ABSTRACT
OBJECTIVE: To demonstrate the utility of fine needle aspiration biopsy in the diagnosis of prostatic tumors, basically carcinoma of the prostate. METHODS/RESULTS: The clinical records of 497 patients who underwent fine needle aspiration biopsy were reviewed. Age, skin color, clinical diagnosis by DRE, transrectal core biopsy, correlation between clinical and histological diagnosis, distribution according to type of adenocarcinoma, correlation between cytological and histological diagnosis, and complications were analyzed. Of the 497 patients, 162 had histological confirmation. Of these 162 patients, the Galen and Gambino statistical method was utilized in 132 which represented the true negatives and positives. Sensitivity was 86%, specificity 96%, positive predictive value 91%, negative predictive value 93%, and efficiency was 92%. The complication rate was low. CONCLUSIONS: Fine needle aspiration biopsy is a safe and efficient diagnostic method in prostatic tumors and causes minimal discomfort to the patient.
