ABSTRACT
AIMS:
Prostatic cancer may remain organ-confined indefinitely; in a number of patients, however it gives rise to clinical symptoms and death. The biological behaviour of this tumour mostly remains difficult to predict. A promising tool for diagnosis and prognosis of some human tumours is the chromatin assembly factor-1 (CAF-1), involved in the control of higher order chromatin organization. The aim was to explore the role of CAF-1/p60 protein as a new prognostic marker for prostatic cancer. METHODS ANDRESULTS:
The expression of CAF-1/p60 was evaluated by immunohistochemistry and Western blotting in a selected series of prostatic cancers and in prostatic cancer cell lines. Results were compared with clinicopathological data and outcome of patients. CAF-1/p60 was expressed in all cases, with a linear increase from low-grade tumours (Gleason score <7) to high-grade prostatic cancers (Gleason score >7). By comparing results with follow-up data, a significant association between overexpression of CAF-1/p60 and unfavourable behaviour of prostatic cancer emerged, and its predictive value was independent of classical prognostic factors.CONCLUSIONS:
In our series of cases, overexpression of CAF-1/p60 characterized prostatic cancers with a worse prognosis. CAF-1/p60 has a potential role as a new reliable prognostic biomarker for prostatic cancer.
