Usefulness of aspiration cytology in prostate cancer detection

Aspiration cytology and core needle biopsy were performed in 79 patients who were suspected of having prostate cancer. Aspiration cytology and TURP were done in 77 cases not suspected of the disease. In the former group, they were both positive in 13 cases, aspiration cytology was negative and core needle biopsy positive in 4, and the reverse in 3 cases in whom cancer was confirmed by repeat core biopsy. All of the latter group were judged by aspiration cytology as being benign. Three cancers were detected by TURP. Aspiration cytology is a recommendable method in subjects with suspected prostate cancer.
