatment while minimizing the detection of clinically insignificant cancer.
前列腺癌是美国男性中最常见的非皮肤恶性肿瘤,也是癌症死亡的第二大主要原因。风险因素包括年龄较大、前列腺癌家族史和黑种人。通过前列腺特异性抗原检测进行筛查可能会导致前列腺癌特异性死亡率略有降低,全因死亡率没有降低,但它会导致与假阳性检测结果、不必要的活检、过度诊断和过度治疗相关的重大危害。所有国家指南都强烈建议在开始筛查前进行共同决策。大多数指南建议在平均风险的 55 至 69 岁男性中每 2 至 4 年进行一次筛查。在前列腺特异性抗原检测结果呈阳性(超过 4ng/ml)后,应重复该检测。如果前列腺特异性抗原水平仍然升高,则下一步包括多参数磁共振成像、尿液或血液生物标志物评估,以及转介泌尿科。主动监测越来越被接受为新诊断的低危前列腺癌患者的首选治疗标准,因为它与更有效的治疗方法相比具有相似的长期生存率和更好的生活质量。筛查的主要目的是识别可能从治愈性治疗中获益的具有临床意义的前列腺癌患者,同时尽量减少对临床意义不大的癌症的检测。
