Abstract
Histological grading and pathological staging are relevant factors in the prognosis of patients with prostatic cancer. Of 115 consecutive patients with carcinoma of the protate that was staged fully before treatment, 16 had stage A2 disease. Low grade neoplasms were present in 6 of these patients and evidence of nodal metastases was documented at lymphadenectomy in 2. Similarly, 4 of 35 patients with low grade stage B1 disease had nodal metastases. With the enzymatic and/or radioimmunoassay techniques for acid phosphatase determination it was not possible to select those patients with nodal metastases. Low grade, low stage carcinoma of the prostate apparently retains a potential for metastatic disease. Acid phosphatase determinations are unreliable in detecting bulky regional nodal involvement.
