[Incidental prostatic cancer: T1a-T1b. Our experience after observation/radical surgery and literature review].
OBJECTIVE
To analyse the progress of T1a and T1b prostate cancer diagnosed in our hospital.


METHODS
Retrospective study of 40 patients in T1a-T1b clinical stage diagnosed with prostate adenocarcinoma in our hospital, from 1986 to 1999. A restaging biopsy was performed on the 16 T1a patients after initial diagnosis and control. A radical prostatectomy was performed on the 24 T1b patients. They were all monitored every six months with rectal exam and PSA. We analysed biological and/or clinical progression, time to progression, mortality caused by the tumour and survival.


RESULTS
None of the 16 patients with T1a clinical stage presented tumour progression, with a median follow-up of 90 months. 12,5% of the 24 T1b cases presented tumour progression, with a median follow-up of 70 months. Cancer-specific mortality was one patient (4,16 %) in the T1b group.


CONCLUSIONS
Observation and follow-up with PSA and rectal exam appears to be a good option for T1a clinical stage, given the good prognosis. Our results show that patients with T1a clinical stage and good prognostic factors could be at a similar risk of suffering from a new prostate cancer as the normal population, although prospective studies are required to validate these results. T1b cases require active treatment and closer monitoring.
