[Renal adenocarcinoma with neoplastic thrombus in the inferior vena cava. Prognosis and operative risk].

10 cases of renal adenocarcinoma invading the lower vena cava and subjected at the Genoa urology clinic to radical nephrectomy and cavotomy, with thrombectomy or resection of the vena cava, are reviewed. Of 5 patients who did not present long-term metastasis, 2 are alive and in good condition at 30 and 64 months, one died from myocardial infarction after 34 months, and two died in the postoperative course from respectively renal insufficiency and myocardial infarction. In patients presenting long-term metastasis at the moment of surgery, results were poor: four patients died from 4 to 7 months later and only one patient, with bone metastasis, is alive after 33 months.
