Prostate cancer screening with prostate-specific antigen (PSA) test: a clinical practice guideline
A partir d'une revue systématique de la littérature publiée jusqu'en avril 2018 (5 essais incluant au total 721 718 hommes), cette méta-analyse évalue l'effet d'un dépistage du cancer de la prostate par dosage sérique de l'antigène prostatique spécifique sur la mortalité spécifique et la mortalité globale
What you need to knowPSA testing has increased the number of men diagnosed with and treated for prostate cancer, but many of these men would never have experienced any symptoms or death from prostate cancerThis guideline makes a weak recommendation against offering systematic PSA screening based on an updated systematic review. The recommendation is weak because there may be a small, though uncertain, benefit of screening on prostate cancer mortalityMen who place more value on avoiding complications from biopsies and cancer treatment are likely to decline screening. In contrast, men who put more value in even a small reduction of prostate cancer mortality (such as men at high baseline risk because of family history or African descent, or those concerned to rule out the diagnosis) may opt for screeningShared decision making is needed for men considering screening to make a decision consistent with their individual values and preferences. However, clinicians need not feel obligated to systematically raise the issue of PSA screening with their patientsWhat is the role of prostate-specific antigen (PSA) screening in prostate cancer? An expert panel produced these recommendations based on a linked systematic review.1 The review was triggered by a large scale, cluster randomised trial on PSA screening in men without a previous diagnosis of prostate cancer published in 2018 (box 1).2 It found no difference between one-time PSA screening and standard practice in prostate cancer mortality but found an increase in the detection of low risk prostate cancer after a median follow-up of 10 years.Box 1 Results of the CAP Randomized Clinical Trial2This cluster-randomised trial of 419 582 British men was published in March 2018. After a median follow-up of 10 years, there was no significant difference in prostate cancer-specific mortality in men receiving care by general practices randomised to a single PSA screening intervention compared with men receiving care … RETURN TO TEXT
