Prostate cancer (PCa) screening tools, particularly digital rectal examination (DRE), are under scrutiny. This review assesses the utility of DRE in PCa screening.
Recent studies reaffirm the DRE's sensitivity and specificity, a higher PCa detection rate with PSA in conjunction with DRE, and a slightly elevated risk of clinically significant PCa (CSPC) in those with elevated PSA and suspicious DRE. Studies confirm high accuracy of MRI in identifying CSPC, with ongoing research exploring its screening potential. DRE alone lacks accuracy for PCa screening, often resulting in missed diagnoses and unnecessary biopsies. Its supplementary use with PSA marginally increases detection rates of identifying a small percentage of CSPC, but the benefit remains questionable. Emerging evidence suggests MRI has the potential as a superior screening tool compared to DRE, although direct comparative studies are lacking. Overall, the DRE has a limited role in current PCa screening.
前列腺癌(PCa)筛查工具,特别是直肠指检(DRE),正受到审查。本综述评估了 DRE 在 PCa 筛查中的作用。
最近的研究再次证实了 DRE 的敏感性和特异性,联合 PSA 检测时 DRE 可提高 PCa 的检出率,且 PSA 升高伴 DRE 可疑时 CSPC 的风险略有增加。研究证实了 MRI 对识别 CSPC 的高准确性,目前正在探索其筛查潜力。DRE 单独用于 PCa 筛查的准确性不足,经常导致漏诊和不必要的活检。联合 PSA 检测可略微提高小比例 CSPC 的检出率,但获益仍存在争议。新出现的证据表明,MRI 作为一种优于 DRE 的筛查工具具有潜力,尽管缺乏直接比较性研究。总的来说,DRE 在目前的 PCa 筛查中作用有限。
