A Study of 48 Cases of Incidental Carcinoma of the Prostate Followed 10 Years or Longer

We reviewed 48 cases of incidental carcinoma treated conservatively. Patients with poorly differentiated, multiple foci or with well differentiated, multiple foci had a poor prognosis, whereas those with well differentiated, few foci (1 to 3) had a good prognosis. We believe that patients with multiple foci (poorly or well differentiated) should be treated aggressively, either by radical prostatectomy or radiotherapy. However, we recommend conservative treatment for patients with well differentiated, few foci.
