Resumo: | PURPOSE: To determine if there are any differences in the zonal distribution and tumor volumes of familial and sporadic prostate cancers (PC) in men undergoing radical prostatectomy. MATERIAL AND METHODS: 839 patients underwent a radical prostatectomy in the absence of prior neoadjuvant therapy between 1987 and 1996. Telephone interviews were conducted to obtain an updated family history. A positive family history was defined as the diagnosis of PC in at least one first degree relative. Prostatectomy specimens were examined to determine the number of tumor foci, zonal origin of the dominant tumor focus, tumor volume of the largest cancer focus, total tumor volume, Gleason score and stage, and the surgical margin status. Results were stratified according to family history and ethnicity. RESULTS: We successfully contacted 437 patients (52%). Prostatectomy specimens from 55 patients were excluded from review due to a history of prior transurethral resection of the prostate (n = 26) or uncertain pathological stage (n = 29). Of the remaining 382 patients, 76 (20%) reported having a first-degree relative with PC. Statistical analysis revealed no significant differences in the pathologic variables between the two groups of patients with or without a family history of PC. CONCLUSIONS: Familial and sporadic PC share similar characteristics. No histopathological differences account for the increased positive predictive value of PC screening tests among patients with a family history of PC. |
