Resume

La cyto-aspiration prostatique transrectale à l’aiguille fine est une méthode simple, dépourvue de complications et reproductible. La sensibilité de la cyto-aspiration dans le diagnostic de carcinome prostatique est de 70 à 95%, et sa spécificité de 65 à 95%, par rapport à la méthode biopsique. La corrélation des grades cytologique et de Gleason est de 75%. Les complications liées à la cytoaspiration transrectale sont très faibles, à condition de prescrire une antibiothérapie prophylactique. Les indications de la cyto-aspiration prostatique sont limitées, le diagnostic formel et le grading étant apportés par l’histopathologie. Les biopsies guidées par échographie sont effectuées dans l’étape diagnostique initiale et de stadification des cancers de la prostate. La cyto-aspiration devrait plutôt être utilisée pour le diagnostic précoce, de façon systématique chez les patients consultant en urologie.

Transrectal fine-needle aspiration of the prostate

Abstract

The diagnosis of prostate adenocarcinoma by fine-needle aspiration cytology (FNAC) has taken long to accept as a simple, safe and reproducible procedure. The transrectal approach, as described for many years, remains the simplest method. Cytological samples need to be fixed with adequate solutions. Local anesthesia is not useful, and ultrasonographic guidance is not necessary. Reported sensitivity and specificity values of FNAC are 70–95% and 65–95% respectively, when biopsy is taken as the diagnostic reference. The correlation of cytological and Gleason’s grading is about 75%. Complications after transrectal sampling are very low, provided previous antibiotherapy is administrated. The indications for performing FNAC are limited, a histopathological diagnosis being necessary. Ultrasonographicallyguided biopsies should be done in every diagnostic and staging attempt. FNAC should be done more systematically in order to provide early diagnosis in patients presenting with non specific urologic symptoms.
