The role of pretreatment serum albumin to predict pathological stage and recurrence among radical prostatectomy cases.
Serum albumin level has been implicated as a prognostic factor in various cancers, however it has not been studied in early stage prostate cancer. We examine the clinical prognostic value of the readily available pretreatment albumin level as a marker for determining staging and prognosis for men undergoing radical prostatectomy. A retrospective review was performed on 354 patients who underwent a radical prostatectomy at a tertiary facility from 15 April, 1990 until 3 December, 1996 who had a pretreatment serum albumin within 6 months prior to surgery. Albumin levels were analyzed and compared to the values of standard prognostic factors to assess the ability of albumin to predict pathological stage and serological recurrence by PSA level after radical prostatectomy. Albumin level was not of value in predicting serological disease recurrence, but interestingly was an independent prognostic factor in predicting risk of nonorgan-confined disease (T3 or T4). Our data also showed that, as expected, grade and pretreatment PSA levels were independent predictors of pathological stage. Albumin appears to be of clinical utility to augment assessment of pretreatment pathological stage. However, it is not of value in predicting serological disease recurrence following radical prostatectomy. Further study in other cohorts and in using additional analysis such as neural networks is indicated. Prostate Cancer and Prostatic Diseases (2000) 3, 186-190
