Prescription du dosage de PSA et information des patients : enquête transversale auprès de 212 patients lors du prélèvement sanguin

Abstract : Background: The PSA test is a bioassay massively prescribed. However, its consensus-based indications are limited. When screening for cancers, its indication remains ambiguous for prescribers. However, academic circles (HAS and AFU) seem to have come to a consensus both nationally and internationally. Given this divergence between recommendations and practice, we found it interesting to first deal with the physicians' prescriptions of the PSA tests, in all indications, according to the patients' testimonies; and then to compare them to the latest recommendations from the HAS from May 2013 and to explore the perception and understanding of the given information. Method: Cross-sectional descriptive and multicenter study in the region of Bordeaux (Gironde, France) over 4 months through a questionnaire given to patients who were going to a testing laboratory with a prescription for a PSA assay. Results: General practitioners were the first prescribers of the PSA assay (83.49%) essentially total PSA (80.66%), mainly for patients who didn't have or had a few symptoms (64.62%) stating that it was a systematic check up (46.70%) and the screening for prostate cancer (37.74%) considered as the first reason for a measurement. 41.04% of the patients had a rectal examination. Asymptomatic patients who had PSA measurements were more numerous than patients who had symtoms. The information was well recieved (77.83%) and well understood (75.47%) by the patients. It didn't have an impact on the prescriptions in the context of screening for prostate cancer (p= 0.27). Conclusion: Our study reveals that a certain confusion still remains in its indication for a screening for prostate cancer despite the latest official recommendations. A clearer information could be given to patients thanks to a standardized rating which we have suggested. It could be assessed in another study.
