Screening for prostate cancer
Ce dossier présente la mise à jour des recommandations 2012 de l'"US Preventive Services Task Force" concernant le dépistage du cancer de la prostate par dosage sérique de l'antigène prostatique spécifique
The US Preventive Services Task Force (USPSTF) has recently published recommendations on screening for prostate cancer in asymptomatic men.
What Is Prostate Cancer ?
The prostate gland sits just below the bladder in men and is responsible for making fluid that is part of semen. Prostate cancer is one of the most common cancers in men; however, it is an unusual type of cancer because it has a wide range of clinical behaviors (how serious or not serious the cancer is). Some prostate cancers can be very rapidly growing and life-threatening, but most progress very slowly and never cause any symptoms or become life-threatening. Many men with prostate cancer end up dying of other causes, never knowing that they had prostate cancer. Autopsy studies have shown that among men in their 70s who died of causes other than prostate cancer, more than 1 in 3 also had prostate cancer.
Looking for prostate cancer via screening often results in finding cancers that never would have become health problems otherwise. This is called overdiagnosis, which can lead to unnecessary treatment (overtreatment). Prostate cancer treatment can have serious side effects such as impotence and urinary incontinence. For these reasons, screening for prostate cancer is controversial.
