Reliability of cytological grading of prostatic carcinoma compared with histological grading

Thirty prostatic carcinomas diagnosed simultaneously by fine needle aspiration cytology and punch biopsy were graded into three groups according to their cytological and histological appearances. Among them 23 carcinomas were graded equally by both methods. Cytological examination appears to be suitable for grading prostatic carcinoma, thus being a possible indicator of the patient's prognosis and response to hormonal therapy. In addition to the results obtained here, fine needle aspiration cytology has many advantages such as simplicity, quickness and safety. With increase of attention of urologists and pathologists to fine needle aspiration cytology, this evaluation will become comparable to the histological examination not only as a routine diagnostic tool.
