ABSTRACT
Introduction: Prostate cancer is a malignant tumor with a high incidence in Mexico, causing
6,296 deaths in 2016. At the present time, cylinder length for transrectal ultrasound-guided
sextant prostatic biopsy has not been established.
Objective: Evaluate the difference in the
diagnosis of prostatic carcinoma through 12-core biopsy using either 22 or 15 mm cylinders.
Material and methods: This is a retrospective analysis of 40 patients with ultrasound-guided
transrectal biopsies, increased Prostate Specific Antigen (PSA) and suspicious rectal
examination. We reviews medical records from patients ascribed to the Regional General
Hospital (RGH) No.1, they were divided in two groups according to cylinder length (group
A; 22 mm, group B; 15mm). Presence or absence of cancer was recorded, comparing the type
of cylinder used. Results: The mean age was 66.1±10.5 years, PSA levels averaged 12.2 ng/
dL. No statistical difference was observed (p = 0.72) between cylinder lengths (22 vs 15 mm)
in the diagnosis of prostatic carcinoma. Conclusions: Prostate biopsy is the most important
detection tool for prostate cancer, no matter the length of the cylinder used.
