Radical surgical resection of metastases is an important prognostic factor for survival of patients suffering from solid pediatric tumors. The aim of this study is to evaluate the efficacy of median sternotomy as treatment option for the resection of multiple bilateral lung metastases in children with different tumor entities. Furthermore, the sensitivity of preoperative imaging (CT) was assessed by intraoperative findings.

Between 2002 and 2007, thirteen children (4x sarcoma, 4x nephroblastoma, 5x hepatoblastoma) underwent median sternotomy for resection of bilateral lung metastases after R0 – resection of the primary tumor. In 6/13 cases, the sternotomy was combined with the primary tumor resection.

Median patients at the first operation age was 5 years (range: 11 months – 17 years). The median total number of resected metastases per operation was 9 and ranged from 0 to 65. In 13/16 operations, the intraoperative number of metastases did not agree with the preoperative radiological work-up. Median hospital stay was 14 days (range from 9 to 36 days). 10/13 children are alive after a median follow–up of 13 months (range from 6 to 66 months).

Median sternotomy is an adequate treatment modality for the resection of bilateral pulmonary metastases as a one stage procedure. The combination of primary tumor resection with sternotomy should be considered as treatment option. Complete resection of metastases of solid pediatric tumors should be aimed for in order to increase the survival of these patients.
