title: [Stage T1a prostatic cancer: long-term retrospective study of 27 patients].
abstract: OBJECTIVE
  The natural history of stage T1a prostate cancer is generally favourable, but is nevertheless associated with a considerable progression rate of 7% to 27% depending on the study. The objective of this study was to identify possible predictive criteria of tumour progression to improve patient surveillance and early treatment.
  
  
  METHODS
  27 patients with stage T1a prostate cancer according to the TNM 97 classification, were followed for a mean duration of 79 months (range: 24-132, median: 68). A complementary assessment was performed in patients under the age of 70 years, and a strict clinical (DRE) and laboratory (PSA) surveillance protocol was performed in all patients. The initial mean PSA was 7 ng/ml and the mean Gleason score was 4.8.
  
  
  RESULTS
  20 patients (75%) did not present any clinical and/or laboratory signs of progression and were therefore not treated. Seven patients (25%) received treatment with a mean follow-up of 63 months (radical prostatectomy in 2 cases, external beam radiotherapy in 1 case, endocrine therapy in 4 cases). All patients are alive and in complete remission at last follow-up.
  
  
  CONCLUSIONS
  Based on our results and a review of the literature, conservative management based on strict, long-term surveillance, is a frequent approach to stage T1a prostate cancer confirmed by negative biopsies of the residual capsule. The PSA velocity is the key to surveillance, and the only factor of predictive of tumour progression that can be really used in routine clinical practice. However, our study showed tumour progression in 25% of cases, raising the question of curative treatment, especially in young patients.
