Neoplastic thrombosis in the renal cancer

Data pertaining to 193 patients with renal cancer, evaluated and treated in our department from 1966 to 1982, were subsequently examined and studied with regard to survival in relation to the pathological stage. In our experience the transluminal propagation of a tumor thrombus within the renal vein or the inferior vena cava, as an isolated condition, does not appear to worsen the prognosis as does the lymph node involvement.
