Introduction: Renal Cell Carcinoma (RCC) accounts for 3% of adult carcinomas. It is one of the most deadly urological cancers with disease specific mortality of 40%. Venous wall invasion or tumor thrombus is seen in 4% to 10% of patients (= T3b), with 5 years survival from 40% to 60%. The only curative treatment is tumor thrombus and kidney en bloc removal. Materials and Methods: All the clinical, radiological and pathological data of the patients submitted to radical nephrectomy at our institution through 2008 and 2009 was reviewed. Results: We found venous involvement in seven of the 69 patients (10,1%). Average age was 58 years (32-72); Six patients (85,7%) had renal vein invasion; four (57,1%) had renal vein thrombus and three (42,9%) had cava vein thrombus (two at level II and one at level III). Three were submitted to cavotomy with no complications. One was lost to follow-up; two died on early post-op (three to seven days); one died due to systemic disease progression; the other three have disease progression. Conclusions: RCC with vena cava involvement has a poor natural history, but this can be dramatically changed with an aggressive and complete surgical attitude. For that means, multidisciplinary teams are mandatory.
