[Lymphography in cancer of the prostate]

The frequency and area of lymphogenic metastasis with relation to the histological structure, differentiation and degree of local dissemination of a primary tumor were determined at lymphography of 114 patients with prostatic cancer. Lymph node involvement was often observed in poorly differentiated and solid trabecular adenocarcinoma, scirrhous cancer and locally disseminated tumors extending beyond the prostatic capsule. Metastases were usually located in the external and common inguinal lymph nodes. Lymphography was shown to be indicated to patients with a local spread of prostatic cancer (T2, T3 and T4).
