A radical tumor resection and vascular plastic with xenopericardium as part of complex therapy in a patient with second relapse of nephroblastoma. Case report and literature review

In spite of a relatively good prognosis of most patients with nephroblastoma, there are some subgroups characterized by different unfavorable prognostic factors, in which the overall prognosis is much worse. In particular, this can be applied to patients with very high risk relapse. As in these cases the tumor is often resistant to most chemotherapy modalities, the quality of surgical control is of utmost importance.

We present a case of a 9-year-old patient with second local nephroblastoma relapse involving a large portion of inferior vena cava. During the course of complex therapy a radical surgical resection with vascular plastic by xenopericardium implant was performed. The follow-up, albeit short, yields no signs of disease progression or graft malfunction.

This case demonstrates the possibility of successful vascular plastic in a child with relapsed tumor. This method may allow more radical tumor resection.
