该工作组指出,由于前列腺癌通常进展缓慢,筛查发现的许多肿瘤可能永远也不会对患者造成损害。但它们还是受到了治疗。因此,该检测救人不多,却害得太多人接受了不必要的手术或放疗,以致于阳痿或尿失禁。
An editorial accompanying the articles, by Dr. David F. Penson, the chairman of urologic surgery at Vanderbilt University Medical Center, acknowledged that too much screening could do harm but suggested that the pendulum had swung too far the other way.
范德堡大学医学中心(Vanderbilt University Medical Center)的泌尿外科主任戴维·F·彭森(David F. Penson)博士在随新研究刊发的评论文章中承认筛查过多可能有害,但也不至于像现在认为的那么夸张。
Rather than issuing a blanket recommendation against screening, Dr. Penson said, it would be better to “screen smarter” by testing most men less often and focusing more on those at high risk.
彭森博士并没有泛泛地建议反对筛查,相反,他认为更好的应对方法是“智慧地筛查”,即扩大筛查面,降低筛查频率,且更加关注高危人群。
One of the new studies, by researchers from the American Cancer Society, found that early-stage diagnoses of prostate cancer per 100,000 men age 50 and older dropped to 416.2 in 2017, from 540.8 cases in 2008, with the biggest decrease occurring from 2011 to 2017 — after a draft of the task force guidelines was released in October 2011. The authors estimated that the total number of diagnoses decreased to 180,043 in 2017 from 213,562 in 2011 — a difference of 33,519 cases.
