Lymphographic findings in prostatic carcinoma with distant metastases.
From January 1976 to December 1981, 25 patients with prostatic carcinoma and distant metastases had lymphangiography (LAG) in their initial workup either to obtain a more precise definition of tumor extension or because at the time of LAG asymptomatic metastases had not yet been detected. In 18 patients extensive bone metastases were present while in seven the only indicator of bone metastases was bone scan (limited bone disease). Positivity rate was 48% (20% in T2 cases, 53% in T3-T4; 29% in limited bone disease, 53% in extensive bone metastases). No correlation was found between LAG positivity and degree of differentiation. Patients with N0 survived longer than patients with N2-N4; however, the difference in survival is not significant and seems to be linked to the extent of bone metastases. Our data substantiate that LAG is of no value in the staging of metastatic prostatic carcinoma.
