Prostate carcinoma--the value of T stage and grade in predicting metastases and prognosis. A cost-effective approach to clinical staging.
In order to evaluate the initial T stage and tumour grade as predictors of metastatic disease and prognosis in adenocarcinoma of the prostate, 963 patients were reviewed. Of the patients, 41% presented with metastatic disease. Stage T4 tumours were associated with a consistently poor prognosis, and 70% of such patients had demonstrable distant metastases. No patient with TOf local disease had metastases or died of prostate cancer during follow-up. The incidence of metastases was also low in stages T1 and T2. High tumour grade correlated strongly with more advanced disease. Using this information a more cost-effective approach to the staging of prostate carcinoma is proposed.
