Abstract

Objective: To describe our surgical experience and clinical outcome in laparoscopic radical nephrectomy (LRN) for renal cell carcinoma (RCC) with level 1 renal vein tumor thrombus.

Patients and methods: 11 patients with RCC level 1 renal vein tumor thrombus were treated by LRN plus thrombectomy. The mean age was 66.8 years (SD ±11.313); the mean body mass index was 24.76 (SD ±5.091). In all cases, the surgical technique was defined by tumor characteristics and the surgeon's preferences.

Results: Surgery was technically successful in all 11 patients. A hand-assisted approach was performed in 3 patients, while pure laparoscopy was used in 8. The mean surgical time was 108.3 min (SD ±28.284); the mean estimated blood loss was 108.33 ml (SD ±106.066); the average hospital stay was 2.8 days (SD ±0.707). There was 1 intraoperative complication (splenic laceration) that was managed laparoscopically. Pathologic examination confirmed RCC in all cases. There were no positive surgical margins. With a mean follow-up of 29 months (27-39), 2 patients had a recurrence.

Conclusion: This report provides further evidence of the technical feasibility, safety and oncologic adequacy of the laparoscopic approach in RCC with level 1 renal vein involvement. A longer follow-up and multi-institutional studies are needed to adequately evaluate its potential oncologic benefit.
