BACKGROUND: Resection of a Wilms tumor extending through the inferior vena cava into the right atrium represents a challenge to the pediatric surgeon. Exact preoperative diagnosis is essential to identify the tumor and its intravascular extension. To achieve a complete excision of the tumor cardiopulmonary bypass and hypothermia may be required. The feasibility of a complete resection is important as it guides subsequent therapy such as chemotherapy and radiation. PROCEDURE: In order to define these issues, we reviewed the records of 33 of 1,151. Patients enrolled in the SIOP 93-01/GPOH Study and the SIOP 2001/GPOH Study who had a tumor thrombus into the inferior vena cava and into the right atrium. RESULTS: The median age at diagnosis was 3.73 years. Twenty-four patients had a tumor thrombus into the inferior vena cava, in nine patients the thrombus reached into the right atrium. All patients were operated on; cardiopulmonary bypass was used in nine patients. There were no deaths intraoperatively. Twenty-nine children are still alive; four patients died, one patient due to aspiration and failed resuscitation, two patients died from a recurrent tumor, and one child due to an unresectable primary tumor. CONCLUSION: Our report suggests that Wilms tumor extending to the inferior vena cava and the right atrium is technical challenging, but with adequate preoperative diagnosis and a multidisciplinary surgical approach including cardiopulmonary bypass and hypothermia, the prognosis is favorable.
