J. Morote et al., Value of routine transition zone biopsies in patients undergoing ultrasound-guided sextant biopsies for the first time, EUR UROL, 35(4), 1999, pp. 294-297
Objective: To analyze the efficacy of routine transition zone biopsies in p
atients undergoing ultrasound-guided sextant biopsies for the first time be
cause of a suspicious digital rectal examination (DRE) or an elevated serum
prostate-specific antigen (PSA) level. Patients and Methods: Du ring sexta
nt prostatic biopsy two additional transition zone biopsies were performed
in 164 consecutive patients: in 98 because of a serum PSA of >4.0 ng/ml, an
d in 66 because of a suspicious DRE. Results: The overall cancer detection
rate was 46.9% (77/164). In 28 patients (36.4%) cancer was only detected in
the peripheral zone, in 2 (2.6%) only in the transition zone and in 47 (61
%) in both zones. Conclusion: Routine transition zone biopsies performed at
the time of a first sextant biopsy seem to have low efficacy.
