Abstract

OBJECTIVES:

To determine whether migration of pathological tumor stages in patients with clinically localized prostate cancer exists and whether this is due to an increasing frequency of treating patients with clinically insignificant cancer.

METHODS:

1,063 radical retropubic prostatectomies were performed in patients with clinically localized prostate cancer in one institution within 7.5 years (from 1992 until June 1999). All specimens were prospectively processed according to the Stanford protocol. These were then analyzed regarding the migration of pathological tumor stages and cancer volumes.

RESULTS:

Within the observation period, the annual rate of radical retropubic prostatectomies increased by 225% from 69 to 224 cases. The authors noted a decline of advanced tumor stages (from 65 to 40%) and an increase in pathological T2 tumors (from 30 to 55%). The rate of small cancers (<0.5 cm(3)) remained stable between 2 and 5% over the last 5 years.

CONCLUSION:

The data confirm trends which were observed in large US centers with increasing detection and treatment of localized prostate cancer without unnecessary treatment of clinically insignificant cancers.
