CERVERA DEVAL, J.; MORALES OLAYA, F.J.; JORNET FAYOS, J. y GONZALEZ ANON, M.. Diagnostic value of the second prostate biopsies in males of risk: Study stratified by value of PSA. Actas Urol Esp [online]. 2004, vol.28, n.9, pp.666-671. ISSN 0210-4806.
OBJETIVE: To value the diagnostic yield of the second prostate biopsy (BP). PATIENTS AND METHODS: To 116 males with BP previous to kindliness surrendered to 2 or more BP for sextants guided with ultrasounds (US). The criteria of inclusion were: BP previous suspicious (PIN), high PSA, TR or suspicious US. RESULTS: The average time passed between the first and following biopsy was 13 ± 11 months. 35 malignant and 4 premalignant ones were obtained in the second realized biopsies, which gives a diagnostic global yield of 33.6%. When we stratify for value of PSA, we obtain that with PSA <4 ng/ml the yield was 23%, for PSA 4-10 ng/ml the yield was 32% and for PSA >10 ng/ml of 34,6%. CONCLUSION: The repetition of the serial biopsy of prostate in patients of risk, improves the diagnostic yield and eliminates the false negatives of prostate carcinoma.
