ABSTRACT
PURPOSE:
Radical nephrectomy with tumor thrombectomy is considered standard of care in patients with renal cell carcinoma. However, surgical ligation and interruption of the inferior vena cava is sometimes necessary when the tumor thrombus invades the inferior vena cava wall. This study assesses the outcomes in patients with renal cell carcinoma undergoing inferior vena cava ligation compared to inferior vena cava thrombectomy. MATERIALS ANDMETHODS:
We conducted a case controlled, retrospective study at a high volume single-center institution. All patients with renal cell carcinoma who underwent ligation without reconstruction were matched with patients undergoing thrombectomy in a 12 ratio based on preoperative renal function, renal cell carcinoma stage and intraoperative thrombus level. Endpoints were complications, change in renal function and mortality.RESULTS:
A total of 26 patients with renal cell carcinoma who underwent inferior vena cava ligation between 2005 and 2019 were matched with 52 patients who underwent inferior vena cava thrombectomy in the same time period. When compared to thrombectomy, patients undergoing ligation had higher 90-day readmission rate (19% vs 4%, p=0.025). The ligation group also had a higher postoperative complication rate (73% vs 39%, p=0.004) and higher rates of lymphedema (23% vs 8%, p=0.055). However, by 1-month followup the rate of persistent overall and major complications for both ligation and thrombectomy groups were comparable at 49% vs 31% (p=0.497) ad 8% vs 8% (p=1.000), respectively. Importantly, at 18-month followup, mean estimated glomerular filtration rate declines were similar between ligation group (8.5 ml/min/1.73 m2) and thrombectomy group (9.9 ml/min/1.73 m2; p=0.834). Differences in cancer-specific mortality (p=0.993) and all-cause mortality (p=0.756) were also not statistically significant.CONCLUSIONS:
The outcomes of inferior vena cava ligation compared to inferior vena cava thrombectomy for renal cell carcinoma are similar. Patients with inferior vena cava ligation initially face a more complicated postoperative course but in the longer term have similar renal function recovery, complication rates and survival.Palabras clave
