title: Conservative management with symptomatic treatment and delayed hormonal manipulation is justified in men with locally advanced carcinoma of the prostate.
abstract: OBJECTIVE
  To examine the clinical course following surveillance and symptomatic treatment, and compare the outcomes of immediate and delayed hormonal treatment in men with locally advanced prostatic cancer.
  
  
  METHODS
  Of a consecutive series of 199 men (mean age 74 years) with T2-T4 Nx M0 prostatic cancer, 110 (55%) were followed until death and the rest had a mean follow-up of 4.2 years. Fifty-one men received immediate orchidectomy, 88 had this treatment delayed until metastatic progression, and 60 had the treatment in the intervening period. The actuarial survival was compared with the expected survival for an age-matched healthy population in Scotland. The adjusted effect of the timing for hormonal manipulation was assessed by including it with age, Gleason score and clinical stage in a multiple Cox regression.
  
  
  RESULTS
  The actuarial survival for the whole group was 17% less at 5 years and 15% less at 10 years when compared with the expected survival for an age-matched population in Scotland. This was despite the fact that their nodal status was unknown and also those with occult metastasis (elevated serum prostatic acid phosphatase, M1a) at presentation were not excluded. In terms of metastatic progression, overall survival and cause-specific survival, there was no significant difference between immediate and delayed hormonal treatment.
  
  
  CONCLUSIONS
  A conservative approach with surveillance and symptomatic treatment for locally advanced prostatic cancer is justified by the present evidence on disease progression and survival, which do not differ from alternative methods of treatment as reported in contemporary literature. This study has the limitations relative to the ideal of a prospective randomized trial on immediate versus delayed hormonal treatment, but the lack of significant differences in outcome even after adjustment for other established prognostic factors does suggest that there may be little to be gained from an immediate orchidectomy.
