Lymphangiography in staging of carcinoma of the prostate: the potential value of percutaneous lymph node biopsy
A Prando, S Wallace, AC Von Eschenbach, BS Jing, JE Rosengren and DH Hussey
Bilateral pedal lymphangiography was performed in the staging of 208
patients with prostatic carcinoma. Forty-seven (23%) were found to have
lymph node involvement, and 40 of these 47 had Stage C disease. Nine per
cent of the Stage C1 patients (moderately advanced disease) and 37% of
Stage C2 (massive carcinoma) had lymph node metastases. The distribution of
the abnormal nodes was in continuity with the lymph node drainage from the
prostate. The external iliac nodes were the most frequent site of
metastases. Histological confirmation was obtained in 20 of the 40 positive
Stage C2 cases. More recently, percutaneous aspiration biopsy of the
opacified nodes was used to document the presence of metastic disease,
thereby extending the value of lymphangiography.
