Purpose: Little is known why certain prostate cancers are missed on biopsy. In patients with a needle biopsy diagnosis of cancer it is also unknown whether repeat needle biopsy provides useful information to predict extent of disease.Materials and Methods: In the pathology laboratory we performed sextant and transition zone needle biopsies on 193 radical prostatectomy specimens from men with nonpalpable cancer detected on needle biopsy (stage Tie) using an 18 gauge biopsy gun, Radical prostatectomy specimens were then serially sectioned, totally embedded, mapped and staged.Results: The transition zone biopsy by itself was positive in only 2.1% of cases, demonstrating the lack of-usefulness for this particular biopsy. Despite cancer on preoperative needle biopsy in all cases, 31% showed no cancer on repeat sextant transition zone biopsy. In a multivariate analysis (variables included radical prostatectomy tumor volume, radical prostatectomy tumor location, prostate gland size and radical prostatectomy grade) decreased tumor volume (p
