Erythrocyte polyamines and prognosis in stage D2 prostatic carcinoma patients.
We studied 43 patients with newly diagnosed, untreated, stage D2 prostatic carcinoma, and correlated the initial performance status, hemoglobin, prostate specific antigen levels, tumor Gleason grade, extent of disease on the bone scan, and erythrocyte spermidine and spermine levels with progression. Three patients died of unrelated causes and were excluded from the study, 16 remained in remission with a mean 28 +/- 11 months of followup and 24 had progression (18, or 75%, of whom died of the cancer) with a mean 12 +/- 9 months of followup (p < 0.05 for followup) after initiation of hormonal therapy. Pretreatment performance status, hemoglobin, and erythrocyte spermidine and spermine levels were correlated with progression, hemoglobin and spermine being the most significant independent variables (p = 0.006 and p = 0.001, respectively). Concerning cause-specific survival, only hemoglobin and spermine erythrocyte levels were significant independent variables (p = 0.02 and p = 0.0025, respectively). If confirmed, polyamine erythrocyte levels obtained by a simple blood sample could discriminate at diagnosis patients with a high risk of rapid hormonal relapse who may benefit from a more aggressive primary management.
