Biochemical parameters as prognostic factors in prostatic adenocarcinoma.

The serum levels of creatinine (CR), alkaline phosphatase (ALP), acid phosphatase (ACP) and tartrate inhibitable acid phosphatase (TIAP) were related to Gleason score, TM-category, disease progression and survival in 325 prostatic adenocarcinoma patients followed up for over 12 years. Elevated serum levels of CR, ALP, ACP and TIAP were related to invasive and metastatic disease as well as with a high Gleason score. Elevated serum levels of CR, ALP, ACP and TIAP, all significantly predicted prognosis in a univariate analysis. In the M0 tumours, ACP and TIAP and TIAP had prognostic value, as they did in the T1-2M0 tumours respectively. Cox's multivariate analysis showed that serum creatinine level at diagnosis had independent prognostic value additional to the TM-classification, Gleason score and patient age. In the M0 tumours, ALP had independent prognostic significance additional to the T-category, Gleason score and patient age. In the T1-2M0 tumours, TIAP had independent prognostic value supplementary to the Gleason score, T-category and patient age, whereas in the T1M0 tumours, the gleason score was an independent prognostic parameter. The results indicate that these simple laboratory tests give important prognostic information in prostatic adenocarcinoma.
