For most healthy men, however, the United States Preventive Services Task Force (USPSTF) – a leading independent panel of experts on prevention and primary care – has publicly recommended against widespread PSA tests. Several well-managed, randomized, long-term human trials have shown almost no survival benefit for those who are screened, diagnosed, and treated, compared to those who were never screened.
但是，对大部分健康男性来说，美国预防服务专职小组（USPSTF）——由预防和初级治疗专家组成的独立领导小组——公开反对普及PSA测试。不少精心组织的长期随机人体试验表明，与从未被筛查人群相比，被筛查、诊断和治疗的人群几乎没有获得任何生存优势。
